Verbatim text

Displayed text

\starttyping, \typebuffer

In-line text

\startTEX ... \stopTEX only works when typesetting the whole paragraph. If you need to type only a command or two as in-line text, you can use the following Taco's macro (hopefully this will land in the core once in the future):

\def\typeTEX
  {\bgroup
   \def\processinlineverbatim##1%
     {\processingverbatimtrue
      \localcatcodestrue
      \def\endofverbatimcommand{\TEXendofcommand##1}%
      \bgroup
      \aftergroup\endofverbatimcommand
      \futurelet\next\doprocessinlineverbatim}%
   \initializetyping{TEX}%
   \startverbatimcolor
   \processinlineverbatim\egroup }

Now you can say:

\typeTEX+\typeTEX{\typeTEX is a wonderful macro}+, isn't it?

Interesting features

Unlike LaTeX's verbatim environment, ConTeXt's typing environments have quite a range of built-in options for formatting the verbatim text.

Embedded formatting commands

The option=commands setting allows the usage of ConTeXt commands inside verbatim text, as in this example:

\definetyping[C][option=commands]
\startC
#include <stdio.h>
int main(){
	return 0;
	/BTEX{\em unreachedCode;}/ETEX
}
\stopC

Tabbing

The tab character normally corresponds to one character, as can be seen above. That value can be adjusted, using the following code (available in the 2005.06.01 version and later):

\definetyping[C][tab=3]
% for older ConTeXt versions: \chardef\spacespertab=3
\startC
int func(int a){
	if(a > 4)
		return 0;
	else
		return 10;
}
\stopC

Syntax highlighting in color

\setupcolors[state=start]
\setuptyping[option=color]

\starttext
\startXML
... your XML code ...
\stopXML
\stoptext

Defining your own set of colors

Sometimes you may be not quite satisfied with the default colors used in the built-in syntax highlighting. Taco posted this solution in the discussion on the mailing list:

\setupcolors[state=start]
\setuptyping[option=color]

% define the colors to fit your document style
\definecolor[MYcolorone]  [r=.8,g=.5,b=.5]
\definecolor[MYcolortwo]  [r=.8,g=.5,b=.2]
\definecolor[MYcolorthree][r=.8,g=.5,b=.8]
\definecolor[MYcolorfour] [r=.8,g=.2,b=.5]

% define a palete using these four colors
\definepalet[MYcolors]
  [prettyone=MYcolorone,
   prettytwo=MYcolortwo,
   prettythree=MYcolorthree,
   prettyfour=MYcolorfour]

% XML code will be typeset with the palette you just defined
\definepalet[XMLcolorpretty] [MYcolors] % the name is magic !

\starttext
\startXML
... your XML code ...
\stopXML
\stoptext

This results in:
