Is it possible to create merge requests in pure Git from the command line?

You may use this command line tool: https://github.com/brauliobo/gitorious-merge-request

./gitorious-merge-request -e [email protected] -s 'test' -r '~brauliobo/noosfero/brauliobos-noosfero' -a easysafeinstall -b master -t 'noosfero/noosfero'

The answer given by svick is not correct. It is possible.

There's git request-pull which is part of the Git suite. Using that command line tool, you could create a pull request that could be sent per E-Mail.

Example:
your origin holds a branch master. Now you create a local bugfix branch fix, implement the bug fix and push that fix branch to origin:

git push origin fix:fix

Then, you want someone to merge the changes made in the fix branch into master. Create the pull request with

git request-pull master origin

This will create a text formatted as follows:

The following changes since commit <SHA of master>:

  <commit message of SHA of mster>

are available in the git repository at:
  <repo location> fix

<User Name> (<Number of Commits>):
      <messages of the commits>
      ...

 <changed files>
 ...
 <file statistics>

---

If the merge request shall go to somebody that cannot access your repo where you pushed your changes, there's always the opportunity of doing it with git format-patch.

After pushing your fix branch to origin (you don't even need to do that), while being on the fix branch create the patch using

git format-patch master..

This will create a patch file for each commit you did in fix since branching off master. You could bundle the generated .patch files with

tar czf fix.tgz *.patch

and then send to someone e.g. via E-Mail to review and apply.

For the sake of completeness: applying the patches could be done with git am.

There is no such thing as “merge request” in git itself. So, if this would be possible, it would require something specific to your git host.

Gitlab add this feature from v11.10. After committing your final changes, instead of push simply use:

git push -o merge_request.create

to create a merge request. More details in push docs or merge request docs.
