Grit

Grit is a from-scratch reimplementation of Git in idiomatic Rust. The goal is to match Git's behavior closely enough that the upstream test suite (under git/t/) can be ported and run against this tool.

This implementation is being written entirely by AI coding agents. The AGENT.md instructions and a snapshot of the Git source code were provided, and autonomous agents (first Cursor, then OpenClaw orchestrating Claude Code) implement commands, port tests, and validate against the upstream Git test suite.

Crates

Crate	Description
grit-cli	The grit binary — a drop-in CLI reimplementation of git with 140+ commands
grit-lib	Core library: object model, diff engine, index, refs, revision walking, merge, config, and more

Runnable library examples (repos, object database, index, rev-list, cherry-pick, and more) are documented in grit-lib/examples/.

Progress

See the project progress dashboard (generated from data/test-files.csv via scripts/run-tests.sh). The same numbers drive the static SVG above and the homepage progress card: run python3 scripts/generate-dashboard-from-test-files.py (or any full harness run that regenerates the dashboards) to refresh docs/test-progress.svg and docs/index.html.
