Re: Must do regex range quantifier { } as a greedy

That's what you want?

  DB<21> say 'aaabbbb' =~ /aa(?!a)b{0,2}/; say "<$&>"
1
<aabb>

Ranges are greedy by default, i.e. if they match at all.

BUT

  DB<22> say 'aaaccccaaabbbb' =~ /aa(?!a)b{0,2}/; say "<$&>"
1
<aa>

Please elaborate...

Your elegant solution won't match the edge case of `aa`, but it's unclear to me whether that is relevant for the OP.	[reply] [d/l]

> won't match the edge case of `aa` hmm ... works for me `DB<24> say 'aa' =~ /aa(?!a)b{0,2}/; say "<$&>" 1 <aa>` [download] or did you mean something else? Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery}	[reply] [d/l] [select]

Aaah - I got tripped up by my own test harness. Yes, once I use your regular expression, it works for me as well.	[reply]
