[RFE] Add patch method to pygit2.Patch returning patch diff string for an individual changed file

[jnareb]

The Diff class / type has patch method, which returns patch diff string, of all changes as whole. You can iterate over Diff and get Patch for each changed file. However Patch class does not have patch method, and there is currently no way to get patch diff string for an individual file.

GitPython has in its equivalent of per-file diff information, namely git.diff.Diff (equivalent of pygit2.Patch) method called diff, which returns patch diff string... but without diff headers.

P.S. Could we have some labels to easily distinguish bug reports from feature requests, and so on, please?

I am also interested in this feature. It shouldn't be too difficult at all given the availability of git_patch_to_buf and the Diff.patch blueprint

Thanks!

P.S. I have added a few labels.

Does the #741 also adds Patch.patch to the pygit2 documentation?

[jdavid]

No. Added it now in the latest commit. Thanks.
