samcv ok i posted an answer 04:11
raiph samcv: cool. :) (I'm pretty sure the poster will complain that that's a workaround but you've got an upvote from me :) 04:17
samcv well it's not a workaround. it's. the official way heh
so you don't have to try and remember how it's going to parse 04:18
which is really just a way to be more compatible with perl 5 in the syntax
though your info about how it does decide was very interesting 04:20
when you overload things like brackets it's natural you'll have times where it does not make a hash. and that's happened a few times to me 04:23
also I think the brackets look a bit ugly as well :-)
raiph, reading the docs page i would disagree here: docs.perl6.org/type/Hash with '3) simply avoid the issue altogether by explicitly providing a name for the topic variable:' since i think the issue is not using %() and making the compiler have to guess 04:27

ugexe you can also upload your perl6 distributions to cpan through pause, and the source-url will be automatically set/changed. You can just download a tagged github release .tar.gz and use that (although you probably want to rename the file) 04:38

yoleaux 09:26Z <lookatme> Zoffix: So, about that questions on stackoverflow. As I know, Map not have a operator '<< >>'. What the parser treat '$map<<$n>>' as ?
Zoffix lookatme: it's a regular quoting construct probably documented somewhere on: docs.perl6.org/language/quoting 09:28
m: my $n = 'a b c'; dd «$n foo bar $n»; # don't need a map for it
camelia ("a", "b", "c", "foo", "bar", "a", "b", "c")
lookatme m: my $x = 10; << 1 2 3 "a" $x>>.WHAT.say 09:29
camelia (List)
Zoffix docs.perl6.org/language/quoting#Wo...tion:_qqww
lookatme But it's a list. Call A List on a Map .? 09:30
timotimo it gives you one value for each key in the list
just like with positionals and [ ] and a list
m: say (5..*)[1, 2, 10, 20, 100, 200] 09:31
camelia (6 7 15 25 105 205)
timotimo m: my %letters = "a".."z" Z=> 1..*; say %letters<<a b f g x y z>>
camelia (1 2 6 7 24 25 26)
timotimo lookatme: ^
lookatme So, '<>' works similar with '<<>>', as you said, timotimo
timotimo yup, <> doesn't do any interpolation at all, so if you want to have $foo as a key you have to use either { } or << >> 09:32
lookatme timotimo, Em, I know that, I just wonder '<>' is not a operator, how it works..
Zoffix lookatme: no, not call a List; it's just a shortcut for $map{«…»} just like $map<…> is a shortcut for $map{<…>} 09:33
lookatme Oh, my mistake '<>' is a operator , '<<>>
' not
Zoffix lookatme: it's parsed to call &postfix:<{ }> with the list from «» 09:34
perl6 --target=ast -e '%()«foo»' 09:35
lookatme Em, Zoffix that's a little beyond understand. Is there any document about that ?
Zoffix Look at last few lines at the end
No idea
and from postcircumfix:<{ }> it goes to github.com/rakudo/rakudo/blob/601c...ice.pm#L51 09:36

yoleaux 21 May 2017 13:13Z <lizmat> masak: judging from en.wikipedia.org/wiki/Multiset , it looks like we could have Baggy semantics for (<) and (<=), do you agree ?
21 May 2017 13:16Z <lizmat> masak: aka, "say <a b>.Bag (<) <a b b>.Bag" would be True rather than False (as it is now)
masak lizmat: interesting question. I will follow up on the link and get back to you.
11:38 Cabanossi left
masak lizmat: ok, that Wp page definition makes a lot of sense to me. 11:39

m: say <a b>.Bag.Set (<) <a b b>.Bag.Set
camelia False
masak (if you see what I mean) :)
I mean, I guess (without looking at Rakudo source) that that's what the current (<) does for Bags 11:40

   - Tests: github.com/perl6/roast/commit/125fe18489
masak only (small) downside I can see is that (<) used to be exclusively for Sets
lizmat yeah, I'm not sure of any spectest fallout just yet 11:41
masak kind of analogously to "+ is for Numeric", "~ is for Stringy", etc
but maybe that can be handwaved away by saying that a Bag is a fairly Set-like thing, I dunno
TimToady, what do you think? :)
lizmat but many other set operators have behaviours for Set/Bag/Mix
masak lizmat: ok, so there are precedents already? that makes it more OK, I think 11:42
lizmat feels to me that (<) and friends do not, is an oversight
m: say <a b>.Bag (^) <a b b>.Bag # an example
camelia bag(b)
lizmat m: say <a b>.Bag.Set (^) <a b b>.Bag.Set # with Setty semantics 11:43

samcv raschipi, was wondering your opinion on this github.com/softmoth/perl6-pod-to-m...own/pull/9 13:44
pmurias is passing the location of the rakudo-js runner "executable" and the location of the runtime library in env variables sort of sane?

pmurias samcv: one possible issue with :lang<perl6> is the question which version of Perl 6 is the snippet supposed to be in 13:51
samcv how would you improve the designation? 13:52
raschipi Not all markdown implementations get ``` for "code"
samcv yes i know
raschipi Is it supposed to be for a specific slang?
samcv well a lot of them do allow ``` for code 13:53
i mean it could always be hidden behind an option i suppose
raschipi Depends on what you're targetting.
13:53 Actualeyes joined
pmurias samcv: I don't have a solution 13:54
raschipi The project is targetting, I mean.
samcv i think a lot of people use it for github so i think it'd be useful to support fenced things which allow specifying a syntax highlighting language
could have a :no-fenced-codeblocks option or something for those who don't want it 13:55
raschipi If someone asks for it, then it might make sense to add an option. 13:56
13:57 skids joined 13:58 rindolf joined
raschipi Is the names of the languages specified anywhere or is it implementation specific? 13:58
samcv well there's standard lists of markdown tags 14:00
mst samcv: maybe :lang<perl6.c> ?
raschipi In my view this is specifing the exact output, it's not semantic, so I would use :fence<perl6> to get a fence block
samcv well pod doesn't have fenced blocks
oh you mean to the pod2markdown engine?
i mean that could make it assume that all the code blocks should be assumed perl6 even if they don't have config :lang<perl6> set 14:01
raschipi Oh, the tool only reads pod6, right
What's the ":lang" for, then? 14:02
I was actually looking at this one: github.com/softmoth/perl6-pod-to-m...409e639ecb
samcv raschipi, it goes in the pod 14:03
<samcv> well there's standard lists of markdown tags 14:04
oops
=begin code :lang<perl6

14:04 cdg left
samcv anything you put after key/value pairs becomes part of the 'config' for that pod block 14:04
14:04 cdg joined
samcv it seems mostly natural for language to be a config for a code block. though it doesn't have any mention in the spec. you can have any config you want for your uses /renderers. it's meant to be extensible 14:05
raschipi The classic way would be 14:06
=begin perl6
say "hi!"; 14:07
evalable6 hi!
raschipi =end perl6
wouldn't it?
Unsing the "=begin formatname " form 14:08
But it would also be overkill... 14:09
Is this supposed to write markdown with existing POD, or purpose-written POD? 14:10

and the inline family of modules... being built on vms, very forward thinking while leveraging so much past (often good) work! 20:48

granted, i regularly rant that if the united states spent it's military overbudgeting on medicinal research and ways to alleviate the cost of becoming a doctor.. that our medical system here wouldn't be so fubar... but i digree. 20:54

Yup. Both are reported on the /todo now 21:18

pilne: as someone who used to do perl5 only and perl6 was "about to be released", I felt kind of... fear. That what I do is useless, soon to be forgotten. That I'm about to have a useless skill on my resume. That I might have trouble at work with my current perl 5 apps, because no one supports the modules I use any more.... So, I don't think the post-smitting is warranted under such assumptions :) 21:23

pilne but wasn't there any comfort in the fact that languages like c and c++ have been prounced as "about to die" directly because of other languages, when, as far as i can tell, perl6 never stated that eliminating or replacing perl5 was a goal? i mean... there just seems to be so much hyperbole surrounding certain subjects and topics in programming, both the "science" side of languages and the "x vs. y" debate of the hour. 21:39

Zoffix pilne: not really. Just because it happened for X doesn't mean it'd happen for Y. And well, close to the time when I left Perl 5, it kinda felt emptier... I did notice people leaving and finding more abandoned modules, people saying in channels they won't start any new Perl 5 projects, etc. 21:40
^ docs; on positive side: that .split is now exactly like Str.split, with all the feature and none of own bugs 21:41

pilne i guess as a hobbyist, maybe looking to do something "real" if it just happens to work out with programming, i guess I don't have that fear of where's the money gonna come from 21:41
Zoffix mhm 21:42
pilne it's just sad, even in my environment, how buzz-wordy those higher up the chains are... my company will step over a dollar to pick up a penny... because shiny is the buzzword compared to ratty looking paper money 21:43
unless my analysis as an end user, who saw the internal "explanation" video, my company way overpaid for a cs101 level homework assignment.... 21:44
maybe like 201... i guess term length matters
Zoffix Lack of skill. People who know nothing about programming need to make I.T. decisions that will affect the company for the next 15-20 years. The buzz-words and marketing is what works for those people, not some nerd's opinion. 21:45
21:46 setty1 left
Zoffix Yeah, overpaid sounds about right. Sell a company a product that handles all of their business. Then charge $100,000/year for "support" because it'd cost them a $1,000,000 to replace you, so they eat the cost. 21:46
pilne so odd...
yeah, even though i don't think that's how these costs worked, they mentioned this specifically as money spent developing 21:47
i mean, i'm all for paying good money for good developers... 21:48

bioduds Please, how do I make an array of instances of a class? 22:07
bidimensional 22:08
I'm trying has Node @!node;
Node is the class
then inside a double loop I'm trying to assign @!node[$h;$i] = Node.new( data => $data ); 22:09
It's telling me Type check failed in assignment to @!node; expected BW::Merkle::Node but got Array ($[])
22:11 mcmillhj left 22:12 Zoffix joined
Zoffix bioduds: it's 'cause you're specified a parameterized array, not "array that contains only Node elements" 22:12
m: class Node {}; class Foo { has @.meows[2;2] where .all ~~ Node }.new: :meows[(Node.new, Node.new); (Node.new, Node.new)]
camelia ( no output )
Zoffix m: class Node {}; class Foo { has Node @.meows[2;2] }.new: :meows( Array[Node].new: (Node.new, Node.new); (Node.new, Node.new) ) 22:13
camelia ( no output )
Zoffix or keep it parametarized, but then you need to give it parametarizeadasdaij array ^
hm, does .all even work on shaped arrays? 22:16
m: my @m[2;2] where .all ~~ Int; @m = (4, 2), (3, 4); dd @m.all
camelia Cannot access 2 dimension array with 1 indices
in block <unit> at <tmp> line 1
bioduds I can tell on the constructor? The parameters [2;3] for instance?
Zoffix m: my @m[2;2] where .all ~~ Int; @m = [[4, 2], [3, 4]]; say @m.flat.all 22:17
camelia all(4, 2, 3, 4)
Zoffix ah, k, it might be `where .flat.all ~~ Node`
bioduds: so you want an attribute that accepts shaped arrays of arbitrary shapes?
bioduds yes 22:19
because it depends on the input
the size of the two dimensions, I mean
Zoffix m: class Node {}; class Foo { has Node @.meows; method !SET-SELF (\m) { @!meows := m; self }; method new (:$meows is raw) { self.bless!SET-SELF: $meows } }.new( :meows( Array[Node].new: :shape(2, 2), (Node.new, Node.new), (Node.new, Node.new) ) ).meows.perl.say 22:20
camelia Type check failed in binding; expected Positional[Node] but got Array[Node] (Array[Node].new(:shap...)
in method SET-SELF at <tmp> line 1
in method new at <tmp> line 1
in block <unit> at <tmp> line 1
Zoffix booo

camelia Array[Node].new(:shape(2, 2), [Node.new, Node.new], [Node.new, Node.new])
Zoffix That seems to do the trick; I'm unsure of a way to do that and keep the @ sigil
bioduds let me try that logic in
22:22 mcmillhj joined, espadrine left
Zoffix Just to be clear: it's not mandatory that you specify the shape. 22:23

Zoffix superstitious parens 22:36
m: my \c = 1..3 Z=> <a b c>; dd c
camelia (1 => "a", 2 => "b", 3 => "c").Seq
nadim_ the above looks nice but when I dump it, eg: I display each element of the Seq, I get this result: (1 a, 2 b, 3 c).Seq
Zoffix nadim_: that's 'cause you're stringifying those pairs when you dump them
lizmat m: say Pair.new("a",42)
camelia a => 42
lizmat m: say Pair.new("a",42).Str
camelia a 42
Zoffix m: my \c = 1..3 Z=> <a b c>; print c
camelia 1 a 2 b 3 c
lizmat .gist vs .Str 22:37
Zoffix is too slow :)
nadim_ thanks, I'll see how I can bypass the stringification
maybe time to test displaying Pairs
the problem is probably there 22:38

2 years effort now I think, but worth it, fo' sho'
... this all sounded better in my head. I meant only to bolster than notion that we were, y'know, 'prod ready'. But I should've waited until I sobered up. Or someone knew who the hell I was. Oh well! 23:18

pilne i think that currently (from what i've read) perl6 provides support for everything you'd do with macros already, just kinda separated out instead of all globbed together. 23:42
at least in terms of what scheme/lisp macros are used for. 23:43

pilne does a child have to implement all of the submethods of the parent to inherit it? or is it just a mechanism to "hide" them from the children classes? 23:45
23:45 ParsonsNose joined
pilne "inherit from it?"** 23:45
i like having inheritance available, and multiple inheritence for prototyping, but i prefer factoring it out into the "roles" style once the code and I come to a working agreement that i get what I want (: 23:48
i've never understood the problem with having more than one way to do something, as long as the code is either self-doccumenting, or well-doccumented... 23:51
probably a bit spazzy and gushing here, but i feel like a kid in a candy shop with this language 23:52
