art-dupl

What art-dupl is

art-dupl is an open-source tool for finding code clones in Go repositories. It analyzes Go and .templ files and offers semantic, exact and structural matching modes. Generated code is excluded by default, with filters covering sources such as sqlc, templ, protobuf, mockgen and stringer, along with generic generated files. Results can be produced as text, rich text, HTML, JSON, Simple JSON, SARIF or plumbing output. For CI, art-dupl can record a baseline and check later scans to flag newly introduced clones; the repository also includes GitHub Actions and pre-commit templates. SARIF reports can be uploaded to GitHub Advanced Security or CodeQL. A Go SDK provides a detector interface and streaming results. The CLI supports parallel parsing and incremental analysis with AST caching, and its quick start sets a default scan threshold of five statements. The project is MIT licensed and is hosted under the LarsArtmann account.
