Function get_diff

utils/tests_fetcher.py:235–274

Get the diff between a base commit and one or several commits. Args: repo (`git.Repo`): A git repository (for instance the Transformers repo). base_commit (`str`): The commit reference of where to compare for the diff. This is the current commit, not

(repo: Repo, base_commit: str, commits: List[str])

    Get the diff between a base commit and one or several commits.

    Args:
        repo (`git.Repo`):
            A git repository (for instance the Transformers repo).
        base_commit (`str`):
            The commit reference of where to compare for the diff. This is the current commit, not the branching point!
        commits (`List[str]`):
            The list of commits with which to compare the repo at `base_commit` (so the branching point).

    Returns:
        `List[str]`: The list of Python files with a diff (files added, renamed or deleted are always returned, files
        modified are returned if the diff in the file is not only in docstrings or comments, see
        `diff_is_docstring_only`).
