# PR: Major improvements to WTIsMyCode ## Summary Comprehensive refactoring and feature additions to WTIsMyCode โ€” the Python architecture documentation generator. This PR improves code quality, adds new features, and significantly enhances the development experience. **Stats:** 24 files changed, ~3900 insertions, ~1400 deletions, 50 tests ## Changes ### ๐Ÿ—๏ธ Architecture - **Decomposed monolithic `main.rs`** into `commands/` module structure (generate, init, check, stats) - **Added workspace `Cargo.toml`** for unified builds across both crates - **New `cycle_detector` module** with DFS-based dependency cycle detection ### ๐Ÿ Python Analyzer - **Full AST traversal** โ€” properly walks all statement types (if/for/while/try/with/match) - **Function signatures** โ€” extracts parameter names, types, defaults, return types - **Method detection** โ€” distinguishes methods from standalone functions via `self`/`cls` parameter - **Docstring extraction** โ€” parses first line of docstrings for symbol documentation - **Module path computation** โ€” correctly computes module IDs from `src_roots` config ### โœจ New Features - **`stats` command** โ€” project statistics with colored output and progress bar - **Config validation** โ€” validates project root, language, scan paths, cache age, file size formats - **Cycle detection** โ€” finds circular dependencies in module graph, shown in critical points section - **`--dry-run` flag** โ€” preview what would be generated without writing files - **Dynamic project data** โ€” uses config project name and current date instead of hardcoded values - **Real usage examples** โ€” generates Python import/call examples from analyzed symbols - **Skip-unchanged optimization** โ€” writer skips files that haven't changed ### ๐Ÿงน Code Quality - **Zero `unwrap()` calls** in non-test code โ€” proper error handling throughout - **Zero clippy warnings** โ€” all lints resolved - **50 tests** โ€” unit tests for config validation, cycle detection, caching, integration detection, error handling, and full pipeline integration tests ### ๐Ÿ“š Documentation - **README.md** โ€” badges, full command reference, configuration table, architecture overview - **CHANGELOG.md** โ€” complete changelog for this branch ## Testing ```bash cargo test # 50 tests, all passing cargo clippy # 0 warnings cargo build # clean build ``` ## Breaking Changes None. All existing functionality preserved.
