RegEx with $ anchor not Perl-compatible

[Chad Martin <chad.e.martin@…>]

If I try to match a string like "WORD1 WORD2" with boost::regex lastWordCapture("(
w+)$"); in order to capture WORD2, the regex_match fails. If I modify the regex to ".*?(
w+)$", it works fine. The following Perl code captures and prints WORD2 as expected.

$string = "WORD1 WORD2"; if ($string =~ /(\w+)$/){

print "$1\n";

}

I believe you are confusing regex_match with regex_search, which is what should have been used for the case you tried.

You're right. I was used to the fact that Perl doesn't split those two functions up, and so I didn't expect that in Boost. Now that I understand the difference, my code works fine.
