NAME

function::ngroups - Number of subexpressions in the last match.  

SYNOPSIS

    ngroups:long()
 

ARGUMENTS

None  

DESCRIPTION

returns the number of subexpressions from the last successful use of the =~ regex matching operator.

Note that this number includes subexpressions which are present in the regex but did not match any string; for example, given the regex "a|(b)", the subexpressions will count the group for (b) regardless of whether it matched a string or not. Throws an error if the last use of =~ was a failed match.
