gitpython equivalent of git-apply

Question

Is there a way to apply a patch (in the form of a diff file) to a repo using only the gitpython library?

In other words, is there a gitpython equivalent of the git-apply command?

Answer 1

Solution is to do

r = Repo('path-to-repo')
r.git.execute(['git','apply','patch.diff'])

I had tried this before but I had omitted the 'git' at the beginning of the argument list, which gave an error about the command not existing.

• Nishant: Is there no API in gitpython to do this directly? I am asking this because, most of the time we have a string which contains diff. In that case we will have to first write the diff to a file - then run r.git.execute and then clean up the file.
• chuck1: as far as i know there is nothing in the API. are you familiar with tempfile, I think that will make your scenario fairly painless

Answer 2

You can use git directly, like this:

 repo = git.Repo('repository_path') 
 repo.git.apply(['-3', 'patch-file'])

this will perform the git command:

git apply -3 patch-file
