need p5/p6 :: help

Hi All, I am in the process of converting a YUGE program I wrote in Perl 5 to Perl 6. I used "xx::yy" at lot for readability so I could tell where something came from. I take it "::" means something different is Perl 6 than Perl 5. $ p6 'use lib "/home/linuxutil"; use PrintColors; PrintColors:

Re: need p5/p6 :: help

It's important for the PrintRed sub inside PrintColors to be declared "our", otherwise it is "my" scoped, i.e. limited to the lexical extent of the module file. On 14/09/2018 12:59, Todd Chester wrote: > Hi All, > > I am in the process of converting a YUGE program I wrote in > Perl 5 to Perl 6.  I

Re: need p5/p6 :: help

lexical means it is only available within that scope, or in sub-scopes { my $a; { $a = 42; } } $a # error { sub foo (){} # my sub foo (){} # identical { foo(); } } foo() # error --- Note that sub foo (){} is really short for my only sub f

Re: need p5/p6 :: help

It thinks it's interpolating a variable $x::... and then it gets stuck because it sees $y instead of the rest of a variable name. You can use braces to control what's part of the name: pyanfar Z$ 6 'my $x = "abc"; my $y = "def"; say "{$x}::{$y}"' abc::def Otherwise, you couldn't interpolate the n
