  • Ben Bullock commented on \d does not validate numbers

    Yes, I switched to using [0-9] almost everywhere. I think it's simpler.

  • Karl Williamson commented on \d does not validate numbers

    DEVANAGARI DIGIT NINE, for example, is used by millions of people millions, perhaps billions, of times a day as an essential component of their numbers. I don't know if you are being careless with your terminology, or wrongly arrogant about the place in the universe of [0-9].

    Unicode::UCD::num(), since Perl 5.14, can be used to make sure that a string of digits are all from the same script, so are not spoofing attempts, returning the numeric value the string represents, or undef if it is illegal.

    > That’s what /a is for.

    As a followup to this article, I am thinking about making another blog post showing how \d is used to match numbers in actual CPAN modules. It's used for number validation in more than a thousand modules, for example here is the matches for /\\d\./:

    and here is the matches for /\\d\+\./:*%2F%5Bb-z%5D*a

    Noting your comment, I tried s…

    Members of the Perl 5 Porters are working on your problem, but they need to interact with you. That will be much easier on list than here?

    Thank you very much.

  • David Mertens commented on SPVM is released! Perl maybe become much fast.

    I see: you're tackling the same problem as rperl does, but with a different implementation approach. In fact, you're using the exact same implementation strategy as Perl itself, but focused on a strictly typed Perl-ish language. As a bonus, you're making it very easy to call from Perl (something rperl claims to do as well, without the need of a compiler after the module has been compiled once). Code written in your dialect will run faster than a pure Perl implementation because the bytecode compiler and interpreter do not have to check nearly as many corner cases. Have you toyed around with…
