Find Dead Code addon.deadcode(addon="MyAddon")
Find Stale Docs docs.stale(addon="MyAddon")
Filter by Confidence addon.deadcode(addon="MyAddon", include_suspicious=false)

Capabilities

  1. Dead Code Detection — Find unused functions, orphaned files, dead exports
  2. Stale Docs Detection — Find broken links, outdated refs, version drift
  3. Confidence Levels — Definite (100%), Likely (90%+), Suspicious (70%+)

Detection Categories

Dead Code (addon.deadcode)

Category Description
unused_function Functions defined but never called
orphaned_file Lua files not in TOC
dead_export Exported values never used
unused_library Libraries in Libs/ never used
stale_event Event handlers for unregistered events
commented_code Large blocks of commented-out code

Stale Docs (docs.stale)

Category Description
dead_link Internal links to non-existent files
dead_reference Mentions of functions/files that don't exist
version_drift Old version numbers in documentation
relative_staleness Docs not updated in many commits

Workflow

Quick Cleanup

  1. Run addon.deadcode with include_suspicious=false for high-confidence issues only
  2. Remove identified dead code
  3. Run docs.stale to find documentation issues
  4. Fix broken links and update outdated references

Deep Cleanup

  1. Run addon.deadcode with all confidence levels
  2. Manually verify suspicious findings before removal
  3. Run docs.stale with all techniques
  4. Update documentation to match current code

Confidence Interpretation

Level Meaning Action
Definite 100% certain (e.g., file not in TOC) Safe to remove
Likely 90%+ certain (e.g., function never called) Review briefly, usually safe
Suspicious 70%+ certain (e.g., dynamic code patterns) Manual verification required

Best Practices

  1. Start with definite issues — These are safe to fix immediately
  2. Check dynamic patterns_G, rawget, loadstring may hide usage
  3. Preserve intentional dead code — Mark with -- KEEP: comment if needed
  4. Update docs after code changes — Run docs.stale after refactoring
