Question

What Perl variables are used for the positions of the start and end of last successful regex match?

Était-ce utile?

La solution

As the perlvar man-page explains:

$+[0] is the offset into the string of the end of the entire [last successful] match. This is the same value as what the pos function returns when called on the variable that was matched against.

$-[0] is the offset of the start of the last successful match.
