git_diff(ref = NULL, repo = ".")

git_diff_patch(ref = NULL, repo = ".")



a reference such as "HEAD", or a commit id, or NULL to the diff the working directory against the repository index.


The path to the git repository. If the directory is not a repository, parent directories are considered (see git_find). To disable this search, provide the filepath protected with I(). When using this parameter, always explicitly call by name (i.e. repo = ) because future versions of gert may have additional parameters.
