bug#28194: text-scale-adjust should show current accumulated scale factor

[積丹尼 Dan Jacobson]

C-x C-= runs the command text-scale-adjust.

It should give some feedback, in the minibuffer,
about the current accumulated scale factor etc.
E.g., the user repeats the command using '=', but nothing on the screen
changes until each fifth '='. In the meantime a running tally of the
current accumulated scale factor could be shown in the minibuffer so the
user knows the command is indeed doing something.

Also when the fonts get bigger (e.g., every fifth '=') have a message
saying what new font has been used.

Dunno if this responds to your request, but the mode line shows
(in the minor-mode lighter area) +1, +2, +3, or -1, -2, -3, when
you scale up or down.

Yes I see (Fundamental +2) etc. using a vanilla emacs,
but none of that when used with my

In that case, it's pilot error. ;-)  You are (apparently)
shooting yourself in the foot.  Don't do that. ;-)

I think it is more likely an emacs bug, that something I set in my
http://jidanni.org/comp/configuration/.emacs
wipes out the functionality.

Could you please provide a minimal recipe for how to reproduce this,
starting from "emacs -Q"?

OK I just did dired /tmp and saw the number in the modeline. Closing.

I can reproduce this bug.  Running either "emacs -Q" or without "-Q"
after loading all customizations from init file it works correctly:

1. C-x C-=
2. there is "+1" in the mode-line
3. and evaluation results:

text-scale-mode
=> t

text-scale-mode-lighter
=> "+1"

(assq 'text-scale-mode minor-mode-alist)
=> (text-scale-mode (" " text-scale-mode-lighter))

But after several hours of active Emacs session
this feature breaks and doesn't work anymore even in new buffers:

4. C-x b new-buffer RET
5. C-x C-=
6. there is NO "+1" in the mode-line
7. and evaluation results:

text-scale-mode
=> t

text-scale-mode-lighter
=> "+1"

(assq 'text-scale-mode minor-mode-alist)
=> nil

Since this feature is so unreliable, maybe we should duplicate
the scale factor information in two places: in the mode-line
and in the message in the echo area.

Stefan, after you pushed your patch that supports changing font size
using mouse wheel, now would it make sense to do also what web browsers do
- on pressing C-+ they momentarily display information about new percentage
in a small window.  In Emacs this information could be added to the message
in the echo area, e.g. replace

  (message "Use +,-,0 for further adjustment")

with

  (message "%s Use +,-,0 for further adjustment" text-scale-mode-lighter)

This can't be reproduced anymore, so I suppose it's fixed.
