====== Syntax Highlighting ======
DokuWiki includes support for code syntax highlighting as described at the [[wiki:syntax#syntax_highlighting|syntax page]].
Starting with DokuWiki release "Greebo" some additional GeShi options for syntax highlighting are supported:
* Enable line numbers
* Start line numbers at line **n**
* Highlight certain lines extra
All options are set by adding some key-value pairs to the standard ''code''-tag syntax. The following examples explain their usage.
===== Examples =====
The following code enables line numbers:
var de = function() {
return (typeof(window.de) == 'object') ? window.de : {};
}();
This is the result:
var de = function() {
return (typeof(window.de) == 'object') ? window.de : {};
}();
The next example additionally highlights one line:
var de = function() {
return (typeof(window.de) == 'object') ? window.de : {};
}();
This is the result:
var de = function() {
return (typeof(window.de) == 'object') ? window.de : {};
}();
You can also highlight multiple lines:
var de = function() {
return (typeof(window.de) == 'object') ? window.de : {};
}();
This is the result:
var de = function() {
return (typeof(window.de) == 'object') ? window.de : {};
}();
Line numbers can start at any given value:
void main () {
printf ("Hello World!");
exit 0;
}
This is the result:
void main () {
printf ("Hello World!");
exit 0;
}
