How art-dupl Differs

art-dupl combines:

• AST-level analysis (not text/token-based) — understands Go semantics
• Suffix tree algorithm — O(n) duplicate search with O(1) transitions
• Three matching modes — semantic, exact, structural
• Generated-code filtering — auto-detects 6 generator categories
• CI baseline gating — record accepted state, gate on new clones
• Templ support — full .templ AST analysis
• 7 output formats — including SARIF for GitHub Security
• Programmatic SDK — embed in your own tools

Integration with golangci-lint

art-dupl is not currently integrated with golangci-lint. To use alongside it:

# Run golangci-lint for linting
golangci-lint run

# Run art-dupl for clone detection separately
art-dupl -t 15

Or use the pre-commit hook to run art-dupl automatically.
