  • $/ Regex (Score:2, Interesting)

    This is a hard problem. Consider backtracking (stuff it back in a buffer) and greediness (how much do you read?). The trivial cases are pretty easy, but they rapidly get complex.

    • Re:$/ Regex (Score:2, Informative)

      There have been several threads about this on p5p, and I agree with what you say. However, I think that it may be possible to make it work reasonably for non-greedy regexps, and my hunch is that most of the time non-greedy regexps would be the correct way to express most people would want for a line ending.

      Here's the middle of one p5p thread on $/ regexp [develooper.com] If people are searching, I think that some of the other threads have had qr// in the subject. (Mmm. I'm linking to a message by me. Blantant self-promotio

          <damian> Perl 6 will have multidimensional arrays and vectorizable functions and operations.

          • All programs should be expressible as combinations of Ook. Ook? and Ook!

          <damian> Perl 5 already has this [cpan.org]. Though I do like the idea of distinguishing the three constructs by font!

          • Given SMU (Symmetric Multi-Universe) hardware parallel programs should run in constant time

          <damian> Perl 6 will have junctions (the successor to quantum superpositions). Whether Parrot is ported to the necessary hardware, and whether the Perl 6 compiler is able to emit Parrot code that can take advantage of it are both, of course, entirely up to Dan's team. ;-)
