Subject: zend_highlight routine
From: aidan@php.net ("Aidan Lister")

I'm rewriting the highlight_file/string methods in userland code (using the 
tokenizer) because I've found the native functions painful.

It is difficult to insert line numbering properly, and have accurate 
function referencing - most pastebins now use PEAR's Text_Highlight to 
highlight the code with a bunch of intensive preg_matches. Hopefully this 
can be updated one day (though according to the bug reports it caused 
segfaults with the current implementation), but until then I thought this 
may be useful.

I'm almost finished:

http://aidan.dotgeek.org/lib/?file=PHP_Highlight.php

My problem is the token2color method, I'm not sure which tokens are classed 
as keywords. At the moment I've just guessed as many as I could think of, 
it's a bit ugly - presuming there is an easier way to do it.

I've had a look through zend_highlight.c and found that anything with 
token.type = 0 is highlighted as a keyword, however I'm unable to track down 
where token.type is set.

Is anyone able to provide some insight?

King Regards,
