Hi All,
You can see from the following screenshot that my `git ls-files -m` output
is only `book-urls.txt`. I mean it is the only modified file.
*[image: Screenshot-2020-10-16-04:40:30.png]*
Now on top of `Completing tree file` (which list all the files) I want to
place `Completing modified files`.
How can I do that?
*Thanks and Best Regards,Ahmad Ismail*

Hi All,
I think it is not showing the screenshot or something. So, I asked the
question in stackoverflow.
https://stackoverflow.com/questions/64381142/append-the-output-of-a-command-as-suggestion-to-existing-competion
I think I have to use:
_git-diff 2>/dev/null
functions[_git-diff-orig]=$functions[_git-diff]
_git-diff() {
_git-diff-orig "$@"
...
}
To extend the _git-diff. However, I am not understanding what to write
there so that it shows *Completing Modified Files *which I expect to be the
output of git ls-files -m
Please help me out here.
*Thanks and Best Regards,Ahmad Ismail*

It looks like you've removed the stack overflow question already so
I'm somewhat guessing at what your issue is. Mostly, you need to move
your own code up before calling _git-diff-orig. The tag-ordering styles
can only work when there is a single tag loop in which completions are
added.
In this case, it's probably easier to tweak the original _git-diff
function than to modify it from a wrapper. And using git diff HEAD or
git diff @ to get both staged and unstaged changes is a common enough
case to warrant being special-cased. So any thoughts on the following
patch for _git. Ideally it ought to be possible to correctly handle any
arbitrary base branch name but we have existing functions for taking
care of files modified relative to the HEAD.
Admittedly, __git_changed_files itself could be improved but that's a
separate issue.

I was thinking there should be some way to implement this with a
zstyle by changing the program invoked by _call_program for the
"files" style, but I didn't have time to work out the incantation for
doing that in the nested subcommand context.

I have asked this question on reddit afterwards.
https://www.reddit.com/r/zsh/comments/jcju5h/extend_git_completion_function/
I got a solution from there. However, I am always looking for betterment.
*Thanks and Best Regards,Ahmad Ismail*

Finally had a chance to poke at this a bit more ...

In your post there, you said:

So very close.
zstyle ':completion::complete:git-diff*:argument-rest:tree-files'
command 'git ls-files -m'
One question is why ^Xh (list-tags) shows the "files" tag for that
context but not the "tree-files" tag. If you invoke completion
immediately after "git diff " (instead of after "git diff HEAD ") then
the context is "changed-in-working-tree-files" and THAT gets shown
correctly by ^Xh.

The screenshot made it through both times.
Furthermore, you referred to the screenshot in the body, so if it
_hadn't_ gone through, someone would have pointed that out.
In any case, copy-pasting the terminal contents as text (as opposed to
image) is preferable when possible, as it's easier to read, quote,
grep, etc..
