TimToady thou: the Set type is supposed to be immutable, because if you remove an object, it's a different set 00:12
thou ok, so just use $s .= difference()? 00:13
TimToady there's supposed to be a KeySet type that emulates a "mutable" set, but it's not implemented, I think
so I think just use a Hash for now
%hash.delete('key') in rakudo, since rakudo does not yet implement :delete 00:14
and I think the keys are only strings at the moment
set difference might work too
for small sets it's probably efficient enough 00:15
I think it does === semantics too, which is more what you want

sorear odd, S04-statements/goto.t tests I-don't-know-what and hardly goto at all 02:49
thou i'm getting this error: Type objects are abstract and have no attributes, but you tried to access $!key: Code is here, am I doing something stupid, or is this something unimplemented? friendpaste.com/6CFralb4xTPxsiXlEzGkHe 02:54
sorear that's... not how constructors work in Perl 6 02:55
thou ah
sorear "new" is just a static method 02:56
it doesn't have a usable "self", so it can't access $.key
02:56 pjcj left
sorear you could do my $new = callsame(); and then $new.key =, etc 02:56
02:56 pjcj joined
thou and then return $new at the end 02:57
sorear yes
alternately, nextwith(self, key => $key, val => $val, color => True)
this can be shortened to nextwith(self, :$key, :$val, :color) 02:58
thou ok, good! 02:59
sorear you could also add " = True" to has $.color 03:00
thou nextwith handles MMD and inheritance, right?
sorear yes
thou yes, i'm sure there's a bunch of tweaks i can make; i'm right now transliterating directly from the paper, and hopefully will get something working and then perhaps make it more perlish 03:01
sorear actually you don't want to use callsame() here, since Mu.new doesn't take $key and $val
it should be callwith(self)
thou the book has: return self.bless(*, :&callback, :@dependencies); 03:02
with a =for author what is * here?
but i haven't gotten to the synopsis that goes over this yet, so i'm kind of just shooting from the hip and hoping i guess right 03:03
which probably is a waste of your time, but i do appreciate the pointers.
sorear Mu.bless is basically the same as Mu.new 03:04
the main difference is that people don't override bless normally
also bless takes a first argument of *
the * is reserved for future use; there has been speculation that it will enable passing strings to pick alternate object storage systems 03:05
thou sorear: i switched to nextwith(self, :$key, :$val, :color<True>), and it now says: too many positional arguments: 2 passed, 1 expected (pointing at the Node.new($key, $val) call): friendpaste.com/6CFralb4xTPxsiXlEzGkHe 03:13
i also tried my $new = callwith(self); $new.key = ... 03:14
with the same result (2 passed, 1 expected)
maybe i need to study some actual code
i'll spend some time looking at modules.perl6.org/ 03:15
sorear: ok, for now i just deleted my new() method altogether, and call Node.new(:$key, :$value, :color<True>). thanks for your time! 03:19

moritz newbee: also you'll sometimes want to use non-rw attributes, then you *have* to use @!a. Better get used to it :-) 16:08
newbee i'm a little confused....$! mean "private" and $. means "public" ? 16:09
TimToady no, $. means abstract, and $! means concrete 16:10
but you're correct insofar as the general public are allowed to see only the abstract interface
and the implementation is not allowed to use the abstract interface until the concrete guts of the object are constructed 16:11
so you can think of them as public and private, but it's more like $. is a virtual method call, while $! is the actual storage slot 16:12
tadzik I always read $. as "has a public accessor"
TimToady which is virtual :) 16:13
tadzik and $! as "is an object attribute"
virtual in what way?
moritz but outside 'has', $.foo really means self.foo or self.foo.item or so
TimToady it calls back via self, which may be more derived than ::?CLASS
tadzik mhm
TimToady so your children are allowed to override the meaning of your attribute 16:14
sometimes you want to talk to your children, and sometimes you don't... :)
16:14 spq joined
tadzik the meaning of the attribute, or the accessor? 16:14
16:14 newbee_ joined
TimToady the meaning of the abstract attribute 16:15
newbee_ yes, but is better to think about it in terms of "concrete" and "abstract". All this time i was thinking on "public" and "private" hence my confusion
tadzik when in Perl, I rarely think Public and Private :) 16:16
16:16 newbee left, [particle]1 left
TimToady or think of it as "interface" vs "implementation" 16:17

newbee_ $! = attribute needed for the implementation; $. = "interface" attribute 16:18
TimToady or "de jure" vs "de facto" 16:19
newbee_ what if i want a variable to be both?
tadzik the second one is not a variable :> 16:20
btw: does $!a is rw; make any sense? 16:21
newbee_ example.... a class that analizes a text file. I want to specify on BUILD time the $!filename. But i want to change it later so the same object analizes another file.
tadzik newbee_: you can always change it later. But when you want a read-write accesor from the outside world, is rw is the way
rakudo: class Foo { has $.a is rw; }; my $a = Foo.new(a => 5); $a.a = 'b'; $a.a.say 16:22

JimmyZ thought one is public and another is private and there is no protected 16:28
TimToady public/private is more about different kinds of access to the same kind of thing 16:29
$! and $. are about different kinds of things
"physical" vs "logical" 16:30
"is rw" is more about access (but only controls write access)
JimmyZ they are more like lvalue methods ? 16:31
TimToady yes, you get readonly accessors otherwise

TimToady normal "logical" attributes declared with $. are "look but don't touch", whereas "$. is rw" is, er, more promiscuous... 16:35

newbee_ what does this error mean: "get_attr_str() not implemented in class 'Sub'"? 17:12
tadzik that means something is broken 17:13

colomon newbee_: what I'm trying to say is, most likely Rakudo responded to your broken code in a broken fashion. It's hard to get more specific without seeing the code in question. (And it might merely be a Rakudo bug, I've run into that message a few times recently myself.) 17:29

colomon by making it *@dates, you allowed the empty array as an option passing in
TimToady this is all bogus
new and BUILD take named params

TimToady *only*
colomon by process of elimination 17:46
default new, you mean.
TimToady I see no redef of new there...
colomon right, you're right about this code.
TimToady yes, default new, but BUILD is always called with named parames 17:47
