git-tl makes it easy to create and manage stacked PRs on GitHub. It wraps plain git commands and uses the GitHub CLI to query the GitHub API. The goal is for git-tl to do exactly what I need it to do in my everyday work, not to be super configurable or general.

Just put git-tl in your PATH. Then you can run git tl ls, git tl sync, etc. This is not actually very pleasant to type, so you might want to configure some aliases of your choice using git config --global --edit. Here are my aliases:

[alias]
	ls = tl ls
	bc = tl new-branch
	del = tl delete-branch
	up = tl up
	down = tl down
	sync = tl sync
	ss = tl push

You'll also have to separately install the GitHub CLI and run gh auth login to authorize it with your GitHub account.

You can run git-tl --help to see an up-to-date list of subcommands and git-tl <subcommand> --help to see the options for a particular subcommand. At time of writing, these are the available subcommands:

• ls: View the branches, how they are stacked, whether their corresponding PRs are up to date, the status of the PRs, and the URLs of the PRs.

• new-branch: Create a new branch, either above or below the current branch.

• delete-branch: Delete a branch and fix up the stack.

• up: Check out the current branch's child.

• down: Check out the current branch's parent.

• sync: Fetch root branches, then rebase all other branches on their parents.

• push: Push the current branch and its ancestors to GitHub, possibly creating new PRs.

Each branch's parent is just its upstream, so you can reparent a branch manually with git branch --set-upstream-to new-parent my-branch.
