Migrated from this thread on the devel mailing list:

https://yhetil.org/emacs-devel/86ikwiumza.fsf@gnu.org/T/#t


On Emacs 29.4, with emacs -Q

Turn on electric-pair-mode

(electric-pair-mode +1)

Then press "C-2 ("

Expected result:

Either (()) or ()()

Actual result:

(()


I noticed the unexpected behavior when attempting to surround some text
with multiple braces in order to create Anki flashcards.

More or less, I wanted to go from "foo" to "{{foo}}", and I thought
perhaps that with the whole word selected, pressing "C-2 {" would DTRT.

In general, I'm not sure whether "{}{}" or "{{}}"is more useful or
expected, but I suspect both are better than "{{}".

Thank you!

Joseph

Making it produce "{}{}" is relatively easy: we just need to call the
post-self-insert-hook for each of the ARG inserted characters.  OTOH,
to produce "{{}}" we'd probably need to rewrite the
electric-pair-mode's hook function, but I have no idea how to rewrite
it to do that.

Stefan, any suggestions?

I'm no Stefan, but I took a quick stab at it.  The following diff
teaches electric-pair-mode about numeric prefix arguments:

Thanks, but isn't it cleaner if we simply call the hook from cmds.c
the same number of times as we insert a character?

Interesting, it might work for electric-pair-mode, though I suspect that
not all functions that people put on post-self-insert-hook are prepared
to be invoked repeatedly following a single self-insert-command.

It isn't a single self-insert-command, since it inserts N characters.
So it is natural to expect the hook to be invoked those same N times.
I think.  Let's hear what Stefan thinks (and anyone else who has an
opinion or some case other than electric-pair-mode).

Hi João,

Do you have a good idea of how to make

   C-M-SPC C-2 {

wrap the selected word within two braces?


        Stefan

I think the requested behavior makes a lot of sense, but I lost touch
with the way elec-pair works and interacts with other electric modes, so
I'm not sure how to make it work without breaking other things.

In case you missed it, the patch I shared upthread might give you
some ideas.  It implements the requested behavior, safely, I think.
So I would just ask Joseph to try it out for a while and see if it
works as expected and if any other issues crop up :)


Cheers,

Eshel

I missed that, indeed, sorry.  Then maybe we should just push it to
`master` (with appropriate regression test(s)).

No great ideas no. Does it even work in the non-wrapping case? The intended
result is as if the command was run twice, no? So maybe try somehow that
the whole thing is run twice/thrice/etc...

That's what I suggested, but the result is "{}{}{}{}...", which is not
what was requested.  IOW, what is being requested is NOT what happens
when running this command N times, it should be a special handling of
the numerical argument.

Thanks for this patch!  I am testing it in my daily config.  So far so good, and I'll report back after a few weeks of usage.

Warmly,

If the preconditions are that a word is selected before each command,
I don't see how that can be.  At the very least it would be {word}{}{}{}
or something like that.  But if you arrange for word to stay selected and
point before it, I don't see why {{{{word}}}} can't be achieved.  Doesn't
have to be word at all, could be an arbitrary sexp, IIRC. Anyway,
that's all I have.

For me `C-u 2 (` results in `(()`.

I suggested a change which would yield ()().  Without the change, you
shouldn't expect getting anything useful, because the hook is called
just once, not ARG times.

I have been running this patch for over a month with no issue.  I vote
to merge it!

Nice!  How about also adding a test like the attached patch?

Looks good :)

I've now pushed my patch to master as a7192fd7b73 followed by your test

Eshel
