Plugin provides syntax highlighting for about 116 programming languages via Geshi.


Just select all your source code in the editor and use editor button (preferred method) or surround your code directly in WYSIWYG editor with a [codesyntax] [/codesyntax] tag like this

[codesyntax lang="php"]

//Replacing tags
$find [] = '/<br\s*\\?>/i';
$replace [] = "\r\n";
$content = preg_replace($find, $replace, $content);


[filesyntax filename="test.phps" lang="php"]

The tag in the last example should be enabled in settings. See it's description below also.

and you will get wonderful geshi formatting. Format all your source code with Preformatted style to preserve spaces.

If you need to change settings of already formatted block - select it all and press GUI editor button again. Plugin will recognize all settings you used.

Plugin recognizes several popular geshi options to render highlighting:


The relative filename of the file inside a folder, allowed for [filesyntax] tag to take the source for highlighting from. Works only in [filesyntax] tag
