jnthn masak: Just fine. Made a little trip to Trnava today to relax a bit. 18:31
masak nice.
jnthn Ate way too much Slovak nom.
18:31 patmat joined
masak I know the feeling. 18:31
I've been celebrating a friend's 30th birthday this weekend. ate way too much moose pie. 18:32
jnthn Mmm. :-) 18:33
masak indeed.
moritz_ moose pie? 18:34
jnthn use Moose;
;-)
masak moritz_: from a moose he'd shot himself, no less.
jnthn masak: I didn't ever eat moose. I can only guess it might be a little like yak. 18:35
s1n moose pie? sounds like cow patty :/
masak jnthn: I'll confirm or deny this as soon as I've eaten yak.
18:36 eternaleye_ left
masak s1n: comparing it to cow patty doesn't do it justice by far... 18:36
18:36 eternaleye joined
s1n still doesn't sound appealing 18:36
masak well, it was. I had way too much seconds, and got caught by surprise by dessert. 18:37
anyway, I spent most of today getting back to my home town today. the bus companies made sure, like only they can, that the first bus was late, and the second one on time. :/ 18:38
jnthn masak: So did you outsourced your bus service to a UK railway company, or did the UK outsource its railway service to a Swedish bus company? :/
jnthn had numerous stories like that from the UK railway network when he lived there 18:39
masak jnthn: I'm not sure public transport incompetence is limited to the UK.
jnthn: that said, there's no such thing in Sweden as "the wrong sort of snow" :P
there is, however, "leaf slippage" :/ 18:40
jnthn Huh? Leaves are a common excuse in the UK too!
They even spent money on an ad compaign about why it's such a hard problem. 18:41
18:41 kirillm_ left
masak anyway, once the bus company realised what they had done today, they tried to bribe me complacent with a gift card. I accepted, since I wasn't that inconvenienced anyway. 18:42

moritz_ no, it was not
it should read them as separate lines 18:56
what about a simple anthem.txt and a shell redirect?

moritz_: well, that works, I guess.
moritz_: but I'm curious why this doesn't.
moritz_ it's a rakudobug actually 18:58
rakudo: say $*IN.lines(1)
p6eval rakudo cddb16: OUTPUT«Land der Berge, Land am Strome,␤»
masak moritz_: one that having an external file would fix?
moritz_ no
it's get() which still has the magic context dependent behaviour 18:59
masak moritz_: I'm neither for or against moving it into an external file.
moritz_ when it was s/readline/get/ in the spec I did the same in rakudo
which was not really correct, but a quick 80%-fix
masak: whatever works for you
masak moritz_: not sure I understand by your explanation what's wanting with .get 19:01
do I understand you correctly that an easy fix was applied in the s/readline/get/ shift, and that a bug persists until a slightly more involved fix is applied? 19:02
jnthn moritz_: Confirm all the failures you saw.
moritz_ masak: yes. currently .get returns all lines in list context, it should return always just one
jnthn IOIterator needs to die. 19:03
masak moritz_: ok, gotcha.
moritz_ there were so many commits since Thursday that I can't say what broke it 19:05
not without bisecting
skids jnthn: it should be safe to try INITIAL_BUCKETS=4 if you apply parrot trac#636 19:06

moritz_ oops
it doesn't autoquote 19:11
masak so, it's a pure synonym of C<,> ?
jnthn rakudo: sub whatever { say @_.join('|') }; whatever('a' p5=> 'b', 'c' p5=> 'd');
p6eval rakudo cddb16: OUTPUT«a b c|d␤»
jnthn suspects the fix to join that pmichaud added
Or something related to that. 19:12
aye
is (1..5 Z <a b c>).join('|'), '1|a|2|b|3|c', 'Ranges and infix:<Z>';
That's from another file with failures.
moritz_ I always thought that p5=> did autoquoting, but created a list, not a Pair 19:13
jnthn moritz_: The test file says:
# S03:1465 says that p5=> is the same as a comma
# We'll test that it doesn't quote the LHS.
isnt(eval('my @arr = abc p5=> def;'), <abc def>, 'p5=> does not quote the LHS');
moritz_ ah
jnthn but the test looks bogus
because I figure the test meant to quote the rhs
At the moment it tests that neither are quoted rather than just the LHS. 19:14
(auto-quoted, that is)
moritz_ right
using a sub should be cleaner
jnthn well, abc p5 => "def" would do it
moritz_ "arguments come in as positional pairs rather than named arguments." - uhm, if it doesn't construct a Pair, how can they come in as pairs? 19:15
jnthn lol fail 19:16
I'm guessing it musta menat pairs as in "one argument after the other" rather than Pairs. 19:17
moritz_ presumably

moritz_ that was the second git-svn repo that I worked on during the weekend ;-)
masak moritz_ strikes again!
moritz_ no, that was moritz (without the _) ;-) 19:19
TimToady: in r26617 you changed some `ok try({...}), "text"' to `ok try { ... }, "text"' - that's wrong, because try is not an unary prefix (or it was not, last I looked), so ok() only gets one argument 19:22
TimToady: but I find that behaviour of try rather unintuitive 19:23
masak moritz_: ah, like a secret identity? :) 19:27
moritz_ very secret, yes ;-) 19:28
jnthn: you pinged me on Friday... was the timeout larger than two days? ;-)
s1n who's been working the IO stuff lately? 19:31
moritz_ git blame/svn blame is your friend ;-) 19:32
{git,svn} {log,blame} 19:33
masak I bet it's that Old McDonald guy who's been working on the IO again...
moritz_ it really depends on what you mean. Spec? Implementation? Tests?
masak Projects?
moritz_ bugs? ;-) 19:34
masak I've been working on "IO stuff" in proto, Druid and November, chasing Rakudo...
patmat i'm a newbie to perl6, how can i make a blank or a comma between the result in this example?
www.pastie.org/466928
s1n masak: do you know what happened to readline?
patmat the right format for the array
moritz_ s1n: $*IN.get
patmat: @list.sort.join(', '); 19:35
s1n moritz_: was the spec updated to reflect that or is the current IO not in complete wrt getline?
jnthn moritz_: I think I was going to ask about some tests, but I figured out what to do with them...
moritz_ jnthn: ok
masak s1n: I think readline went away.
s1n goes off to check the spec
masak s1n: now known as .get instead.
jnthn Some tests relied on wrong behavior of eval up to now. 19:36
moritz_ jnthn: the namespace thing?
jnthn moritz_: Ah, yes, that was it.
moritz_ well, since nobody implemented it correctly - not surprising at all
masak patmat: also 'say @list.sort.perl' is your friend.
patmat moritz_ thank you! 19:37
jnthn moritz_: No, not surprising. And not hard to deal with.
moritz_ rakudo: say (3.4).int
masak patmat: also, 'for 1..$zahl.sqrt' is much simpler than that C-style loop stuff.
p6eval rakudo cddb16: OUTPUT«3␤»
jnthn And IIRC just the one file.
s1n masak: .get is for the IO::Readable::Encoded, does $*IN accept that role?
patmat say @list.sort.join(', '); doesn't work 19:38
masak s1n: you're asking the wrong abstraction astronaut, sorry. :/
moritz_ s1n: I'd be very disappointed if $*IN didn't support .get
masak rakudo: say [1,2,5,4,3].sort.join(', ')
p6eval rakudo cddb16: OUTPUT«1, 2, 3, 4, 5␤»
jnthn s1n: .get would be in the Iterator role.
moritz_ patmat: what's wrong?
s1n rakudo: my @list = <hello world how are you>; say @list.sort.join(', ');
masak patmat: yes, it does.
p6eval rakudo cddb16: OUTPUT«are, hello, how, world, you␤»
jnthn For required by the iterator role...
s1n oops, well, you get the idea 19:39
jnthn *or 19:40
s1n jnthn: so there's a Iterator::get and a IO::Readable::Encoded::get? sounds like an overly bland name to choose
jnthn It may be more that Iterator just has a stub and IO::Readable::Encoded is providing the implementation.
Rakudo's IO hasn't got stuff decomposed out into all of the various roles yet, though. 19:42
Nor does it have an Iterator role.
patmat masak, moritz_ www.pastie.org/466928
moritz_ patmat: script and error message don't fit together 19:44
masak indeed.
jnthn Or if they do, something is *very* wrong...
moritz_ patmat: there's no parse error in the script you pasted
patmat sorry
found the error
jnthn has a sudden cheezburger craving
patmat i accidentely typed an "," in the @list = [] got it 19:45
s1n jnthn can haz cheesburger
jnthn I was going to make bacon sandwiches but then realized...no brown source. :-O

moritz_ FYI, I updated some of the posts on perlgeek.de/blog-en/perl-5-to-6/ (spelling, recent spec changes, rakudo improvements), and made sure that their order won't change when I touch one of the posts 19:48

moritz_ I also mailed the ironman people and asked why my blog disappeared from their blog roll

p6eval rakudo cddb16: OUTPUT«hello world␤»
s1n what's wrong with those first two snippets?
moritz_ what's the meaning of a method outside a class?
as for the second, I guess that Rakudo tries to fill the argument list for self and $what, thus expects 2 params 20:07
and you give it only one
masak moritz_: ISTR named methods outside of classes were banned at some point. 20:08
...in Rakudo.
s1n that same bit with the methods still fails within classes
masak if not, the RT ticket I submitted about it ought still be open.
moritz_ s1n: so what's the invocant of %h<foo>? 20:09
masak rakudo: class A { method foo() {}; foo }
p6eval rakudo cddb16: OUTPUT«too few arguments passed (0) - 1 params expected␤current instr.: 'parrot;A;foo' pc 113 (EVAL_21:71)␤»
moritz_ whenever you take a reference to a method you have to make clear how the invocant is passed
s1n moritz_: how do you do that?
i was trying to pass manually, but i was still having troubles 20:10
i.e. %h<foo>(self, otherparam)
moritz_ s1n: by saying -> $x { self.foo($x) } instead of &foo, for example
ie explicit currying
I don't know if there's a different solution specced for it
s1n moritz_: i don't quite get that snippet... 20:11
moritz_ s1n: the '-> $x { ... }' constructs a closure...
s1n is that how i'd put it in the hash? 20:12
moritz_ yes
s1n oh, what's the $x? the invocant?
moritz_ no, the parameter passed to .foo()
the invocant self
of course that only works inside a class

moritz_ wait a sec
let me look up the semantics of hash() first
seems to specced allright 20:20
masak sure.
moritz_: meaning... no bug?
moritz_ no, it's specced as I expected
If you wish to be less ambiguous, the C<hash> list operator will
explicitly evaluate a list and compose a hash of the returned value,
while C<sub> introduces an anonymous subroutine:

moritz_ I wonder if it should really do that (returning a list)
patmat hehe
masak moritz_: no.
moritz_: it should return a Capture.
moritz_ meh.
masak moritz_: but no-one has changed the spec yet.
patmat my girlfriend studys math and learns some Java in the university
jnthn Even in that case
patmat we learn perl6 together that makes it easier
jnthn we wouldn't be able to just do .name on it
masak patmat: sounds wonderful. 20:28
jnthn I wonder if .pick and .pick(1) should just return the item itself...
patmat: That sounds fun!
patmat yup
ab5tract it's a wild frontier.
masak jnthn: worksforme.
patmat shes unbeatable at math-examples
i'm bad at math..
jnthn masak: Maybe we should ask on p6l first.
masak: It's a discontinuity...but it might be a worthwhile one... 20:29
masak jnthn: I'm too tired right now.
moritz_ patmat: that's why she studies math, and not you ;-)
jnthn masak: Yeah same... ;-)
OK, there's tomorrow.
patmat morith_ yup that could be :D
masak jnthn: I think the Capture idea was made to reduce the discontinuity.
patmat i hope perl6 will get successful at companies for jobs
i want my helpdesk job be past!!
jnthn masak: AFAIU, a method call on a returned capture would still be a call on the capture...but maybe I don't understad the latest capture design too. :-) 20:30

moritz_ s1n: feel free to submit that as a bug... if jnthn or pmichaud disagree they'll say so on the ticket
s1n so what does everyone else far wiser than i resolve to do?
masak I believe we should adopt one or two simple principles, and run with them consistently.
those principles haven't been nailed down, however. 20:36

masak s1n: not just you.

masak s1n: I struggle with that a lot in my class design.

so we are in the same boat :)
20:38 LadyLunacy joined
masak ab5tract: indeed. except I know what's wrong with it. :) 20:39
jnthn I think the answer is "the RHS is a closure but actually wants to become an anonymous method with the current instance we're constructing passed in"
masak jnthn: .c calls the method on $_
jnthn Which may even be spec.
moritz_ jnthn: that sounds right to me
ab5tract masak, yes, you're end of the boat is fancier ;)
jnthn masak: Yeah, I was wondering if we were passing it in and it was just ending up in $_ but not self.
But apparently not.
File a ticket if there isn't one. It may be an easy fix. Especially given I gotta review all the construction stuffs anyway. 20:40
patmat LadyLunacy: \o/
s1n jnthn: on which problem? :)
LadyLunacy :P
masak LadyLunacy: welcome. I surmise you're related to patmat.

masak jnthn: I will submit tomorrow, if no-one beats me to it.
LadyLunacy thats right :D

s1n which one best describes it? this one(?): rakudo: class A { has $.a = 42; has $.b = $.a } 20:42
masak LadyLunacy: I've been thinking of how to get more women to start programming Perl 6. do you have any suggestions?
s1n shave :)
masak s1n: I think there's a bug for that one in RT.
jnthn masak: I expect next day or two I'll be doing more design work on Rakudo than code work, but hope to get the building and so on stuff beaten into a better shape into the not too distant future.
s1n: that's the one I meant, but it may already be there. 20:43
LadyLunacy masak, no idea.. all my friends hate programming :)
maybe thats because we have to learn java at university
:D
masak LadyLunacy: probably. :)
moritz_ ;-)
masak LadyLunacy: so, why don't you hate programming?
ab5tract gar, why does #parrot insist on being on a different IRC server? 20:44
s1n masak: i'll let you file the bug because i'm not sure how to explain what doesn't work :/
LadyLunacy hm i guess i like solving problems
masak s1n: I've stopped caring about explaining things long ago. I just quote from IRC. :)
s1n: what matters in a bug report is two things, basically: (1) an observable, something that you can observe being fixed (2) you're done! 20:45
moritz_ LadyLunacy: so this means we have to find more women with problems? ;-)
jnthn going to do other bits and pieces...expect I'll be around and doing Perl 6 stuff lots in the next week. :-) 20:46

moritz_ ab5tract: yes
ab5tract i hope perl6 can be different from the beginning 20:57
and i believe it can
moritz_ that would be nice

more specifically male hetronormative sexual imagery
as the presentation was biased that way 21:00
ANYHOW
moritz_ kane__: I very much enjoyed watching it on yapc.tv ;-)

thats it to show an int???
looks a bit terrible
moritz_ not quite, because .lines returns a list 21:36
so that will give you always 1
yes, it's terrible
patmat so how is the simplest way to make the .get function for .int ?
moritz_ my $s = $*IN.get; my Int $i = $x.int; is better
rakudo: say (~$*IN.get).int
p6eval rakudo cddb16: OUTPUT«0␤» 21:37

why the hell is it 2? :D
it looks like the interpreter ignores everything :P
moritz_ wait a sec, I have to recompile rakudo 21:45
patmat okay, why? :P
moritz_ I had local changes
that screwed it all up

too late to detect jokes
patmat :/
moritz_ so $zufallszahl is 65, but $zufallszahl+1 is 2? 21:48
ah 21:49
patmat haha yes
moritz_ as masak said earlier, (1..100).pick returns a list
of one element
when you print it, you simply see the element 21:50
when you use it as a number, it does arithmetic with the number of arguments
21:50 kirillm__ is now known as kirillm
moritz_ when you do a 'say $zufallszahl.perl' you'll see what I mean 21:50
$thing.perl gives you a short Perl program that evaluates back to $thing 21:51
