Re^2: Counting frequency of expressions in a string

/\b(\d{2})-(\d{2})-(\d{4})\sPerl\sParty/gs

You don't have any dots in this regexp, so the /s is useless. You might feel like I'm nitpicking, and I am: I wouldn't mind its presence in actual production code.

But this is a site for ~~earning~~ learning, you shouldn't set a bad example, too many people are cargo culting code (especially regular expressions) from this site already, so I think we should releave the code we post here from any voodoo as much as possible, so people will actually begin to understand the code they're copying.

Thank you.

For earning? I have not earned much here. Maybe you mean learning? ;-) holli, /regexed monk/	[reply] [d/l]

You are of course quite right. The hidden story is that there was a `.*?` in there following a `\G`. I realised the anchor and wild card were redundant and removed them, but forgot to remove the /s. So the further lesson is: look, then look again. And each time you make a change, look twice more. That time I only looked once more. :) Perl is Huffman encoded by design.	[reply] [d/l] [select]
