diakopter most everyone has a usability threshold, whether or not they can/will pinpoint it

pmurias diakopter: why not translate STD mechanically? 00:17
00:18 ruoso joined
diakopter pmurias: b/c it's not possible... too much would be lost in a non-1-to-1 translation 00:18
so I'm porting over the declarative parts
00:18 Guest59956 is now known as Khisanth
pmurias diakopter: non-1-to-1? you mean you don't support all regex features? 00:19
diakopter if you include "arbitrary Perl 6 code in closures" in "all regex features", then no :P
pmurias you could translate a modified version 00:20
diakopter who does the modification
there are a lot of crucial semantics in the procedural/closure portions of tat grammar 00:22
that grammar
00:25 meppl left
pmurias diakopter: as long as you don't plan to write thousands of lines of barely readable js to duplicated STD (attempt to port more than a small subset of STD) i think it's ok if you do whatever you feel is right 00:26
diakopter heh 00:27
the grammar engine has to come from somewhere 00:28
it can't all be sent back through gimme5 at runtime
pmurias btw i think i'll do the SSA based optimalisations in mildew as my school Compiler Construction project 00:31

JimmyZ I thought it's a hash
moritz_ and it should be.
meneldor what means: No applicable candidates found to dispatch to for 'trait_mod:is' 10:32
moritz_ it means that you used 'is' somehwere (like in 'class A is B { ... }'), and something went wrong 10:33
nadim ng: my $a = 1 ; my $b ; my $c ; ($a, $b,$c) //= ('default_a', 'default_b', 'default_c') ; say "$a $b $c" ;
p6eval ng 2717d0: Null PMC access in invoke()␤current instr.: '!assign_metaop' pc 14406 (src/builtins/Junction.pir:147)␤
moritz_ for example B might not have beeen declared properly
nadim Is is just me or am I the only one this should work? my $a = 1 ; my $b ; my $c ; ($a, $b,$c) //= ('default_a', 'default_b', 'default_c') ; say "$a $b $c" 10:35
to think
meneldor well so if i say class A is B, B have to be declared above A?
because this is the error in my code 10:36
moritz_ yes
"I want to inherit from a class, but that doesn't exist yet"
meneldor and what if i want class A is B and Class B is A?
moritz_ what should that be good for? and what semantics should that have? 10:37
mathw How do you construct such a thing
moritz_ inheritance should be a directed, acyclic graph
mathw A has to call B's constructor first
Which then has to call A's
which of course needs to call B's
You can't have loops in your inheritance tree
Even if there's a hack in the language to make it work, it's a great way to go insane 10:38
meneldor i think i read somewhere that i can use loops
whatever now everything is fine :) 10:39
moritz_ std: class B { }; class A is B { }; augment class B is A { }
p6eval std 29557: ok 00:01 107m␤

meneldor im completely lost in the new p6 OO morel :) 12:20
model*
i've rebuild my game-like example from yesterday
lisppaste3 meneldor pasted "untitled" at paste.lisp.org/display/93609 12:21
meneldor so global_map consist everything
a player can have many castles
and units
castle can have many buildings 12:22
12:22 patspam left
meneldor so how can i create new player? 12:22
12:23 JohnDoe365 left
meneldor considering that in every moment the main object have to "know" for all players created 12:23
moritz_ lichtkind: I wanted to write something for iX, unless somdbody else does
meneldor how to create a new player and with him automaticaly to be added castle and hero, and all this to be stored in array or object so in every moment i can see how many players have been created 12:27
moritz_ can't parse "automaticaly to be added castle and hero" 12:28
meneldor paste.lisp.org/display/93609 12:30
there are classes Hero and Castle
they inherits from Player
moritz_ why is a Player a Map?
meneldor because i need one object to collect everything 12:31
and i think Map is on top
players play in the same map
moritz_ inheritance is a "is a" relation
so when you say Player inherits from Map, you say "Player is a specialization of a Map" 12:32
that sounds so wrong
maybe a player is on a map, but that's something very different
meneldor: en.wikipedia.org/wiki/Object-Orient...nstruction I can only recommend that, very good read 12:33
meneldor so the Player class has to be on top? 12:34
tnx moritz_
moritz_ the Player class should only be on top of things that are players 12:35
meneldor i look on Player like container for Hero,Castle and Unit belonging to him 12:36
is that wrong?
moritz_ what is a Player, and what is Hero? 12:37
12:37 lumi left, lumi joined
moritz_ can a player have multiple heros? 12:37
12:38 Guest6848 joined
meneldor yep 12:38
Hero leads the Units
PLayer is just the account who plays
the Player can hire many Heroes 12:39
they will create own Units
and so on
for example if you now the game Heroes3 12:40
:)
moritz_ I don't
lisppaste3 moritz_ annotated #93609 "other architectural approach" at paste.lisp.org/display/93609#1 12:41
meneldor well, when you start the game you have 1 castle and 1 hero
but later you can hire more
so the Player is the main container for all castles/heroes
12:41 ruoso joined
meneldor but the Map is the main container for all players 12:42
moritz_ ok
so class Map { has @.players }
meneldor ok considering you anotation, how to create a new instance of Player including new Hero and all this stored in @.objects ? 12:46
i mean which class have to be constructor for that
moritz_ class Player { ...; has @.heros = (Hero.new); }
and whenever you create a Player, you have to add it Map.objects yourself 12:47
meneldor thank you moritz_ i will try it that way 12:49
12:50 lichtkind_ joined 12:57 bluescreen joined
takadonet morning all 12:58
meneldor what means: invoke() not implemented in class 'Player' 13:03
moritz_ it means that you used Player() or so 13:05
and the () tries to invoke the thing
13:07 lichtkind left
meneldor in class Map: push @.players, Player.new(name=> "TestName"); 13:07
i use it that way
13:08 Guest6848 left
moritz_ then you need to write class Player first 13:08

TimToady well, technically, 1,2,3 isn't a list until it's bound to a positional. until then, it's a Parcel being used as a Capture. 16:49
if List.new happens not to bind it to a slurpy array, it's never a list 16:51
and arguably it's not a list after it's bound to an array either. well, it is, but it's not the array; it magically shows up as the hidden generator for the array. 16:53

jnthn Yes, I think it belongs in List. 17:16

17:23 meppl joined
ash_ really anything that functions on the an Array that doesn't modify the Array should be in list? logically speaking? 17:23
since the key difference between a list and an array is mutability

ash_ it waits to evaluate things until it has to 22:54
lichtkind_ oh you served by the superior beings :)
22:54 jferrero left
lichtkind_ ash_ and rakudo doesn't 22:54
jnthn Yes.
ng actually does object construction via a metamodel too.
erm, class construction
well, role too
22:54 KyleHa joined
jnthn lichtkind_: as in, lazy lists. 22:54
lichtkind_ jnthn: was that a yes or no? :) 22:55
22:55 lichtkind_ is now known as lichtkind
ash_ i don't understand the question.... 22:55
22:57 vinisterx joined
lichtkind ash_: the current rakudo is not lazy as in lazy list? 22:57
ash_ yesh, rakudo currently doesn't have lazy lists, rakudo ng branch does have lazy lists
lichtkind thats great info thanks 22:58
sjohnson OT question: anyone here enjoy the game of Chess?
lichtkind no thanks
but the rakudo-rx is a different branch? 22:59
Tene -ng 23:00
ash_ rakudo-master is the default version of rakudo, rakudo-ng is the place were most of the refactoring is taking place 23:02
23:03 hercynium joined, KyleHa left
lichtkind ash_: yes but isnt there a branch using PGE called rx ? 23:06
ash_ i think your thinking of nqp-rx 23:07

pugs_svn r29566 | jnthn++ | [t/spec] my method foo() { ... } is no longer equivalent to method !foo() { ... } in the current spec; remove this fossil. Also fudge a test I'm not sure about on role-private methods - needs spec review too. 23:09
lichtkind ash_ yes thats it 23:10
im back and was away for some time
so still dont know the new words
vamped sjohnson: occasionally
lichtkind so nqp rx includes PGE
will it be inside rakudo *? 23:11
dalek kudo/ng: c38b531 | jonathan++ | src/Perl6/Actions.pm:
The !foo operator also needs to be sensitive to quoted methodop form.
kudo/ng: 35d01c1 | jonathan++ | t/spectest.data:
We now pass the updated S12-methods/submethods.t.
23:11 huf joined, arnsholt joined, jnthn joined 23:12 LionMadeOfLions joined, tomaw_ joined
ash_ i believe that rakudo's ng branch will be rakudo* hopefully 23:12
PerlJam ash_: no, rakudo's ng branch will be master shortly. 23:13
23:13 sjohnson joined
PerlJam rakudo* will be a Perl 6 distribution based on rakudo. 23:13
jnthn *blink*...I had a re-join?
23:13 nihiliad left
jnthn ash_: ng has a lot of the stuff we need for Rakudo *, but we plan to merge it as soon as it's ready. 23:13
So it'll have testing and additional development before Rakudo *. 23:14
ash_ yeah, i meant that it will be master soon, and Rakudo* is going to be based off of that
jnthn right.
lichtkind jnthn: i was stillasking as yesteray if nqp-rx will make it into rakudo*
and i asked if nqp-rx included PGE 23:15
23:15 lumi left, lumi joined
jnthn lichtkind: nxp-rx replaces PGE. 23:16
ash_ well nqp-rx is built into parrot now
PerlJam lichtkind: nqp-rx does parse regex, yes. And, if nothing catastrophic happens, Rakudo* will use nqp-rx (because that's essentially the function of the ng branch--to use nqp-rx)
jnthn lichtkind: The ng branch is using nqp-rx already.
23:16 gabiruh joined, ssm joined
lichtkind THANKS a lot i beginning to understand 23:17
PerlJam lichtkind: before there was PGE + NQP, now there's just nqp-rx which does both (and a little more :)
lichtkind what more? 23:18
sjohnson darn netsplits
jnthn lichtkind: protoregexes, contextual variables, closures in regexes... 23:19
...to name the most important.
23:19 skeptical_p left
lichtkind jnthn: that are features that has nqp-rx? 23:19
23:20 stephenlb joined
jnthn lichtkind: yes 23:20
lichtkind i just ask to not confuse it with what one can parse :)
jnthn :-)
Hmm. Looks like two probably smallish fixes and we can make it through S12-methods/instance.t again in ng. 23:21
Seems there is starting to be some light at the end of the tunnel...
23:23 pnate2 joined
ash_ jnthn: do you know if @( ) is supposed to be working in ng? 23:23
jnthn ash_: I don't remember making it work, or having seen it working. 23:24
So my guess is no, but it's possible pm put it in or someone else.
ash_ jnthn: ah, well i don't think it works, i was just going to let you know, but if its not implemented then yea 23:25

jnthn oh
ash_ should be 1\n2\n3
jnthn Yeah, I think so.
ash_ i'd expect
rakudo:

p6eval rakudo 726b83: 1␤2␤3␤
jnthn I'd check pmichaud or TimToady agree though, they have a better grasp on that than I...
lichtkind jnthn: what are the core devs beside you and pm? 23:29
23:30 Khisanth joined
ash_ jnthn do you know any other way of turning $a = 1, 2, 3; into an @ then? 23:31
jnthn ash_: I think @($a) *should* do it - I'd just rather get a second opinion. :-) 23:32
ash_ oh, okay, yeah, i have only seen afew tests that use @()
