I like to do github code reviews, by checking out the code locally in my IDE.
If someone forks a github repo and submits a pull request, is there a way for me to checkout their code without cloning their public forked repo?
my-repo - I usually just git checkout branch
my-repo-forked - Here I need to git clone my-repo-forked and then git checkout branch
You may add the forked repository as a second remote to your local repo:
cd my-repo
git remote add forked-version [fork-url-here]
git fetch forked-version
git checkout [branch-name-here]
This way, you only have one local git for both your original repository and the fork.
More information about remotes can be found in the Pro Git Book: 2.5 - Git Basics - Working with Remotes.
