OT: Regexp buddy
Dark Ambient
It supposedly supports Ruby regexp and is supposed to make the use of
regular expressions a lot easier.
btw, I'm not connected to the software or company but would like to
know how it fits in with Ruby programming.

It prevents you from doing stupid little mistakes that take you hours to
find out...
you can even debug you regex and learn a lot!
ruby (and lot's of other languages / regex flavours) got some decent
support and
you can even create fancy little code snippets with it!

Does it make a good learning tool for regexp ?

There's also RegexpCoach
http://weitz.de/regex-coach/
Which is free for private or non-commercial use. I think this is a
good tool for learning as you can investigate closely how a regexp
goes about matching text. If RegexpBuddy has similar functionality
then it's probably equally suited to support learning. And then of
course there is http://www.oreilly.com/catalog/regex/ which is a great
book.
Kind regards

powerful and comes with many useful features that appear to be robust. Their
library of regex is quite excellent that you can get a lot of help very
quickly. It can generate Ruby/Perl/Python/Java code to support regular
expressions. However, it has problems dealing with language specific regular
expressions and breaks down when an expression gets a bit complicated. Also,
when I contacted the support, I never hear from them at all! Bottom line: if
you like the features it supports and find them useful, buy it. I think it
provides a great way to learn and experiment. If you're well versed in
regular expressions, it may not help you much. If you're looking for
support, I hope that you have a lot of time and patience!

Section A-4 of the above document tells you the differences between
the new regexp engine and the current one. You could do a mental diff
