Go Geshi Function

Why the Go GeSHi function?

• Automatic creation of .src files, and addition of the link to the box for easier code downloads.
• The .src file automatically detects when you put up a new version and creates the new file then.
• Makes use a bit easier, instead of typing all the OOP components and including the file many times, this is preset to use PHP (though you can change that), and is very simple to use. Works great on sites where all the code is in one language.
• Word-wraps the text that extends beyond your desired width (700px by default) for all pre-tags
• Makes the links to PHP (or other) function documentation open in a new tab, and default to no-follow (to preserve page rank).

Configuring

• $language - The programming language the source is in (for example: PHP) There's a list on the GeSHi homepage of supported languages.
• $path_to_geshi_languages - If you copied the GeSHi folder into your sites directory, there's another GeSHi folder inside of that where all the language packs are at. Adjust if needed.
• $generate_downloads - TRUE to have auto-generation of downloads, and the link shown... FALSE to disable.
• $width_in_px - how wide you want the code area to be.

One last note...

How to use the code

<?PHP
go_geshi("BaSe64EnCoDiNgHeRe==");
?>

The Code

if (!function_exists(go_geshi))
	{
	function go_geshi($source)
		{
		//Configuration
		$language = "PHP";
		$path_to_geshi_languages = "geshi/geshi";
		$generate_downloads = TRUE;
		$width_in_px = 700;
 
		$source = base64_decode($source);
		if ($generate_downloads) {
			if (!file_exists("src-" . md5($source) . ".src")) {
				$file = fopen("src-" . md5($source) . ".src","w");
				fwrite($file, $source);
				fclose($file);
				}
			}
		echo "<style type='text/css'>.geshi-rl-box>pre{white-space:pre-wrap;white-space:-moz-pre-wrap!important;white-space:-pre-wrap;white-space:-o-pre-wrap;word-wrap:break-word;width:{$width_in_px}px}</style>";
		require_once('geshi/geshi.php');
		$geshi = new GeSHi($source, $language, $path_to_geshi_languages);
		$geshi->enable_line_numbers(GESHI_FANCY_LINE_NUMBERS,2);
		$geshi->set_link_target("_blank\" rel=\"nofollow");
		echo "<div class='centeredbox geshi-rl-box'>";
		if ($generate_downloads) echo "<a href='src-" . md5($source) . ".src'>Download Original</a><br />";
		echo $geshi->parse_code() . "</div>";
		}
