bug#52158: 29.0.50; Add key binding fo vc-git-stash

[Manuel Uberti via Bug reports for GNU Emacs, the Swiss army knife of text editors]

In my init.el I have this code:

(defun mu-vc-git-stash (pop-or-delete)
   "Create, pop, or delete Git stashes.
With no POP-OR-DELETE call `vc-git-stash'. With one prefix
argument call `vc-git-stash-pop'. With two prefix arguments call
`vc-git-stash-delete'."
   (interactive "P" vc-dir-mode)
   (cond ((= (prefix-numeric-value pop-or-delete) 4)
          (call-interactively #'vc-git-stash-pop))
         ((= (prefix-numeric-value pop-or-delete) 16)
          (call-interactively #'vc-git-stash-delete))
         (t (call-interactively #'vc-git-stash))))

(with-eval-after-load 'vc-dir
   (keymap-set vc-dir-mode-map "z" #'mu-vc-git-stash))

Stashing is something I do regularly, so I was missing a key binding for it in 
`vc-dir-mode'.

I am not suggesting to add something like `mu-vc-git-stash', though, that is 
just an example of me wrapping useful and related Emacs commands in order to 
make them easily available. Nonetheless, 'z' is free in `vc-dir-mode-map' right 
now and `vc-git-stash' is not bound to any key.

What do you think?

If you go up to the "Stash" line in vc-dir buffers, there's a bunch of
stash-related commands bound there.  `C' is bound to `vc-git-stash'
there, for instance.

Interesting, I didn't know about this. Although that's probably because when I 
do C-h m in vc-dir buffers I don't see key bindings related to stash-related 
commands, so I thought it was unbound.

Actually, I've now discovered that P is bound to vc-git-stash-pop-at-point when 
I move to a line that refers to a stash, so I have no need for my previous 
wrapper any more.

Thank you for pointing out the key binding. This can be closed, I guess.

I'm wondering whether we could make these commands more discoverable,
though.  If you put point there and hit `C-h b', it'll list the
commands, but not elsewhere in the buffer (since these are text property
keymaps).

Anybody got any ideas here?  Adding some text to the major mode doc
string about how there could be more commands available at certain
points in the "header" of the buffer?

Another thing I did not know, thanks.

It'd be helpful to have them documented on C-h m. That's the first I thing I hit 
in a major mode I am not familiar with.

Either that or add commands that go to the first stash and pops
etc. They'd have to unhide the stash list if it were hidden,
though (and I wouldnʼt bind the 'kill-stash' thingy).

The problem is that vc-mode is generic and stashes are very specific to
Git.  Perhaps we should have introduced a bunch of minor modes, really.
Like `vc-dir-git-mode' etc.  These might be pretty empty modes, but at
least they'd offer a convenient place to put doc strings, if nothing
else.

This wouldnʼt work anyway, since the bindings conflict with vc-dir

We could steal^Wborrow from magit, which puts all the stash commands
on the 'z' prefix. To be honest I never do much with vc mode anymore,
magit does everything I need and more, and git has taken over the
world, so Iʼm not sure we should work too hard on vc mode.

'z' is the key binding I am using for the custom function I wrote about in the 
opening mail of this ticket, and I agree the Magit does a lot of good things, 
but I have been using vc-mode every day for more than a week[1] so may I just 
say "please don't stop working on vc-mode!"?

Sure, the new vc-dir-git-mode could add a `z' keymap.

Dmitry, does adding some vc-specific minor modes to vc-dir buffers sound
OK to you?

Perhaps adding a derived major mode would be a more succinct solution?

Similar to how we have vc-git-log-edit-mode.

vc-git's addition to the new major mode would be to add a keymap with 
extra commands.

OTOH, for better user experience this will probably require duplicating 
the contents of vc-dir-mode's docstring. Or would adding a reference to 
it suffice?

Does a derived mode give us anything more than a minor mode would?  We
basically need a place to put helpful text in the doc string, as well as
binding some Git-specific commands, and that seems like a perfect fit
for a minor mode.

Only in the way of retaining more uniformity in the approach.

Perhaps minor modes are indeed good to use here. Especially if it's only 
one per backend (for this particular command).

I've now added this, and put the two relevant stash commands on the `z'
map.  Feel free to adjust, rename or move things around.

Thank you for this. May I suggest to add 'z p' bound to vc-git-stash-pop to 
vc-dir-git-mode-map?

But that command pops the stash under point, so you have to move point
to a stash line first.  So it doesn't seem very helpful to have in the
minor mode map.

It does, and thatʼs the one bound to 'P' in the stash area
keymap. 'pop' is destructive, so I think it should be bound only when
youʼre actually looking at the stash list (unlike the new 'z c' and 'z
s' bindings).

BTW, the stash area bindings are all upper case, and the new ones are
lower case. Can we make them more consistent?

Well, I could say "damn backwards compatibility" and just move your
new bindings to upper case, since they've existed for all of 2 days,
or I could boldly trample over the vc-dir map and add lower case
versions of the stash area ones. Or I could say "itʼs a prefix map,
and itʼs consistent with magit, and who uses their <shift> key these
days anyways".

Iʼm getting a strong "do nothing" feeling for the outcome here. 🙂

I'm really fine with either decision here. Not that I'm likely to use 
these bindings myself either.

Most of my efforts in the keybinding-related discussions has been spent 
on arguing against one Emacs maintainer (who worries about backward 
compatibility -- sometimes too much, IMO), and if you don't see any 
conflicts (or don't assign much importance to them), and there is a 
consensus among users -- please go ahead.

Good idea, please add it - I spend too much time every day navigating
several lines upwards to the vc-dir header before typing a key to pop a stash,
and then back after typing a key.

Whereas typing 'z p' bound to vc-git-stash-pop everywhere in the buffer
will allow to type TAB in stash name completion when only one stash
is in use, so just 'z p TAB RET' - and done.

vc-git-dir-extra-keys.

Well, by using the normal minor mode mechanism, we get better support
(via `C-h b' and `C-h m') than if we add some sort of special mechanism
to vc-dir for this.
