Make ICU a hard requirement for parrot

Perl 6 is inherently a Unicode-aware language, and parrot without ICU is not. We seem to have trouble maintaining tests that do not depend on Unicode features, which tells us that not having Unicode is not acceptable.		 07:31
FROGGS nice :o) 07:32
moritz note that this is in a branch, to be merged after this months release
FROGGS moritz: now I wonder how that will work out on windows...

FROGGS yes, I think it is possible to have ICU on windows, but it was hard to set up IIRC

Tekk_ really stupid question since this is my first module. What would be an appropriate name for a module which is specifically pure perl? Relative to one that just binds up to a C library 13:34
PerlJam Tekk_: why should the implementation details affect the name? 13:35
BinGOs ::ButPurePerl ?
Tekk_ PerlJam: because the one that wraps the C library already has the nice name :P 13:36
tadzik Tekk_: what module is that?
PerlJam Tekk_: So?
Tekk_ I wasn't sure if there was some convention for that
tadzik: MPD
moritz Tekk_: in the perl 5 community, they often append ::PP
tadzik Tekk_: feel free to just hijack the name MPD
Tekk_ moritz: thanks
moritz JSON::PP, Text::CSV::PP etc.
tadzik Tekk_: I think that module is mine :P
Tekk_: I can rename mine to MPD::libmpd
moritz yes, tadzik is right. 13:37
Tekk_ tadzik: oh, it is :)
moritz and the current MPD isn't terribly active
(last patch: 2012)
tadzik to put it mildly :)
moritz April 2012, to be more precise
Tekk_ yeah, that's why I was working on mine. I figure it's a decent next step after playing around yesterday
PerlJam Tekk_++
Tekk_ MPD::PP works
moritz Tekk_: go with MPD. For sombody who doesn't know what that is, that's already obscure enough 13:40
PerlJam Tekk_: or you could spell out the name (and keep an MPD alias for the lazy) 13:41
tadzik Tekk_: I'll rename mine to MPD::libmpd, consider MPD namespace yours :)
Tekk_ tadzik: sure
PerlJam: I'm not sure about that. If you're writing an mpd client you probably already know what mpd is, given that it's the binary name :)
13:43 anaeem1 left, anaeem1_ joined
PerlJam maybe. Or maybe I don't know what it is but I want to write a Perl program that acts as a music player daemon ... but wait, maybe there's already one out there. 13:43
Would I search for MPD or something else? :) 13:44
Tekk_ PerlJam: it's not for acting as a music player daemon, it's for interfacing with the existing one. I do kinda see your point though
does anyone have a link to socket documentation? I can never find anything on docs.perl6.org 13:45
PerlJam suddeenly wonders if the META.json spec includes keywords.
moritz Tekk_: there is none yet :(
Tekk_ moritz: that would be why I have such a hard time finding it then :)
documentation as a whole seems pretty lacking, unfortunately 13:46
moritz Tekk_: perlcabal.org/syn/S32/IO.html
the specific is your best bet, at the moment
unless you want to read the source code 13:47
Tekk_ I was trying to look in the http client lib but couldn't find it. the spec should help at least
PerlJam notes that IO::Socket is in the "Here Be Dragons" section :)
Tekk_ but apparently now I need to go get a chair massage, so I'll bbl

13:53 anaeem1 joined
Tekk_ hmm...rakudo on moarvm doesn't seem to have io::socket for me.. 13:54
moritz Tekk_: you don't need to 'use' it 13:56
Tekk_: it's all built-in
Tekk_ oh 13:57
you can tell how much I've used perl 5 and 6 :P
moritz Tekk_: and you can tell you're not the first one to fall into that particular trap :-) 13:58
[Coke] Is anyone other than me using t/spec/test_summary ? 14:03
moritz [Coke]: iirc pmichaud++ used it 14:05
bartolin [Coke]: I am, but only for my clone of your perl6-roast-data.
moritz though it's been a while :-)
[Coke] ok. I am pondering 1) making it work with -j and 2) rewriting it in perl6. 14:06
bartolin for me, that's absolutely no problem 14:07
[Coke] the thought being that if someone needs to run it on their new implementation, they can use an installed rakudo-m or something.
moritz [Coke]: at that point you should consider doing it as a frontend for leont++'s TAP::Parser module
[Coke] moritz: excellent point.
TAP::Parser isn't in the ecosystem. 14:09
14:09 thou joined
leont It is, as TAP::Harness 14:09
moritz sorry, forgot the exact name, and guessed wrong 14:10
[Coke] we need a better ecosystem search! ;)
that could go in the meta info and be searchable.

[Coke] ^^ parrot is down to 3 failures. moar & moar-jit both exploded. 16:44
jvm at 12 failures.
colomon …. exploded with 100% passes? 16:46
and isn't moar jit by default now?
16:46 ajr_ left
[Coke] yes, I'm specifically testing it without because not everyone has jit. 16:47
colomon: not sure what you're looking at: that commit message says that rakudo.moar-jit failed 175 tests, and rakudo.moar failed 112.
lizmat the delete-adverb fail looks a lot like some of the core setting failures I get after some changes 16:48
[Coke] I could rename thm to -jit and -nojit if that would help.
lizmat of course, when run by itself, there is no issue?
[Coke] and also because, like today, they fail differently.
colomon [Coke]: looking at the percentage. So moar has more fails but also more passes than jvm? 16:49
lizmat [Coke]: fwiw, locally: All tests successful.
Files=931, Tests=34002, 171 wallclock secs ( 9.23 usr 3.17 sys + 1014.88 cusr 155.92 csys = 1183.20 CPU)
colomon percentage column, I mean
timotimo colomon: moar has more features enabled 16:50
[Coke] from the readme:
Note - the percentage column shows the percentage of the implementations against each other for that day's run - so the highest number of passes is always 100%, and the others are in relation to that number. So, 100% doesn't mean "passes every spectest".
timotimo we didn't port all of the async stuff to jvm yet and the jvm doesn't have our improved unicode database

is this really a bug?
I'd tend to say "no", but I'd like to hear other opinions too 17:36
vendethiel moritz: well, if I override our equivalent of toString, I certainly expect it to get called 17:37
PerlJam moritz: why do you think it's not a bug? 17:38
moritz PerlJam: because there's no spec, for one 17:40
PerlJam That is an *excellent* answer. :)
moritz I can see his point too 17:41
currently, the .gist fallback does some magic woodoo
it's not just the magic woodoo he expects
moritz tries a different magic gist, and re-spectests 17:42
but if it doesn't call .perl on its elements, it shouldn't look like .perl either 17:44

Tekk_ is there any particular reason that print will call .Str on a class but not say? 21:52
rather than just returning whatever the constructor was
timotimo yeah, say is for human-friendly (or rather: developer-friendly) output, while print is more "low level" 21:56
21:57 virtualsue left
Tekk_ timotimo: that's rather counterintuitive then in my mind 21:57
what method am I supposed to fill in to make say say the right thing?
my particular case was when I spent quite a while scratching my head over why say instance; wasn't returning the nice pretty printing that I put in Str :P 21:58
before trying print
timotimo say $foobar.Str
Tekk_ yeah
timotimo oh, you want say $foobar.perl in that case
Tekk_ o
no
not pretty printing the code, but showing what the data is in a nice way

lizmat decommute from NRPM&

Tekk_ okay, so Str is for print, perl is for Say 22:01

timotimo i mean: what classes are you trying it on 22:02
Tekk_ oh 22:03
my own
timotimo in that case, you won't have any sensible .Str implementation
there's .Str, which is the to-string-coercer 22:04
Tekk_ mhm
timotimo and .gist, to give a human-friendly output that may elide some stuff
Tekk_ I was just confused about what I should be filling in
timotimo and .perl, which is supposed to give something as close to eval-able as possible
Tekk_ ah
so why doesn't say use .gist rather than .perl?
timotimo the default .gist will just call .perl 22:05
so it probably *is* using .gist, but you didn't implement a .gist so it falls back to .perl instead
Tekk_ ah 22:06

frew How solid are the optional static type checking features? 23:16
frew has gradual typing lust
timotimo we're missing bits and pieces; what exactly are you interested in? 23:17
vendethiel has been posting some examples of "dependent type"-like things you can do with roles
frew mostly coderef arity checking
thats what I feel pain from the most 23:18
timotimo he's quite interested in strong type system stuff, so he's testing and fiddling with that aspect a lot
frew so foo takes a sub that takes 2 args and returns 1 scalar
ok
timotimo if you have a lexical sub or multi sub or a private method or multi method call, you'll get compile-time errors if you have the wrong arity or types
sadly, the server camelia runs on is busted somehow, when you try to evaluate code on the channel, you'll get "(timeout)" 99 times out of 100 23:19
frew is uh, my $f = sub (...) { ... } a lexical sub?
I installed rakudo from git already :)
timotimo "my" is lexically scoped, but you can re-assign $f later; you shouldn't get compile-time errors from that 23:20
m: sub takes_three($a, $b, $c) { }; takes_three(1, 2);

frew right..
but like
what if I want the re-assignable thing to only be assignable 3-arg subs?
timotimo ah 23:21
you can have a type signature for "callable that takes three arguments"
let me see if i can find the specs for you
that stuff is at least partially implemented, if not fully

heh
nbd
I can wait
I ahve lots of things to do anywya
timotimo OK :)
there's people who've spend much more time reading specs than me 23:26
frew right
if someone in here comes back and can answer I won't leave the channel
timotimo if signature-restrictions for &variables is something you're depending on for something, you'll likely get someone interested in helping you
the hardest part is sometimes getting motivated ... and sometimes finding something interested that is actually NYI
there's something else that definitely works 23:29
if you define a proto sub in your lexical scope, you can use that to restrict all signatures of lexical subs in that scope
23:34 avuserow joined
timotimo i *think* something like { my Callable[Any, Any] $foobar } should work, but neither a sub nor a pointy block seem to be doing that role 23:43
even though they probably should
colomon could this be done with a where clause? kind of hacky, but.... 23:51
timotimo yes, definitely 23:52
colomon sub wants-three-arg-function(&f where &f.args == 3) { … } # that's probably not quite right, though
timotimo i'd prefer *.args == 3 over &f.args == 3 23:53
colomon is .args the right thing to say?
colomon is trying to find example code in the spec with methods callable on Callable 23:54
timotimo probably .signature
.signature.arity and .signature.count are of interest 23:55
depending on whether or not you want to count optional args
colomon that would be it, then
timotimo++
actually, looks like you can leave off the .signature? 23:58
timotimo well, we clearly want something better than that; we want the Callable role to work and we want to know tho right syntax for giving a & variable or & argument a signature restriction
colomon m: sub wants-three-arg-function(&f where &f.arity == 3) { &f(1, 2, 3); }; sub x($a, $b, $c) { say "$a * $b == $c"; }; wants-three-arg-function(x); wants-three-arg-function(wants-three-arg-function); 23:59
