diff-mode: kill various hunks at once, something like kill-region?

diff-mode: kill various hunks at once, something like kill-region?

[Uwe Brauer]

Hi


Does somebody know about a package that would allow to kill serval hunk
in one go or even having something like kill-region in a diff buffer?


Regards

If what you mean is kill/delete several stretches
of text at once, where you provide the limits of
each such stretch, then you can do that with an
iteration.  "At once" here would refer to the
overall effect, but maybe you have something else
in mind?

If you use library zones.el then you can use
`zz-do-zones', which just does such an iteration,
applying a function to a list of zones (start +
end positions).  But for this simple an operation
you can as easily use `dolist' over such a list.

Workflow and motivation:

I use HG (but for git the workflow is very similar)

    1. I call vc-dir

    2. I select the files I want to commit

    3. I use vc-diff

    4. In the diff file I manipulate hunks

    5. I either use

       1. commit-patch, a perl script that allows to submit
          the edit diff file as patch.

       2. Or the solution implemented by Dmitry which currently dwells
          in Emacs master


Now sometimes if the diff file is huge, I might only want to commit 2
out of say 20 hunks.

So instead of killing 18 hunks, I'd like to mark the hunks I would like
to delete and somehow delete them in one go (kill-region-hunk is not
implemented)

So what you propose, would serve this purpose?

[SOLVED, sort of] (was: [External] : diff-mode: kill various hunks at once, something like kill-region?)

Well, the diff buffer in diff-mode is read-only, but that as I learned
is not essential. So toggling read-only off and using kill-region, does
the job! 

Sometimes the simplest solutions are the best. 🙃
