nine emilbarton: a fixed version ^^^
emilbarton yes I forgot Classx. but that's not the point, it still answers idem 07:00
nine emilbarton: the error is in the has Class1 $!classref; That creates a private attribute which the default constructor does _not_ set. You have to make it public or to add your own BUILD method to initialize it using the parameter of the constructor.
07:01 abraxxa joined
nine emilbarton: doc.perl6.org/language/classtut#Constructors 07:01
emilbarton nine: I thought there was no real public attribute in perl6 ($.classref does n't help) 07:02
nine emilbarton: that's sort of true. The attribute itself is still only accessible through the accessor methods. But those are generated for you by declaring it as has $.classref; and this also tells the constructor to initialize it. 07:03
m: class Class1 { has $.foo = "foo"; method my1 { self.foo; } } ; class Class2 { has Class1 $.classref; method my2 { $!classref.my1() } }; my Class1 $C1 = Class1.new(); my Class2 $C2 = Class2.new( classref => $C1 ); $C2.my2();
camelia ( no output )
nine emilbarton: also a reference to a class instance is more commonly referred to as "object". 07:05

timotimo it seems like i didn't push the manual change to the CALLER::CALLER:: stuff 09:04
and i also didn't start implementing the optimization in the static optimizer 09:06
another thing is that my manual optimization didn't factor out the CALLER::CALLER:: into a single lookup yet 09:07
that could also give a tiny performance boost on top of what's already there 09:08
though of course the nqp ops that access the lexpad "directly" aren't nearly as expensive as allocating a pseudostash or something like that 09:09
09:31 laouji left 09:34 laouji joined 09:38 ChoHag joined
ChoHag I have (want) a class which has a Foo attribute. A Foo can be created from a string (and a string created from a Foo) so Foo has a method new (Str $newfoo) { ... }. How can I create an attribute so that the class using it will create it from a string without needing to manually create a Foo? 09:43
yoleaux 1 Sep 2015 20:46Z <TimToady> ChoHag: irclog.perlgeek.de/perl6/2015-08-30#i_11144152 looks like a bug to me, since .= is sugar for assignment, and assignment is supposed to be eager; please file a bug report, if you haven't already
timotimo do we still have the COERCE multi sub? 09:44
ChoHag ie. how can I enable the ability to say Bar.new(foo => "Something") rather than being forced to say Bar.new(foo => Foo.new("Something"))?
timotimo well, with a .new it's very easy
if all else fails, the constructor can do the conversion for you
and you can have a Proxy for your attribute that does conversion as well
so no tricky business needed even in that case 09:45
does that help, ChoHag? 09:47
if Str had a method "Foo" on it, you can just set the type of $.foo to be Foo(Str) 09:48
you can augment Str to have that method, but subclasses of Str won't have it (like IntStr, NumStr, RatStr, Complexstr)
ChoHag No, I want to be able to use it in locations other than another class' attribute. 09:49
ie. my SpecialString $foo = "normal-string-but-fooified". 09:50
timotimo unless you declare $foo to be coercive (like Foo(Str)) that won't work
ChoHag my SpecialString(Str) $foo? 09:51
timotimo yeah
that will call .SpecialString on anything that's Str
09:51 laouji left
ChoHag So can I have something like ReallySpecialString which stands in for SpecialString(Str)? 09:53
timotimo there used to be something that'd allow you to declare coercions as a multi sub, but that has the problem that unless you export that multi sub into other scopes, the coercion wouldn't work there
good question
m: constant CToInt = Int(Str); my CToInt $foo = "100"; say $foo.WHAT 09:54

timotimo oh, i didn't know that doesn't work
that seals it, then
ChoHag Well basically what I have/want is an object which can search through a bunch of linked items. The search object needs to be passed around/stored in various places, and the original string needs to be obtainable from it. 10:00
And basically I want to be able to provide a regular string in all the places the search object is expected and have it magically turn into a search string for me. 10:01
Pretty basic.
gfldex ChoHag: did you consider to subclass Str? 10:02
timotimo doesn't really help to make the code simpler there
there's a module that'll let you change how literals are created, but that'll really only enhance your literals 10:03
and it'll enhance "all" literals
what you can do is mix in a role to improve your Str into the SearchStr 10:04
10:04 lizmat left, lizmat joined
ChoHag role Magic { ... }; class SearchStr is Str does Magic { ... }? 10:04
timotimo not even that 10:05
role Magic { ... }; my $foo = "foobar" but Magic;
10:05 espadrine joined
timotimo sub searchWithMagic($inputStr is rw) { $inputStr does Magic unless $inputStr ~~ Magic; ... } 10:05
10:10 laouji joined
ChoHag So anywhere I need a magic string but can coerce to one from a regular string I need to do so explicitely? 10:11
timotimo seems so 10:12
ChoHag Sticking to constructors then, how do I enhance this: 10:13
m: role Magic { method end { "knob" } }; class Wizard { has Magic $.staff }; my $rincewind = Wizard.new(staff => "wizzard");

ChoHag Is there any advantage to the ternary rather than a multi method which distinguishes between Str :$staff and Magic :$staff? 10:23
grondilu suspects using a multi is better a choice 10:25
because possible compile time optimizations or something 10:26

moritz I'm sure *that's* a bug
and somehow it smells like the same (or a similar) issue

moritz my @sane = grep { !/\s/ }, @list_of_potential_usernames
ShimmerFairy: it's not negating the regex, it's negating the result of the regex match
ShimmerFairy moritz: but it reads like negating a regex. I'd argue that you shouldn't expect it to work in the first place.
(and fwiw I still think not using ~~ to match against a regex is kinda weird :P) 13:10

ShimmerFairy moritz: regardless, it looks to me like you're negating the regex. It'd be like claiming that !"str" didn't negate the string, but rather negated the result of doing $_ eq "str" 13:14
moritz ShimmerFairy: ! simply negates the boolean value of whatever comes after it
ShimmerFairy: and the boolean value of a regex just happens to be the match against $_

timotimo yeah, /foobar/ isn't the regex, it's an application of the regex already
otherwise you'd write rx/.../ or regex { ... }
ShimmerFairy moritz: that's far too magical a boolean value for my tastes.
m: $_ = "abc"; say ?rx/def/ # then this shouldn't fail, if rx// is meant to be an unapplied regex, no? 13:16

13:37 pippo left
masak ShimmerFairy: as another data point, I have no problem with reading !/\s/ in the intended way, as "match $_ against /\s/ and negate the result" 13:39
ShimmerFairy: to be more precise, there are many situations in Perl 6 (and Perl 5) where a regex stands in for its match result
ShimmerFairy: I agree that it's one thing we could aggressively wash that out of the language (like we are slowly doing with implicit flattening everywhere). but I just don't see the reason. 13:40
eiro thanks moritz... i realize i have to make those terms appear in my slides 13:41
jdv79 wash out topical? 13:42
eiro since [+] ^5; why not [&say] ^5 ?
masak jdv79: wash out auto-matching regexes. 13:44

ShimmerFairy jdv79: no it doesn't, you can always do $_ ~~ /.../ (I myself have never done without using ~~, as far as I can recall) 13:46

Ven heh.
eiro i'm so excited about [] i hopped we could use a function there 13:52
masak eiro: the parser needs to decide whether the thing it's seeing is a reduce metaop, or an array. 13:55
eiro: [42] is an array. so is [[[[1]]]]. so is [&say]
eiro: only if it sees an infix op in there does it go the metaop path.
13:57 TEttinger left
eiro masak, thanks for those lines 13:58
masak eiro: in general, if you need to reduce on a function, I'd recommend using the .reduce method on lists/arrays. 14:00
m: sub foo($l, $r) { 5 * $l + $r }; say [1, 2, 3, 4].reduce(&foo) 14:01
camelia rakudo-moar 92be57: OUTPUT«194␤»
eiro that's what i'm trying to do right now.
masak eiro: the reason what you were trying is kind of hard is that there *should* be a barrier between the op and function namespaces 14:02
or rather, between their usage syntax
eiro i got it ... not the deep way (i need years for that) but a "pragmatic" way. 14:03
the thing is: whenever there is a operator, i prefer it over the method call 14:04
masak remember that locally, in your lexical scope, you can always create all the functions and operators that you need 14:05
that means you get your wish inside that scope, without screwing up the environment for everyone outside of that scope
more and more I do this, and I really like that Perl 6 supports this in a big way by making a lot of things lexical
eiro i already love it too :) 14:08
PerlJam It's funny to me how "lexical" plays an important role in the 5 -> 6 transition just like it did in the 4 -> 5 transition. 14:09

nebuchadnezzar in the “for” case, “@a” and “@a,” are different, but in “push”, “@b” and “@b,” are the same 15:05
masak nebuchadnezzar: I believe there's been some very recent (as in yesterday) change there.
nebuchadnezzar: .push has split up into .push and .append, IIUC
nebuchadnezzar erf, should read in the git repo 15:06
masak nebuchadnezzar: to reduce the number of special cases of the kind you're confused about
nebuchadnezzar masak: thanks
I thought I understood but in fact not, I see the consistency between “for (@a,)” and “[@a,]”, but not with the “@a.push: @b,” 15:12
hmm, MoarVM september is out, need to package it 15:13
skids nebuchadnezzar: it was decided it was best if pop always got the same things that were pushed, so if you want the consistency, use append. 15:14
(or I guess you have to choose between one of two different consistencies. :-) 15:15
