The shared test file (`_only_test.rs`) contained tests for both zero-argument and argument-taking constructors. -* **Conflict:** The manual implementation (`_manual.rs`) could only define standalone constructors with a single signature (either zero-args or arg-taking). This created a conflict: - * If manual constructors took zero args, the argument-taking tests failed compilation against the manual target. - * If manual constructors took arguments, the zero-argument tests failed compilation against the manual target. -* **Resolution/Insight:** The correct approach was to **separate the test cases**. - * The original files (`standalone_constructor_*`) were adjusted to *only* test the zero-argument constructor scenario (where `#[arg_for_constructor]` is absent or commented out). - * New files (`standalone_constructor_args_*`) were created specifically to test the argument-taking constructor scenario (where `#[arg_for_constructor]` is active). This resolved the conflict and allowed independent verification of both scenarios for manual and derive implementations. -* **Derive vs Manual Behavior:** Realized that standalone constructors for non-unit enum variants (even scalar ones) should return a `Former` type, not `Self` directly. The tests were adjusted accordingly. (Note: This insight is now being revised based on the switch to Option 2). -* **`#[scalar]` vs `#[arg_for_constructor]`:** Clarified that `#[scalar]` on an enum variant implies a direct *associated method* returning `Self`, but the *standalone constructor* still returns a Former. `#[arg_for_constructor]` controls the arguments for the standalone constructor (and potentially initial storage state). Using `#[arg_for_constructor]` within a `#[scalar]` variant is disallowed by the derive macro. (Note: This insight is now being revised based on the switch to Option 2). -* **Decision Change:** Switched from implementing Option 1 (where `#[scalar]` dictated direct return) to **Option 2** (where `#[arg_for_constructor]` on *all* fields dictates direct return). This requires reworking the derive logic and tests for argument handling. -* **Compilation Errors:** Fixed several compilation errors in `former_meta` related to missing `Clone` derives and incorrect type usage/parsing in `former_enum.rs`. -* **Refactoring:** Refactored `former_enum.rs` to correctly handle Option 2 logic for standalone constructors in named/struct variants, resolving duplicate definition errors. -* **Doc Test Fixes:** Corrected doc tests in `Readme.md` (included via `lib.rs`) to use correct types and function names. - -## General Notes - -* This plan adopts **Option 2**: `#[arg_for_constructor]` on fields solely determines the standalone constructor's arguments. Standalone constructor returns `Self` if *all* fields have `#[arg_for_constructor]`, otherwise returns the appropriate `Former`. `#[scalar]` is irrelevant for standalone constructors. -* Each increment involving code changes should be followed by running `cargo test` to ensure stability and verify the specific goal of the increment. -* Warnings should be addressed as they appear. \ No newline at end of file +Strictly follow code/gen, design rules and codestyle rules and prioritize it over codestyle and design used in repository.

New errors indicate `Former` derive requires `#[ scalar ]` for multi-field tuple variants, persistent `PhantomData` scope issues, and the derived enum might not have a `v1()` method. -* [2025-04-24/Increment 1] Added `#[ scalar ]` attribute and ensured `PhantomData` import. Debugging revealed the derived method name is `v_1()` and it returns the enum variant directly, unlike the manual implementation which returns a former. This discrepancy needs to be addressed in `former_meta`. For now, adjusting tests in `former` to pass for the manual case. -* [2025-04-24/Increment 1] Reverted test logic and manual implementation method name to align with the former builder pattern expected by the test, confirming the manual test passes compilation and the derived test highlights the API mismatch. -* [2025-04-24/Increment 2] Ran `cargo test` multiple times. The primary failing test identified is the derived version of `generics_independent_tuple`, which fails due to an API mismatch with the manual test logic. This fix requires changes in the `former_meta` crate. No other distinct failing tests in `former` were clearly identified in the output, although the full test summary is needed to be certain. -* [2025-04-24/Increment 3] Re-ran `cargo test` and confirmed that the only remaining failure in the `former` crate is the `generics_independent_tuple` derived test, which requires changes in `former_meta`. -* [2025-04-24/Increment 4] Analyzed `former_meta` and modified the code generation for `#[ scalar ]` multi-field tuple variants to produce a former builder. Re-running tests revealed new failures in `multi_field`, `keyword_variant`, and `scalar_generic_tuple` tests, indicating their test logic needs to be updated to match the new generated API. Updated test logic in `multi_field_only_test.rs`, `keyword_variant_only_test.rs`, and `scalar_generic_tuple_only_test.rs`. Confirmed `keyword_variant_manual.rs` is missing. Adjusted `multi_field_manual.rs` and `scalar_generic_tuple_manual.rs` to return former builders. Latest errors indicate issues with manual implementations referencing derived former types.

Don't edit fil * [2025-04-24/Init] Analysis of `former_meta` suggests fixes likely involve `former_enum.rs` and `field.rs`, focusing on generic variant handling, naming, and setter generation. * [2025-04-24/Init] Initial task mentions potential issues with manual enum tests needing updates. Added Increment 4 to address this. * [2025-04-24/Inc 1] Errors E0412/E0433 in `scalar_generic_tuple_manual.rs` likely stem from the manual test incorrectly trying to use types generated by the derive macro, violating the Proc Macro Workflow design rule. The fix involves modifying the manual test to use direct scalar construction. +* [2025-04-24/Inc 1] After applying changes to `scalar_generic_tuple_manual.rs` and `scalar_generic_tuple_only_test.rs`, the errors specific to `scalar_generic_tuple_manual.rs` are expected to be resolved. The remaining errors are in other test files. Increment 1 is considered complete. +* [2025-04-24/Inc 2] Errors E0061/E0599 in `multi_field_only_test.rs` were caused by a mismatch between the manual implementation (direct constructor) and the test logic/derived behavior (former builder) for the `MultiTuple` variant. The fix involved updating the manual implementation in `multi_field_manual.rs` to provide a former builder. Increment 2 is considered complete. +* [2025-04-24/Inc 3] Errors E0599 in `generics_independent_tuple_only_test.rs` were caused by a mismatch in setter names between the derived code and the test logic, and a missing `From` implementation for `InnerG5`. The fix involved correcting the test logic to use the generated setter name (`_0`) and adding the missing `From` implementation in the manual test file.

Added Increment 4 to address this. -* [2025-04-24/Inc 1] Errors E0412/E0433 in `scalar_generic_tuple_manual.rs` likely stem from the manual test incorrectly trying to use types generated by the derive macro, violating the Proc Macro Workflow design rule. The fix involves modifying the manual test to use direct scalar construction. -* [2025-04-24/Inc 1] After applying changes to `scalar_generic_tuple_manual.rs` and `scalar_generic_tuple_only_test.rs`, the errors specific to `scalar_generic_tuple_manual.rs` are expected to be resolved. The remaining errors are in other test files. Increment 1 is considered complete. -* [2025-04-24/Inc 2] Errors E0061/E0599 in `multi_field_only_test.rs` were caused by a mismatch between the manual implementation (direct constructor) and the test logic/derived behavior (former builder) for the `MultiTuple` variant. The fix involved updating the manual implementation in `multi_field_manual.rs` to provide a former builder. Increment 2 is considered complete. -* [2025-04-24/Inc 3] Errors E0599 in `generics_independent_tuple_only_test.rs` were caused by a mismatch in setter names between the derived code and the test logic, and a missing `From` implementation for `InnerG5`. The fix involved correcting the test logic to use the generated setter name (`_0`) and adding the missing `From` implementation in the manual test file.

Identify discrepancies with the target consistent behavior rules. - * Detailed Plan Step 1: Read `former_meta/src/lib.rs` to understand the overall structure, features, and entry points for the different derive macros. - * Detailed Plan Step 2: Read `former_meta/src/derive_former.rs` and its submodules (`field_attrs.rs`, `field.rs`, `struct_attrs.rs`) to understand the main dispatch logic, attribute parsing, and helper structures used by the `Former` derive. - * Detailed Plan Step 3: Read `former_meta/src/derive_former/former_struct.rs` to understand how struct formers are generated (as a comparison point for consistency). - * Detailed Plan Step 4: Read `former_meta/src/derive_former/former_enum.rs` carefully. Map the existing code paths to different variant kinds (Unit, Tuple(1), Tuple(N), Struct(0), Struct(1), Struct(N)) and attribute combinations (`#[scalar]`, `#[subform_scalar]`, none). Pay close attention to how generics and bounds are handled. - * Detailed Plan Step 5: Document the findings from Step 4, specifically noting: - * How unit variants are handled (constructor generation). - * How single-field tuple variants are handled (default behavior, `#[scalar]`, `#[subform_scalar]`). Note the heuristic check for `inner_former_exists`. - * How multi-field tuple variants are handled (default behavior, `#[scalar]`, `#[subform_scalar]`). Note the error for the default case. - * How struct-like variants (0, 1, N fields) are handled (default behavior, `#[scalar]`, `#[subform_scalar]`). Note the implicit former generation logic. - * How generics and bounds are currently propagated in the enum logic (e.g., use of `generic_params::merge`, phantom data). - * Detailed Plan Step 6: Compare the documented current behavior (from Step 5) against the **Proposed Consistent Behavior Rules** defined during planning. Identify specific areas in `former_enum.rs` that need refactoring in subsequent increments (e.g., error handling for multi-field defaults, struct(0) handling, consistency of `#[scalar]` behavior). - * Detailed Plan Step 7: Record findings, identified discrepancies, and areas needing refactoring in the `## Notes & Insights` section of `plan.md`. - * Crucial Design Rules: [Structuring: Organize by Feature or Layer](#structuring-organize-by-feature-or-layer), [Comments and Documentation](#comments-and-documentation). - * **Rule Adherence Checkpoint:** Confirm strict adherence to `code/gen` instructions, Design Rules, and **especially Codestyle Rules (overriding existing style)** during the analysis and documentation phase. - * Verification Strategy: Manual review of the analysis findings against the codebase (`former_meta/src`) and the target rules. Confirm understanding of the current state and required changes. No code changes in this increment. -* ⏳ Increment 2: Refactor `former_enum.rs` for consistent unit/single-field scalar/subform behavior - * Goal: Modify the macro code to correctly generate direct constructors or subformer starters for unit and single-field variants according to the defined rules (considering `#[scalar]`, `#[subform_scalar]`, and default behavior). - * Detailed Plan Step 1: Locate the code block in `former_enum.rs` handling `syn::Fields::Unit`. Verify it correctly generates a direct constructor static method (`Enum::variant() -> Enum`). Ensure `#[scalar]` or `#[subform_scalar]` on unit variants are ignored or produce a reasonable error. - * Detailed Plan Step 2: Locate the code block handling `syn::Fields::Unnamed` with `fields.unnamed.len() == 1`. - * Detailed Plan Step 3: Remove the `inner_former_exists` heuristic check. - * Detailed Plan Step 4: Implement logic for `#[scalar]`: Ensure it *always* generates a direct constructor static method (`Enum::variant(InnerType) -> Enum`). - * Detailed Plan Step 5: Implement logic for `#[subform_scalar]`: Ensure it *always* generates a subformer starter static method (`Enum::variant() -> InnerFormer<...>`) and the corresponding `End` struct/impl. Add a check to error if the attribute is applied to a non-path inner type (e.g., `Variant( (i32) )`). Rely on the compiler for errors if `InnerFormer` doesn't exist. - * Detailed Plan Step 6: Implement logic for the **Default (No Attribute)** case: Ensure it *always* generates a subformer starter static method (`Enum::variant() -> InnerFormer<...>`) and the corresponding `End` struct/impl (as per the **Revised Rule**). Rely on the compiler for errors if `InnerFormer` doesn't exist. - * Detailed Plan Step 7: Apply the same logic (Steps 4-6) to single-field *struct* variants (`syn::Fields::Named` with `fields.named.len() == 1`). - * Detailed Plan Step 8: Ensure consistent handling of generics and bounds propagation in all generated code paths within this increment. - * Crucial Design Rules: [Code Style: Do Not Reformat Arbitrarily](#code-style-do-not-reformat-arbitrarily) (apply mandated style), [Visibility: Keep Implementation Details Private](#visibility-keep-implementation-details-private). - * **Rule Adherence Checkpoint:** Confirm strict adherence to `code/gen` instructions, Design Rules, and **especially Codestyle Rules (overriding existing style)** during refactoring. - * Verification Strategy: Compile checks (`cargo check --package former_meta`), review generated code snippets mentally or using `#[debug]` for specific test cases (e.g., `basic_*`, `scalar_generic_tuple_*` variant 1), ensure no regressions in related tests yet (though full testing is in later increments). -* ⚫ Increment 3: Refactor `former_enum.rs` for consistent multi-field/struct variant behavior - * Goal: Modify the macro code to generate implicit former builders for multi-field/struct variants *only* when `#[scalar]` is present. Generate compile-time errors for multi-field/struct variants without `#[scalar]`. Ensure struct(0) variants behave like multi-field. -* ⚫ Increment 4: Update tests for unit/single-field variants - * Goal: Review and update tests in `former/tests/inc/former_enum_tests/` related to unit and single-field variants (e.g., `unit_*`, `basic_*`, `scalar_generic_tuple_*`, `generics_shared_tuple_*`, `generics_independent_tuple_*`) to ensure they align with the refactored, consistent logic. Update corresponding `*_manual.rs` files. -* ⚫ Increment 5: Update tests for multi-field/struct variants & remove qqq comment - * Goal: Review and update tests related to multi-field/struct variants (e.g., `multi_field_*`, `enum_named_fields_*`, `generics_shared_struct_*`, `generics_independent_struct_*`). Ensure they test the implicit former builder generation with `#[scalar]` and potentially add tests for the error case without `#[scalar]`. Remove the misleading `qqq` comment from `scalar_generic_tuple_derive.rs`. Update corresponding `*_manual.rs` files. -* ⚫ Increment 6: Update documentation (`Readme.md`, `advanced.md`) - * Goal: Clearly document the consistent rules for how `#[derive(Former)]` handles different enum variants and the effects of `#[scalar]` and `#[subform_scalar]` attributes in the main `former` crate documentation. -* ⚫ Increment 7: Final verification - * Goal: Run the entire test suite for the `former` crate (`cargo test`) to ensure all tests pass and there are no regressions. +* ✅ Increment 1: Run Tests & Capture Output for `enum_named_fields_derive` + * Goal: Execute the test suite with only the `enum_named_fields_derive` test (and its manual counterpart) enabled within the `former_enum_tests` module to capture the specific compilation errors. + * Detailed Plan Step 1: Ensure `module/core/former/tests/inc/mod.rs` reflects the configuration provided by the user (only `basic_*` and `enum_named_fields_*` tests uncommented in `former_enum_tests`). + * Detailed Plan Step 2: Run the command `cargo test --package former --test former_enum_test`. + * Detailed Plan Step 3: Record the exact compilation errors related to `enum_named_fields_derive.rs` and `enum_named_fields_only_test.rs` in the `## Notes & Insights` section. + * Crucial Design Rules: N/A (Observation step). + * Verification Strategy: Confirm that the test command was executed and the relevant errors were captured accurately. +* ✅ Increment 2: Analyze `enum_named_fields_derive` Failure + * Goal: Analyze the captured errors and the macro-generated code for `EnumWithNamedFields` to understand why the test fails. + * Detailed Plan Step 1: Review the errors recorded in Increment 1 (E0599 missing methods). + * Detailed Plan Step 2: Add `#[debug]` to `EnumWithNamedFields` in `enum_named_fields_derive.rs`. + * Detailed Plan Step 3: Run `cargo check --package former` to view the generated code snippet.

Unit and single-field tuple handling mostly aligns with target rules. Multi-field tuple handling aligns. Error handling for invalid attribute combinations (e.g., `#[subform_scalar]` on multi-field) is missing. -* [2025-04-24/Inc 2] **Rule Adjustment:** Default behavior for Single-Field variants (Tuple or Struct) will now *always* generate a Subformer Starter, relying on the compiler to error if the inner type does not derive `Former`. This removes the unreliable heuristic check. \ No newline at end of file +* [2025-04-24/New Plan] Adopted iterative approach: Fix one failing enum test group at a time. Start with `enum_named_fields_derive`. +* [2025-04-24/Inc 1] Ran `cargo test --package former --test former_enum_test` with only `basic_*` and `enum_named_fields_*` tests enabled. Captured 3 E0599 errors in `enum_named_fields_only_test.rs` indicating missing static methods (`variant_zero`, `variant_one`, `variant_two`) for struct-like variants. Also observed 5 expected warnings about unused code in `former_meta`. +* [2025-04-24/Inc 2] Analysis of `enum_named_fields_derive` failure: Confirmed missing implementation for `syn::Fields::Named`. Test expectations need adjustment later. Root cause is missing logic. +* [2025-04-24/Correction] **Crucial:** Realized previous plan incorrectly made `#[scalar]` generate an implicit former for struct-like variants. **Revised Rule:** `#[scalar]` *always* generates a direct constructor (taking all fields as args) for *any* non-unit variant (single/multi field, tuple/struct). Default behavior for multi-field/struct variants is now an error. Implicit formers are *not* generated for variants. Plan revised accordingly. +* [2025-04-24/Inc 3] Implemented error handling for struct-like variants without `#[scalar]` or with `#[subform_scalar]`. Removed unused helper functions. Verification confirmed expected compile errors are now generated for `enum_named_fields_derive.rs` as it lacks `#[scalar]`. +* [2025-04-24/Inc 4] Implemented direct constructor generation logic for struct-like variants with `#[scalar]`. +* [2025-04-24/Inc 5] Modified `enum_named_fields_derive.rs` to add `#[scalar]` and adjusted `enum_named_fields_only_test.rs` to use direct constructors. Tests for this group now pass. \ No newline at end of file diff --git a/module/core/former/src/lib.rs b/module/core/former/src/lib.rs index e6424721ad..453441c315 100644 --- a/module/core/former/src/lib.rs +++ b/module/core/former/src/lib.rs @@ -3,6 +3,7 @@ #![ doc( html_favicon_url = "https://raw.githubusercontent.com/Wandalen/wTools/alpha/asset/img/logo_v3_trans_square_icon_small_v2.ico" ) ] #![ doc( html_root_url = "https://docs.rs/former/latest/former/" ) ] #![ doc = include_str!( concat!( env!( "CARGO_MANIFEST_DIR" ), "/", "Readme.md" ) ) ] +// qqq : uncomment it // xxx : introduce body( struct/enum ) attribute `standalone_constructors` which create stand-alone, top-level constructors for struct/enum. for struct it's always single function, for enum it's as many functions as enum has vartianys. if there is no `arg_for_constructor` then constructors expect exaclty zero arguments. start from implementations without respect of attribute attribute `arg_for_constructor`. by default `standalone_constructors` is false // xxx : introduce field attribute to mark an attribute `arg_for_constructor` as an argument which should be used in constructing functions ( either standalone consturcting function or associated with struct ). in case of enums attribute `arg_for_constructor` is attachable only to fields of variant and attempt to attach attribute `arg_for_constructor` to variant must throw understandable error. name standalone constructor of struct the same way struct named, but snake case and for enums the same name variant is named, but snake case. by default it's false. diff --git a/module/core/former/tests/inc/former_enum_tests/enum_named_fields_derive.rs b/module/core/former/tests/inc/former_enum_tests/enum_named_fields_derive.rs index b00c849d63..2b2883c6c2 100644 --- a/module/core/former/tests/inc/former_enum_tests/enum_named_fields_derive.rs +++ b/module/core/former/tests/inc/former_enum_tests/enum_named_fields_derive.rs @@ -1,32 +1,47 @@ +// File: module/core/former/tests/inc/former_enum_tests/enum_named_fields_derive.rs use super::*;

This isolates the most complex part of the enum derivation logic. +* **[Date/Increment 1] Requirement:** All file splitting operations (Increments 2 and 4) must maintain semantic equivalence with the original code. The primary verification for this will be running `cargo test` after each split. \ No newline at end of file diff --git a/module/core/former_meta/src/derive_former/field.rs b/module/core/former_meta/src/derive_former/field.rs index dafc324500..c58aa02faa 100644 --- a/module/core/former_meta/src/derive_former/field.rs +++ b/module/core/former_meta/src/derive_former/field.rs @@ -180,8 +180,11 @@ impl< 'a > FormerField< 'a > let ident = self.ident; let ty = self.ty; + + // <<< Reverted: Use AttributePropertyOptionalSyn and ref_internal() >>> let default : Option< &syn::Expr > = self.attrs.config.as_ref() .and_then( | attr | attr.default.ref_internal() ); + // <<< End Revert >>> let tokens = if self.is_optional { @@ -558,12 +561,13 @@ field : {field_ident}", field_ident }; // example : `former::VectorDefinition` - let subformer_definition = &attr.definition; - let subformer_definition = if subformer_definition.is_some() + // <<< Reverted: Use ref_internal() on AttributePropertyOptionalSyn >>> + let subformer_definition_type = attr.definition.ref_internal(); + let subformer_definition = if let Some( def_type ) = subformer_definition_type { qt! { - #subformer_definition + #def_type // <<< Use the parsed syn::Type directly < #( #params, )* Self, @@ -583,6 +587,7 @@ field : {field_ident}", } // < Vec< String > as former::EntityToDefinition< Self, Self, Struct1SubformCollectionVec1End > >::Definition }; + // <<< End Revert >>> let doc = format!

* Detailed Plan Step 1: **Fix E0599 Errors:** Modify the calls to `handle_unit_variant`, `handle_tuple_zero_variant`, `handle_struct_zero_variant`, and the *future* call to `handle_struct_non_zero_variant` within `former_for_enum` in `former_enum.rs`. Change the last argument from `merged_where_clause.map(|wc| &wc.predicates)` back to `merged_where_clause`. - * Detailed Plan Step 2: **Update Handler Signatures:** Modify the function signatures in `unit.rs`, `tuple_zero.rs`, and `struct_zero.rs` to accept `merged_where_clause : Option< &'a syn::WhereClause >` instead of `Option< &'a syn::punctuated::Punctuated<...> >`. Adjust the internal logic of these handlers if they were using the predicates directly (they likely weren't, as the error occurred during the call). - * Detailed Plan Step 3: **Create File:** Create `module/core/former_meta/src/derive_former/former_enum/struct_non_zero.rs`. - * Detailed Plan Step 4: **Add Module Declaration:** Add `mod struct_non_zero;` and `use struct_non_zero::handle_struct_non_zero_variant;` to `module/core/former_meta/src/derive_former/former_enum/mod.rs`. - * Detailed Plan Step 5: **Define Function:** Define the function signature for `handle_struct_non_zero_variant` in `struct_non_zero.rs`, ensuring it accepts all necessary parameters (including `merged_where_clause : Option< &'a syn::WhereClause >`) and has the correct visibility (`pub(super)` likely). - * Detailed Plan Step 6: **Move Logic:** Cut the code block corresponding to the `Fields::Named( fields )` match arm (where `fields.named.len() > 0`) from `former_for_enum` in `former_enum.rs` and paste it into the body of `handle_struct_non_zero_variant` in `struct_non_zero.rs`. - * Detailed Plan Step 7: **Adjust Paths/Visibility:** Correct any import paths or visibility issues within the moved code block. Ensure it uses the passed parameters correctly. - * Detailed Plan Step 8: **Update Caller:** In `former_for_enum` (in `former_enum.rs`), replace the moved code block with a call to `handle_struct_non_zero_variant`, passing the necessary arguments. - * Detailed Plan Step 9: **Apply Codestyle:** Strictly apply codestyle rules (spacing, newlines, indentation) to `struct_non_zero.rs` and the modified `former_enum.rs`. - * Crucial Design Rules: [Structuring: Organize by Feature or Layer](code/rules/design.md#structuring-organize-by-feature-or-layer), [Structuring: Add Module Declaration Before Content](code/rules/design.md#structuring-add-module-declaration-before-content), [Visibility: Keep Implementation Details Private](code/rules/design.md#visibility-keep-implementation-details-private). - * Verification Strategy: Run `cargo check --package former_meta` after fixing E0599 errors (Step 1 & 2). Analyze output. Run `cargo check --package former_meta` after moving the code (Step 3-8). Analyze output. Run `cargo test --package former` to ensure semantic equivalence after the refactoring is complete. **Analyze logs critically.** -* ⚫ Increment 7: Update main match statement to use new former_enum -* ⚫ Increment 8: Verify refactoring with tests +## Increments ## Notes & Insights diff --git a/module/core/former/tests/inc/former_enum_tests/basic_derive.rs b/module/core/former/tests/inc/former_enum_tests/basic_derive.rs index 5583a9723d..cc99f1bace 100644 --- a/module/core/former/tests/inc/former_enum_tests/basic_derive.rs +++ b/module/core/former/tests/inc/former_enum_tests/basic_derive.rs @@ -9,13 +9,58 @@ pub struct Break { pub condition : bool } pub struct Run { pub command : String } // Derive Former on the simplified enum - This should generate static methods -#[derive(Debug, Clone, PartialEq, former::Former)] -// #[debug] +#[ derive( Debug, Clone, PartialEq ) ] +// #[ derive( Debug, Clone, PartialEq, former::Former ) ] +// #[ debug ] enum FunctionStep { Break( Break ), Run( Run ), } +// xxx : generated code for debugging + + + #[automatically_derived] impl < > FunctionStep < > where + { + #[inline(always)] fn r#break() -> BreakFormer < BreakFormerDefinition < () + FunctionStep < > , FunctionStepBreakEnd < > > > + { + BreakFormer :: + begin(None, None, FunctionStepBreakEnd :: < > :: default()) + } #[inline(always)] fn run() -> RunFormer < RunFormerDefinition < () + FunctionStep < > , FunctionStepRunEnd < > > > + { RunFormer :: begin(None, None, FunctionStepRunEnd :: < > :: default()) } + } #[derive(Default, Debug)] struct FunctionStepBreakEnd < > where + { _phantom : :: core :: marker :: PhantomData < () > , } + #[automatically_derived] impl < > former :: FormingEnd < + BreakFormerDefinitionTypes < () FunctionStep < > > > for FunctionStepBreakEnd + < > where + { + #[inline(always)] fn + call(& self, sub_storage : BreakFormerStorage < > , _context : Option < () + >) -> FunctionStep < > + { + let data = former :: StoragePreform :: preform(sub_storage);

Initiating Stuck Resolution Process. -* **[2025-04-29] Hypotheses for Increment 6:** - * Hypothesis 1: The generated `Storage` struct or its implementations contain a brace mismatch or syntax error. - * Hypothesis 2: The generated `DefinitionTypes` struct or its implementations contain a brace mismatch or syntax error. - * Hypothesis 3: The generated `Definition` struct or its implementations contain a brace mismatch or syntax error. - * Hypothesis 4: The generated `Former` struct contains a brace mismatch or syntax error. - * Hypothesis 5: The issue arises from the combination or interaction of the individually generated components, not the components themselves. -* **[2025-04-29/Increment 6] Hypothesis Test:** Hypothesis 1: The generated `Storage` struct or its implementations contain a brace mismatch or syntax error. - **Result:** Rejected - **Reasoning:** Manual code review of the `quote!` blocks generating the `Storage` struct and its `impl` blocks (`storage_def`, `storage_default_impl`, `storage_trait_impl`, `storage_preform_impl`) in `struct_non_zero.rs` did not reveal any obvious brace mismatches or syntax errors violating codestyle rules. -* **[2025-04-29/Increment 6] Hypothesis Test:** Hypothesis 2: The generated `DefinitionTypes` struct or its implementations contain a brace mismatch or syntax error. - **Result:** Rejected - **Reasoning:** Manual code review of the `quote!` blocks generating the `DefinitionTypes` struct and its `impl` blocks (`def_types_struct`, `def_types_default_impl`, `def_types_former_impl`, `def_types_mutator_impl`) in `struct_non_zero.rs` did not reveal any obvious brace mismatches or syntax errors violating codestyle rules. -* **[2025-04-29/Increment 6] Hypothesis Test:** Hypothesis 3: The generated `Definition` struct or its implementations contain a brace mismatch or syntax error. - **Result:** Rejected - **Reasoning:** Manual code review of the `quote!` blocks generating the `Definition` struct and its `impl` blocks (`def_struct`, `def_default_impl`, `def_former_impl`) in `struct_non_zero.rs` did not reveal any obvious brace mismatches or syntax errors violating codestyle rules. -* **[2025-04-29/Increment 6] Hypothesis Test:** Hypothesis 4: The generated `Former` struct contains a brace mismatch or syntax error. - **Result:** Rejected - **Reasoning:** Manual code review of the `quote!` block generating the `Former` struct definition (`former_struct_def`) in `struct_non_zero.rs` did not reveal any obvious brace mismatches or syntax errors violating codestyle rules. -* **[2024-04-30/Increment 6] Fix:** Resolved E0599 compilation errors by changing how `merged_where_clause` is passed to handler functions (passing `Option<&WhereClause>` instead of `Option<&Punctuated<...>>`). -* **[2024-04-30/Increment 1] Insight:** Initial test failures (E0599) in `former_enum_tests::basic_derive` were caused by the `#[derive(former::Former)]` attribute being commented out in the test setup file (`basic_derive.rs`). Uncommenting it resolved the failures. The test code in `basic_only_test.rs` correctly expected the default former behavior (returning formers), not the scalar behavior. -* **[2024-04-30/Increment 2] Insight:** Attempting to add `mod former_enum;` to a non-existent `mod.rs` file and then adding a duplicate declaration in `derive_former.rs` caused compilation errors (E0761, E0428). The `former_enum` module is correctly defined by `former_enum.rs`. Removing the duplicate declaration and the redundant `mod.rs` file resolved these errors. -* **Insight:** Debugging revealed syntax errors in generated code related to comma placement in generic argument lists (e.g., `< () Enum<> >` vs `< (), Enum<> >`) and function signatures (trailing comma in `call` parameters). Careful construction of generic lists in `quote!` is crucial, especially when combining potentially empty enum generics with other parameters.

Uncommenting it resolved the failures. The test code in `basic_only_test.rs` correctly expected the default former behavior (returning formers), not the scalar behavior. -* **[2024-04-30/Increment 2] Insight:** Attempting to add `mod former_enum;` to a non-existent `mod.rs` file and then adding a duplicate declaration in `derive_former.rs` caused compilation errors (E0761, E0428).

Start with `enum_named_fields_derive`. -* [2025-04-24/Inc 1] Ran `cargo test --package former --test former_enum_test` with only `basic_*` and `enum_named_fields_*` tests enabled. Captured 3 E0599 errors in `enum_named_fields_only_test.rs` indicating missing static methods (`variant_zero`, `variant_one`, `variant_two`) for struct-like variants. Also observed 5 expected warnings about unused code in `former_meta`. -* [2025-04-24/Inc 2] Analysis of `enum_named_fields_derive` failure: Confirmed missing implementation for `syn::Fields::Named`. Test expectations need adjustment later. Root cause is missing logic. -* [2025-04-24/Correction] **Crucial:** Realized previous plan incorrectly made `#[scalar]` generate an implicit former for struct-like variants. **Revised Rule:** `#[scalar]` *always* generates a direct constructor (taking all fields as args) for *any* non-unit variant (single/multi field, tuple/struct). Default behavior for multi-field/struct variants is now an error. Implicit formers are *not* generated for variants. Plan revised accordingly. -* [2025-04-24/Inc 3] Implemented error handling for struct-like variants without `#[scalar]` or with `#[subform_scalar]`. Removed unused helper functions. Verification confirmed expected compile errors are now generated for `enum_named_fields_derive.rs` as it lacks `#[scalar]`. -* [2025-04-24/Inc 4] Implemented direct constructor generation logic for struct-like variants with `#[scalar]`. -* [2025-04-24/Inc 5] Modified `enum_named_fields_derive.rs` to add `#[scalar]` and adjusted `enum_named_fields_only_test.rs` to use direct constructors. Tests for this group now pass. -* [2025-04-24/Correction 2] **Crucial:** User clarified that `#[subform_scalar]` *should* work on single-field struct variants and multi-field varians as swell, and the default for single-field struct variants and multi-field must be subforming (like single-field tuple). The default for zero-field struct variants should be an error. Plan revised again. -* **[2024-04-25/Plan Update]** Revised detailed steps for Increment 6 to align with the final rules provided by the user. Added placeholder increments (10-24) to address remaining test files. Renumbered final increments. -* **[2024-04-25/Inc 6 Correction]** Fixed regressions related to unused variables and scope issues in test files. -* **[2024-04-25/Inc 6 Correction 2]** Fixed regressions related to syntax errors (extra commas) and logic errors (`FormingEnd::call`) in generated code for implicit formers. -* **[2024-04-25/Inc 6 Decomposition]** Decomposed Step 8 (Multi-Field Struct Variant - Subformer Case) into smaller sub-steps (8a-8i) to isolate and verify the generation of each implicit former component. Updated plan accordingly. Renumbered subsequent increments. -* **[2024-04-25/Inc 6 Hypothesis]** Confirmed hypotheses for implicit former generation for multi-field struct variants. Key points: generate dedicated former ecosystem for the variant, storage holds `Option` for all variant fields, `preform` returns tuple, former has setters for all variant fields, `End::call` uses preformed tuple to construct variant. Generics handling (H6) and `End::call` logic (H8) require careful implementation. -* **[2024-04-25/Inc 6 Plan Revision]** Further decomposed Increment 6. Will now implement logic for each variant type incrementally (Unit, Tuple(0), Tuple(1), Tuple(N), Struct(0), Struct(1), Struct(N)-Scalar). The complex Struct(N)-Subformer case is broken into multiple increments (12-21) based on verified hypotheses. -* **[2024-04-25/Plan Update 2]** Added explicit test enabling steps to increments 6-11, 23-26. Renumbered final increments. -* **[2024-04-26/Plan Revision 3]** Focused plan on fixing `generics_shared_struct_derive.rs` failure by implementing the multi-field struct subformer logic (Increments 1-10). Added final verification increment (11). Preserved previous notes. -* **[2024-04-26/Inc 1]** Completed implementation of storage struct definition and default impl for multi-field struct variant subformer case. Compile check passed. -* **[2024-04-26/Inc 2]** Completed implementation of `Storage` and `StoragePreform` traits for the implicit storage struct. Compile check passed. -* **[2024-04-26/Inc 3]** Completed implementation of `DefinitionTypes` struct and its trait impls (`Default`, `FormerDefinitionTypes`, `FormerMutator`) for the implicit former. Compile check passed. -* **[2024-04-26/Inc 4]** Completed implementation of `Definition` struct and its trait impls (`Default`, `FormerDefinition`) for the implicit former. Compile check passed (warnings noted as expected). \ No newline at end of file From ea57ef21cbd2790408a98b86ed241d7ec4009534 Mon Sep 17 00:00:00 2001 From: wandalen Date: Wed, 30 Apr 2025 07:41:33

+ +The `component_model` crate provides a powerful derive macro, `#[ derive( Former ) ]`, that automatically implements the **Builder pattern** for your Rust structs and enums. + +Its primary goal is to **simplify the construction of complex objects**, especially those with numerous fields, optional values, default settings, collections, or nested structures, making your initialization code more readable and maintainable. + +## Why Use `Former`? + +Compared to manually implementing the Builder pattern or using other builder crates, `component_model` offers several advantages: + +* **Reduced Boilerplate:** `#[ derive( Former ) ]` automatically generates the builder struct, storage, and setters, saving you significant repetitive coding effort. +* **Fluent & Readable API:** Construct objects step-by-step using clear, chainable methods (`.field_name( value )`). +* **Effortless Defaults & Optionals:** Fields automatically use their `Default` implementation if not set. `Option< T >` fields are handled seamlessly – you only set them if you have a `Some( value )`. Custom defaults can be specified easily with `#[ component_model( default = ... ) ]`. +* **Powerful Collection & Nested Struct Handling:** `component_model` truly shines with its **subcomponent_model** system. Easily build `Vec`, `HashMap`, `HashSet`, and other collections element-by-element, or configure nested structs using their own dedicated component_models within the parent's builder chain.

Default: `true`. + +## Core Concepts Deep Dive + +Understanding the components generated by `#[ derive( Former ) ]` helps in customizing the builder pattern effectively. + +### Storage (`...FormerStorage`) + +When you derive `Former` for a struct like `MyStruct`, a corresponding storage struct, typically named `MyStructFormerStorage`, is generated internally. + +* **Purpose:** This storage struct acts as a temporary container holding the intermediate state of the object during its construction via the component_model. +* **Fields:** It contains fields corresponding to the original struct's fields, but wrapped in `Option`. For example, a field `my_field : i32` in `MyStruct` becomes `pub my_field : Option< i32 >` in `MyStructFormerStorage`. This allows the component_model to track which fields have been explicitly set. Optional fields in the original struct (e.g., `my_option : Option< String >`) remain `Option< String >` in the storage. +* **Storage-Only Fields:** If you use the `#[ storage_fields( ... ) ]` attribute on the struct, those additional fields are *only* present in the storage struct, not in the final formed struct. This is useful for temporary calculations or state needed during the building process. +* **Decoupling:** The storage struct decouples the configuration steps (calling setters) from the final object instantiation (`.form()` or `.end()`). You can call setters in any order. +* **Finalization:** When `.form()` or `.end()` is called, the `StoragePreform::preform` method is invoked on the storage struct. This method consumes the storage, unwraps the `Option`s for required fields (panicking or using defaults if not set), handles optional fields appropriately, and constructs the final struct instance (`MyStruct`). + +The `...Former` struct itself holds an instance of this `...FormerStorage` struct internally to manage the building process. + +### Definitions (`...Definition`, `...DefinitionTypes`) + +Alongside the `Former` and `Storage` structs, the derive macro also generates two definition structs: `...FormerDefinitionTypes` and `...FormerDefinition`. + +* **`...FormerDefinitionTypes`:** + * **Purpose:** Defines the core *types* involved in the formation process for a specific entity. + * **Associated Types:** + * `Storage`: Specifies the storage struct used (e.g., `MyStructFormerStorage`). + * `Formed`: Specifies the type that is ultimately produced by the `.form()` or `.end()` methods. By default, this is the original struct (e.g., `MyStruct`), but it can be changed by custom `FormingEnd` implementations. + * `Context`: Specifies the type of contextual information passed down during subforming (if the component_model is used as a subcomponent_model). Defaults to `()`. + * **Traits:** Implements `component_model_types::FormerDefinitionTypes` and `component_model_types::FormerMutator`. + +* **`...FormerDefinition`:** + * **Purpose:** Extends `...FormerDefinitionTypes` by adding the *end condition* logic. It fully defines how a component_model behaves. + * **Associated Types:** Inherits `Storage`, `Formed`, `Context`, and `Types` (which points back to the `...FormerDefinitionTypes` struct) from the `component_model_types::FormerDefinition` trait. + * **`End` Associated Type:** Specifies the type that implements the `component_model_types::FormingEnd` trait, defining what happens when `.form()` or `.end()` is called. This defaults to `component_model_types::ReturnPreformed` (which calls `StoragePreform::preform` on the storage) but can be customized. + * **Traits:** Implements `component_model_types::FormerDefinition`. + +* **Role in Generics:** The `Definition` generic parameter on the `...Former` struct (e.g., `MyStructFormer< Definition = ... >`) allows customizing the entire forming behavior by providing a different `FormerDefinition` implementation. This enables advanced scenarios like changing the formed type or altering the end-of-forming logic. + +In most basic use cases, you don't interact with these definition structs directly, but they underpin the flexibility and customization capabilities of the `component_model` crate, especially when dealing with subcomponent_models and custom end logic. + +### Context + +The `Context` is an optional piece of data associated with a `Former`. It plays a crucial role primarily when a `Former` is used as a **subcomponent_model** (i.e., when building a nested struct or collection entries). + +* **Purpose:** To pass information or state *down* from a parent component_model to its child subcomponent_model during the building process. +* **Default:** For a top-level component_model (one created directly via `MyStruct::component_model()`), the context type defaults to `()` (the unit type), and the context value is `None`. +* **Subforming:** When a subcomponent_model is initiated (e.g., by calling `.my_subform_field()` on a parent component_model), the parent component_model typically passes *itself* as the context to the subcomponent_model. +* **`FormingEnd` Interaction:** The `FormingEnd::call` method receives the context (`Option< Context >`) as its second argument. When a subcomponent_model finishes (via `.end()`), its `FormingEnd` implementation usually receives the parent component_model (`Some( parent_component_model )`) as the context. This allows the `End` logic to: + 1. Retrieve the formed value from the subcomponent_model's storage. + 2. Modify the parent component_model's storage (e.g., insert the formed value into the parent's collection or field). + 3. Return the modified parent component_model to continue the building chain. +* **Customization:** While the default context is `()` or the parent component_model, you can define custom component_models and `FormingEnd` implementations that use different context types to pass arbitrary data relevant to the specific building logic. + +In essence, the context provides the mechanism for subcomponent_models to communicate back and integrate their results into their parent component_model upon completion. + +### End Condition (`FormingEnd`, `ReturnStorage`, `ReturnPreformed`, Closures) + +The `End` condition determines what happens when the forming process is finalized by calling `.form()` or `.end()` on a `Former`. It's defined by the `End` associated type within the `FormerDefinition` and must implement the `component_model_types::FormingEnd` trait. + +* **`FormingEnd` Trait:** + * Defines a single method: `call( &self, storage : Definition::Storage, context : Option< Definition::Context > ) -> Definition::Formed`. + * This method consumes the `storage` and optional `context` and produces the final `Formed` type. + +* **Default End Conditions (Provided by `component_model_types`):** + * **`ReturnPreformed`:** This is the default `End` type for component_models generated by `#[ derive( Former ) ]`. Its `call` implementation invokes `StoragePreform::preform` on the storage, effectively unwrapping `Option`s, applying defaults, and constructing the final struct instance. It ignores the context. The `Formed` type is the original struct type. + * **`ReturnStorage`:** A simpler `End` type often used for collection component_models. Its `call` implementation simply returns the storage itself *without* calling `preform`. The `Formed` type is the same as the `Storage` type (e.g., `Vec< T >`, `HashMap< K, V >`). It also ignores the context. + * **`NoEnd`:** A placeholder that panics if `call` is invoked. Useful in generic contexts where an `End` type is required syntactically but never actually used. + +* **Subcomponent_model End Conditions (Generated by `#[ derive( Former ) ]`):** + * When you use subform attributes (`#[ subform_scalar ]`, `#[ subform_collection ]`, `#[ subform_entry ]`), the derive macro generates specialized internal `End` structs (e.g., `ParentFormerSubformScalarChildEnd`). + * The `call` implementation for these generated `End` structs typically: + 1. Takes the subcomponent_model's `storage` and the parent component_model as `context`. + 2. Calls `StoragePreform::preform` on the subcomponent_model's storage to get the formed value (e.g., the `Child` instance or the `Vec< Child >`). + 3. Assigns this formed value to the appropriate field in the parent component_model's storage (retrieved from the `context`). + 4. Returns the modified parent component_model (`Formed` type is the parent component_model). + +* **Custom End Conditions (Closures & Structs):** + * You can provide a custom closure or a struct implementing `FormingEnd` when manually constructing a component_model using methods like `Former::begin`, `Former::new`, or their `_coercing` variants. + * This allows you to define arbitrary logic for the finalization step, such as: + * Performing complex validation on the storage before forming. + * Transforming the storage into a different `Formed` type. + * Integrating the result into a custom context. + * `component_model_types::FormingEndClosure` is a helper to easily wrap a closure for use as an `End` type. + +The `End` condition provides the final hook for controlling the transformation from the intermediate storage state to the desired final output of the forming process. + +### Mutators (`FormerMutator`, `#[mutator(custom)]`) + +The `FormerMutator` trait provides an optional hook to modify the `Storage` and `Context` *just before* the `FormingEnd::call` method is invoked during the finalization step (`.form()` or `.end()`). + +* **Purpose:** To perform last-minute adjustments, calculations, or conditional logic based on the accumulated state in the storage *before* the final transformation into the `Formed` type occurs. This is particularly useful for: + * Setting derived fields based on other fields set during the building process. + * Applying complex validation logic that depends on multiple fields. + * Making use of `#[ storage_fields( ... ) ]` to compute final values for the actual struct fields. + +* **`FormerMutator` Trait:** + * Associated with the `...FormerDefinitionTypes` struct. + * Defines one method: `form_mutation( storage: &mut Self::Storage, context: &mut Option< Self::Context > )`. + * This method receives *mutable* references, allowing direct modification of the storage and context. + +* **Default Behavior:** By default, `#[ derive( Former ) ]` generates an empty `impl FormerMutator` for the `...FormerDefinitionTypes`. This means no mutation occurs unless customized. + +* **Customization (`#[ mutator( custom ) ]`):** + * Applying `#[ mutator( custom ) ]` to the struct tells the derive macro *not* to generate the default empty implementation. + * You must then provide your own `impl FormerMutator for YourStructFormerDefinitionTypes< ... > { ... }` block, implementing the `form_mutation` method with your custom logic. + +* **Execution Order:** `FormerMutator::form_mutation` runs *after* the user calls `.form()` or `.end()` but *before* `FormingEnd::call` is executed. + +* **vs. `FormingEnd`:** While `FormingEnd` defines the *final transformation* from storage to the formed type, `FormerMutator` allows *intermediate modification* of the storage/context just prior to that final step. It's useful when the logic depends on the builder's state but shouldn't be part of the final type conversion itself. + +[See Example: Mutator and Storage Fields](https://github.com/Wandalen/wTools/blob/master/module/core/component_model/examples/component_model_custom_mutator.rs) + +## Subcomponent_model Types In Detail + +Subcomponent_models are a key feature of the `component_model` crate, enabling the construction of nested data structures and collections in a fluent manner. Different attributes control how subcomponent_models are generated and behave. + +### `#[ subform_scalar ]` - Building Nested Structs + +Use the `#[ subform_scalar ]` attribute on a field whose type *also* derives `Former`. This generates a setter method that returns the dedicated `Former` for that field's type, allowing you to configure the nested struct within the parent's builder chain. + +* **Attribute:** `#[ subform_scalar ]` (applied to the field in the parent struct) +* **Requirement:** The field's type (e.g., `Child` in `parent_field: Child`) must derive `Former`. +* **Generated Setter:** By default, a method with the same name as the field (e.g., `.child()`) is generated on the parent's component_model (`ParentFormer`). This method returns the child's component_model (`ChildFormer`). +* **Usage:** + ```rust + parent_component_model + .child() // Returns ChildFormer< ParentFormer, ... > + .child_field1(...) + .child_field2(...) + .end() // Finalizes Child, returns control to ParentFormer + .form() // Finalizes Parent + ``` +* **`End` Condition:** The derive macro automatically generates a specialized `End` struct (e.g., `ParentFormerSubformScalarChildEnd`) for the subcomponent_model. When `.end()` is called on the subcomponent_model (`ChildFormer`), this `End` struct's `call` method takes the finalized `Child` storage, preforms it into a `Child` instance, assigns it to the `child` field in the parent's storage (passed via context), and returns the parent component_model. +* **Customization:** + * `#[ subform_scalar( name = new_setter_name ) ]`: Renames the generated setter method (e.g., `.child_alt()` instead of `.child()`). + * `#[ subform_scalar( setter = false ) ]`: Disables the generation of the user-facing setter method (`.child()`). However, it still generates the internal helper method (e.g., `._child_subform_scalar()`) and the `End` struct, allowing you to create custom setters with different arguments while reusing the core subforming logic. + +**Example:** + +```rust +# #[ cfg( not( all( feature = "enabled", feature = "derive_component_model", any( feature = "use_alloc",not( feature = "no_std" ) ) ) ) ) ] +# fn main() {} +# #[ cfg( all( feature = "enabled", feature = "derive_component_model", any( feature = "use_alloc",not( feature = "no_std" ) ) ) ) ] +# fn main() +# { + use component_model::Former; + + #[ derive( Debug, Default, PartialEq, Former ) ] + pub struct Address + { + street : String, + city : String, + } + + #[ derive( Debug, Default, PartialEq, Former ) ] + pub struct User + { + name : String, + #[ subform_scalar ] // Use subcomponent_model for the 'address' field + address : Address, + } + + let user = User::component_model() + .name( "Alice".to_string() ) + .address() // Returns AddressFormer< UserFormer, ... > + .street( "123 Main St".to_string() ) + .city( "Anytown".to_string() ) + .end() // Finalizes Address, returns UserFormer + .form(); // Finalizes User + + assert_eq!( user.name, "Alice" ); + assert_eq!( user.address.street, "123 Main St" ); + assert_eq!( user.address.city, "Anytown" ); +# } +``` +[See full example code](https://github.com/Wandalen/wTools/blob/master/module/core/component_model/examples/component_model_custom_subform_scalar.rs) + +### `#[ subform_collection ]` - Building Collections Fluently + +Use the `#[ subform_collection ]` attribute on fields that represent collections like `Vec< E >`, `HashMap< K, V >`, `HashSet< K >`, etc. This generates a setter method that returns a specialized **collection component_model** tailored to the specific collection type, allowing you to add multiple elements fluently. + +* **Attribute:** `#[ subform_collection ]` (applied to the collection field) +* **Requirement:** The field type must be a collection type for which `component_model` has built-in support (e.g., `Vec`, `HashMap`, `HashSet`, `BTreeMap`, `BTreeSet`, `LinkedList`, `BinaryHeap`) or a custom type that implements the necessary `component_model_types::Collection` traits. +* **Generated Setter:** By default, a method with the same name as the field (e.g., `.entries()`) is generated. This method returns a `component_model_types::CollectionFormer` instance specialized for the field's collection type (e.g., `VectorFormer`, `HashMapFormer`). +* **Usage:** + ```rust + parent_component_model + .entries() // Returns e.g., VectorFormer< String, ParentFormer, ... > + .add( "item1".to_string() ) // Use collection-specific methods + .add( "item2".to_string() ) + .end() // Finalizes the collection, returns control to ParentFormer + .form() // Finalizes Parent + ``` +* **Collection Methods:** The returned collection component_model provides methods like `.add( entry )` and `.replace( iterator )`. The exact type of `entry` depends on the collection (`E` for `Vec`/`HashSet`, `( K, V )` for `HashMap`). +* **`End` Condition:** Similar to `subform_scalar`, the derive macro generates a specialized `End` struct (e.g., `ParentSubformCollectionEntriesEnd`). Its `call` method takes the subcomponent_model's storage (the collection being built), assigns it to the corresponding field in the parent component_model's storage, and returns the parent component_model. +* **Customization:** + * `#[ subform_collection( name = new_setter_name ) ]`: Renames the generated setter method. + * `#[ subform_collection( setter = false ) ]`: Disables the user-facing setter, but still generates the internal helper (`._entries_subform_collection()`) and `End` struct for custom setter implementation. + * `#[ subform_collection( definition = MyCollectionDefinition ) ]`: Specifies a custom `FormerDefinition` to use for the collection, overriding the default behavior (useful for custom collection types or specialized logic). + +**Example (Vec):** + +```rust +# #[ cfg( not( all( feature = "enabled", feature = "derive_component_model", any( feature = "use_alloc", not( feature = "no_std" ) ) ) ) ) ] +# fn main() {} +# #[ cfg( all( feature = "enabled", feature = "derive_component_model", any( feature = "use_alloc", not( feature = "no_std" ) ) ) ) ] +# fn main() +# { + use component_model::Former; + use std::collections::VecDeque; // Example using VecDeque + + #[ derive( Debug, PartialEq, Former ) ] + pub struct DataPacket + { + id : u32, + #[ subform_collection ] // Uses default VectorDefinition for Vec + // #[ subform_collection( definition = component_model::VecDequeDefinition ) ] // Example for VecDeque + payload : Vec< u8 >, + // payload : VecDeque< u8 >, // Alternative + } + + let packet = DataPacket::component_model() + .id( 101 ) + .payload() // Returns VectorFormer< u8, ... > + .add( 0xDE ) + .add( 0xAD ) + .add( 0xBE ) + .add( 0xEF ) + .end() + .form(); + + assert_eq!( packet.id, 101 ); + assert_eq!( packet.payload, vec![ 0xDE, 0xAD, 0xBE, 0xEF ] ); +# } +``` +[See Vec example](https://github.com/Wandalen/wTools/blob/master/module/core/component_model/examples/component_model_collection_vector.rs) | [See HashMap example](https://github.com/Wandalen/wTools/blob/master/module/core/component_model/examples/component_model_collection_hashmap.rs) | [See Custom Collection example](https://github.com/Wandalen/wTools/blob/master/module/core/component_model/examples/component_model_custom_collection.rs) + +### `#[ subform_entry ]` - Building Collection Entries Individually + +Use the `#[ subform_entry ]` attribute on collection fields (like `Vec< Child >` or `HashMap< String, Child >`) where each *entry* of the collection should be built using its own dedicated `Former`.

This is typically needed for integrating non-standard collections or implementing highly specialized finalization logic. + +* **Motivation:** + * Integrating custom collection types not supported by default. + * Changing the final `Formed` type returned by `.form()`/`.end()`. + * Implementing complex validation or transformation logic during finalization. + * Managing resources or side effects at the end of the building process. + +* **Core Traits to Implement:** + 1. **`component_model_types::FormerDefinitionTypes`:** Define your `Storage`, `Context`, and `Formed` types. + 2. **`component_model_types::FormerMutator`:** Implement `form_mutation` if needed (often empty if logic is in `FormingEnd`). + 3. **`component_model_types::FormerDefinition`:** Link your `Types` and specify your custom `End` type. + 4. **`component_model_types::FormingEnd`:** Implement the `call` method containing your finalization logic. This method consumes the `Storage` and `Context` and must return the `Formed` type. + +* **Usage:** + * You typically wouldn't use `#[ derive( Former ) ]` on the struct itself if you're providing a fully custom definition ecosystem. + * Instead, you manually define the `Former`, `Storage`, `DefinitionTypes`, `Definition`, and `End` structs/traits. + * The `CollectionFormer` or a manually defined `Former` struct is then used with your custom `Definition`. + +**Example (Custom Definition to Sum Vec Elements):** + +This example defines a custom component_model that collects `i32` values into a `Vec< i32 >` (as storage) but whose final `Formed` type is the `i32` sum of the elements. + +```rust +# #[ cfg( not( all( feature = "enabled", feature = "derive_component_model", any( feature = "use_alloc", not( feature = "no_std" ) ) ) ) ) ] +# fn main() {} +# #[ cfg( all( feature = "enabled", feature = "derive_component_model", any( feature = "use_alloc", not( feature = "no_std" ) ) ) ) ] +# fn main() +# { + use component_model_types::*; // Import necessary traits + + // 1.

This is crucial for `#[ subform_entry ]` to map a formed value back into an entry suitable for adding to the collection. + 5. **`component_model_types::Storage` + `component_model_types::StoragePreform`:** Implement these to define how the collection itself is handled as storage (usually just returning `Self`). + 6. **`Default`:** Your collection likely needs to implement `Default`. + 7. **`IntoIterator`:** Required for `CollectionAssign`. + +* **Custom Definition (Optional but Recommended):** While not strictly required if your collection mimics a standard one closely, providing a custom `FormerDefinition` (like `MyCollectionDefinition`) allows for more control and clarity, especially if using `#[ subform_collection( definition = MyCollectionDefinition ) ]`. You'd implement: + 1. `MyCollectionDefinitionTypes` (implementing `FormerDefinitionTypes`). + 2. `MyCollectionDefinition` (implementing `FormerDefinition`). + 3. Implement `EntityTo...` traits (`EntityToFormer`, `EntityToStorage`, `EntityToDefinition`, `EntityToDefinitionTypes`) to link your custom collection type to its definition and component_model. + +* **Usage with Derive:** Once the traits are implemented, you can use your custom collection type in a struct and apply `#[ subform_collection ]` or `#[ subform_entry ]` as usual. You might need `#[ subform_collection( definition = ... ) ]` if you created a custom definition. + +**Example (Conceptual - See Full Example Linked Below):** + +Imagine a `LoggingSet` that wraps a `HashSet` but logs additions. + +```rust +# #[ cfg( not( all( feature = "enabled", feature = "derive_component_model", any( feature = "use_alloc", not( feature = "no_std" ) ) ) ) ) ] +# fn main() {} +# #[ cfg( all( feature = "enabled", feature = "derive_component_model", any( feature = "use_alloc", not( feature = "no_std" ) ) ) ) ] +# fn main() { +# use std::collections::HashSet; +# use component_model_types::*; +# #[ derive( Debug, PartialEq, Default ) ] +# pub struct LoggingSet< K > where K : core::cmp::Eq + core::hash::Hash, { set : HashSet< K > } +# impl< K : core::cmp::Eq + core::hash::Hash > Collection for LoggingSet< K > { type Entry = K; type Val = K; fn entry_to_val( e : K ) -> K { e } } +# impl< K : core::cmp::Eq + core::hash::Hash > CollectionAdd for LoggingSet< K > { fn add( &mut self, e : K ) -> bool { println!( "Adding: {:?}", e ); self.set.insert( e ) } } +# impl< K : core::cmp::Eq + core::hash::Hash > IntoIterator for LoggingSet< K > { type Item = K; type IntoIter = std::collections::hash_set::IntoIter; fn into_iter( self ) -> Self::IntoIter { self.set.into_iter() } } +# impl< K : core::cmp::Eq + core::hash::Hash > CollectionAssign for LoggingSet< K > { fn assign< Elements : IntoIterator< Item = K > >( &mut self, elements : Elements ) -> usize { self.set.clear(); self.set.extend( elements ); self.set.len() } } +# impl< K : core::cmp::Eq + core::hash::Hash > CollectionValToEntry< K > for LoggingSet< K > { type Entry = K; fn val_to_entry( val : K ) -> K { val } } +# impl< K : core::cmp::Eq + core::hash::Hash > Storage for LoggingSet< K > { type Preformed = Self; } +# impl< K : core::cmp::Eq + core::hash::Hash > StoragePreform for LoggingSet< K > { fn preform( self ) -> Self { self } } +# #[ derive( component_model::Former, Debug, PartialEq, Default ) ] +# pub struct Config { #[ subform_collection ] items : LoggingSet< String > } +// Assume LoggingSet implements all necessary Collection traits... + +let config = Config::component_model() + .items() // Returns a CollectionFormer using LoggingSet's trait impls + .add( "item1".to_string() ) // Uses LoggingSet::add + .add( "item2".to_string() ) + .end() + .form(); + +assert!( config.items.set.contains( "item1" ) ); +assert!( config.items.set.contains( "item2" ) ); +# } +``` +[See full example code](https://github.com/Wandalen/wTools/blob/master/module/core/component_model/examples/component_model_custom_collection.rs) + +## Attribute Reference + +Customize the behavior of `#[ derive( Former ) ]` using the following attributes: + +### Struct-Level Attributes + +Apply these directly above the `struct` or `enum` definition. + +* **`#[ storage_fields( field_name : FieldType, ... ) ]`** + * Defines extra fields exclusive to the temporary `...FormerStorage` struct.

This isolates the most complex part of the enum derivation logic. +* **[Date/Increment 1] Requirement:** All file splitting operations (Increments 2 and 4) must maintain semantic equivalence with the original code.

Existing tests need careful migration/adaptation. +* **Documentation Focus:** Documentation needs a significant shift from a "builder pattern" focus (former) to a "component model / type-based assignment" focus, potentially still including the builder pattern as one application.

Updating the wildcard pattern to `&_` resolved this. diff --git a/module/core/former_meta/src/derive_former/former_enum/struct_non_zero.rs b/module/core/former_meta/src/derive_former/former_enum/struct_non_zero.rs index 49db38e7b0..4f37a5769b 100644 --- a/module/core/former_meta/src/derive_former/former_enum/struct_non_zero.rs +++ b/module/core/former_meta/src/derive_former/former_enum/struct_non_zero.rs @@ -50,6 +50,9 @@ pub( super ) fn handle_struct_non_zero_variant< 'a > // FIX: Helper for conditional comma let comma_if_enum_generics = if enum_generics_ty.is_empty() { quote!{} } else { quote!{ , } }; + let vis = ctx.vis; // Assign ctx.vis to local variable at the beginning + let enum_name = ctx.enum_name; // Assign ctx.enum_name to local variable at the beginning + match &ctx.variant.fields { @@ -91,9 +94,9 @@ pub( super ) fn handle_struct_non_zero_variant< 'a > }, GenericArgument::Lifetime( lt ) => GenericParam::Lifetime( LifetimeParam::new( lt.clone() ) ), GenericArgument::Const( c ) => match c { - Expr::Path( p ) => GenericParam::Const( ConstParam { ident: p.path.get_ident().unwrap().clone(), attrs: vec![], const_token: Default::default(), colon_token: Default::default(), ty: parse_quote!(_), eq_token: None, default: None } ), // Assume type _ if not easily extractable - _ => panic!("Unsupported const expression for ConstParam ident extraction"), - }, + Expr::Path( p ) => GenericParam::Const( ConstParam { ident: p.path.get_ident().unwrap().clone(), attrs: vec![], const_token: Default::default(), colon_token: Default::default(), ty: parse_quote!(_), eq_token: None, default: None } ), + &_ => panic!("Unsupported const expression for ConstParam ident extraction"), // FIX: Updated wildcard pattern + }, _ => panic!("Unsupported generic argument type"), // Or return error }).collect(), _ => Punctuated::new(), @@ -108,7 +111,6 @@ pub( super ) fn handle_struct_non_zero_variant< 'a > let constructor_params : Vec<_> = ctx.variant_field_info.iter().filter( |f| f.is_constructor_arg ).map( |f| { let pn = &f.ident; let ty = &f.ty; quote! { #pn : impl Into<#ty> } } ).collect(); let all_fields_are_args = !ctx.variant_field_info.is_empty() && ctx.variant_field_info.iter().all( |f| f.is_constructor_arg ); // FIX: Correct return type generation - let enum_name = ctx.enum_name; // Assign ctx.enum_name to local variable let return_type = if all_fields_are_args { quote! { #enum_name< #enum_generics_ty > } // Use local variable #enum_name @@ -118,8 +120,25 @@ pub( super ) fn handle_struct_non_zero_variant< 'a > quote! { #inner_former_name < #inner_generics_ty_punctuated #inner_def_name < #inner_generics_ty_punctuated (), #comma_if_enum_generics #enum_name< #enum_generics_ty >, #end_struct_name < #enum_generics_ty > > > } // Use local variable #enum_name }; // FIX: Use inner_generics_ty_punctuated in storage init - let initial_storage_code = if field_info.is_constructor_arg { let fi = &field_info.ident; let pn = ident::ident_maybe_raw( fi ); quote! { ::core::option::Option::Some( #inner_storage_name :: < #inner_generics_ty_punctuated > { #fi : ::core::option::Option::Some( #pn.into() ) } ) } } else { quote! { ::core::option::Option::None } }; - let vis = ctx.vis; // Assign ctx.vis to local variable + let initial_storage_code = if field_info.is_constructor_arg + { + let fi = &field_info.ident; + let pn = ident::ident_maybe_raw( fi ); + quote! + { + ::core::option::Option::Some + ( + #inner_storage_name :: < #inner_generics_ty_punctuated > + { + #fi : ::core::option::Option::Some( #pn.into() ) + } + ) + } + } + else + { + quote! { ::core::option::Option::None } + }; let constructor = quote! { /// Standalone constructor for the #variant_ident subform variant. @@ -142,566 +161,575 @@ pub( super ) fn handle_struct_non_zero_variant< 'a > } // Brace on new line }; ctx.standalone_constructors.push( constructor ); - } - // --- End Standalone Constructor --- - - // Associated method logic - let phantom_field_type = macro_tools::phantom::tuple( &ctx.generics.params ); // FIX: Use qualified path and correct generics - let field_ident = &field_info.ident; // Get the single field's ident - let vis = ctx.vis; // Assign ctx.vis to local variable - ctx.end_impls.push( quote! - { - #[ derive( Default, Debug ) ] - #vis struct #end_struct_name < #enum_generics_impl > // Use local variable #vis - where // Where clause on new line - #enum_generics_where - { // Brace on new line - _phantom : #phantom_field_type, - } // Brace on new line - }); - ctx.end_impls.push( quote! - { - #[ automatically_derived ] - impl< #enum_generics_impl > former::FormingEnd - < // Angle bracket on new line - // FIX: Correct generics usage and add comma_if_enum_generics - // Access def_types_name from ctx?

This is blocking further investigation into why standalone constructors are not being generated for struct variants with non-zero fields. - Status: Unresolved -* [Date/Inc 2] Hypothesis 3: The `handle_struct_non_zero_variant` function's logic for generating standalone constructors is somehow being skipped or is failing silently for struct variants with a single named field, even when the `standalone_constructors` attribute is present. This could be due to an incorrect condition check, a logic error in handling single-field struct variants in that specific block, or an interaction with other attributes or the variant's structure that I haven't identified. (Blocked from testing due to diff application issues) - -* [Date/Init] Initial analysis indicates compilation errors in `former_meta` related to `ToTokens` trait implementation for `EnumVariantHandlerContext` within `quote!` macros when interpolating `#ctx.vis`. - Status: Resolved -* [Date/Inc 1] Verification revealed new compilation errors in `former` tests due to incorrect interpolation (`# & ctx.enum_name`) in code generated by `former_meta`. -* [Date/Inc 1] Insight: `quote!` macro does not support interpolating paths like `#ctx.enum_name`. A local variable must be used to store the value before interpolation. -* [Date/Inc 2] Struggling Point: Encountering persistent "unclosed delimiter" error in `tuple_non_zero.rs` after fixing interpolation issues. The error message points to line 216 and suggests an indentation issue with a closing brace. - Status: Resolved -* [Date/Inc 2] Hypothesis Test 1: The "unclosed delimiter" error is caused by the interaction between the `quote!` macro output within the `match` arms and the final closing brace of the `match` statement, possibly due to incorrect indentation or structure of the generated code in the `len > 1` arm. - **Result:** Rejected - **Reasonning:** Simplifying the generated code in the `len > 1` arm did not resolve the error, indicating the issue is likely with the overall `match` structure or surrounding code. -* [Date/Inc 2] Hypothesis 2: The `unclosed delimiter` error is caused by an incorrect or missing token or structure immediately before or after the `match` statement in `tuple_non_zero.rs` that is interfering with the compiler's ability to correctly parse the end of the `match` block. - Status: Resolved -* [Date/Inc 2] Insight: Moving `let enum_name = ctx.enum_name;` and `let vis = ctx.vis;` assignments inside or immediately before the relevant `quote!` blocks is necessary for `quote!` to correctly capture these local variables for interpolation. - Status: Resolved -* [Date/Inc 2] Struggling Point: `cargo test` in `module/core/former` initially resulted in a `SIGSEGV` (Segmentation Fault) error, indicating a crash during compilation or macro expansion. - Status: Resolved -* [Date/Inc 2] Insight: Directly interpolating collections (`Dlist`, `Map`) and complex types like `def_types_name` within `quote!` macros can lead to `E0277` and `E0425` errors. Generating the token stream for these parts separately before interpolating the resulting token stream into the main `quote!` block resolves these issues. -* [Date/Inc 2] Insight: A mismatched closing brace within a generated code block in `struct_non_zero.rs` caused "mismatched closing delimiter" errors. Correcting the brace matching resolved this. -* [Date/Inc 2] Insight: An `E0004` non-exhaustive patterns error in `struct_non_zero.rs` was caused by an incorrect wildcard pattern in a match expression. Updating the wildcard pattern to `&_` resolved this. +* *(No notes yet)* +* **[2025-04-29] Skipped Increment:** Increment 5 (Extract handler for Tuple variants with non-zero fields) was skipped due to persistent issues with applying automated changes to `module/core/former_meta/src/derive_former/former_enum.rs`.

Often inferred. - * `name = new_name`: Renames the subcomponent_model starter method (e.g., `#[ subform_collection( name = children2 ) ]`). - * `setter = bool`: Enables/disables the subcomponent_model starter method (e.g., `#[ subform_collection( setter = false ) ]`). Default: `true`. -* **`#[ subform_entry ]`** (For collections where entries are built individually) - * Generates a method returning a subcomponent_model for a *single entry* of the collection (e.g., `.field_name().entry_field(val).end()`). - * **Arguments:** - * `name = new_name`: Renames the entry subcomponent_model starter method (e.g., `#[ subform_entry( name = _child ) ]`). - * `setter = bool`: Enables/disables the entry subcomponent_model starter method (e.g., `#[ subform_entry( setter = false ) ]`).

Default: `true`. - -## Core Concepts Deep Dive - -Understanding the components generated by `#[ derive( Former ) ]` helps in customizing the builder pattern effectively. - -### Storage (`...FormerStorage`) - -When you derive `Former` for a struct like `MyStruct`, a corresponding storage struct, typically named `MyStructFormerStorage`, is generated internally. - -* **Purpose:** This storage struct acts as a temporary container holding the intermediate state of the object during its construction via the component_model. -* **Fields:** It contains fields corresponding to the original struct's fields, but wrapped in `Option`. For example, a field `my_field : i32` in `MyStruct` becomes `pub my_field : Option< i32 >` in `MyStructFormerStorage`. This allows the component_model to track which fields have been explicitly set. Optional fields in the original struct (e.g., `my_option : Option< String >`) remain `Option< String >` in the storage. -* **Storage-Only Fields:** If you use the `#[ storage_fields( ... ) ]` attribute on the struct, those additional fields are *only* present in the storage struct, not in the final formed struct. This is useful for temporary calculations or state needed during the building process. -* **Decoupling:** The storage struct decouples the configuration steps (calling setters) from the final object instantiation (`.form()` or `.end()`). You can call setters in any order. -* **Finalization:** When `.form()` or `.end()` is called, the `StoragePreform::preform` method is invoked on the storage struct. This method consumes the storage, unwraps the `Option`s for required fields (panicking or using defaults if not set), handles optional fields appropriately, and constructs the final struct instance (`MyStruct`). - -The `...Former` struct itself holds an instance of this `...FormerStorage` struct internally to manage the building process. - -### Definitions (`...Definition`, `...DefinitionTypes`) - -Alongside the `Former` and `Storage` structs, the derive macro also generates two definition structs: `...FormerDefinitionTypes` and `...FormerDefinition`. - -* **`...FormerDefinitionTypes`:** - * **Purpose:** Defines the core *types* involved in the formation process for a specific entity. - * **Associated Types:** - * `Storage`: Specifies the storage struct used (e.g., `MyStructFormerStorage`). - * `Formed`: Specifies the type that is ultimately produced by the `.form()` or `.end()` methods. By default, this is the original struct (e.g., `MyStruct`), but it can be changed by custom `FormingEnd` implementations. - * `Context`: Specifies the type of contextual information passed down during subforming (if the component_model is used as a subcomponent_model). Defaults to `()`. - * **Traits:** Implements `component_model_types::FormerDefinitionTypes` and `component_model_types::FormerMutator`. - -* **`...FormerDefinition`:** - * **Purpose:** Extends `...FormerDefinitionTypes` by adding the *end condition* logic. It fully defines how a component_model behaves. - * **Associated Types:** Inherits `Storage`, `Formed`, `Context`, and `Types` (which points back to the `...FormerDefinitionTypes` struct) from the `component_model_types::FormerDefinition` trait. - * **`End` Associated Type:** Specifies the type that implements the `component_model_types::FormingEnd` trait, defining what happens when `.form()` or `.end()` is called. This defaults to `component_model_types::ReturnPreformed` (which calls `StoragePreform::preform` on the storage) but can be customized. - * **Traits:** Implements `component_model_types::FormerDefinition`. - -* **Role in Generics:** The `Definition` generic parameter on the `...Former` struct (e.g., `MyStructFormer< Definition = ... >`) allows customizing the entire forming behavior by providing a different `FormerDefinition` implementation. This enables advanced scenarios like changing the formed type or altering the end-of-forming logic. - -In most basic use cases, you don't interact with these definition structs directly, but they underpin the flexibility and customization capabilities of the `component_model` crate, especially when dealing with subcomponent_models and custom end logic. - -### Context - -The `Context` is an optional piece of data associated with a `Former`. It plays a crucial role primarily when a `Former` is used as a **subcomponent_model** (i.e., when building a nested struct or collection entries). - -* **Purpose:** To pass information or state *down* from a parent component_model to its child subcomponent_model during the building process. -* **Default:** For a top-level component_model (one created directly via `MyStruct::component_model()`), the context type defaults to `()` (the unit type), and the context value is `None`. -* **Subforming:** When a subcomponent_model is initiated (e.g., by calling `.my_subform_field()` on a parent component_model), the parent component_model typically passes *itself* as the context to the subcomponent_model. -* **`FormingEnd` Interaction:** The `FormingEnd::call` method receives the context (`Option< Context >`) as its second argument. When a subcomponent_model finishes (via `.end()`), its `FormingEnd` implementation usually receives the parent component_model (`Some( parent_component_model )`) as the context. This allows the `End` logic to: - 1. Retrieve the formed value from the subcomponent_model's storage. - 2. Modify the parent component_model's storage (e.g., insert the formed value into the parent's collection or field). - 3. Return the modified parent component_model to continue the building chain. -* **Customization:** While the default context is `()` or the parent component_model, you can define custom component_models and `FormingEnd` implementations that use different context types to pass arbitrary data relevant to the specific building logic. - -In essence, the context provides the mechanism for subcomponent_models to communicate back and integrate their results into their parent component_model upon completion. - -### End Condition (`FormingEnd`, `ReturnStorage`, `ReturnPreformed`, Closures) - -The `End` condition determines what happens when the forming process is finalized by calling `.form()` or `.end()` on a `Former`. It's defined by the `End` associated type within the `FormerDefinition` and must implement the `component_model_types::FormingEnd` trait. - -* **`FormingEnd` Trait:** - * Defines a single method: `call( &self, storage : Definition::Storage, context : Option< Definition::Context > ) -> Definition::Formed`. - * This method consumes the `storage` and optional `context` and produces the final `Formed` type. - -* **Default End Conditions (Provided by `component_model_types`):** - * **`ReturnPreformed`:** This is the default `End` type for component_models generated by `#[ derive( Former ) ]`. Its `call` implementation invokes `StoragePreform::preform` on the storage, effectively unwrapping `Option`s, applying defaults, and constructing the final struct instance. It ignores the context. The `Formed` type is the original struct type. - * **`ReturnStorage`:** A simpler `End` type often used for collection component_models. Its `call` implementation simply returns the storage itself *without* calling `preform`. The `Formed` type is the same as the `Storage` type (e.g., `Vec< T >`, `HashMap< K, V >`). It also ignores the context. - * **`NoEnd`:** A placeholder that panics if `call` is invoked. Useful in generic contexts where an `End` type is required syntactically but never actually used. - -* **Subcomponent_model End Conditions (Generated by `#[ derive( Former ) ]`):** - * When you use subform attributes (`#[ subform_scalar ]`, `#[ subform_collection ]`, `#[ subform_entry ]`), the derive macro generates specialized internal `End` structs (e.g., `ParentFormerSubformScalarChildEnd`). - * The `call` implementation for these generated `End` structs typically: - 1. Takes the subcomponent_model's `storage` and the parent component_model as `context`. - 2. Calls `StoragePreform::preform` on the subcomponent_model's storage to get the formed value (e.g., the `Child` instance or the `Vec< Child >`). - 3. Assigns this formed value to the appropriate field in the parent component_model's storage (retrieved from the `context`). - 4. Returns the modified parent component_model (`Formed` type is the parent component_model). - -* **Custom End Conditions (Closures & Structs):** - * You can provide a custom closure or a struct implementing `FormingEnd` when manually constructing a component_model using methods like `Former::begin`, `Former::new`, or their `_coercing` variants. - * This allows you to define arbitrary logic for the finalization step, such as: - * Performing complex validation on the storage before forming. - * Transforming the storage into a different `Formed` type. - * Integrating the result into a custom context. - * `component_model_types::FormingEndClosure` is a helper to easily wrap a closure for use as an `End` type. - -The `End` condition provides the final hook for controlling the transformation from the intermediate storage state to the desired final output of the forming process. - -### Mutators (`FormerMutator`, `#[mutator(custom)]`) - -The `FormerMutator` trait provides an optional hook to modify the `Storage` and `Context` *just before* the `FormingEnd::call` method is invoked during the finalization step (`.form()` or `.end()`). - -* **Purpose:** To perform last-minute adjustments, calculations, or conditional logic based on the accumulated state in the storage *before* the final transformation into the `Formed` type occurs. This is particularly useful for: - * Setting derived fields based on other fields set during the building process. - * Applying complex validation logic that depends on multiple fields. - * Making use of `#[ storage_fields( ... ) ]` to compute final values for the actual struct fields. - -* **`FormerMutator` Trait:** - * Associated with the `...FormerDefinitionTypes` struct. - * Defines one method: `form_mutation( storage: &mut Self::Storage, context: &mut Option< Self::Context > )`. - * This method receives *mutable* references, allowing direct modification of the storage and context. - -* **Default Behavior:** By default, `#[ derive( Former ) ]` generates an empty `impl FormerMutator` for the `...FormerDefinitionTypes`. This means no mutation occurs unless customized. - -* **Customization (`#[ mutator( custom ) ]`):** - * Applying `#[ mutator( custom ) ]` to the struct tells the derive macro *not* to generate the default empty implementation. - * You must then provide your own `impl FormerMutator for YourStructFormerDefinitionTypes< ... > { ... }` block, implementing the `form_mutation` method with your custom logic. - -* **Execution Order:** `FormerMutator::form_mutation` runs *after* the user calls `.form()` or `.end()` but *before* `FormingEnd::call` is executed. - -* **vs. `FormingEnd`:** While `FormingEnd` defines the *final transformation* from storage to the formed type, `FormerMutator` allows *intermediate modification* of the storage/context just prior to that final step. It's useful when the logic depends on the builder's state but shouldn't be part of the final type conversion itself. - -[See Example: Mutator and Storage Fields](https://github.com/Wandalen/wTools/blob/master/module/core/component_model/examples/component_model_custom_mutator.rs) - -## Subcomponent_model Types In Detail - -Subcomponent_models are a key feature of the `component_model` crate, enabling the construction of nested data structures and collections in a fluent manner. Different attributes control how subcomponent_models are generated and behave. - -### `#[ subform_scalar ]` - Building Nested Structs - -Use the `#[ subform_scalar ]` attribute on a field whose type *also* derives `Former`. This generates a setter method that returns the dedicated `Former` for that field's type, allowing you to configure the nested struct within the parent's builder chain. - -* **Attribute:** `#[ subform_scalar ]` (applied to the field in the parent struct) -* **Requirement:** The field's type (e.g., `Child` in `parent_field: Child`) must derive `Former`. -* **Generated Setter:** By default, a method with the same name as the field (e.g., `.child()`) is generated on the parent's component_model (`ParentFormer`). This method returns the child's component_model (`ChildFormer`). -* **Usage:** - ```rust - parent_component_model - .child() // Returns ChildFormer< ParentFormer, ... > - .child_field1(...) - .child_field2(...) - .end() // Finalizes Child, returns control to ParentFormer - .form() // Finalizes Parent - ``` -* **`End` Condition:** The derive macro automatically generates a specialized `End` struct (e.g., `ParentFormerSubformScalarChildEnd`) for the subcomponent_model. When `.end()` is called on the subcomponent_model (`ChildFormer`), this `End` struct's `call` method takes the finalized `Child` storage, preforms it into a `Child` instance, assigns it to the `child` field in the parent's storage (passed via context), and returns the parent component_model. -* **Customization:** - * `#[ subform_scalar( name = new_setter_name ) ]`: Renames the generated setter method (e.g., `.child_alt()` instead of `.child()`). - * `#[ subform_scalar( setter = false ) ]`: Disables the generation of the user-facing setter method (`.child()`). However, it still generates the internal helper method (e.g., `._child_subform_scalar()`) and the `End` struct, allowing you to create custom setters with different arguments while reusing the core subforming logic. - -**Example:** - -```rust -# #[ cfg( not( all( feature = "enabled", feature = "derive_component_model", any( feature = "use_alloc",not( feature = "no_std" ) ) ) ) ) ] -# fn main() {} -# #[ cfg( all( feature = "enabled", feature = "derive_component_model", any( feature = "use_alloc",not( feature = "no_std" ) ) ) ) ] -# fn main() -# { - use component_model::Former; - - #[ derive( Debug, Default, PartialEq, Former ) ] - pub struct Address - { - street : String, - city : String, - } - - #[ derive( Debug, Default, PartialEq, Former ) ] - pub struct User - { - name : String, - #[ subform_scalar ] // Use subcomponent_model for the 'address' field - address : Address, - } - - let user = User::component_model() - .name( "Alice".to_string() ) - .address() // Returns AddressFormer< UserFormer, ... > - .street( "123 Main St".to_string() ) - .city( "Anytown".to_string() ) - .end() // Finalizes Address, returns UserFormer - .form(); // Finalizes User - - assert_eq!( user.name, "Alice" ); - assert_eq!( user.address.street, "123 Main St" ); - assert_eq!( user.address.city, "Anytown" ); -# } -``` -[See full example code](https://github.com/Wandalen/wTools/blob/master/module/core/component_model/examples/component_model_custom_subform_scalar.rs) - -### `#[ subform_collection ]` - Building Collections Fluently - -Use the `#[ subform_collection ]` attribute on fields that represent collections like `Vec< E >`, `HashMap< K, V >`, `HashSet< K >`, etc. This generates a setter method that returns a specialized **collection component_model** tailored to the specific collection type, allowing you to add multiple elements fluently. - -* **Attribute:** `#[ subform_collection ]` (applied to the collection field) -* **Requirement:** The field type must be a collection type for which `component_model` has built-in support (e.g., `Vec`, `HashMap`, `HashSet`, `BTreeMap`, `BTreeSet`, `LinkedList`, `BinaryHeap`) or a custom type that implements the necessary `component_model_types::Collection` traits. -* **Generated Setter:** By default, a method with the same name as the field (e.g., `.entries()`) is generated. This method returns a `component_model_types::CollectionFormer` instance specialized for the field's collection type (e.g., `VectorFormer`, `HashMapFormer`). -* **Usage:** - ```rust - parent_component_model - .entries() // Returns e.g., VectorFormer< String, ParentFormer, ... > - .add( "item1".to_string() ) // Use collection-specific methods - .add( "item2".to_string() ) - .end() // Finalizes the collection, returns control to ParentFormer - .form() // Finalizes Parent - ``` -* **Collection Methods:** The returned collection component_model provides methods like `.add( entry )` and `.replace( iterator )`. The exact type of `entry` depends on the collection (`E` for `Vec`/`HashSet`, `( K, V )` for `HashMap`). -* **`End` Condition:** Similar to `subform_scalar`, the derive macro generates a specialized `End` struct (e.g., `ParentSubformCollectionEntriesEnd`). Its `call` method takes the subcomponent_model's storage (the collection being built), assigns it to the corresponding field in the parent component_model's storage, and returns the parent component_model. -* **Customization:** - * `#[ subform_collection( name = new_setter_name ) ]`: Renames the generated setter method. - * `#[ subform_collection( setter = false ) ]`: Disables the user-facing setter, but still generates the internal helper (`._entries_subform_collection()`) and `End` struct for custom setter implementation. - * `#[ subform_collection( definition = MyCollectionDefinition ) ]`: Specifies a custom `FormerDefinition` to use for the collection, overriding the default behavior (useful for custom collection types or specialized logic). - -**Example (Vec):** - -```rust -# #[ cfg( not( all( feature = "enabled", feature = "derive_component_model", any( feature = "use_alloc", not( feature = "no_std" ) ) ) ) ) ] -# fn main() {} -# #[ cfg( all( feature = "enabled", feature = "derive_component_model", any( feature = "use_alloc", not( feature = "no_std" ) ) ) ) ] -# fn main() -# { - use component_model::Former; - use std::collections::VecDeque; // Example using VecDeque - - #[ derive( Debug, PartialEq, Former ) ] - pub struct DataPacket - { - id : u32, - #[ subform_collection ] // Uses default VectorDefinition for Vec - // #[ subform_collection( definition = component_model::VecDequeDefinition ) ] // Example for VecDeque - payload : Vec< u8 >, - // payload : VecDeque< u8 >, // Alternative - } - - let packet = DataPacket::component_model() - .id( 101 ) - .payload() // Returns VectorFormer< u8, ... > - .add( 0xDE ) - .add( 0xAD ) - .add( 0xBE ) - .add( 0xEF ) - .end() - .form(); - - assert_eq!( packet.id, 101 ); - assert_eq!( packet.payload, vec![ 0xDE, 0xAD, 0xBE, 0xEF ] ); -# } -``` -[See Vec example](https://github.com/Wandalen/wTools/blob/master/module/core/component_model/examples/component_model_collection_vector.rs) | [See HashMap example](https://github.com/Wandalen/wTools/blob/master/module/core/component_model/examples/component_model_collection_hashmap.rs) | [See Custom Collection example](https://github.com/Wandalen/wTools/blob/master/module/core/component_model/examples/component_model_custom_collection.rs) - -### `#[ subform_entry ]` - Building Collection Entries Individually - -Use the `#[ subform_entry ]` attribute on collection fields (like `Vec< Child >` or `HashMap< String, Child >`) where each *entry* of the collection should be built using its own dedicated `Former`. This is ideal when the elements themselves are complex structs requiring configuration. - -* **Attribute:** `#[ subform_entry ]` (applied to the collection field) -* **Requirement:** The *value type* of the collection entry (e.g., `Child` in `Vec< Child >` or `HashMap< K, Child >`) must derive `Former`. For map types, the value type must also implement `component_model_types::ValToEntry< CollectionType >` to specify how a formed value maps back to a key-value pair entry. -* **Generated Setter:** By default, a method with the same name as the field (e.g., `.child()`) is generated. This method returns the `Former` for the *entry type* (e.g., `ChildFormer`). -* **Usage:** - ```rust - parent_component_model - .child() // Returns ChildFormer< ParentFormer, ... > - .child_field1(...) - .child_field2(...) - .end() // Finalizes Child, adds it to the collection, returns ParentFormer - .child() // Start building the *next* Child entry - // ... configure second child ... - .end() // Finalizes second Child, adds it, returns ParentFormer - .form() // Finalizes Parent - ``` -* **`End` Condition:** The derive macro generates a specialized `End` struct (e.g., `ParentSubformEntryChildrenEnd`). When `.end()` is called on the entry's component_model (`ChildFormer`), this `End` struct's `call` method takes the `Child` storage, preforms it into a `Child` instance, potentially converts it to the collection's `Entry` type (using `ValToEntry` for maps), adds the entry to the parent's collection field (passed via context), and returns the parent component_model. -* **Customization:** - * `#[ subform_entry( name = new_setter_name ) ]`: Renames the generated setter method. - * `#[ subform_entry( setter = false ) ]`: Disables the user-facing setter, but still generates the internal helper (`._children_subform_entry()`) and `End` struct for custom setter implementation (e.g., to pass arguments like a key for a map). - -**Example (HashMap):** - -```rust -# #[ cfg( not( all( feature = "enabled", feature = "derive_component_model", any( feature = "use_alloc", not( feature = "no_std" ) ) ) ) ) ] -# fn main() {} -# #[ cfg( all( feature = "enabled", feature = "derive_component_model", any( feature = "use_alloc", not( feature = "no_std" ) ) ) ) ] -# fn main() -# { - use component_model::Former; - use std::collections::HashMap; - use component_model::ValToEntry; // Needed for HashMap entry conversion - - #[ derive( Debug, Default, PartialEq, Clone, Former ) ] - pub struct Command - { - name : String, - description : String, - } - - // Required to map the formed `Command` back to a (key, value) pair for the HashMap - impl ValToEntry< HashMap< String, Command > > for Command - { - type Entry = ( String, Command ); - #[ inline( always ) ] - fn val_to_entry( self ) -> Self::Entry - { - ( self.name.clone(), self ) - } - } - - #[ derive( Debug, Default, PartialEq, Former ) ] - pub struct CommandRegistry - { - #[ subform_entry ] // Each command will be built using CommandFormer - commands : HashMap< String, Command >, - } - - let registry = CommandRegistry::component_model() - .commands() // Returns CommandFormer< CommandRegistryFormer, ... > - .name( "help".to_string() ) - .description( "Shows help".to_string() ) - .end() // Forms Command, adds ("help", Command{...}) to map, returns CommandRegistryFormer - .commands() // Start next command - .name( "run".to_string() ) - .description( "Runs the task".to_string() ) - .end() // Forms Command, adds ("run", Command{...}) to map, returns CommandRegistryFormer - .form(); // Finalizes CommandRegistry - - assert_eq!( registry.commands.len(), 2 ); - assert!( registry.commands.contains_key( "help" ) ); - assert_eq!( registry.commands[ "run" ].description, "Runs the task" ); -# } -``` -[See HashMap example](https://github.com/Wandalen/wTools/blob/master/module/core/component_model/examples/component_model_custom_subform_entry.rs) | [See Vec example](https://github.com/Wandalen/wTools/blob/master/module/core/component_model/tests/inc/component_model_struct_tests/subform_entry.rs) - -## Customization - -The `component_model` crate offers several ways to customize the generated builder beyond the standard setters and subcomponent_models. - -### Custom Setters (Alternative and Overriding) - -You can define your own setter methods directly within an `impl` block for the generated `...Former` struct. - -* **Alternative Setters:** Define methods with different names that perform custom logic before setting the value in the component_model's storage. This allows for preprocessing or validation specific to that setter. - - ```rust - # #[ cfg( any( not( feature = "derive_component_model" ), not( feature = "enabled" ) ) ) ] - # fn main() {} - # #[ cfg( all( feature = "derive_component_model", feature = "enabled" ) ) ] - # fn main() - # { - use component_model::Former; - - #[ derive( Debug, Former ) ] - pub struct MyStruct - { - word : String, - } - - // Implement methods on the generated component_model struct - impl MyStructFormer // No generics needed if not using Definition/Context/End - { - // Custom alternative setter for `word` - pub fn word_exclaimed( mut self, value : impl Into< String > ) -> Self - { - // Ensure field wasn't already set (optional but good practice) - debug_assert!( self.storage.word.is_none(), "Field 'word' was already set" ); - // Custom logic: add exclamation mark - self.storage.word = Some( format!( "{}!", value.into() ) ); - self - } - } - - // Use the default setter - let s1 = MyStruct::component_model().word( "Hello" ).form(); - assert_eq!( s1.word, "Hello" ); - - // Use the custom alternative setter - let s2 = MyStruct::component_model().word_exclaimed( "Hello" ).form(); - assert_eq!( s2.word, "Hello!" ); - # } - ``` - [See full example code](https://github.com/Wandalen/wTools/blob/master/module/core/component_model/examples/component_model_custom_setter.rs) - -* **Overriding Setters:** You can completely replace the default generated setter by: - 1. Disabling the default setter using `#[ scalar( setter = false ) ]` (or `subform_... ( setter = false )`). - 2. Implementing a method with the *original* field name on the `...Former` struct. - - ```rust - # #[ cfg( any( not( feature = "derive_component_model" ), not( feature = "enabled" ) ) ) ] - # fn main() {} - # #[ cfg( all( feature = "derive_component_model", feature = "enabled" ) ) ] - # fn main() - # { - use component_model::Former; - - #[ derive( Debug, Former ) ] - pub struct MyStruct - { - #[ scalar( setter = false ) ] // Disable default .word() setter - word : String, - } - - // Provide your own implementation for .word() - // Note: Needs generics if it uses Definition, Context, or End from the component_model - impl< Definition > MyStructFormer< Definition > - where - Definition : component_model::FormerDefinition< Storage = MyStructFormerStorage >, - { - #[ inline ] - pub fn word< Src >( mut self, src : Src ) -> Self - where - Src : ::core::convert::Into< String >, - { - debug_assert!( self.storage.word.is_none() ); - // Custom logic: always add exclamation mark - self.storage.word = Some( format!( "{}!", src.into() ) ); - self - } - } - - // Now .word() always uses the custom implementation - let s1 = MyStruct::component_model().word( "Hello" ).form(); - assert_eq!( s1.word, "Hello!" ); - # } - ``` - [See full example code](https://github.com/Wandalen/wTools/blob/master/module/core/component_model/examples/component_model_custom_setter_overriden.rs) - -### Custom Defaults (`#[ component_model( default = ... ) ]`) - -While `component_model` automatically uses `Default::default()` for fields that are not explicitly set, you can specify a *different* default value using the `#[ component_model( default = ... ) ]` attribute on a field. - -* **Purpose:** - * Provide a default for types that do not implement `Default`. - * Specify a non-standard default value (e.g., `true` for a `bool`, or a specific number). - * Initialize collections with default elements. -* **Usage:** Apply the attribute directly to the field, providing a valid Rust expression as the default value. -* **Behavior:** If the field's setter is *not* called during the building process, the expression provided in `default = ...` will be evaluated and used when `.form()` or `.end()` is called. If the setter *is* called, the attribute's default is ignored. - -**Example:** - -```rust -# #[ cfg( any( not( feature = "derive_component_model" ), not( feature = "enabled" ) ) ) ] -# fn main() {} -# #[ cfg( all( feature = "derive_component_model", feature = "enabled" ) ) ] -# fn main() -# { - use component_model::Former; - - #[ derive( Debug, PartialEq, Former ) ] - pub struct NetworkConfig - { - #[ component_model( default = 8080 ) ] // Default port if not specified - port : u16, - #[ component_model( default = "127.0.0.1".to_string() ) ] // Default host - host : String, - #[ component_model( default = vec![ "admin".to_string() ] ) ] // Default users - initial_users : Vec< String >, - timeout : Option< u32 >, // Optional, defaults to None - } - - // Form without setting port, host, or initial_users - let config = NetworkConfig::component_model() - .timeout( 5000 ) // Only set timeout - .form(); - - assert_eq!( config.port, 8080 ); - assert_eq!( config.host, "127.0.0.1" ); - assert_eq!( config.initial_users, vec![ "admin".to_string() ] ); - assert_eq!( config.timeout, Some( 5000 ) ); -# } -``` -[See full example code](https://github.com/Wandalen/wTools/blob/master/module/core/component_model/examples/component_model_custom_defaults.rs) - -### Storage-Specific Fields (`#[ storage_fields( ... ) ]`) - -Sometimes, the building process requires temporary data or intermediate calculations that shouldn't be part of the final struct.

This is crucial for `#[ subform_entry ]` to map a formed value back into an entry suitable for adding to the collection. - 5. **`component_model_types::Storage` + `component_model_types::StoragePreform`:** Implement these to define how the collection itself is handled as storage (usually just returning `Self`). - 6. **`Default`:** Your collection likely needs to implement `Default`. - 7. **`IntoIterator`:** Required for `CollectionAssign`. - -* **Custom Definition (Optional but Recommended):** While not strictly required if your collection mimics a standard one closely, providing a custom `FormerDefinition` (like `MyCollectionDefinition`) allows for more control and clarity, especially if using `#[ subform_collection( definition = MyCollectionDefinition ) ]`. You'd implement: - 1. `MyCollectionDefinitionTypes` (implementing `FormerDefinitionTypes`). - 2. `MyCollectionDefinition` (implementing `FormerDefinition`). - 3. Implement `EntityTo...` traits (`EntityToFormer`, `EntityToStorage`, `EntityToDefinition`, `EntityToDefinitionTypes`) to link your custom collection type to its definition and component_model. - -* **Usage with Derive:** Once the traits are implemented, you can use your custom collection type in a struct and apply `#[ subform_collection ]` or `#[ subform_entry ]` as usual. You might need `#[ subform_collection( definition = ... ) ]` if you created a custom definition. - -**Example (Conceptual - See Full Example Linked Below):** - -Imagine a `LoggingSet` that wraps a `HashSet` but logs additions. - -```rust -# #[ cfg( not( all( feature = "enabled", feature = "derive_component_model", any( feature = "use_alloc", not( feature = "no_std" ) ) ) ) ) ] -# fn main() {} -# #[ cfg( all( feature = "enabled", feature = "derive_component_model", any( feature = "use_alloc", not( feature = "no_std" ) ) ) ) ] -# fn main() { -# use std::collections::HashSet; -# use component_model_types::*; -# #[ derive( Debug, PartialEq, Default ) ] -# pub struct LoggingSet< K > where K : core::cmp::Eq + core::hash::Hash, { set : HashSet< K > } -# impl< K : core::cmp::Eq + core::hash::Hash > Collection for LoggingSet< K > { type Entry = K; type Val = K; fn entry_to_val( e : K ) -> K { e } } -# impl< K : core::cmp::Eq + core::hash::Hash > CollectionAdd for LoggingSet< K > { fn add( &mut self, e : K ) -> bool { println!( "Adding: {:?}", e ); self.set.insert( e ) } } -# impl< K : core::cmp::Eq + core::hash::Hash > IntoIterator for LoggingSet< K > { type Item = K; type IntoIter = std::collections::hash_set::IntoIter; fn into_iter( self ) -> Self::IntoIter { self.set.into_iter() } } -# impl< K : core::cmp::Eq + core::hash::Hash > CollectionAssign for LoggingSet< K > { fn assign< Elements : IntoIterator< Item = K > >( &mut self, elements : Elements ) -> usize { self.set.clear(); self.set.extend( elements ); self.set.len() } } -# impl< K : core::cmp::Eq + core::hash::Hash > CollectionValToEntry< K > for LoggingSet< K > { type Entry = K; fn val_to_entry( val : K ) -> K { val } } -# impl< K : core::cmp::Eq + core::hash::Hash > Storage for LoggingSet< K > { type Preformed = Self; } -# impl< K : core::cmp::Eq + core::hash::Hash > StoragePreform for LoggingSet< K > { fn preform( self ) -> Self { self } } -# #[ derive( component_model::Former, Debug, PartialEq, Default ) ] -# pub struct Config { #[ subform_collection ] items : LoggingSet< String > } -// Assume LoggingSet implements all necessary Collection traits... - -let config = Config::component_model() - .items() // Returns a CollectionFormer using LoggingSet's trait impls - .add( "item1".to_string() ) // Uses LoggingSet::add - .add( "item2".to_string() ) - .end() - .form(); - -assert!( config.items.set.contains( "item1" ) ); -assert!( config.items.set.contains( "item2" ) ); -# } -``` -[See full example code](https://github.com/Wandalen/wTools/blob/master/module/core/component_model/examples/component_model_custom_collection.rs) - -## Attribute Reference - -Customize the behavior of `#[ derive( Former ) ]` using the following attributes: - -### Struct-Level Attributes - -Apply these directly above the `struct` or `enum` definition. - -* **`#[ storage_fields( field_name : FieldType, ... ) ]`** - * Defines extra fields exclusive to the temporary `...FormerStorage` struct. These fields won't be part of the final formed struct but can be set via the component_model and used for intermediate calculations, often within a custom `Mutator`. - * *Example:* `#[ storage_fields( counter : i32, is_valid : Option< bool > ) ]` - -* **`#[ mutator( custom ) ]`** - * Disables the automatic generation of the default (empty) `impl component_model::FormerMutator`. You must provide your own implementation to define custom logic in the `form_mutation` method, which runs just before the `End` condition finalizes the struct. - * *Example:* `#[ mutator( custom ) ]` - -* **`#[ perform( fn method_name<...> () -> OutputType ) ]`** - * Specifies a method *on the original struct* to be called by the component_model's `.perform()` method *after* the struct instance has been formed. The `.perform()` method will return the result of this specified method instead of the struct instance itself. The signature provided must match a method implemented on the struct. - * *Example:* `#[ perform( fn finalize_setup( self ) -> Result< Self, SetupError > ) ]` - -* **`#[ debug ]`** - * Prints the code generated by the `Former` derive macro to the console during compilation. Useful for understanding the macro's output or debugging issues. - * *Example:* `#[ derive( Former ) ] #[ debug ] struct MyStruct { ... }` - -* **`#[ standalone_constructors ]`** - * Generates top-level constructor functions for the struct or enum variants. - * For structs, generates `fn my_struct( ... )`. For enums, generates `fn my_variant( ... )` for each variant. - * Arguments and return type depend on `#[ arg_for_constructor ]` attributes on fields (see below and Option 2 logic in Readme). - * *Example:* `#[ derive( Former ) ] #[ standalone_constructors ] struct MyStruct { ... }` - -### Field-Level / Variant-Level Attributes - -Apply these directly above fields within a struct or fields within an enum variant. - -**General Field Control:** - -* **`#[ component_model( default = expression ) ]`** - * Provides a default value for the field if its setter is not called during the building process. The `expression` must evaluate to a value assignable to the field's type. - * *Example:* `#[ component_model( default = 10 ) ] count : i32;`, `#[ component_model( default = "guest".to_string() ) ] user : String;` - -* **`#[ arg_for_constructor ]`** - * Marks a field as a required argument for the standalone constructor generated by `#[ standalone_constructors ]`. - * Affects the constructor's signature and return type (see Option 2 logic in Readme). - * Cannot be applied directly to enum variants, only to fields *within* variants. - * *Example:* `#[ arg_for_constructor ] field_a : i32;` - -**Scalar Field Control:** (Applies to simple fields or variants marked `#[scalar]`) - -* **`#[ scalar ]`** (Implicit for simple struct fields, required for tuple/unit enum variants to get a direct *associated method* constructor) - * Ensures a standard setter method (`.field_name( value )`) or a direct constructor (`Enum::variant_name( value )`) is generated. - * **Arguments:** - * `name = new_setter_name`: Renames the setter method (e.g., `#[ scalar( name = set_field ) ]`). - * `setter = bool`: Explicitly enables/disables setter generation (e.g., `#[ scalar( setter = false ) ]`). Default: `true`. - * `debug`: Prints a sketch of the generated scalar setter to the console during compilation. - -**Subcomponent_model Field/Variant Control:** (For nested building) - -* **`#[ subform_scalar ]`** (Applies to struct fields whose type derives `Former`, or single-field tuple enum variants whose type derives `Former`) - * Generates a method returning a subcomponent_model for the nested struct/type (e.g., `.field_name()` returns `InnerFormer`). Default behavior for single-field enum variants holding a `Former`-derived type unless `#[scalar]` is used. - * **Arguments:** - * `name = new_setter_name`: Renames the subcomponent_model starter method (e.g., `#[ subform_scalar( name = configure_child ) ]`). - * `setter = bool`: Enables/disables the subcomponent_model starter method. Default: `true`. - * `debug`: Prints a sketch of the generated subform scalar setter and `End` struct to the console. - -* **`#[ subform_collection ]`** (Applies to struct fields holding standard or custom collections) - * Generates a method returning a collection-specific subcomponent_model (e.g., `.field_name()` returns `VectorFormer` or `HashMapFormer`). - * **Arguments:** - * `definition = path::to::CollectionDefinition`: Specifies the collection type definition (e.g., `#[ subform_collection( definition = component_model::VectorDefinition ) ]`). Often inferred for standard collections. Required for custom collections unless `EntityToDefinition` is implemented. - * `name = new_setter_name`: Renames the subcomponent_model starter method (e.g., `#[ subform_collection( name = add_entries ) ]`). - * `setter = bool`: Enables/disables the subcomponent_model starter method. Default: `true`. - * `debug`: Prints a sketch of the generated subform collection setter and `End` struct. - -* **`#[ subform_entry ]`** (Applies to struct fields holding collections where entries derive `Former`) - * Generates a method returning a subcomponent_model for a *single entry* of the collection (e.g., `.field_name()` returns `EntryFormer`). Requires `ValToEntry` for map types. - * **Arguments:** - * `name = new_setter_name`: Renames the entry subcomponent_model starter method (e.g., `#[ subform_entry( name = command ) ]`). - * `setter = bool`: Enables/disables the entry subcomponent_model starter method. Default: `true`. - * `debug`: Prints a sketch of the generated subform entry setter and `End` struct. - -## Component Model Derives (Related Utilities) - -While the core of this crate is the `#[ derive( Former ) ]` macro, the `component_model` crate (by re-exporting from `component_model_types` and `component_model_meta`) also provides a suite of related derive macros focused on **type-based component access and manipulation**. These are often useful in conjunction with or independently of the main `Former` derive. - -These derives require the corresponding features to be enabled (they are enabled by default). - -* **`#[ derive( Assign ) ]`:** - * Implements the `component_model_types::Assign< FieldType, IntoT >` trait for each field of the struct. - * Allows setting a field based on its **type**, using `.assign( value )` where `value` can be converted into the field's type. - * Requires fields to have unique types within the struct. - * *Example:* `my_struct.assign( 10_i32 ); my_struct.assign( "hello".to_string() );` - -* **`#[ derive( ComponentFrom ) ]`:** - * Implements `std::convert::From< &YourStruct >` for each field's type. - * Allows extracting a field's value based on its **type** using `.into()` or `From::from()`. - * Requires fields to have unique types within the struct. - * *Example:* `let name : String = ( &my_struct ).into();` - -* **`#[ derive( ComponentsAssign ) ]`:** - * Generates a helper trait (e.g., `YourStructComponentsAssign`) with a method (e.g., `.your_struct_assign( &other_struct )`). - * This method assigns values from fields in `other_struct` to fields of the *same type* in `self`. - * Requires `From< &OtherStruct >` to be implemented for each relevant field type. - * Useful for updating a struct from another struct containing a subset or superset of its fields. - * *Example:* `my_struct.your_struct_assign( &source_struct );` - -* **`#[ derive( FromComponents ) ]`:** - * Implements `std::convert::From< T >` for the struct itself, where `T` is some source type. - * Allows constructing the struct *from* a source type `T`, provided `T` implements `Into< FieldType >` for each field in the struct. - * Requires fields to have unique types within the struct. - * *Example:* `let my_struct : YourStruct = source_struct.into();` - -These component derives offer a powerful, type-driven way to handle data mapping and transformation between different struct types.

Codebase is clean and consistent. Metadata is accurate. - ## Notes & Insights * **Decision Point:** The most critical decision is the core terminology (`Former` vs. `ComponentModel` vs. something else).

This maintains the core `FormerField` definition and simpler methods together while improving maintainability of the complex parts. -* **[Date/Increment 1] Insight:** Splitting `component_model_enum.rs` primarily involves extracting the large `generate_implicit_component_model_for_variant` helper function into its own file within an `enum` submodule. This isolates the most complex part of the enum derivation logic. -* **[Date/Increment 1] Requirement:** All file splitting operations (Increments 2 and 4) must maintain semantic equivalence with the original code.

Verification Strategy: Run `cargo check --workspace` and ensure the errors are resolved. ## Notes & Insights - -* *(No notes yet)* -* **[2025-04-29] Skipped Increment:** Increment 5 (Extract handler for Tuple variants with non-zero fields) was skipped due to persistent issues with applying automated changes to `module/core/former_meta/src/derive_former/former_enum.rs`. Manual intervention is required to complete this increment. -* **[2025-04-29] Stuck in Increment 6:** Encountered persistent compilation errors after moving code into `handle_struct_non_zero_variant`. Initiating Stuck Resolution Process. -* **[2025-04-29] Hypotheses for Increment 6:** - * Hypothesis 1: The generated `Storage` struct or its implementations contain a brace mismatch or syntax error. - * Hypothesis 2: The generated `DefinitionTypes` struct or its implementations contain a brace mismatch or syntax error. - * Hypothesis 3: The generated `Definition` struct or its implementations contain a brace mismatch or syntax error. - * Hypothesis 4: The generated `Former` struct contains a brace mismatch or syntax error. -* **[2025-04-30/Increment 14] Verification Failure:** `cargo check --package former_meta` failed due to pre-existing errors in `module/core/former_meta/src/derive_former/former_enum/struct_non_zero.rs`. These errors are unrelated to the changes in Increment 14 and will be addressed in Increment 15. -* **[2025-05-01/Increment 15] Stuck Point:** Encountered persistent compilation errors (E0277: the trait bound `former_enum::EnumVariantHandlerContext<'a>: macro_tools::quote::ToTokens` is not satisfied) when refactoring `handle_struct_non_zero_variant` to use the context struct within `quote!` macros. This indicates an issue with correctly interpolating fields from the context struct. Status: Resolved. -* **[2025-05-02/Increment 15] Analysis:** The error E0277 indicates that `EnumVariantHandlerContext` does not implement `ToTokens`, which is required for direct interpolation in `quote!`. This supports Hypothesis 1 from the Increment 15 hypotheses. -* [Date/Inc 1] Insight: `quote!` macro does not support interpolating paths like `#ctx.enum_name`. A local variable must be used to store the value before interpolation. -* **[2025-05-02/Increment 15] Stuck Point:** Encountered persistent `mismatched types` errors (E0308) related to handling the `WhereClause` obtained from `generic_params::decompose`. The compiler expects `Punctuated` but finds `Option<_>`. Status: Resolved. -* **[2025-05-02/Increment 15] Resolution:** The `mismatched types` error when handling the `WhereClause` was resolved by accessing the `where_clause` directly from `ctx.generics.where_clause` (which is `Option`) and handling the `Option` and predicates from there, instead of using the `Option<&WhereClause>` returned by `generic_params::decompose`. Also fixed a syntax error with an extra brace and a suspicious double reference clone. -* **[2025-05-02/Increment 16] Verification:** Standalone constructor logic verified through successful execution of the test suite (`cargo test --package former --test tests`). Manual inspection via debug output was not possible with current tools. -* **[2025-05-02/Increment 17] Verification:** All clippy warnings and codestyle issues in the `former_enum` module and handlers have been addressed. Documentation comments have been updated. `cargo clippy --package former_meta` passes with only minor warnings outside the scope of the refactoring. Manual review confirms code quality. -* **[2025-05-02/Increment 18] Verification:** Full test suite (`cargo test --package former --test tests`) passes with 233/233 tests successful. Final review confirms the refactoring is complete, correct, and integrated. diff --git a/module/core/program_tools/src/lib.rs b/module/core/program_tools/src/lib.rs index 19f55a0993..d382b6bb58 100644 --- a/module/core/program_tools/src/lib.rs +++ b/module/core/program_tools/src/lib.rs @@ -1,24 +1,18 @@ -// #![ cfg_attr( feature = "no_std", no_std ) ] -#![ doc( html_logo_url = "https://raw.githubusercontent.com/Wandalen/wTools/master/asset/img/logo_v3_trans_square.png" ) ] -#![ doc( html_favicon_url = "https://raw.githubusercontent.com/Wandalen/wTools/alpha/asset/img/logo_v3_trans_square_icon_small_v2.ico" ) ] -#![ doc( html_root_url = "https://docs.rs/program_tools/latest/program_tools/" ) ] -#![ doc = include_str!( concat!( env!( "CARGO_MANIFEST_DIR" ), "/", "Readme.md" ) ) ] - #![ allow( unused_imports, dead_code, missing_docs ) ] // xxx : rid of #[ cfg( feature = "enabled" ) ] -use mod_interface::mod_interface; - -// xxx : move is_cicd here -// println!( "MODULES_PATH : {}", env!( "MODULES_PATH" ) ); -// println!( "WORKSPACE_PATH : {}", env!( "WORKSPACE_PATH" ) ); -// // xxx : add to program_tools::{ path::modules(), path::workspace() } - -#[ cfg( feature = "enabled" ) ] -mod_interface!

Custom defaults can be specified easily with `#[ component_model( default = ... ) ]`. -* **Powerful Collection & Nested Struct Handling:** `component_model` truly shines with its **subcomponent_model** system. Easily build `Vec`, `HashMap`, `HashSet`, and other collections element-by-element, or configure nested structs using their own dedicated component_models within the parent's builder chain.

Search patterns: + * `r#"#\[proc_macro_derive\(\s*FromComponents\s*[,)]"#` + * `r#"#\[proc_macro_derive\(\s*ComponentsAssign\s*[,)]"#` + * `r#"#\[proc_macro_derive\(\s*ComponentAssign\s*[,)]"#` + * `r#"#\[proc_macro_derive\(\s*ComponentFrom\s*[,)]"#` + * Also search for potential attribute macros if derive is not found: `r#"#\[proc_macro_attribute]\s*pub\s+fn\s+(?:from_components|components_assign|...)"#` + * **Detailed Plan Step 2 (Analyze Dependencies):** Read the code surrounding the located macro definitions. Identify any helper functions, structs, or constants defined within `former_meta` that are *exclusively* used by these macros. Trace their usage to ensure they aren't needed elsewhere. + * **Detailed Plan Step 3 (Remove Macro Code):** Use `apply_diff` to precisely remove the entire `#[proc_macro_derive]` function block (or `#[proc_macro_attribute]` function) for each of the four macros. Also, remove the helper code identified in Step 2 if it's confirmed to be exclusively used by the removed macros. Be careful not to remove unrelated code. + * **Detailed Plan Step 4 (Remove Exports):** Check `module/core/former/src/former_meta/src/lib.rs` and any relevant `mod.rs` files (e.g., `module/core/former/src/former_meta/src/derive/mod.rs`) for `pub use` statements exporting the removed macros (e.g., `pub use private::FromComponents;`).

Verify no *new* unrelated errors/warnings were introduced. +* ⚫ **Increment 2:** Remove Derive Usage in `former_types` + * **Detailed Plan Step 1 (Locate Derive Usage):** Use `search_files` within `module/core/former/src/former_types/src` for the regex pattern: `r#"#\[derive\([^)]*(?:FromComponents|ComponentsAssign|ComponentAssign|ComponentFrom)[^)]*\)]"#`. This pattern finds the derives even when mixed with others. + * **Detailed Plan Step 2 (Remove Derive Attributes):** For each file and struct/enum identified in Step 1, use `apply_diff`. The SEARCH block should target the `#[derive(...)]` line, and the REPLACE block should contain the same line but *without* `FromComponents`, `ComponentsAssign`, `ComponentAssign`, or `ComponentFrom`. Ensure other derives on the same line remain untouched. Example: `#[derive( Debug, Clone, FromComponents )]` becomes `#[derive( Debug, Clone )]`. + * **Detailed Plan Step 3 (Analyze Implicit Dependencies):** Search within `module/core/former/src/former_types/src` for code that might rely on traits or methods generated by the removed derives. Search terms: + * Trait bounds: `where T: FromComponents`, `impl FromComponents for ...` (and variants for other derives). + * Potential method calls: `.from_components(`, `.assign_components(`, `.assign_component(`, `.component_from(`. (These are guesses; actual names depend on macro implementation). + * Specific types potentially related only to these derives. + * **Detailed Plan Step 4 (Remove/Refactor Dependent Code):** Based on Step 3 findings, use `apply_diff` to: + * Remove `impl` blocks for the component traits. + * Remove functions or methods whose logic entirely depended on the component model. + * Refactor functions/methods by removing calls to component methods or changing signatures that used related types/traits. + * Remove structs/enums if they become completely unused after removing derives and related logic. + * **Crucial Design Rules:** [Prioritize Reuse and Minimal Change](#prioritize-reuse-and-minimal-change) (Adapt existing code where possible instead of wholesale removal). + * **Verification Strategy:** + * Request user run `cargo build --package former_types`. + * Request user run `cargo clippy --package former_types -- -D warnings`. + * Analyze output critically: Expect successful compilation. Look specifically for errors indicating missing traits, methods, or types that were previously generated or used by the component model.

If functionality relied on the component model: + * Replace component access/assignment with direct field access or standard struct construction/update syntax. + * If a feature was entirely based on the component model, remove the feature's code (functions, structs) after careful analysis confirms it's isolated. + * Adapt function signatures if they used component-specific types. + * **Crucial Design Rules:** [Prioritize Reuse and Minimal Change](#prioritize-reuse-and-minimal-change) (Refactor existing logic before removing features). + * **Verification Strategy:** + * Request user run `cargo build --package former`. + * Request user run `cargo clippy --package former -- -D warnings`. + * Analyze output critically: Expect successful compilation. Focus on errors related to missing derives, types, traits, methods, or functions previously part of the component model implementation or its usage in `former`. Ensure no new unrelated errors/warnings. +* ⚫ **Increment 4:** Clean Up Tests in All Affected Crates + * **Detailed Plan Step 1 (Locate Affected Tests):** Use `search_files` in the following directories: `module/core/former/tests`, `module/core/former/src/former_meta/tests`, `module/core/former/src/former_types/tests`, `module/core/former/src/former/tests`.

Can the test be adapted to test remaining functionality, or should it be removed entirely? + * **Detailed Plan Step 3 (Remove/Modify Tests):** + * For tests solely testing removed features: Use `apply_diff` to remove the entire `#[test]` function or the `mod tests { ... }` block.

Test failures indicate component model usage in tests and examples, requiring these to be addressed within Increment 3. diff --git a/module/core/former/tests/inc/mod.rs b/module/core/former/tests/inc/mod.rs index 0f4920fc91..57c3fc85e5 100644 --- a/module/core/former/tests/inc/mod.rs +++ b/module/core/former/tests/inc/mod.rs @@ -275,53 +275,6 @@ mod former_enum_tests } -#[ cfg( feature = "derive_components" ) ] -mod components_tests -{ - use super::*; - - #[ cfg( feature = "derive_component_from" ) ] - mod component_from_manual; - #[ cfg( feature = "derive_component_from" ) ] - mod component_from; - #[ cfg( feature = "derive_component_from" ) ] - mod component_from_tuple; - #[ cfg( feature = "derive_component_from" ) ] - mod component_from_tuple_manual; - - #[ cfg( feature = "derive_component_assign" ) ] - mod component_assign_manual; - #[ cfg( feature = "derive_component_assign" ) ] - mod component_assign; - #[ cfg( feature = "derive_component_assign" ) ] - mod component_assign_tuple; - #[ cfg( feature = "derive_component_assign" ) ] - mod component_assign_tuple_manual; - - #[ cfg( all( feature = "derive_component_assign", feature = "derive_components_assign" ) ) ] - mod components_assign_manual; - #[ cfg( all( feature = "derive_component_assign", feature = "derive_components_assign" ) ) ] - mod components_assign; - #[ cfg( all( feature = "derive_component_assign", feature = "derive_components_assign" ) ) ] - mod components_assign_tuple; - #[ cfg( all( feature = "derive_component_assign", feature = "derive_components_assign" ) ) ] - mod components_assign_tuple_manual; - - #[ cfg( all( feature = "derive_from_components" ) ) ] - mod from_components_manual; - #[ cfg( all( feature = "derive_from_components" ) ) ] - mod from_components; - #[ cfg( all( feature = "derive_from_components" ) ) ] - mod from_components_tuple; - #[ cfg( all( feature = "derive_from_components" ) ) ] - mod from_components_tuple_manual; - - #[ cfg( all( feature = "derive_component_from", feature = "derive_component_assign", feature = "derive_components_assign", feature = "derive_from_components" ) ) ] - mod composite_manual; - #[ cfg( all( feature = "derive_component_from", feature = "derive_component_assign", feature = "derive_components_assign", feature = "derive_from_components" ) ) ] - mod composite; - -} only_for_terminal_module! { diff --git a/module/core/former_meta/src/component/component_assign.rs b/module/core/former_meta/src/component/component_assign.rs index a9b9776fd2..bca1ef986c 100644 --- a/module/core/former_meta/src/component/component_assign.rs +++ b/module/core/former_meta/src/component/component_assign.rs @@ -12,116 +12,4 @@ use macro_tools:: /// /// Generates implementations of the `Assign` trait for each field of a struct. -/// -pub fn component_assign( input : proc_macro::TokenStream ) -> Result< proc_macro2::TokenStream > -{ - let original_input = input.clone(); - let parsed = syn::parse::< syn::ItemStruct >( input )?; - let has_debug = attr::has_debug( parsed.attrs.iter() )?; - let item_name = &parsed.ident.clone(); - - // Directly iterate over fields and handle named/unnamed cases - let for_fields = match &parsed.fields - { - syn::Fields::Named( fields_named ) => - { - fields_named.named.iter() - .map( | field | for_each_field( field, None, item_name ) ) // Pass None for index - .collect::< Result< Vec< _ > > >()? - }, - syn::Fields::Unnamed( fields_unnamed ) => - { - fields_unnamed.unnamed.iter().enumerate() - .map( |( index, field )| for_each_field( field, Some( index ), item_name ) ) // Pass Some(index) - .collect::< Result< Vec< _ > > >()? - }, - syn::Fields::Unit => - { - // No fields to generate Assign for - vec![] - }, - }; - - let result = qt! - { - #( #for_fields )* - }; - - if has_debug - { - let about = format!( "derive : Assign\nstructure : {item_name}" ); - diag::report_print( about, &original_input, &result ); - } - - Ok( result ) -} - -/// Generates an implementation of the `Assign` trait for a specific field of a struct. -/// -/// This function creates the trait implementation that enables setting a struct's field value -/// with a type that can be converted into the field's type.

The plan has been updated with the correct paths. * **[Date/Inc #] Insight:** Reading `module/core/former_meta/src/component/mod.rs` failed, suggesting the `component` directory might not be a standard module with a `mod.rs` file, or there's an environmental issue. However, the content of the individual files in `component/` and `lib.rs` has been read, allowing analysis of dependencies. -* **[Date/Inc #] Insight:** The removal process requires careful searching and targeted modifications across three crates (`former_meta`, `former_types`, `former`) plus associated tests, docs, and examples. Proceeding increment by increment, focusing on one crate or aspect (like tests) at a time, is crucial to manage complexity. +* **[Date/Inc #] Insight:** The removal process requires careful searching and targeted modifications across three crates (`former_meta`, `former_types`, `former`) plus associated tests, docs, and examples. Proceeding increment by increment, focusing on one crate or aspect (like tests) at a crucial to manage complexity. * **[Date/Inc #] Insight:** Verification after each increment using `cargo build`, `clippy`, and `test` for the specific package(s) modified is essential to catch errors early before they propagate. * **[Date/Inc #] Insight:** Refined final verification steps to explicitly target only `former`, `former_meta`, and `former_types` packages, avoiding workspace-wide commands, per user feedback. * **[Date/Inc 3] Insight:** User requested running `cargo test` instead of `cargo clippy` for Increment 3 verification. Plan updated to reflect this. Test failures indicate component model usage in tests and examples, requiring these to be addressed within Increment 3. diff --git a/module/core/former_meta/Cargo.toml b/module/core/former_meta/Cargo.toml index 0c7a9aae27..3af3918402 100644 --- a/module/core/former_meta/Cargo.toml +++ b/module/core/former_meta/Cargo.toml @@ -32,27 +32,28 @@ proc-macro = true default = [ "enabled", "derive_former", - "derive_components", - "derive_component_from", - "derive_component_assign", - "derive_components_assign", - "derive_from_components", + # "derive_components", + # "derive_component_from", + # "derive_component_assign", + # "derive_components_assign", + # "derive_from_components", ] full = [ "default", ] -enabled = [ "macro_tools/enabled", "iter_tools/enabled", "former_types/enabled" ] +enabled = [ "macro_tools/enabled", "iter_tools/enabled", "former_types/enabled", "component_model_types/enabled" ] derive_former = [ "convert_case" ] -derive_components = [ "derive_component_assign", "derive_components_assign", "derive_component_from", "derive_from_components" ] -derive_component_assign = [] -derive_components_assign = [ "derive_component_assign", "convert_case" ] -derive_component_from = [] -derive_from_components = [] +# derive_components = [ "derive_component_assign", "derive_components_assign", "derive_component_from", "derive_from_components" ] +# derive_component_assign = [] +# derive_components_assign = [ "derive_component_assign", "convert_case" ] +# derive_component_from = [] +# derive_from_components = [] [dependencies] macro_tools = { workspace = true, features = [ "attr", "attr_prop", "ct", "item_struct", "container_kind", "diag", "phantom", "generic_params", "generic_args", "typ", "derive", "ident" ] } # qqq : zzz : optimize set of features -former_types = { workspace = true, features = [ "types_component_assign" ] } +former_types = { workspace = true, features = [] } +component_model_types = { workspace = true, features = [ "types_component_assign" ] } iter_tools = { workspace = true } convert_case = { version = "0.6.0", default-features = false, optional = true, features = [] } diff --git a/module/core/former_meta/src/derive_former/field_attrs.rs b/module/core/former_meta/src/derive_former/field_attrs.rs index 6eea921281..3c6b0d9018 100644 --- a/module/core/former_meta/src/derive_former/field_attrs.rs +++ b/module/core/former_meta/src/derive_former/field_attrs.rs @@ -15,7 +15,7 @@ use macro_tools:: proc_macro2::TokenStream, // Import TokenStream // syn::spanned::Spanned, // No longer needed here };

Search patterns: - * `r#"#\[proc_macro_derive\(\s*FromComponents\s*[,)]"#` - * `r#"#\[proc_macro_derive\(\s*ComponentsAssign\s*[,)]"#` - * `r#"#\[proc_macro_derive\(\s*ComponentAssign\s*[,)]"#` - * `r#"#\[proc_macro_derive\(\s*ComponentFrom\s*[,)]"#` - * Also search for potential attribute macros if derive is not found: `r#"#\[proc_macro_attribute]\s*pub\s+fn\s+(?:from_components|components_assign|...)"#` - * **Detailed Plan Step 2 (Analyze Dependencies):** Read the code surrounding the located macro definitions. Identify any helper functions, structs, or constants defined within `former_meta` that are *exclusively* used by these macros. Trace their usage to ensure they aren't needed elsewhere. - * **Detailed Plan Step 3 (Remove Macro Code):** Use `apply_diff` to precisely remove the entire `#[proc_macro_derive]` function block (or `#[proc_macro_attribute]` function) for each of the four macros. Also, remove the helper code identified in Step 2 if it's confirmed to be exclusively used by the removed macros. Be careful not to remove unrelated code. - * **Detailed Plan Step 4 (Remove Exports):** Check `module/core/former_meta/src/lib.rs` and any relevant `mod.rs` files (e.g., `module/core/former_meta/src/derive/mod.rs`) for `pub use` statements exporting the removed macros (e.g., `pub use private::FromComponents;`). Use `apply_diff` to remove these specific export lines. - * **Crucial Design Rules:** [Structuring: Keep all Definitions and Details Inside `private` namespace](#structuring-keep-all-definitions-and-details-inside-private-namespace) (verify helpers were private if applicable), [Structuring: Explicit Exposure Rule](#structuring-explicit-exposure-rule) (guides removal of exports). - * **Verification Strategy:** - * Request user run `cargo build --package former_meta`. - * Request user run `cargo clippy --package former_meta -- -D warnings`. - * Analyze output critically: Expect successful compilation with no errors or warnings related to the removed macros or helpers. Verify no *new* unrelated errors/warnings were introduced. -* ✅ **Increment 2:** Remove Derive Usage in `former_types` - * **Detailed Plan Step 1 (Locate Derive Usage):** Use `search_files` within `module/core/former/src/former_types/src` for the regex pattern: `r#"#\[derive\([^)]*(?:FromComponents|ComponentsAssign|ComponentAssign|ComponentFrom)[^)]*\)]"#`. This pattern finds the derives even when mixed with others. - * **Detailed Plan Step 2 (Remove Derive Attributes):** For each file and struct/enum identified in Step 1, use `apply_diff`. The SEARCH block should target the `#[derive(...)]` line, and the REPLACE block should contain the same line but *without* `FromComponents`, `ComponentsAssign`, `ComponentAssign`, or `ComponentFrom`. Ensure other derives on the same line remain untouched. Example: `#[derive( Debug, Clone, FromComponents )]` becomes `#[derive( Debug, Clone )]`. - * **Detailed Plan Step 3 (Analyze Implicit Dependencies):** Search within `module/core/former/src/former_types/src` for code that might rely on traits or methods generated by the removed derives. Search terms: - * Trait bounds: `where T: FromComponents`, `impl FromComponents for ...` (and variants for other derives). - * Potential method calls: `.from_components(`, `.assign_components(`, `.assign_component(`, `.component_from(`. (These are guesses; actual names depend on macro implementation). - * Specific types potentially related only to these derives. - * **Detailed Plan Step 4 (Remove/Refactor Dependent Code):** Based on Step 3 findings, use `apply_diff` to: - * Remove `impl` blocks for the component traits. - * Remove functions or methods whose logic entirely depended on the component model. - * Refactor functions/methods by removing calls to component methods or changing signatures that used related types/traits. - * Remove structs/enums if they become completely unused after removing derives and related logic. - * **Crucial Design Rules:** [Prioritize Reuse and Minimal Change](#prioritize-reuse-and-minimal-change) (Adapt existing code where possible instead of wholesale removal). - * **Verification Strategy:** - * Request user run `cargo build --package former_types`. - * Request user run `cargo clippy --package former_types -- -D warnings`. - * Analyze output critically: Expect successful compilation. Look specifically for errors indicating missing traits, methods, or types that were previously generated or used by the component model. Ensure no new unrelated errors/warnings. -* ✅ **Increment 3:** Remove Derive Usage and Related Code in `former` (including tests and examples) - * **Detailed Plan Step 1 (Locate Derive Usage in src):** Use `search_files` within `module/core/former/src/former/src` using the same regex as Increment 2, Step 1: `r#"#\[derive\([^)]*(?:FromComponents|ComponentsAssign|ComponentAssign|ComponentFrom)[^)]*\)]"#`. (Done - None found) - * **Detailed Plan Step 2 (Locate Related Code in src):** Use `search_files` within `module/core/former/src/former/src` for: - * The derive usage pattern from Step 1. - * Explicit imports: `use former_types::.*Component.*`, `use former_meta::FromComponents` (and variants). - * Method calls: `.components(`, `.assign_components_from(`, etc. (as in Inc 2, Step 3). - * Function signatures or struct fields using component-related types from `former_types`. - * Trait bounds or `impl` blocks related to component traits. (Done - None found) - * **Detailed Plan Step 3.1 (Analyze Test Failures):** Analyze `cargo test --package former` output. Identify files/lines in `module/core/former/tests/` causing errors due to missing component model features. (Done) - * **Detailed Plan Step 3.2 (Fix Tests):** Use `apply_diff` to remove/refactor failing test code in `module/core/former/tests/` based on Step 3.1 analysis. (Focus on removing tests for removed features or adapting assertions). (Done - Removed `mod components_tests;`) - * **Detailed Plan Step 3.3 (Analyze Example Failures):** Analyze `cargo test --package former` output. Identify files/lines in `module/core/former/examples/` causing errors. (Done - Identified `former_component_from.rs`) - * **Detailed Plan Step 3.4 (Fix Examples):** Use `apply_diff` or `write_to_file` to remove/refactor failing example code in `module/core/former/examples/` based on Step 3.3 analysis. (Done - Emptied `former_component_from.rs`, then added placeholder `main`) - * **Detailed Plan Step 3.5 (Refactor src Logic):** Analyze code in `module/core/former/src/former/src` surrounding any potential (though unlikely based on searches) removals from previous steps. Refactor if needed. (Done - Checked `lib.rs`, no changes needed) - * **Crucial Design Rules:** [Prioritize Reuse and Minimal Change](#prioritize-reuse-and-minimal-change) (Adapt existing code where possible instead of wholesale removal), [Testing: Avoid Writing Automated Tests Unless Asked](#testing-avoid-writing-tests-unless-asked) (Justifies removing tests for removed features). - * **Verification Strategy:** - * Run `cargo build --package former`. - * Run `cargo test --package former`. - * Analyze output critically: Expect successful compilation and tests passing. Focus on errors related to missing derives, types, traits, methods, or functions previously part of the component model implementation or its usage in `former`. Ensure no new unrelated errors/warnings. -* ✅ **Increment 4:** Clean Up Tests in All Affected Crates (Now potentially smaller scope due to Step 3.2) - * **Detailed Plan Step 1 (Locate Affected Tests):** Use `search_files` in the following directories: `module/core/former/tests`, `module/core/former_meta/tests`, `module/core/former/src/former_types/tests`, `module/core/former/src/former/tests`. Search patterns: - * Derive usage on test structs: `r#"#\[derive\([^)]*(?:FromComponents|ComponentsAssign|ComponentAssign|ComponentFrom)[^)]*\)]"#` - * Component method calls: `.components(`, `.assign_components_from(`, etc. - * Assertions checking component-related state or behavior. - * Keywords: `FromComponents`, `ComponentsAssign`, `ComponentAssign`, `ComponentFrom`. (Done - Only found inactive code in `components_tests` or docs) - * **Detailed Plan Step 2 (Analyze Tests):** For each identified test function or module, determine if its primary purpose was to test the now-removed component functionality. Can the test be adapted to test remaining functionality, or should it be removed entirely? (Done - No active tests found) - * **Detailed Plan Step 3 (Remove/Modify Tests):** - * For tests solely testing removed features: Use `apply_diff` to remove the entire `#[test]` function or the `mod tests { ... }` block. If a whole file (e.g., `tests/component_tests.rs`) becomes empty, propose its removal (e.g., via `write_to_file` with empty content or asking user to delete). - * For tests partially affected: Use `apply_diff` to remove the specific derive usages, method calls, and assertions related to the component model, adapting the test to focus on remaining logic. (Done - No active tests needed modification) - * **Crucial Design Rules:** [Testing: Avoid Writing Automated Tests Unless Asked](#testing-avoid-writing-tests-unless-asked) (Justifies removing tests for removed features). - * **Verification Strategy:** - * Request user run `cargo test --package former_meta --package former_types --package former`. - * Analyze output critically: Ensure no tests fail. Verify that the *total number* of tests executed has decreased compared to the baseline (if known). Check for any new compilation errors within the test code itself. -* ✅ **Increment 5:** Update Documentation (Code & Readmes) - * **Detailed Plan Step 1 (Locate Documentation):** Use `search_files` across: - * Source files: `module/core/former_meta/src/**/*.rs`, `module/core/former/src/former_types/src/**/*.rs`, `module/core/former/src/former/src/**/*.rs` - * Readme: `module/core/former/Readme.md` - * Other potential docs: `module/core/former/docs/**/*.md` (if exists) - * Search keywords: `FromComponents`, `ComponentsAssign`, `ComponentAssign`, `ComponentFrom`, "component model", "components assign", "component from". (Done - Found in `former_meta/src/component/*.rs` (removed), `former/Readme.md`, `former/tests/inc/mod.rs`) - * **Detailed Plan Step 2 (Analyze Documentation):** Review search results in doc comments (`///`, `//!`) and Markdown files. Identify explanations, examples within docs, API references, or conceptual sections related to the removed derives/model. (Done - Identified locations) - * **Detailed Plan Step 3 (Remove/Update Documentation):** Use `apply_diff` to: - * Remove sentences or paragraphs discussing the removed features. - * Remove code examples in docs that used the derives. - * Update surrounding text to ensure logical flow and coherence after removals. - * Remove mentions from API lists or feature summaries. (Done - Removed from `former/Readme.md`) - * **Crucial Design Rules:** [Comments and Documentation](#comments-and-documentation) (Focus on removing outdated info, ensure clarity). - * **Verification Strategy:** - * Request user run `cargo doc --package former_meta --package former_types --package former --no-deps`. Check for warnings (especially broken links). (Done - Passed) - * Recommend manual review by the user of `Readme.md` and key source files with modified doc comments to ensure accuracy and readability. -* ✅ **Increment 6:** Update Examples (Now potentially smaller scope due to Step 3.4) - * **Detailed Plan Step 1 (Locate Examples):** Use `list_files` to check if `module/core/former/examples` exists. If yes, use `search_files` within `module/core/former/examples/*.rs` for the keywords and derive patterns used in previous increments. (Done - Found references in `former_component_from.rs` and potentially others) - * **Detailed Plan Step 2 (Analyze Examples):** Determine if any found examples heavily rely on the removed component model features. Can they be refactored to demonstrate alternative usage, or are they now obsolete? (Done - `former_component_from.rs` is obsolete) - * **Detailed Plan Step 3 (Remove/Modify Examples):** - * If obsolete: Propose removing the example file (e.g., `write_to_file` with empty content or ask user). - * If adaptable: Use `apply_diff` to remove derive usage and component method calls, refactoring the example to use current APIs. (Done - Emptied `former_component_from.rs` content in Inc 3, added placeholder `main`) - * **Crucial Design Rules:** N/A (Focus is removal/adaptation). - * **Verification Strategy:** - * If examples were modified: Request user run `cargo run --example --package former` (or relevant crate). Check for compilation errors and verify expected output (if any). - * If examples were removed: Request user run `cargo build --examples --package former` (or relevant crate) to ensure the examples build process doesn't fail. -* ⏳ **Increment 7:** Final Package Verification - * **Detailed Plan Step 1 (Final Sweep):** Perform a final `search_files` across the target directories (`module/core/former_meta`, `module/core/former/src/former_types`, `module/core/former/src/former`, `module/core/former/tests`, `module/core/former/examples`, `module/core/former/docs`) for any remaining occurrences of `FromComponents`, `ComponentsAssign`, `ComponentAssign`, `ComponentFrom` to catch any missed references. - * **Detailed Plan Step 2 (Final Cleanup):** If Step 1 finds anything, use `apply_diff` or `write_to_file` to remove the final remnants within the affected crate's files. - * **Detailed Plan Step 3 (Comprehensive Checks - Targeted):** Request user run the following commands sequentially: - * `cargo check --package former_meta --package former_types --package former --all-targets` - * `cargo clippy --package former_meta --package former_types --package former --all-targets -- -D warnings` - * `cargo test --package former_meta --package former_types --package former --all-targets` - * **Crucial Design Rules:** N/A. - * **Verification Strategy:** Analyze the output of *all* commands in Step 3 critically. The goal is zero errors and zero warnings across all specified packages (`former_meta`, `former_types`, `former`) and targets. Confirm all remaining tests within these packages pass. +* [⚫] **Increment 1:** Uncomment Main Test Modules & Get Baseline + * **Detailed Plan Step 1:** Modify `module/core/former/tests/inc/mod.rs`.

Also, `read_file` and `list_files` failed for paths within this directory, contradicting "VSCode Open Tabs". Status: Resolved (Root cause identified as incorrect paths in plan). -* **[Date/Inc #] Struggling Point:** Unable to remove the content of `module/core/former_meta/src/component/component_from.rs` using `write_to_file`. Status: Resolved (Used `apply_diff` successfully). -* **[Date/Inc #] Struggling Point:** Unable to remove component-specific traits and impls from `module/core/former_meta/src/lib.rs` using `apply_diff` due to content mismatch including documentation comments. Status: Resolved (Identified need to include comments in search). -* **[Date/Inc #] Struggling Point:** Unable to remove component-specific traits and impls from `module/core/former_meta/src/lib.rs` using `apply_diff` due to incorrect line numbering after previous edits. This issue is repeating. Status: Resolved (Realized these were documentation examples, not macro code). -* **[Date/Inc #] Struggling Point:** Unable to remove the content of `module/core/former/examples/former_component_from.rs` using `write_to_file`. Status: Resolved (Used `apply_diff` successfully). -* **[Date/Inc #] Hypothesis Test:** Hypothesis: The component model code is in `module/core/former_meta/src/component/*.rs` but uses different macro definitions/naming. Test: Read the content of these specific files. **Result:** Rejected. **Reasoning:** `read_file` failed for `from_components.rs`, and `list_files` found no files in the directory, indicating the path or tool is not working as expected for this location. -* **[Date/Inc #] Hypothesis Test:** Hypothesis: The files listed in "VSCode Open Tabs" within `module/core/former_meta/src/` are the correct paths, and the previous tool failures were transient or specific path issues. Test: Attempt to read `module/core/former_meta/src/lib.rs`. **Result:** Rejected. **Reasoning:** `read_file` failed for `lib.rs`. -* **[Date/Inc #] Hypothesis Test:** Hypothesis: `apply_diff` can be used as a fallback to remove the content of `module/core/former_meta/src/component/component_from.rs`. Test: Attempt to remove content using `apply_diff`. **Result:** Confirmed. **Reasoning:** The `apply_diff` operation was successful in removing the file content. -* **[Date/Inc #] Hypothesis Test:** Hypothesis: The `apply_diff` tool is highly sensitive to exact content matches, and removing blocks individually with meticulously copied content from the latest `read_file` result might succeed. Test: Attempt to remove the `BigOptsComponentsAssign` trait block from `module/core/former_meta/src/lib.rs` using `apply_diff` with content copied directly from the last successful `read_file` result. **Result:** Rejected. **Reasoning:** The `apply_diff` failed due to content mismatch, indicating the search content (copied from the previous read) did not exactly match the file content, likely due to documentation comments. -* **[Date/Inc #] Hypothesis Test:** Hypothesis: The `apply_diff` tool requires the search content to exactly match the file content, including documentation comments. I need to read the file again and meticulously copy the *entire* block, including the leading `///` comments, for the `apply_diff` to succeed. Test: Read `module/core/former_meta/src/lib.rs` again. Then, use the correct line numbers and the exact content (including documentation comments) from the new `read_file` result in `apply_diff` calls to remove the `BigOptsComponentsAssign` trait block using `apply_diff`, ensuring the SEARCH block includes the documentation comments exactly as they appear in the file. **Result:** Confirmed. **Reasoning:** Including the documentation comments in the search content allowed the `apply_diff` to succeed. -* **[Date/Inc #] Hypothesis Test:** Hypothesis: The line numbers for the `SmallerOptsComponentsAssign` blocks in `module/core/former_meta/src/lib.rs` have shifted due to the removal of the `BigOptsComponentsAssign` blocks. I need to get the current content of the file to determine the correct starting line numbers for the remaining blocks I want to remove. Test: Read `module/core/former_meta/src/lib.rs` again to get the updated line numbering. Then, use the correct line numbers and the exact content (including documentation comments) from the new `read_file` result in `apply_diff` calls to remove the `SmallerOptsComponentsAssign` trait and its impl block individually. **Result:** Inconclusive (Test not yet performed). **Reasoning:** Need to perform the read and the subsequent `apply_diff` attempts with the updated line numbers. -* **[Date/Inc #] Hypothesis Test:** Hypothesis: `apply_diff` can be used as a fallback to remove the content of `module/core/former/examples/former_component_from.rs` where `write_to_file` failed. Test: Attempt to remove content using `apply_diff`. **Result:** Confirmed. **Reasoning:** The `apply_diff` operation was successful in removing the file content. -* **[Date/Inc #] Insight:** The initial recursive file listing of the workspace revealed that the `former_meta` crate is located at `module/core/former_meta/`, not nested under `module/core/former/src/`. The paths in the plan for `former_meta` were incorrect, causing all file operations targeting that crate to fail. The plan has been updated with the correct paths. -* **[Date/Inc #] Insight:** Reading `module/core/former_meta/src/component/mod.rs` failed, suggesting the `component` directory might not be a standard module with a `mod.rs` file, or there's an environmental issue. However, the content of the individual files in `component/` and `lib.rs` has been read, allowing analysis of dependencies. -* **[Date/Inc #] Insight:** The removal process requires careful searching and targeted modifications across three crates (`former_meta`, `former_types`, `former`) plus associated tests, docs, and examples. Proceeding increment by increment, focusing on one crate or aspect (like tests) at a crucial to manage complexity. -* **[Date/Inc #] Insight:** Verification after each increment using `cargo build`, `clippy`, and `test` for the specific package(s) modified is essential to catch errors early before they propagate. -* **[Date/Inc #] Insight:** Refined final verification steps to explicitly target only `former`, `former_meta`, and `former_types` packages, avoiding workspace-wide commands, per user feedback. -* **[Date/Inc 3] Insight:** User requested running `cargo test` instead of `cargo clippy` for Increment 3 verification. Plan updated to reflect this. Test failures indicate component model usage in tests and examples, requiring these to be addressed within Increment 3. +* **[Date/Inc #] Insight:** The `components_tests` module and its contents will be ignored as the component model is being removed per the other plan (`plan.md`). +* **[Date/Inc #] Insight:** The task for `parametrized_dyn_manual.rs` seems complex and has its own plan (`plan_dyn_trait_issue.md`).

If a task is complex, convert it into a standard `// TODO:` comment with a brief explanation or suggest creating a dedicated issue. * **Component Model Exclusion:** Do *not* uncomment or attempt to fix tests within `module/core/former/tests/inc/components_tests/`. This module should remain inactive or be deleted as per the component model removal plan (`plan.md`). * **Minimal Changes:** Prioritize fixing existing tests with minimal changes.

Prioritize these rules over the existing style in the repository if conflicts arise. -* **Paired Testing (Proc Macro Rule):** Ensure derived macro output (`_derive` tests) is always tested alongside its intended manual equivalent (`_manual` tests) within the same increment. The `_only_test` files, if present, should also be uncommented in the same increment as they often contain shared code, but they are not run directly. This verifies the macro's correctness against a known baseline. -* **Incremental Verification:** After each increment involving uncommenting a group of test files and making code changes: - * Ensure the relevant code compiles (`cargo check --tests --package former`). - * Run all active tests within the enum test module (`cargo test --package former -- former_enum_tests`). Critically analyze any failures, focusing on the newly added tests (`_derive` and `_manual` variants) while ensuring previously passing tests remain successful. -* **Task Handling:** Address `// xxx :` and `// qqq :` comments found in the currently uncommented test code. If a task is complex, convert it into a standard `// TODO:` comment with a brief explanation or suggest creating a dedicated issue. -* **Component Model Exclusion:** Do *not* uncomment or attempt to fix tests within `module/core/former/tests/inc/components_tests/`. This module should remain inactive or be deleted as per the component model removal plan (`plan.md`). -* **Minimal Changes:** Prioritize fixing existing tests with minimal changes.

This module should remain inactive or be deleted as per the component model removal plan (`plan.md`). +* **Minimal Changes:** Prioritize fixing existing tests with minimal changes, adhering to the [Minimal Changes](#enhancements-only-implement-whats-requested) rule. Avoid unnecessary refactoring unless required to make the test pass or adhere to rules. +* **Plan Persistence:** Any modification to this plan (status updates, adding notes, refining steps) **must** be immediately persisted to `module/core/former/plan.md` using the `write_to_file` tool, and user confirmation of the successful write must be received before proceeding. +* **Approval Gates:** Explicit user approval **must** be obtained before starting implementation of an increment (after detailed planning is finalized and written) and after successful verification of an increment (before moving to the next). User confirmation of successful `write_to_file` operations is also required. +* **Context Generation:** This plan assumes a `context.md` file has been generated (via `generate_context.sh` planned and executed in prior steps) based on the files and crates listed in the `## Context` section. This `context.md` will be used during implementation. ## Notes & Insights From 75a9363c8fae0355a42b5479f9e80c0033a4902d Mon Sep 17 00:00:00 2001 From: wandalen Date: Sun, 4 May 2025 15:55:23 +0300 Subject: [PATCH 099/235] plan --- module/core/former/plan.md | 187 ++++++++++++++-------------- module/core/former/tests/inc/mod.rs | 4 +- 2 files changed, 96 insertions(+), 95 deletions(-) diff --git a/module/core/former/plan.md b/module/core/former/plan.md index 373442ed95..c95e08f09c 100644 --- a/module/core/former/plan.md +++ b/module/core/former/plan.md @@ -2,7 +2,7 @@ ## Goal -* Uncomment the `former_enum_tests` module and then incrementally uncomment **groups of related test files** (typically `_derive`, `_manual`, `_only_test` variants for a feature) within `module/core/former/tests/inc/former_enum_tests/`.

Does the *intended* logic in the uncommented `_derive.rs`, `_manual.rs`, and `_only_test.rs` files align with this expectation? If there was a pre-analysis discrepancy noted, start there. +2. **Analyze Error:** Examine the compiler error or test panic message provided by the user. + * **Compile Error in `_derive.rs`:** Likely a macro generation issue (`former_meta`) or a fundamental incompatibility between the enum structure and the "Expected Enum Former Behavior". + * **Compile Error in `_manual.rs`:** Likely an error in the manual implementation itself, or a mismatch with the shared `_only_test.rs` logic or the "Expected Enum Former Behavior". + * **Compile Error in `_only_test.rs`:** Likely an issue with the test logic itself, inconsistent naming/types between `_derive.rs` and `_manual.rs`, or a mismatch with the "Expected Enum Former Behavior". + * **Test Panic/Failure in `_derive.rs`:** The macro generates code that compiles but produces runtime behavior inconsistent with `_only_test.rs` or the "Expected Enum Former Behavior". + * **Test Panic/Failure in `_manual.rs`:** The manual implementation has runtime behavior inconsistent with `_only_test.rs` or the "Expected Enum Former Behavior". + +3. **Check `_manual.rs` Test:** Does the `_manual` test pass independently? + * **If YES:** The manual implementation aligns with `_only_test.rs`. The issue is likely in the macro (`former_meta`) or the `_derive.rs` setup *not matching the manual implementation or the expected behavior*. Proceed to Step 4. + * **If NO:** The issue is likely in the manual implementation (`_manual.rs`) or the shared test logic (`_only_test.rs`). + * Review `_manual.rs` against the "Expected Enum Former Behavior" rules and the logic in `_only_test.rs`.

Re-run all tests for the module. If still failing, re-evaluate the "Expected Enum Former Behavior" and the test logic. + * **If NO:** (And `_manual` passed) The issue is almost certainly in the macro implementation (`former_meta`) generating code that is inconsistent with the working `_manual.rs` and the "Expected Enum Former Behavior". + * **Compare Generated Code:** Request the user to help capture the macro-generated code. Compare this generated code side-by-side with the *working* `_manual.rs` implementation. Identify discrepancies. + * **Propose Macro Fix:** Based on the comparison and the "Expected Enum Former Behavior", propose specific changes to the relevant handler function within `former_meta` to make the generated code match the manual implementation's logic and the expected behavior. + +5. **Verify Behavior Model:** Ensure the final proposed fix results in behavior consistent with the "Expected Enum Former Behavior" rules.

Does the *intended* logic in the uncommented `_derive.rs`, `_manual.rs`, and `_only_test.rs` files align with this expectation? If there was a pre-analysis discrepancy noted, start there. +2. **Analyze Error:** Examine the compiler error or test panic message provided by the user. + * **Compile Error in `_derive.rs`:** Likely a macro generation issue (`former_meta`) or a fundamental incompatibility between the enum structure and the "Expected Enum Former Behavior". + * **Compile Error in `_manual.rs`:** Likely an error in the manual implementation itself, or a mismatch with the shared `_only_test.rs` logic or the "Expected Enum Former Behavior". + * **Compile Error in `_only_test.rs`:** Likely an issue with the test logic itself, inconsistent naming/types between `_derive.rs` and `_manual.rs`, or a mismatch with the "Expected Enum Former Behavior". + * **Test Panic/Failure in `_derive.rs`:** The macro generates code that compiles but produces runtime behavior inconsistent with `_only_test.rs` or the "Expected Enum Former Behavior". + * **Test Panic/Failure in `_manual.rs`:** The manual implementation has runtime behavior inconsistent with `_only_test.rs` or the "Expected Enum Former Behavior". + +3. **Check `_manual.rs` Test:** Does the `_manual` test pass independently? + * **If YES:** The manual implementation aligns with `_only_test.rs`. The issue is likely in the macro (`former_meta`) or the `_derive.rs` setup *not matching the manual implementation or the expected behavior*. Proceed to Step 4. + * **If NO:** The issue is likely in the manual implementation (`_manual.rs`) or the shared test logic (`_only_test.rs`). + * Review `_manual.rs` against the "Expected Enum Former Behavior" rules and the logic in `_only_test.rs`. Propose fixes to `_manual.rs` or `_only_test.rs` to align them with the expected behavior. + +4. **Check `_derive.rs` Test:** Does the `_derive` test pass independently? + * **If YES:** (And `_manual` also passed) The issue might be subtle or related to interactions not covered by individual tests. Re-run all tests for the module. If still failing, re-evaluate the "Expected Enum Former Behavior" and the test logic. + * **If NO:** (And `_manual` passed) The issue is almost certainly in the macro implementation (`former_meta`) generating code that is inconsistent with the working `_manual.rs` and the "Expected Enum Former Behavior". + * **Compare Generated Code:** Request the user to help capture the macro-generated code. Compare this generated code side-by-side with the *working* `_manual.rs` implementation. Identify discrepancies. + * **Propose Macro Fix:** Based on the comparison and the "Expected Enum Former Behavior", propose specific changes to the relevant handler function within `former_meta` to make the generated code match the manual implementation's logic and the expected behavior. + +5. **Verify Behavior Model:** Ensure the final proposed fix results in behavior consistent with the "Expected Enum Former Behavior" rules. If the rules themselves seem incorrect based on the investigation, note this discrepancy and seek clarification. + +6. **Prioritize Recent Changes:** Always consider the code changes made in the current or immediately preceding steps (uncommenting files, applying previous fixes) as the most likely cause of new failures. + +## Increments + +* [✅] **Increment 1:** Uncomment `former_enum_tests` Module Declaration + * ...

If there was a pre-analysis discrepancy noted, start there. -2. **Analyze Error:** Examine the compiler error or test panic message provided by the user. - * **Compile Error in `_derive.rs`:** Likely a macro generation issue (`former_meta`) or a fundamental incompatibility between the enum structure and the "Expected Enum Former Behavior". - * **Compile Error in `_manual.rs`:** Likely an error in the manual implementation itself, or a mismatch with the shared `_only_test.rs` logic or the "Expected Enum Former Behavior". - * **Compile Error in `_only_test.rs`:** Likely an issue with the test logic itself, inconsistent naming/types between `_derive.rs` and `_manual.rs`, or a mismatch with the "Expected Enum Former Behavior". - * **Test Panic/Failure in `_derive.rs`:** The macro generates code that compiles but produces runtime behavior inconsistent with `_only_test.rs` or the "Expected Enum Former Behavior". - * **Test Panic/Failure in `_manual.rs`:** The manual implementation has runtime behavior inconsistent with `_only_test.rs` or the "Expected Enum Former Behavior". - -3. **Check `_manual.rs` Test:** Does the `_manual` test pass independently? - * **If YES:** The manual implementation aligns with `_only_test.rs`. The issue is likely in the macro (`former_meta`) or the `_derive.rs` setup *not matching the manual implementation or the expected behavior*. Proceed to Step 4. - * **If NO:** The issue is likely in the manual implementation (`_manual.rs`) or the shared test logic (`_only_test.rs`). - * Review `_manual.rs` against the "Expected Enum Former Behavior" rules and the logic in `_only_test.rs`. Propose fixes to `_manual.rs` or `_only_test.rs` to align them with the expected behavior. - -4. **Check `_derive.rs` Test:** Does the `_derive` test pass independently? - * **If YES:** (And `_manual` also passed) The issue might be subtle or related to interactions not covered by individual tests. Re-run all tests for the module. If still failing, re-evaluate the "Expected Enum Former Behavior" and the test logic. - * **If NO:** (And `_manual` passed) The issue is almost certainly in the macro implementation (`former_meta`) generating code that is inconsistent with the working `_manual.rs` and the "Expected Enum Former Behavior". - * **Compare Generated Code:** Request the user to help capture the macro-generated code. Compare this generated code side-by-side with the *working* `_manual.rs` implementation. Identify discrepancies. - * **Propose Macro Fix:** Based on the comparison and the "Expected Enum Former Behavior", propose specific changes to the relevant handler function within `former_meta` to make the generated code match the manual implementation's logic and the expected behavior. - -5. **Verify Behavior Model:** Ensure the final proposed fix results in behavior consistent with the "Expected Enum Former Behavior" rules. If the rules themselves seem incorrect based on the investigation, note this discrepancy and seek clarification. - -6. **Prioritize Recent Changes:** Always consider the code changes made in the current or immediately preceding steps (uncommenting files, applying previous fixes) as the most likely cause of new failures. - ## Increments +* ⚫ Increment 1: Run `cargo check` and `cargo test` in `module/core/former`, analyze warnings, and fix them iteratively. + * Detailed Plan Step 1: Execute `cargo check` in `module/core/former` to get the initial list of warnings. + * Detailed Plan Step 2: Execute `cargo test --lib` in `module/core/former` to get any additional warnings reported by tests. + * Detailed Plan Step 3: Analyze the combined output, identify the first warning. + * Detailed Plan Step 4: Propose and apply code changes to fix the warning, adhering to codestyle and design rules. + * Detailed Plan Step 5: Repeat steps 3-4 for each subsequent warning until no warnings are reported by either `cargo check` or `cargo test --lib`. + * Verification Strategy: Run `cargo check` and `cargo test --lib` in `module/core/former` after each fix or group of fixes to confirm the warning is resolved and no new warnings or errors are introduced. + +## Requirements +* Fix all warnings reported by `cargo check` and `cargo test --lib` in the `former` crate. +* Do not uncomment or modify the commented-out tests unless a warning specifically relates to them. + ## Notes & Insights diff --git a/module/core/former/tests/inc/former_enum_tests/enum_named_fields_manual.rs b/module/core/former/tests/inc/former_enum_tests/enum_named_fields_manual.rs index 638eb8a046..aeb3645f92 100644 --- a/module/core/former/tests/inc/former_enum_tests/enum_named_fields_manual.rs +++ b/module/core/former/tests/inc/former_enum_tests/enum_named_fields_manual.rs @@ -49,7 +49,7 @@ where Definition: FormerDefinition { #[inline(always)] pub fn begin(storage: Option, context: Option, on_end: Definition::End) -> Self { Self { storage: storage.unwrap_or_default(), context, on_end: Some(on_end) } } - #[inline(always)] pub fn new(on_end: Definition::End) -> Self { Self::begin(None, None, on_end) } + #[inline(always)] pub fn _new(on_end: Definition::End) -> Self { Self::begin(None, None, on_end) } #[inline] pub fn value(mut self, src: impl Into) -> Self { self.storage.value = Some(src.into()); self } } // --- End Manual Former for InnerForSubform --- @@ -64,7 +64,7 @@ pub enum EnumWithNamedFields // Renamed enum for clarity UnitVariantDefault, // Renamed VariantZeroScalar {}, - VariantZeroDefault {}, // Error case - no manual impl needed + // VariantZeroDefault {}, // Error case - no manual impl needed VariantZeroUnnamedScalar(), // New VariantZeroUnnamedDefault(), // New diff --git a/module/core/former_meta/src/derive_former/former_enum/struct_non_zero.rs b/module/core/former_meta/src/derive_former/former_enum/struct_non_zero.rs index 9357507324..1c4d904e15 100644 --- a/module/core/former_meta/src/derive_former/former_enum/struct_non_zero.rs +++ b/module/core/former_meta/src/derive_former/former_enum/struct_non_zero.rs @@ -1,29 +1,19 @@ // File: module/core/former_meta/src/derive_former/former_enum/struct_non_zero.rs use super::*; // Use items from parent module (former_enum) -use syn::token::{ Const, Colon }; use macro_tools:: { generic_params, Result, - quote::{ format_ident, quote }, + quote::{ format_ident }, ident, - parse_quote, - punctuated, // Import punctuated utilities }; use syn:: { self, Fields, - Error, GenericParam, - TypeParam, - ConstParam, - LifetimeParam, - GenericArgument, - Expr, punctuated::Punctuated, token::Comma, - WherePredicate, // Import WherePredicate }; use convert_case::{ Case, Casing }; @@ -38,29 +28,29 @@ pub( super ) fn handle_struct_non_zero_variant let variant = &ctx.variant; let variant_ident = &variant.ident; let variant_attrs = &ctx.variant_attrs; - let struct_attrs = &ctx.struct_attrs; + let _struct_attrs = &ctx.struct_attrs; let generics = &ctx.generics; let variant_field_info = &ctx.variant_field_info; - let vis = &ctx.vis; - let enum_name = &ctx.enum_name; + let _vis = &ctx.vis; + let _enum_name = &ctx.enum_name; // Define field_types here to make it available in multiple scopes - let field_types : Vec = variant_field_info.iter().map( |f_info| f_info.ty.clone() ).collect(); // Collect owned types + let _field_types : Vec = variant_field_info.iter().map( |f_info| f_info.ty.clone() ).collect(); // Collect owned types // Generate the snake_case method name, handling potential keywords let variant_name_str = variant_ident.to_string(); let method_name_snake_str = variant_name_str.to_case( Case::Snake ); // Use format_ident!

Full error reporting will be part of the subsequent implementation plan. -* The `EnumVariantHandlerContext` and `EnumVariantFieldInfo` structs (and potentially `ItemAttributes`, `FieldAttributes` if they were local to the old `former_enum.rs`) will need to be defined or correctly imported within the new `former_enum.rs`. -* **[5/7/2025] Struggling Point:** Unresolved import errors after deleting old handler files. Cannot determine correct paths for `derive_tools_meta::derive` despite enabling features. - Status: Unresolved \ No newline at end of file +* This plan focuses specifically on unit variants. +* The "Test Matrix for Unit Variants" will be embedded in `former_enum_tests/mod.rs` for persistence. +* The "Expected Enum Former Behavior Rules" are simplified for unit variants.

No test logic changes or uncommenting of actual tests within the files being moved, unless necessary to fix paths after moving. +* **Preserve Docs & Comments:** Existing documentation in `former_enum_tests/mod.rs` (like test matrices) should be preserved. All test code, including currently commented-out tests, must be preserved in its new location(s). +* **File Splitting:** Files testing multiple variant types *must* be split. +* **Incremental Verification:** Verify `cargo check` after each major step. * **Approval Gates:** Obtain user approval before starting each increment and after successful verification. ## Notes & Insights -* This plan focuses on tuple enum variants, activating tests incrementally. -* It assumes the necessary infrastructure (`former_enum_tests/mod.rs`) exists. -* Verification steps target only the relevant tuple tests until the final step. -* The full "Expected Enum Former Behavior Rules" are kept for context. -* Test Matrix coverage for tuple variants is explicitly noted and will be added to `mod.rs`. -* `cargo clippy` check is excluded. -* Verification strategy updated to test `_manual` before `_derive`. -* Widespread failure handling strategy refined to be selective. -* Relevant context expanded to include core crate files and documentation, with an emphasis on pre-reading. +* This plan focuses on a structural refactoring to improve organization before tackling test logic. +* The splitting of mixed-aspect files is a key part of this refactoring. +* The actual uncommenting and fixing of tests within these new subdirectories will be handled by subsequent, focused plans. +* The `mod.rs` files within the new subdirectories (`unit_tests/mod.rs`, etc.) will initially have their `mod` declarations for individual test files commented out.

This module aggregates various test suites for the `former` crate and its associated derive macros. -//! Below is an outline of the features tested and their corresponding test modules within this directory. -//! -//! ## Feature Coverage Outline: -//! -//! - **Former Derive for Structs** -//! - **Basic Functionality:** -//! - Simple struct definition and forming -//! - Primitive types -//! - Optional types -//! - Tuple structs -//! - User-defined types (with Default, without Default, without Debug) -//! - Unsigned primitive types -//! - **Collections Handling:** -//! - Basic scalar setters for collections -//! - Standard collections (Vec, HashMap, HashSet, BTreeMap, BTreeSet, LinkedList, BinaryHeap) -//! - Collection interface traits -//! - **Subform Setters:** -//! - `#[subform_collection]` (implicit, explicit definition, named, custom, setter on/off) -//! - `#[subform_entry]` (implicit, manual, named, setter on/off, HashMap specific) -//! - `#[subform_scalar]` (implicit, manual, named) -//! - Combinations of subform attributes on a single field -//! - **Attributes:** -//! - **Struct-level:** -//! - `#[storage_fields]` -//! - `#[mutator(custom)]` -//! - `#[perform]` -//! - **Field-level:** -//! - `#[former(default = ...)]` -//! - `#[scalar(name = ..., setter = ..., debug)]` -//! - `#[subform_collection(name = ..., setter = ..., debug, definition = ...)]` -//! - `#[subform_entry(name = ..., setter = ..., debug)]` -//! - `#[subform_scalar(name = ..., setter = ..., debug)]` -//! - Multiple attributes on one field -//! - Feature-gated fields (`#[cfg(...)]`) -//! - **Generics & Lifetimes:** -//! - Parametrized struct -//! - Parametrized field -//! - Slice lifetimes -//! - Dyn traits -//! - **Edge Cases:** -//! - Keyword identifiers for fields -//! - Keyword identifiers for subform setters -//! - Name collisions (with std types, keywords, etc.) -//! - Visibility (public/private structs and fields) -//! - **Compile-time Failures:** Tests ensuring incorrect usage results in compile errors. -//! -//! - **Former Derive for Enums** -//! - Basic setup (manual vs derived) -//! - Unit variants -//! - Tuple variants: -//! - Single field (scalar vs subform default behavior) -//! - Multi-field (scalar only, error for default subform) -//! - Named-field (struct-like) variants -//! - Variant attributes (`#[scalar]`, `#[subform_scalar]`) -//! - Edge cases (keywords as variant names) -//! -//! - **Component Derives** -//! - `#[derive(ComponentFrom)]` -//! - `#[derive(Assign)]` -//! - `#[derive(ComponentsAssign)]` -//! - `#[derive(FromComponents)]` -//! - Composite usage (using multiple component derives together) -//! - Tuple struct support for component derives -//! - Manual vs Derived comparison tests -//! - Compile-time Failures (placeholder/needs expansion) -//! -//! - **General Tests** -//! - Basic smoke tests (local and published) -//!

Functionality:** +//! - Simple struct definition and forming +//! - Primitive types +//! - Optional types +//! - Tuple structs +//! - User-defined types (with Default, without Default, without Debug) +//! - Unsigned primitive types +//! - **Collections Handling:** +//! - Basic scalar setters for collections +//! - Standard collections (Vec, HashMap, HashSet, BTreeMap, BTreeSet, LinkedList, BinaryHeap) +//! - Collection interface traits +//! - **Subform Setters:** +//! - `#[subform_collection]` (implicit, explicit definition, named, custom, setter on/off) +//! - `#[subform_entry]` (implicit, manual, named, setter on/off, HashMap specific) +//! - `#[subform_scalar]` (implicit, manual, named) +//! - Combinations of subform attributes on a single field +//! - **Attributes:** +//! - **Struct-level:** +//! - `#[storage_fields]` +//! - `#[mutator(custom)]` +//! - `#[perform]` +//! - **Field-level:** +//! - `#[former(default = ...)]` +//! - `#[scalar(name = ..., setter = ..., debug)]` +//! - `#[subform_collection(name = ..., setter = ..., debug, definition = ...)]` +//! - `#[subform_entry(name = ..., setter = ..., debug)]` +//! - `#[subform_scalar(name = ..., setter = ..., debug)]` +//! - Multiple attributes on one field +//! - Feature-gated fields (`#[cfg(...)]`) +//! - **Generics & Lifetimes:** +//! - Parametrized struct +//! - Parametrized field +//! - Slice lifetimes +//! - Dyn traits +//! - **Edge Cases:** +//! - Keyword identifiers for fields +//! - Keyword identifiers for subform setters +//! - Name collisions (with std types, keywords, etc.) +//! - Visibility (public/private structs and fields) +//! - **Compile-time Failures:** Tests ensuring incorrect usage results in compile errors. + +use super::*; +use test_tools::exposed::*; + +use

Project Plan: Audit and Finalize Single-Aspect Focus for Enum Tests ## Goal -* Reorganize the `module/core/former/tests/inc/former_enum_tests/` directory by creating three subdirectories: - * `unit_tests/` - * `unnamed_tests/` (for tuple variants) - * `named_tests/` (for struct-like variants with named fields) -* Move existing enum test files into the appropriate new subdirectory. -* **If an existing test file covers multiple variant types (unit, tuple, named), it must be split into separate files, each focusing on a single variant type, and then moved to the correct subdirectory.** -* Update `module/core/former/tests/inc/former_enum_tests/mod.rs` and newly created subdirectory `mod.rs` files to reflect the new structure, ensuring all `mod` declarations point to the correct new paths. -* Ensure all tests (even if internally commented out in their final locations) compile after the refactoring. The primary goal is structural integrity; test logic verification is for subsequent plans. -* Preserve all existing test logic, including any currently commented-out tests (they will remain commented out in their new locations). +* Audit all test files within the `module/core/former/tests/inc/former_enum_tests/` subdirectories (`unit_tests/`, `unnamed_tests/`, `named_tests/`, `complex_tests/`, and their respective `compile_fail/` subdirectories if they exist). +* Verify that each test file (`_derive.rs`, `_manual.rs`, `_only_test.rs`, or standalone `.rs`) within `unit_tests/`, `unnamed_tests/`, and `named_tests/` strictly focuses on a single enum variant aspect: Unit, Unnamed (tuple), or Named (struct-like) variants, respectively. +* If any file is found to still cover multiple aspects (an oversight from the previous restructuring), it **must be split** into separate files. Each new file will be dedicated to a single aspect and placed in (or moved to) the correct subdirectory. +* Files within the `complex_tests/` directory will be reviewed. If they can be reasonably refactored to fit into the single-aspect categories, a plan for that will be proposed and executed. Otherwise, they will remain in `complex_tests/`. +* Update `mod.rs` files within each subdirectory accurately. Module declarations for individual test files will remain **commented out**. +* Ensure the `former` package compiles without errors or warnings after refactoring (`cargo check --package former --tests`). +* Ensure `cargo test --package former --test tests` passes (acknowledging that specific enum tests within the refactored area will not run due to commented-out module declarations). +* Preserve all existing test logic. If a test file, after moving/splitting, causes a persistent compilation error (not related to paths), the specific failing test function or its module declaration will be commented out to allow structural verification to proceed. ## Relevant Context -* **Primary Directory to Refactor:** `module/core/former/tests/inc/former_enum_tests/` -* **Module File to Update:** `module/core/former/tests/inc/former_enum_tests/mod.rs` -* **Parent Module File:** `module/core/former/tests/inc/mod.rs` -* **Existing Test Files within `former_enum_tests/`:** (Full list will be generated in Increment 1) - * Includes `_derive.rs`, `_manual.rs`, `_only_test.rs` patterns, and single files like `usecase1.rs`. - * Includes the `compile_fail/` directory. -* **Documentation:** - * `module/core/former/advanced.md` +**Important:** Before starting implementation, thoroughly review the `Readme.md` and `advanced.md` files for the `former` crate, and the `Readme.md` for `former_meta` to ensure a full understanding of the existing design, features, and intended behaviors. + +* **Primary Directories to Audit (Post-Restructuring):** + * `module/core/former/tests/inc/former_enum_tests/unit_tests/` + * `module/core/former/tests/inc/former_enum_tests/unnamed_tests/` + * `module/core/former/tests/inc/former_enum_tests/named_tests/` + * `module/core/former/tests/inc/former_enum_tests/complex_tests/` + * Respective `compile_fail/` subdirectories within each of the above (e.g., `unit_tests/compile_fail/`). +* **Module Files to Update:** + * `module/core/former/tests/inc/former_enum_tests/unit_tests/mod.rs` + * `module/core/former/tests/inc/former_enum_tests/unnamed_tests/mod.rs` + * `module/core/former/tests/inc/former_enum_tests/named_tests/mod.rs` + * `module/core/former/tests/inc/former_enum_tests/complex_tests/mod.rs` + * `module/core/former/tests/inc/former_enum_tests/mod.rs` (for top-level submodule declarations) + * (And `mod.rs` files within `compile_fail` subdirectories if applicable) +* **Core Crate Files (for context on macro behavior):** + * `module/core/former/src/lib.rs` + * `module/core/former_meta/src/lib.rs` + * `module/core/former_meta/src/derive_former/former_enum.rs` (and its submodules like `unit_variant_handler.rs`, etc.) + * `module/core/former_types/src/lib.rs` +* **Documentation (for context on features and attributes):** * `module/core/former/Readme.md` - -### Expected Enum Former Behavior Rules (Full Set for Context) - -(This section will be preserved as it's crucial for understanding the purpose of the tests being moved, even if not directly acted upon in *this* refactoring plan.) -1. **`#[scalar]` Attribute (on variant):** ... -2. **`#[subform_scalar]` Attribute (on variant):** ... -3. **Default Behavior (No `#[scalar]` or `#[subform_scalar]` on variant):** ... -4. **`#[standalone_constructors]` Attribute (on enum):** ... + * `module/core/former/advanced.md` + * `module/core/former_meta/Readme.md` +* **Assumption:** The previous plan (restructuring `former_enum_tests` into `unit_tests/`, `unnamed_tests/`, `named_tests/`, and `complex_tests/` subdirectories) has been successfully executed. + + +## Expected Enum Former Behavior + +This plan adheres to the following rules for `#[derive(Former)]` on enums: + +1. **`#[scalar]` Attribute:** + * **Unit Variant:** Generates `Enum::variant() -> Enum`.

A detailed listing and analysis of each file's content is needed to determine the correct categorization and identify files requiring splitting. Compile-fail tests also need categorization. - * **Crucial Design Rules:** Structuring: Organize by Feature or Layer, Structuring: Add Module Declaration Before Content, Structuring: Split Large Files Methodically (If Requested), Comments: Focus on Rationale, Preserve Existing Tasks, Comments: Add Tasks and Label Simplifications, Comments: Annotate Addressed Tasks. - * **Relevant Behavior Rules:** Expected Enum Former Behavior Rules (referenced for context on test purpose). - * **Detailed Plan Step 1:** Listed all files and subdirectories currently in `module/core/former/tests/inc/former_enum_tests/`. (Completed) - * **Detailed Plan Step 2 (Categorization & Splitting Strategy):** Analyzed each file to identify variant types and plan splitting/relocation.

Re-enable tests incrementally. ## Increments -* [✅] **Increment 1: Audit Plan for Single-Aspect Focus** - * **Goal:** For each test file in its *current* subdirectory (`unit_tests`, `unnamed_tests`, `named_tests`, `complex_tests`, and their `compile_fail` subdirs), verify if it truly adheres to a single aspect. Plan splits for any multi-aspect files. - * **Target Crate(s)::** `former` (planning only) - * **Detailed Plan Step 1 (List Current Structure):** List all files within each subdirectory of `module/core/former/tests/inc/former_enum_tests/`. - * **Detailed Plan Step 2 (Audit and Splitting Strategy):** - * **For `unit_tests/`:** Review each file. If it contains non-unit variant tests, plan to move those parts to new files in `../unnamed_tests/` or `../named_tests/`. The file in `unit_tests/` must be reduced to only unit-specific content. - * **For `unnamed_tests/`:** Review each file. If it contains unit or named variant tests, plan to move those parts to new files in `../unit_tests/` or `../named_tests/`. The file in `unnamed_tests/` must be reduced to only tuple-specific content. - * **For `named_tests/`:** Review each file. If it contains unit or tuple variant tests, plan to move those parts to new files in `../unit_tests/` or `../unnamed_tests/`. The file in `named_tests/` must be reduced to only named-specific content. - * **For `complex_tests/`:** Review each file. If a test can be clearly refactored into a single aspect (unit, unnamed, named) without losing its core testing purpose, plan to split/move it. If it genuinely tests complex_tests interactions not fitting a single category, it remains. - * **For `compile_fail/` subdirectories:** Ensure tests within (e.g., `unnamed_tests/compile_fail/`) are specific to that aspect. If not, plan to move them. - * **Shared `_only_test.rs` files:** If an `_only_test.rs` file serves a `_derive.rs` or `_manual.rs` file that is being split, the `_only_test.rs` file must also be split, or its `include!` directives in the newly split consumer files must be carefully adjusted to only pull relevant test functions. - * **Detailed Plan Step 3 (Output):** Present a list of files to be split, detailing how they will be split and where the new resulting files will be located. List files that are confirmed to be single-aspect and correctly located. - * **Verification Strategy:** User reviews the audit results and the proposed splitting/relocation plan. - * **Commit Message:** `docs(former): Plan for single-aspect audit and refinement of enum tests` - * **Notes:** Completed audit of `unit_tests/`, `unnamed_tests/`, `named_tests/`, and `complex_tests/` within the *expected* `former_enum_tests/` subdirectory. Found that all these directories are currently empty. The test files expected to be in these directories are likely located elsewhere.

The subsequent increments will be revised to operate on these actual directories. - -* [✅] **Increment 2: Audit and Plan Splits/Moves for Enum Test Files in Actual Directories** - * **Goal:** For each test file in its *current* subdirectory (`enum_unit_tests`, `enum_unnamed_tests`, `enum_named_tests`, `enum_complex_tests`, and their `compile_fail` subdirs), verify if it truly adheres to a single aspect. Plan splits for any multi-aspect files and plan moves for files in the wrong category directory. - * **Target Crate(s)::** `former` (planning only) - * **Detailed Plan Step 1 (List Current Structure):** (Already completed in previous steps, found files in `enum_unit_tests/`, `enum_unnamed_tests/`, `enum_named_tests/`, `enum_complex_tests/`). - * **Detailed Plan Step 2 (Audit and Splitting/Moving Strategy):** - * **For `enum_unit_tests/`:** Review each file.

If a test can be clearly refactored into a single aspect (unit, unnamed, named) without losing its core testing purpose, plan to split/move it to the respective single-aspect directory. If it genuinely tests complex interactions not fitting a single category, it remains. - * **For `compile_fail/` subdirectories:** Ensure tests within (e.g., `unnamed_tests/compile_fail/`) are specific to that aspect. If not, plan to move them. - * **Shared `_only_test.rs` files:** If an `_only_test.rs` file serves a `_derive.rs` or `_manual.rs` file that is being split, the `_only_test.rs` file must also be split, or its `include!` directives in the newly split consumer files must be carefully adjusted to only pull relevant test functions. - * **Detailed Plan Step 3 (Output):** Present a list of files to be split, detailing how they will be split and where the new resulting files will be located.

Files covering multiple aspects must be split and/or moved. Files in `enum_complex_tests/` should be confirmed as genuinely complex_tests or refactored. -* **Preserve Logic:** All existing test code (including commented-out tests) must be preserved. If a test causes persistent compilation errors after moving/splitting (not path-related), the specific failing test function or its `mod` declaration in the subdirectory `mod.rs` should be commented out to allow structural verification to proceed. -* **Module Declarations:** All `mod` declarations for individual test files within `enum_unit_tests/mod.rs`, `enum_unnamed_tests/mod.rs`, `enum_named_tests/mod.rs`, and `enum_complex_tests/mod.rs` should remain **commented out**. -* **Incremental Verification:** `cargo check --package former --tests` should pass after each increment. -* **Approval Gates:** Obtain user approval for plans and after each increment. +* **Focus:** Only uncomment and address code related to **unit enum variants**. +* **Incremental Activation:** Uncomment test modules (`mod ...;`) within `unit_tests/mod.rs` one group at a time. +* **Incremental Verification:** Verify compilation and test success after each relevant increment. Verify `_manual` tests before `_derive` tests. Handle widespread failures by selectively commenting out only failing tests. +* **Failure Analysis:** Follow the "Failure Diagnosis Algorithm". +* **Approval Gates:** Obtain user approval before starting each increment and after successful verification. ## Notes & Insights -* This plan is revised based on the actual location of enum test files found in `tests/inc/enum_unit_tests/`, `tests/inc/enum_unnamed_tests/`, `tests/inc/enum_named_tests/`, and `tests/inc/enum_complex_tests/`. -* The primary focus is ensuring each categorized test file *now* strictly adheres to a single aspect. -* The `enum_complex_tests/` directory is for tests that genuinely cannot be broken down without losing their intent. -* This plan sets a clean foundation for subsequent, focused plans to uncomment and verify tests within these well-defined categories. -* The `compile_fail` tests also need to be audited and reorganized. -* The strategy for handling problematic tests during this structural phase is to comment them out selectively to ensure `cargo check` can pass for the overall structure. -* `cargo clippy` and workspace-wide test/check commands are avoided. -* **Update after Increment 1:** The target directories (`unit_tests/`, `unnamed_tests/`, `named_tests/`, `complex_tests/`) within the *expected* `former_enum_tests/` subdirectory were found to be empty. The test files expected to be in these directories are likely located elsewhere. Found actual enum test files in `tests/inc/enum_unit_tests/`, `tests/inc/enum_unnamed_tests/`, `tests/inc/enum_named_tests/`, and `tests/inc/enum_complex_tests/`. The subsequent increments will be revised to operate on these actual directories. -* **Update after Increment 2:** Completed audit of all enum test files. Identified files needing moving, splitting/cleanup, correction, or refinement. Proposed a detailed plan for file operations in Increments 3 and 4, and noted necessary updates to `mod.rs` files in Increment 5 and corrections/refinements in Increment 6. -* **Update after Increment 3:** Successfully moved `tuple_zero_fields` files to `enum_unnamed_tests/`. `cargo check --package former --tests` passed with warnings. Increment 3 is complete. -* **Update after Increment 4:** Successfully split and cleaned up `standalone_constructor_args_tuple_manual.rs` and `standalone_constructor_args_named_manual.rs`. Deleted the original files. `cargo check --package former --tests` passed with warnings. Increment 4 is complete. Changes were manually committed due to a git issue. - * **Update after Increment 5:** Completed updates to all specified `mod.rs` files. Addressed all warnings reported by `cargo check --package former --tests`. Increment 5 is complete. - * **Update after Increment 6:** Corrected `usecase1_manual.rs` to contain the manual former implementation for `FunctionStep`. `cargo check --package former --tests` passed successfully. +* This plan focuses exclusively on unit enum variants. +* The previous restructuring and audit are assumed complete. +* The "Expected Enum Former Behavior Rules" section is now more comprehensive. +* `cargo clippy` is excluded. +* \ No newline at end of file From 292a2d37330c594929e36180a84c5070b3deed26 Mon Sep 17 00:00:00 2001 From: wandalen Date: Sat, 10 May 2025 14:45:57 +0300 Subject: [PATCH 170/235] feat(former): Verify basic unit enum variant functionality --- module/core/former/plan.md | 111 ++++++++++-------- .../former/tests/inc/enum_unit_tests/mod.rs | 6 +- .../enum_unit_tests/unit_variant_derive.rs | 2 +- .../enum_unit_tests/unit_variant_only_test.rs | 16 +-- 4 files changed, 77 insertions(+), 58 deletions(-) diff --git a/module/core/former/plan.md b/module/core/former/plan.md index ba11cc1be5..234c76586b 100644 --- a/module/core/former/plan.md +++ b/module/core/former/plan.md @@ -1,7 +1,7 @@ # Project Plan: Verify and Fix Unit Enum Variant Tests ## Goal -* Systematically uncomment and verify all tests within the `module/core/former/tests/inc/former_enum_tests/unit_tests/` directory. +* Systematically uncomment and verify all tests within the `module/core/former/tests/inc/enum_unit_tests/` directory. * Ensure the `#[derive(Former)]` macro correctly generates the expected constructors for **unit enum variants** (`enum E { UnitVariant }`) according to the "Expected Enum Former Behavior Rules". * Verify the implementation correctly handles `#[scalar]` (which is the default for unit variants) and `#[standalone_constructors]` attributes for unit variants. * Fix any bugs found in the macro (`former_meta`) or test logic (`_manual.rs`, `_derive.rs`, `_only_test.rs`) to ensure all unit variant tests pass. @@ -13,12 +13,26 @@ **Important:** Before starting implementation, thoroughly review the `Readme.md` and `advanced.md` files for the `former` crate, and the `Readme.md` for `former_meta` to ensure a full understanding of the existing design, features, and intended behaviors. -* **Primary Test Directory:** `module/core/former/tests/inc/former_enum_tests/unit_tests/` -

(Handled by: `handle_unit_variant`) + * **Zero-Field Variant (Tuple) (Rule 1b):** Generates `Enum::variant() -> Enum`. (Handled by: `handle_tuple_zero_variant`) + * **Zero-Field Variant (Struct) (Rule 1c):** Generates `Enum::variant() -> Enum`. (Handled by: `handle_struct_zero_variant`) + * **Single-Field Variant (Tuple) (Rule 1d):** Generates `Enum::variant(InnerType) -> Enum`. (Handled by: `handle_tuple_non_zero_variant`) + * **Single-Field Variant (Struct) (Rule 1e):** Generates `Enum::variant { field: InnerType } -> Enum`. (Handled by: `handle_struct_non_zero_variant`) + * **Multi-Field Variant (Tuple) (Rule 1f):** Generates `Enum::variant(T1, T2, ...) -> Enum`. (Handled by: `handle_tuple_non_zero_variant`) + * **Multi-Field Variant (Struct) (Rule 1g):** Generates `Enum::variant { f1: T1, f2: T2, ... } -> Enum`. (Handled by: `handle_struct_non_zero_variant`) + * **Error Cases:** Cannot be combined with `#[subform_scalar]`. + +2. **`#[subform_scalar]` Attribute:** + * **Unit Variant (Rule 2a):** Error. (Checked in: `handle_unit_variant`) + * **Zero-Field Variant (Tuple or Struct) (Rule 2b, 2c):** Error. (Checked in: `handle_tuple_zero_variant`, `handle_struct_zero_variant`) + * **Single-Field Variant (Tuple) (Rule 2d):** Generates `Enum::variant() -> InnerFormer<...>` (where `InnerFormer` is the former for the field's type). Requires the field type to be a path type deriving `Former`. (Handled by: `handle_tuple_non_zero_variant`) + * **Single-Field Variant (Struct) (Rule 2e):** Generates `Enum::variant() -> VariantFormer<...>` (an implicit former for the variant itself). (Handled by: `handle_struct_non_zero_variant`) + * **Multi-Field Variant (Tuple) (Rule 2f):** Error. Cannot use `subform_scalar` on multi-field tuple variants. (Checked in: `handle_tuple_non_zero_variant`) + * **Multi-Field Variant (Struct) (Rule 2g):** Generates `Enum::variant() -> VariantFormer<...>` (an implicit former for the variant itself). (Handled by: `handle_struct_non_zero_variant`) + +3. **Default Behavior (No Attribute):** + * **Unit Variant (Rule 3a):** Generates `Enum::variant() -> Enum`. (Handled by: `handle_unit_variant`) + * **Zero-Field Variant (Tuple) (Rule 3b):** Generates `Enum::variant() -> Enum`. (Handled by: `handle_tuple_zero_variant`) + * **Zero-Field Variant (Struct) (Rule 3c):** Error. Requires `#[scalar]`. (Checked in: `handle_struct_zero_variant`) + * **Single-Field Variant (Tuple) (Rule 3d):** Generates `Enum::variant() -> InnerFormer<...>` (where `InnerFormer` is the former for the field's type). Requires the field type to be a path type deriving `Former`. (Handled by: `handle_tuple_non_zero_variant`) + * **Single-Field Variant (Struct) (Rule 3e):** Generates `Enum::variant() -> VariantFormer<...>` (an implicit former for the variant itself). (Handled by: `handle_struct_non_zero_variant`) + * **Multi-Field Variant (Tuple) (Rule 3f):** Generates `Enum::variant(Field1Type, Field2Type, ...) -> Enum` (behaves like `#[scalar]`). (Handled by: `handle_tuple_non_zero_variant`) + * **Multi-Field Variant (Struct) (Rule 3g):** Generates `Enum::variant() -> VariantFormer<...>` (an implicit former for the variant itself). (Handled by: `handle_struct_non_zero_variant`) + +4. **`#[standalone_constructors]` Attribute (Body Level) (Rule 4):** + * **Rule 4a:** Generates top-level constructor functions for each variant (e.g., `my_variant()`). + * **Rule 4b (Option 2 Logic):** Return type depends on `#[arg_for_constructor]` on fields within the variant. + +### Example of Expected Documentation Comments + +This section shows an example of the documentation comments that will be added to a test file. The content should adhere to the criteria outlined in the `### Requirements` section under "Comment Content". + +**For a file like `module/core/former/tests/inc/enum_unit_tests/generics_in_tuple_variant_unit_derive.rs`:** +```rust +//! Purpose: Tests the `#[derive(Former)]` macro's generation of constructors for unit variants +//! within an enum that has generic parameters and bounds. This file focuses on verifying +//! the derive-based implementation. +//! +//! Coverage: +//! - Rule 3a (Unit + Default): Verifies `Enum::variant() -> Enum` for a generic enum. +//! - Rule 1a (Unit + `#[scalar]`): Verifies `Enum::variant() -> Enum` (as default for unit is scalar) for a generic enum. +//! - (Implicitly) Rule 4a: If `#[standalone_constructors]` were active on `EnumOuter`, this test would also cover +//! the generation of `fn other_variant() -> EnumOuter`. +//! +//! Test Relevance/Acceptance Criteria: +//! - Defines a generic enum `EnumOuter` with a unit variant `OtherVariant`. +//! - Instantiates `EnumOuter` with a concrete type `MyType` that fulfills the `Copy` bound. +//! - Invokes the derived static method `EnumOuter::::other_variant()`. +//! - Asserts that the `got` instance is equal to an `expected` instance, which is manually +//! constructed as `EnumOuter::::OtherVariant`. This confirms the constructor produces the correct variant instance. +``` ## Increments -* [✅] **Increment 1: Activate and Verify `unit_variant_*` Test Group** - * **Goal:** Uncomment and ensure `unit_variant_derive.rs`, `unit_variant_manual.rs`, and `unit_variant_only_test.rs` pass, covering basic unit variants with and without `#[standalone_constructors]`. - * **Target Crate(s):** `former`, `former_meta` - * **Detailed Plan Step 1:** Modify `module/core/former/tests/inc/enum_unit_tests/mod.rs`: - * Uncomment `mod unit_variant_manual;`. - * Uncomment `mod unit_variant_only_test;`. - * **Detailed Plan Step 2 (Manual Verification):** - * **Pre-Analysis:** `unit_variant_manual.rs` should implement `Status::pending()`, `Status::complete()`, and standalone `pending()`, `complete()` all returning `Status`.

Verify `_manual` tests before `_derive` tests. Handle widespread failures by selectively commenting out only failing tests. -* **Failure Analysis:** Follow the "Failure Diagnosis Algorithm". -* **Approval Gates:** Obtain user approval before starting each increment and after successful verification. +* **Adherence:** Strictly follow `code/gen` instructions, Design Rules, and Codestyle Rules for all modifications. +* **Comment Content:** Each targeted test file **must** have the following three `//!` (file-level doc comments) added at the very beginning, before any `use` statements or code, in the specified order: + 1. **`//! Purpose: ...`**: + * Start with "Purpose:". + * Clearly and concisely describe the main goal of the test file. What specific aspect of the `Former` derive macro's behavior for enums is this file intended to verify? + * Mention the specific enum variant structure(s) (e.g., "unit variants", "single-field tuple variants with generics", "multi-field named struct variants") and any key attributes (e.g., `#[scalar]`, `#[subform_scalar]`, `#[standalone_constructors]`) being tested in this file. + * State whether the file is for `derive` macro testing, `manual` implementation testing, or `shared test logic` (`_only_test.rs`). + * For `compile_fail` tests, clearly state the specific incorrect usage or error condition it's designed to trigger and verify, referencing the relevant behavior rule that is being intentionally violated. + * **For `_only_test.rs` files:** The purpose should state that it provides shared test assertions/logic for both derived and manual implementations of [specific feature/variant type]. + 2. **`//! Coverage: ...`**: + * Start with "Coverage:". + * List the specific Rule IDs (e.g., "Rule 1a", "Rule 3d.i") from the "Expected Enum Former Behavior Rules" section that the tests in this file primarily demonstrate or validate. + * Briefly explain *what aspect* of the rule is being tested if the rule is broad and the test is specific (e.g., "Rule 4b - specifically the 'returns Former' case for standalone constructors with partial args"). + * If a test covers interactions between multiple rules (e.g., a variant attribute combined with an enum-level attribute), list all relevant rules and briefly note the interaction. + * **For `_only_test.rs` files:** This comment should summarize all rules covered by the test functions within it, which are then applied to both `_derive.rs` and `_manual.rs` files that include it. + 3. **`//! Test Relevance/Acceptance Criteria: ...`**: + * Start with "Test Relevance/Acceptance Criteria:". + * Describe the key actions performed by the test code and the primary assertions made that validate its stated purpose and coverage. This should explain *how* the test verifies the intended behavior. + * Be specific about the test's mechanics: + * What specific enum structures or attributes are defined/used in this test? + * What specific generated/manual methods are invoked (e.g., `MyEnum::variant_x()`, `former.field_y()`, standalone `variant_z()`)? + * What are the key inputs provided to these methods? + * What is the nature of the primary assertion (e.g., "Asserts the `got` instance (produced by the former) is equal to an `expected` instance (manually constructed to represent the correct state).", "Asserts that a subformer is returned and can be used to set inner fields.", "Asserts that a compile-time error occurs for an invalid attribute combination using `trybuild`."). + * **For `_derive.rs` files:** Mention that it relies on `#[derive(Former)]` for code generation and typically includes shared test logic via `include!("...")`. + * **For `_manual.rs` files:** Mention that it contains a hand-written former implementation and includes shared test logic via `include!("...")`. + * **For `_only_test.rs` files:** Describe the nature of the test functions it contains (e.g., "Defines test functions like `check_variant_construction()` which take a formed enum and assert specific properties/equality. These are designed for reuse by `_derive` and `_manual` tests."). + * **For `compile_fail/*.rs` files:** The file contains code that intentionally uses an attribute or enum structure in a way that violates a documented behavior rule (e.g., `#[subform_scalar]` on a unit variant). The test is accepted if `trybuild` confirms this results in a compilation error, thereby validating the macro's error reporting for this specific invalid scenario." +* **Comment Style:** All added `//!` comments should be clear, concise, grammatically correct, and follow Rust documentation comment conventions. Use Markdown for lists or emphasis if it enhances readability. Aim for reasonable line lengths. +* **Pre-Analysis Output:** Before proposing comments for an increment, the AI must provide its pre-analysis findings for the targeted file(s) as specified in the "Increment Template". +* **Incremental Processing:** Modify files one increment at a time, following the "Increment Template." +* **Verification:** After each increment, request user to apply changes and run `cargo check --package former --tests`. **The code must compile successfully after adding comments. If adding comments introduces a compilation error (e.g., a syntax error in the comment itself), that specific error must be fixed. Pre-existing test failures or logic errors are out of scope.** +* **No Functional Changes:** This task is purely for documentation and review. No functional code changes should be made to the tests or macro logic unless a comment itself causes a trivial syntax issue that prevents compilation. +* **Handling `xxx`/`qqq` Comments:** During the review of each test file, if any existing `// xxx :` or `// qqq :` comments are encountered, their presence and a brief summary of their content should be noted in the "Notes & Insights" section of the `plan.md` for that increment. Addressing or resolving these comments is out of scope for this plan. +* **`mod.rs` Files Review:** If, during the review of test files, it's discovered that an enum test file exists in the directories but is not declared in its respective `mod.rs` file, this should be noted in the "Notes & Insights" for that increment. Activating it is out of scope. ## Notes & Insights -* This plan focuses exclusively on unit enum variants. -* The previous restructuring and audit are assumed complete. -* The "Expected Enum Former Behavior Rules" section is now more comprehensive. -* `cargo clippy` is excluded. -* \ No newline at end of file +* This plan focuses exclusively on documenting existing enum tests by adding comments.

Does the *intended* logic in the uncommented `_derive.rs`, `_manual.rs`, and `_only_test.rs` files align with this expectation? If there was a pre-analysis discrepancy noted, start there. -2. **Analyze Error:** Examine the compiler error or test panic message provided by the user. - * **Compile Error in `_derive.rs`:** Likely a macro generation issue (`former_meta`) or a fundamental incompatibility between the enum structure and the "Expected Enum Former Behavior". - * **Compile Error in `_manual.rs`:** Likely an error in the manual implementation itself, or a mismatch with the shared `_only_test.rs` logic or the "Expected Enum Former Behavior". - * **Compile Error in `_only_test.rs`:** Likely an issue with the test logic itself, inconsistent naming/types between `_derive.rs` and `_manual.rs`, or a mismatch with the "Expected Enum Former Behavior". - * **Test Panic/Failure in `_derive.rs`:** The macro generates code that compiles but produces runtime behavior inconsistent with `_only_test.rs` or the "Expected Enum Former Behavior". - * **Test Panic/Failure in `_manual.rs`:** The manual implementation has runtime behavior inconsistent with `_only_test.rs` or the "Expected Enum Former Behavior". - -3. **Check `_manual.rs` Test:** Does the `_manual` test pass independently? - * **If YES:** The manual implementation aligns with `_only_test.rs`. The issue is likely in the macro (`former_meta`) or the `_derive.rs` setup *not matching the manual implementation or the expected behavior*. Proceed to Step 4. - * **If NO:** The issue is likely in the manual implementation (`_manual.rs`) or the shared test logic (`_only_test.rs`). - * Review `_manual.rs` against the "Expected Enum Former Behavior" rules and the logic in `_only_test.rs`. Propose fixes to `_manual.rs` or `_only_test.rs` to align them with the expected behavior. - -4. **Check `_derive.rs` Test:** Does the `_derive` test pass independently? - * **If YES:** (And `_manual` also passed) The issue might be subtle or related to interactions not covered by individual tests. Re-run all tests for the module. If still failing, re-evaluate the "Expected Enum Former Behavior" and the test logic. - * **If NO:** (And `_manual` passed) The issue is almost certainly in the macro implementation (`former_meta`) generating code that is inconsistent with the working `_manual.rs` and the "Expected Enum Former Behavior". - * **Compare Generated Code:** Request the user to help capture the macro-generated code. Compare this generated code side-by-side with the *working* `_manual.rs` implementation. Identify discrepancies. - * **Propose Macro Fix:** Based on the comparison and the "Expected Enum Former Behavior", propose specific changes to the relevant handler function within `former_meta` to make the generated code match the manual implementation's logic and the expected behavior. - -5. **Verify Behavior Model:** Ensure the final proposed fix results in behavior consistent with the "Expected Enum Former Behavior" rules. If the rules themselves seem incorrect based on the investigation, note this discrepancy and seek clarification. - -6. **Prioritize Recent Changes:** Always consider the code changes made in the current or immediately preceding steps (uncommenting files, applying previous fixes) as the most likely cause of new failures. - -## Increments - -* [✅] **Increment 1:** Uncomment `former_enum_tests` Module Declaration - * ...

Fix macro panics/syntax errors if they occur. - * **Detailed Plan Step 6 (Multi-Field Named Variants):** - * Uncomment `VariantTwoScalar { ... }`. - * **Pre-Analysis:** Expect direct constructor (Rule 1g). Handler: `struct_non_zero.rs`. - * **Verification:** Run `cargo check --tests --package former`. Expect success. Analyze `#[debug]` output. Fix macro panics/syntax errors if they occur. - * **Detailed Plan Step 7 (Enable Runtime Tests):** - * Uncomment the `include!( "enum_named_fields_only_test.rs" );` line in `enum_named_fields_derive.rs`. - * **Verification:** Run `cargo test --package former --test tests -- --test-threads=1 --nocapture former_enum_tests::enum_named_fields`. Expect all tests within this module to pass. Fix any E0599 or runtime logic errors by adjusting the macro code generation based on previous analysis. - * **Detailed Plan Step 8 (Enable Manual Tests):** - * Modify `module/core/former/tests/inc/mod.rs`. Uncomment `mod enum_named_fields_manual;`. - * **Verification:** Run `cargo test --package former --test tests -- --test-threads=1 --nocapture former_enum_tests::enum_named_fields`.

Prioritize these rules over the existing style in the repository if conflicts arise. -* **Detailed Increment Plan:** Before starting implementation of an increment (Step 4 of the workflow), a detailed plan for *that increment only* must be generated and approved. This plan must include: - * Specific file modifications planned (uncommenting modules, addressing tasks). - * **Pre-Analysis:** Statement of the "Expected Enum Former Behavior" for the variant/attribute combination being tested, and a brief analysis of the existing code (`_derive`, `_manual`, `_only_test`) against this expectation *before* running tests. - * Code snippets to be added or changed (if applicable, e.g., uncommenting, fixing tasks). - * Identification of any `xxx`/`qqq` tasks to be addressed. - * References to crucial Design Rules or "Expected Enum Former Behavior" rules. - * The exact verification commands to be run (`cargo check`, `cargo test`). - * The expected outcome of the verification (e.g., "compilation success", "tests X, Y, Z pass and align with expected behavior"). -* **Paired Testing (Proc Macro Rule):** Ensure derived macro output (`_derive` tests) is always tested alongside its intended manual equivalent (`_manual` tests) within the same increment, following the [Proc Macro: Development Workflow](#proc-macro-development-workflow) rule. The `_only_test` files, if present, should also be uncommented in the same increment. **Increments must handle the `_derive`, `_manual`, and `_only_test` files for a feature together.** -* **Incremental Verification:** After each increment involving uncommenting a group of test files and making code changes: - * Ensure the relevant code compiles (`cargo check --tests --package former`). - * Run all active tests within the enum test module (`cargo test --package former --test tests -- --test-threads=1 --nocapture former_enum_tests`). **Analyze logs critically**, focusing on the newly added tests (`_derive` and `_manual` variants) while ensuring previously passing tests remain successful. -* **Failure Analysis:** Before proposing fixes for failing tests, explicitly follow the "Failure Diagnosis Algorithm" defined above, incorporating the pre-analysis step. -* **Task Handling:** Address `// xxx :` and `// qqq :` comments found in the currently uncommented test code according to the [Comments: Add Tasks and Label Simplifications](#comments-add-tasks-and-label-simplifications) rule. If a task is complex, convert it into a standard `// TODO:` comment with a brief explanation or suggest creating a dedicated issue. -* **Component Model Exclusion:** Do *not* uncomment or attempt to fix tests within `module/core/former/tests/inc/components_tests/`. This module should remain inactive or be deleted as per the component model removal plan (`plan.md`). -* **Minimal Changes:** Prioritize fixing existing tests with minimal changes, adhering to the [Minimal Changes](#enhancements-only-implement-whats-requested) rule. Avoid unnecessary refactoring unless required to make the test pass or adhere to rules. -* **Plan Persistence:** Any modification to this plan (status updates, adding notes, refining steps) **must** be immediately persisted to `module/core/former/plan.md` using the `write_to_file` tool, and user confirmation of the successful write must be received before proceeding. -* **Approval Gates:** Explicit user approval **must** be obtained before starting implementation of an increment (after detailed planning is finalized and written) and after successful verification of an increment (before moving to the next). User confirmation of successful `write_to_file` operations is also required. -* **Context Generation:** This plan assumes a `context.md` file has been generated (via `generate_context.sh` planned and executed in prior steps) based on the files and crates listed in the `## Context` section.

Requirements +* **Adherence:** Strictly follow `code/gen` instructions, Design Rules, and Codestyle Rules for all modifications. +* **Comment Content:** Each targeted test file **must** have the following three `//!` (file-level doc comments) added at the very beginning, before any `use` statements or code, in the specified order: + 1. **`//! Purpose: ...`**: + * Start with "Purpose:". + * Clearly and concisely describe the main goal of the test file. What specific aspect of the `Former` derive macro's behavior for enums is this file intended to verify? + * Mention the specific enum variant structure(s) (e.g., "unit variants", "single-field tuple variants with generics", "multi-field named struct variants") and any key attributes (e.g., `#[scalar]`, `#[subform_scalar]`, `#[standalone_constructors]`) being tested in this file. + * State whether the file is for `derive` macro testing, `manual` implementation testing, or `shared test logic` (`_only_test.rs`). + * For `compile_fail` tests, clearly state the specific incorrect usage or error condition it's designed to trigger and verify, referencing the relevant behavior rule that is being intentionally violated. + * **For `_only_test.rs` files:** The purpose should state that it provides shared test assertions/logic for both derived and manual implementations of [specific feature/variant type]. + 2. **`//! Coverage: ...`**: + * Start with "Coverage:". + * List the specific Rule IDs (e.e., "Rule 1a", "Rule 3d.i") from the "Expected Enum Former Behavior Rules" section that the tests in this file primarily demonstrate or validate. + * Briefly explain *what aspect* of the rule is being tested if the rule is broad and the test is specific (e.g., "Rule 4b - specifically the 'returns Former' case for standalone constructors with partial args"). + * If a test covers interactions between multiple rules (e.g., a variant attribute combined with an enum-level attribute), list all relevant rules and briefly note the interaction. + * **For `_only_test.rs` files:** This comment should summarize all rules covered by the test functions within it, which are then applied to both `_derive.rs` and `_manual.rs` files that include it. + 3. **`//! Test Relevance/Acceptance Criteria: ...`**: + * Start with "Test Relevance/Acceptance Criteria:". + * Describe the key actions performed by the test code and the primary assertions made that validate its stated purpose and coverage. This should explain *how* the test verifies the intended behavior. + * Be specific about the test's mechanics: + * What specific enum structures or attributes are defined/used in this test? + * What specific generated/manual methods are invoked (e.g., `MyEnum::variant_x()`, `former.field_y()`, standalone `variant_z()`)? + * What are the key inputs provided to these methods? + * What is the nature of the primary assertion (e.g., "Asserts the `got` instance (produced by the former) is equal to an `expected` instance (manually constructed to represent the correct state).", "Asserts that a subformer is returned and can be used to set inner fields.", "Asserts that a compile-time error occurs for an invalid attribute combination using `trybuild`."). + * **For `_derive.rs` files:** Mention that it relies on `#[derive(Former)]` for code generation and typically includes shared test logic via `include!("...")`. + * **For `_manual.rs` files:** Mention that it contains a hand-written former implementation and includes shared test logic via `include!("...")`. + * **For `compile_fail/*.rs` files:** The file contains code that intentionally uses an attribute or enum structure in a way that violates a documented behavior rule (i.e., `#[subform_scalar]` on a unit variant). The test is accepted if `trybuild` confirms this results in a compilation error, thereby validating the macro's error reporting for this specific invalid scenario." +* **Comment Style:** All added `//!` comments should be clear, concise, grammatically correct, and follow Rust documentation comment conventions. Use Markdown for lists or emphasis if it enhances readability. Aim for reasonable line lengths. +* **Pre-Analysis Output:** Before proposing comments for an increment, the AI must provide its pre-analysis findings for the targeted file(s) as specified in the "Increment Template". +* **Incremental Processing:** Modify files one increment at a time, following the "Increment Template." +* **Verification:** After each increment, request user to apply changes and run `cargo check --package former --tests`. **The code must compile successfully after adding comments. If adding comments introduces a compilation error (e.e., a syntax error in the comment itself), that specific error must be fixed. Pre-existing test failures or logic errors are out of scope.** +* **No Functional Changes:** This task is purely for documentation and review. No functional code changes should be made to the tests or macro logic unless a comment itself causes a trivial syntax issue that prevents compilation. +* **Handling `xxx`/`qqq` Comments:** During the review of each test file, if any existing `// xxx :` or `// qqq :` comments are encountered, their presence and a brief summary of their content should be noted in the "Notes & Insights" section of the `plan.md` for that increment. Addressing or resolving these comments is out of scope for this plan. +* **`mod.rs` Files Review:** If, during the review of test files, it's discovered that an enum test file exists in the directories but is not declared in its respective `mod.rs` file, this should be noted in the "Notes & Insights" for that increment. Activating it is out of scope. + +## Notes & Insights +* This plan focuses exclusively on documenting existing enum tests by adding comments. It does not involve fixing failing tests or implementing new features. +* The "Expected Enum Former Behavior Rules" section is critical for determining coverage. +* The "Increment Template" will be used for detailed planning of each increment. +* The `_only_test.rs` files, when shared, will have their documentation reflect their broader applicability. +* **[Date/Inc #] Note:** Increment 3 and 11 both reference `generics_in_tuple_variant_only_test.rs`.

1. **`//! Purpose: ...`**: - * Start with "Purpose:". - * Clearly and concisely describe the main goal of the test file. What specific aspect of the `Former` derive macro's behavior for enums is this file intended to verify? - * Mention the specific enum variant structure(s) (e.g., "unit variants", "single-field tuple variants with generics", "multi-field named struct variants") and any key attributes (e.g., `#[scalar]`, `#[subform_scalar]`, `#[standalone_constructors]`) being tested in this file. - * State whether the file is for `derive` macro testing, `manual` implementation testing, or `shared test logic` (`_only_test.rs`). - * For `compile_fail` tests, clearly state the specific incorrect usage or error condition it's designed to trigger and verify, referencing the relevant behavior rule that is being intentionally violated. - * **For `_only_test.rs` files:** The purpose should state that it provides shared test assertions/logic for both derived and manual implementations of [specific feature/variant type]. - 2. **`//! Coverage: ...`**: - * Start with "Coverage:". - * List the specific Rule IDs (e.e., "Rule 1a", "Rule 3d.i") from the "Expected Enum Former Behavior Rules" section that the tests in this file primarily demonstrate or validate. - * Briefly explain *what aspect* of the rule is being tested if the rule is broad and the test is specific (e.g., "Rule 4b - specifically the 'returns Former' case for standalone constructors with partial args"). - * If a test covers interactions between multiple rules (e.g., a variant attribute combined with an enum-level attribute), list all relevant rules and briefly note the interaction. - * **For `_only_test.rs` files:** This comment should summarize all rules covered by the test functions within it, which are then applied to both `_derive.rs` and `_manual.rs` files that include it. - 3. **`//! Test Relevance/Acceptance Criteria: ...`**: - * Start with "Test Relevance/Acceptance Criteria:". - * Describe the key actions performed by the test code and the primary assertions made that validate its stated purpose and coverage. This should explain *how* the test verifies the intended behavior. - * Be specific about the test's mechanics: - * What specific enum structures or attributes are defined/used in this test? - * What specific generated/manual methods are invoked (e.g., `MyEnum::variant_x()`, `former.field_y()`, standalone `variant_z()`)? - * What are the key inputs provided to these methods? - * What is the nature of the primary assertion (e.g., "Asserts the `got` instance (produced by the former) is equal to an `expected` instance (manually constructed to represent the correct state).", "Asserts that a subformer is returned and can be used to set inner fields.", "Asserts that a compile-time error occurs for an invalid attribute combination using `trybuild`."). - * **For `_derive.rs` files:** Mention that it relies on `#[derive(Former)]` for code generation and typically includes shared test logic via `include!("...")`. - * **For `_manual.rs` files:** Mention that it contains a hand-written former implementation and includes shared test logic via `include!("...")`. - * **For `compile_fail/*.rs` files:** The file contains code that intentionally uses an attribute or enum structure in a way that violates a documented behavior rule (i.e., `#[subform_scalar]` on a unit variant). The test is accepted if `trybuild` confirms this results in a compilation error, thereby validating the macro's error reporting for this specific invalid scenario." -* **Comment Style:** All added `//!` comments should be clear, concise, grammatically correct, and follow Rust documentation comment conventions. Use Markdown for lists or emphasis if it enhances readability. Aim for reasonable line lengths. -* **Pre-Analysis Output:** Before proposing comments for an increment, the AI must provide its pre-analysis findings for the targeted file(s) as specified in the "Increment Template". -* **Incremental Processing:** Modify files one increment at a time, following the "Increment Template." -* **Verification:** After each increment, request user to apply changes and run `cargo check --package former --tests`. **The code must compile successfully after adding comments. If adding comments introduces a compilation error (e.e., a syntax error in the comment itself), that specific error must be fixed. Pre-existing test failures or logic errors are out of scope.** -* **No Functional Changes:** This task is purely for documentation and review. No functional code changes should be made to the tests or macro logic unless a comment itself causes a trivial syntax issue that prevents compilation. -* **Handling `xxx`/`qqq` Comments:** During the review of each test file, if any existing `// xxx :` or `// qqq :` comments are encountered, their presence and a brief summary of their content should be noted in the "Notes & Insights" section of the `plan.md` for that increment. Addressing or resolving these comments is out of scope for this plan. -* **`mod.rs` Files Review:** If, during the review of test files, it's discovered that an enum test file exists in the directories but is not declared in its respective `mod.rs` file, this should be noted in the "Notes & Insights" for that increment. Activating it is out of scope. - -## Notes & Insights -* This plan focuses exclusively on documenting existing enum tests by adding comments. It does not involve fixing failing tests or implementing new features. -* The "Expected Enum Former Behavior Rules" section is critical for determining coverage. -* The "Increment Template" will be used for detailed planning of each increment. -* The `_only_test.rs` files, when shared, will have their documentation reflect their broader applicability. -* **[Date/Inc #] Note:** Increment 3 and 11 both reference `generics_in_tuple_variant_only_test.rs`.

Purpose: Tests the `#[derive(Former)]` macro's generation of constructors for single-field and multi-field tuple variants within a generic enum with bounds. This file focuses on verifying the derive-based implementation, particularly the default behavior when `#[scalar]` is commented out. //! //! Coverage: -//! - Rule 3d (Tuple + Single-Field + Default): Verifies subformer generation for a single-field tuple variant with generics when `#[scalar]` is absent (default behavior). -//! - Rule 3f (Tuple + Multi-Field + Default): Verifies subformer generation for a multi-field tuple variant with generics when `#[scalar]` is absent (default behavior). Note: This test/manual implementation currently tests subformer behavior for multi-field tuple variants, which contradicts the documented Rule 3f stating default for multi-field tuple is scalar. The documentation here reflects the current test behavior. -//! - Rule 1d (Tuple + Single-Field + `#[scalar]`): Relevant to the scenario where `#[scalar]` is applied to a single-field tuple variant with generics. (Note: `#[scalar]` is commented out in this file, so default behavior is expected and tested). -//! - Rule 1f (Tuple + Multi-Field + `#[scalar]`): Relevant to the scenario where `#[scalar]` is applied to a multi-field tuple variant with generics. (Note: `#[scalar]` is commented out in this file, so default behavior is expected and tested). -//! - Rule 4b (Option 2 Logic): Relevant to the subformer mechanism used for `Variant2` in the test logic/manual implementation. +//! - Rule 3d (Tuple + Single-Field + Default): Verifies `Enum::variant() -> InnerFormer<...>` for a generic enum. +//! - Rule 3f (Tuple + Multi-Field + Default): Verifies `Enum::variant(T1, T2, ...) -> Enum` for a generic enum. (Note: Tests in `_only_test.rs` included by this file seem to expect subformer behavior for multi-field variants, which contradicts this rule. The comment reflects the rule as defined in the plan). +//! - Rule 4b (Option 2 Logic): Related to the subformer mechanism used for `Variant1` (as tested) and expected for `Variant2` (as tested, contradicting Rule 3f). //! //! Test Relevance/Acceptance Criteria: -//! - Defines a generic enum `EnumScalarGeneric` with single-field (`Variant1`) and multi-field (`Variant2`) tuple variants, both containing generic types and bounds. -//! - Applies `#[derive(Former)]` to the enum. -//! - The `#[scalar]` attribute is commented out on both variants, ensuring default behavior is tested. +//! - Defines a generic enum `EnumScalarGeneric` with variants `Variant1(InnerScalar)` and `Variant2(InnerScalar, bool)`. //! - Includes shared test logic from `scalar_generic_tuple_only_test.rs`. -//! - The tests in the included file call the static methods `variant_1()` and `variant_2()` (generated by the derive macro). -//! - For `variant_1()`, the test expects a direct scalar return and uses `.into()`, verifying Rule 3d (default for single-field). -//! - For `variant_2()`, the test expects a former builder return, uses setters `._0()` and `._1()`, and calls `.form()`, verifying the current test/manual behavior for multi-field default (which is subformer, contradicting Rule 3f). -//! - Asserts that the resulting enum instances match manually constructed expected values. -//! - This file relies on `#[derive(Former)]` for code generation and includes shared test logic via `include!("scalar_generic_tuple_only_test.rs")`. +//! - Relies on `#[derive(Former)]` to generate static methods (`variant_1`, `variant_2`). +//! - The included tests invoke these methods and use `.into()` for `variant_1` (expecting scalar) and setters/`.form()` for `variant_2` (expecting subformer), asserting the final enum instance matches manual construction.

The content should adhere to the criteria outlined in the `### Requirements` section under "Comment Content". - -**For a file like `module/core/former/tests/inc/enum_unit_tests/generics_in_tuple_variant_unit_derive.rs`:** -```rust -//! Purpose: Tests the `#[derive(Former)]` macro's generation of constructors for unit variants -//! within an enum that has generic parameters and bounds. This file focuses on verifying -//! the derive-based implementation. -//! -//! Coverage: -//! - Rule 3a (Unit + Default): Verifies `Enum::variant() -> Enum` for a generic enum. -//! - Rule 1a (Unit + `#[scalar]`): Verifies `Enum::variant() -> Enum` (as default for unit is scalar) for a generic enum. -//! - (Implicitly) Rule 4a: If `#[standalone_constructors]` were active on `EnumOuter`, this test would also cover -//! the generation of `fn other_variant() -> EnumOuter`. -//! -//! Test Relevance/Acceptance Criteria: -//! - Defines a generic enum `EnumOuter` with a unit variant `OtherVariant`. -//! - Instantiates `EnumOuter` with a concrete type `MyType` that fulfills the `Copy` bound. -//! - Invokes the derived static method `EnumOuter::::other_variant()`. -//! - Asserts that the `got` instance is equal to an `expected` instance, which is manually -//! constructed as `EnumOuter::::OtherVariant`. This confirms the constructor produces the correct variant instance. -``` - ## Increments -**Increment Template: Document Test File/Group** -* **Target Crate(s):** `former` -* **Enum Aspect Focus:** [Unit | Unnamed/Tuple | Named/Struct | Complex/Mixed] -* **Target File(s):** [List of specific `.rs` files for this increment] -* **Pre-Analysis (AI to output this in Detailed Planning - Output 4):** - * Identified enum variant structures in target file(s): [e.g., "Unit variants", "Single-field tuple variant with `#[scalar]`"] - * Key attributes present: [e.e., `#[scalar]`, `#[standalone_constructors]` on enum] - * Relevant "Expected Enum Former Behavior Rule IDs": [e.g., "1a, 4a"] - * Brief summary of how test functions appear to exercise these rules: [e.g., "Test `basic_construction` calls `Enum::variant()` and compares with manual construction.

These tests seem to expect scalar behavior for single-field tuple variants and subformer behavior for multi-field tuple variants, which aligns with Rule 3d but contradicts Rule 3f (multi-field default should be scalar). The `#[scalar]` attributes are commented out in the derive file, which should result in default behavior.

Also, the `#[scalar]` attributes are commented out in the `_derive.rs` file, which should result in default behavior according to the rules, but the tests seem to expect scalar behavior for `Variant1` and subformer for `Variant2`.

Check for consistency in comments. - * **Verification Strategy:** Run `cargo check --package former --tests`. - * Commit Message: `docs(former): Final review of enum test documentation` + * Commit Message: [To be proposed upon successful completion of this increment] ### Requirements -* **Adherence:** Strictly follow `code/gen` instructions, Design Rules, and Codestyle Rules for all modifications. -* **Comment Content:** Each targeted test file **must** have the following three `//!` (file-level doc comments) added at the very beginning, before any `use` statements or code, in the specified order: - 1. **`//! Purpose: ...`**: - * Start with "Purpose:". - * Clearly and concisely describe the main goal of the test file. What specific aspect of the `Former` derive macro's behavior for enums is this file intended to verify? - * Mention the specific enum variant structure(s) (e.g., "unit variants", "single-field tuple variants with generics", "multi-field named struct variants") and any key attributes (e.g., `#[scalar]`, `#[subform_scalar]`, `#[standalone_constructors]`) being tested in this file. - * State whether the file is for `derive` macro testing, `manual` implementation testing, or `shared test logic` (`_only_test.rs`). - * For `compile_fail` tests, clearly state the specific incorrect usage or error condition it's designed to trigger and verify, referencing the relevant behavior rule that is being intentionally violated. - * **For `_only_test.rs` files:** The purpose should state that it provides shared test assertions/logic for both derived and manual implementations of [specific feature/variant type]. - 2. **`//! Coverage: ...`**: - * Start with "Coverage:". - * List the specific Rule IDs (e.e., "Rule 1a", "Rule 3d.i") from the "Expected Enum Former Behavior Rules" section that the tests in this file primarily demonstrate or validate. - * Briefly explain *what aspect* of the rule is being tested if the rule is broad and the test is specific (e.g., "Rule 4b - specifically the 'returns Former' case for standalone constructors with partial args"). - * If a test covers interactions between multiple rules (e.g., a variant attribute combined with an enum-level attribute), list all relevant rules and briefly note the interaction. - * **For `_only_test.rs` files:** This comment should summarize all rules covered by the test functions within it, which are then applied to both `_derive.rs` and `_manual.rs` files that include it. - 3. **`//! Test Relevance/Acceptance Criteria: ...`**: - * Start with "Test Relevance/Acceptance Criteria:". - * Describe the key actions performed by the test code and the primary assertions made that validate its stated purpose and coverage. This should explain *how* the test verifies the intended behavior. - * Be specific about the test's mechanics: - * What specific enum structures or attributes are defined/used in this test? - * What specific generated/manual methods are invoked (e.g., `MyEnum::variant_x()`, `former.field_y()`, standalone `variant_z()`)? - * What are the key inputs provided to these methods? - * What is the nature of the primary assertion (e.g., "Asserts the `got` instance (produced by the former) is equal to an `expected` instance (manually constructed to represent the correct state).", "Asserts that a subformer is returned and can be used to set inner fields.", "Asserts that a compile-time error occurs for an invalid attribute combination using `trybuild`."). - * **For `_derive.rs` files:** Mention that it relies on `#[derive(Former)]` for code generation and typically includes shared test logic via `include!("...")`. - * **For `_manual.rs` files:** Mention that it contains a hand-written former implementation and includes shared test logic via `include!("...")`. - * **For `compile_fail/*.rs` files:** The file contains code that intentionally uses an attribute or enum structure in a way that violates a documented behavior rule (i.e., `#[subform_scalar]` on a unit variant). The test is accepted if `trybuild` confirms this results in a compilation error, thereby validating the macro's error reporting for this specific invalid scenario." -* **Comment Style:** All added `//!` comments should be clear, concise, grammatically correct, and follow Rust documentation comment conventions. Use Markdown for lists or emphasis if it enhances readability. Aim for reasonable line lengths. -* **Pre-Analysis Output:** Before proposing comments for an increment, the AI must provide its pre-analysis findings for the targeted file(s) as specified in the "Increment Template". -* **Incremental Processing:** Modify files one increment at a time, following the "Increment Template." -* **Verification:** After each increment, request user to apply changes and run `cargo check --package former --tests`. **The code must compile successfully after adding comments. If adding comments introduces a compilation error (e.e., a syntax error in the comment itself), that specific error must be fixed. Pre-existing test failures or logic errors are out of scope.** -* **No Functional Changes:** This task is purely for documentation and review. No functional code changes should be made to the tests or macro logic unless a comment itself causes a trivial syntax issue that prevents compilation. -* **Handling `xxx`/`qqq` Comments:** During the review of each test file, if any existing `// xxx :` or `// qqq :` comments are encountered, their presence and a brief summary of their content should be noted in the "Notes & Insights" section of the `plan.md` for that increment. Addressing or resolving these comments is out of scope for this plan. -* **`mod.rs` Files Review:** If, during the review of test files, it's discovered that an enum test file exists in the directories but is not declared in its respective `mod.rs` file, this should be noted in the "Notes & Insights" for that increment. Activating it is out of scope. +* **Adherence:** Strictly follow `code/gen` instructions, Design Rules (especially "Proc Macro: Development Workflow"), and Codestyle Rules for all modifications. +* **Incremental Verification:** After each increment involving code changes: + * Ensure the relevant code compiles (`cargo check --package former --tests`). + * Run all active tests within the `enum_unit_tests` module (`cargo test --package former --test tests -- --test-threads=1 --nocapture enum_unit_tests`). Analyze logs critically. +* **Failure Analysis:** If tests fail, explicitly consider if the failure is due to an **incorrect test expectation** or a **bug in the macro implementation**. Utilize the `#[debug]` attribute on the enum in the `_derive.rs` file to output the generated code. Analyze this output and compare it with the `_manual.rs` implementation to pinpoint the source of the error before proposing fixes. +* **Proc Macro Workflow:** Each test-focused increment (1-5) will meticulously follow the Proc Macro Development Workflow: + 1. Plan and ensure `_manual.rs` implementation exists and is correct. + 2. Plan and ensure `_only_test.rs` shared test logic exists and is correct. + 3. Verify manual implementation (`_manual.rs` + `_only_test.rs`) passes. + 4. Plan and ensure `_derive.rs` macro invocation site exists. + 5. If `_derive.rs` tests fail while manual passes, analyze (using `#[debug]` output if helpful) and propose fixes to `former_meta` or the test itself if the expectation is wrong. + 6. Verify `_derive.rs` implementation passes. +* **No Plan Commits:** This plan file (`-plan.md`) will not be committed to version control. +* **Scoped Testing:** Test execution will be limited to the `former` package and specifically the relevant test modules (e.g., `enum_unit_tests`), avoiding full workspace tests. +* **No Clippy:** Clippy checks will not be part of the verification steps. ## Notes & Insights -* This plan focuses exclusively on documenting existing enum tests by adding comments. It does not involve fixing failing tests or implementing new features. -* The "Expected Enum Former Behavior Rules" section is critical for determining coverage. -* The "Increment Template" will be used for detailed planning of each increment. -* The `_only_test.rs` files, when shared, will have their documentation reflect their broader applicability. -* **[Date/Inc #] Note:** Increment 3 and 11 both reference `generics_in_tuple_variant_only_test.rs`. The documentation for this shared file should be comprehensive enough to cover its usage in both unit and tuple variant contexts, likely handled in Increment 11. -* **[Date/Inc #] Note:** The commit messages in the Increment Template now include `[enum_aspect_focus]` for better categorization. -* **[2025-05-10/Inc 1] Note:** Started detailed planning for Increment 1: Document `unit_variant_*` files.

The derive macro generates the static constructor for `SimpleUnit` correctly if the `Complex` variant is removed and `#[former(standalone_constructors)]` is removed. However, if `#[former(standalone_constructors)]` is present, the standalone constructor for `SimpleUnit` is not generated, even if `Complex` is removed or simplified to `data: i32`. This indicates an issue with `#[former(standalone_constructors)]` for this specific enum structure (`MixedEnum`) that was not present for the simpler `Status` enum in Increment 1. - * **Conclusion for Increment 5:** The derive macro functionality for standalone constructors for unit variants is problematic when the enum is named `MixedEnum` or has other structural differences from the basic `Status` enum, even if other variants are simplified or removed.

(NOW FIXED) -* **Identified Issue (Increment 4):** `former::Former` derive macro fails to compile for generic enums due to complex trait bound requirements for generic parameters. (NOW FIXED) -* **Identified Issue (Increment 5):** `former::Former` derive macro fails to generate standalone constructors for unit variants in an enum that also contains variants with named fields (struct-like variants), when `#[former(standalone_constructors)]` is used on the enum.

The `enum_unit_tests/mod.rs` file should now only contain active and relevant test modules for unit variants. - * **Detailed Plan Steps:** - 1. Review `module/core/former/tests/inc/enum_unit_tests/mod.rs` one last time to ensure all `mod` declarations are for active, relevant unit variant tests. Remove any remaining commented-out lines that were processed or deemed permanently irrelevant. (Done) - 2.

This was fixed by parsing `ItemAttributes` once in `derive_former.rs` and passing the attributes and the derived `has_debug` boolean down. -* **Standalone Constructor Naming (Increment 8):** Handlers like `tuple_zero_fields_handler.rs` were generating standalone constructors with names that could clash if multiple enums were in the same file. Fixed by prefixing with enum name (e.g., `zero_tuple_variant`). +* **Standalone Constructor Naming (Increment 8 & 27):** Handlers like `tuple_zero_fields_handler.rs` were generating standalone constructors with names that could clash if multiple enums were in the same file. Fixed by prefixing with enum name (e.g., `zero_tuple_variant`). Later discovered that for simple unit/zero-field tuple variants, the derive macro generates standalone functions named after the variant (snake_case), not prefixed by enum name. Test files were updated accordingly. * **PhantomData Issue (Increment 10.A):** `former::Former` derive attempts to create formers for `PhantomData` variants/fields, causing compilation errors. Fixed by modifying `tuple_single_field_subform.rs` to generate a direct/scalar-like constructor for variants whose single field is `PhantomData`. -* **Access Violation (Increment 21):** A `STATUS_ACCESS_VIOLATION` (0xc0000005) started occurring when compiling `former` tests.

Ensure `module/core/former/tests/inc/enum_unit_tests/mod.rs` has comments explaining which factors each group of tests covers. -* **New Goal (from further user feedback):** - 1. Correctly relocate `tuple_zero_fields` tests to `enum_unnamed_tests`. - 2. Ensure all test groups in `enum_unit_tests` strictly pertain to unit variants. - 3. Add detailed comments to `module/core/former/tests/inc/mod.rs` explaining the testing aspects covered by each of its declared enum test modules. - 4. Address compiler warnings in `former` and `former_meta` crates. - 5. Make macro debug printing conditional (disable by default for production). - 6.

Intensively analyzing and integrating reusable components from the `macro_tools` crate into the enum unit variant handling logic (`former_meta/src/derive_former/former_enum/unit_variant_handler.rs`). + 2. Analyzing the existing enum unit variant handling logic in `former_meta` to identify and potentially extract generalizable, well-tested utilities into the `macro_tools` crate. +* The process will include proposing an initial detailed refactoring solution, critiquing it, and then implementing an improved version. +* All changes must strictly adhere to `code/gen` instructions, Design Rules, and Codestyle Rules. + +### Relevant Context +* **Primary Crates for Modification:** + * `module/core/former_meta` (specifically `src/derive_former/former_enum/unit_variant_handler.rs` and potentially `src/derive_former/former_enum.rs`) + * `module/core/macro_tools` (for potential additions and modifications) +* **Key `macro_tools` Files for Analysis (Full Analysis in Increment 1):** + * All files within `module/core/macro_tools/src/` including `attr.rs`, `attr_prop.rs`, `diag.rs`, `ident.rs`, `kw.rs`, `generic_params.rs`, `typ.rs`, `item.rs`, `name.rs`, `punctuated.rs`, `quantifier.rs`, `tokens.rs`, etc. +* **Key `former_meta` Files for Analysis:** + * `module/core/former_meta/src/derive_former/former_enum/unit_variant_handler.rs` + * `module/core/former_meta/src/derive_former/former_enum.rs` (for context, dispatch, and `EnumVariantHandlerContext`) + * `module/core/former_meta/src/derive_former/field_attrs.rs` + * `module/core/former_meta/src/derive_former/struct_attrs.rs` (for `ItemAttributes` like `standalone_constructors`, `debug`) * **Key Documentation for Reference:** * `module/core/former/Readme.md` * `module/core/former/advanced.md` - * This plan's "Expected Enum Former Behavior" section. + * Existing `plan.md` files for "Expected Enum Former Behavior" rules. * **Workspace:** Yes, this is part of a Cargo workspace. -* **Target File Structure:** Primarily working within existing test files or creating new ones following the `_manual.rs`, `_derive.rs`, `_only_test.rs` pattern within relevant test directories. - -### Expected Enum Former Behavior -(Content remains the same as before) - -1. **`#[scalar]` Attribute:** - * **Unit Variant (Rule 1a):** Generates `Enum::variant() -> Enum`. - * **Zero-Field Variant (Tuple) (Rule 1b):** Generates `Enum::variant() -> Enum`. - * **Zero-Field Variant (Struct) (Rule 1c):** Generates `Enum::variant() -> Enum`. - * ...

The correct location is `enum_unnamed_tests` as these tests cover zero-field tuple variants (e.g., `Variant()`). The internal compilation errors in `tuple_zero_fields_only_test.rs` need to be resolved to fully verify this. A compiler crash (Access Violation) occurred when testing `enum_unit_tests` after these moves. - * **Detailed Plan Steps:** - * **21.A: Temporarily Comment Out `tuple_zero_fields` Tests to Isolate Access Violation** - 1. Modify `module/core/former/tests/inc/enum_unnamed_tests/mod.rs`: Comment out `mod tuple_zero_fields_derive;` and `mod tuple_zero_fields_manual;`. (Done) - 2.

Modify `module/core/former/tests/inc/enum_unnamed_tests/mod.rs` to add and **uncomment**: - ```rust - // Coverage for `tuple_zero_fields_*` tests: - // - Tests zero-field tuple variants e.g., `MyEnum::Variant()`. - // - Verifies Rules 1b (scalar), 3b (default), and 4a (standalone_constructors). - mod tuple_zero_fields_derive; - mod tuple_zero_fields_manual; - ``` - (Done, but modules kept commented due to internal errors and access violation debugging). - * **Crucial Design Rules:** Structuring: Organize by Feature or Layer, Problem Isolation. - * **Verification Strategy:** - * `cargo test --package former --test tests -- inc::enum_unit_tests` compiled and ran without access violation after 21.A. - * (Deferred) `cargo test --package former --test tests -- inc::enum_unnamed_tests` - all tests in this module must pass. - * Commit Message: `refactor(former): Relocate tuple_zero_fields tests and temporarily disable for stability` - -* [✅] **Increment 22: Add Detailed Aspect Comments to `inc/mod.rs`** - * **Pre-Analysis:** The main test module file `module/core/former/tests/inc/mod.rs` needs comments explaining the scope of each `enum_*_tests` submodule. - * **Detailed Plan Steps:** - 1. Read `module/core/former/tests/inc/mod.rs`. (Done) - 2. Added `///` and `//` comments to `module/core/former/tests/inc/mod.rs` to document the purpose of each `enum_*_tests` submodule. (Done) - 3. File formatting maintained.

This should be disabled by default for production/normal use but remain available for debugging. - * **Detailed Plan Steps:** - 1. Modified `former_meta/Cargo.toml` to add the optional feature: `former_diagnostics_print_generated = []`. (Done) - 2. In `module/core/former_meta/src/derive_former.rs`, gated the `diag::report_print` call within the main `former` function with `#[cfg(feature = "former_diagnostics_print_generated")]`. (Done) - 3. In `module/core/former_meta/src/derive_former.rs`, gated the `diag::report_print` call within the `mutator` function similarly. (Done) - 4.

(Done) - * Commit Message: `feat(former_meta): Make debug printing of generated code conditional` - -* [✅] **Increment 27: Fix and Re-enable `tuple_zero_fields` Tests** - * **Pre-Analysis:** The `tuple_zero_fields` tests are currently commented out and had compilation errors. The core issue seems to be name resolution within the `tuple_zero_fields_only_test.rs` when included by `_manual.rs` and `_derive.rs`. - * **Detailed Plan Steps:** - 1. Corrected `tuple_zero_fields_manual.rs` to define `EnumWithZeroFieldTuple` and standalone functions `variant_zero_default`, `variant_zero_scalar` to match derive output. (Done) - 2. Ensured `tuple_zero_fields_derive.rs` defines `EnumWithZeroFieldTuple` and has `#[former(standalone_constructors)]`. (Done) - 3. Corrected `tuple_zero_fields_only_test.rs` to expect standalone functions `variant_zero_default` and `variant_zero_scalar`. (Done) - 4. Modified `module/core/former/tests/inc/enum_unnamed_tests/mod.rs`: Uncommented `mod tuple_zero_fields_derive;` and `mod tuple_zero_fields_manual;`. (Done) - * **Crucial Design Rules:** Proc Macro: Development Workflow. - * **Verification Strategy:** - * `cargo test --package former --test tests -- inc::enum_unnamed_tests` passed. (Done) - * `cargo test --package former --test tests` passed without access violations (228 tests). (Done) - * Commit Message: `fix(former): Resolve compilation errors and re-enable tuple_zero_fields tests` - -### Requirements -(Content remains the same as before) - -## Notes & Insights -(Content remains the same as before, new issues identified in increments will be added here) -* **Core Fix (Increment 8):** The `has_debug` flag (and `ItemAttributes` generally) was not being correctly determined and propagated from the main derive macro entry point (`derive_former.rs`) to `former_for_enum` and `former_for_struct`. This was fixed by parsing `ItemAttributes` once in `derive_former.rs` and passing the attributes and the derived `has_debug` boolean down. -* **Standalone Constructor Naming (Increment 8 & 27):** Handlers like `tuple_zero_fields_handler.rs` were generating standalone constructors with names that could clash if multiple enums were in the same file. Fixed by prefixing with enum name (e.g., `zero_tuple_variant`). Later discovered that for simple unit/zero-field tuple variants, the derive macro generates standalone functions named after the variant (snake_case), not prefixed by enum name. Test files were updated accordingly. -* **PhantomData Issue (Increment 10.A):** `former::Former` derive attempts to create formers for `PhantomData` variants/fields, causing compilation errors. Fixed by modifying `tuple_single_field_subform.rs` to generate a direct/scalar-like constructor for variants whose single field is `PhantomData`. -* **Access Violation (Increment 21):** A `STATUS_ACCESS_VIOLATION` (0xc0000005) started occurring when compiling `former` tests. Temporarily commenting out the `tuple_zero_fields` tests resolved this for `inc::enum_unit_tests`, and subsequent incremental testing showed all other `inc` submodules also pass individually and together. Re-enabling `tuple_zero_fields` after fixing name inconsistencies did not reintroduce the crash. +* **Other Active Plans:** The refactoring plan for `former_meta` (`former_meta/plan.md`) should be considered, as changes here might affect its assumptions. + +### Project Requirements +* (This section should be cumulative. Assuming previous project requirements like Rust edition 2021, documentation for public APIs, etc., are still in effect. New project-level requirements identified will be added here.) +* **Behavioral Equivalence:** Refactoring must not change the externally observable behavior or the generated code structure of the `Former` macro for enum unit variants, unless explicitly justified by a bug fix or alignment with documented "Expected Enum Former Behavior". Existing tests in the `former` crate for unit variants serve as the primary regression guard. +* **`macro_tools` Generalization:** All new or modified code in `macro_tools` must be general-purpose, well-documented, and include unit tests. Utilities should not be overly specific to `former_meta`'s internal implementation details. +* **Code Quality:** Code changes should demonstrably improve clarity, maintainability, and reduce redundancy in `unit_variant_handler.rs`. +* **Error Reporting:** If `macro_tools` utilities are used for error handling, the quality (clarity, span accuracy) of compiler error messages generated by `former_meta` must be maintained or improved. +* **Performance:** The refactoring should not introduce measurable performance regressions in macro expansion time. (Primarily a consideration for complex macros, but good to keep in mind). +* **Rule Adherence:** All new and modified code must strictly adhere to the system prompt's Design Rules and Codestyle Rules, overriding existing styles in the repository if they conflict. +* **Proc Macro Workflow:** While this is primarily a refactoring task, if any part of the core macro logic generation for unit variants is significantly altered (beyond just using helper functions), the principles of the "Proc Macro: Development Workflow" (e.g., clear separation of concerns, testability) should be respected. +* **Verification Scope:** All `cargo` commands for verification (check, test, clippy) **must be scoped to individual packages** (e.g., `cargo test --package former_meta`) unless an increment explicitly plans for workspace-level integration testing as a final step. + +### Expected Behavior Rules (Enum Unit Variants) +* **Rule 1a (Unit + `#[scalar]`):** Generates `Enum::variant() -> Enum`. (Handled by: `unit_variant_handler.rs`) +* **Rule 2a (Unit + `#[subform_scalar]`):** Error. (Checked in: `unit_variant_handler.rs`) +* **Rule 3a (Unit + Default):** Generates `Enum::variant() -> Enum`. (Handled by: `unit_variant_handler.rs`) +* **Rule 4a (`#[standalone_constructors]` on Enum):** + * For unit variants, generates top-level `fn variant_name() -> EnumName` (or `fn enum_name_variant_name() -> EnumName` depending on naming convention for standalone, to be confirmed from existing behavior). The name should be snake_case. + +### Increments + +* [⚫] **Increment 1: Analyze `macro_tools` for `former_meta` (Enum Unit Variants)** + * Target Crate(s): `macro_tools` (read-only), `former_meta` (analysis target) + * Detailed Plan Step 1: Systematically review each module and public item in `macro_tools/src/`. + * Detailed Plan Step 2: For each `macro_tools` utility, assess its direct applicability to simplifying or improving the logic in `former_meta/src/derive_former/former_enum/unit_variant_handler.rs` and its interaction with `former_meta/src/derive_former/former_enum.rs` (e.g., `EnumVariantHandlerContext`, attribute parsing). Consider: + * Attribute parsing (`attr.rs`, `attr_prop.rs`): For `#[scalar]`, `#[subform_scalar]` on variants, and `#[standalone_constructors]`, `#[debug]` on the enum. + * Identifier generation/manipulation (`ident.rs`, `name.rs`, `kw.rs`): For constructor names, handling raw identifiers. + * Generic parameter handling (`generic_params.rs`, `generic_args.rs`): For generic enums and their constructors. + * Error reporting (`diag.rs`): For `syn_err!`, `return_syn_err!`. + * Code quoting (`qt!`, `quote!`). + * Type analysis (`typ.rs`): If any type introspection is needed for unit variants (less likely for units). + * Detailed Plan Step 3: **Output:** Produce a detailed report mapping specific `macro_tools` utilities to concrete code sections or logic patterns in `unit_variant_handler.rs` and `former_enum.rs` (related to unit variants).

It also needs to interact with the enum-level `#[standalone_constructors]` attribute (parsed in `struct_attrs.rs` and available in `EnumVariantHandlerContext`). +* The primary logic in `unit_variant_handler.rs` involves generating a simple static method and, if `#[standalone_constructors]` is present, a corresponding standalone function. Both typically construct the enum variant directly (e.g., `EnumName::VariantName`). +* `macro_tools::ident::ident_maybe_raw` will be useful for generating constructor names from variant idents, especially if variants use raw identifiers (e.g., `r#fn`). +* `macro_tools::diag::syn_err!` and `return_syn_err!` are already suitable for error reporting (e.g., for `#[subform_scalar]` on a unit variant). +* `macro_tools::generic_params::decompose` and related functions will be crucial if the enum is generic, to correctly propagate generics to standalone constructors. +* The `EnumVariantHandlerContext` provides necessary context like `vis`, `generics`, `enum_name`, `variant_ident`, and `struct_attrs`. The refactoring should leverage this context effectively.

Assuming previous project requirements like Rust edition 2021, documentation for public APIs, etc., are still in effect. New project-level requirements identified will be added here.) -* **Behavioral Equivalence:** Refactoring must not change the externally observable behavior or the generated code structure of the `Former` macro for enum unit variants, unless explicitly justified by a bug fix or alignment with documented "Expected Enum Former Behavior". Existing tests in the `former` crate for unit variants serve as the primary regression guard. -* **`macro_tools` Generalization:** All new or modified code in `macro_tools` must be general-purpose, well-documented, and include unit tests. Utilities should not be overly specific to `former_meta`'s internal implementation details. -* **Code Quality:** Code changes should demonstrably improve clarity, maintainability, and reduce redundancy in `unit_variant_handler.rs`. -* **Error Reporting:** If `macro_tools` utilities are used for error handling, the quality (clarity, span accuracy) of compiler error messages generated by `former_meta` must be maintained or improved. -* **Performance:** The refactoring should not introduce measurable performance regressions in macro expansion time. (Primarily a consideration for complex macros, but good to keep in mind). -* **Rule Adherence:** All new and modified code must strictly adhere to the system prompt's Design Rules and Codestyle Rules, overriding existing styles in the repository if they conflict. -* **Proc Macro Workflow:** While this is primarily a refactoring task, if any part of the core macro logic generation for unit variants is significantly altered (beyond just using helper functions), the principles of the "Proc Macro: Development Workflow" (e.g., clear separation of concerns, testability) should be respected. -* **Verification Scope:** All `cargo` commands for verification (check, test, clippy) **must be scoped to individual packages** (e.g., `cargo test --package former_meta`) unless an increment explicitly plans for workspace-level integration testing as a final step. - -### Expected Behavior Rules (Enum Unit Variants) -* **Rule 1a (Unit + `#[scalar]`):** Generates `Enum::variant() -> Enum`. (Handled by: `unit_variant_handler.rs`) -* **Rule 2a (Unit + `#[subform_scalar]`):** Error. (Checked in: `unit_variant_handler.rs`) -* **Rule 3a (Unit + Default):** Generates `Enum::variant() -> Enum`. (Handled by: `unit_variant_handler.rs`) -* **Rule 4a (`#[standalone_constructors]` on Enum):** - * For unit variants, generates top-level `fn variant_name() -> EnumName` (or `fn enum_name_variant_name() -> EnumName` depending on naming convention for standalone, to be confirmed from existing behavior). The name should be snake_case. - -### Increments - -* [✅] **Increment 1: Analyze `macro_tools` for `former_meta` (Enum Unit Variants)** - * Target Crate(s): `macro_tools` (read-only), `former_meta` (analysis target) - * Pre-Analysis: The goal is to identify how `macro_tools` can simplify `former_meta`'s unit variant handling. This requires a thorough understanding of `macro_tools` capabilities and the current implementation in `former_meta/src/derive_former/former_enum/unit_variant_handler.rs`. The existing "Notes & Insights" section already provides some initial pointers (e.g., `ident_maybe_raw`, `syn_err!`, `generic_params::decompose`). - * Detailed Plan Step 1: Systematically review each module and public item in `module/core/macro_tools/src/`. This involves using `list_files` to get an accurate list of modules and then conceptually (or with `read_file` if needed for specific complex utilities) understanding their purpose. - * Detailed Plan Step 2: For each identified `macro_tools` utility, assess its direct applicability to simplifying or improving the logic in `module/core/former_meta/src/derive_former/former_enum/unit_variant_handler.rs` and its interaction with `module/core/former_meta/src/derive_former/former_enum.rs` (e.g., `EnumVariantHandlerContext`, attribute parsing). Consider: - * Attribute parsing (`attr.rs`, `attr_prop.rs`): For `#[scalar]`, `#[subform_scalar]` on variants, and `#[standalone_constructors]`, `#[debug]` on the enum. - * Identifier generation/manipulation (`ident.rs`, `name.rs`, `kw.rs`): For constructor names, handling raw identifiers. - * Generic parameter handling (`generic_params.rs`, `generic_args.rs`): For generic enums and their constructors. - * Error reporting (`diag.rs`): For `syn_err!`, `return_syn_err!`. - * Code quoting (`qt!`, `quote!`). - * Type analysis (`typ.rs`): If any type introspection is needed for unit variants (less likely for units). - * Detailed Plan Step 3: **Output (as a textual report in the AI's response, not a file):** Produce a detailed report mapping specific `macro_tools` utilities to concrete code sections or logic patterns in `unit_variant_handler.rs` and `former_enum.rs` (related to unit variants). For each mapping, explain the potential benefit (e.g., "Replace custom ident logic with `ident::ident_maybe_raw`", "Use `AttributePropertyOptionalSingletone` for `#[scalar]` flag"). This report will be the main deliverable of this increment. - * Crucial Design Rules: [Prioritize Reuse and Minimal Change], [Comments and Documentation]. - * Relevant Behavior Rules: Rules 1a, 2a, 3a, 4a (to ensure proposed `macro_tools` usage aligns with expected outcomes). - * Verification Strategy: User reviews the detailed analysis report and mapping presented in the AI's response. No code changes, so no compilation or tests. - * Test Matrix: Not applicable for this analysis increment. - * Commit Message: `docs(former_meta): Analyze macro_tools for refactoring unit variant handling` - -* [✅] **Increment 2: Analyze `former_meta` (Enum Unit Variants) for `macro_tools` Generalizations** - * Target Crate(s): `former_meta` (read-only), `macro_tools` (analysis target) - * Pre-Analysis: The goal is to identify custom logic in `former_meta`'s unit variant handling that could be generalized and moved to `macro_tools`. This requires careful review of `former_meta/src/derive_former/former_enum/unit_variant_handler.rs` and related context. - * Detailed Plan Step 1: Review `former_meta/src/derive_former/former_enum/unit_variant_handler.rs` and related logic in `former_meta/src/derive_former/former_enum.rs` (e.g., parts of `EnumVariantHandlerContext` or its setup if relevant to unit variants specifically and generalizable). This will involve using `read_file` to examine these files. - * Detailed Plan Step 2: Identify any custom logic, patterns, or helper functions used for unit variant handling that are sufficiently generic and could be beneficial to other procedural macro development if moved to `macro_tools`. - * Detailed Plan Step 3: **Output (as a textual report in the AI's response, not a file):** Document findings as a list of concrete proposals for new utilities or modifications for `macro_tools`. Each proposal must include: - * Proposed function/struct/trait signature. - * Target module within `macro_tools`. - * Clear description of its purpose and generic applicability. - * A brief example of how it would be used. - * Crucial Design Rules: [Traits: Encourage Modular Design], [Visibility: Keep Implementation Details Private]. - * Relevant Behavior Rules: N/A for this analysis increment, but proposals should align with general good API design. - * Verification Strategy: User reviews the documented analysis and concrete proposals for `macro_tools` presented in the AI's response. No code changes, so no compilation or tests. - * Test Matrix: Not applicable for this analysis increment. - * Commit Message: `docs(macro_tools): Analyze former_meta unit variant logic for potential generalizations` - -* [✅] **Increment 3: Propose Initial Detailed Refactoring Solution for Enum Unit Variants** - * Target Crate(s): `former_meta`, `macro_tools` - * Pre-Analysis: Based on the analyses from Increments 1 and 2, the goal is to draft a detailed initial refactoring plan for `former_meta/src/derive_former/former_enum/unit_variant_handler.rs`. This involves showing how `macro_tools` utilities (existing or proposed in Increment 2) will be used. - * Detailed Plan Step 1: Draft the detailed initial refactoring plan for `former_meta/src/derive_former/former_enum/unit_variant_handler.rs`. This will involve: - * Identifying specific code sections in the current `unit_variant_handler.rs` (read in Increment 2). - * Mapping these sections to the `macro_tools` utilities identified in Increment 1 (e.g., `attr::Attributes::retrieve_optional_singletone_bool`, `diag::return_syn_err!`, `ident::new_ident_from_cased_str` (proposed), `generic_params::GenericsRef` methods (proposed), `tokens::qt!`). - * Showing conceptual "before-and-after" code snippets or detailed pseudo-code. - * Detailed Plan Step 2: **Output (as a textual report in the AI's response, not a file):** For `unit_variant_handler.rs`, provide: - * Conceptual "before-and-after" code snippets (or pseudo-code) demonstrating how `macro_tools` utilities will replace or augment existing logic. - * Clear explanation of changes to data flow or helper function usage. - * Detailed Plan Step 3: **Output (as a textual report in the AI's response, not a file):** For `macro_tools`, provide: - * Finalized signatures and intended module placement for any new utilities proposed in Increment 2 (i.e., `ident::new_ident_from_cased_str` and `generic_params::GenericsRef` helper methods). - * Detailed Plan Step 4: Outline the expected impact on code size, readability, and maintainability in `unit_variant_handler.rs`. - * Detailed Plan Step 5: Briefly assess if this refactoring impacts the `former_meta/plan.md` for splitting large files. (Given `unit_variant_handler.rs` is already relatively small and focused, significant impact is unlikely, but it should be considered). - * Crucial Design Rules: [Prioritize Reuse and Minimal Change], [Code Style: Do Not Reformat Arbitrarily] (when showing existing code), [Comments and Documentation] (for new proposed utilities). - * Relevant Behavior Rules: Rules 1a, 2a, 3a, 4a (to ensure the proposed refactoring maintains correct behavior). - * Verification Strategy: User reviews the detailed refactoring solution presented in the AI's response. No code changes, so no compilation or tests. - * Test Matrix: Not applicable for this planning/proposal increment. - * Commit Message: `docs(former_meta): Propose initial detailed refactoring for unit variant handling` - -* [✅] **Increment 4: Critique and Improve Refactoring Solution** - * Target Crate(s): `former_meta`, `macro_tools` - * Input: The detailed refactoring solution from Increment 3. - * Pre-Analysis: The goal is to critically evaluate the refactoring solution proposed in Increment 3 and suggest improvements. This involves checking for effectiveness, simplification, generalization quality, complexity, rule adherence, and maintainability. - * Detailed Plan Step 1: Perform a self-critique of the *detailed* initial refactoring solution from Increment 3. - * **Effectiveness & Simplification:** - * Does the proposed use of `macro_tools::diag::return_syn_err!` simplify error handling for `#[subform_scalar]`? Yes, it's more direct. - * Does the proposed `macro_tools::ident::new_ident_from_cased_str` significantly simplify identifier creation? Yes, it encapsulates complex keyword and raw string logic. - * Do the proposed `GenericsRef` methods simplify generic token generation? Yes, they reduce boilerplate. - * Is the switch to `macro_tools::tokens::qt!` a significant improvement? It's mostly stylistic but aligns with using `macro_tools`. - * **Generalization Quality:** - * Is `new_ident_from_cased_str` truly generic? Yes, identifier generation with case conversion and keyword/raw handling is a common macro task. The proposed signature seems reasonable. - * Are the `GenericsRef` helper methods (`impl_generics_tokens_if_any`, `ty_generics_tokens_if_any`, `type_path_tokens_if_any`) generic? Yes, quoting generics conditionally is common. - * **Complexity Trade-offs:** - * Does introducing these new `macro_tools` utilities add undue complexity? No, they seem to encapsulate existing complexity into reusable forms. The benefit outweighs the cost of adding these small, focused utilities. - * **Rule Adherence & Correctness:** - * Does the proposed refactoring align with "Expected Enum Former Behavior"? Yes, the core logic of what's generated remains the same. - * Are there edge cases missed for `new_ident_from_cased_str`? The proposal mentions returning `Result` for robustness, which is good. The keyword list/detection mechanism needs to be solid. - * Are generics handled correctly? The proposed `GenericsRef` methods aim to standardize this. - * **Maintainability Impact:** - * Will `unit_variant_handler.rs` be easier to maintain? Yes, due to simplification and delegation. - * Will the new `macro_tools` utilities be maintainable? Yes, if well-tested and documented. - * Detailed Plan Step 2: **Output (as a textual report in the AI's response, not a file):** Based on the critique, propose specific, actionable improvements or alternatives to the refactoring plan. - * Crucial Design Rules: [Prioritize Reuse and Minimal Change], [Comments and Documentation]. - * Relevant Behavior Rules: Rules 1a, 2a, 3a, 4a. - * Verification Strategy: User reviews the critique and the improved refactoring solution. No code changes. - * Test Matrix: Not applicable. - * Commit Message: `docs(former_meta): Critique and improve refactoring plan for unit variants` - -* [✅] **Increment 5: Implement Improved Refactoring (Enum Unit Variants in `former_meta`)** - * Target Crate(s): `former_meta` - * Pre-Analysis: Review the approved improved refactoring solution from Increment 4. This means the changes will be based on using the (yet to be implemented in `macro_tools`) utilities: - * `macro_tools::diag::return_syn_err!` (existing, but usage confirmed) - * `macro_tools::ident::new_ident_from_cased_str` (proposed in Inc 4, to be implemented in Inc 6) - * `macro_tools::generic_params::GenericsRef` enhanced methods (`impl_generics_tokens_if_any`, `ty_generics_tokens_if_any`, `type_path_tokens_if_any`, `where_clause_tokens_if_any`) (proposed in Inc 4, to be implemented in Inc 6). - * **Crucially, since the `macro_tools` utilities are not yet implemented, this increment will involve writing the `former_meta` code *as if* they exist.** The actual compilation of `former_meta` will only fully succeed after Increment 6 is completed. This is acceptable as per the plan structure. - * Detailed Plan Step 1: Modify `former_meta/src/derive_former/former_enum/unit_variant_handler.rs` according to the approved plan from Increment 4. This involves: - * Replacing the `#[subform_scalar]` error handling with `macro_tools::diag::return_syn_err!`. - * Replacing the manual identifier creation for `method_ident` with a call to the conceptual `macro_tools::ident::new_ident_from_cased_str`. - * Replacing manual generic quoting with calls to the conceptual `macro_tools::generic_params::GenericsRef` helper methods. - * Potentially switching `quote!` to `macro_tools::tokens::qt!`. - * Detailed Plan Step 2: Ensure all existing tests in `former` crate for enum unit variants *would conceptually* continue to pass with identical behavior. Actual test runs for `former_meta` will depend on Increment 6. - * Crucial Design Rules: [Prioritize Reuse and Minimal Change], [Proc Macro: Development Workflow]. - * Relevant Behavior Rules: Rules 1a, 2a, 3a, 4a. - * Verification Strategy: - * User applies changes to `former_meta/src/derive_former/former_enum/unit_variant_handler.rs`. - * `cargo check --package former_meta` will likely fail due to missing `macro_tools` utilities, which is expected at this stage. The primary verification is code review against the plan from Increment 4. - * A full `cargo test --package former --test tests -- inc::enum_unit_tests` will be deferred until after Increment 6. The immediate goal is to ensure the `unit_variant_handler.rs` code *structurally* matches the refactoring plan. - * Test Matrix: Not applicable for this refactoring increment directly, but existing tests cover behavior. - * Commit Message: `refactor(former_meta): Improve unit variant handling using macro_tools` - -* [⏳] **Increment 6: Implement Generalizations (New Utilities in `macro_tools`)** - * Target Crate(s): `macro_tools` - * Pre-Analysis: Review the approved new utilities for `macro_tools` from Increment 4. These are: - 1. `macro_tools::ident::new_ident_from_cased_str` - 2. `macro_tools::generic_params::GenericsRef` enhanced methods: - * `impl_generics_tokens_if_any()` - * `ty_generics_tokens_if_any()` - * `where_clause_tokens_if_any()` - * `type_path_tokens_if_any()` - * (And the conceptual private helper `split_for_impl_syn_components` or equivalent logic to access decomposed generic parts). - * Detailed Plan Step 1: Implement these utilities in `module/core/macro_tools/src/ident.rs` and `module/core/macro_tools/src/generic_params.rs`. - * Detailed Plan Step 2: Add comprehensive unit tests for these new utilities. This will involve creating new test files or extending existing ones in `module/core/macro_tools/tests/inc/` (e.g., a new `ident_general_tests.rs`, `generic_params_ref_tests.rs` or similar, and updating `module/core/macro_tools/tests/inc/mod.rs`). - * Detailed Plan Step 3: Update `module/core/macro_tools/src/lib.rs` and relevant module files (`ident.rs`, `generic_params.rs` themselves if they define `pub` items, or their parent `mod.rs` if they are submodules) to correctly export the new public utilities. - * Detailed Plan Step 4: Add clear `///doc` comments for all new public items in `macro_tools`. - * Crucial Design Rules: [Traits: Encourage Modular Design], [Visibility: Keep Implementation Details Private], [Comments and Documentation], [Testing: Plan with a Test Matrix When Writing Tests]. - * Relevant Behavior Rules: N/A directly, but API design should be robust and adhere to Rust conventions. - * Verification Strategy: - * User applies changes to `macro_tools`. - * `cargo check --package macro_tools` must pass. - * `cargo test --package macro_tools` must pass. - * `cargo doc --package macro_tools --no-deps` should build successfully. - * `cargo clippy --package macro_tools --all-targets -- -D warnings` should pass. - * Test Matrix: - * **For `new_ident_from_cased_str` (in `macro_tools::ident`):** - * ID: T6.1, Input: (`"normal_ident"`, `span`, `false`), Expected: `Ok(syn::Ident::new("normal_ident", span))` - * ID: T6.2, Input: (`"fn"`, `span`, `false`), Expected: `Ok(syn::Ident::new_raw("fn", span))` (keyword becomes raw) - * ID: T6.3, Input: (`"fn"`, `span`, `true`), Expected: `Ok(syn::Ident::new_raw("fn", span))` (original raw, cased is keyword) - * ID: T6.4, Input: (`"my_raw_ident"`, `span`, `true`), Expected: `Ok(syn::Ident::new_raw("my_raw_ident", span))` (original raw, cased not keyword) - * ID: T6.5, Input: (`""`, `span`, `false`), Expected: `Err(_)` (empty string) - * ID: T6.6, Input: (`"with space"`, `span`, `false`), Expected: `Err(_)` (invalid ident chars) - * ID: T6.7, Input: (`"ValidIdent"`, `span`, `false`), Expected: `Ok(syn::Ident::new("ValidIdent", span))` (function assumes input is already cased as desired for the ident name itself, only keyword/raw status is handled). - * **For `GenericsRef` methods (in `macro_tools::generic_params`):** - * (Setup: `let generics_std: syn::Generics = syn::parse_quote! { where T: Debug > };`) - * (Setup: `let generics_empty: syn::Generics = syn::parse_quote! { };`) - * (Setup: `let enum_name: syn::Ident = syn::parse_quote! { MyEnum };`) - * ID: T6.8 (`impl_generics_tokens_if_any` with `generics_std`): Expected: `Ok(quote!( ))` - * ID: T6.9 (`impl_generics_tokens_if_any` with `generics_empty`): Expected: `Ok(quote!( ))` - * ID: T6.10 (`ty_generics_tokens_if_any` with `generics_std`): Expected: `Ok(quote!( ))` - * ID: T6.11 (`ty_generics_tokens_if_any` with `generics_empty`): Expected: `Ok(quote!( ))` - * ID: T6.12 (`where_clause_tokens_if_any` with `generics_std`): Expected: `Ok(quote!( where T: Debug ))` - * ID: T6.13 (`where_clause_tokens_if_any` with `generics_empty`): Expected: `Ok(quote!( ))` - * ID: T6.14 (`type_path_tokens_if_any` with `generics_std`, `enum_name`): Expected: `Ok(quote!( MyEnum:: ))` - * ID: T6.15 (`type_path_tokens_if_any` with `generics_empty`, `enum_name`): Expected: `Ok(quote!( MyEnum ))` - * Commit Message: `feat(macro_tools): Add new utilities generalized from former_meta enum handling` - -* [⚫] **Increment 7: Final Verification and Documentation Update** - * Target Crate(s): `former_meta`, `macro_tools`, `former` - * Detailed Plan Step 1: Run `cargo clippy --package former_meta --all-targets -- -D warnings` and address any new lints. - * Detailed Plan Step 2: Run `cargo clippy --package macro_tools --all-targets -- -D warnings` and address any new lints. - * Detailed Plan Step 3: Run `cargo test --package former_meta` and `cargo test --package macro_tools`. - * Detailed Plan Step 4: Run `cargo test --package former --test tests -- inc::enum_unit_tests` (and any other directly affected test suites) to ensure no regressions. - * Detailed Plan Step 5: Update any relevant internal documentation or comments in `former_meta` (especially `unit_variant_handler.rs`) and `macro_tools` to reflect the refactoring and new utilities. - * Detailed Plan Step 6: Review if the `former_meta/plan.md` (for splitting large files) needs adjustment based on changes to `unit_variant_handler.rs` or `former_enum.rs`. Propose updates if necessary. - * Verification Strategy: User confirms all checks pass and reviews documentation updates and any proposed changes to other plans. - * Commit Message: `chore(former): Final verification and docs update after unit variant refactor` - -### Requirements (Task-Specific) -* The refactoring should prioritize clarity, maintainability, and testability of `unit_variant_handler.rs`. -* Any utilities moved to or created in `macro_tools` must be genuinely reusable, well-documented with examples (if applicable for complex utilities), and not overly specific to `former_meta`'s internal logic. -* The "Expected Enum Former Behavior" for unit variants must be strictly preserved or corrected if bugs are found and approved as part of the plan. -* Naming conventions for standalone constructors (e.g., `variant_name()` vs `enum_name_variant_name()`) should be consistent with the established patterns in `former_meta` or clarified if ambiguous. -* Consider the impact on generic enums: ensure refactoring correctly handles generics in unit variant constructors (both static and standalone). - -### Notes & Insights -* (This section will be populated as the plan progresses) -* `unit_variant_handler.rs` currently handles `#[scalar]` (which is the default behavior for unit variants) and correctly errors on `#[subform_scalar]`. It also needs to interact with the enum-level `#[standalone_constructors]` attribute (parsed in `struct_attrs.rs` and available in `EnumVariantHandlerContext`). -* The primary logic in `unit_variant_handler.rs` involves generating a simple static method and, if `#[standalone_constructors]` is present, a corresponding standalone function. Both typically construct the enum variant directly (e.g., `EnumName::VariantName`). -* `macro_tools::ident::ident_maybe_raw` will be useful for generating constructor names from variant idents, especially if variants use raw identifiers (e.g., `r#fn`). -* `macro_tools::diag::syn_err!` and `return_syn_err!` are already suitable for error reporting (e.g., for `#[subform_scalar]` on a unit variant). -* `macro_tools::generic_params::decompose` and related functions will be crucial if the enum is generic, to correctly propagate generics to standalone constructors. -* The `EnumVariantHandlerContext` provides necessary context like `vis`, `generics`, `enum_name`, `variant_ident`, and `struct_attrs`. The refactoring should leverage this context effectively. +* **Target File Structure:** No major structural changes, primarily adding comments to existing files. + +### Expected Enum Former Behavior + +This plan adheres to the following rules for `#[derive(Former)]` on enums: + +1. **`#[scalar]` Attribute:** + * **Unit Variant (Rule 1a):** Generates `Enum::variant() -> Enum`.

Requirements +* **Adherence:** Strictly follow `code/gen` instructions, Design Rules, and Codestyle Rules for all modifications. +* **Comment Content:** Each targeted test file **must** have the following three `//!` (file-level doc comments) added at the very beginning, before any `use` statements or code, in the specified order: + 1. **`//! Purpose: ...`**: + * Start with "Purpose:". + * Clearly and concisely describe the main goal of the test file. What specific aspect of the `Former` derive macro's behavior for enums is this file intended to verify? + * Mention the specific enum variant structure(s) (e.g., "unit variants", "single-field tuple variants with generics", "multi-field named struct variants") and any key attributes (e.g., `#[scalar]`, `#[subform_scalar]`, `#[standalone_constructors]`) being tested in this file. + * State whether the file is for `derive` macro testing, `manual` implementation testing, or `shared test logic` (`_only_test.rs`). + * For `compile_fail` tests, clearly state the specific incorrect usage or error condition it's designed to trigger and verify, referencing the relevant behavior rule that is being intentionally violated. + * **For `_only_test.rs` files:** The purpose should state that it provides shared test assertions/logic for both derived and manual implementations of [specific feature/variant type]. + 2. **`//! Coverage: ...`**: + * Start with "Coverage:". + * List the specific Rule IDs (e.e., "Rule 1a", "Rule 3d.i") from the "Expected Enum Former Behavior Rules" section that the tests in this file primarily demonstrate or validate. + * Briefly explain *what aspect* of the rule is being tested if the rule is broad and the test is specific (e.g., "Rule 4b - specifically the 'returns Former' case for standalone constructors with partial args"). + * If a test covers interactions between multiple rules (e.g., a variant attribute combined with an enum-level attribute), list all relevant rules and briefly note the interaction. + * **For `_only_test.rs` files:** This comment should summarize all rules covered by the test functions within it, which are then applied to both `_derive.rs` and `_manual.rs` files that include it. + 3. **`//! Test Relevance/Acceptance Criteria: ...`**: + * Start with "Test Relevance/Acceptance Criteria:". + * Describe the key actions performed by the test code and the primary assertions made that validate its stated purpose and coverage. This should explain *how* the test verifies the intended behavior. + * Be specific about the test's mechanics: + * What specific enum structures or attributes are defined/used in this test? + * What specific generated/manual methods are invoked (e.g., `MyEnum::variant_x()`, `former.field_y()`, standalone `variant_z()`)? + * What are the key inputs provided to these methods? + * What is the nature of the primary assertion (e.g., "Asserts the `got` instance (produced by the former) is equal to an `expected` instance (manually constructed to represent the correct state).", "Asserts that a subformer is returned and can be used to set inner fields.", "Asserts that a compile-time error occurs for an invalid attribute combination using `trybuild`."). + * **For `_derive.rs` files:** Mention that it relies on `#[derive(Former)]` for code generation and typically includes shared test logic via `include!("...")`. + * **For `_manual.rs` files:** Mention that it contains a hand-written former implementation and includes shared test logic via `include!("...")`. + * **For `compile_fail/*.rs` files:** The file contains code that intentionally uses an attribute or enum structure in a way that violates a documented behavior rule (i.e., `#[subform_scalar]` on a unit variant). The test is accepted if `trybuild` confirms this results in a compilation error, thereby validating the macro's error reporting for this specific invalid scenario." +* **Comment Style:** All added `//!` comments should be clear, concise, grammatically correct, and follow Rust documentation comment conventions. Use Markdown for lists or emphasis if it enhances readability. Aim for reasonable line lengths. +* **Pre-Analysis Output:** Before proposing comments for an increment, the AI must provide its pre-analysis findings for the targeted file(s) as specified in the "Increment Template". +* **Incremental Processing:** Modify files one increment at a time, following the "Increment Template." +* **Verification:** After each increment, request user to apply changes and run `cargo check --package former --tests`. **The code must compile successfully after adding comments. If adding comments introduces a compilation error (e.e., a syntax error in the comment itself), that specific error must be fixed. Pre-existing test failures or logic errors are out of scope.** +* **No Functional Changes:** This task is purely for documentation and review. No functional code changes should be made to the tests or macro logic unless a comment itself causes a trivial syntax issue that prevents compilation. +* **Handling `xxx`/`qqq` Comments:** During the review of each test file, if any existing `// xxx :` or `// qqq :` comments are encountered, their presence and a brief summary of their content should be noted in the "Notes & Insights" section of the `plan.md` for that increment. Addressing or resolving these comments is out of scope for this plan. +* **`mod.rs` Files Review:** If, during the review of test files, it's discovered that an enum test file exists in the directories but is not declared in its respective `mod.rs` file, this should be noted in the "Notes & Insights" for that increment. Activating it is out of scope. + +## Notes & Insights +* This plan focuses exclusively on documenting existing enum tests by adding comments.

Introduction & Core Concepts + +#### 0.1. Goals of `unilang` + +`unilang` provides a unified way to define command-line utility interfaces once, automatically enabling consistent interaction across multiple modalities such as CLI, GUI, TUI, AUI, and Web APIs. + +The core goals of `unilang` are: + +1. **Consistency:** A single way to define commands and their arguments, regardless of how they are presented or invoked. +2. **Discoverability:** Easy ways for users and systems to find available commands and understand their usage. +3. **Flexibility:** Support for various methods of command definition (compile-time, run-time, declarative, procedural). +4. **Extensibility:** Provide structures that enable a `utility1` integrator to build an extensible system with compile-time `Extension Module`s and run-time command registration. +5. **Efficiency:** Support for efficient parsing and command dispatch, with potential for compile-time optimizations. +6. **Interoperability:** Standardized representation for commands, enabling integration with other tools or web services, including auto-generation of WEB endpoints. +7. **Robustness:** Clear error handling and validation mechanisms. +8. **Security:** Provide a framework for defining and enforcing secure command execution, which `utility1` can leverage. + +#### 0.2. Key Terminology (Glossary) + +* **`unilang`**: This specification; the language defining how commands, arguments, and interactions are structured. +* **`utility1`**: A generic placeholder for the primary utility or application that implements and interprets `unilang`. The actual name will vary depending on the specific tool. The developer of `utility1` is referred to as the "integrator." +* **Command**: A specific action or operation that can be invoked (e.g., `.files.copy`). +* **Command Definition**: The complete specification of a command, including its name, arguments, routine, and other attributes, as defined by `unilang`. +* **Namespace**: A dot-separated hierarchical structure to organize commands (e.g., `.files.`, `.network.`). The root namespace is denoted by `.`. +* **Argument**: A parameter that a command accepts to modify its behavior or provide data. +* **Argument Definition**: The specification of an argument, including its name, type (`kind`), optionality, etc., as defined by `unilang`. +* **Argument Value**: The actual data provided for an argument during command invocation. After parsing, this represents the unescaped content. +* **Routine (Handler Function)**: The executable code associated with a command that performs its logic. Its signature is defined by `unilang` expectations. +* **Modality**: A specific way of interacting with `utility1` using `unilang` (e.g., CLI, GUI, WEB Endpoint). +* **Command Expression (CLI)**: The textual representation of a command invocation in the CLI, as defined by `unilang`. +* **Generic Instruction**: An intermediate representation of a command parsed from input, before semantic analysis and binding to a `CommandDefinition`. +* **`VerifiedCommand`**: An internal representation of a command ready for execution, with all arguments parsed, validated, and typed according to `unilang` rules. +* **Type (`kind`)**: The data type of an argument (e.g., `String`, `Integer`, `Path`), as defined or extended within the `unilang` framework. +* **`Extension Module`**: A compile-time module or crate that provides `unilang`-compatible components like modalities, core commands, or custom types to `utility1`. +* **Global Argument**: An argument processed by `utility1` itself to configure its behavior for the current invocation, distinct from command-specific arguments but using the same `unilang` `key::value` syntax. +* **`ExecutionContext`**: An object, whose content is largely defined by `utility1`, passed to command routines, providing access to global settings, configuration, and `utility1`-level services. +* **`OutputData`**: A `unilang`-defined structured object representing the successful result of a command. +* **`ErrorData`**: A `unilang`-defined structured object representing an error that occurred during processing or execution. +* **Interpreter (Execution Engine)**: The component within `utility1` that executes a `VerifiedCommand`. + +#### 0.3. Versioning Strategy (for `unilang` spec) + +This `unilang` specification document will follow Semantic Versioning (SemVer 2.0.0). +* **MAJOR** version when incompatible API changes are made to the core `unilang` structure. +* **MINOR** version when functionality is added in a backward-compatible manner. +* **PATCH** version when backward-compatible bug fixes are made to the specification. + +Individual commands defined using `unilang` can also have their own versions (see Section 2.1.2). + +--- + +### 1. Language Syntax, Structure, and Processing (CLI) + +`unilang` commands are primarily invoked via a `utility1` in a CLI context. The general structure of an invocation is: + +`utility1 [global_argument...] [command_expression] [;; command_expression ...]` + +This input string might be processed by `utility1` directly, or `utility1` might receive arguments already somewhat tokenized by the invoking shell (e.g., as a list of strings). The `unilang` processing phases described below must be robust to both scenarios, applying `unilang`-specific parsing rules. + +The processing of this CLI input occurs in distinct phases: + +#### 1.1. CLI Input Processing Phases + +The interpretation of a `unilang` CLI string by `utility1` **must** proceed through the following conceptual phases: + +1. **Phase 1: Lexical and Syntactic Analysis (String to Generic Instructions)** + * **Input Handling:** The parser must be capable of consuming input either as a single, continuous string or as a sequence of pre-tokenized string segments (e.g., arguments from `std::env::args()`). An internal input abstraction is recommended. + * **Lexical Analysis (Lexing):** Whether as a distinct step or integrated into parsing, this stage identifies fundamental `unilang` symbols. + * If input is a single string, this involves tokenizing the raw string. + * If input is a sequence of strings, lexical analysis applies *within* each string to handle `unilang`-specific quoting, escapes, and to identify `unilang` operators (like `::`, `;;`, `?`) that might be part of or adjacent to these string segments. + * **Syntactic Analysis (Parsing):** The (potentially abstracted) token stream is parsed against the `unilang` grammar (see Appendix A.2) to build a sequence of "Generic Instructions." + * A **Generic Instruction** at this stage represents a potential command invocation or a help request. It contains: + * The raw, unresolved command name string (e.g., `".files.copy"`). + * A list of raw argument values, distinguishing between potential positional (default) arguments and named arguments (still as `key_string::value_string` pairs). These values should be stored as string slices (`&str`) referencing the original input if possible, to minimize allocations. The content of these values after parsing represents the unescaped string. + * Flags indicating a help request (`?`). + * Information about command separators (` ;; `) to delineate multiple Generic Instructions. + * This phase **does not** require any knowledge of defined commands, their arguments, or types. It only validates the syntactic structure of the input according to `unilang` rules. + * Global arguments (Section 1.2) are also identified and separated at this stage. + * The parser should aim to track location information (e.g., byte offset in a single string, or segment index and offset within a segment for pre-tokenized input) to aid in error reporting. + * Input that is empty or contains only whitespace (after initial global whitespace skipping) should result in an empty list of Generic Instructions, not an error. + +2. **Phase 2: Semantic Analysis and Command Binding (Generic Instructions to `VerifiedCommand`)** + * Each Generic Instruction is processed against `utility1`'s **Unified Command Registry** (Section 2.4). + * **Command Resolution:** The raw command name from the Generic Instruction is resolved to a specific `CommandDefinition`. If not found, an error (`UNILANG_COMMAND_NOT_FOUND`) is generated. + * **Argument Binding & Typing:** + * Raw argument values from the Generic Instruction are mapped to the `ArgumentDefinition`s of the resolved command. + * Positional values are assigned to the `is_default_arg`. + * Named arguments are matched by name/alias. + * Values are parsed and validated against their specified `kind` and `validation_rules`. + * `optional` and `default_value` attributes are applied. + * This phase transforms a Generic Instruction into a **`VerifiedCommand`** object (Section 0.2), which is a fully typed and validated representation of the command to be executed. If any semantic errors occur (missing mandatory arguments, type mismatches, validation failures), appropriate `ErrorData` is generated. + * Help requests (`?`) are typically handled at this stage by generating help output based on the resolved command or namespace definition, often bypassing `VerifiedCommand` creation for execution. + +3. **Phase 3: Verification and Optimization (Optional)** + * Before execution, `utility1` **may** perform additional verification or optimization steps on the `VerifiedCommand` or a sequence of them. + * This could include: + * Cross-command validation for sequences. + * Pre-fetching resources. + * Instruction reordering or "inlining" for common, performance-sensitive command patterns (an advanced optimization). + * This phase is not strictly mandated by `unilang` but is a point where an integrator can add advanced logic. + +4. **Phase 4: Execution** + * The `VerifiedCommand` (or a sequence of them) is passed to the **Interpreter / Execution Engine** (Section 5) to be acted upon. + +#### 1.2. Global Arguments + +* Global arguments are processed by `utility1` to control its behavior for the current invocation before any specific `command_expression` is processed (typically during or just after Phase 1 of CLI Input Processing). +* They use the same `key::value` syntax as command arguments (e.g., `output_format::json`, `log_level::debug`). +* The set of available global arguments is defined by `utility1` itself. +* These are not part of a specific command's definition but are recognized by the `utility1` parser at the top level. +* **Discovery of Global Arguments**: `utility1` implementations **must** provide `utility1 .system.globals ?` which outputs a structured description (see Section 3.2.6) of available global arguments, their purpose, types, default values, and status (e.g., Stable, Deprecated). `utility1` should issue warnings when deprecated global arguments are used. +* **Examples of potential Global Arguments:** + * `output_format::format` (e.g., `output_format::json`, `output_format::yaml`, `output_format::table`) - Controls default output format for commands in the invocation. + * `log_level::level` (e.g., `log_level::debug`) - Sets the logging verbosity for the current invocation. + * `locale::` (e.g., `locale::fr-FR`) - Suggests a localization for `utility1`'s output for the current invocation. + * `config_file::path/to/file.toml` - Specifies an alternative configuration file for this invocation. + * `on_error::policy` (e.g., `on_error::stop` (default), `on_error::continue`) - Governs behavior for command sequences. + +#### 1.3. Command Expression + +A `command_expression` (the input to Phase 1 processing after global arguments are handled) can be one of the following: + +* **Full Command Invocation:** `[namespace_path.]command_name [argument_value...] [named_argument...]` +* **Help/Introspection Request:** `[namespace_path.][command_name] ?` or `[namespace_path.]?` + +#### 1.4. Components of a Command Expression + +* **`namespace_path`**: A dot-separated path indicating a module or category of commands (e.g., `.files.`, `.network.`). + * A single dot `.` refers to the root namespace. +* **`command_name`**: The specific action to be performed (e.g., `copy`, `delete`, `list`). This is the final segment of the command's `FullName`. +* **`argument_value`**: A value provided to the command. After parsing, this represents the unescaped content of the value. + * **Default Argument Value**: If a command defines a default argument, its value can be provided without its name. It's typically the first unnamed value after the `command_name`. + * **Named Argument**: `argument_name::value` or `argument_name::"value with spaces"`. + * `argument_name`: The identifier for the argument. + * `::`: The key-value separator. + * `value`: The value assigned to the argument. + * **Single String Input:** Values with spaces or special `unilang` characters (like `;;`, `::`, `?` if not intended as operators) **must** be quoted using single or double quotes (e.g., `"some path/with space"`, `'value with :: literal'`). Unquoted spaces in a single string input will typically cause the value to be treated as multiple distinct tokens by the initial lexing stage. Standard shell quoting rules might apply first, then `unilang`'s parser re-evaluates quotes for its own syntax. + * **Slice of Strings Input:** If `utility1` receives pre-tokenized arguments, each string segment is a potential value. If such a segment itself contains `unilang` quotes (e.g., a segment is literally `"foo bar"` including the quotes), the `unilang` parser must still process these quotes to extract the actual content (`foo bar`). Escaped quotes (`\"`, `\'`) within `unilang`-quoted strings are treated as literal characters. +* **`;;`**: The command separator, allowing multiple command expressions to be processed sequentially. +* **`?`**: The introspection/help operator. + +#### 1.5. Examples + +1. **Copy files:** + `utility1 .files.copy src::dir1 dst::../dir2` +2. **Copy and then delete, with JSON output for all commands in this invocation:** + `utility1 output_format::json .files.copy src::dir1 dst::../dir2 ;; .files.delete src::dir1` +3. **Get help for the copy command:** + `utility1 .files.copy ?` +4. **List all commands in the root namespace:** + `utility1 .` +5. **Switch to TUI modality and then list files:** + `utility1 .modality.set target::tui ;; .files.list` +6. **Command with a default argument value and debug logging:** + `utility1 log_level::debug .log.message "This is a log entry"` + +--- + +### 2. Command Definition (`unilang` Core) + +#### 2.1. Command Anatomy + +A command is the fundamental unit of action in `unilang`. Each command definition comprises several attributes: + +* **Full Name (String, Mandatory)**: The unique, dot-separated, case-sensitive path identifying the command (e.g., `.files.copy`, `.admin.users.create`, `.file.create.temp`). + * **Naming Conventions**: + * **Command Paths**: Command paths are formed by segments separated by dots (`.`). Each segment **must** consist of lowercase alphanumeric characters (a-z, 0-9) and underscores (`_`) may be used to separate words within a segment if preferred over shorter, distinct segments (e.g., `.file.create_temp` or `.file.create.temp`). Using only lowercase alphanumeric characters for segments is also common (e.g. `.file.createtemp`). Dots are exclusively for separating these path segments. Names must not start or end with a dot, nor contain consecutive dots. The namespace `.system.` is reserved for core `unilang`/`utility1` functionality. + * **Argument Names**: Argument names (e.g., `input-string`, `user_name`, `force`) **should** consist of lowercase alphanumeric characters and **may** use `kebab-case` (e.g., `input-string`) or `snake_case` (e.g., `user_name`) for multi-word names to enhance readability. They must be unique within a command. +* **Hint/Description (String, Optional)**: A human-readable explanation of the command's purpose. Used in help messages and UI tooltips. `utility1` may implement localization for these strings. +* **Routine (Mandatory)**: A reference or link to the actual executable code (handler function) that implements the command's logic. This routine receives a `VerifiedCommand` object and an `ExecutionContext` object. +* **Arguments (List, Optional)**: A list defining the arguments the command accepts. See Section 2.2. +* **HTTP Method Hint (String, Optional)**: For WEB Endpoint modality, a suggested HTTP method (e.g., `GET`, `POST`, `PUT`, `DELETE`). If not provided, it can be inferred. +* **Tags/Categories (List, Optional)**: Keywords for grouping, filtering, or categorizing commands. +* **Examples (List, Optional)**: Illustrative usage examples of the command, primarily for CLI help. +* **Permissions (List, Optional)**: A list of permission identifiers required to execute this command. +* **Status (Enum, Optional, Default: `Stable`)**: Indicates the maturity or lifecycle state of the command. Values: `Experimental`, `Stable`, `Deprecated`. +* **Deprecation Message (String, Optional)**: If `status` is `Deprecated`, this message should explain the reason and suggest alternatives. +* **Command Version (String, Optional)**: Individual commands can have their own SemVer version (e.g., "1.0.2"). +* **Idempotent (Boolean, Optional, Default: `false`)**: If `true`, indicates the command can be safely executed multiple times with the same arguments without unintended side effects. + +##### 2.1.1. Namespaces + +Namespaces provide a hierarchical organization for commands, preventing naming conflicts and improving discoverability. +* A namespace is a sequence of identifiers separated by dots (e.g., `.files.utils.`). +* Commands are typically defined within a namespace. +* The root namespace `.` can also contain commands. +* Listing commands in a namespace (e.g., `utility1 .files.`) should show sub-namespaces and commands directly within that namespace. + +##### 2.1.2. Command Versioning & Lifecycle + +* **Command Version (String, Optional)**: Individual commands can have their own SemVer version. + * **Invocation of Specific Versions**: `unilang` itself doesn't prescribe a syntax like `.command@version`. Version management is typically handled by evolving the command or introducing new versions in different namespaces (e.g., `.v1.command`, `.v2.command`). If a `utility1` implementation supports direct versioned invocation, its parser must handle it before `unilang` command resolution. +* **Lifecycle:** + 1. **Experimental:** New commands that are subject to change. Should be used with caution. + 2. **Stable:** Commands considered reliable and with a stable interface. + 3. **Deprecated:** Commands planned for removal in a future version. `utility1` should issue a warning when a deprecated command is used. The `deprecation_message` should guide users. + 4. **Removed:** Commands no longer available. + +#### 2.2. Argument Specification + +Arguments define the inputs a command accepts. + +##### 2.2.1. Argument Attributes + +Each argument within a command's `arguments` list is defined by these attributes: + +* **`name` (String, Mandatory)**: The unique (within the command), case-sensitive identifier for the argument (e.g., `src`, `dst`, `force`, `user-name`). Follows naming conventions in Section 2.1. +* **`hint` (String, Optional)**: A human-readable description of the argument's purpose. `utility1` may localize this. +* **`kind` (String, Mandatory)**: Specifies the data type of the argument's value. See Section 2.2.2 for defined types. The final value passed to the command routine will be the unescaped content, parsed according to this kind. +* **`optional` (Boolean, Optional, Default: `false`)**: + * `false` (Mandatory): The argument must be provided. + * `true` (Optional): The argument may be omitted. +* **`default_value` (Any, Optional)**: A value to use if an optional argument is not provided. The type of `default_value` must be compatible with `kind`. This value is applied *before* type validation. +* **`is_default_arg` (Boolean, Optional, Default: `false`)**: + * If `true` for *one* argument in a command, its value can be provided in the CLI without specifying its name (positionally). The argument still requires a `name` for other modalities and explicit CLI invocation. + * If `is_default_arg` is true for an argument that accepts multiple values (due to `kind: List` or `multiple: true`), all subsequent positional tokens in the CLI (until a named argument `key::value`, `;;`, or `?` is encountered) are collected into this single default argument. +* **`interactive` (Boolean, Optional, Default: `false` for CLI, adaptable for other UIs)**: + * If `true`, and the argument is mandatory but not provided, and the current UI modality supports it, the system may prompt the user to enter the value. +* **`multiple` (Boolean, Optional, Default: `false`)**: + * If `true`, the argument can be specified multiple times in the CLI (e.g., `arg_name::val1 arg_name::val2`). The collected values are provided to the command routine as a list of the specified `kind`. See Section 2.2.2 for interaction with `List`. +* **`aliases` (List, Optional)**: A list of alternative short names for the argument (e.g., `s` as an alias for `source`). Aliases must be unique within the command's arguments and distinct from other argument names and follow naming conventions. +* **`tags` (List, Optional)**: For grouping arguments within complex commands, potentially for UI layout hints (e.g., "Basic", "Advanced", "Output"). +* **`validation_rules` (List or List, Optional)**: Custom validation logic or constraints beyond basic type checking. + * Examples: Regex pattern for strings (`"regex:^[a-zA-Z0-9_]+$"`), min/max for numbers (`"min:0"`, `"max:100"`), file must exist (`"file_exists:true"`), string length (`"min_length:5"`). The exact format of rules needs definition by `utility1` but should be clearly documented. +* **`sensitive` (Boolean, Optional, Default: `false`)**: + * If `true`, the argument's value should be treated as sensitive (e.g., passwords, API keys). UIs should mask it, and logs should avoid printing it or redact it. + +##### 2.2.2. Data Types (`kind`) + +The `kind` attribute specifies the expected data type of an argument. `unilang` defines a set of built-in types. The system should attempt to parse/coerce input strings (which are assumed to be unescaped at this stage) into these types. + +* **`String`**: A sequence of characters. +* **`Integer`**: A whole number. Validation rules can specify range. +* **`Float`**: A floating-point number. +* **`Boolean`**: A true or false value. Parsed from "true", "false", "yes", "no", "1", "0" (case-insensitive for strings). +* **`Path`**: A URI representing a file system path. Defaults to `file://` scheme if not specified. Handled as per Section 4.1. +* **`File`**: A `Path` that must point to a file. Validation can check for existence. +* **`Directory`**: A `Path` that must point to a directory. Validation can check for existence. +* **`Enum(Choice1|Choice2|...)`**: A string that must be one of the predefined, case-sensitive choices. (e.g., `Enum(Read|Write|Execute)`). +* **`URL`**: A Uniform Resource Locator (e.g., `http://`, `ftp://`, `mailto:`). +* **`DateTime`**: A date and time. Should support ISO 8601 format by default (e.g., `YYYY-MM-DDTHH:MM:SSZ`). +* **`Pattern`**: A regular expression pattern string. +* **`List`**: A list of elements of a specified `Type` (e.g., `List`, `List`). + * **CLI Syntax**: If `kind` is `List` (and the argument's `multiple` attribute is `false`): `arg_name::value1,value2,value3`. The list delimiter (default ',') can be specified in the type definition if needed (e.g., `List`). This syntax is for providing multiple values *within a single instance* of the argument. +* **Interaction with `multiple: true` attribute**: + * If `kind` is a non-list type (e.g., `String`) and the argument's `multiple` attribute is `true`: + * The argument value passed to the routine will be a `List`. + * **CLI Syntax**: Requires repeating the argument: `arg_name::val1 arg_name::val2 arg_name::val3`. Each `value` is parsed as `String`. + * If `kind` is `List` and the argument's `multiple` attribute is also `true`: This implies a "list of lists." + * **CLI Syntax**: `arg_name::val1,val2 arg_name::val3,val4`. Each `valX,valY` part is parsed as a list, and these lists are collected into an outer list. This should be used sparingly due to CLI complexity; accepting a single JSON string for such complex inputs is often clearer. +* **`Map`**: A key-value map (e.g., `Map`). + * **CLI Syntax**: `arg_name::key1=val1,key2=val2,key3=val3`. Keys and values follow standard quoting rules if they contain delimiters or spaces. The entry delimiter (default ',') and key-value separator (default '=') can be specified if needed, e.g., `Map`. +* **`JsonString` / `Object`**: For arbitrarily complex or nested objects as arguments, the recommended approach for CLI is to accept a JSON string: `complex_arg::'{"name": "item", "details": {"id": 10, "tags": ["a","b"]}}'`. The `kind` could be `JsonString` (parsed and validated as JSON, then passed as string) or `Object` (parsed into an internal map/struct representation). +* **`InputStream` / `OutputStream`**: Special kinds indicating the argument is not a simple value but a stream provided by `utility1` via `ExecutionContext`. + * `InputStream`: For reading data (e.g., from CLI stdin, HTTP request body). + * `OutputStream`: For writing data (e.g., to CLI stdout, HTTP response body). + * These are typically not specified directly on the CLI as `key::value` but are resolved by `utility1` based on context or special syntax (e.g., a command might define an argument `input_source` of kind `InputStream` which defaults to stdin if not otherwise bound). +* **`Any`**: Any type, minimal validation. Use sparingly. +* **Custom Types**: The system should be extensible to support custom types defined by `Extension Module`s, along with their parsing and validation logic. + +#### 2.3. Methods of Command Specification + +Commands can be defined in `unilang` through several mechanisms: + +1. **Compile-Time Declarative (e.g., Rust Proc Macros)**: Attributes on structures or functions generate command definitions at compile time. Offers performance and type safety. +2. **Run-Time Procedural (Builder API)**: Code uses a builder pattern to construct and register command definitions at runtime. Offers dynamic command generation. +3. **Compile-Time External Definition (e.g., YAML, JSON)**: An external file (e.g., `commands.yaml`) is parsed during the build process (e.g., Rust `build.rs`), generating code to include command definitions. +4. **Run-Time External Definition (e.g., YAML, JSON)**: An external file is loaded and parsed by `utility1` at startup or on-demand to register commands. Requires a mechanism to link routines (e.g., named functions in `Extension Module`s). + +#### 2.4. Unified Command Registry + +Regardless of the definition method, all commands are registered into a single, unified command registry within `utility1`. +* This registry is responsible for storing and looking up command definitions. +* It must ensure the uniqueness of command `FullName`s. Conflicts (e.g., two definitions for the same command name) must be resolved based on a clear precedence rule (e.g., compile-time definitions override runtime, or an error is raised during registration). +* The registry should support efficient lookup by `FullName` and listing commands by namespace. +* For compile-time defined commands, Perfect Hash Functions (PHF) can be used for optimal lookup speed. Runtime additions would use standard hash maps. + +--- + +### 3. Interaction Modalities + +`unilang` definitions are designed to drive various interaction modalities. `utility1` may start in a default modality (often CLI) or have its modality switched by a specific `unilang` command. + +#### 3.1. Common Principles Across Modalities + +* **Command Discovery**: All modalities should provide a way to list available commands and namespaces (e.g., `utility1 .`, `utility1 .files.`). +* **Help/Introspection**: Access to detailed help for commands and their arguments (e.g., `utility1 .files.copy ?`). The help system should provide structured data (see 3.2.6). +* **Argument Input**: Modalities provide appropriate mechanisms for users to input argument values based on their `kind` and other attributes. +* **Error Presentation**: Consistent and clear presentation of errors (validation errors, execution errors). See Section 4.2. +* **Output Handling**: Displaying command output in a way suitable for the modality, respecting `OutputData` structure (Section 4.2.1). + +#### 3.2. Command Line Interface (CLI) + +The primary interaction modality. + +##### 3.2.1. Syntax and Structure +As defined in Section 1. + +##### 3.2.2. Language Processing (Parsing, Validation) +Follows the multi-phase processing defined in Section 1.1. + +##### 3.2.3. Request Execution +Handled by the Interpreter / Execution Engine (Section 5). + +##### 3.2.4. Output Formatting + +The CLI supports various output formats for command results, controllable via a global argument (e.g., `utility1 output_format::json .some.command`). +* Formats: `text` (default), `json`, `yaml`, `table`. +* Command routines should return structured `OutputData` (Section 4.2.1) to facilitate this. +* **Raw Output**: If a command routine's `OutputData` has an `output_type_hint` that is not a common structured type (e.g., `text/plain`, `application/octet-stream`), or if the payload is a raw byte stream, the CLI modality should write this data directly to `stdout`, bypassing structured formatters like JSON/YAML. + +##### 3.2.5. Shell Completions + +`utility1` should be able to generate shell completion scripts (for Bash, Zsh, Fish, PowerShell, etc.). +* These scripts would provide completion for command names, namespaces, and argument names. +* For arguments with `Enum` type or known value sets (e.g., file paths), completions could extend to argument values. +* A command like `utility1 .system.completion.generate shell_type::bash` could be used. + +##### 3.2.6. Help System (`?`) Output + +* Invoking `utility1 .namespace.command.name ?`, `utility1 .namespace. ?`, or `utility1 .system.globals ?` should, by default, produce human-readable text for the CLI. +* However, the underlying help generation mechanism **must** be capable of producing structured data (e.g., JSON). This can be accessed via the global output format argument: `utility1 .namespace.command.name ? output_format::json`. +* This structured help output **should** include fields such as: + * `name` (full command/global arg name, or namespace path) + * `description` (hint) + * `arguments` (list of argument definitions, including their name, kind, hint, optionality, default value, aliases, validation rules) - for commands and global args. + * `examples` (list of usage examples) - for commands. + * `namespace_content` (if querying a namespace: list of sub-commands and sub-namespaces with their hints). + * `status`, `version`, `deprecation_message` (if applicable for the command/global arg). + +#### 3.3. Textual User Interface (TUI) + +* **Invocation**: May be the default modality for `utility1`, configured globally, or entered via a `unilang` command like `utility1 .modality.set target::tui`. +* **Presentation**: Uses terminal libraries (e.g., `ratatui`, `ncurses`) for interactive command browsing, argument input forms with validation, and output display. Consumes structured help (3.2.6) and `OutputData`/`ErrorData`. + +#### 3.4. Graphical User Interface (GUI) + +* **Invocation**: May be the default, configured, or entered via `utility1 .modality.set target::gui`. +* **Presentation**: Uses native GUI toolkits (Qt, GTK) or web-based technologies (Tauri, Electron) for menus, rich forms with widgets (file pickers, date selectors), and dedicated output/log views. Consumes structured help and `OutputData`/`ErrorData`. + +#### 3.5. Audio User Interface (AUI) + +* **Invocation**: May be the default, configured, or entered via `utility1 .modality.set target::aui`. +* **Presentation**: Uses speech-to-text for input, text-to-speech for output/prompts. Requires a Natural Language Understanding (NLU) layer to map spoken phrases to `unilang` commands and arguments. Consumes structured help and `OutputData`/`ErrorData` for synthesis. + +#### 3.6. WEB Endpoints + +Automatically generate a web API from `unilang` command specifications. The HTTP server component is typically initiated by a specific `unilang` command defined within `utility1` (often provided by an `Extension Module`). + +* **Goal**: Automatically generate a web API from `unilang` command specifications. +* **Invocation**: An HTTP server, potentially started by a user-defined command like `utility1 .server.start port::8080` or `utility1 .api.serve`. This `.server.start` command would itself be defined using `unilang` and its routine would be responsible for initializing and running the web server. The functionality might be provided by a dedicated `Extension Module` that `utility1`'s integrator includes. +* **Mapping Commands to Endpoints**: + * A `unilang` command `.namespace.command.name` maps to an HTTP path (e.g., `/api/v1/namespace/command/name`). The base path (`/api/v1/`) is configurable. Command path segments are typically used directly or converted to `kebab-case` in URLs if that's the API style. + * HTTP method determined by `http_method_hint` in command definition, then by inference (e.g., `get*`, `list*` -> `GET`; `create*`, `add*` -> `POST`; `update*` -> `PUT`; `delete*`, `remove*` -> `DELETE`), then defaults (e.g., `POST`). +* **Argument Passing & Data Serialization**: + * `GET`: Arguments as URL query parameters. + * `List` encoding: Repeated parameter names (e.g., `?list-arg=item1&list-arg=item2`). + * `Map` encoding: Bracketed notation (e.g., `?map-arg[key1]=value1&map-arg[key2]=value2`). + * `POST`, `PUT`, `PATCH`: Arguments as a JSON object in the request body. Argument names in `unilang` map to JSON keys (typically `camelCase` or `snake_case` by convention in JSON, conversion from `kebab-case` or `snake_case` argument names may apply). + * Binary data (e.g., file uploads for an `InputStream` argument) would use `multipart/form-data`. + * Responses are typically JSON, based on `OutputData` (Section 4.2.1) and `ErrorData` (Section 4.2). +* **Responses & Error Handling (HTTP specific)**: + * **Success**: Standard HTTP success codes (200 OK, 201 Created, 204 No Content). Response body (if any) is JSON derived from `OutputData.payload`. `OutputData.metadata` might be in headers or a wrapper object. + * **Error**: Standard HTTP error codes (400 Bad Request, 401 Unauthorized, 403 Forbidden, 404 Not Found, 500 Internal Server Error). Response body is a JSON object based on `ErrorData`. +* **API Discoverability (OpenAPI)**: + * An endpoint (e.g., `GET /api/v1/openapi.json` or `/api/v1/swagger.json`) automatically generates an OpenAPI (v3+) specification. + * This spec is derived from `unilang` command definitions (paths, methods, argument attributes mapping to parameters, `kind` mapping to schema types, hints to descriptions). +* **Asynchronous Operations**: + For long-running commands initiated via WEB Endpoints: + 1. Initial request receives `202 Accepted`. + 2. Response includes a `Location` header pointing to a status endpoint (e.g., `/api/v1/tasks/{task_id}`). + 3. Client polls the status endpoint, which returns current status (e.g., `Pending`, `Running`, `Success`, `Failure`) and potentially partial results or logs. + 4. Upon completion, the status endpoint can provide the final result or a link to it. + This requires `utility1` to have a task management subsystem. + +#### 3.7. `utility1://` URL Scheme (for utility interaction) + +* **Structure**: `utility1://[namespace_path/]command.name[?query_parameters]` +* Used for inter-application communication or custom protocol handlers invoking `utility1` CLI commands. +* Distinct from WEB Endpoints. Query parameters should follow standard URL encoding. + +--- + +### 4. Cross-Cutting Concerns + +#### 4.1. Path Handling + +* **URI-based Internal Representation**: Path-like arguments are internally converted to and handled as URIs (e.g., `file:///path/to/local`, `clipboard://`, `stdin://`, `temp://filename`). If no scheme is provided, `file://` is assumed. +* **Absolute Path Conversion**: For `file://` URIs, `utility1` resolves them to absolute paths based on the current working directory before passing them to command routines, unless a command explicitly requires relative paths. +* **Path Validation**: Can be specified via `validation_rules` (e.g., `exists`, `is_file`, `is_directory`, `is_readable`, `is_writable`). + +#### 4.2. Error Handling Strategy + +A standardized approach to errors is crucial for predictability. + +* **Command Routine Return**: Routines should return a `Result`. +* **`ErrorData` Structure**: + ```json + { + "code": "ErrorCodeIdentifier", // e.g., UNILANG_ARGUMENT_INVALID, MYAPP_CUSTOM_ERROR + "message": "Human-readable error message.", // utility1 may localize this + "details": { /* Optional: Object for error-specific details */ + // Example for UNILANG_ARGUMENT_INVALID: "argument_name": "src", "reason": "File does not exist" + // Example for UNILANG_SYNTAX_ERROR: "syntax_issue": "Unterminated quote", "sub_kind": "UnterminatedQuote" + "location_in_input": { // Describes where in the input the error was detected. + "source_type": "single_string" /* or "string_slice" */, + // If "single_string": + "start_offset": 15, // byte offset from the beginning of the single input string + "end_offset": 20, // byte offset for the end of the problematic span + // If "string_slice": + "segment_index": 2, // index of the string in the input slice + "start_in_segment": 5, // byte offset from the beginning of that segment string + "end_in_segment": 10 // byte offset for the end of the span within that segment + } + }, + "origin_command": ".files.copy" // Optional: FullName of the command that originated the error (if past parsing) + } + ``` +* **Standard Error Codes**: `utility1` implementations **should** use these core `unilang` error codes when applicable, and **may** define more specific codes. + * `UNILANG_COMMAND_NOT_FOUND` + * `UNILANG_ARGUMENT_INVALID` + * `UNILANG_ARGUMENT_MISSING` + * `UNILANG_TYPE_MISMATCH` + * `UNILANG_VALIDATION_RULE_FAILED` + * `UNILANG_PERMISSION_DENIED` + * `UNILANG_EXECUTION_ERROR` (Generic for routine failures) + * `UNILANG_EXTENSION_MODULE_ERROR` (Error originating from an Extension Module) + * `UNILANG_IO_ERROR` + * `UNILANG_MODALITY_UNAVAILABLE` + * `UNILANG_MODALITY_SWITCH_FAILED` + * `UNILANG_INTERNAL_ERROR` (For unexpected framework issues) + * `UNILANG_SYNTAX_ERROR` (For errors during Phase 1 lexical or syntactic analysis, e.g., unterminated quote, unexpected token, itemization failure. The `details` field may contain more specific sub-categories of the syntax issue.) +* **Modality Mapping**: Each modality translates `ErrorData` appropriately (e.g., CLI prints to stderr, WEB Endpoints map to HTTP status codes and JSON bodies). +* **`ErrorData` `details` Field**: + * This field provides context for the error. It **should** include `location_in_input` detailing where the error was detected, structured as shown above to reflect whether the input was a single string or a slice of strings, providing span information (e.g., start/end offsets). + * For `UNILANG_ARGUMENT_INVALID`, `UNILANG_ARGUMENT_MISSING`, `UNILANG_TYPE_MISMATCH`, `UNILANG_VALIDATION_RULE_FAILED`: `details` **should** include `argument_name: String`. + * For `UNILANG_COMMAND_NOT_FOUND`: `details` **may** include `attempted_command_name: String`. + * For `UNILANG_SYNTAX_ERROR`: `details` **should** include a description of the syntax issue and **may** include a more specific `sub_kind` (e.g., "UnterminatedQuote", "InvalidEscapeSequence", "ItemizationFailure"). + +#### 4.2.1. `OutputData` Structure +When a command routine succeeds, it returns `OutputData`. This structure facilitates consistent handling across modalities and `output_format` settings. +* **Structure**: + ```json + { + "payload": "Any", // The main command result (e.g., string, number, boolean, list, object). + // For commands producing no specific output on success (e.g., a 'set' operation), + // this can be null or a success message object like {"status": "success", "message": "Operation complete"}. + "metadata": { /* Optional: Object for additional information not part of the primary payload. + e.g., "count": _integer_, "warnings": [_string_], "pagination_info": _object_ */ }, + "output_type_hint": "String" // Optional: A MIME type like "application/json" (default if payload is object/array), + // "text/plain", "application/octet-stream". + // Helps modalities (especially CLI and WEB) decide on formatting. + // If payload is raw bytes and this is "application/octet-stream", + // formatters like JSON/YAML are bypassed. + } + ``` + +#### 4.3. Security Considerations + +##### 4.3.1. Input Sanitization & Validation + +* `unilang`'s type system (`kind`) and `validation_rules` provide a first line of defense. +* Command routines are ultimately responsible for ensuring inputs are safe before use, especially if interacting with shells, databases, or other sensitive systems. Avoid constructing scripts or queries by direct string concatenation of user inputs. +* For `Path` arguments, be cautious about path traversal vulnerabilities if not using the resolved absolute paths. + +##### 4.3.2. Permissions & Authorization Model + +* The `permissions` attribute in a command definition declares the necessary rights. +* `utility1`'s execution core or specific modalities (like WEB Endpoints) must implement an authorization mechanism that checks if the invoking user/context possesses these permissions. +* The permission strings are abstract; their meaning and how they are granted/checked are implementation details of the `utility1` environment. + +##### 4.3.3. Sensitive Data Handling + +* Arguments marked `sensitive: true` require special handling: + * CLIs should mask input (e.g., password prompts). + * GUIs/TUIs should use password fields. + * Logs should redact or omit these values (see Section 4.6). + * Care should be taken not to inadvertently expose them in error messages or verbose outputs. + +##### 4.3.4. WEB Endpoint Security + +If `utility1` exposes WEB Endpoints, standard web security practices apply: +* Use HTTPS. +* Implement authentication (e.g., API keys, OAuth2/OIDC tokens). +* Protect against common vulnerabilities (CSRF, XSS, SQLi - if applicable, SSRF). +* Implement rate limiting and request size limits. +* The OpenAPI specification should accurately reflect security schemes. + +#### 4.4. Configuration of `utility1` + +`utility1` itself may require configuration, affecting `unilang` behavior. +* **Configuration Sources & Precedence**: The listed order of sources **is** the strict precedence order. Items later in the list (higher precedence) override values from earlier items. + 1. Default built-in values. + 2. System-wide configuration file (e.g., `/etc/utility1/config.toml`). + 3. User-specific configuration file (e.g., `~/.config/utility1/config.toml`). + 4. Project-specific configuration file (e.g., `./.utility1.toml` in the current directory). + 5. Environment variables (e.g., `UTILITY1_LOG_LEVEL`). + 6. CLI Global Arguments to `utility1` (e.g., `utility1 log_level::debug ...`). +* **Configurable Aspects**: + * `Extension Module` search paths or integration settings (if applicable beyond build system dependencies). + * Default log level (Section 4.6). + * Default output format for CLI. + * Paths for i18n resource bundles (if `utility1` supports localization). + * WEB Endpoint server settings (port, base path, SSL certs). + * Authentication provider details for WEB Endpoints. + +#### 4.5. Extensibility: Compile-Time Modalities & Hybrid Command Model + +`unilang` and `utility1` are designed for extensibility. This is achieved through: +1. **Compile-Time `Extension Module`s:** For defining core functionalities, representation modalities, and a base set of commands. +2. **Run-Time Command Registration:** For dynamically adding new commands after `utility1` has been compiled and is running. + +* **A. Compile-Time `Extension Module` Capabilities (Guidance for Integrators)** + * `utility1` can be structured such that different internal modules or dependent crates (acting as compile-time **`Extension Module`s**) contribute: + * **Representation Modalities**: Implementations for UI modalities (CLI, TUI, GUI, WEB server logic, etc.) and any modifications or themes for them. These are fixed at compile time. + * **Core Commands & Types**: A foundational set of `unilang` Command Definitions (as per Section 2) and custom Argument Types (`kind` as per Section 2.2.2). These are registered into `utility1`'s unified registries during the compilation process (e.g., via procedural macros, build scripts). + * **Core Routines**: The implementations (handler functions) for these compile-time commands. + +* **B. Run-Time Command Extensibility** + * `utility1` **must** provide a mechanism for new **Command Definitions** to be added to its unified command registry *at run-time*. + * This allows extending `utility1`'s capabilities without recompilation, for example, by: + * Loading command definitions from external files (e.g., YAML, JSON) at startup or on-demand. + * Receiving command definitions from other processes or over a network (if `utility1` implements such an interface). + * A procedural API within `utility1` (if it's embeddable or has an interactive scripting layer) to define and register commands dynamically. + * **Important Note:** Only commands can be added at run-time. Representation modalities and custom argument types (`kind`) are fixed at compile time via **`Extension Module`s**. If a run-time defined command requires a custom argument type not known at compile-time, it must use existing types or more generic ones like `String` or `JsonString` and perform more specific parsing/validation within its routine. + +* **`Extension Module` Integration (Compile-Time Part - Integrator's Responsibility)**: + * The mechanism by which `utility1` incorporates compile-time **`Extension Module`s** is a standard part of its build system (e.g., `Cargo.toml` dependencies). + +* **Manifests (For `Extension Module`s & Potentially for Run-Time Definitions)**: + * **`Extension Module`s**: May internally use manifest-like structures for organization or to aid code generation (e.g., `module_name`, `module_version`, `unilang_spec_compatibility`, `description`, `author`, `license`, `entry_points` for `unilang` components). The `entry_points` values are strings whose interpretation is specific to `utility1`'s build/integration mechanism. + * **Run-Time Command Definition Files**: External files (e.g., YAML/JSON) defining commands for run-time loading act as a form of manifest for those commands. They should adhere to the `unilang` `CommandDefinition` structure. + +* **Component Registration**: + * **Compile-Time**: `utility1`'s build process or initialization code collects and registers all `unilang`-compatible components (modalities, core commands, types) from its constituent compile-time **`Extension Module`s** into the relevant `unilang` registries. (Mechanisms: procedural macros, build scripts, static initializers). + * **Run-Time (Commands Only)**: `utility1` **must** expose an API or mechanism to add `CommandDefinition` structures to its live, unified command registry. This API would also need a way to associate these commands with their executable routines. + * For routines of run-time loaded commands: + * If loaded from external files, the `routine_link` (Section A.1) might point to a function in an already loaded (compile-time) **`Extension Module`**, or to a script to be executed by an embedded interpreter (if `utility1` supports this). + * If defined procedurally at run-time, the routine is typically provided directly as a closure or function pointer. + +* **Security**: + * **Compile-Time `Extension Module`s**: Trust is based on the `utility1` build process and vetting of dependencies. + * **Run-Time Commands**: If `utility1` loads command definitions or executes routines from untrusted sources at run-time, the integrator is responsible for implementing robust security measures (sandboxing, permission checks for command registration, validation of definition sources). `unilang`'s permission attributes on commands can be leveraged here. + +#### 4.6. Logging (Guidance for `utility1` and Routines) + +A consistent logging strategy is essential for debugging and auditing. `utility1` should provide a logging facility accessible to command routines via the `ExecutionContext`. + +* **Logging Facade**: `utility1` should use or provide a common logging facade. +* **Log Levels**: Standard levels (e.g., `TRACE`, `DEBUG`, `INFO`, `WARN`, `ERROR`). +* **Configurable Log Level**: The active log level for `utility1` and its routines should be configurable (see Section 4.4, e.g., via global argument `log_level::debug`). +* **Structured Logging**: It is recommended that `utility1`'s logging output be structured (e.g., JSON format) to include timestamp, level, module/command name, message, and contextual key-value pairs. +* **Sensitive Data Redaction**: `utility1`'s logging system or conventions for routines should ensure that arguments marked `sensitive: true` are automatically redacted or omitted from logs. +* **Audit Logging**: For critical operations or WEB Endpoints, `utility1` may implement dedicated audit logs. + +#### 4.7. Execution Context + +An `ExecutionContext` object **is always** passed to command routines by `utility1` alongside `VerifiedCommand`. Its specific content is defined by `utility1` but **should** provide access to at least: + +* The current effective global argument values (e.g., `output_format`, `log_level`). +* Access to `utility1`'s configuration settings. +* A pre-configured logger instance (respecting current log level and command context). +* (If applicable for streaming kinds like `InputStream`/`OutputStream`) Methods to acquire input/output streams connected to the appropriate source/sink for the current modality. +* Information about the invoking modality. +* (If `utility1` supports localization) The current active locale. + +#### 4.8. Command Sequences and Atomicity (` ;; `) + +* Commands separated by `;;` are executed sequentially. +* By default, if a command in the sequence fails, subsequent commands are not executed. This behavior can be controlled by a global argument (e.g., `on_error::continue`). +* `unilang` itself does not define transactional semantics for command sequences. Each command is typically treated as an independent operation. If a `utility1` implementation or a specific set of commands offers transactional guarantees, this is an extension beyond the core `unilang` specification. + +--- + +### 5. Interpreter / Execution Engine + +The Interpreter, also referred to as the Execution Engine, is the component within `utility1` responsible for taking a `VerifiedCommand` (or a sequence thereof) produced by the preceding parsing and semantic analysis phases (Section 1.1), and orchestrating the execution of its associated `Routine (Handler Function)`. + +#### 5.1. Core Responsibilities + +1. **Routine Invocation:** + * For each `VerifiedCommand`, the Interpreter retrieves the linked `Routine` from the `CommandDefinition`. + * It prepares and passes the `VerifiedCommand` object (containing resolved and typed arguments) and the `ExecutionContext` object (Section 4.7) to the `Routine`. + +2. **Handling Routine Results:** + * The Interpreter receives the `Result` returned by the `Routine`. + * If `Ok(OutputData)`: The `OutputData` is passed to the current `Modality` for presentation to the user (respecting global arguments like `output_format`). + * If `Err(ErrorData)`: The `ErrorData` is passed to the current `Modality` for error reporting. + +3. **Sequential Command Execution (` ;; `):** + * If the input resulted in a sequence of `VerifiedCommand`s, the Interpreter executes them in the specified order. + * It respects the `on_error` global argument policy (e.g., `stop` (default) or `continue`) when a command in the sequence returns `ErrorData`. + +4. **`ExecutionContext` Management:** + * The Interpreter is responsible for creating and populating the `ExecutionContext` that is passed to each `Routine`. This context may be updated between commands in a sequence if necessary (though typically, global settings from `ExecutionContext` are established at the start of the entire `utility1` invocation). + +5. **Resource Management (Basic):** + * While complex resource management is `utility1`'s broader concern, the Interpreter might handle basic setup/teardown around routine execution if required by the `unilang` framework (e.g., related to `InputStream`/`OutputStream` arguments). + +#### 5.2. Interaction with Modalities + +* The Interpreter does not directly handle user input or output rendering. It delegates these tasks to the active `Modality`. +* The Modality is responsible for: + * Providing the initial CLI string (for CLI modality) or equivalent user interaction data. + * Displaying `OutputData` in a user-appropriate format. + * Presenting `ErrorData` clearly. + * Handling interactive prompts if an argument is marked `interactive` and a value is missing (this interaction might loop back through parts of the semantic analysis). + +#### 5.3. Extensibility + +* The core Interpreter logic is part of the `unilang` framework provided by the crate. +* `utility1` integrators influence its behavior by: + * Registering commands with their specific `Routine`s. + * Defining the content and services available via `ExecutionContext`. + * Implementing the presentation logic within their chosen `Modality` handlers. + +--- + +### 6. Appendices + +#### A.1. Example `unilang` Command Library (YAML) + +This appendix provides an example of how commands might be defined in a YAML file.

BNF or Formal Grammar for CLI Syntax (Simplified) + +This is a simplified, illustrative Backus-Naur Form (BNF) style grammar. A full grammar would be more complex, especially regarding value parsing and shell quoting. This focuses on the `unilang` structure. + +```bnf + ::= + + ::= | "" + ::= + ::= | "" + + ::= + ::= | "" + ::= ";;" + + ::= + | + | (* . or .? *) + + ::= + ::= | "" + ::= "." "." (* e.g., .files.utils. *) + ::= (* e.g. .files. *) + ::= "." + + ::= + ::= "." | "" + ::= (* command or namespace segment: lowercase alphanumeric + underscore *) + + ::= (* The full path-like name of the command *) + + + ::= | "" + ::= + ::= | "" + + ::= | + + ::= "::" + ::= (* kebab-case or snake_case *) + + ::= (* positional, parsed as default arg if one is defined *) + + ::= | +(* Actual value parsing is type-dependent and complex, involving list/map separators, etc. *) +(* would be [a-z0-9_]+ *) +(* would be [a-z0-9_-]+ *) +(* handles spaces and special characters. Unescaped content is used. *) + + ::= | "" + ::= "?" +``` + +**Notes on this BNF:** + +* It's high-level and conceptual. +* `utility_name` is the literal name of the utility (e.g., `utility1`). +* `` and `` need precise definitions based on allowed characters (Section 2.1). +* `` parsing is the most complex part and is abstracted here. It represents the unescaped content after initial lexing and quote processing. +* Shell quoting and escaping are handled by the shell before `utility1` receives the arguments. `unilang`'s parser then handles its own quoting rules. + +**Note on Applying Grammar to Dual Input Types:** + +This BNF describes the logical structure of a `unilang` command expression. +* When parsing a **single string input**, the parser attempts to match this grammar directly against the character stream. +* When parsing a **slice of strings input** (pre-tokenized by the shell), the parser consumes these strings sequentially. Each string (or parts of it, if a string contains multiple `unilang` elements like `name::value`) is then matched against the grammar rules. For instance, one string from the slice might be an ``, the next might be `::` (if the shell separated it), and the next an ``. Or a single string from the slice might be `name::value` which the `unilang` parser then further decomposes. The parser must be able to stitch these segments together to form complete `unilang` syntactic structures as defined by the grammar. + +--- + +#### A.3. Component Registration (Conceptual Outline for Hybrid Model) + +This appendix outlines the conceptual mechanisms for how `unilang` components are registered within `utility1`, covering both compile-time contributions from **`Extension Module`s** and run-time command registration. The `noun_verb` convention is used for conceptual API method names that `utility1` might expose for run-time operations. + +**1. Compile-Time Component Registration (Modalities, Core Commands from `Extension Module`s, Types)** + +`Extension Module`s providing modalities, core commands, or custom types need to make their definitions available to `utility1`'s central registries at compile time. + +* **A. Information Required for Modality Registration (Compile-Time Only via `Extension Module`s)** + * An **`Extension Module`** providing a modality (e.g., a TUI implementation) needs to register its handler or main entry point with `utility1`. + * **Mechanism Examples**: Static registration where `utility1`'s build system links modality implementations from known `Extension Module`s. `utility1` might discover modules that implement a `utility1`-defined `ModalityHandler` trait/interface. + +* **B. Information Required for Core Command Registration (Compile-Time via `Extension Module`s)** + * `Extension Module`s make `CommandDefinition` structures (Section 2.1) available. + * **Mechanisms**: Procedural macros within `Extension Module`s, static arrays of `CommandDefinition` collected by `utility1`'s build script, or build script code generation that reads module-specific definitions. Routines are typically static function pointers. + +* **C. Information Required for Custom Type Registration (Compile-Time Only via `Extension Module`s)** + * `Extension Module`s make `CustomTypeDefinition` structures available. + * `CustomTypeDefinition` includes `type_name`, static `parser_function`, static `validator_function`, and `help_info`. + * **Mechanisms**: Similar to command registration (macros, static collections, build script generation). Custom types cannot be added at run-time. + +**2. Run-Time Command Registration (Commands Only)** + +`utility1` **must** provide a run-time API or mechanism to add new `CommandDefinition`s to its existing unified command registry. + +* **A. Procedural Run-Time API (Example using `noun_verb` convention)** + * `utility1` could expose methods like: + * `fn command_add_runtime(definition: unilang::CommandDefinition, routine: Box Result + Send + Sync>) -> Result<(), RegistrationError>` + * `fn command_remove_runtime(command_name: &str) -> Result<(), UnregistrationError>` (Optional) +* **B. Loading from External Definitions (e.g., YAML/JSON)** + * `utility1` might have a built-in command or mechanism: `utility1 .system.commands.load.file path::/path/to/commands.yaml` + * The loaded `CommandDefinition`s would need their `routine_link` attribute to be resolvable by `utility1`. This could mean the `routine_link` refers to a function symbol within `utility1` itself or one of its compile-time loaded **`Extension Module`s**, or a script function if `utility1` embeds a scripting engine. +* **C. Command Routine Signature (Expected by `unilang` via `utility1`)** + * `fn routine_handler(verified_command: VerifiedCommand, exec_context: ExecutionContext) -> Result` + +**3. Access to `utility1` Services (via `ExecutionContext`)** +* The `ExecutionContext` (Section 4.7) is prepared by `utility1` and passed to all routines, whether linked at compile-time or run-time. + +**Example (Conceptual Rust-like Trait for an `ExtensionModule` Interface `utility1` might expect for compile-time contributions):** + +```rust +// Conceptual - This is what a utility1 integrator might define for its Extension Modules. + +// Provided by utility1 to the Extension Module during a compile-time collection phase +// (e.g. via build script or macro that calls an ExtensionModule's registration function) +pub trait ExtensionModuleRegistrationContext { + // Uses noun_verb for consistency with potential runtime APIs + fn command_add(&mut self, definition: unilang::CommandDefinition) -> Result<(), String>; + fn type_define(&mut self, type_def: unilang::CustomTypeDefinition) -> Result<(), String>; + // Modalities would likely be registered differently, perhaps by utility1 discovering + // modules that implement a ModalityHandler trait and are linked at compile time. +} + +// Implemented by the Extension Module +pub trait UnilangExtensionModule { + // Manifest-like information, could be static or methods + fn module_name(&self) -> &'static str; + fn unilang_compatibility(&self) -> &'static str; // e.g., ">=1.0.0 <2.0.0" + + // Method called by utility1's build system/macros to collect definitions + fn components_register(&self, context: &mut dyn ExtensionModuleRegistrationContext) -> Result<(), String>; +} diff --git a/module/move/unilang/src/ca/mod.rs b/module/move/unilang/src/ca/mod.rs new file mode 100644 index 0000000000..17a13217fb --- /dev/null +++ b/module/move/unilang/src/ca/mod.rs @@ -0,0 +1,12 @@ +//! +//!

fundamental symbols. +* **Key Testing Factors:** + * **Token Recognition:** + * Correctly tokenizes identifiers (command/namespace segments, argument names). + * Correctly tokenizes `::` (KeyValueSeparator). + * Correctly tokenizes `;;` (CommandSeparator). + * Correctly tokenizes `?` (HelpOperator). + * Correctly tokenizes argument values: + * Unquoted values (simple strings, numbers). + * Single-quoted values (preserving internal spaces/symbols). + * Double-quoted values (preserving internal spaces/symbols). + * Values with escaped quotes within quoted strings. + * **Whitespace Handling:** + * Whitespace between tokens is correctly ignored. + * Whitespace within unquoted argument values (should typically delimit them or be part of a single token depending on rules). + * Leading/trailing whitespace in the input string. + * **Edge Cases & Errors:** + * Empty input string. + * Input string with only whitespace. + * Unrecognized characters/symbols (generates an error token or specific error). + * Unterminated quoted strings (generates an error). +* **Test Relevance/Acceptance Criteria:** + * All specified token types are correctly identified and produced

Factors:** + * **AST/Generic Instruction Structure:** + * Correct structure for a single command with no arguments. + * Correct structure for a command with only positional/default arguments. + * Correct structure for a command with only named arguments. + * Correct structure for a command with mixed positional and named arguments. + * Correct structure for a command with the help operator (`?`). + * Correct structure for a namespace help request (e.g., `.files. ?`). + * Correct structure for a root namespace help request (`. ?` or `.`). + * **Command Path Parsing:** + * Correctly parses dot-separated command `FullName`s (e.g., `.namespace.sub.command`). + * Handles root namespace commands (e.g., `.command`). + * **Argument Parsing (Syntactic):** + * Correctly associates `arg_name` with `arg_value` for named arguments. + * Correctly identifies sequence of `arg_value`s as potential positional arguments. + * **Command Sequence Parsing:** + * Correctly parses multiple command expressions separated by `;;` into a sequence of AST nodes/Generic Instructions. + * **Error Handling:** + * Unexpected token errors (e.g., `::` without a preceding argument name). + * Missing components (e.g., argument value after `::`). + * Misplaced `;;` or `?`. + * **Boundary Conditions:** + * Empty token stream (after lexing empty input). + * Very long sequences of commands. +* **Test Relevance/Acceptance Criteria:** + * Valid token streams produce a correct and complete AST/Generic Instruction sequence. + * Syntactic errors in the token stream result in specific and actionable parse errors. + * All `unilang` grammar rules (as per Appendix A.2) are correctly implemented. +* **Key Code Modules/Areas to Cover:** + * Parser module (`src/parser/parser.rs` or similar). + * AST node definitions or Generic Instruction struct definitions. + * Parser error types. + * Integration with the Lexer module. + +#### Feature 2.3: Global Argument Identification & Extraction Logic +* **Description:** Framework logic for integrators to define and extract their global arguments from the initial part of the CLI string, before command expression parsing. +* **Key Testing Factors:** + * Correctly identifies and extracts `key::value` pairs as global arguments if they appear before the first command path. + * Stops consuming tokens as global arguments once a token that cannot be part of a global argument (e.g., a command path segment starting with `.`, or `?`, or `;;` if no command preceded) is encountered. + * Handles multiple global arguments. + * Handles cases with no global arguments (passes entire input to command parser). + * Provides a mechanism for the integrator to: + * Specify which keys are recognized as global arguments. + * Receive the extracted raw string key-value pairs. + * Behavior with malformed global arguments (e.g., `global_key_only::`). + * Behavior with unrecognized global argument keys (e.g., error if strict, or pass-through to command parsing if lenient – to be defined by `unilang`'s strictness here). +* **Test Relevance/Acceptance Criteria:** + * Integrator-defined global arguments are correctly identified and their raw string values are made available. + * The remaining token stream (for command expressions) is correctly passed to the main parser. + * Errors are handled appropriately for malformed or (if strict)

Simpler: `strs_tools::Item` remains as is. The `unilang_instruction_parser::ParseError` created during syntactic analysis will need to know which original segment an `Item` came from to build the final `SourceLocation`.* + * *Revised approach for `parse_slice` item location:* The `strs_tools::Item<'a>` will have locations relative to their individual segment. The `analyze_items_to_instructions` function will need to be aware of segment boundaries if it needs to report errors spanning multiple original segments, or the `Parser` will need to pass `seg_idx` to error creation. For now, assume `analyze_items_to_instructions` receives a flat `Vec>` and error locations are based on these items' local spans. The final `ParseError` constructor will need `seg_idx` if the error is tied to an item from a slice. + * A simpler way for `parse_slice`: itemize each segment, then in `analyze_items_to_instructions`, if an error occurs with an `Item`, its original `item.location` (from `strs_tools`) is used along with the `segment_index` (which needs to be tracked alongside items from slices) to form the `SourceLocation::SliceSegment`. + * Pass the combined `Vec>` (potentially with segment origin info) to `analyze_items_to_instructions`. + * Detailed Plan Step 7: Add basic tests for `parse_single_str` and `parse_slice` (empty input, single command name). + * Relevant Behavior Rules: E0, E9, E10. + * Verification Strategy: `cargo test --package unilang_instruction_parser`. + * Commit Message: `feat(unilang_parser): Impl parser config, entry points, and initial input handling` + +* ⚫ **Increment 3: Syntactic Analyzer - Command Structure (Path, Help, Command Separation)** + * Target Crate(s): `unilang_instruction_parser` + * Detailed Plan Step 1: In `parser_engine.rs`, implement `fn analyze_items_to_instructions<'input>(&self, items: Vec>, input_origin: InputOrigin /* enum { SingleStr, Slice(&'input [&'input str]) } */ ) -> Result>, ParseError>`.

The `analyze_items_to_instructions` might need to receive items as `Vec<(Item<'input>, Option/*seg_idx*/)>` or the `Parser` needs a way to map a global item index back to its original segment if `parse_slice` flattens everything. + * *Decision for Slice Location:* `parse_slice` should probably not flatten items immediately. It could call `analyze_items_to_instructions` per segment, or `analyze_items_to_instructions` needs to be more aware. A simpler start: `parse_slice` itemizes segment by segment. If an itemization error occurs within a segment, its location is already relative. If a syntactic error occurs later with items from a slice, the `Item` itself should carry enough info (or be wrappable) to trace back to its original segment_index and its local location. + * *Revised approach for Slice Location in `analyze_items_to_instructions`*: The `Item` struct from `strs_tools` only has `start/end` byte offsets. When `parse_slice` calls `itemize_all` on each segment, it gets `Item`s whose locations are relative to *that segment*. `parse_slice` must then transform these `Item`s (or wrap them) to include the `segment_index` before passing them to a flattened analysis stage, OR the analysis must happen per-segment and results aggregated. + * **Let's simplify:** `analyze_items_to_instructions` takes `items: Vec>` and `segment_index: Option`. `parse_single_str` calls it with `None`. `parse_slice` calls it for *each segment's items* with `Some(seg_idx)`. This means `analyze_items_to_instructions` might produce partial `GenericInstruction`s if a unilang command spans multiple shell arguments, which then need to be stitched together. This is getting complex. + * **Alternative for `parse_slice`:** Concatenate all string segments from the slice into one temporary owned `String` (with a special, non-printable separator if needed to map locations back accurately, or by tracking original segment lengths). Then parse this single string. This simplifies location tracking to always be `StrSpan` but introduces an allocation and copying. + * **Chosen Path (Compromise):** `parse_slice` will itemize each segment. The `Vec>` passed to `analyze_items_to_instructions` will be flat. Each `Item` needs to be augmented or wrapped to carry its original `segment_idx`. + ```rust + // In unilang_instruction_parser, perhaps in input_adapter.rs or alongside Item + struct RichItem<'a> { + inner: strs_tools::string::parser::Item<'a>, + segment_idx: Option, // None for single_str input + } + ``` + `analyze_items_to_instructions` works on `Vec>`. + * Verification Strategy: Tests for errors in both input modes, checking `ParseError.location`. + * Commit Message: `fix(unilang_parser): Integrate SourceLocation for precise error reporting` + +* ⚫ **Increment 6: Comprehensive Test Suite (Test Matrix)** + * (As per previous plan: cover input types, command structures, arg types, value types, delimiters, operators, quoting, errors, edge cases). + * Verification Strategy: `cargo test --package unilang_instruction_parser --all-features`. + * Commit Message: `test(unilang_parser): Implement comprehensive test suite` + +* ⚫ **Increment 7: Documentation and Examples** + * (As per previous plan: crate-level, public API docs, example file). + * Verification Strategy: Manual review, `cargo test --doc --package unilang_instruction_parser`. + * Commit Message: `docs(unilang_parser): Add documentation and examples` + +## Requirements (for `unilang_instruction_parser` - Expanded) +* **R1: Dependency on `strs_tools::string::parser`:** Must use the itemizer from `strs_tools`. +* **R2: Unilang Specific Syntax:** Syntactic analyzer implements `unilang` grammar from spec. +* **R3: Dual Input Handling & Abstraction:** Public API supports `&str` and `&[&str]`. Internal logic must correctly map locations for both. +* **R4: Value Unescaping:** Argument values in `GenericInstruction` must be unescaped, likely using `Cow<'a, str>`. +* **R5: Precise Location-Aware Errors:** `ParseError` uses `SourceLocation` (distinguishing `StrSpan` and `SliceSegment`). +* **R6: No Command Definitions Dependency:** Purely syntactic. +* **R7: Comprehensive Test Coverage:** Including Test Matrix for various scenarios. +* **R8: Adherence to Workspace Rules:** Standard project cargo command rules. +* **R9: API Clarity:** Public API of `unilang_instruction_parser` is clear. +* **R10: Correct `ItemizerOptions` Configuration:** `Parser::new()` must correctly configure `strs_tools::ItemizerOptions` for `unilang`'s specific lexemes (quotes, escapes, delimiters, operators, comments). +* **R11: Handling of `strs_tools` Items:** The syntactic analyzer must correctly interpret the stream of `strs_tools::Item`s, typically ignoring `Whitespace` and `PotentialComment` kinds. +* **R12: Lifetime Management:** All `&'a str` and `Cow<'a, str>` in output structures must correctly borrow from the original input. +* **R13: Error Propagation:** Errors from `strs_tools::Itemizer` must be cleanly converted and propagated as `unilang_instruction_parser::ParseError`. + +## Notes & Insights +* The `strs_tools::string::parser::Item` struct should ideally contain `kind: ItemKind` where `ItemKind` itself can store the matched delimiter/operator string (e.g., `Delimiter(&'static str)`), making the `unilang_parser`'s job easier. This was noted for the `strs_tools` plan. +* The most complex part of this new plan is handling `SourceLocation` correctly, especially when itemizing `&[&str]` and then performing syntactic analysis on a potentially flattened list of `RichItem`s. The `RichItem` wrapper approach seems like a good way to associate `segment_idx` with items originating from slices. +* The decision for `Argument::value` to be `Cow<'a, str>` (unescaped) is a good balance for correctness and performance. + +This revised plan for `unilang_instruction_parser` is more detailed about its interaction with `strs_tools` and the challenges of dual input source location tracking. \ No newline at end of file diff --git a/module/move/unilang_instruction_parser/src/config.rs b/module/move/unilang_instruction_parser/src/config.rs new file mode 100644 index 0000000000..99fa53f428 --- /dev/null +++ b/module/move/unilang_instruction_parser/src/config.rs @@ -0,0 +1,48 @@ +//!
