## Project history and usage

spr is a Rust command-line tool for using a stacked-diff workflow with GitHub pull requests. It treats individual commits, rather than long-lived review branches, as the unit of code review.

### Project history

The project was created in 2022 and documents its workflow as a GitHub-oriented version of ideas familiar to users of Phabricator's arc tool. Its documentation frames the motivation as avoiding a branch-per-review workflow while still using GitHub pull requests.

### Adoption history

spr is distributed as source and binaries through GitHub releases and is packaged for Homebrew and nixpkgs. Its repository metadata and badges also point to Rust and crates.io distribution, placing it in the small but visible ecosystem of stacked-diff CLIs for GitHub users.

### How it is used

Typical use starts with `spr init` inside a GitHub-backed repository, which writes spr settings into the repository's Git config and guides GitHub authorization. Users then run `spr diff` to create or update pull requests from commits and `spr land` to merge approved work.

### Why package nerds care

Package-manager users care about spr because it brings a formerly review-system-specific workflow, stacked commit review, into a standalone GitHub CLI. It is useful in environments where developers want the local simplicity of rebasing a single mainline branch but still need GitHub pull requests for review and merge.

### Timeline

- 2022: GitHub repository created and v1.0.0 published.
- 2025: v1.3.7 published on GitHub releases.

### Related projects

- spr's documentation explicitly compares the workflow to Phabricator and its `arc` command-line tool. It also belongs to the broader family of stacked-diff tools used around GitHub pull requests.
