mediawiki安装实现代码高亮的插件GeSHiHighLight

1.下载新版本的GeSHi(http://qbnz.com/highlighter)

2.解压，复制geshi目录到mediawiki的扩展目录(extensions)下（建议删除contrib和docs两个目录及内容）

3.在mediawiki的扩展目录（ectensions）下，新建GeSHiHighlight.php，加入文件内容如下：

# you want to change the below two lines
require_once("geshi/geshi.php"); // i asume geshi.php is in the same directory as GeSHiHighlight.php (that is 'extensions' dir)

define("GESHI_PATH","extensions/geshi/geshi");// definition where are stored geshi language parsing files

# ok, end of editing :)

class SyntaxSettings {};

$wgSyntaxSettings = new SyntaxSettings;
$wgExtensionFunctions[] = "wfSyntaxExtension"; 

function wfSyntaxExtension() {
    global $wgParser;
    $langArray = geshi_list_languages(GESHI_PATH);
# $langArray = array("actionscript","ada","apache","asm","asp","bash",
# "caddcl","cadlisp","c","cpp","css","delphi",
# "html4strict","java","javascript","lisp", "lua",
# "nsis","oobas","pascal","perl","php-brief","php",
# "python","qbasic","sql","vb","visualfoxpro","xml");
    foreach ( $langArray as $lang ){
        if ($lang == "" || $lang == "div") continue;
        $wgParser->setHook( $lang,
        create_function( '$text', '$geshi = new GeSHi(trim($text,"\n\r"), "' ."$lang". '", GESHI_PATH);
        return $geshi->parse_code();'));
    }
} 

/**
* function: geshi_list_languages
* -------------------------
* List supported languages by reading the files in the geshi/geshi subdirectory
* (added by JeffK -- Jeff, any more contact info?) -- I haven't tested the code is is, will do that shortly. -Rogan
*
*/
function geshi_list_languages ( $path = 'geshi/' )
{
    $lang_list = array();
    if ($handle = opendir($path)) {
        while (false !== ($file = readdir($handle))) {    // Loop over the directory.
            if(is_dir($file)) continue;                    // Drop anything that is a directory, cause we want files only
            if( ".php" == substr($file, strrpos($file, "."),4)) // process only .php files
            {
            $lang_list[]= substr($file, 0, strrpos($file, "."));
            }
        }

        closedir($handle);
    }
    sort($lang_list); //sort the output, i like ordered lists in Wiki Version page :)
    return $lang_list;
}
?>

4.在mediawiki的根目录下的LocalSettings.php文件中加入

include("extensions/GeSHiHighlight.php");

该内容加在变量$wgSitename之前
