bug#22746: 25.0.90; OS X: Visual bell hard to see

[Adrian Robert]

The visual bell on OS X used to be a large square popped up in the middle of
the screen, which was easy to see.  Now it is a very small warning icon, and I
often miss it.  Would it be possible to make the warning icon the same size as
the square was, or if the icon can only be rendered at that size, provide an
option for the old square?

The old code didn't work on El Capitan -- there were some visual artifacts
left behind afterwards.

Since I didn't have access to a machine running El Capitan, I replaced the
code with something that work on all OS versions.

It might be possible to increase the size -- however, the symbol is a
built-in image so there is a risk that an enlarged version will be
pixelated.

I'm open to other solutions to this. Unfortunately, I don't have the time
to work on it myself anymore.

Emacs mac port has the option to flash the top line and mini buffer as
visible bell, can we introduce this feature to Nextstep port?

I'd like this too, although now that the visual bell icon is bigger, it's been
working for me.

What would be the ideal visible bell? The top and bottom lines flashing
or flashing the entire window, or do people like the warning icon?

Personally I'd prefer top and bottom lines. Every better: give me a defcustom
to decide between icon, top/bottom, whole screen, or some alerting function
(which in future would allow for connecting with alert.el).

+1.  And not just for OS X.

It could also incorporate what echo-bell.el does, or similar,
as one of the option values.

Am I right in thinking that this would just require exposing the bell
functions to Emacs lisp, and then providing a simple way to set
ring-bell-function? Or have I misunderstood?

Are you asking me?  I only suggested perhaps incorporating something
like what echo-bell does, as one of the possible visual-bell behaviors
for the defcustom.

There already is an easy way to set `ring-bell-function', so I'm really
not sure what you are asking.

Sorry, I probably should have responded directly to John.

This is why I'm not sure why John's asking for a way to tie in an
alerting function. It's already there.

Sorry, I just didn't know about it. :)

So, do we keep the current behavior and rely on third-party packages
like echo-bell.el to customize the behavior?

Or, if we should chose to customize built-in the behavior, maybe a few more
settings should be considered:
 - Duration: Compared to echo-bell-mode, the default warning sign is
 shown way too long. A configurable duration would be nice.
 - Image: Maybe people also would like to specify the image shown as
 visible bell (e.g. Pikachu: https://twitter.com/ErgoEmacs/status/759546738306748416/photo/1 )

TBH, I suggest to keep the current behavior and let user to set
`ring-bell-function' if they like something different.
