quietfanatic oh it does work
which means rule subcalls are lexical, which means you don't need a grammar 00:59
which will make implementing <foo>-type subrules in formats so much easier.

diakopter why don't they?
quietfanatic right
01:11 tokuhiro_ left
quietfanatic they don't match it because it infinitely recurses, requiring one more 'a' each iteration. 01:11

also shouldn't mine ltm?

hm. the next morning, $dt.ymd and $dt.hms still feels like an OK idea. 06:47
it's just a shorthand for a common type of formatting.
quietfanatic good morning masak 06:48
diakopter masak: ymd
er. 06:49
I'm not sure what I meant to say there. it's late.
masak :D
well, 'ymd' is the ISO way.
quietfanatic good ymd, masak
masak I think we should only have 'hms', but for the 'ymd' permutations we might go with all the ones CPAN's DateTime has.
quietfanatic actually that should be hms, huh 06:50
masak quietfanatic: it's a good ymd indeed, quietfanatic. first day of YAPC::Europe.
quietfanatic ooh, nice
masak .oO( no, Frankfurt ) :P
quietfanatic good hms, happy ymd 06:51
masak .oO( Nice is the other way )
quietfanatic there we go :)
I...see.

masak I found gist.github.com/355605 in the IRC logs. 07:01
.ymd and .hms aren't in there.
that makes it easier to think that it might have been just an omission. 07:02
masak is kinda glad we didn't end up with "hextime" in the Temporal spec: github.com/perl6/specs/commit/fd5d...96a#L0R151 07:06

masak well, it was good that that version got pushed, I think. for me, it was a wake-up call; the Temporal spec could be changed from something bad to something even worse. but it could also be improved through focused effort. 07:15
I think the current spec has stood the test of time. 07:16
well, apart from the parts that have drastically changed, of course ;)
but the original intent is still there: a simple, sane, subset of CPAN's DateTime.

tadzik jnthn++ has presented a Perl 6 debugger in his talks 13:25
13:25 drbean left
tadzik about 700 lines of awesome, and makes Perl 6 jealoius 13:25
erm Perl 5 jealous that is
colomon Perl 6 debugger?! 13:26
tadzik yeah
it totally kicks ass
colomon jnthn++
is it on github yet? ;)
tadzik Perl 5 folks were like "I CAN HAS?"
nope, will be 13:27
pmichaud jnthn++ promises to push the debugger soon
hoelzro what's so cool about this debugger?
pmichaud we expect to include it in the 2012.08 R* release
it's interactive
it's like tracing code from the REPL
tadzik it has colours
pmichaud it comes with batteries
moritz hoelzro: we didn't have a debugger before
\o/ jnthn++
moritz wonders how exactly it relates to the "exceptions" topic 13:28
hoelzro moritz: well, that's a definite advantage =)
I guess what I mean to ask is what makes it superior to Perl 5's debugger =)
pmichaud moritz: he was able to use the debugger to introspect the exceptions at the point they were thrown
tadzik it helps you debug when you have an exception, obviously :)
pmichaud i.e., in the debugger one can say "run until breakpoint or exception"
tadzik hoelzro: the awesome
13:28 skids joined
pmichaud when an exception is thrown, the debugger takes over, displays where you are, and you can introspect the exception and other things at the point of the throw 13:29
hoelzro pmichaud: I'm guessing you can filter on exception type?
pmichaud hoelzro: I don't know about that.
I suspect that might be possible.
moritz probably just a SMOP :-)
hoelzro or even a generic predicate? ex. break exception { $^ex.can('method') }
moritz that's basically just a type 13:30
pmichaud the code is only ~800 lines of NQP+Perl 6 code, so it should be very very hackable
moritz subset CanMethod of Any where .can('method');
gfldex so i could see not only what exception was thrown where, but also the state (and therefore variables) at the point where it was thrown?
pmichaud gfldex: yes, that's what it looked like
moritz wants to see the code
gfldex do want!
i found it always a little silly to have a stacktrace but not the parameters of the top function in that trace 13:31
you can get that with setting breakpoints, but you have to run the program twice for that
moritz well, there's always the question on how to represent objects
you don't want a .perl output that spans 50 screen pages in a backtrace 13:32
[Coke] eager awaits the commit. jnthn++ 13:33
*eagerly
pmichaud it's a separate module, atm
at least I understand it to be that way 13:34
hoelzro I think it'd be cool if you could write debugging profiles as roles
pmichaud twitter.com/pmichaud/status/237542903138881536
hoelzro so do something like \load Profile.pm6
which would contain a role that would be applied to the debugger object, so you can automatically set breakpoints and such
[Coke] has an idea for a bot! 13:37
[Coke] has a $DAYJOB. dammit!
Do we have any existing written-in-perl6 irc bots? 13:38
13:38 drbean joined
hoelzro I have a Perl6 XMPP bot 13:38
(which is unfinished)
which reminds me...I should really try to fix that bug that's blocking my bot for the next R* 13:40

hoelzro well, I'm not going to make it =P
[Coke] wonders if JSON::RPC::Client can be told to follow 3xx responses. 13:44
can we invoke methods with "." 13:46
er... with "." in the method name?
13:47 fridim_ joined
flussence after trying to sift through >1MB of dump output full of DBIC at $dayjob for the millionth time, I'm thinking a hidden_from_{gist,perl} like the hidden_from_backtrace trait we've got might be useful at some point 13:48

there's a fork of modules.perl6.org that has readmes included and other stuff
13:54 MayDaniel joined
sirrobert I would love to see user tagging (always wanted that for the CPAN). 13:54
tadzik so arbitrary users can tag modules?
sirrobert to allow a soft tie between modules that play well together
in a sort of stackoverflow way
tadzik: yeah 13:55
hoelzro so someone (I think jnthn) recommended I use nqp::findmethod($!pun, $name)($inv, |@pos, |%named) to fix qualified method calls to a method in a Role. I tried this, but it doesn't seem to work (type check failure). Any recommendations on how to fix qualified method calls?
sirrobert like... adding a module to a collection (tag) or something
hoelzro s/$/ with roles/
tadzik sirrobert: could you open an issue on github.com/sergot/modules.perl6.org ?
sirrobert tadzik: sure
tadzik: I don't seem to be able to access the issues section 13:57

japhb tadzik, I have to change bootstrap.pl at least a little to fix the "DESTDIR shouldn't go into a subdir of cwd" problem -- the first of my questions comes down to "fix or delete". The second question (re: external PERL6LIB) we can table, no problem. 14:15

tadzik okay, I suspect that the whole DESTDIR case is just me being stupid in the first place 14:17
so you may want to try removing that {cwd}/DESTDIR thing and seeing if that works 14:18
if it doesn't then I think it's better to remove it instead of having it wrong, I can try to recreate that later on

[Coke] so, if I have several local installs of rakudo, can I use panda in each of them, or is panda tied to my home dir? 14:53
moritz [Coke]: currently it's tied to the home dir :-)
erm, :-(
that annoys me as well
flussence
.oO( you could always use multiple home dirs... )
 14:54
PerlJam wonders if it's worth it to have perlbrew-like functionality built-in to perl 6
[Coke] so, if I use panda, I should have a separate dir I work in panda out of, and not try to use the various rakudo build dirs.
moritz what I sometimes do is cp -r ~/.perl6/lib/* `perl6 -e 'say @*INC[1]` 14:55

[Coke]: correct
[Coke] no need shouldn't == "BOOM"
if I run ".../path/to/star/panda help" it dies with the same Shell::Command error. 15:00
that is: ~/sandbox/cjsix/rakudo-star-2012.07/install/bin/panda help

tadzik: gist.github.com/3405487
now, I did try to run bootstrap at some point. Could that have sabotaged a working panda? 16:24
hurm. I can always reinstall and check, I suppose.
moritz something is odd with that installation 16:25
the install location is ./rakudo-star-2012.07/install
but it has /home/ingy/local/lib/parrot/2.7.0/languages/perl6/lib in @*INC
[Coke] arrrgh.
I just cd'd to rakudo-star-2012.07, rm -rf install, make install... "nqp is too old" 16:26
moritz: I just did "perl Configure.pl --gen-parrot; make; make install" in that dir.
bah. I'll remove the whole build and try again.
moritz hm, maybe some part of the star installation uses the perl6 from $PATH, not the right one 16:27

colomon 's interaction in this issue is not helped by the fact that none of his software displays that digit as anything but a box.
moritz you "just" need a hash with all digit characters and their integer values 17:32

all? 17:50
colomon there's no clue in the Numeric values file that it might be anything other than base 10
colomon loves the fact that half zero is -0.5 17:51
diakopter do you see the pattern?
[Coke] was reading those "halfs" kind of like "quarter to" on a clock. 17:52
colomon to the tibetan half digits? it's minus .5 from the normal digits
moritz sirrobert: I guess I should write an FAQ entry about that
sirrobert =) 17:53
colomon it seems like niecza isn't handling the Numeric_Value table properly (or I just haven't figure out how to use it), so adding other digits will not be trivial.

$inv is a Consumer object, which consumes R
19:18 jeffreykegler left
hoelzro self is expected to be something that consumes R 19:18
moritz so, pure speculation 19:19
R is generic in its invocant type
so the R composed into Consumer is really R[Consumer]
and R[Consumer] doesn't typecheck against R 19:20
hoelzro that sounds about right.
it seems that the Rakudo C stuff doesn't check roles when typechecking

hoelzro huh.
moritz that's a type check against a role
hoelzro wonders why he can't find a single reference to roles in src/*/*.c
moritz nr: role R { method me() { } }; class Consumer does R { }; say Consumer ~~ R 19:22

hoelzro the failure I'm seeing is happening with qualified method calls 19:27
and I'm not sure how to check role consumption from C... 19:28
moritz I guess that's what the STABLE(...)->type_check does 19:30
hoelzro yeah, that's what I would think
although it doesn't seem to work 19:31
I'll try some other stuff out...
19:33 SamuraiJack_ left 19:37 DreamingInCode joined 19:45 erkan left
hoelzro ok 19:50
here's the deal
$inv.does($obj), but $inv doesn't have a relationship to the pun object
so Rakudo tries to typecheck Consumer against Any+{R}, which fails
19:53 att left
arnsholt IIRC there're some issues with roles in Rakudo. It's a problem for Zavolaj as well 19:59
Could be something related to parametrized roles if your code above is representative 20:00
hoelzro my test doesn't use parameterized roles at all
is there a way to get the code for a Role's method other than nqp::findmethod? 20:08
20:14 nich0s joined, stopbit joined, nich0s left
moritz sure 20:21
YourRole.^find_method
hoelzro that's implemented via RolePunning, right? 20:22
moritz you can also look into the various files in src/Perl6/Metamodel/ and see if you find some low level access 20:25

sirrobert r: class A is Array { has $.str = "foo"; }; say A.new.str; 20:33
p6eval rakudo 009325: OUTPUT«Any()␤»
sirrobert That seems to work if I do something like "does Positional", but then I don't get Iterable 20:35
any tips for making an array-like thing?
moritz is that related to Array.new doing funky stuff? 20:36
sirrobert hmmm dunno
how could I check?
moritz r: class A is Array { has $.str = "foo"; submethod BUILD(:$!str) {} }; say A.new.str 20:37
p6eval rakudo 009325: OUTPUT«Any()␤»
moritz sirrobert: see what List.new and Array.new do
sirrobert ok, one sec
moritz maybe it doesn't go through bless
hoelzro wishes the build cycle for Rakudo were a little shorter...
sirrobert yeah, array has its own new method... it doesn't seem to use bless, but I don't know what it does do =) 20:39
some nqp and pir stuff
pmichaud good evening, #perl6
hoelzro o/ pmichaud
sirrobert hi pmichaud
moritz: same with List
20:40 skids left
moritz sirrobert: it's bless that is (indirectly) responsible for attribute initialization 20:40
pmichaud I might be able to get List.new and Array.new to go through bless.
sirrobert out of curiosity, why wouldn't they go through bless? 20:41
pmichaud speed
sirrobert ah
I'm trying to make an List-like thing
pmichaud lists are fundamental and used by a lot of internals; you don't always want things going through the extra work of bless and the BUILDALL sequence
sirrobert yeah
moritz r: class A is Array { has $.str = "foo"; method new(*@elems, *%attrs) { my $cand = self.Array::new(@elems); self.bless($cand, |%attrs) } }; say A.new.str
p6eval rakudo 009325: OUTPUT«foo␤» 20:42
moritz sirrobert: that should fix it
sirrobert moritz++
thanks
moritz r: class A is Array { has $.str = "foo"; method new(*@elems, *%attrs) { my $cand = self.Array::new(@elems); self.bless($cand, |%attrs) } }; say A.new(<a b c>)[1]
p6eval rakudo 009325: OUTPUT«b␤»
pmichaud the internals don't use .new very much, though, so it wouldn't surprise me if I could refactor (Array|List).new to use BUILD and work with bless
moritz that's the first time that the candidate argument to bless is actually useful 20:43
I mean, that I find it useful for stuff

21:10 kaare_ left, fibo left 21:11 MayDaniel left
jnthn hoelzro: oh, I see you asked something about how role type checking works 21:13
The answer is that the ->type_check stuff is implemented in the 6model core 21:14
(thus in the nqp repo)
but the interesting logic of what types are accepted is held completely in src/Perl6/Metamodel
hoelzro yeah, I've spent the last couple of hours wrapping my head around both of those =) 21:16
jnthn :)
hoelzro but at least now I have a (slightly) better idea of how Rakudo works
which will make future work easier =)
