How can I highlight a non php file?

Will_W

I'm doing a lot of java work and I would like to use php's syntax highlighting since It worked so great with php. I've been able to do it ok but php requires me to do the <? at the beginning of every java file and I don't want to have to do this to every java file (lots) Anyone know how I could do this in java?

Below is the code sample I have been using for years with php

function highlight($filename) {
    if ((substr($filename, -5) == '.java')) {
        ob_start();
        show_source($filename);
        $buffer = ob_get_contents();
        ob_end_clean();

} else {
    $argv = '-q -p - -E --language=html --color '.escapeshellcmd($filename);
    $buffer = array();

    exec("enscript $argv", $buffer);

    $buffer = join("\n", $buffer);
$buffer = eregi_replace('<?', "", $buffer);
    $buffer = eregi_replace('^.*<PRE>',  '<pre>',  $buffer);
    $buffer = eregi_replace('</PRE>.*$', '</pre>', $buffer);
}

// Making it XHTML compatible.
$buffer = str_replace("&lt;?","",$buffer);
$buffer = eregi_replace('<FONT COLOR="([^"]*)">',
    '<span style="color:\1">', $buffer);
$buffer = eregi_replace('</FONT>', '</style>', $buffer);

return $buffer;
}
?>

Ok guys if you need to view any type of file and want that file highlighted with php highlighting try this little example out. be very careful and make sure to put validation in it so only use it for testing ok.

<html>
<head>
<title>View Source Code of Any File</title>
</head>
<body>
 <h1>View File with PHP Highlighting</h1>
    <!--//We will start by creating the form-->
    <form name="form1" method="GET" action='
    	<?php
    		#Just telling the form to submit it's data to this same script..
    		#We use PHP's $_SERVER["PHP_SELF"] buit-in variable.
    		#This is very useful as you can rename this script and it will still work..
    		echo $_SERVER["PHP_SELF"];
    	?>
    '>
    	<input type="file" name="selected_file">
    	<input type="submit" value="View">
    </form>
    <hr>
    <?php
    #if we have selected a file, then proceed..
    if(!$_GET['selected_file'] == "")
    	{
    		#get the full path from URL string
    		$userfile = $_GET['selected_file'];
    		#print the full path
    		echo "<b>Full Path:</b> " . "/" . $userfile;

		#Split the URL string into an array at every occurence
		#of \\ eg.(G:\\devel\\myscript.php gives: "G:","devel","myscript.php")
		#We can then isolate the last value in the Array which we can assume will be the filename
		#The last value of an array is determined by using the end() function.
		$myArray = split('\\\\', $userfile);
		$selected_file_name = end($myArray);
		#print the filename
		echo "<br /><b>filename:</b> " . $selected_file_name . "<hr>";

		#read the contents of the file and split it into an array using file()
		#(You could try "$newStr = file_get_contents($selected_file_name)", depending on your PHP version, instead of the 			#following 2 lines)
		$strFile = file($selected_file_name);
		$newStr = join("<?",$strFile);

		#HTML comment "start copy here"
		echo "\n\n\n<!--//######################################\n";
		echo "START COPY HERE\n";
		echo "#################################################-->\n\n\n";

		echo "<div style='background:whitesmoke;'>";

		#PHP's built-in syntax highlighting function is used..
		//highlight_string($newStr);

		echo "</div>";

		#HTML comment "END copy here"
		echo "\n\n\n<!--//######################################\n";
		echo "END COPY\n";
		echo "#################################################-->\n\n\n";

		#Or you could use
	//$newStr = str_replace("<?","",$newStr);
		$blah = highlight_string($newStr,1);
	$blah = str_replace("&lt;?","",$blah);
	echo $blah;
		echo "<p><hr><i>End Of File</i></p>";
	}
else
	{
		#Display this message if no file is selected..
		echo "Please select a file.";
	}
?>
</body>
</html>

This is a slimmer version of the above code plus a little validation


<?php
  highlight('SMTP.java');

  function highlight($file) {

if(!$file == "") {
   if ((substr($file, -5) == '.java')) {

      $myArray = split('\\\\', $file);
      $selected_file_name = end($myArray);

      $strFile = file($selected_file_name);
      $newStr = join("<?",$strFile);

      $blah = highlight_string($newStr,1);
      $blah = str_replace("&lt;?","",$blah);

      echo $blah;
   } else {
     echo "The File is not a java file";
   }
} else {
echo "Please select a file.";
}
  }
?>
