Subject: 25.0.50; Setting ‘blink-matching-delay’
 has no effect
Date: Tue, 18 Aug 2015 18:55:47 +0600

Setting ‘blink-matching-delay’ has no effect:

  (setq blink-matching-delay 0.5) ; 1 second delay is used
  (setq blink-matching-delay 3)   ; still 1 second delay is used

I read source code and saw that ‘sit-for’ is used to implement
delay. I've tested it and it works with floating point arguments as well
as any integer arguments on my system.

Works fine here. I see an appropriate delay as set above.

Try reproducing it starting with 'emacs -Q'.

Doesn't work for me even with ‘emacs -Q’. Are you sure you are seeing
0.5 second delay?

Here is how I test it:

1. Start Emacs with ‘-Q’ flag.

2. Evaluate:

  (setq blink-matching-delay 0.5)

3. Re-check its value and description: ‘C-h v blink-matching-delay RET’.

4. Open some file with long data within parentheses, scroll down so you
   don't see opening parenthesis.

5. Delete closing parenthesis and type it manually.

6. Period of time for which opening parenthesis is shown is always 1
   second. You can set it to 5 seconds, it will be 1 second no matter
   what.

So this is about the case when you don't see it. You haven't mentioned 
this before.

The behavior you're describing was a recent regression, and it was fixed 
in b892438d7 (yesterday). I've touched up on that fix now, but either 
way should work for you.

I've pulled/rebuilded Emacs. Now it doesn't just to opening parenthesis
at all.

It does, as long as the opening paren is visible in the current window. 
That has always been its behavior.

If the opening paren is not visible, its line is merely displayed in the 
echo area.

Strange. I tried in combination with:

  (setq blink-matching-paren 'jump)

Nothing seem to produce that effect, I really liked it. I can't believe
this handy behavior was not intentional and now it's lost.

If that behavior that I liked so much was sort of bug, consider adding
it as a feature.

All right, you can try (setq blink-matching-paren 'jump-offscreen) now.

I'm sorry, still doesn't work for me :-(

I'm testing it the same way described above, but evaluating

  (setq blink-matching-paren 'jump-offscreen)

after setting of ‘blink-matching-delay’.

Yes, of course. I'm sure I'm using Emacs with your recent changes,
because ‘C-h v blink-matching-paren RET’ results in:

  blink-matching-paren is a variable defined in ‘simple.el’.
  Its value is jump-offscreen
  Original value was t
  
  Documentation:
  Non-nil means show matching open-paren when close-paren is inserted.
  If t, highlight the paren.  If ‘jump’, briefly move cursor to its
  position.  If ‘jump-offscreen’, move cursor there even if the
  position is off screen.  With any other non-nil value, the
  off-screen position of the opening paren will be shown in the
  echo area.
  
  You can customize this variable.

You should try 'make bootstrap' anyway.

And what doesn't work for you exactly? The jump offscreen, or 
customizing its delay value?

Nevermind, I just rechecked it with ‘-Q’ flag. It works! Everything
works: delay time and jumping. Thank you. I need to investigate why it
doesn't work with my configuration…

Now I know that it doesn't work when ‘show-paren-mode’ is enabled. I
would like to use this blinking feature together with
‘show-paren-mode’. Is it possible?

Sorry, it's too much for me to get into right now.

But this should probably be implemented in show-paren-mode. Please file 
a separate bug with this feature request.

And please clarify: the way it works now, are you going to use 
`jump-offscreen'? If not, I'm going to revert that commit.

Please don't revert it! This is very useful feature (make sure it is
mentioned in the docs).

“As is”, this is already very good thing that works flawlessly until you
activate ‘show-paren-mode’. I will send separate bug report, I hope this
will work fine in combination with that mode.

Thanks.

It's mentioned.

My point is, the relevant show-paren-mode behavior will most likely be 
predicated on a different variable.

So that latest change (that I would revert) won't help it in the least.
