Perl 6 regexes via Pugs

schwenn

Dear Jonathan,

I am trying to learn Perl 6 regexes via Pugs. I have the current win32 binary build (which includes a parrot.exe) available from the pugscode.org .

I get a parsing error on the pattern of any Perl 6 regex example I try and I think it maybe because Parrot is not being embedded or externally linked properly into the pugs.exe. Are there some environment variables or pugs environment commands I need to effect to get parrot to get asked to parse for pugs?

The error I get for perl 6 regexes (eg. for an example:

$string= "abacadabra";

$string ~~ m/a(.*)a/; ) is

*** Cannot parse PGE: a(.*)a

It doesn't make any difference whether the pattern is a(.*)a or something simpler or more complex - pugs can't parse the regex pattern whatever it is.

By the way, if there's some OTHER way than win32 binary-build pugs.exe to try out perl 6 regexes I would be very grateful for that just as well.


Thank you,

Peter Schwenn

I fear, that's the one that I produce.

They actually don't use PGE any more, but switched to using PCR, and are embedding Perl 5. I think that my build was then missing some files needed to use regexes. I'm currently working on a fix for that - I'll get the new release up soon.

You can always download Parrot and play with PGE directly, but the easy way is to use runpugs:

Have fun,
