formatting rules to be applied. These rules should cover aspects such as: + * **Indentation:** Use 4 spaces for indentation. + * **Line Length:** Aim for a maximum line length of 100 characters. Break lines logically if they exceed this limit. + * **Spacing:** + * Single space around operators (`=`, `+`, `-`, `*`, `/`, `==`, `!=`, `<`, `>`, `<=`, `>=`, `&&`, `||`, etc.). + * Single space after commas and colons in lists, tuples, function arguments, etc. + * No space before commas, colons, or semicolons. + * Single space after keywords like `if`, `for`, `while`, `match`, `fn`, `let`, `use`, etc. + * Space between function name and parentheses (`fn my_func()`). + * No space between macro name and exclamation mark/parentheses (`my_macro!()`). + * **Brace Placement:** Use K&R style (opening brace on the same line as the control structure, closing brace on its own line). + * **Imports (`use` statements):** + * Group imports by category (e.g., standard library, external crates, local modules). + * Sort imports alphabetically within each group. + * Use glob imports (`*`) sparingly, preferably only in test modules or prelude-like modules. + * **Comments:** + * Use `//` for line comments and `/* ... */` for block comments. + * Ensure comments are properly indented and aligned with the code they refer to. + * Add a space after `//` for readability. + * **Blank Lines:** Use blank lines to separate logical blocks of code, such as between function definitions, struct definitions, or within functions to separate distinct operations. + * **Attributes:** Place attributes on the line immediately preceding the item they apply to. +2. **Apply Formatting to Each File:** + * Go through each `.rs` file listed above. + * Manually apply the defined formatting guidelines to the code in each file. + * Pay close attention to consistency across all files and crates. +3. **Review and Verify:** + * After applying the formatting, review the changes in each file. + * Consider using a diff tool to compare the formatted code with the original to easily spot any unintended changes or inconsistencies. + * Occasionally, if a linter is available and permitted, run it to catch any formatting issues that might have been missed. + * Ensure that the formatting changes have not altered the code's logic or functionality. + +This plan requires careful manual work but ensures that the formatting adheres to the specified guidelines without using `cargo fmt`. \ No newline at end of file diff --git a/module/core/component_model/src/lib.rs b/module/core/component_model/src/lib.rs index 8736456366..3936f30cfb 100644 --- a/module/core/component_model/src/lib.rs +++ b/module/core/component_model/src/lib.rs @@ -1,10 +1,90 @@ - +#![ 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/component_model/latest/component_model/" ) ] #![ 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. + +// xxx : add to readme example with enums +// xxx : disable and phase out attribute "[ perform( fn method_name<...> () -> OutputType ) ]" +// xxx : split out crate component model +// xxx : fix commented out tests + +/// Namespace with dependencies. +#[ cfg( feature = "enabled" ) ] +pub mod dependency +{ + pub use component_model_types;

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. - -## 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 implicit `VariantFormer`. `#[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. +# Project Plan: Remove Component Model Derives from Former Crates + +## Original Goal + +Remove derives FromComponents, ComponentsAssign, ComponentAssign and ComponentFrom from crates former, former_meta, former_types as well as documentations, examples, types and everything related to these derives and component model.

(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. + +## Notes & Insights + +* *(This section must always be present and preserved)* +* **[Date/Inc #] Struggling Point:** Unable to locate proc-macro definitions or attributes using initial search patterns in `module/core/former_meta/src`.

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. diff --git a/module/core/former/plan.template.md b/module/core/former/plan.template.md new file mode 100644 index 0000000000..5b6d13ade7 --- /dev/null +++ b/module/core/former/plan.template.md @@ -0,0 +1,13 @@ +# Project Plan: Fix Failing Former Enum Tests + +## Initial Task + +Check crates at +- module/core/former +- module/core/former_meta +- module/core/macro_tools + +Before starting analyze ALL sources at module/core/former_meta/src + +Strictly follow code/gen, design rules and codestyle rules and prioritize it over codestyle and design used in repository.

This maintains the core `FormerField` definition and simpler methods together while improving maintainability of the complex parts. +* **[Date/Increment 1] Insight:** Splitting `former_enum.rs` primarily involves extracting the large `generate_implicit_former_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.

The previous attempt to implement -// `generics_of_type` demonstrated this difficulty, leading to compilation errors. +// This macro implements the `Former` derive for enums based on the following consistent rules. +// Each case is handled by a specific function as noted: // -// 2. **Focus on Propagating Enum Generics:** The correct approach is to focus on the generics -// defined *on the enum itself*.
