blink-matching-paren jump-offscreen

blink-matching-paren jump-offscreen

[Mario Lang]

Hi.

Updating to Emacs 29, I see that my setting of

blink-matching-paren

is apparently not honored.  About 2 years ago, I came here
to let you know that at least me was really depending on
blink-matching-paren
to use a jumping point.  So the feature was, after having been rewritten
recently, reinstated.  Thanks for that.  However, next dev version, and
the feature is apparently broken again.

It is great that Emacs has a lot of ongoing development.
However, it would be even nicer if this ongoing development
would not regularily destroy old-school features long-term power users
depend on.

What is "your setting", and how is it not honored by Emacs 29?  Please
tell the details, preferably in the form of a reproducible recipe
starting from "emacs -Q", so that we could investigate and try to fix
what became broken.

As a matter of fact, we are trying very hard not to break past
behavior, and when that is for some reason unavoidable (and I'm not
saying this is the case here), provide options to get back the old
behavior.  Occasionally, we make mistakes and fail to do TRT, but
there's definitely no intentional breakage of past behavior.  Quite
the contrary.

So please bear with us and help us repair what we inadvertently broke.

TIA

Sorry, I was assuming you would be able to infer this from the subject:

My blink-matching-paren is set to 'jump-offscreen, and I expect
it to behave like it used to do before.  IOW, if I type
a matching closing paren, I want point to briefly jump to the matching
paren, and go back again.  Basically the same as if I manually typed

) M-b M-f

This is how blink-matching-paren always behaved, before
someone decided to make it "better" around Emacs 28 development phase.

I rely on point jumping around, because I basically dont see
any color changes at all.  I am using Emacs with a braille display in
emacs -nw.

It still does do that for me, if I turn off show-paren-mode (which is
now ON by default).

I don't think blink-matching-paren have changed in what it does,
except when show-paren-mode is turned ON, which serves a similar
purpose.
