in reply to Regular expressions are:

Both a blessing and a curse --

I'm used to using regex in Perl, or other apps using PCRE, but I have to do work in IDL ... and they have what they claim to be regex support, but it lacks:

  • Non-greedy quantifiers
  • lookahead / lookbehind assertions
  • all of the zero-width assertions other than $ and ^
  • \w, \d, \s, etc.
  • non-capturing parenthesis

So ... anyway, not all regex are created equal -- Perl regex good ... IDL regex is a steaming pile.
