p6eval rakudo 4abd89: ( no output )
masak what are the rules with the above, overriding a method with another whose return type isn't the same or narrower? 05:11
is there a construct similar to this which restricts that kind of overriding? 05:12
05:14 frioux|home left
pugs_svn r26120 | masak++ | [u4x/TODO] diffy iffy fiddly 05:21
Tene_ looks like 'returns' types aren't enforced in rakudo ATM. 05:23
05:24 justatheory left
masak right. 05:24
specifically, it's still allowed to fall out of a sub or method with any old value. 05:25

 05:30
masak Tene: we talked about eval-in-current-scope once, a possible solution for a better Rakudo REPL. 05:32
Tene I remember that. 05:33
masak Tene: I've had a different idea since then, which might be worth considering.
Tene oh?
masak something like eval-in-the-following-scope.
it might be a bit more general, and useful for other things.
Tene Yeah, that's pretty much what I was going to do.
masak :)
I'm not sure how to say "the current scope" in Perl 6. 05:34
maybe &?ROUTINE or something similar.
05:34 Doubi left
masak but the point is that it's probably better to have a dedicated scope for the REPL evaluations. 05:34
but you already seem to have realized that. :) 05:35
...in which case I'm simply glad to have realized it too.

masak learning Esperanto ruined my French, sad to say. 06:27

masak I could probably pick it up again, with some work.

eiro moritz_, damned ... i have hard time to configure my client via IRC ... everything is set to utf-8 :(
moritz_, noticed :) 06:30
moritz_ eiro: I know that, it took me quite some time to get a decent setup working
eiro masak, i prefer to learn dead langages as latin or ancient greek vs esperanto: it helps to lean other langages 06:31
moritz_ terminal at home, then the local on the remote host, then screen, then irssi... very annoying
masak eiro: was the hosting-a-vim-user an example of extreme hospitability? would it be more generous to be hosting Emacs users, or less? :P
eiro (ok: it will be useless for swedish :) )
masak eiro: I've learnt a bit of Latin too.
eiro: no, not really useless.
the Vikings conquered England a while ago. that left some linguistic marks.
eiro masak, swedish is not a latin language ? indo-eurepean one, perhaps ? 06:32
masak eiro: correct.
but so are most languages around here.
eiro ok
so ... i'll earn my salary now :) 06:33

eiro wow ... i have pbs with very classical one 06:48
so don't be rude again with me :)
masak rude? us? :)
eiro masak, no: i replied to sitaram
masak I see. 06:49
sitaram he meant me -- sorry wasn't intended to be rude; a play on "latin". That's why I added the Wikipedia link
eiro sitaram, thanks for the link: i'll give it to my wife
sitaram apologies
eiro sitaram, it was juste a joke
sitaram ;)
sitaram wipes brow!
masak I'm glad we got that cleared up. 06:50
eiro in france, when we don't understand a word or a sentence, we roll our eyes on the guy and tell him to not be rude
(just popular joke ... i imagine that every nation have some)
pmichaud rolls his eyes. Another 7.
masak sitaram: I've now backlogged your joke. it was OK, I guess. :P I wonder what the Pig Latin equivalent to Greek would be? 06:51
sitaram aah -- we have something similar in India too, sometimes. We say "why are you swearing at me" or eqvt...
moritz_ sitaram: a -> Ī±, b -> Ī² ...
erm, I meant masak
masak moritz_: it's all Greek to me.

eiro TimToady, in fact my wife surnamed me 'eromai' ( 'i ask to myself' or 'i ironically ask' ) 07:23
it became ero ... which has no sense 07:24
rgs heauton eromoumenos ?
eiro i added the i ... now it mean: to say
rgs, i don't understood :-) (i actually don't speak greek: my wife does) and i begun to learn latin 07:26
rgs I don't guarantee this is good greek
that would be "the one who makes himself loquacious" 07:27
mberends would that be 'grok greek' here ? 07:28
eiro heauton : 'self'
that's the only part i read :)
masak all those /path/to/my/rakudo metasyntactic paths meant to be replaced -- I think we should standardize on /some/weird/place/rakudo. it stands out a bit more. 07:29
moritz_ search for define:loquacious with google and see how different the explanations are
chatty: full of trivial conversation; "kept from her housework by gabby neighbors"
Fluency (also called volubility and loquaciousness) is the property of a person or of a system that delivers information quickly and with expertise.
those don't sound equivalent, to me :-)
rgs we're in a semantic field where IRC nicknames can be easily chosen 07:31
eiro :-) 07:33
it's just the way my wife call me :-)

moritz_ wonders if 24.reverse should pick the List.reverse or the Str.reverse 07:54
masak moritz_: it's a scalar. it should pick the Str.reverse, IMO. 07:55
moritz_ maybe Str.reverse should be named Str.mirror
masak :)
seems a bit arbritary. might as well have been List.mirror and Str.reverse, no?
moritz_ not quite 07:56
for composed characters a "mirror" describes more accurately what happens to the string

masak ;)
mberends create a stub, and let the community fill in the details 12:00
masak mberends: well, that's one way to do it. in that case, we'd want it on a wiki. 12:01
but I'm thinking maybe we can get away with Less Work.
for example, proto can download all Perl 6 projects nowadays.
./proto install all
mberends the little eeePC will groan under that one 12:02
masak :)
pmichaud good morning #perl6 12:03
masak use with caution. 's all.

so it'd be conceivable to create a module that used proto to dump all the projects in one directory, and then performed a series of automated tests on them.

have fun ;-)

pmichaud jnthn: both Tene++ and I had some difficulty grabbing annotations out of exceptions
jnthn moritz_: Yes, I have 22 out of 29 of them passing now. But I broke a couple of others along the way... :-(
masak LylePerl: excellent.
LylePerl masak: That would make sense
jnthn pmichaud: Odd. Did you look at the annotations tests for examples? 12:11
pmichaud after your class... any clues you can provide would be helpful :-)
jnthn Sure.
pmichaud yes, did look at the tests
LylePerl Looks like I'll have to learn parrot :)
jnthn pmichaud: OK.
pmichaud I'll put together a patch with what I had thus far
masak LylePerl: me too. :)
jnthn pmichaud: More failing Parrot tests that pinpoint the issue could also be nice, if you can reduce it to that.
pmichaud: But don't worry if not. 12:12
Anyway, idem studovat. :-)
masak LylePerl: but the principle is the same as for any software bug: remove as many parts as you can to pinpoint the error.
mberends masak: Good Practices: same idea. in doing Pod Parser v2, I'm trying to learn from previous mistakes. more tests, more correct structure up front. Possibly your Test::ix as well.

in the bin/ dir of Druid.
LylePerl masak: That's difficult with the simple hello world script 12:15
masak LylePerl: why? 12:16
12:16 Tene left
LylePerl masak: because it's as bare bones as it can be 12:16

masak LylePerl: is it in Perl 6?
LylePerl masak: yes 12:17
masak LylePerl: in that case, the level below would be PIR.
LylePerl masak: I see :/
masak if you can produce the error in pure PIR, the Parrot people will be able to help you better.
LylePerl sounds like a plan
thanks for your help
masak LylePerl: Rakudo can output to PIR instead of running a script, if you ask it to.

OH!!
lift is an epicly confusing name for it
We should rename that op. :-)
Anyway, what it does is a find_lex starting in the *outer* scope.
pmichaud ...but what does it do, exactly, that is different from find_lex ?
jnthn Not the current one.
pmichaud ah. 14:21
jnthn It's for lexical multis to find their outer multi.
pmichaud do we need an op for that? Seems like it could be done with getinterp
in fact, we already have a sub for that.
jnthn Yes, but it was an easy op to write and lexical multis are kinda common. ;-) 14:22
So I sorta didn't want it to have much overhead.
phone
ah, phone fail 14:23
pmichaud in general I think we need better lexical ops.
14:26 minazo joined
jnthn Quite possibly. 14:27
Remember that imports are lexical by default.
pmichaud I never forget that.
it scares me :-)
jnthn It isn't completely unrelated that I started working on lexical multis shortly after I did the first package-based cut of importing. ;-) 14:28
But we really need to solve the class hides lexicals issue before we switch over to importing to the lexpad. 14:29

TimToady: if you commit, I'll do so too ;-)
TimToady I already committed 17:07
17:07 M_o_C joined
moritz_ ah 17:07
TimToady see above
moritz_ right
TimToady I shoulda said [t/*] or some such
moritz_ running the tests now
PerlJam does split also default to '' (as join)? 17:14
pmichaud flips for flip.
TimToady split doesn't default to anything
PerlJam $str.split.join eq $str # would be nice I think 17:15
diakopter moritz_: the irclogs links to S32 don't work.. sorry I don't have any suggestions to fix it. :)
TimToady it'll be bad enough that people expect split(' ') to work like p5 17:16
if they write .split they'll expect the same thing half the time
PerlJam that's probably true. I know I use @foo = split; all the time in perl5 17:18
it's only a small mental jump to expect @foo.split to do the same
er, @foo = $str.split 17:19
PerlJam can't type *or* think
pmichaud what is U+9FA6 ?!?
(yes, I know it's a unicode codepoint. What unicode codepoint is it supposed to be?) 17:20
moritz_ diakopter: I know, and I'll fix it as soon as we have HTML rendered S32 links
dalek kudo: 582e78c | (Moritz Lenz)++ | src/builtins/any-list.pir:
.join now defaults to empty separator
 17:21
TimToady pm it appears to be 1 off the end of the CJK region 17:23
17:23 araujo joined
TimToady so not a real character 17:23
pmichaud in looking at unicode.org/cldr/utility/list-unico...Letter%3A] 17:24
which (I think) displays all of the codepoints with the Lo property
it shows 17:25
U+4E00 ( äø€ ) CJK UNIFIED IDEOGRAPH-4E00
ā€¦{20930}ā€¦U+9FC3 ( éæƒ ) CJK UNIFIED IDEOGRAPH-9FC3
TimToady maybe they added some more that I don't know about
pmichaud which (I think) means that 9fa6 has the Lo property
Matt-W infix:<xx> isn't supposed to modify its left-hand argument is it?
PerlJam pmichaud: unicode.org/cldr/utility/character.jsp?a=9FA6 17:26
jnthn Matt-W: Don't believe so.
pmichaud PerlJam: yes, I'm also presuming from that page that U+9FA6 should be a valid Letter.
TimToady added in 4.1, it appears
17:26 ejs joined
Matt-W jnthn: didn't think so 17:26
pmichaud infix:<XX> itself doesn't modify its left-hand argument, but it also doesn't clone it. 17:27
lucs pmichaud: According to my copy of the Unicode Standard, version 2, U+9FA6 to U+9FFF are an unassigned block at the end of the CJK Unified Ideographs.
TimToady 4.1 17:30
so your version is about 2.1 versions out of date :)
lucs Right :)
pmichaud so, any suggestions for modifying the spectest?
should I pick 9fff ? 17:31
jnthn moritz_: I gotta run do a bunch of deployment stuff for a client now, but latest commits get most of the S09 arrays.t passing.
TimToady I don't know which spectest you're referring to
pmichaud oh, sorry 17:32
t/spec/S05-mass/properties.t
jnthn moritz_: 22 out of 29 it seems. Feel free to fudge and add to spectest.data.
pmichaud jnthn++ # more passing spectests
jnthn moritz_: Or I'll do it in a couple of hours when I get this other work done.
moritz_ jnthn: sure, will do
17:32 dalek left
jnthn Also, I wrote overlong commit messages and killed dalek. Again! 17:32
pmichaud or I could pick u+9fc4, which is one off the end of the (5.1) cjk region

TimToady any particular value seems fragile without versioning 17:33
pmichaud jnthn: did you bump build/PARROT_REVISION ?
jnthn pmichaud: I did.
moritz_ pmichaud: I have no particular opionion on that one, do as you wish
pmichaud jnthn++
jnthn pmichaud: But since the commit message that said so didn't appear here, thought I'd mention it. 17:34
pmichaud jnthn: got it.
well, if any value is fragile, I think I'll go with 9fc4 for now, and put a note in the file 17:35
moritz_ at least it appeared on #parrot 17:36
17:36 ejs left
PerlJam how do I "make spectest" but not the whole thing? 17:38
pmichaud how do you mean "not the whole thing"?
moritz_ PerlJam: make t/spec/path/to/file.t 17:39
PerlJam I just want to run the spectests in one dir
pmichaud if you want to do a subset of tests, create t/localtest.data and then make that
for one dir, make t/spec/dir/*.t
PerlJam thanks
moritz_ grep ^S06 t/spectest.data > t/localtest.data; make localtest

moritz_ I don't understand that 18:04
there are two split multis
pmichaud something isn't multi that should be
or
it's dispatching to the wrong multi
moritz_ if there's no PIR split leaking in I suspect the latter 18:05
both methods are multi
jnthn Are they defined on the same class?
moritz_ jnthn: yes
the sub form is not multi
(I'll fix that)
pmichaud oh, that's probably the problem.
or at least it might be a problem. 18:06
Parrot still has difficult keeping methods and subs distinct.
moritz_ but its delimiter has no type constraint (ie Any)
ok, let me try that
jnthn Also beware that if you call split(...) sub in a method and that class defines a method you'll end up calling the split method...
Which is probably a bug.
pmichaud (yes, that's the parrot bug I'm referring to) 18:07
jnthn ok
Matt-W if I declare a state variable inside a while block inside a sub, will it persist across sub calls or just loop repetitions? 18:09
jnthn across the sub calls unless the sub is cloned, I think 18:10

Matt-W thanks

moritz_ temp is NYI 18:21

TimToady I think maybe Hash.push should create sublists for dup keys
it means an anonymous attribute, which is pretty useless I expect 18:26
PerlJam I tend to want to outlaw useless constructs personally.
TimToady you could even initialize it "has $ = 42;"

moritz_ PerlJam: it shouldn't 18:30
PerlJam: because the spec tests are out of date
PerlJam moritz_: well, it passes after I modified them to use $str.flip where it currently uses $str.reverse :)
TimToady is there still a Str.reverse implemntation out there
moritz_ TimToady: out there yes - not in my local copy 18:31
but I suspect the test suite needs updates in several places
and reverse.t is *full* of str-vs-list distinguishing tests
PerlJam not in my copy :) 18:32

moritz_ if the current run is clean, I'll commit 18:41

LylePerl diakopter: setting up a handler mapping on IIS7. Still can't get rakudo to work on IIS though, I'm doing some more tests but I'm pretty sure it's a parrot issue

pmichaud jnthn: pong
cspencer is there a way that i can associate shift and shift_pmc?
pmichaud cspencer: we don't have a way to declare vtable methods yet.
(from Perl 6)
cspencer ah ok
literal diakopter: you can make one if you have vim
pmichaud in some sense you eventually won't have to .
because it'll be taken care of in Object or Any.
jnthn pmichaud: Are @foo[] and @foo[*] meant to be different?
diakopter I need html :)
literal diakopter: vim can do that 20:51
diakopter oh?
pmichaud jnthn: in general, I don't think they're different.
jnthn pmichaud: For the first, in method postcircumfix:<{ }> we're doing:
literal :TOhtml
jnthn .tailcall self.'list'()
However for @foo[*] we do
cspencer pmichaud: is the solution similar to defining the get_number method in Object.pir?
pmichaud cspencer: it might be -- I haven't tried it yet.
diakopter literal: thanks; nm; I remembered the script that does that here..
jnthn result = 'list'(self)
cspencer ok, i'll check it out and see what breaks :)
jnthn pmichaud: I wondered if it was an intentional difference or not. I don't need to change it really. It just got me curious. 20:52
masak @tell mberends oh, and for some Pod6 tests, November's Test::InputOutput might be more fitting. use.perl.org/~masak/journal/37976
lambdabot Consider it noted.
pmichaud jnthn: I can't remember why there would be any difference between them.
feel free to re-work it. But also note that our handling of * has to change also. 20:53
jnthn pmichaud: OK. Thing is I sort of suspect they could potentially end up giving different results.
Yeah, I'm not worry about that bit right now. :-)
pmichaud in general there is/can be a difference between .'list'() and 'list'(), yes. 20:54
TimToady yes, they're different 20:56
since [] is 0 dimensional, not 1 dimensional like [*]
so @foo[].WHAT is Array, while @foo[*].WHAT is List, I expect 20:57
moritz_ pmichaud: your recent commits to the test suite have many insertions but no deletions - is that intentional?
pmichaud that is likely to be the difference. Also, if you're looking at postcircumfix:{ } -- chances are that I just copied it from Positional without investigating it too thoroughly.
literal masak: heh, I would have just stuffed all those strings in an array of arrays and looped over it
masak literal: that's what it does.
pmichaud moritz_: I'm wanting to finish the refactor before I remove properties.t

masak IIRC, 'return ()' returns an empty list, aka Nil.
whereas 'return' returns undef. or something like that. 21:07
moritz_ I thought both return Nil, which is undef in scalar context, and the empty list in list context?
pmichaud note that return() is different from return ()
and "return;" is the same as "return();" 21:08
literal yeah
masak aye.
makes sense.
21:08 payload joined
moritz_ pmichaud: but is () an empty list? or is it a no-op? 21:08
pmichaud it's an empty list
literal so what does "return;" mean in list context, then?
pmichaud an empty list.
"return;" in scalar context gives an undef value. 21:09
literal ah, but "return ();" is Nil ?
pmichaud no.
[particle]- that tells me "return;" returns Nil
pmichaud "return;" gives back Nil. Nil is an empty list in list context, and undef in item context.
[particle]- return (); returns empty list, which in scalar context, is ?
literal so, there's no difference between "return;" and "return ();" in any context?
pmichaud an empty list in scalar context becomes a Capture 21:10
(with no positional values)
[particle]- there's the difference.

moritz_ somebody[tm] told me that () in Perl 6 only had grouping functions, and never construct lists
is that somebody wrong? 21:11
pmichaud () produces an empty list. Outside of that, it is used only for grouping.
masak moritz_: in this corner case, yes.
literal so what would "return Nil;" do?
masak literal: return Nil? :)
moritz_ literal: probably the same as 'return;' 21:12
literal ok

masak I've gotta blog about Test::Ix, before I forget how it works. some of that code scares me a little. 21:16
such as the code that finds a variable declaration in another file, and executes it.
or the code that figures out how many params a sub wants, and provides that number of params when calling it.
moritz_ .arity? 21:17
masak aye.
moritz_ seems pretty standard to me ;-)

pmichaud okay. allison and I were discussion our plans for YAPC::EU -- we may want to do a parrot meeting of some sort there.

jnthn OK. Is there not one at YAPC::NA (the VM workshop)?
pmichaud I think that's more aimed at people who are interested in working on Parrot. We were thinking of something like PDS -- i.e., planning for 2.0 23:56
jnthn Or more a smaller Parrot-Rakudo meeting?
Ah, OK.
pmichaud (well, it was more allison's idea than my own :-)
jnthn I had thought PDW would incorporate the planning for 2.0 too.
But makes sense to separate them.
And having it in Europe would be nice. :-)
pmichaud I'm just trying to solidify my travel plans, and try to see who can fund them :-) 23:57
jnthn I can easily tack on extra day(s) for a PDS anyway.
pmichaud anyway, good to know you're likely for YAPC::EU.
jnthn :-)
Also at NPW I'd like to work out my next Hague Grant application, since typed arrays and hashes are coming together nicely now. 23:58
And they were pretty much the last thing I have left to do on the current one.
pmichaud yes, we should do that also.
jnthn I guess by then you'll have the roadmap updated too, which will be good input into that.
