We are working on integrating GitLab (enterprise edition) in our tooling, but one thing that is still on our wishlist is to create a merge request in GitLab via a command li
In our build script we just pop up the browser with the correct URL and let the developer write his comments in the form hit save to create the merge request. You get this url with the correct parameters by creating a merge request manually and copying the url of the form.
#!/bin/bash
set -e
set -o pipefail
BRANCH=${2}
....
git push -f origin-gitlab $BRANCH
open "https://gitlab.com/**username**/**project-name**/merge_requests/new?merge_request%5Bsource_branch%5D=$BRANCH&merge_request%5Bsource_project_id%5D=99999&merge_request%5Btarget_branch%5D=master&merge_request%5Btarget_project_id%5D=99999"
It's not natively supported, but it's not hard to throw together. The gitlab API has support for opening MR: https://github.com/gitlabhq/gitlabhq/blob/master/doc/api/merge_requests.md#create-mr
As of GitLab 11.10, if you're using git 2.10 or newer, you can automatically create a merge request from the command line like this:
git push -o merge_request.create
