Re: positive regex for inverted match

~~Just set the match to be exactly zero times.~~

~~print "$_" if $_ =~ /(bar){0}/;~~

- - arden.

Update: Thanks hossman++, this is proof you shouldn't attempt regexes at 3am when you're sleep-walking.

Uh, no. That will match every string, because "bar" 0 times is the empty string, and every input matches the empty string. `laptop:~> perl -le 'print "matches" if "bar" =~ /(bar){0}/;' matches laptop:~> perl -le 'print "also matches" if "barbar" =~ /(bar){0}/;' also matches laptop:~> perl -le 'print "event this matches" if "" =~ /(bar){0}/;' event this matches` [download]	[reply] [d/l]
