•Re: Problem with negative lookahead at end of string

For simplicity sake, you can list a compound "and-ed" condition as a series of null assertions:

/
  ^ # anchor so as not to try this at every spot
  (?= chars ) # stars with chars
  (?= .*? this ) # contains this
  (?! .*? that ) # does not contain that
  (?! .* whatever $ ) # does not end in whatever
/xs

update: edited to include additional whitespace for readability

Nice. "I'd walk a mile for a (Programming Perl) Camel." Had to reach for it to get through that ?!.*? regex! I'm just an old C programmer, learning more than one way to do it...
