araujo Juerd, yes 00:11
TreyHarris araujo: memory helps a *lot*. i went from 512 to a gig and compile time dropped by half 00:16
but it still takes 35 or 45 minutes on my PPC 1.5 00:17
araujo yeah, more memory will do it 00:24
00:39 zgh joined 01:06 markstos_ joined
araujo hi markstos_ 01:07
markstos_ hello araujo
araujo markstos_, just read perl6 will have function currying :-)
that is another very haskellish feature , which i am happy to see here 01:08
markstos_ araujo: Where can I read more about how this will look and work in Perl6? 01:09
araujo markstos_, oh, i just read it as a new feature listed on the faqs of perl6 ... i still dont find any further explanation 01:10
svnbot6 r12749 | markstos++ | CGI.pm: Use method, not submethod, because we do what these behaviors to be inherited.
r12750 | markstos++ | ChangeLog updates
araujo i would like to, so, if anyone knows....
markstos_ Let me grep the specification..

markstos_ feather.perl6.nl/syn/S06.html#Currying 01:12
lambdabot Title: S06
markstos_ Jes. Just found it.
s/Jes/Yes.
araujo cool 01:17

markstos_ I'm getting started on feather and syntax highlighting isn't working for me. I get an error on line 42 of syntax/syntax.vim: E216: No such group or event: filetypedetect BufRead 01:43
That familiar to anyone ?
I tried copying audrey's syntax/syntax.vim to my ~/.vim, but that didn't help.
I also tried removing my own .vimrc, but I still get the issue, indicating some kind of system level problem. 01:45
markstos_ ponders this
Here's a bug report and fix for the issue. Perhaps it's related to the OS upgrade earlier today: 01:48

I just did a file transfer of a 10GB file.... 01:57
which took a long time
the transfer stalled with a few MBs to go
seriaously 99.999
so what transfer util will recover from where I left off? 01:58
obra rsync may
ingy hi obra
I hate mac so much I just went out and ought a new macbook to teach em a lesson 02:00
I think I'll be integrating libyaml into the new YAML.pm 02:02
it looks ready
also thinking about a javascript port... 02:03
obra cool. How does libyaml differ from libsyck? 02:04
02:04 theorbtwo joined
ingy obra: it's a streaming API 02:07
it's built the way that yaml tools were indented to be built 02:08
;)
libyaml - data the way that ingy indented it 02:09
the other difference is that it probably is much closer to spec correct, and has much better error reporting (I'm guessing) 02:10
libsyck is some whimsical approximation of YAML 1.0 02:11
obra cool. 02:12
02:12 cognominal joined
obra streaming yaml would be very interesting 02:12
ingy well it's not just for streaming 02:13
it's just that the low level (read hard) stuff is streaming

markstos_ Why doesn't this work as expected? 02:33
?eval sub foo(%h) { say %h.perl } foo(1=>2,2=>3)'
evalbot_12750 Error: unexpected "'" expecting ":", term postfix, comment, operator, postfix conditional, postfix loop, postfix iteration, ";" or end of input
markstos_ ?eval sub foo(%h) { say %h.perl } foo(1=>2,2=>3)
evalbot_12750 Error: No compatible subroutine found: "&foo"
ayrnieu ?eval sub foo(%h) { say %h.perl }; foo(1=>2,2=>3) 02:34
evalbot_12750 Error: No compatible subroutine found: "&foo"
TreyHarris ?sub foo(Pair $h, Pair $y) { say ($h, $y).perl }; foo(1=>2,2=>3) 02:36
lambdabot Parse error
TreyHarris ?eval sub foo(Pair $h, Pair $y) { say ($h, $y).perl }; foo(1=>2,2=>3)
evalbot_12750 OUTPUT[((1 => 2), (2 => 3)) ] Bool::True
markstos_ It works if I define 1=>2,2=>3 as a hash explicitly has a hash beforehand, and pass the hash in.
TreyHarris you're not passing in a hash
you're passing in two pairs
markstos_ But that's the typical way to pass in named arguments, right? 02:37
Should I be defining each known key of the hash in the subroutine sig ?
TreyHarris you have two problems
one, you have to make your hash slurpy: 02:38
?eval sub foo(*%hash) { say %hash.perl }; foo(1=>2,2=>3)
evalbot_12750 OUTPUT[{} ] Bool::True
markstos_ thinks he has 2 problems, plus the barking dog across the street that won't shut up.
TreyHarris but that still doesn't work
because pairs of random data can't possibly be named args
markstos_ I tried the slurpy. That didn't work.
TreyHarris they have to be identifiers:
?eval sub foo(*%hash) { say %hash.perl }; foo(a=>2,b=>3)
evalbot_12750 OUTPUT[{("a" => 2), ("b" => 3)} ] Bool::True
TreyHarris there.
markstos_ What's the difference between that and the version above? you changed the key names? 02:39
TreyHarris yes
'1' and '2' aren't valid identifiers 02:40
markstos_ why would that make a difference?
Ah.
TreyHarris named params must be idents
markstos_ idents?
TreyHarris identifiers
markstos_ Anyway, my keys in my applications don't need to be numbers.
ayrnieu ?eval [1=>2, '1'=>2] 02:41
evalbot_12750 [(1 => 2), ("1" => 2)]
TreyHarris ?eval %(1=>2, '1'=>3) 02:42
evalbot_12750 {("1" => 3),}
ayrnieu that's not actually intended, is it? 02:43
TreyHarris that's correct behavior 02:44
of a default hash
because 1 and '1' are the same hash keys
zgh i though hashes in perl6 dodn't automatically stringify the keys
ayrnieu ?eval %(1=>2, '2'=>3) 02:45
zgh s/dodn't/didn't/
evalbot_12750 {("1" => 2), ("2" => 3)}
zgh that's kind of disappointing
where are the key-type-agnostic hashes in perl6
TreyHarris zgh: they do currently in pugs. let me consult the synopses, but i'd expect that to be the default behavior, it would be extraordinarily surprising to perl 5 programmers. 02:46
i believe that .SKID controls (but .SKID is currently unimplemented)
ayrnieu a perl5 programmer would expect scalars, yes.
02:47 mako132_ joined
TreyHarris markstos_: to continue what i was saying first: 02:47
?eval sub foo($a?, *%hash) { say %hash.perl }; foo(a=>2,b=>3)
evalbot_12750 OUTPUT[{("b" => 3),} ] Bool::True
zgh i'm a perl5 programmer, but i have used languages where hash keys were immutable objects or whtever instead of hashes
it's not THAT surprising
ayrnieu zgh - yes, yes, but a perl5 programmer would expect scalars to act like scalars. 02:48
zgh instead of hashes?
i meant instead of strings sorry lol
well numbers are scalars
(some) objects are, yes
TreyHarris notice the first key was not output, because it was bound to $a. slurpy hashes are meant to grab all named parameters, so only parameters that could be otherwise named are grabbed
zgh ?
i can't say i ever found perl5 hashes lacking...i think the theorist in me likes having whatver types I want in a key 02:49
ayrnieu zgh - as long as one of those types is 'scalar', everyone is happy. 02:50
zgh ayrnieu: how very true!
TreyHarris zgh: according to S09, you write "my %hash{*}" to indicate that you want to accept keys of any type 02:53
otherwise they are strings
this is not yet implemented.
zgh TreyHarris: hey cool! thanks for looking that up. 02:54
TreyHarris the default hash is "my Any %hash{Str}"
zgh TreyHarris: okay that makes a lot of sense.
not at all surprising to a perl5 programmer while still thrilling the theorists. yay! 02:55
TreyHarris yes-- TimToady++ is very good at doing that
kind of like how the issue of whether failing subs should throw exceptions or return undef was resolved 02:56
they return undefs that autothrow exceptions if you try to use them for any other than testing for truth or definedness 02:57
so you can still do if thingThatMightThrow() -> $x { $x.useIt() } 02:58

pasteling "markstos_" at 12.176.101.89 pasted "bug? multi-dispatch works differently for subs and methods when passing a scalar when a slurpy has is expected" (31 lines, 511B) at sial.org/pbot/19291 03:33
markstos_ The method dispatching in that paste seems wrong. Even though I call foo(1), I get dispatched to foo (), which explicitly says it has no arguments. (How do I check the arguments when the signature says they are none?) 03:34
TreyHarris heh, it just segfaults me :-) 03:35
markstos_ Doh.
TreyHarris the sub gets "in hash sub but not a hash", and the method gets "none"? 03:36
markstos_ Yep.
TreyHarris oh
yes
markstos_ yes, bug?
TreyHarris that's correct, though admittedly surprising
markstos_ sighs.
TreyHarris remember, like in perl 5, methods are subs with an extra argument for the invocant
markstos_ Ok. 03:37
TreyHarris MMD will never dispatch to a nonconformant subroutine.
so it tries to figure out what's most conformant
yes, it *is* a bug now that i think about it
but it's trying to do the right thing
markstos_ That makes more sense.
..that it's a bug.
How would I examine the args in method foo (), since they aren't in the signature ? 03:38
03:39 zgh joined
TreyHarris in the first you have the signature (Foo:), and in the second, (Foo: Any Hash{*}). you called it with (Foo: Int). it should have failed, but instead it dispatched the first. the second time you had signatures () and (Any Hash{*}), and you tried to pass (Int). it should have failed as well. 03:40
i think it has something to do with this:
?eval multi sub foo ($a) { say "yep" }; foo(3)
evalbot_12750 OUTPUT[yep ] Bool::True
TreyHarris ?eval multi sub foo () { say "yep" }; foo(3) 03:41
evalbot_12750 Error: No compatible subroutine found: "&foo"
markstos_ Those results look reasonable.
TreyHarris guess it was fixed since i last tried it :-) 03:42
hm
markstos_ It's the method case that seems b0rked.
TreyHarris well, they're both borked because it's not reasonable to set a hash to the value 1
markstos_ In may case, I think I think I'll leave that test failing in the CGI::App suite, and note that I think it's due to a pugs bug.
TreyHarris but even if it's just doing mmd by arg counting, yes, it's borked 03:43
03:44 zgh joined
markstos_ All I wanted to do was die with an nice error about using the wrong number of args, but I can't do that, because it it's dispatched to foo(), where I don't know how to examine the args, since they aren't in the signature.... 03:44
TreyHarris introspection is very lacking at present.
audreyt keeps saying that's her first priority after captures and the object model
markstos_ So far I haven't run into a show stopper for my own work, just some mysterious detours... 03:45
TreyHarris sighs 03:46
I've let my pugs get almost a week out of date
and I wanted to write a little explorer to help me look at changes in an easier format than raw svn commands
but pugs is segfaulting or giving me "illegal hardware instruction" in my explorer
markstos_ Ug. 03:47
TreyHarris well, it won't be too hard to quickly translate to perl 5 03:48

ayrnieu (hey, neat, that Chinese actually displays here.) 05:39
xinming ayrnieu: we use utf-8, so, displaying multi-byte characters should be no problem. 05:40
ayrnieu: and BTW, in perl6, there would be a native language dialect probably... :-) 05:41
ayrnieu: which means, we can write perl 6 in our own language.. :-P
audreyt what, you mean Perl is not your native language? 05:45
:)
kasei: sorry, still installing PCR dependencies on this win32
kasei no worries. thanks for taking the time. 05:47
xinming audreyt: No, I mean, we can write a perl 6 dialect which replaces sub and say with native language keywords, I've ever found an interesting program which is written in Chinese in perl 5 from you. :-) 05:49
audreyt er, yeah, that must be Lingua::Sinica::PerlYuYan
btw, r12752 is for you :)
xinming thanks 05:50

audreyt kasei: the moose moosed because <uchar>* assumes <ws> between each <uchar> 05:51
I'm not sure if that should be the case, actually
but it is currently the case. 05:52
so if you change Rule->install to Regex->install
(also, you can put <?uchar> instead of <uchar>)
since you are capturing the outer sum anyway
then it'd work. 05:53
xinming How can I see the difference you edit in src? I mean with your last commit...
kasei audreyt: thanks! 05:54
xinming hmm, Ok, I'll try myself. :-/

Juerd :)
markstos++ # told me how
markstos_ Interwebthingie++ had the answer
This is unexpected. If I quote my key, the args disappear. If I leave the key bare, they work: 12:53
?eval sub foo (*%args) { warn %args.perl; } foo( a => 'b' ); foo( 'a' => 'b' );
evalbot_12761 Error: Cannot cast from VUndef to Handle (VHandle)
markstos_ Oh. That's not what I get on feather...
Let's see which one is the problem. 12:54
?eval sub foo (*%args) { warn %args.perl; } foo( a => 'b' );
evalbot_12761 Error: Cannot cast from VUndef to Handle (VHandle)
markstos_ ?eval sub foo (*%args) { warn %args.perl; } foo( 'a' => 'b' );
evalbot_12761 Error: Cannot cast from VUndef to Handle (VHandle)
markstos_ Both! That seems perhaps /more/ broken. 12:55
Passing arbitrary name/value pairs to a subroutine has proven more difficult than I imagined!
agentzh ?eval sub foo (*%a) { warn %a.perl } foo(:a<b>) 12:57
markstos_ So how /does/ one pass arbitrary name/value pairs to a subroutine in Perl6?
evalbot_12761 Error: Cannot cast from VUndef to Handle (VHandle)
markstos_ Let me try that on feather. 12:58
agentzh markstos_: it used to work. :/
markstos_ That works here! Let me check the pugs revision I'm using. 12:59
r12728
agentzh i've used slurpy hash args in pugs' Test.pm.
markstos_ So something broke recently, it seems
agentzh and all the tests in t/02-test-pm/5-todo.t passed at that time. 13:00
not sure about the status right now.
audreyt and gaal are currently working on this part, say captures and signatures. 13:01
markstos_ backs up working pugs on feather for fear of impeding breakage.
agentzh so it may be temporarily broken. :)
markstos_ Where is the evalbot actually running pugs from ? 13:02
Juerd sub foo (Pair *@pairs) { ... }
agentzh ~audreyt/pugs
Juerd When I call foo with a list of pairs, do they need to be in double parens?
Or is there another way to break named argument parsing? 13:03
foo <== foo => 'bar', perhaps?
markstos_ That doesn't seem right. That's where /I/ was just testing from, and a different revision and result were reported. 13:04
On feather /usr/bin/pugs is a symlink to ~audreyt/pugs/pugs
Anyway, the :a<b> syntax is what I needed. You made my tests pass, agentzh!

marksto1 It'd be nice of S09 provided a reference to what PDL means in this context. I suspect it's different than the "Perl Data Language", located at pdl.perl.org/ 19:44

Juerd TimToady: You too, please 19:51
gaal Juerd: ask people to ack it if you want to be sure they'd seen it... 19:52
Juerd gaal: I can tell just by looking at directories.
gaal: Either:
* The message has been forwarded. I assume people check their normal email regularly. 19:53
* The message has been read, it is either deleted or in ~/Maildir/cur
* The message has not yet been read, it is in ~/Maildir/new
gaal asking for active ACK raises the likelyhood of action. :) 19:55
also, that way you don't have to worry they missed it (filtering, oversight) even though it was forwarded 19:56

markstos_ Should this be a syntax error instead? 21:21
?eval warn @.perl
evalbot_12765 Error: Cannot cast into Hash: VRef <Sub:0x896318c> 21:22
Juerd Not a syntax error. Rather, that it can't call .perl on the current invocant for there is none.
markstos_ Ah. Does that mean that .method is the same as self.method ? 21:23
Juerd No, .method is the same as $_.method
But $.method is the same as self.method
As is @.method, but then with array semantics
markstos_ Ok. I see the consistency there.
b_jonas "$.method"? seriously? 21:24
markstos_ is testing it now. 21:25
It doesn't work yet. 21:26
?eval class Foo { method a { $.b } method b { say "worked!" } } my $a = Foo.new; $a.a;
evalbot_12765 \undef
markstos_ If you change "$.b" to self.b, it works.
b_jonas or just to ".b" I guess 21:27
markstos_ ?eval class Foo { method a { .b } method b { say "worked!" } } my $a = Foo.new; $a.a;
evalbot_12765 OUTPUT[worked! ] Bool::True
Juerd b_jonas: Yes, seriously. $.method, @.method, and %.method will call self.method.
markstos_ So, $_ is set to the invocant there ? I guess so.
Juerd Which is very useful, given that "has $.foo;", "has @.foo;", and "has %.foo;" create an accessor method called "foo" 21:28
markstos_ Juerd, but it doesn't work now if it's true, as my example showed. self.b.
s/self.b//
Juerd Then you can access it via $.foo, @.foo, and %.foo respectively. Useful, isn't it?
markstos_: I speak about Perl 6, not Pugs.
markstos_ You mean, the spec, not the implementation. 21:29
Juerd Pugs lags behind the specs, naturally :)
markstos_ Sure.
dinner guests. &
Juerd Though this has been specced for quite a while
Pugs development has been about internal changes the past time
b_jonas what? so $.foo means both a scalar instance variable and a method call of self? 21:33
b_jonas looks up in S12 21:34
I don't understand. Does this mean that when you declare a public attribute to a class with 'has $.foo;' then a public accessor method of name foo is also created? 21:37
Juerd b_jonas: No, only a method call. 21:38
b_jonas: With "has", it is special syntax.
b_jonas: Yes.
b_jonas ah, I see
"Public attributes have a secondary sigil of "dot", indicating the automatic generation of an accessor method of the same name. "
I should read before I ask 21:39
Juerd And if you don't use the dot, the method is not created, and you have a normal variable, only instance-specific.
Also known as "private"
b_jonas I think I'll like this syntax 21:41
It's perl6ish.
