au quietfanatic: one good place to start is github.com/perl6/Pugs.hs/blob/master/HACKING 05:10
the entire paragraph about 7.2.1 is perhaps no longer current
and please feel free to excise it and/or update it with your current/recent experience installing GHC on (presumably) an debian/ubuntu system 05:11
quietfanatic Cool, I'll get on that, next tuit I have.
I had a commit bit to the original pugs repo (for tweaking the website stuff), but I don't think I have one to this one. 05:12

GlitchMr Should Perl 6 installation return lots of gcc warnings? 07:58
(rakudo)
07:59 Bzek left
moritz depends on what you mean by "should" 08:06
I'd certainly prefer a cleaner build
and would accept patches that clean up the warnings
GlitchMr Fixing things like multidispatch.c:671:21: warning: suggest parentheses around ‘&&’ within ‘||’ [-Wparentheses] would be easy, at least I think so 08:07
sorear I think that's a ridiculous warning 08:08
GlitchMr But well, everybody knows that a && b || c && d is (a && b) || (c && d)
diakopter people forget 08:09
moritz I think we should compiler without -Wparentheses
GlitchMr glitchmr@strawberry:~/git/panda$ ../../rakudo/bin/perl6 bootstrap.pl
sh: 1: perl6: not found
fun
diakopter people work when extremely tired. people get older. people confuse themselves. "everybody knows" isn't true for every coder all the time. 08:10
moritz GlitchMr: panda expects a perl6 binary in $PATH
GlitchMr why?
It doesn't make sense to depend on this 08:11
moritz GlitchMr: because it's easier that way, and nobody has taught it to do otherwise
GlitchMr: I'm pretty sure tadzik++ would accept patches
GlitchMr shell "perl6 bin/panda install File::Tools JSON::Tiny Test::Mock"; 08:12
Yeah..
moritz yeah!
GlitchMr What if my interpreter is "rakudo" or something
moritz then your patches are very welcome 08:13
GlitchMr Also, just wondering, but does shell support multiple arguments just like system in Perl 5? 08:14

hello sergot
mucker hi guys. is there an easy way to download the spec tests ?? 08:29
tadzik yes 08:31

mucker thnkx ! 08:32
tadzik or from github.com/perl6/roast/downloads
you're welcome
mucker one thing I have always like about perl* is, tests are like extra documentation :) 08:33

Should it be this way? 08:39
moritz GlitchMr: github.com/tadzik/panda/issues/4 08:41
tadzik yeah
maybe I should just remove that test 08:42
GlitchMr I guess that rakudo doesn't support "is export" 08:45
moritz GlitchMr: don't guess 08:46
tadzik it does
GlitchMr ===SORRY!===
Missing block
at Addslashes.pm:2
Weird...
moritz then you did something wrong.
GlitchMr This is what I get for not testing code at all
This is my code: github.com/GlitchMr/perl6-Acme-Add...slashes.pm 08:47
moritz the traits come after the signature
GlitchMr Oh, ok
I guess that "no ICU lib loaded" is connected to "\c[COMBINING LONG SOLIDUS OVERLAY]" 08:48
Is it possible to install ICU lib? Or should I just use normal \x escapes
moritz if it weren't possible to install ICU lib, we wouldn't rely on it. 08:49
GlitchMr How can I install it? I'm at Kubuntu machine 08:50
moritz please see rakudo's README or INSTALL files
GlitchMr ok
08:51 prettyrobots left
GlitchMr That's 10MB, but I guess that ICU contains Unicode database and things like it, so ok 08:51
I guess I have to compile rakudo again?
moritz I guess you even have to reconfigure and recompile parrot 08:52

#?rakudo 3 skip '$/ not involved in .subst yet (unspecced?)'

masak aye, mid-antenoon. :) 09:31
diakopter whines at this 1220-line C file that is segfaulting.
moritz valgrind! valgrind!
GlitchMr Just wondering, why $/ isn't @/? 09:33
diakopter I know exactly where the problem is; I just can't see what I'm doing wrong; the pointer arithmetic looks right to me.
GlitchMr Oh, right... I just noticed it mixes hash and array
au because of named captures? 09:34
moritz let's name it $@%/, because it has aspects of a scalar, an array and a hash 09:35
GlitchMr ok, I guess that $/ is better then 09:36
Timbus now you're just swearing
masak .oO( too bad Match isn't Callable, too... )
GlitchMr $@%&/ would be nice
moritz masak: I'm sure we can find a meaning for that too :-) 09:37
GlitchMr Heh, I find it interesting that official JavaScript implementation once had callable regexpes 09:38
Because it was callable, it has to return "function" on typeof
After some time, they got bug report about regexpes being "function"s.
Fix: Make typeof return "object" for RegExp as special case
Good thing that today RegExpes aren't callable at all 09:39

Just wondering, why parenthesis are required when calling method with any arguments 09:48
Ruby is happy without parenthesis 09:49
moritz because it makes argumentless method calls more convenient
GlitchMr What's wrong with making $a.b.c mean what it means actually and $a.b .c mean $a.b($_.c) 09:50
moritz predictive parsing 09:51
tadzik people are upset already about whitespace sensitivity
moritz if you allow $a.b 'c' to mean $a.b('c'), it means you expect a term (and not an operator) after $a.b 09:52
which means that you can't write $c.re + $c.im anymore
GlitchMr Hmmm... yeah
moritz and other very neat stuff stops working too
GlitchMr re($c) + im $c
Well, whatever, it's not like you commonly call methods with arguments 09:53
Timbus "a -1; a=0; a -1" parses as "a(-1); a=0; a.+(-1)" in ruby. im just saying 09:54
moritz yes, argumentless method calls are much more common
everything that looks like an attribute access ($.foo)
is actually a method call with an argument 09:55
masak <moritz> if you allow $a.b 'c' to mean $a.b('c'), it means you expect a term (and not an operator) after $a.b 09:56
best and shortest explanation of that I've seen to date.
moritz++
moritz bows
GlitchMr Timbus: O_o 09:57
masak somethings about it bugs me, though.
GlitchMr I through that Ruby grammar uses whitespace for that
masak how come Java doesn't run into this problem?
moritz masak: does Java do predictive parsing at all?
masak in Java, you can do object.foo␤.bar
moritz: no, and that's probably it. 09:58
moritz does java allow .bar without a preceeding term?
masak if by that you mean "zero-lookahead", fsvo "zero".
moritz: oh! no, it doesn't. :)
GlitchMr Ok, Ruby does that, but I'm sure that coffeescript.org/ doesn't do that
moritz masak: with predictive parsing I mean that the grammar can disambiguate the same symbol used in term and in infix position 09:59
masak .oO( of course not, it's a website! ) :P
moritz GlitchMr: are you aware of the colon syntax for passing arguments to methods?
GlitchMr Yes
masak moritz: I'm not sure I feel the term is that obvious. "predivtive" sounds like "makes a lot of clever guesses" to me. 10:00
GlitchMr But I don't think that I can earn anything with colon
masak "earn"?
tadzik it looks good
moritz masak: I never said it's obvious :-)
masak you can put arguments there without parens! :)
GlitchMr What "$a.method: 2" gives me compared to "$a.method(2)"
moritz no parens
GlitchMr But I have colon
masak indeed you do.
moritz avoiding parens is what we talk about all this time, no?
GlitchMr Well, I also could call eval() with cleverly hidden parenthesis but that isn't the point 10:01
tadzik you don't save bytes this way, no
GlitchMr I meant, eval
After all I want to avoid parenthesis
moritz then use the colon :-) 10:02
masak at least one of us is being difficult in this conversation.
what are we trying to achieve?
are we doing language design (proposing to allow method calls with args but no colon or parens), or talking programming esthetics (it looks so much nicer when I don't have to use parens, but the colon is ugly, too!)? 10:03
GlitchMr Actually, I think that colon is good enough 10:04

It probably needs less RAM to build than CORE.setting for one. 16:54
benabik -G?
jnthn And it means some people who can't build otherwise would be able to.
But yes, it's hiding the real problem.

p6eval rakudo cfe8e5: OUTPUT«max13fr has 2 digits in it.␤»
masak max13fr: now for the real answer.
max13fr :)
masak max13fr: we already have quite a lot of features. see perl6.org/compilers/features for just how many.
we're now working on making things faster, more user-friendly, better documented, and more welcoming. 17:17
the point where you will start to call things "stable" depends a bit on who you are.
max13fr so for a professional use, you think it's better to use perl5 or perl6
masak are you an early adopter? can you withstand certain amounts of pain? what are your criteria for 'production use'? and so on.
max13fr: if you're asking that question, probably yes.
but with that said, I've been using Perl 6 in production situations for two years now. 17:18
thou [Coke]: you wrote "moritz++ - hey, now I get gather/take." — what were you referring to (i'd like to read up on it if there's a pointer to something enlightening)? 17:19
max13fr if I understand, for little script perl6 it's ok 17:20
but some fonctions have still buggued
diakopter depends what you want the littlte script to do.
max13fr for example backup bdd 17:21
generate rrdgraph
masak oh, I assure you there are bugs.
but nowadays they're not so easy to find anymore...
diakopter max13fr: those would be good exercises to try. niecza is probably better at heavy data processing since the GC is more reliable.. 17:23

mathw ah, I don't have a full understanding of protos
masak mathw: $ vs \$
jnthn $ vs |$
masak oh!
mathw i don't actually know what the \$ in the multis does
jnthn The proto inliner clearly isn't strict enough.
It is fine to inline a proto that is going to bind whatever then delegate. 20:33
But that isn't the case with a proto that needs to enforce "just one arg"
With the optimizer gone, we actually call the proto.
And the default argument type is Any. 20:34

timotimo so i'm definitely not doing it right
masak any occurrence of 'ListIter.new()' in .perl output is to be considered a bug. 23:51
anyway. 'night, #perl6
timotimo good night masak 23:52
how *can* i gather a list of lists together? 23:54
r: say gather for ^5 { take 1 xx $_ } 23:55
p6eval rakudo 4eeffc: OUTPUT«1 1 1 1 1 1 1 1 1 1␤»
timotimo r: say gather for ^5 { take $_ xx $_ }
p6eval rakudo 4eeffc: OUTPUT«1 2 2 3 3 3 4 4 4 4␤»
timotimo r: say (gather for ^5 { take $_ xx $_ }).perl
p6eval rakudo 4eeffc: OUTPUT«(1, 2, 2, 3, 3, 3, 4, 4, 4, 4).list␤»
timotimo r: say (gather for ^5 { take [$_ xx $_] }).lol.perl
p6eval rakudo 4eeffc: OUTPUT«LoL.new(ListIter.new())␤»
timotimo r: say +(gather for ^5 { take [$_ xx $_] })
p6eval rakudo 4eeffc: OUTPUT«5␤»
timotimo that seems right 23:56
r: say (gather for ^5 { take [$_ xx $_] }).lol[0]
p6eval rakudo 4eeffc: OUTPUT«ListIter.new()␤»
timotimo r: say (gather for ^5 { take [$_ xx $_] }).lol[0].flat
p6eval rakudo 4eeffc: OUTPUT« 1 2 2 3 3 3 4 4 4 4␤»
timotimo :\
23:56 gtmantred is now known as sudokode
Tene timotimo: that looks right to me... 23:57
what's your desired output?
r: say (gather for ^5 { take [$_ xx $_] }).gist
p6eval rakudo 4eeffc: OUTPUT« 1 2 2 3 3 3 4 4 4 4␤»
Tene r: say (gather for ^5 { take [$_ xx $_] }).perl
p6eval rakudo 4eeffc: OUTPUT«([], [1], [2, 2], [3, 3, 3], [4, 4, 4, 4]).list␤»
23:57 quietfanatic joined
timotimo r: say (gather for ^5 { take [$_ xx $_] })[0].perl 23:58
p6eval rakudo 4eeffc: OUTPUT«[]␤»
timotimo mhm. wonder what i did wrong :)
Tene You did something wrong?
quietfanatic ^5 is 0..4
0 xx 0 is [] 23:59
Excuse me, [0 xx 0] is []
