Great! That does it. Thanks. :) I realized my error on the anchors after sending... but didn't think of the * on the grouping.
On the & operator... are you saying that it would operate basically as expected... allowing sets of rules and'ed rather than or's with the | ? --- Phil -----Original Message----- From: Moritz Lenz [mailto:mor...@faui2k3.org] Sent: August 10, 2010 2:09 PM To: Beauchamp, Philippe (6009210) Cc: perl6-langu...@perl.org Subject: Re: regex and Hi, philippe.beauch...@bell.ca wrote: > rule TOP > { > ^ > [ > & <alpha>* > & <!abc> > ] > $ > } The & syntax is specced, but it's not yet implemented in Rakudo. But note that <!abc> is a zero-width assertion, so your example regex matches at the start of a string, if it does not begin with 'abc'. Since you anchor it to the end of string too, it can only ever match the empty string. You can achieve the same with just ^$. If you want to match an alphabetic string which does not include 'abc' anywhere, you can write this as ^ [ <!abc> <alpha> ]* $ Cheers, Moritz
