git-stack-cli

• ✨ Stacked diffs for git
• 🚀 Simple one-branch workflow
• 🎯 Interactively select commits for each pull request
• 💬 Group commits for focused code review
• 🌐 Use the official GitHub CLI
• ♻️ Automatically synchronize each pull request in the stack
• 💪 Work seamlessly with GitHub's interface
• 🚫 Avoid juggling mutiple branches and complex rebasing
• 📚 Preserve your detailed commit history
• ⚡ Faster, in-memory rebase via git revise

Demo

Install

[!TIP]

Install via Homebrew to ensure the official Github CLI and git revise dependencies are installed automatically

brew install magus/git-stack/git-stack

If you prefer to use npm you will need to install the official Github CLI and git revise dependencies separarely

brew install gh
brew install git-revise

npm i -g git-stack-cli

Usage

git stack             # group and sync commits in branch to Github

git stack --check     # print status only, skipping rebase and sync to Github
git stack --verbose   # print more detailed logs for debugging internals
git stack --no-verify # skip git hooks such as pre-commit and pre-push

git stack help        # print a table of all CLI arguments

Editing existing commits and pull requests

Sometimes you want to add changes to an existing commit or pull request. With git-stack this is as simple as amending the commit.

1. git add your changes to the stage
2. git stack log to find the relative commit number you want to amend
3. git stack fixup <number> to amend the specific commit with your staged changes.

git add -p
git stack log
git stack fixup 2

Running git stack afterward will update any existing pull requests with your changes.

Why?

The goal of git stack is to combine the simplicity of developing in a single branch in order to preserve your commit history while also grouping commits into pull requests for code review.

Often pushing all your commits to a single pull request is the simplest and fastest approach to development. This comes at a price, your teammates have to review larger, less related pieces of code and you will lose some of your atomic commit history if you "Squash and merge".

When you decide to break changes up into multiple diffs that depend on one another this process is commonly referred to as stacked diffs (pull requests that depend on other pull requests). This approach is popular at many major companies such as Twitter, Facebook, etc. Managing stacked diffs manually involves managing multiple local branches, jumping between them, rebasing, etc. This process gets even more complicated when you start getting feedback in code review and have to update individual branches. Managing even a few stacked diffs requires a relatively strong knowledge of git, even with tricks like --update-refs.

How is this different than x

ghstack

• git stack automatically synchronizes each pull request in your stack, as needed
• git stack does not create local branches (instead it annotates commits locally with metadata to denote groups of commits, e.g. git-stack-id: E63ytp5dj)
• ghstack requires rebasing and squashing since each commit creates a pull request, which means you lose commit history
• git stack allows developing in a single local branch and selecting groups of commits for each pull request
• git stack adds a clear comment to each pull request in the stack showing the entire stack
• git stack does not break if you land pull requests through Github directly, ghstack requires landing from the CLI interface
• git stack uses the official GitHub CLI (gh) instead of personal access tokens

Development

Ensure node --version is the same across both projects you are using to test the git-stack cli

git submodule update --init --recursive
npm i
npm run dev
npm unlink git-stack-cli
npm link

# navigate to project to test within
npm unlink git-stack-cli
npm link git-stack-cli

git stack --verbose

Build standalone executable

npm run build:standalone

Publishing

[!IMPORTANT]

You must update the version in package.json before running npm run release. DO NOT use npm version or commit the change, the release scripts handle git tags etc.

npm run release

# release individually
npm run release:npm
npm run release:github
npm run release:brew
