Visualize the evolution of a Git repository's languages and size

You, too, can have your repository visualized like this!

• Repose uses Tokei for LOC calculations, so you need it installed and on your path. If you're compiling Tokei by yourself, make sure JSON serialization is enabled.

• You can also alternately put tokei-tar on your PATH, and it will be used for faster and less disk-intensive computation.

• I'll assume you have uv; if you don't, create a Python 3 virtualenv or something, then pip install -e ..

• Run uv run -m repose scan -d my-repo.sqlite3 my-repo-path.
• Run uv run -m repose chart my-repo.sqlite3.
• Open chart.html. Yay!

• By default, the repo is scanned at a 1 day interval. You can pass in -r (for "resolution") to change this, e.g. -r 1w for a week, etc. This also works for chart.
• You can hang on to the database file to avoid having to rescan all of the repository's history.
• Thanks to Tokei's data format, the database contains per-file statistics too (though there is no visualizer for those yet). Maybe you can think of something to do with them?
• You can install orjson for faster JSON handling.
