256 colors in ansi-term buffers

256 colors in ansi-term buffers

[Christopher Grubert]

Is there any way to get 256 color support in ansi-term?  By that I mean 
256 colors in an ansi-term buffer with emacs running under X, not 256 
colors for emacs -nw when running in an ansi terminal (which seems to be 
the more popular question).

Looking at the definition of eterm-color it only advertises 8 colors, 
and the code for term.el seems consistent with that, having only an 8 
entry color vector that can be remapped.  In my application I need as 
close to a real terminal as possible so eshell isn't an alternative.  
Any suggestions?
Thanks,
Chris.

I guess you'll need to add the feature to one of the terminal emulators
(either term.el or nterm.el).
IOW, patches welcome,

After thinking about it a little more I realized that I generally don't 
use more than 10 colors in my shell...just a very specific 10 colors.  
So the vector remap actually is pretty usable with only a few things 
collapsed together.  As time allows I will look at adding the full 
support.  At first glance that seems straightforward enough, although 
I'm probably underestimating it.  I haven't looked at nterm.el yet.  
I'll do that next.
