[PATCH] completion: support amend and reword in git commit fixup option

Bob van der Linden via GitGitGadget· Oct 15, 2022, 19:54 UTC · lore

From: Bob van der Linden <bobvanderlinden@gmail.com>

The option `git commit --fixup=` has the ability to create amend and reword commits, by specifying `--fixup=amend:REF` and `--fixup=reword:REF`.

This patch allows completion of amend: and reword: prefixes when a user has already typed the --fixup= option.

In addition, this patch fixes completion of refs that can be filled in after the amend: and reword: prefixes. Previously `amend:` and `reword:` were considered part of the ref to complete, which always resulted in 0 potential completions.

    completion: support amend and reword in git commit fixup option
    
    I'd like to use git commit --fixup= more in my day-to-day work. However,
    it dawned on me that the options --fixup=amend: and --fixup=reword: were
    not supported by bash completion.
    
    I attempted to solve this by first adding amend: and reword: to the
    completions of --fixup=. In addition, I made sure that --fixup=amend:ref
    does not consider amend: to be part of the reference, thus allowing
    completion of references when --fixup=amend: and --fixup=reword: are
    used.
    
    The patch also includes completion tests for --fixup=, --fixup=amend:
    and --fixup=reword:.
