PerlJam TimToady: this is what I expected but, then I also tended to expect { XXX; my XXX } in general to carp. Would it be safe to say that it only carps if XXX is a variable?
TimToady only functions may be post-declared 02:16
sorear it's kinda like ANSI C
when an undeclared function is seen, a declaration is automatically generated assuming that it has listop precedence
so in the common case, postdeclaring works 02:17
TimToady well, all C functions are global, to the first approximation, and the call syntax is relatively unambiguous
sorear Haskell allows postdeclaration of functions with /any/ precedence
which makes the parsing algorithm completely insane 02:18
TimToady probably forces multiple passes
diakopter murmurs about the insanity defense of accusations of insanity
PerlJam I understand it, but my brain isn't accepting it for some reason. I used to think that "my XXX" meant than XXX existed from that point forward to the end of the inner-most enclosing scope. Having functions not do that *and* be lexical is bothersome
s/than/that/ 02:19
sorear for a long time I thought it was undecidable, but eventually I came up with an EXPTIME algorithm which tentatively assigns each possible combination of precedences before trying to parse

viklund how much of the divergence is bacause of adjustments to how perl5 works and how much is divergence from discovering "best practices", would be interesting to know... 07:46
what is variable attribute representations? 07:47
moritz_ sorear: re named arguments with weird names: you can always do foo(|%h)
sorear: where %h can has arbitrary keys 07:48
moritz_ backlogs
Herve++ posted an interesting comment on my blog 07:55
he suggested to change the triangle form of reduce from [\+] to [@+]
with the rationale that @ indicates a list-ish return type 07:56
I wonder if we could even change to that @[+] to disambiguate infix operators starting with @
TimToady: what do you think about that? (when you backlog :-) 07:57
sorear viklund: in perl6, attributes are just variables. in Moose, attributes have a meta object with overridable accessor code 08:01
so you can have attributes that do fancy things when written to, etc
moritz_ you can have that too in Perl 6 08:02
sorear moritz_: You could hear that behind the noise of "OMGZ METAOPS ARE WRITE ONLY"?
viklund ahh, yes I knew that, just hadn't heard the phrase before...
moritz_ if you use a modified storage backend
viklund sorear: thx
moritz_ sorear: I try hard to focus on the constructive part of the critic
sorear I think the divergence is because the Moose cabal has given up on Perl 6 and decided to drop all connection with the Synopses
08:02 bbkr_ joined
sorear but then I'm just a cynic 08:02
moritz_ sorear: for sure the Moose folks chose whatever fits best for Perl 5 08:03
sorear moritz_: can you give me a short code sample for that? 08:04
moritz_ sorear: and introducing $!foo variables isn't easy in Perl 5 at all :-)
sorear: no
it would have to be some sort of object being passed as the REPR to YourClass.bless 08:05
which has FETCH and STORE methods
sorear $!foo is hard-wired to access the object representation
moritz_ that do the fancy stuff
yes, but the object representation isn't hard wired
sorear with pervasive accessors, you get an extra layer of indirection
which makes this absolutely trivial
has 'foo' => ( trigger => $SUB )
just sets an attribute on the attribute
which changes code generation 08:06
08:06 bbkr_ left
sorear I'm not following the Perl 6 idea of "our approach must be better because it uses $! variables" 08:06
moritz_ well, you can still use lvalue accessors if that's what you want
and don't use the $!foo variables at all 08:07
just like you can also use $self->{foo} in Moose, if you want (iirc)
08:08 snarkyboojum left
sorear how does an lvalue accessor do anything interesting? 08:09
the only way to make lvalues 'interesting' is to tie them
does perl 6 discard the taboo against ties?
moritz_ I'm not sure; it's something I forget everytime I read it up because nobody implements it yet
should be in S06 somewhere 08:10
sorear Why isn't it trivial?
moritz_ ask @Larry :-) 08:11
I have no idea
I can't remember how lvalue subroutines work in perl 5 either 08:12

that's duplicate semanteme
moritz_ there's no reason for the second @(...) at all 08:39
JimmyZ I mean @[] or [@] is duplicate semanteme ;)
just in my opinion 08:40
moritz_ and I disagree, becaue the @ is about the return value and [] is about the arguments
this is just like saying "I don't like our Num sub sqrt(Num $x) { ... } because Num appears twice" 08:41
but they serve different purposes
JimmyZ I don't think operaters need return type .
moritz_ well, I guess liking and disliking can't always be rationalized

pmurias: 04:40Z <diakopter> tell pmurias I can re-enable the trampoline when a possibly-recursive invocation is detected, but the addl cost will be another slot for the return value per callsite in each recursive frame.
[Sorry, some messages were elided and lost...]
pmurias why are messages elided? 09:23
jnthn sorear: I think it's maybe a grey area in the spec, though I'd like it to work.
sorear because phenny tried to paste the remainder to paste.lisp.org with an outdated captcha key
it should just be using App::Nopaste
jnthn: I don't like it all that much because if I misspell an event, nothing will warn me. 09:24
However, my options are rather limited by Rakudo's limited support for the MOP
I think for now I'll just give my methods names like _handler_FOO_uniquey() and rely on introspection for event dispatch 09:27

Su-Shee which means one can easily define whatover one wants to be a core module. :) 11:31

11:31 kst joined
masak well, it seems that that kind of 'core' will be up to distributions of Perl 6, not the spec. 11:34
Su-Shee masak: I like tiny cores. I like adding modules depending on the need. 11:36
and why not make a "security related math libs" distribution or a "gui-all-you-ever-need" distribution.. :)
moritz_ tiny core... then Perl 6 is not for you :-)
masak Su-Shee: me too. but I also know I draw the line somewhere.
Su-Shee I realized that already. ;) 11:37
masak Su-Shee: for example, impoting 'stdio' for IO in C feels silly.
Su-Shee masak: excellent example I would totally agree.
moritz_ anyway, I'd welcome some attempts to make DateTime, Date and various container types non-core, but still with a somewhat built-in feeling 11:38
Su-Shee moritz_: from a user's point of view I essentially don't want to "feel" the difference between "is core, is builtin, is cpan"
masak moritz_: not sure what you mean. what more would it take than putting `use DateTime;` at the top of the program? 11:40

moritz_ masak: integration with other modules or core things... 11:42
masak moritz_: it's the latter thing that concerns me.
moritz_ for example now that 'now' returns an Instant, I think time() could return a DateTime
(if we need time() at all)
masak seems that we can't have both 'time' as a builtin and DateTime as non-core. 11:43
moritz_ so... move DateTime and time() both out of core? 11:44
masak well, I'm still a bit doubtful. 11:46
wouldn't filetests need DateTime, for example?
those are definitely core.
moritz_ no, they need Instant only
masak ok.
moritz_ maybe I should compile a list of types that could be non-core 11:47
masak I'd like for DateTime to end up as 'almost core', i.e. something that most distributions will want to pull in.
moritz_ aye
masak things like timezones and localizations may well be CPAN-style modules.
i.e. not necessarily 'almost core'. 11:48

moritz_ while I was writing my reply, I realized that proto and cpan differ quite significantly 12:53
cpan is push-style: each version is uploaded to pause.cpan.org
while our current approach is pull-style: the meta data is kept central, but the source code isn't kept in one place 12:54
masak *nod*
moritz_ not sure which approach is preferable in the long run
masak proto was never meant to be like CPAN. it was created to solve a piece of immediate pain.
moritz_ I know, you keep repeating that :-)
pmurias keeping the source code in one place seems very sensible
masak moritz_: I keep repeating it because I'm constantly surprised about the new things that proto starts to mean to people. :) 12:55

colomon I dunno. 13:22
13:22 meppl joined
colomon here's the deal. 13:24
moritz_++ pointed out that arithmetic was still using .Num instead of .Numeric internally.
as a result of thinking about that a bit, I started adding tests like "1" + 3i to complex.t 13:25
in theory, the way they should work properly now is: 13:26
"1" + 3i dispatches to infix:<+>(Any, Any)
moritz_ rakudo: say '1' + 3i
p6eval rakudo e16cf4: OUTPUT«1 + 3i␤»
colomon that calls +"1" + +3i
moritz_: that works now because there is an infix:<+>(Any, Complex) 13:27
I'm trying to get rid of that.
and (concluding) +"1" + +3i dispatches to infix:<+>(Real, Complex)
moritz_ but prefix:<+> should already call .Numeric, no? 13:28
colomon moritz_: yes, it does. but the existing versions of infix:<+>(Any, Any) calls .Num on each argument instead. 13:29
moritz_ ok
so that needs fixing too
colomon the change to use +$a + +$b is only local to my system at the moment.
thing is, that works great
afk for sec

moritz_ and that's for '1' ** 3i, or what? 13:36

isBEKaml hi #perl6! 16:17
masak hi isBEKaml! 16:18
isBEKaml I feel like looking at a module today... what's already in? :)
masak isBEKaml: you mean writing one? 16:19
sorear try src/core/*.pm
isBEKaml masak: no, reading one! ;)
masak oh! well, what sorear said.
isBEKaml: I can recommend Druid, too. it's a documented, OO board game in Perl 6. github.com/masak/druid 16:20
sorear src/core/*.pm isn't exactly modules, but it's the largest body of reusable Perl 6 code we have
masak sorear: largest? on what do you base that?
the spectest suite is pretty large.
November and GGE are large projects.
[particle]1 STD.pm is pretty large 16:21
...and that's just one module...
diakopter _reusable_, sorear said
masak STD.pm might be the largest reusable piece of Perl 6 right now.
sorear masak: A weighted function of size and reusability
isBEKaml YOU_ARE_HERE.pm; a single line module, yay! :D
sorear STD.pm is huge but it's only good for one thing
diakopter agrees
masak hm. I need to think about the difference there. 16:22
STD.pm5 isn't reusable because it's only good for one thing?
[particle]1 where on earth are the p6 acme modules??!?!!!?
masak even though that one thing is parsing Perl 6?
sorear masak: it is reusable. just, less so than stuff like Hash.pm
jnthn isBEKaml: That's just there to make people think, "wtf?" ;-)
colomon pir folk: any way to do the equivalent of .?call in pir? 16:23
jnthn Ew!
Yes
But I'll have to look it up
colomon maybe there's a better way?
sorear colomon: src/glue/dispatch.pir
jnthn See src/glue/dispatch.pir for the thingy to call.
sorear !dispatch_.?
jnthn It's got .* in its name.
oh, .?
16:24 ash_ joined
jnthn What sorear++ said. 16:24
sorear .? actually does two things
colomon I've patched assign_metaop to take the value of the op called with no parameters.
sorear it guards against the method not existing
and it guards against MMD failing
isBEKaml jnthn: :). Anyway, I was thinking of PIR code generated when building Rakudo after checking out Parrot... Was that all auto generated?
sorear if you only want to do one of these things, you can get away with less code
isBEKaml jnthn: I tried reading them, looked close to heavy metal bytecode..
colomon which works great unless there is no version that takes no parameters.
sorear isBEKaml: Everything in src/gen is autogenerated compiler output. 16:25
jnthn Yup
diakopter \_o_/
sorear There's a fair amount of handwritten (i.e. commented and with sane register names) pir, in src/builtins, src/cheats, and src/glue
jnthn Pretty much the only hand-written PIR lives in src/builtins/ and src/glue/ iirc.
sorear oh and src/metamodel
isBEKaml eww, does anybody ever handcode PIRs? 16:26
sorear Yes
Look inside your libc sometime, you'll see plenty of assembly there too
same reason, really
implementing the entire Perl 6 standard library in Perl 6 has bootstrap issues 16:27
colomon errr, ick. actually I need the sub equivalent of that, if there is such a thing, now that I think about it.
sorear $P0 = get_hll_global "&my_sub"
isBEKaml I thought handcoding assembly was so long ago, unless you really need to get close to hardware.. That isn't the case with perl6, right?
sorear if null $P0 goto not_found
$P0()
colomon sorear: in this case &my_sub should exist, just with a different signature than I need to use. 16:28
sorear isBEKaml: Libraries can't just float in mid-air, they need to be anchored to the bare metal *somewhere*
ash_ isBEKaml: anytime you port say the GCC to new hardware there will always be handcoded assembly, in embedded systems its happens all the time
masak swimming &
16:28 masak left
jnthn isBEKaml: Calling it assembly and thinking the same was as hardware-level assembly is making it out a bit worse than it is though. 16:29
isBEKaml ash_: I can understand embedded systems, yes...
jnthn isBEKaml: All your objects are garbage collected, don't need to manage calling conventions by hand, etc.
ash_ pir has a lot of nice things, its a bit above assembly
isBEKaml jnthn: I didn't mean that way.. I didn't even call them assembly, I said they looked like auto generated bytecode, akin to java bytecodes.. 16:30
[particle]1 isBEKaml: how would you implement infix:<+> in pure perl 6?
isBEKaml jnthn: sorry if I came out wrong..
sorear isBEKaml: Yes, they're evil. We know. 16:31
Are you complaining?
There's no alternative.
ash_ [particle]1: I would use a NCI system to call libc to add them together, :P
isBEKaml sorear: No, not complaining. Just curious why people would still hand-code those bytecodes... 16:32
sorear ash_: How would you implement the NCI in perl 6?
[particle]1 my platform doesn't have libc :P
sorear isBEKaml: see [particle]1's responce before last.
ash_ sorear: thats a different question all together
jnthn isBEKaml: The hand-written stuff looks rather nicer than the generated stuff. :-) 16:33
isBEKaml: The overall direction is to write *less* in PIR rather than more, though, that's for sure.
[particle]1 the generator isn't as smart as the humans yet
isBEKaml sorear: I'd have thought C, but not assembly.. :)
16:33 [particle]1 is now known as [particle]
colomon isBEKaml: which is why I flounder when I have to break down and write PIR. 16:33
sahadev rt.perl.org/rt3/Public/Bug/Display.html?id=60672 says: "According to S29, there should be an sprintf directive %C, ...". I looked at S29 (perlcabal.org/syn/S29.html), which points to S32-setting-library/IO.pod for printf. But the latter (svn.pugscode.org/pugs/docs/Perl6/Sp...ry/IO.pod) also doesn't contain any reference to sprintf. 16:34
what exactly does %C directive do?
ash_ i'd probably bootstrap a subset of perl6 that can self compile, a subset that can be directly translated to native code, then go on from there
TimToady sahadev: beats me..complex?
moritz_ sahadev: it's actually in S32-setting-library/Str.pod
sorear isBEKaml: Well... we do that. Everything in src/Perl6/ is written in our "C" 16:35
moritz_ The special format directive, C<%C> invokes the target argument as
code, passing it the result string that has been generated thus
far and the argument array.
sorear As well as the .pm modules in builtins/ and cheats/
sahadev moritz_: thanks. found it.
TimToady moritz_: I don't like @[] because I don't like noun markers attaching themselves to verbs.
isBEKaml colomon: gee, looks like I'll be learning the way around things here too... :D
TimToady how *do* we format a complex?
colomon rakudo: say -1 + 3i 16:36
p6eval rakudo fe59fa: OUTPUT«-1 + 3i␤»
moritz_ is there any free format string? :-)
TimToady rakudo: say -1+3i
p6eval rakudo fe59fa: OUTPUT«-1 + 3i␤»
TimToady what if I don't want to output the spaces? 16:37
colomon rakudo: my $a = -1 + 3i; $a.comb(/\S+/).join.say
p6eval rakudo fe59fa: OUTPUT«-1+3i␤»
colomon ;)
moritz_ colomon++ :-)
TimToady rakudo: my $a = -1 + 3i; $a.words.join.say
p6eval rakudo fe59fa: OUTPUT«-1+3i␤» 16:38
moritz_ or you sprintf $c.re and $c.im
TimToady :P
sorear What's the canonical Perl6 way to lift a smartmatcher?
jnthn rakudo: my $a = -1 + 3i; say "$a.re()+$a.im()i"; 16:39
p6eval rakudo fe59fa: OUTPUT«-1+3i␤»
sorear I want to find everything for which { $^a.Str ~~ m/.../ }
isBEKaml What's a GatherIterator() ?
ash_ rakudo: my $a = -1 + 3i; say $a.perl;
p6eval rakudo fe59fa: OUTPUT«Complex.new(-1, 3)␤»
sorear Rakudoese for a lazy list ATM
(subject to change)
isBEKaml rakudo: my $str="helpoworld".split(/o/,:all); say $str; say $str.WHAT;
p6eval rakudo fe59fa: OUTPUT«help o w o rld␤GatherIterator()␤»
sorear a GatherIterator looks kinda like an array but can be infinite and is not calculated all at once 16:40
moritz_ and should be called List or Seq or Array or so
TimToady "everything" seems underspecified
sorear tokens are only split from that string when you need them
TimToady: everything is a list of methods.
currently .grep({ $^a.Str ~~ m/.../ }) but that feels wrong 16:41
isBEKaml sorear: iterator, hmmm... why can I just display it in one fell swoop then?
TimToady why does it feel wrong?
moritz_ isBEKaml: because the consumer (here say) iterates it
sorear TimToady: the point, mostly 16:42
isBEKaml sorear: if that's an iterator, I should only be able to do something like next() until it exhausts itself, right?
moritz_ sorear: .grep(/.../)
sorear: it will stringify internally anyway
sorear: and .grep does a smart match against its argument anyway
16:42 molaf joined
isBEKaml moritz_: I don't understand the behaviour of "say", maybe I should go look at it again... You're saying it just doesn't do printing stuff, but more than that, like eat a _potentially_ infinite array/seq... :| 16:43
moritz_ isBEKaml: well, how else would it print their contents? 16:44
isBEKaml: actually it just calls .Str on its argument
TimToady each argument, surely 16:45
moritz_ isBEKaml: the the iterator consumes itself to generate the string representation of its argument
isBEKaml moritz_: so it stringifies whatever is passed to it?

TimToady well, maybe Num is different from Str that way
sorear it seems that smartmatching against rx// is doing something extremely wrong 16:52
TimToady but perhaps .Num ought to blow up on a Junction, so we can make sure + is calling Numeric
jnthn Auto-threading methods on junctions plays interestingly with coercions. :-) 16:54
SomeType(1|2) => Junction of SomeType instances, not SomeType
16:55 riffraff left
jnthn Thankfully though not a problem for 16:56
sub foo($x as SomeType) { ... } 16:57
Which will still auto-thread just fine.
(Because a junction is not Any)
TimToady well, maybe Str is just special in having a multi that takes Junction 16:58
16:58 spinclad joined
TimToady we have to give the low level stringifier used by say and print a name of some sort 16:58
and .Str doesn't seem so bad as long as .Stringy provides ~ semantics, which do autothread
jnthn *nod* 16:59
I'm not complaining as such, just pointing out the various interesting semantics. :-)
lisppaste3 sorear pasted "Insane bug w/ rx and for?" at paste.lisp.org/display/98544

I think it defaults to undef if there isn't one though
jnthn didn't check the patch yet
BTW, spectests actually aren't horrifyingly slower, it seems.

[Coke] jnthn: weren't we hoping for 10% faster?
moritz_ [Coke]: that's kinda defied by code generation using many, many concatenations, no?

[Coke] ah, yes. I am reminded to dig into CodeString to see if there was an easy fix there. 19:46

diakopter that one needz an empty string 19:47
[Coke] moritz_: looks like it would be pretty easy to convert CodeString to do it the fast way internally.
moritz_ diakopter: works here, with newest rakudo
[Coke]: then go for it :-)
diakopter ? p6eval should be newest
[Coke] If someone volunteers to benchmark it, I can craft a patch for that this $evening.
diakopter unless that was committed in the last hour 19:48
moritz_ diakopter: it was 19:49
diakopter oh :)

[Coke] moritz_: absolutely. I guess I can do that myself, huh? =-)
ash_ it does $!a, and $a okay, but $.a gives me a parse error
jnthn ash_: NQP doesn't implement that. 19:57
moritz_ ash_: ah, then use $!a
ash_ oh, okay
jnthn (Intentionally.)
moritz_ and write an accessor if you want one
ash_ so in nqp is "has $a" a mistake?
moritz_ std: has $a 19:58

moritz_ ash_: I'm not sure what it is meant to mean... a class attribute maybe? 19:58
19:59 goksie left
ash_ in perl6 the spec says class Foo { has $a } is the same as class Foo { has $.a } (i believe) 19:59
i was just wondering what it meant in nqp terms
19:59 jaldhar left
moritz_ maybe look at the PIR that nqp generates for it 20:00
[Coke] moritz_: oooh. there's a lot of concat going on in CodeString. *glee*

moritz_ [Coke]: is .'emit' a method in CodeString? 20:05
20:05 kensanata joined
moritz_ seems like, yes 20:05
and that method looks like a hot path to me 20:06
ash_ interesting 20:07
$a and $!b both act the same, as private variables
in nqp 20:08
[Coke] moritz_: yup. I can definitely clean tht up.
20:08 pyrimidine joined
ash_ since they are attributes, they both end up calling " getattribute $P34, self, "$a" " or getattribute $P34, self, "$!b" 20:09
so functionally, they are equivalent
colomon actually, op= defaults to failing at the moment if there isn't a 0-arg form of the operator defined. 20:10
patches welcome. ;)
ash_ hmm, thats odd, one minor difference between the two, one made a find_lex lookup for "self" the other just used self 20:11

what cs course
pmurias somebody in your uni suggested implementing stuff that way?!

diakopter hasn't taken a cs course
