Re: compiler in php..

I had thought of that, but, if I'm doing a C-style preprocessor: #define blah It just comes back as a comment with the tokenizer. The syntax of the commands wont be PHP code anyway. And I dont necessarily want to parse all of the php code since I'm not going to be doing anything with it (well, later, I may try to add macro expansion in the php code, but not now..). Additionaly, I need also to parse and compile the same commands in a different syntax that resembles the typical html templates, ie, {variable} and <!-- BEGIN block --> and <!-- END block -->. I dont think the php tokenizer would help much here. I understand the basics behind a compiler, I was just hoping there were some tools to help with writing a compiler in PHP, even a good, fast tree class would help... (and for those curious what I'm doing, I'm trying to make a Frame Processor for PHP, as described in the book "Framing Software Reuse". I want it to run dynamicaly so you dont have to add a compile step.)
