Re: Matching and replacing the minimum string from the tail of the regex

in reply to Matching and replacing the minimum string from the tail of the regex

I'm not sure if there is a better way, but to me the obvious approach is to accept 'start' followed by '(not start)*' followed by 'end':

my $lines = do { local $/; <DATA> };
$lines =~ s{
  ^ s \n                     # start line
  (?: ^ (?! s \n ) .* \n )*  # body excluding new start line
  ^ e\ p $                   # end line
}{}xmg;
print $lines;

Note that this does more work than the original failing substitution, so you can expect it to be slower.

I'm assuming that the start of a test is "an 's' followed by a newline", and on that assumption being a bit stricter than your original example about matching that.

Hope this helps,
