Syntax Highligting on Server Side (aka Code Format Rendering)

Author: Roman Clarkson | Posted: 14. August 2007 13:09

Here is the code being used as and Extension to render code.

The format is [code:lang;ln=on|off;alt=on|off] all of your code [code]. I am tinkering with the format because I am curious if there will be a need for other options. Like forcing a block display so that the code wraps, does not wrap, etc. the

Replace LANG in [code:lang] with the options c#, vb, js, html, xml, tsql, or msh. <--Sets language
Set LN= to on or off <-- Sets line numbers
Set ALT= to on or off <-- Sets alternating background line colors.

The system handles the rest.

By the way you need the current builds or need to add the style sheet additions at the end of the post.

[code:c#;ln=off;alt=off]
