Git Rebase Break
Demonstrates how to use a breakpoint in your rebase workflow for inspection/debugging purposes.
# Hello and welcome to the Alchemists Screencasts! # Today, we'll look at Git Rebase Break. # The ability to *break* in the middle of a rebase was added in Git 2.20.0. # I think of *break* as a exploratory/debugging tool. # For instance, here's the history of our documentation feature branch: gl documentation...master # 💡 See the *Git Log Pretty* screencast to learn more about the `gl` alias. # Let's put a *break* after the first commit by using interactive rebase: git rebase --interactive
# Notice Git Rebase stopped after the first commit. # Adding "b" (i.e. "break") after the first commit made this possible. # To confirm, here are the details: git show # Notice there is no body to the commit. # That was careless of us so we might as well correct this behavior: git commit --amend
git show # There, much better. # Granted, we could have used Git Rebase Edit for this. # 💡 See the *Git Rebase Edit* screencast for details. # In this case, we were exploring and saw a chance to improve documentation. # Before continuing with the rebase, let's say we forgot to add a license: vi LICENSE.adoc
git add LICENSE.adoc git commit
# This technique is similar to the *Git Rebase Pick* screencast. # Except, in this case, we *added* rather than pick an existing commit. # At this point we could run tests, check the state of the project, etc. # There is a lot you can do when breaking in the middle of your history. # For the purposes of this tutorial, we'll continue with the rebase: git rebase --continue # With the rebase complete, let's check our history one last time: gl documentation...master # The only visible change is the addition of the license commit. # With Git Rebase Break, we were able to: # 1. Inspect and edit the commit before the break. # 2. Add a new commit. # 3. Potentially run tests, etc. at the point in time of the break. # Break is another tool in your Git Rebase Workflow. 🎉 # Enjoy! # https://alchemists.io # ☿ 🜔 🜍 🜂 🜃 🜁 🜄
