Unusual Characters in Interactive Console

Unusual Characters in Interactive Console

[Colin Campbell-McPherson]

Hi there,

I'm trying to use irb, the interactive ruby console within emacs. When  
I execute a command the output is not rendering correctly.
I'm on OS X Leopard and have tried running emacs in Terminal, iTerm  
and Aquamacs, all with the same results. I haven't found much on the  
net aside from suggestions to change font, which hasn't worked for me.

Example:

------------------------------
irb(main):004:0> 1+1
1+1
^[[0;36m2^[[0;0m
irb(main):005:0> nil
nil
^[[0;32mnil^[[0;0m
------------------------------

should be:

------------------------------
 >> 1+1
=> 2
 >> nil
=> nil
------------------------------

Any help would be much appreciated.

Try `ansi-color-for-comint-mode-on'.

^[[0;32m and ^[[0;36m and ^[[0;0m are ANSI Escape Sequences that  
control particular aspects of the terminal (the first two set  
foreground colours, green and cyan, the latter resets to normal). In  
GNU Emacs' ANSI *terminal* emulation (M-x term RET) these sequences  
are transformed into colours.

Could be your application just needs to run some hook with: ansi- 
color-for-comint-mode-on. RTFM. (I'm only using shell command  
interpreters ...)


BTW, the characters are very usual. ^[ is a control character, and  
it's equal to ESC.
