How can i set create_patch=true, and meanwhile get change_type in Diff

[SongXueZhi]

I find that when i use commit1.diff(commit2,create_patch = true), chang_type of Diff is aways none. if create_patch = False, i kown that i can get chang_type of Diff , but I can get hunk text.

Can i get Diff text ,and meanWhile get chang_type of Diff?

+1 For getting change_type also set on diff item when create_patch=True.

@SongXueZhi Approach depends on your intention for further processing, but you can certainly retrieve the change type info even from a Diff generated with create_patch=True:

def get_change_type_of_diff_item(diff_item):
    if diff_item.new_file:
        change_type = 'Added'
    elif diff_item.deleted_file:
        change_type = 'Deleted'
    elif diff_item.renamed_file:
        change_type = 'Renamed'
    elif diff_item.copied_file:
        change_type = 'Copied'
    else:
        change_type = 'Modified'
    return change_type

Usage Example:

repo = git.Repo('/path/to/repository')
diff_index = repo.head.commit.diff(None, create_patch=True)
for diff in diff_index:
    print(f"{get_change_type_of_diff_item(diff)}: {diff.a_path if diff.a_path else diff.b_path}")
```

You're welcome! I ultimately chose to use pygit2, as it seems more flexible and better suited to my needs.
