Checking out pull requests locally

git fetch origin pull/ID/head:BRANCHNAME

git fetch origin pull/8112/head:temp

 

How can I check out a GitHub pull request with git?

问题

I'd like to check out a previously created pull request (created via GitHub web interface). I searched and found different places where a refs/pull or refs/pull/pr

But when I add fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to the git config file and do a git fetch

What I'm doing wrong? Should GitHub create automatically the pull/xyz stuff, or do I have to configure something?

To fetch a remote PR into your local repo,

git fetch origin pull/$ID/head:$BRANCHNAME

where $ID is the pull request id and $BRANCHNAME is the name of the new branch that you want to create. Once you have created the branch, then simply

git checkout $BRANCHNAME

For instance, let's imagine you want to checkout pull request #2 from the origin main branch:

git fetch origin pull/2/head:MASTER

See the official GitHub documentation for more.

That gist does describe what happend when you do a git fetch:

Obviously, change the github url to match your project's URL. It ends up looking like this:

[remote "origin"]
    fetch = +refs/heads/*:refs/remotes/origin/*
    url = git@github.com:joyent/node.git
    fetch = +refs/pull/*/head:refs/remotes/origin/pr/*

Now fetch all the pull requests:

$ git fetch origin
From github.com:joyent/node
 * [new ref]         refs/pull/1000/head -> origin/pr/1000
 * [new ref]         refs/pull/1002/head -> origin/pr/1002
 * [new ref]         refs/pull/1004/head -> origin/pr/1004
 * [new ref]         refs/pull/1009/head -> origin/pr/1009
...

To check out a particular pull request:

$ git checkout pr/999
Branch pr/999 set up to track remote branch pr/999 from origin.
Switched to a new branch 'pr/999'

You have various scripts listed in issues 259 to automate that task.
The git-extras project proposes the command git-pr (implemented in PR 262)
