Emacs and Colors and RedHat

Emacs and Colors and RedHat

[William D. Colburn (aka Schlake)]

At work we are being forced to move from Slackware to Redhat.  Aside
from the fact that backspace and delete stopped working, the biggest
problem for me is that emacs suddenly has all these colors that make it
unsuable.

I have compared lisp file and settings inside emacs from both Slackware
and Redhat, and they both seem identical.  I tried compiling a stock
emacs from the source I used to make my Slackware emacs, and it had
colors under Redhat.

Blue and some kind of purple seem to the favorite color for emacs to
use, and tragically I can't read anything in those colors.  This has
made using the help inside emacs especially painful.  I tried using
xterm-mono as my TERM, but colors still appear.

Does *anyone* know how to turn this off so that I can go back to a
readable screen with emacs?

Hi Luis,

not a pretty solution but it should resolve your problem.

Put in your .emacs
(set-face-foreground 'font-lock-builtin-face "White")
(set-face-foreground 'font-lock-comment-face "White")
(set-face-foreground 'font-lock-function-name-face "White")
(set-face-foreground 'font-lock-string-face "White")
(set-face-foreground 'font-lock-variable-name-face "White")

:)

Cheers,

Put the following into your ~/.Xresources file:
Emacs.Background: white
Emacs.Foreground: black

Uh, no, didn't help.  Any emacs with -nw still has weird colors in it.

With -nw, that's a different matter.  Then Emacs inherits its colors
from the xterm it is running in.  Unless it is overriden elsewhere.
What do you get for trying

  emacs -nw -q -no-site-file

Is this different?

How about "emacs -nw -q --no-site-file"?  Does that produce the
default colors you are used to?

Nope, they are still there.  As I said, I even tried copying over the
slackware emacs, and recompiling it myself with a prefix in /tmp to see.

I miss the good old days of emacs 18.

How about "emacs -nw -bg black -fg white"?

Oh!  Excellent!  It was backwards from what I want though.  When I set
the -bg to white, it turned some horrible gray, but I found that by
omitting the -bg it stayed white, and the -fg worked to clean up the
colors in the letters!

I still don't know what causes it to happen on RedHat, but now that I
have a fix I'm happy.

The Xresources stuff only works with X - using -nw turns off X
support. The colours you are getting when running with -nw are
probably the xterm (or whatever terminal your using to run emacs
-nw). You would have to set the xterm values in your Xresources.

Apart from X resources, you can use M-x customize-face <ret> to
customize all the faces in emacs. Note that at first, emacs will start
with the same colours, but once your .emacs file runs, it will change
to the colours you set with customize-face.

You haven't said what version of Emacs you were used to and what version
you're running now, what major mode you're using (what kind of files you're
editing), what minor modes are in effect, what operations you're performing,
or precisely what is being displayed.

`M-x crystal-ball' reports:

Try `C-u 0 M-x global-font-lock-mode' to turn Global Font Lock mode off.
Try `M-x list-faces-display' to display faces and customize their attributes.

Under Redhat I'm running Emacs 21.2.  I'm used to running Emacs 21.2.  I
don't have to be editing a file at all, just trying to use the built in
help system.  Actually, it is primarily the help system that is causing
the problems.

I already have global-font-lock-mode off.  If I turn it on even more
weird colors appear.

Yes!  Those are the weird colors that appear.  They are set to the
"default", which is what I like them set too.  On everything but redhat,
the default is what I want.  Even if I compile my own emacs, they appear
when I run it on a redhat box.

I apologize for appearing to be dense, but maybe it would help if you
were to describe what's happening in more detail.  For example, you
could start describing how you start Emacs, and then you tell us what
you need to do to see unreadable colors.

And then, maybe a screenshot would be nice.

Others have tried to exercise their crystal balls, but maybe there
was too much static from the sun this week.

My crystal ball tells me that the distribution switch included an
upgrade from Emacs < v21 to Emacs == v21, which now supports colorized
tty.  Where the OP used to have straight white on black, or vice
versa, he now has beautiful font-locked color in his xterm.  I gather
that the beautiful colors are the wrong choice for his xterm color
scheme, for instance dark blue on black.  I think the OP is asking for
the means to disable color completely on TTY, but he might be even
happier with a quick way to force reasonable color choices for his
(black background?) xterm.

Of course, he might be even happier with running Emacs in its native
windowing mode, but my crystal ball has run out of steam.

Well, Emacs has different color schemes for light and dark
background, and it might have no clue about what you set the terminal
to.

frame-background-mode's value is nil

*The brightness of the background.
Set this to the symbol `dark' if your background color is dark, `light' if
your background is light, or nil (default) if you want Emacs to
examine the brightness for you.  Don't set this variable with `setq';
this won't have the expected effect.

You can customize this variable.

Defined in `faces'.
