Here's a few +tricks to checkout a merge request locally. + +#### Checkout locally by adding a git alias + +Add the following alias to your `~/.gitconfig`: + +``` +[alias] + mr = !sh -c 'git fetch $1 merge-requests/$2/head:mr-$1-$2 && git checkout mr-$1-$2' - +``` + +Now you can check out a particular merge request from any repository and any +remote. For example, to check out the merge request with ID 5 as shown in GitLab +from the `upstream` remote, do: + +``` +git mr upstream 5 +``` + +This will fetch the merge request into a local `mr-upstream-5` branch and check +it out. + +#### Checkout locally by modifying `.git/config` for a given repository + +Locate the section for your GitLab remote in the `.git/config` file. It looks +like this: + +``` +[remote "origin"] + url = https://gitlab.com/gitlab-org/gitlab-ce.git + fetch = +refs/heads/*:refs/remotes/origin/* +``` + +You can open the file with: + +``` +git config -e +``` + +Now add the following line to the above section: + +``` +fetch = +refs/merge-requests/*/head:refs/remotes/origin/merge-requests/* +``` + +In the end, it should look like this: + +``` +[remote "origin"] + url = https://gitlab.com/gitlab-org/gitlab-ce.git + fetch = +refs/heads/*:refs/remotes/origin/* + fetch = +refs/merge-requests/*/head:refs/remotes/origin/merge-requests/* +``` + +Now you can fetch all the merge requests: + +``` +git fetch origin + +... +From https://gitlab.com/gitlab-org/gitlab-ce.git + * [new ref] refs/merge-requests/1/head -> origin/merge-requests/1 + * [new ref] refs/merge-requests/2/head -> origin/merge-requests/2 +... +``` + +And to check out a particular merge request: + +``` +git checkout origin/merge-requests/1 +``` + +[protected branches]: protected_branches.md |
