Would it be bad style or a bad idea to extend CREATE-REGEX-DISPATCHER (html.lisp) to hold the result of CL-PPCRE:SCAN in variables you then DECLARE as SPECIAL so that the called handler function can access the match information?

Something like *MATCH-START*, *MATCH-END*, *REG-STARTS*, and *REG-ENDS* just visible for the handler.

I'm not sure if it's bad style but I wouldn't like it. Why would you need it? The handler has access to the URL anyway.

It was the first time I used CREATE-REGEX-DISPATCHER and I had to parse the URL in the handler with the same regex. It was just an idea. But I like CL-PPCRE:SCAN-TO-STRINGS more and it's clearer this way, without the specials. I've done some projects which used mod_rewrite. Typical rewrite rules matched and parsed a URL giving the registers as parameters to the "real" address. Maybe that's the reason for my first impression using CREATE-REGEX-DISPATCHER. Regards, Stefan
