How to disable font-lock-mode in minibuffer?

How to disable font-lock-mode in minibuffer?

[Alexandre Oberlin]

Hi all,

I am currently using GNU Emacs 24.2.1 (i686-pc-cygwin). I'll never thank  
Cygwin enough for making Windows usable when you have no way out.

I currently have an accessibility problem with the font-lock-mode. I only  
have basic colors in Cygwin, and blue on black and red on black are quite  
difficult for me to read. I know how to toggle font-lock-mode in normal  
buffers by just running "font-lock-mode", but not in the minibuffer. I  
tried to investigate but no avail and I'm in a rush for work.

Any hint?

Alexandre

Yes, don't mess with emacs, adjust your terminal programs rendering
of red and blue so that they are readable.

Every terminal program I've ever seen gives you some way to do
that, and sooner or later, you'll need the underlying problem fixed.

Most likely that's because doesn't know your background is dark.
If you tell him, he'll use different colors.
E.g. Customize frame-background-mode.

Customize the face minibuffer-prompt to have the colors you can see
well.

I prefer to use "M-x list-faces-display" for it visual verbosity and ability
to search by C-s (and edit face by RET).

Also I recommend to use Cygwin Mintty terminal emulator (run Emacs in it).

That take you 256-colour instead of 8!

Hello Oleksandr,

Thanks for your answer.

I do use mintty 1.1.2
Command line :
C:\cw\bin\mintty.exe -i c:\cw\bin\emacs.ico -e c:\cw\bin\bash.exe
I seem to have only 8 colors however.

Exactly what I wanted!
I changed minibuffer-prompt foreground to cyan on black instead of blue on  
black.

Cheers,

Alexandre

Hi Stefan,

> E.g. Customize frame-background-mode.
Fantastic ! That's the quickest way indeed.
I had already changed "minibuffer-prompt" from blue to cyan in  
"list-faces-display".
I then "customize-option frame-background-mode" to "dark", which  
automatically changed e.g. the "link" entry from blue to underlined cyan.  
Red on black however was not changed and must be done manually, but it is  
more readable than blue on black.

Thanks a lot,

Alexandre

If you have trouble with the default colors (even once
frame-background-mode is set properly), please M-x report-emacs-bug
so we can fix them.

Hi Stefan,

Only marginal items have slightly difficult to read faces. tool-bar is  
black on black but maybe this is not relevant.

I have just upgraded from 24.2.1 to 24.3.1 without adjusting anything. I  
still seem to have 8 colors only but the red on black looks brighter. Am I  
dreaming ?

Yes.

If you are running in a terminal, the terminal program sets the colors.
There is no way Emacs can adjust those colors.

I think you are on Windows?  If you have bash (Cygwin) installed,
you should be able to run this:

#!/bin/bash
  function colorred     {  echo -e '\033[31m'; }
  function colorgreen   {  echo -e '\033[32m'; }
  function coloryellow  {  echo -e '\033[33m'; }
  function colorblue    {  echo -e '\033[34m'; }
  function colormagenta {  echo -e '\033[35m'; }
  function colorcyan    {  echo -e '\033[36m'; }
  function colorwhite   {  echo -e '\033[37m'; }
  function ulon         {  echo -e '\033[4m';  }
  function uloff        {  echo -e '\033[24m'; }
  function blinkon      {  echo -e '\033[5m';  }
  function blinkoff     {  echo -e '\033[25m'; }
  function boldon       {  echo -e '\033[1m';  }
  function boldoff      {  echo -e '\033[22m'; }
  
tput reset
tput clear
ul="`ulon`Underlined.`uloff`"
bo=`boldon`Bold.`boldoff`
bl=`blinkon`Blink.`blinkoff`

echo "Demo to show all the xterm colors"
echo ""
echo     "`colorred`Red     - not my favorite.		$ul $bo $bl"
echo    "`colorblue`Blue    - can be too dark.		$ul $bo $bl"
echo  "`coloryellow`Yellow  - The color of a chicken.	$ul $bo $bl"
echo   "`colorwhite`White   - Screen background not white.	$ul $bo $bl"
echo   "`colorgreen`Green   - With envy.			$ul $bo $bl"
echo    "`colorcyan`Cyan    - a light blue.			$ul $bo $bl"
echo "`colormagenta`Magenta - a light red.			$ul $bo $bl"
echo ""
colorwhite
echo "And now in reverse image:"
tput smso
echo ""
echo     "`colorred`Red     - not my favorite.		$ul $bo $bl"
echo    "`colorblue`Blue    - can be too dark.		$ul $bo $bl"
echo  "`coloryellow`Yellow  - The color of a chicken.	$ul $bo $bl"
echo   "`colorwhite`White   - Screen background not white.	$ul $bo $bl"
echo   "`colorgreen`Green   - With envy.			$ul $bo $bl"
echo    "`colorcyan`Cyan    - a light blue.			$ul $bo $bl"
echo "`colormagenta`Magenta - a light red.			$ul $bo $bl"
echo ""
tput rmso


I used this to make sure all 8 colors were readable on my chosen
background.  If any of them aren't use the terminal program to adjust.

You can convince Emacs not to use Red and Blue, but I think you really
want your terminal to produce readable red and blue.

With a little investigation you should be able to find a 256 color
terminal program but I'd still want to make sure I had a readable red
and blue.

From http://mintty.googlecode.com/svn-history/r1065/trunk/docs/mintty.1.html

 TERM (Term=xterm)
 	The TERM variable setting at mintty startup. Choices available from the
 	dropdown list are xterm, xterm-256color, xterm-vt220, vt220, and vt100. 

 The xterm-256color setting enables 256-color mode in some applications, but
 may not be recognised at all by others, which is why plain xterm is the
 default.

Next thing is to debug your environment.

Official page http://code.google.com/p/mintty/ also state 256-color support.
