1. 从这篇博客里寻找所需要的语言：http://www.undermyhat.org/blog/2009/09/list-of-brushes-syntaxhighligher/；
2. 下载对应的shBrushXXX.js脚本，比如我下载的是shBrushLua.js，它看起来像这样：
SyntaxHighlighter.brushes.Lua = function()
{
var keywords = 'break do end else elseif function if local nil not or repeat return and then until while this';
var funcs = 'math//.//w+ string//.//w+ os//.//w+ debug//.//w+ io//.//w+ error fopen dofile coroutine//.//w+ arg getmetatable ipairs loadfile loadlib loadstring longjmp print rawget rawset seek setmetatable assert tonumber tostring';
this.regexList = [
{ regex: new RegExp('--//[//[[//s//S]*//]//]--', 'gm'), css: 'comments' },
{ regex: new RegExp('--[^//[]{2}.*$', 'gm'), css: 'comments' }, // one line comments
{ regex: SyntaxHighlighter.regexLib.doubleQuotedString, css: 'string' }, // strings
{ regex: SyntaxHighlighter.regexLib.singleQuotedString, css: 'string' }, // strings
{ regex: new RegExp(this.getKeywords(keywords), 'gm'), css: 'keyword' }, // keyword
{ regex: new RegExp(this.getKeywords(funcs), 'gm'), css: 'func' }, // functions
];
}
SyntaxHighlighter.brushes.Lua.prototype = new SyntaxHighlighter.Highlighter();
SyntaxHighlighter.brushes.Lua.aliases = ['lua'];
3. 使用FTP工具登陆到WordPress空间，进入到wp-content/plugins目录，新建一个目录，取一个有意义的名字，比如syntaxhighlighter-lua；
4. 将shBrushLua.js上传到新创建的目录；
5. 在该目录创建一个另一个shBrushLua.php文件，添加如下内容：
<?php
/*
Plugin Name: SyntaxHighlighter Evolved: Lua
Description: Adds support for the Lua language to the SyntaxHighlighter Evolved plugin.
Author: Benny
Version: 1.0.0
*/
// SyntaxHighlighter Evolved doesn't do anything until early in the "init" hook, so best to wait until after that
add_action( 'init', 'syntaxhighlighter_lua_regscript' );
// Tell SyntaxHighlighter Evolved about this new language/brush
add_filter( 'syntaxhighlighter_brushes', 'syntaxhighlighter_lua_addlang' );
// Register the brush file with WordPress
function syntaxhighlighter_lua_regscript() {
wp_register_script( 'syntaxhighlighter-brush-lua', plugins_url( 'shBrushLua.js', __FILE__ ), array('syntaxhighlighter-core'), '1.1.1' );
}
// Filter SyntaxHighlighter Evolved's language array
function syntaxhighlighter_lua_addlang( $brushes ) {
$brushes['lua'] = 'lua';
return $brushes;
}
?>
6. 文件都准备完了，OK，进入到WordPress后台管理的Plugins下，应该能看到新添加的一项syntaxhighlighter-lua，激活它。
Done! It should work now!
其实新添加的js和php文件也可以放到SyntaxHighlighter插件本身的目录下，但是让它独立成插件的好处是，当SyntaxHighlighter升级时，你的个人配置不会因为覆盖而丢失。
