How to pass '--first-parent' to Repo.iter_commits() ?

[mbanders]

The command git rev-list has a lot of options including a very useful one --first-parent: https://git-scm.com/docs/git-rev-list

Is there a way to pass '--first-parent' as an option to Repo.iter_commits() ?

As the documentation of iter_commts() suggests keyword arguments can be used to pass additional arguments to the underlying git command. Specifically, repo.iter_commits(first_parent=true) should do the job.

Passing arguments works in most of the GitPython API, here is more on how parameters are converted to CLI flags.
