Development

This repository uses mise to pin Rust.

mise install
mise run ci        # fmt-check + clippy -D warnings + test, exactly what CI runs
mise run test
mise run install   # build and install into ~/.cargo/bin

CI runs the suite on Linux and macOS, checks the declared MSRV, and smoke tests the release binary against a throwaway project — the tests here drive real git, real process groups, and real ports, so they are integration tests by nature. On a pull request macOS runs a subset, the tests that exercise what differs there; main runs all of it. .config/nextest.toml lists what the subset skips, and cargo nextest run --profile macos-pr runs it locally.

Workspace layout

• crates/newgit-core holds the domain model: branch instances, tracker definitions and their histories, the compose/split engine that turns tracker histories into one workspace history and back, resource definitions and lifecycle hooks, metadata storage, real-directory materialization, checkpoints and undo, export, cleanup, and the remote client.
• crates/newgit is the CLI, published as the newgit crate.
• remote/ is the hosted remote: a Cloudflare Worker with Durable Objects over Artifacts repos, deployed at https://newgit.dev.
• .newgit/ is created by newgit init. Committed: config.toml, trackers/, resources/, scripts/. Gitignored local state: branches/, checkpoints/, logs/, state/, installs/, and local/ — which holds trackers.git, every tracker's history (bare repo).
