Here is a TextMate Command to convert JavaScript Source to syntax highlighted HTML. It does work with every language supported by enscript. Just change -Ejavascript to -Eyourlanguage. Below is the source as well as an example. (I used the php extensions for enscript) I have a list of all supported languages in the long version of this article!

#!/usr/bin/env php
<?
if ($fp=fopen("php://stdin","r")) {
    $text="";
    while (!feof($fp)) {
        $text.= fread($fp,4096);
    }
    fclose($fp);

    $command = '/usr/bin/enscript -q -Ejavascript -p - -Whtml --color=emacs';

    $descriptorspec = array(
       0 => array("pipe", "r"),  // stdin is a pipe that the child will read from
     1 => array("pipe", "w"),  // stdout is a pipe that the child will write to
     2 => array("file", "/dev/null", "a") // stderr is a file to write to
  );

    $process = proc_open($command, $descriptorspec, $pipes);

    fwrite($pipes[0], $text);
    fclose($pipes[0]);

    $result="";
    while (!feof($pipes[1])) {
        $result.= fread($pipes[1],4096);
    }
    fclose($pipes[1]);

    proc_close($process);

    $res = preg_match ('/<PRE>(.+)<\/PRE>/s',$result, $hits);

    $html=$hits[1];

    $clean = preg_replace ('/<font color="([^"]*)">/i','<span style="color:$1;">', $html);
    $clean = preg_replace ('/<b>/i','<span style="font-weight:bold">', $clean);

    $clean = preg_replace ('/<i>/i','<span style="font-style:italic;">', $clean);

    $clean = preg_replace ('/<\/[^>]*>/i','</span>', $clean);

    echo '<pre>'.$clean.'</pre>';
}
?>
