Re: Subset w/ Inline::Perl5 RE as constraint
Hi Bill,
Yes, that is exactly what I'm saying.
https://github.com/rakudo/rakudo/issues/2624
" FWIW, the :P5 supports a Perl 5 like syntax from X versions ago (probably
about 5.8, I would say)."
The features I need are in perl 5.10 which the :P5 adverb doesn't provide.
Thanks,
Paul

Re: Subset w/ Inline::Perl5 RE as constraint
Hi Paul,
I'm sorry, I don't understand.
Are you saying you're using Inline::Perl5 because you can't use the
"Perl compatibility adverb" :Perl5 or :P5 ?
https://docs.raku.org/language/regexes#Perl_compatibility_adverb
Is that what you mean when you say the "perl regex engine [in Raku] is
too old" ?
Thanks, Bill.

Re: Subset w/ Inline::Perl5 RE as constraint
So two example patterns are:
[\\u0009\\u000A\\u000D\\u0020-\\u007E\\u0085\\u00A0-\\uD7FF\\uE000-\\uFFFD\\u1-\\u10]*
[\\p{L}\\p{Z}\\p{N}_.:\\/=+\\-@]*
To note, the RE's themselves cannot be changed as they are fed externally.
Given that I'm stuck with these RE's which I believe are PCRE, It was my
hopes to lean on perl to do the evaluation.
Raku's perl regex engine is too old to interpret it properly, hence the
shenanigans with Inline::Perl5.
Thanks,
Paul

Re: Subset w/ Inline::Perl5 RE as constraint
I'm pretty sure you need to use single quotes for your example, as Raku
will replace the @_[0] before Perl has a chance to do anything with it.

Re: Subset w/ Inline::Perl5 RE as constraint
Can you provide some samples of what you are trying to match and exclude? There might be alternative solutions.
