Support excluding files/directories in the method Commit.diff

[dclong]

The method Commit.diff supports a paths parameter to limit diff to specified paths. However, it is more convenient sometimes to exclude files/directories. And since this feature is supported by the git command, it makes to support excluding files/directories in the method Commit.diff.

Did you try to use **kwargs which will be passed to the git diff command directly? Invocations would look like repo.head.commit.diff(diff_filter='a').

If I want to explicitly exclude one file/folder from the git diff, I can get this via the CLI using git diff <SHA> ':(exclude)path/to/exclude' as suggested in https://stackoverflow.com/a/39943727.

How can I achieve this with git.diff since the exclude in not a named parameter. Hence I don't know what to specify for the **kwargs

Currently there is no support for using **kwargs for unnamed git flags, unfortunately excluding the suggested use case.
It's certainly possible to allow settings unnamed git flags through **kwargs with a set of special names, maybe like git_arg_01="value".

Thanks for your answer. It shomehow pointed me into the right direction. It just works via *args. So git.diff(<SHA>, ":(exclude)path/to/exclude") did it.
