bug#27644: 26.0.50; [PATCH] Add binding for vc-region-history

[Kaushal Modi]

[-- Attachment #1.1: Type: text/plain, Size: 390 bytes --]

Hello,

I have been using "C-x v H" binding for vc-region-history for a year and it
has been super-convenient for me for the instances of "I wonder who made
changes to this/these line(s) and when..".

Also the "H" binding is still unused in vc-prefix-map and a good mnemonic
for "history" too.

The attached patch binds vc-region-history to "H" in vc-prefix-map.

Thanks.

Any issues getting this minor patch into 26.1?

It hasn't been reviewed yet.  I'd like to hear Dmitry's opinion on the
change, before we consider whether it's important enough to have in
Emacs 26.

Thanks.

Copying Dmitry.

I use vc-region-history so frequently that not having a C-x v .. binding
for it feels like a mistake. And luckily C-x v H is not taken by anything
else. This patch fixes that.

Hello all,

I have now attached an updated path that binds vc-region-history to C-x v h
and vc-insert-headers to C-x v H based on the discussion here[1].

The patch also reflects this change in the manual.

Let's not bind vc-insert-headers to anything. Otherwise, I'm on board.

I was pretty sure I was following the required format. I'll review the

I don't have a strong opinion.

Does everybody like the proposed key combination? As another option, 
'C-x v e' is still free (for rEgion-history).

About binding this to a key in general, or about the particular key
proposed by Kaushal?  If the former, perhaps we should ask how many
others bind this to a key, or how frequently they use this command.

Thanks.

Either. It's not a very technical decision, and I very rarely use this 
command myself.

Sounds good to me.

Re: bug#27644: 26.0.50; [PATCH] Add binding for vc-region-history

[Kaushal Modi]

[-- Attachment #1: Type: text/plain, Size: 1345 bytes --]

Hello all,

In https://debbugs.gnu.org/cgi/bugreport.cgi?bug=27644, I propose a patch
to bind the vc-region-history command to C-x v H.

* Why vc-region-history?
- I find that command very useful; especially to dig though who
specifically touched a set of lines in emacs code and when. I used it very
recently[1] to associate a strange behavior I started seeing in ggtags.el
package with an upstream change in emacs.

* Why bind to C-x v H
- That binding is an easy mnemonic; the "H" in C-x v H for
vc-region-(H)istory.
- That binding is available

So the questions to the list:
- How frequently do you guys use vc-region-history?
- If you bind it, what do you bind it to?
- Is there a reason why this patch should not be applied?

Thanks all.

Kaushal

All the time.

C-x v h

I've never found the default binding of C-x v h to be of any use.

If we do end up adding a binding, this makes a lot of sense.

vc-insert-headers only seems useful with older VCS-es, and even there, 
not particularly essential.

Not sure we can do this change this close to Emacs 26 release, though. 
That's up to the current maintainers.

It a matter of changing just the binding. It's not as if a new
functionality or change in older functionality needs to be thoroughly
tested.

Also, I made that patch proposal back in July[1]. And seeing that we still
need to get the first 26.1 pretest out, I thought it might not be too late
for this just-binding change. I hope the maintainers can ship it with emacs
26.1. If not that, at least in the master.

Well, I couldn't be happier. I also never found the C-x v h binding useful.
Thanks for the input.

Thank you.

Thank you everyone. So far the concensus is to set the binding for
vc-region-history to C-x v h.

@Eli: Are there any objections? If not, I'll update the patch for
committing.

Isn't C-x v h already `vc-insert-headers'?

Hi John,

As mentioned earlier in the thread, Stefan suggested this binding as he
never found the default binding useful[1], Dmitry corroborated that[2], I
have never found the default useful. Later Clement and Jostein also chimed
in a +1[3, 4].

So far there has been no opposition to binding C-x v h with
vc-region-history.

I am basically proposing to bind the super-useful vc-region-history to
"something" in "C-x v" map. I offered C-x v H. But based on the above
discussion C-x v h makes more sense.

I would be great to get a clear "yes" or "no" as this issue seems to have
lingered too long.

I'd put this very concisely as:

(let ((res (binding--vc-region-history--resolution)))
  (cond ((string= "yes, C-x v h" res)
         "best option")
        ((string= "yes, C-x v H" res)
         "good option")
        ((string= "no, don't bind vc-region-history" res)
         "bad option, but I'll accept")
        (t
         (error "invalid"))))

Hah, I love it. :)

I'm all for making it C-x v h, and having C-x v H insert headers. The former
is by far the more common operation, and in this case I'm willing to break
with tradition for better convenience. Please give this a good notice in the
NEWS file, so people notice.

Thank you. I have emailed the patch (re-based to emacs-26 HEAD) on the
debbugs # 27644 thread[1].

Only the rcs, cvs, sccs and svn backends support it (and svn only for
backwards compatibility with CVS), and inserting vc headers has been
recommended against for at least 15 years if not longer. I say replace
the binding.

I also suggest changing C-x v h to be something more useful. Although 
I'm a co-maintainer for RCS and still use RCS for some things, I've 
never used C-x v h with its old meaning.

That's good to hear! That adds to the consensus that vc-insert-headings is
not useful.

I have provided a patch that binds C-x v h to vc-region-history history in
the debbugs thread[1] .. just need someone to commit that.
