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.

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 099/111] 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.
