Home: Perl Programming Help: Regular Expressions: YAPE-Regex-Explain-1.01

japhy Enthusiast / Moderator Feb 5, 2001, 11:31 PM Post #1 of 2 (5002 views) YAPE-Regex-Explain-1.01 Can't Post If you're having trouble understanding a regular expression, and the documentation doesn't seem to help you, YAPE::Regex::Explain is probably the tool you've been searching for! Go to http://www.pobox.com/~japhy/YAPE/ for more information on this module. In a nutshell, you give it a regex, and it tells you, in a verbose, node-by-node outline, what the regex does.

Jasmine notified me about this module somewhere in the beginners forum. I've been trying to make a CGI interface for this module. Hope that notifying at the page bottom that I use your module is good enough... However, you might want to the following things: A. bad explain - Try it yourself: - goto [url=http://www.codingdomain.com/cgi-bin/frameset.cgi?url=perl/explainregexp.html]my YAPE::Regex::Explain interface - enter "\Q at $0 line \E\d+\." in the textarea. (without the quotes) The explainregexp.cgi uses that regexp to remove "at <file> line <x>" strings from an error message. My scripts validates the regex in a eval {m//} statement first, before your module is used. B. Inheritance Also, I've been trying to use inheritance at your explain module (to add a explainHTML() method). I wanted the result to be displayed in a more HTML way. The only sad thing is the fact that the $format variable is initialized from the explain() method. So when I copy-paste-adjust the code of the explain() method to my module, I can't get the explain() methods in the element classes working, since they require $format is initialized. Maybe adding a setFormat method is a nice feature. All other things seam to work correctly. This is still a great job. I guess this will be useful to a lot of developers.
