This project aims for speed, precision, and extensibility. + +### Adding a New Library via patterns + +1. Edit `patterns.toml` and add a new `[[library]]` entry. +2. Use anchored regexes for `include`/`import`/`namespace`/`apis`. +3. Prefer import/include anchors; use API patterns only as secondary evidence. +4. Run `cargo test` to validate regex and stripper behavior. + +### Adding a New Language or Custom Detector + +1. Create a new crate under `crates/detector-/`. +2. Implement the `Detector` trait from `scanner-core`. +3. Provide `prefilter()` substrings and extensions for fast filtering. +4. Use comment stripping utilities to avoid matches in comments/strings. + +### Performance Guidelines + +- Stream files and avoid unnecessary allocations. +- Use `rayon` for parallelism; keep per-file work independent. +- Prefer `aho-corasick` for prefilter substring matching. +- Short-circuit after sufficient evidence unless `--exhaustive` (future work). + +### Testing + +- Add unit tests for any new stripper rules. +- Provide fixtures under `fixtures//positive` and `fixtures//negative`. +- Add integration tests in `tests/` to cover the new patterns. + diff --git a/Cargo.lock b/Cargo.lock new

languages - Add support for Swift (.swift), Objective-C (.m, .mm, .M), and Kotlin (.kt, .kts) - Implement glob-based file filtering to only process source files - Update language detection to handle new file extensions - Add --patterns CLI argument for specifying patterns file path - Update README with new language support and performance optimizations - Optimize file discovery by pre-filtering with glob patterns Performance improvements: - Only processes relevant source files, skipping docs/images/binaries - Significant speedup on large repositories with many non-source files - Maintains
