git-show does not work for initial commits

Open Hritik14 opened this issue 2 years ago • 2 comments

docs at https://www.pygit2.org/recipes/git-show.html suggest to diff against parent to get diff show contents. For initial commits, there are not parents, thus raising IndexError

If the commit has no parents, diff its tree against an empty tree.

if not commit.parents:
    diff = commit.tree.diff_to_tree(swap=True)

@jorio It will be helpful to have this in the documentation as well. Could you please add ?
