| fridim_ | hi | 01:12 | |
| christopher | How do I disambiguate between class and instance attributes within a method definition? | 07:26 | |
| gaal | christopher: you mean if they have the same name? not sure, but probably $foo means instance and $ThisClass::foo means class. $.foo and $!foo certainly mean instance vars. | 07:31 | |
| (when I say "certainly" about language matters I usually mean "I would be quite surprised unless") | 07:32 | ||
| christopher | yeah, if they have the same name. So I say: our $.x; to declare the class attribute, but $Foo.x inside one of the instance methods? (where $.x would shadow with | 07:33 | |
| the instance attribute) | |||
| where Foo is the class name | 07:34 | ||
| gaal | I don't think you say our $.x | 07:35 | |
| say either our $x or my $x for public/private class data. | |||
| hopefully I'll be corrected if I'm wrong about this. | 07:36 | ||
| christopher | 'our $.x' is in S12, if you search for the string 'class attr' | ||
| gaal | hmm | 07:37 | |
| well, I don't know then. :-/ | 07:38 | ||
| christopher | I haven't actually seen $Foo.bar written anywhere. | 07:40 | |
| Foo.bar appears in t/oo/attributes/class.t, but that's for | |||
| the accessor by the same name, of course... | |||
| I suppose $::?CLASS.bar would be safe? | 07:42 | ||
| gaal | that would work if accessors had been created, that is if you declared it with a twigil. | 07:43 | |
| christopher | I want to access the variable, not the accessor (which may not be an lvalue sub) | 07:44 | |
| gaal | If not, $ThisClass::bar, for our vars at least. | ||
| Better ask Luke when he pops in. | 07:47 | ||
| christopher | You mean the . has to be replaced with :: to get past the accessor? | ||
| (since it doesn't work that way for instance attributes, I'm surprised.) | |||
| (I thought it was the leading sigil that determined whether you were | |||
| using an accessor.) | |||
| anyway, thanks! | 07:48 | ||
| Ah, it's illegal: | 08:06 | ||
| groups.google.com/group/perl.perl6....50cd740395 | |||
| (for there to be a conflict between instance and class attributes) | |||

evalbot_7961 is now known as evalbot_7968

| broquaint | I guess not. | ||
| raptorXXX | is there perldoc equivalent in haskell ? | 12:41 | |
| rafl | haddock | ||
| raptorXXX | wiki.perlchina.org/main/show/haskel...kshop+2005 | ||
| this can be interesting... | |||
| thanx | |||
| where is this haddock? | 12:42 | ||
| i cant seem there is such command .. ghc | |||
| aaa i see | |||
| theorbtwo | 1: I'm not quite sure I'd call them equivelent. | ||
| raptorXXX | it is in a package | ||
| theorbtwo | 2: It comes sepperately. | 12:43 | |
| raptorXXX | yep, thanx | ||
| gaal | raptorXXX: see also haskell.org/hoogle/ | 12:45 | |
| raptorXXX | :) thanx | ||
| one more questions...is there any equivalent of a Hash and HoH,AoA..etc.. structures in haskel | 12:48 | ||
| FiniteMap?! | |||
| SamB | raptorXXX: we usually use Data.Map since GHC 6.4 | 12:49 | |
| raptorXXX | aha..i see | ||
| FiniteMap is depricated | |||
| SamB | raptorXXX: what is an AoA? | ||
| raptorXXX | Array of arrays, HoA, AoH ..etc | 12:50 | |
| SamB | raptorXXX: just nest the types... | ||
| raptorXXX | ok.. i will try ,tnx | 12:51 | |
| SamB | so, like, Map String (Map String Int) or something like that | 12:52 | |
| there are a bunch of array types, though | |||
| raptorXXX | this haskell seem very cool, perl6 will stole alot of things isnt it :)) | 12:54 | |
| GeJ | erm, I guess the word you're looking for is "borrow"... sounds better :) | 12:55 | |
| raptorXXX | :) | ||
| theorbtwo | Or "steal", which has the correct tense. | ||
| SamB prefers "steal" | 12:58 | ||
| raptorXXX | i've read abit about Types in Haskell... do we have something like it in perl6 | 12:59 | |
| roles ? may be ? | 13:00 | ||
| theorbtwo | I think haskell types map more or less onto perl6 types. | 13:02 | |
| Not completely sure about parameterization, though. | |||

| evalbot_7968 | 5050 | ||
| xinming | hmm, should [1..100] be deferenced? | 13:11 | |
| theorbtwo | I don't think so. | ||
| rafl | ?eval [+] *[1..100] | ||
| evalbot_7968 | 5050 | ||
| theorbtwo | It should possibly be nummified, but possibly not. | ||
| (Since there was only one argument, the operator drops out, in one way of thinking.) | 13:12 | ||

| xinming | hmm | ||
| theorbtwo | Blink... when did we get a ~~ operator? | 13:25 | |
| theorbtwo smacks his head. | 13:26 | ||
| Um, like 3 years ago... I'm using a strange font, for me... | 13:27 | ||
| xinming | oops | 13:30 | |

| kolibrie | Juerd: yes sir! | 18:38 | |
| Juerd: my wife started your tutorial | 18:40 | ||
| Juerd | Good! We certainly need more female dvorak typists, because they tend to be much more succesful in convincing others. | 18:41 | |

| raptorXXX | how to use perl5 modules in pugs..? | 21:50 | |
| #!/usr/bin/pugs | |||
| use DBI--perl5; | |||
| is this correct.. | |||
| PerlJam | raptorXXX: what happens when you try it? :) | 21:52 | |
| raptorXXX | pugs: *** Can't locate DBI.pm in @*INC (@*INC contains: /usr/lib/perl6/i686-linux /usr/lib/perl6 /usr/lib/perl6/site_perl/i686-linux /usr/lib/perl6/site_perl /usr/lib/perl6/auto/pugs/perl6/lib /usr/lib/perl6/site_perl/auto/pugs/perl6/lib .). | ||
| at <interactive> line 1, column 1 | |||
| kolibrie | use perl5:DBI; | 21:53 | |
| raptorXXX | But this is ok :---> | ||
| use perl5:DBI; my $dbh = DBI.connect('dbi:SQLite:test.db'); | |||
| i see | |||
| so the second way is the correct one | |||
| kolibrie | :) | ||
| integral | did you find the "DBI--perl5" in a file in the pugs source? | 21:56 | |
| hmm, seems not :) | 21:58 | ||
| wolverian | integral, that was a suggestion on p6l - to put the perl version in the author field | 22:00 | |
| gaal | it used to work that way when the bridge was first put up. | ||
| integral | hmm? I know. I was just wondering where raptorXXX found the old syntax. I thought it might have been a presentation that was stored in the pugs tree. If it was I was going to fix it :) | 22:01 | |
| gaal | ahh ok | ||
| integral | it's in the 6.2.8 changelog :) | ||
| raptorXXX | no i read it | 22:02 | |
| wolverian | integral, ah, okay. | ||
| xgl | 'darcs get' seems improbably slow -- is it a known issue? | ||
| integral | raptorXXX: where? | ||
| raptorXXX | in haskell-workshop-2005 | ||
| wiki.perlchina.org/main/show/haskel...kshop+2005 | |||
| Khisanth | better to stick with the pugs docs :) | 22:03 | |
| integral | except where pugs is behind the design :) | ||
| Khisanth | integral: doesn't matter then, I don't think you can run perl6 anywhere else ... | 22:04 | |
| integral | hmm, that seems to just be a copy of autrijus' proposed paper for hw, which iirc is in pugs svn? | ||
| raptorXXX | where i can see more info for class-name-definitions 'cause i saw weird syntax .. one moment to find it | ||
| Khisanth | raptorXXX: docs/quickref should have most of these things covered | 22:05 | |
| raptorXXX | aha.. | 22:06 | |
| wolverian | ?eval 2**2 | 22:24 | |
|
22:24
evalbot_7968 is now known as evalbot_7969
|
|||
| evalbot_7969 | 4/1 | 22:24 | |
| wolverian | humm, what's up with the /1? | ||
| xgl | exit | 22:27 | |
| geoffb | wolverian -- that's a Rat, but I'm not sure why int ** int -> rat, frankly. | 22:30 | |
| maybe a coersion back and forth from a floating point rep. | 22:31 | ||
| wolverian | is it int ** int? | 22:32 | |
| ?eval 2 ** 0.25 | |||
| evalbot_7969 | 1.189207115002721 | ||
| wolverian | right, no /1 there | ||
| (yeah, I don't know enough haskell. :/) | 22:33 | ||
| SamB | well, if you do 0.25, doesn't that make it a float? | 22:34 | |
| well, in Haskell it just makes it some instance of Fractional... | |||
| leo | rafl: (inline-threading) the paper describes also a lot of plain code rewriting, which is (as proof of concept) already inside src/pic.c | 23:12 | |
| leo ponders about renaming .pbc to .pwc (.. word code) | 23:14 | ||
| (but that belongs better to #parrot ...&) | 23:15 | ||
