This example defines a `Person` struct +//! and implements the `Assign` trait for its fields. It shows how to use these implementations to set the fields of a `Person` +//! instance using different types that can be converted into the required types. +//! +//! ## Explanation +//! +//! - **Person Struct**: The `Person` struct has two fields: `age` (an integer) and `name` (a string). The `Default` and `PartialEq` traits are derived to facilitate default construction and comparison. +//! +//! - **Assign Implementations**: The `Assign` trait is implemented for the `age` and `name` fields of the `Person` struct. +//! - For `age`: The trait is implemented for any type that can be converted into an `i32`. +//! - For `name`: The trait is implemented for any type that can be converted into a `String`. +//! +//! - **Usage**: An instance of `Person` is created using the default constructor, and then the `assign` method is used to set the `age` and `name` fields. +//! - `got.assign( 13 )`: Assigns the integer `13` to the `age` field. +//! - `got.assign( "John" )`: Assigns the string `"John"` to the `name` field. +//! + +#[ cfg( any( not( feature = "types_component_assign" ), not( feature = "enabled" ) ) ) ] +fn main() {} + +#[ cfg( all( feature = "types_component_assign", feature = "enabled" ) ) ] +fn main() +{ + use component_model_types::Assign;

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

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: Verify Former Derive for Tuple Enum Variants (Incremental Activation) + +## Goal +* Ensure the `#[derive(Former)]` macro correctly generates the expected constructors and subformers for **tuple enum variants** (`V()`, `V(T1)`, `V(T1, T2, ...)`) according to the defined behavior rules. +* Verify the implementation handles `#[scalar]`, `#[subform_scalar]`, `#[standalone_constructors]`, and `#[arg_for_constructor]` attributes correctly for tuple variants. +* **Incrementally activate** and ensure relevant tuple variant tests pass, grouping related `_derive`, `_manual`, and `_only_test` files for each variant type. **Verify manual tests pass before activating corresponding derive tests.** +* Keep tests related to unit or struct enum variants commented out. +* Add the Tuple Variant Test Matrix documentation to `former_enum_tests/mod.rs` while **preserving the existing matrix documentation**. +* Ensure all code modifications adhere strictly to `code/gen` instructions, Design Rules, and Codestyle Rules. +* Avoid using `cargo clippy`. + +## Relevant Context + +**Important:** Before starting implementation, thoroughly review the `Readme.md` and `advanced.md` files for the `former` crate, and the `Readme.md` for `former_meta` to ensure a full understanding of the existing design, features, and intended behaviors. + +* **Primary Test Files (Tuple Variants -
