b7j0c any idea why i see "No rule to make target `/home/sergej/community.cvs/devel/parrot/src/parrot-1.0.0/parrot', needed by `perl6_s1.pbc'" when trying to build rakudo from git?? 04:50
skids did you perl Configure.pl --gen-parrot?

b7j0c and i have never downloaded rakudo from git before tonight
skids You should let rakudo checkout and build it's own parrot, it's still lockstep with particular parrot versions.
b7j0c but why is "sergej" being hardcoded in a Makefile? why would building my own parrot address that? 04:56
skids That should have been done when you ran Configure.pl with --gen-parrot, though
pyrimidine I just built rakudo today from the latest parrot (seemed fine)
b7j0c well i will uninstall the arch linux parrot and try again
skids Makefil should be autgen, not hardcoded 04:57
You shouldn't have to uninstall.
b7j0c oh, the git version needs subversion (?) 04:58
skids Yeah parrot is still svn.
b7j0c ok getting that too...

pyrimidine type constraints shouldn't require 'of' 05:02
skids Well, definitely not on simple decls. Checking docs now about param decs.
pyrimidine doing same... 05:03
b7j0c strange...after blowing away arch's parrot, building seems fine. harumph. let me guess, i am the only one other that 'sergej' to try it. anywho, what can we do with rakudo today? i dropped out of p6 around the pugs era, interested to know what state it is in 05:04

skids now for the unfun part, searching RT :-/ 05:09
pyrimidine This is fairly recent (within the last week or two). 05:10
found it: github.com/rakudo/rakudo/commit/fb5...b799c405ef
05:11 b7j0c left
pyrimidine so, this now works with .of (but breaks constraints otherwise) 05:12
skids 58278, closed ticket, jnthn mentions it at the end. If I don't find another, maybe re-open that ticket.
Yeah typed array support is new. 05:15
pmichaud Are slurpies allowed to have type constraints? 05:16
skids rakudo: class X {}; class Y {method a (X @a) { say 1} }; Y.new.a([X.new]); 05:17
p6eval rakudo f2c582: OUTPUT«Non-Positional argument or Positional of wrong element type for @a in call to a␤current instr.: 'die' pc 17324 (src/builtins/control.pir:222)␤»
skids rakudo: class X {}; class Y {method a (@a of X) { say 1} }; Y.new.a([X.new]);
p6eval rakudo f2c582: OUTPUT«1␤»
skids ok not unique to slurpy
pyrimidine yes, found that as well 05:18
pmichaud I'm not sure that [X.new] has Positional[X]
i.e., I'm not sure that we dynamically check all of the elements of a list to make sure they're type compatible when doing a bind of a Positional[Any]. 05:19
(or just Positional)
pyrimidine this did work at one point (but that doesn't mean it's correct)
pmichaud you mean it worked at one point in Rakudo?
pyrimidine yes 05:20
pmichaud I suspect it's just that Rakudo wasn't doing type constraints.
(on arrays)
pyrimidine yes
pmichaud I guess I'll ask jnthn/TimToady about it a bit later today. 05:21
pyrimidine It may be a spec issue (nothing is mentioned about it re: arrays or hashes) 05:22
and .of seems to work
rakudo: class X {}; class Y {method a (@a of X) { say 1} }; Y.new.a(X.new);
pmichaud rakudo: say [X.new].of
p6eval rakudo f2c582: OUTPUT«Non-Positional argument or Positional of wrong element type for @a in call to a␤current instr.: 'die' pc 17324 (src/builtins/control.pir:222)␤» 05:23
rakudo f2c582: OUTPUT«Could not find non-existent sub X␤current instr.: '_block14' pc 53 (EVAL_16:37)␤»
pmichaud it may be that 'of X' simply isn't doing the type constraint either.
pyrimidine rakudo: class X {}; class Y {method a (*@a of X) { say 1} }; Y.new.a(X.new);
p6eval rakudo f2c582: OUTPUT«1␤»
pyrimidine ding!
pmichaud rakudo: class X {}; sub foo(@a of X) { say 1 }; foo([Int.new]); 05:24

skids rakudo: class X {}; class Y {method a (*@a of X) { say 1} }; Y.new.a(3);
p6eval rakudo f2c582: OUTPUT«1␤»
skids yeah of is a noop.
pyrimidine okay, makes sense. I'll hold off on the bug report until jonathan/TImToady is asked 05:27
pyrimidine sleep
pmichaud it's okay to file the bug report so it's not forgotten :-) 05:28
or you can wait.
pyrimidine ok
05:28 Kisu left
pmichaud I'm just curious what the answer will be :-) 05:28
skids And there seems to be none that touches it yet.
(no RT ticket at least)
05:28 Kisu joined
pyrimidine well, it's either a bug or a spec issue that needs clarification (or both) 05:29
so to RT I go
(or rakudobug)
skids spec issues can go in RT, that's fine.
Tene pmichaud: any idea on the 'right' way to define subs that have unusual names?
pmichaud: right now I'm just using hash access on the namespace. 05:30

pmichaud Tene: you mean in Perl 6? I think that's the normal way to do it. 05:59
Tene Hmm. Okay.
pmichaud If I don't get too distracted with other things, I'm thinking of hacking in support for custom ops this weekend. 06:00
Tene In this specific case, I was looking at defining additional sub traits, which in rakudo means defining a '!sub_trait_foo' sub
I don't know how that's specced to be done.
pmichaud in the general case, they're just roles, I think. 06:01
06:01 eternaleye left, skids left
pmichaud the reason we have !sub_trait_foo in place now is because we either want to optimize that particular trait or our implementation of roles isn't quite up to the task yet. 06:02

masak heh. the students here did a quick round of introductions. the more known you are, the less you need to say. I talked for a minute I think. pmichaud said "I'm pmichaud, the lead developer for Rakudo, the Perl 6 impl on Parrot. And that's all you need to know". TimToady said "I'm Larry". :) 07:41
omega haha :p
07:43 mberends joined

jnthn OH NOES
TimToady depends on how the buffering works
masak oh, true.
TimToady and the implementation of say
jnthn I've had an alarm clock usage fail...
TimToady I would not expect say to do a join 07:55
07:55 KyLe48 joined
masak TimToady: the stringification of 1..* might. 07:55
baest jnthn: you're sure it wasn't a whiskey fail? :)
jnthn Say calls $*OUT.say with the args I guess...
baest: I assure you the whisky was a win...
TimToady if it's implement by just fprintfing each value, then flushing on newline, you'll still get intermediate results
when the buffer fills
07:55 mib_i7k0dt left
TimToady it's likely the stringificaiton of 1..* will "go meta" 07:56

method add (Array @rules) {
08:20 pnu joined
omega does that mean an array of Arrays? 08:20
pmichaud it does. 08:21
masak omega: yes.
omega: is it Dispatcher code?
er, Dispatch.
omega masak: no, I fixed Dispatcher now
working on Tags failure
jnthn Rakudo only started enforcing that this means a Positional of Array recently. 08:22
masak great.
omega so if I want an Array of Str, it woul be method add (Str @array)?
masak aye.
we should really rename Tags to November::Tags.
jnthn omega: Yes, ish, but note that really you're asking for a Positional of Str
Where Positional is a role that Array happens to do (but also List, etc)
omega but I guess I don't really care if its Array or List? 08:23
masak no.
jnthn Right, which is why there's a Positional role. ;-)
omega :)
jnthn Anyone know if it was possible to buy the tram tickets on the tram with card, or must I go find cash first? 08:24
omega you can stop by 7-11 for instance, and get a tram ticket there
mberends or you can walk like we did ;)

pmichaud masak: yes, some older issues are still in RT and haven't been migrated to Trac yet.

wayland76 mberends: But if we all took that attitude, S17 would never be ready :)
masak wayland76: I'm not sure I agree. 09:22
wayland76: application code tends to drive the spec forward, as well.
wayland76 masak: In detail, yes, but in something as large as S17?
pmichaud I think there's a trac ticket for that. At any rate, the parrot tickets are slowly being migrated.
I can't find an RT ticket that describes capturing stream output from subprocesses, though. Perhaps it wasn't a ticket. Perhaps it got inadvertently closed. 09:23
so, perhaps just file a new trac ticket (and someone else can figure out if it's a duplicate :-)
wayland76 masak: And I'm assuming the drive sequence is app code ==> implementation(rakudo, etc) ==> Spec
masak pmichaud: I'll file the ticket, but primarily I want to write a good email to parrot-dev.

baest wonders why length is banned in perl6 but welcome in parrot :)
masak cosimo++ 12:18
baest: well, one explanation is that the Parrot API congealed before the Perl 6 API did.
baest: another is that whereas Perl 6 is sort of restricted to conform to the regulations of Perl 6, Parrot isn't. :) 12:19
baest make sense, I was mostly failing in being funny :)
masak baest: I have a bad habit. I answer seriously to people being funny. 12:20
baest masak: but still, the same argument in Perl6 should apply to Parrot
masak that way, I don't look bad if it turns out they were actually being serious. :)
baest: it could, yes.
baest: but the fact remains that Parrot is not ruled by Perl 6 design concerns. not in that sense anyway. 12:21

LylePerl I've been learning some parrot to try and figure the best way to write tests for chdir
I came across docs.parrot.org/parrot/latest/html/...s.pmc.html
masak well, there you go.
LylePerl So have been temped to write and spec for mkdir as well and have a go at implementing those 12:36
(I'm guessing it should be easy as it sits on top of the parrot ops)
to test chdir, I need a cwd
I can't find cwd mentioned anywhere in the docs 12:37
I could just drop down to parrot in the test, but perl 6 is going to need some kind of cwd
perl6: $*CWD.say
p6eval rakudo 341f44: OUTPUT«Use of uninitialized value␤␤»
..elf 26258, pugs: OUTPUT«␤»
baest LylePerl: there is a STRING *cwd() in STRING *cwd() 12:38
masak buubot: spack cwd
buubot masak: Sorry, I couldn't find any matches for: cwd
baest sorry in docs.parrot.org/parrot/latest/html/...s.pmc.html
LylePerl PUGS $*CWD.say works for me locally
baest: I know 12:39
baest cwd is a method
LylePerl perl 5 doesn't have a cwd built in, but has Cwd.pm 12:40
I was hoping TimToady might give a pointer as to how he wants to deal with this since $*CWD has been dropped 12:41
masak LylePerl: what, specifically, is it that you'd like to have clarified? 12:42
LylePerl How to get current working directory in perl 6
whether a method should be implemented, or a variable or an object 12:43
I know that time this came up he mentioned a $CD object or something
masak hm.
there's an OS class in S29.
but maybe that's not the right place to put it, because it's not the OS that's changing directories, it's the program context. 12:44
LylePerl S29 doesn't mention any cwd though
masak LylePerl: right, none of the specs do.
LylePerl That's why I haven't implemented the tests, I wanted to know which way this was going first 12:45
on Linux you can just grab the PWD Env, but that isn't portable
masak sure. :) just don't expect that someone will necessarily come forward and tell you.
12:46 Psyche^ joined, Psyche^ is now known as Patterner
masak the usual way this happens is that someone commits a draft-like suggestion, and people say "yes, that's fine" or "no, that's not so good". 12:46
LylePerl Ok. I'll bite the bullet and put some more suggests in the spec 12:47
masak if you create a new class DirectoryChanger with the sole method cwd, that would at least create some debate. :P
12:48 Whiteknight joined
LylePerl I thought maybe add it to IO::DirectoryNode? 12:49
wayland76 How about IO::FileSystem?
TimToady LylePerl: whatever we come up with has to support both one current dir for the whole process (Unix model) or a separate current directory for any dynamic scope that overrides the current directory, which supports things like an apache server running independent threads 12:50
pnu multi sub based on return value type .. NYI or not specd?
TimToady the latter has to have some support from with IO, of course
wayland76 At onepoint, Tree was going to handle this, but Tree got scrapped :) 12:51
TimToady specced as not necessary for 6.0
jnthn And as a result not implemented. ;-)
masak pnu: you can do it already with 'where' clauses.
std: *\i
p6eval std 26258: OUTPUT«ok 00:02 35m␤»
TimToady LylePerl: another design point is that the same interface should work for both cases, so that you can incorporate a standalone script in a server 12:52
jnthn That is provided you mean multi x() returns Int { } and multi x() returns Str { } and expect them to differentiate on the return type of that multi.
wayland76 Can you believe my NetBook didn't have the Perl documentation installed? :)
pnu jnthn: yes, based on the callers context.. where i'm putting the return value. 12:53
LylePerl TimToady: I assume the cwd from parrot of PMC is for the whole process... And the dynamic one would have to be implemented differently?
TimToady $*CWD (or whatever name we end up with) is a contextual variable, so can be overridden in a dynamic scope 12:54
so separate threads could have different wds
at a fundamental level we're trying to get the same abstract separation that Unix processes get, only between threads 12:55
and contextual variables are really modelled on env vars
(except we can have rw ones)
where any child can write
so such a variable would have to have locking 12:56
wayland76 Have we taken into account that Windows systems have a separate CWD for each drive?
TimToady no
masak should we?
TimToady I am dubious :) 12:57
LylePerl If the script has only one $*CWD I wouldn't have thought it mattered
switching drives in the $*CWD would just adjust that individual drives cwd 12:58
12:58 DemoFreak joined
LylePerl You wouldn't be pointing to the old one so it's CWD wouldn't matter 12:58
(i think) :s
TimToady I know folks would would say "You're using Windows, so it wouldn't matter." :P 12:59
pmichaud (length in parrot): It's also useful to remember that Parrot's original target wasn't really Perl 6, but rather a "best guess" at what Perl 6 might be like given the current knowledge of Perl 5.
TimToady *who would
pmichaud So in many ways, Parrot targets Perl 5 more than Perl 6. :-|
TimToady how do we then explain that Parrot runs Perl 6 better than it runs Perl 5? :) 13:00

TimToady but you can't put in {} either, since

I understand more PIR than I did this summer, but not as much as I'd like.

16:16 iblechbot joined
skids scook0: autothreading means that MP is not guaranteed, but MP might occur. 16:17
but in any case functionally when there's no chance for MP inconsistency it reduces to just distributing the operation. 16:18
The take away is that you shouldn't expect side effects to work well.
scook0 yeah, I'm just having an Internet Argument about whether the term "autothreading" in P6 refers specifically to the distribution or the parallelism 16:20
back when I was involved it was always about the distribution
skids Mostly to the distribution, but with parallelism caveats. e.g. (1,2).>>say might say "2 1" 16:21
But then with junctions order is not guaranteed in the first place. 16:22
16:24 xinming left
skids Most importantly with junction is side effects. e.g. my $j = 1|2|3|4; rot(@a, $j); where rot is something like @a[0,1,2] = @a[2,0,1]; might wind you up with unexpected results. 16:24

masak jnthn: I think we're slightly more ambitious than you are over here.
skids By OK I mean would pmichaud take it :-)
jnthn masak: Ambition FTW. :-) 17:44
pmichaud it's not only the proto that would have to change
we'd also have to be able to correctly handle semilist args 17:45
skids right but once that was done, just change the proto on the implementation I mean.
pmichaud I guess I don't quite understand what zip/roundrobin would do then.
skids Until slice/semilist you'd have to invoke it as zip([\@a,\@b,\@c]) 17:46
pmichaud if you create it as a slurpy argument, then zip(\@a, \@b, \@c) would work. 17:47
skids Right, so it would be there, but different than the spec zip(@a;@b) until slices, would that be OK?
Then at least the body is done and just needs to be tweaked. 17:48
pmichaud I guess I'm okay with that. We might want to call it something slightly tweaked from zip() though.
so that it's extra-clear that it's not the official zip.
skids OK. 17:49
skids wants roundrobin renamed to "whip" anyway :-)
