bug#24158: Problem in set-face-attribute for whitespace mode in terminal

Hello,

I have the following problem with Emacs *in a terminal* (emacs -nw)

This configuration *does* works (red over transparent background)

(global-whitespace-mode t)
(set-face-background 'whitespace-space nil)
(set-face-foreground 'whitespace-space "red")


This one *does not* work (the background is grey):
(global-whitespace-mode t)
(set-face-attribute 'whitespace-space nil :background nil :foreground "red")

However, it should be the same, right?

Interestingly, it works with eval-region though.
Thanks for your help!

Regards,
Kip

If it does work with eval-region, then how to reproduce the situation
where it doesn't work?

Thanks.

Sorry for the long delay.

I tried your recipe, and I couldn't reproduce the problem: both
variants worked for me the same when I put them in my ~/.emacs.

What is your Emacs version?  (I tried in the latest development
sources.)

Also, if you put in your .emacs only those settings, does it still not
work?  If it works then, you probably have something else in your
.emacs or the site-wide init files that interferes with these face
settings.

Hello Eli,

Here's the .emacs file:

I'm on debian. Here's my Emacs version:

If you use the config file as is *in a terminal*, it will display a grey
background for white spaces
But if you eval region the set-face-attribute line, the grey background
will disappear

Kip

Thanks.  But please try just these two lines:

 (global-whitespace-mode t)
 (set-face-attribute 'whitespace-space nil :background nil :foreground "red")

and nothing else.  If this works for you in Emacs 24.4 that you have,
then we can investigate which of the other customizations gets in the
way.  If just those two lines don't work, I'd ask you to try a newer
version of Emacs, maybe this was a problem that was since solved.

Just tried, it does not work. Here's a print screen of editing the .emacs
file:

1. this works:
[image: Inline image 1]

2. This does not work, at first load
[image: Inline image 2]

3. After eval region:
[image: Inline image 3]

Kip

Strange, it works for me even in Emacs 24.4.

However, I see that your default face background is dark (black or
similar), which is not the Emacs default.  How is that background get
set?  Do you have a site-lisp file or do you do it in .Xresources or
something?  It could be that the reason is in whatever makes the
background dark.

Closed as this doesn't look like an Emacs problem.
