gitcharts
A repository with some cool charts that tell us about the history of a git repo.
With charts like this you get an idea of how quickly code is rewritten in a repo. You can explore the GitHub pages link or the marimo notebook to learn more.
Notebook usage
You can download git_archaeology.py locally to run it, but you can also run it in molab without downloading anything. The marimo notebook contains all dependencies so can just run marimo edit to edit the notebook locally:
uvx marimo edit git_archaeology.py
CLI Usage
You can also run git_archaeology.py as a command-line script:
uv run git_archaeology.py --repo https://github.com/marimo-team/marimo --samples 50
Arguments:
--repo (required) — Repository URL (HTTPS)--samples (optional, default: 100) — Number of commits to sample--file-extensions (optional, default: .py,.js,.ts,.java,.c,.cpp,.h,.go,.rs,.rb,.md) — Comma-separated file extensions to analyze--version-source (optional, default: git tags) — Version source: none, git tags, or pypi
After generating charts, run make build to update the repository index:
make build
This runs generate_repos_list.py to create charts/repos.json from the available chart files.
Viewing Charts Locally
Due to browser security restrictions, you cannot open index.html directly from the filesystem. Instead, start a local HTTP server:
uv run python -m http.server
Then open http://localhost:8000 in your browser.
More ambitous?
This project was intended for Python projects but the idea is catching on and some folks have started porting this idea to Rust for better performance. If you're keen to explore that, check out https://github.com/czechbol/strata.
