Ripgrep Pattern Indexing Skill

Last-resort indexing using language-aware regex patterns. Works on any language — if rg is installed, codemunch works.

Built-in patterns per language

Run the appropriate pattern for each detected language:

# --- TypeScript / JavaScript ---
rg --json --pcre2 \
  "^(export\s+)?(default\s+)?(async\s+)?function\s+(\w+)|^\s{0,2}(async\s+)?(\w+)\s*[=:]\s*(async\s+)?\(|^(export\s+)?(abstract\s+)?class\s+(\w+)|^(export\s+)?interface\s+(\w+)|^(export\s+)?type\s+(\w+)\s*=" \
  --type ts --type js \
  --glob "!node_modules" --glob "!dist" --glob "!.next" \
  2>/dev/null
