[perl #128154] [BUG] Cannot use qqx in rakudo star on windows7
I found resolution. It looks like it is problem windows locale issue than perl itself. Running command chcp utf8 Makes work just fine. Default is 852. I'm very supprised because I use unicode encoding all the the time and never had such issue. For me it would be better to detect if codepage is set to 852 and warn user that perl6 may not work well. Shall we close it or leave defect for future improvement?

In perl6 default way is to not write new, BUILD or BUILDALL and also not to write accessors. When you create object you can provide attributes to initialize, default accessors are generated if field is declared with $. sigil. OOp was designed to not write the same code everytime. When I started using perl6 the doc didn't told me it but IMHO the best way to learn is read others code. > I haven't been able to find any guidance on when I should be using a role and > when I should be using a class. The former seem to give you better error > messages when you forget to define a method from a base role... So never use > classes? I suspect it's more complicated than that. Roles are similar to mixins. You can add something to class without all complications of multi inheritance. IMHO *is* and *does* keywords in most cases explain best whether you want class or role. I generally use classes for data and roles for code because I like to separate data form implementation. I hurt a lot of times while was trying to do java programming with perl6 then I realized roles are not interfaces and code is not compiled in static language sense. -- Regards Kamil Kułaga

Diffrence between is and does in scope of overriding multi methods
Hi,
I would like to ask for help in understanding difference between this code:
use v6;
role X {
multi method xyz(Any $a) {say Class X}
}
class Y does X {
multi method xyz(Any $a) {say Class Y}
}
say Y.new.xyz(1);
$ perl6 tst.pl
Ambiguous call to 'xyz'; these signatures all match:
:(Y: Any $a, *%_)
:(Y: Any $a, *%_)
in block at tst.pl:26
And this code:
use v6;
class X {
multi method xyz(Any $a) {say Class X}
}
class Y is X {
multi method xyz(Any $a) {say Class Y}
}
say Y.new.xyz(1);
$ perl6 tst.pl
Class Y
True

Re: Diffrence between is and does in scope of overriding multi methods
Hi Timo,
After I read your explanation and now it is even logical to use role
punning in my app. In most cases I don't want to override this default
behavior of method xyz but I would like to add new specific one. Only
one class does opposite so it should be subclass of a role.

It is hard to google such common words like is and does :)
Hey Kamil,
What happens when you does a role in a class, you mix in all the methods
at the same level, basically as if you had copy-pasted the method
declarations over. That's why you get the error that the call to xyz is
ambiguous.
When you is a class, you derive from it. That's why the multi method
X::xyz gets overwritten by Y::xyz, as the signature is identical.
At least that's my understanding.
Btw, you can also is a role, in which case it will get punned into a
class. That operation is equivalent to declaring a class with an empty body
that does the given role. So in the upper example, with role X and class
Y, you could is X and get the same behavior as in the lower example.
Hope to help (and hope what I wrote is actually accurate)

Re: Code execution during compilation
Ok,
I've read SYN-04 Phasers and I think I should use INIT {} or END {}
Are there any situations INIT {} / END {} will not postpone execution?
Because in my case it is still executed during compilation

Hi,
class and role bodies are executed at compile time, so yes, that's
expected. The same thing happens in BEGIN blocks.
(Actually, the case with roles is more complicated; iirc their bodies
are executed at role application time, but in your example, 'class B
does Xx' runs at compile time, so the two are roughly equivalent).
Cheers,
Moritz

I think the problem is that categorize will call your inner code block for
every item in the @array. Then you map your {[.a, .b]} over that item, so
you end up with a single-item list as a result. Could that be the problem?

Rewrite using map? Trasformation array into hash of hash
Hi,
I was wondering whether following code can be rewritten using map/grep
construct.
class A {

has $.b;

A.new(a='a', b='22'),
A.new(a='v', b='33'),
A.new(a='w', b='44'),
A.new(a='v', b='55')
);
my %hash;
for @array - $elem {
%hash{$elem.a}{$elem.b} =$elem;
}

Re: Rewrite using map? Trasformation array into hash of hash
Dear Timo,
I'm almost done with categorize. I stole similar example from rakudo
tests but I can't get rid off array on end. If I remove from map []
it stops working.
PS. I barely understand code I wrote anyway :)
$ perl6 ~/xx.pl
[A.new(a = a, b = 22)]
Reference
A.new(a = a, b = 22)
use v6;
class A { has $.a; has $.b };

A.new(a='a', b='22'),
A.new(a='v', b='33'),

Dear Kamil,
the method categorize, as specced in
http://perlcabal.org/syn/S32/Containers.html#categorize will allow you
to return a parcel from the categorization you provide (such as - $_
{ (.a, .b) }) and build a multi-leveled hash.
Sadly, I wasn't able to make it work right away.

Re: Is passing excess parameters while creating object legal?
Hi Tadzik and timo,
Timo: Thanks for pointing information in synopsis. Now I understand
why it works this way.
Tadzik: Actually I used this as a feature in my

will stop working with some rakudo update but StrictConstructor in
some other cases may be a great idea.

Hello Kamil,
Why the behaviour above is correct and documented, you may find it bug-prone
or inconvenient. To address that, I've ported MooseX::StrictConstructor to
Perl 6[1]. Here's example usage demonstrated on a piece of code similar to
yours:
use v6;
use ClassX::StrictConstructor;
class PersonalId does ClassX::StrictConstructor {
has Int $.number;
has Str $.full_name;
}
PersonalId.new(number = 7,
full_name = Edgar Poe,
yada = 'yada');
# Output:
# The following attributes are not declared for type PersonalId: yada
# in method new at /yada/yada/StrictConstructor.pm:32
# in block at test.pl:9
It may come to your liking :)

Re: Does perl have ensue override?
Hi Moritz, Couldn't this be achieved by custom made metaclass? I was trying to adapt examples from advent calendar and S12 and I lost :( because my metaclass is not used by perl https://gist.github.com/teodozjan/b7183c81c966cfeee3bd#file-incomplete-pl On Mon, May 19, 2014 at 10:36 PM, Moritz Lenz mor...@faui2k3.org wrote: Hi Kamil, the good news is that I understand what causes the problem. The bad news is that it I don't have a solution yet. The trouble is that you can't really call methods on roles; roles are rather abstract things, and if you try to call a method on a role, Perl 6 automatically creates a class for you, with the same name as the role. We call this process punning. Calling R.^can($methodname) causes punning, and the punned class doesn't implement the stubbed method. Thus the error message. Knowing that, one could just inspect the role's method table instead of calling .^can. However that's not so easy, because roles come in groups. Roles can be parametric, and multiple roles of the same name can be parameterized by different signatures, and applying a role to a class (possibly with a list of arguments) selects a candidate role, not just a single role candidate. So far I haven't seen any method in the ParametricRoleGroupHOW that gives me a list of those candidates, or a of methods. So I don't know how to emulate .^can. I'll see if anybody in #perl6 (IRC) has a good idea...

Problems importing JSON::RPC::Client while in lib instead of bin
Hi, I have no problem while importing JSON::RPC::Client directly in script but when I try to move it into lib (the compiled ones) i get /STable conflict detected during deserialization/. Am I doing something wrong or there is a bug? For easy reproduce I've created repository https://github.com/teodozjan/sandbox I use rakudo compiled from repository. Deleted everything and built different backend but it did not help. kamil@perl6:~/dev/sandbox$ ufo WARNING: You need to re-run ufo whenver you update to a new Rakudo version kamil@perl6:~/dev/sandbox$ make install mkdir -p blib/lib/Sandbox/ cp -p lib/Sandbox/Sclass.pm blib/lib/Sandbox/Sclass.pm PERL6LIB=/home/kamil/dev/sandbox/blib/lib:/home/kamil/dev/sandbox/lib: perl6-m --target=mbc --output=blib/lib/Sandbox/Sclass.moarvm lib/Sandbox/Sclass.pm mkdir -p blib/lib/Sandbox/ cp -p lib/Sandbox/Sclassb.pm blib/lib/Sandbox/Sclassb.pm PERL6LIB=/home/kamil/dev/sandbox/blib/lib:/home/kamil/dev/sandbox/lib: perl6-m --target=mbc --output=blib/lib/Sandbox/Sclassb.moarvm lib/Sandbox/Sclassb.pm mkdir -p /home/kamil/rakudo/install/languages/perl6/site/lib/Sandbox/ cp -p blib/lib/Sandbox/Sclass.pm /home/kamil/rakudo/install/languages/perl6/site/lib/Sandbox/Sclass.pm cp -p blib/lib/Sandbox/Sclass.moarvm /home/kamil/rakudo/install/languages/perl6/site/lib/Sandbox/Sclass.moarvm mkdir -p /home/kamil/rakudo/install/languages/perl6/site/lib/Sandbox/ cp -p blib/lib/Sandbox/Sclassb.pm /home/kamil/rakudo/install/languages/perl6/site/lib/Sandbox/Sclassb.pm cp -p blib/lib/Sandbox/Sclassb.moarvm /home/kamil/rakudo/install/languages/perl6/site/lib/Sandbox/Sclassb.moarvm kamil@perl6:~/dev/sandbox$ perl6 fail.pl ===SORRY!=== STable conflict detected during deserialization.

Unusual use of x string repetition operator
Hi, I've played wit x and xx repetition operators and found interesting result using rakudo star: join(|, (1,2) x 10) 1 21 21 21 21 21 21 21 21 21 2 Is this ok? If true please explain this to me :) Because I expected 12121212121212121212 or 12|12|12|12|12|12|12|12|12|12 PS. perl6 --version This is perl6 version 2014.01 built on parrot 5.9.0 revision 0 -- Regards Kamil Kułaga
Re: Unusual use of x string repetition operator
Hi, Array stringification to 1 2 mislead me that something more complicated comes around.

Re: Unusual use of x string repetition operator
Hi,
The best, because it uses object oriented join. I forgot about it.

A Parcel stringifies to 1 2. Then you used the string repeatition
operator x, and I think you want to use the list repeatition operator
xx instead.
FROGGS p: say join(|, (1,2) xx 10)
camelia rakudo-parrot 46234b:
OUTPUT«1|2|1|2|1|2|1|2|1|2|1|2|1|2|1|2|1|2|1|2»
Then again, you might want to do this instead:
FROGGS p: say join(|, (1,2).Str xx 10)
camelia rakudo-parrot 46234b: OUTPUT«1 2|1 2|1 2|1 2|1 2|1 2|1 2|1 2|1
