Sundgren is Swedish for "sound branch". Given a repo, a base ref and a patch (usually one that changes tests), it answers: what happened to source coverage because of this patch? It runs your coverage command on the tree before and after the patch, and reports the lines, branches, functions and test outcomes that changed.
Install
uv tool install sundgren # or: pipx install sundgren
Linux and macOS (x86_64 and arm64). The wheels hold a self-contained binary, so running it needs no Python. Windows is not supported yet.
Docs
- Examples: a Python and a Rust project, the command and the report.
- How it works
- Reference: every option, preset key, exit code and warning.
- Changelog
Development
One Rust crate (Rust 1.88+); Python is only the test harness and the docs build.
cargo test && cargo clippy --all-targets -- -D warnings
uv sync && uv run pytest # e2e and docs tests, run the built binary
To release, set the version in pyproject.toml and Cargo.toml, date its CHANGELOG.md
section, check with uv run tools/release.py check vX.Y.Z, and push the vX.Y.Z tag. The tag
publishes to PyPI and deploys the docs site.
