- For
- Developers maintaining tests across multiple languages
- Worth noticing
- Language-specific Lua profiles let contributors define semantics without rewriting the shared smell-detection rules.
Field notes
The workflow separates language parsing, Lua-based language profiles, and reusable detection rules; the page says this lets one rule implementation work across supported languages. Its sample output includes file-level findings and a summary, while JSON output is shown as an alternative. The listed stack includes Tokio for parallel processing and an optional Language Server Protocol integration for additional diagnostics and symbol information.
