In-line text

Interesting features

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

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

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

Defining your own set of colors

Sometimes you may be not quite satisfied with the defaut colors used in ConTeXt built-in text highlighting: 

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

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

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
