Easier Lint Authoring with Semantic Search and (...)
summary
ELP (Erlang Language Platform) adds lints by matching AST shapes with SSR (structural search and replace) backed by a tree‑sitter grammar, running in VS Code/Emacs/Neovim or CLI and emitting JSON for CI. A concrete example: a diagnostic W0051 (weak warning, one of 51 existing) detects binary strings and offers an automatic fix to sigil syntax; implementation is Rust code that produces a ranged diagnostic plus a replace edit and can apply changes in place producing a diff.
