Am I asking too much of Perl regex?

;) No, is Perl regex asking too much by asking you to know what you're asking for ? *zing*

perlrequick

Luckily YAPE::Regex::Explain handles these

use YAPE::Regex::Explain; print YAPE::Regex::Explain->new( '\b\$AVG' )->explain; __END__ The regular expression: (?-imsx:\b\$AVG) matches as follows: NODE EXPLANATION ---------------------------------------------------------------------- (?-imsx: group, but do not capture (case-sensitive) (with ^ and $ matching normally) (with . not matching \n) (matching whitespace and # normally): ---------------------------------------------------------------------- \b the boundary between a word char (\w) and something that is not a word char ---------------------------------------------------------------------- \$ '$' ---------------------------------------------------------------------- AVG 'AVG' ---------------------------------------------------------------------- ) end of grouping ----------------------------------------------------------------------
use YAPE::Regex::Explain; print YAPE::Regex::Explain->new( '\w?\$AVG\b' )->explain; __END__The regular expression: (?-imsx:\w?\$AVG\b) matches as follows: NODE EXPLANATION ---------------------------------------------------------------------- (?-imsx: group, but do not capture (case-sensitive) (with ^ and $ matching normally) (with . not matching \n) (matching whitespace and # normally): ---------------------------------------------------------------------- \w? word characters (a-z, A-Z, 0-9, _) (optional (matching the most amount possible)) ---------------------------------------------------------------------- \$ '$' ---------------------------------------------------------------------- AVG 'AVG' ---------------------------------------------------------------------- \b the boundary between a word char (\w) and something that is not a word char ---------------------------------------------------------------------- ) end of grouping ----------------------------------------------------------------------
