I am having trouble getting the whole enscript to work on my site, half the time it doesn’t even highlight the code correctly. :/

David, you can just enscript -q -p OUTPUTFILE –language=html –color INPUTFILE

This seems cool. And I was searching for this capability in ViewCVS. Incidentally, http://www.horde.org has Chora CVS viewer, which highlights php syntax. But I am using ViewCVS.

Now, how does ViewCVS call your script? Do you have doco on that hack?

“Now, how does ViewCVS call your script? Do you have doco on that hack?”

ViewCVS does not call this code. This is merely an example of how to perform syntax highlighting of several languages with PHP.

BTW: I am using a similar setup to highlight my code snippets on my site (http://www.designcurve.net/snippets/).

Just what I was looking for. I just couldn’t put together all the pieces myself. I too discovered enscript in connection with ViewCVS.

Doesn’t this work if php safe mode is enabled?

The regexp that turns font tags into spans is broken. You close with instead of with .

Neither do you need to use two regexps – of which the second should be an str_replace … but you can do it all with a single regexp. I’ve tried a couple of times to post my version of that bit but the form keeps eating the patterns – presuming thinking they’re HTML. I’ll try again with > and < instead of plain > and < …

$pattern = ‘/.*?<\/FONT>/’;
$buffer = preg_replace ($pattern, ‘\2?<\/span>’, $buffer);

Nice, it works. Go the preview!! :)

Ahem … it also ate some of my post … what I was trying to say earlier was that:
‘You close with instead of ’

.. I guess you have something that eats HTML tags on your site? Maybe it would make more sense to just go:

$post = str_replace (‘<’, ‘<’, $post);
$post = str_replace (‘>’, ‘>’, $post);

Just fyi, there’s a color-code / syntax-highlighting text editor for Windows called ConTEXT — although it’s pretty simple (just goes through the syntax and encapsulates words with font-color tags), it features exporting to static HTML, which may be more preferable than always calling a server-intensive dynamic script.

Just my two cents (^_^)
