pugs_svn r24475 | particle++ | [spec] whitespace after commas is not allowed when passing multiple values to a command-line option 00:06
r24476 | wayland++ | S22 will now be just about the package format; repositories and the build
r24476 | wayland++ | process will be discussed elsewhere.
[particle] wow. two unrelated spec commits at the same time.
community++ 00:07
pugs_svn r24477 | wayland++ | Removed stuff about repositories and build and install software.
r24478 | particle++ | [spec] ideas on run-time system option and environment variables; minor updates and corrections 00:08
[particle] looks like the index for the spec website may need an update now that S22 has been renamed 00:10

mpeter what's the shebang line in windows? :D i've never used perl in windows before 00:23
jnthn mpeter: Windows pays no attention to it anyway. 00:24
mpeter hmm 00:25
lichtkind mpeter: under win there is no shebang
its association per l file ending
mpeter k 00:28
i just spent 20 minutes trying to fix a problem on a website, and it turned out that the problem was only in software that interfaced with the site 00:29
that had already been updated 3 times since i installed it >:O
jnthn OK folks, I'm going to take some sleep... Will be sketchily about for next few days. 00:31
jnthn -> bed
masak jnthn: 'night
pmichaud masak: that error is .... odd. 00:34
maybe I need to just download and compile november 00:35
masak pmichaud: that sounds like a good idea. 00:36
pmichaud: I'm pretty sure I realcleaned and built parrot/perl6 by the book before attempting to build November p6w. 00:37
pmichaud I'm building now. 00:38
yes, I get the same error.
ENOTENOUGHTESTS
okay, let's track it down :-) 00:39
masak :)
pmichaud fwiw, it might be worthwhile to use the --output=November.pir option instead of > November.pir
that way a failed compile doesn't generate an empty (and more recent) November.pir file
masak pmichaud: oh! good idea.
masak changes that 00:40
mpeter hey all you perl hackers 00:41
listen to me play "lucy in the sky"
71.192.179.132/ :D
i wrote it in tribute to larry
pmichaud looks like the problem is in Dispatcher.pm 00:42
masak I'll be mostly cheering by the sidelines during this bug hunt, because I'm struggling with a school task, due sunrise. 00:47
pmichaud no problem, I think I've got it. 00:48
I think we're not restoring all of the $?CLASS etc. variables properly on exit.
(from "use") 00:49
masak oh, ok.

eternaleye masak: You still looking for bugs? `./perl6 -e 'say map{ [ 1,2,3 ] }, ^3;'` segfaults, while p6eval doesn't 01:00

masak tests
eternaleye: no segfault over here. 01:02
eternaleye Oh, that's weird. ./perl6 --version reports 33874, while svn reports 34090
And I just recompiled 2 min ago
masak eternaleye: we discussed this earlier today, see logs about tools/rebase-rakudo.pl
eternaleye Okay, thanks
masak most of the time, I just recompile Parrot, to avoid this kind of problems. 01:03
eternaleye I did recompile parrot - make clean, Configure.pl, make world, make perl6 01:04
and `find tools -name "*rebase*"` returns nothing 01:05
Or is it in the pugs repo?
TimToady rakudo: class A { has $foo = 7; method x { say $foo } }; A.new.x

p6eval rakudo 34090: OUTPUT[7␤]
TimToady that's what it's talking about
when it says "block"
masak why would anyone use a block like that?
eternaleye Oh, it's in languages/perl6/tools/
masak eternaleye: yes, sorry if I was unclear. 01:07
TimToady dunno, but $foo is scoped to the block, and outside it you have to use $!foo, assuming that works at all
masak TimToady: oki.
TimToady which it does in places that have access to the private attr
the derived class is just returning undef for a non-existent attr, I presume
should probably have a more violent warning though 01:08
a class ought to know what its own private attrs are
and carp on a typo
masak TimToady: what should the following print?
rakudo: class A { if 0 { has $.a } }; say A.new(a => 5).a
p6eval rakudo 34090: OUTPUT[5␤] 01:09
mpeter how do you do subscripts in IRC
TimToady well, that's fine as far as it goes, but any code in there with the has is unlikely to execute
masak mpeter: how do you do subscripts over the radio? 01:10
TimToady it certainly doesn't make the attribute itself conditional
mpeter you say "subscript"
and "endsubscript"
01:10 hanekomu_ left
masak mpeter: works for me on IRC, too, then. 01:10
mpeter: or any other similar convention.
TimToady left lateral click and right lateral click :)
masak TimToady: so, in effect, 'has' statements are not deterred by conditionals, loops or other things. is that specced? can they occur mid-method? 01:11
rakudo: class A { method x { has $.a } }; say A.new( a => 5).a 01:12
p6eval rakudo 34090: OUTPUT[5␤]
TimToady well, there's no problem with putting the declaration anywhere as long as you don't rely on run-time behavior
it's just like "my" that way
masak oki. 01:13
TimToady if you say 'my $x if 0' you still get $x declared
masak aye.
TimToady it's only if you rely on 'my $x = 0 if 0' that you're in trouble
these declarations are all a bit like placeholder vars in finding some outer scope to attach the declaration to 01:14
masak that's a nice way of viewing it. 01:15
TimToady 'has $foo' just looks for two scopes, a lexical scope and a class scope
'has $.foo' only has to look for the class scope 01:16
one could argue that $^a is really short for 'param $a' or some such 01:17
masak Aristotle++ # in the latest p6l mail, using goto for good. 01:18
will Perl 6 have a goto?
mpeter did you guys like my song 01:21
use of perl 6 considered harmful 01:23
masak mpeter: I went to the page, but my browser lacked the proper plugins. I would have loved to hear your song.
TimToady masak: see S04:894 01:24
01:25 bacek__ joined
masak TimToady: oh, yes. now I remember. 01:28
from my quick reading, I conclude that Aristotle will be able to do his trick in Perl 6 also.
TimToady as my response to him indicated... 01:29
and I hope we can leave it at that :)
pmichaud r34091 should fix November. And I'm a little surprised it ever worked before. :-) 01:30
TimToady I wonder how many people realize Perl can do Duff's Device with computed goto...
pmichaud ("fix November" => "fix Rakudo so November runs again") 01:31
masak pmichaud: :)
TimToady: whoa. 01:32
TimToady [particle]: tainting is supposed to be a built-in role for every object 01:33
but it's underspecified, fer shure 01:35
one of those like-P5 things
pmichaud I like to read things like "it is specced to work correctly in Perl 6". I find more and more evidence of that every day.
01:35 stephens left
TimToady where "correctly" often means a pain in the patoot to implement 01:36
pmichaud yes, I was just looking at how we're going to handle INVARIANT: in Parrot.
TimToady the goto scan in P5 is quite spectacular 01:37
pmichaud but "Perl is all about tormenting the implementors on behalf of the users", so we're on target. :-)
TimToady we might need to special-case goto to not complain about the bareword following it... 01:38
since it can refer to a following label
masak
.oO( the waterbed theory of tormentity )
pmichaud heh.
TimToady or require a forward goto to quote the label, maybe
pmichaud "thus quoth the label, nevermore." 01:39
or something like that
time for a short break -- bbiab
masak protolabels :)
pmichaud masak: if you hear independent confirmation that November is working for others, let me know
rakudo_svn r34091 | pmichaud++ | [rakudo]: Fix handling of $?PACKAGE, @?PACKAGE, $?CLASS, @?CLASS, etc. 01:40
r34091 | pmichaud++ | These were pushing null values onto the stacks, which meant they weren't
r34091 | pmichaud++ | being restored properly on exit (as discovered by November++).
TimToady I can just see someone getting an error message: Label INVARIANT must be quoted
masak pmichaud: oki.
TimToady and saying "well, if you can figure that out, why don't you quote it yourself!!!"
masak thought the same thing 01:41
TimToady but then what if you want a computed goto to the return value of an argumentless function call?
or even not argumentless: goto somefunc() 01:42
masak what's the issue? 01:43
TimToady we can't just madly autoquote the next identifier after a goto
masak no...
check if it matches a function first?
TimToady so I'm thinking we require "goto 'INVARIANT'" unless INVARIANT is predeclared as a label
masak how do you predeclare a label? 01:44
TimToady INVARANT: establishes INVARIANT as a pseudo-type
so it can be used as a bareword afterwards
such as 'next LINE' and such
01:44 Hinrik joined
TimToady that only works because the LINE: came first 01:45
masak I guess my question is: "how do you predeclare a label without declaring it?" 01:46
as in the cases when you have the goto before the label.
TimToady you don't, you just quote the label in the goto 01:47
since we allow computed labels
masak ok.
TimToady it's easy to recognize a quoted string as immutable
so it doesn't hurt the optimizer much
Hinrik line 3425 of S05 implies that @() is interpolated in a "" string, while S02 gives me the impression that only variables and method calls/indexes on said variables interpolate, and of course {} 01:48
01:48 c9s joined
TimToady @() counts as a variable 01:48
lambdabot Maybe you meant: . ? @ bf ft id pl rc v wn
Hinrik I see 01:49

masak mpeter: I'm not sure if you're kidding, but the discussion centered around a particular problem that Aristotle aired on p6l. 01:59
it was not solvable by using functions instead of goto.

TimToady you pang? 04:49
pugs_svn r24484 | lwall++ | [STD] remove debugging statement
azawawi yes ;-)
TimToady: i think i found the bug when using STD.pm, context var emulation assumes that 'our var1' will be in main:: but that is not true when you use it in another package
TimToady yes, I run into that one periodically; usually indicates a missing :: in a $var that should be $::var 04:50
that emulation is also one of the reasons threading won't work
(I think)
azawawi TimToady: that's the only method we can do it? so threads out of the question and this bug remains also? 04:51
TimToady can you reduce it to a small test case?
there are a few other spots where I gave up on thread safety for the moment too, if I recall correctly 04:52
azawawi it is simple, package Foo { use STD; } and then use Foo; in your script
and then bless error on undefined $:PARSER in statementlist 04:53
TimToady okay, may have a chance to look at it tomorrow
azawawi cool thx
TimToady are you running your code through gimme5? 04:54
azawawi make clean all 04:55
and bundling STD.pmc, Cursor.pmc (and renamed LazyMap.pmc) in Syntax::Highlight::Perl6 (misc/Syntax-Highlight-Perl6) 04:56
TimToady but your package Foo is p6 code, so you have to translate to p5 code somehow
azawawi it is all Perl5 code im using STD.pmc
search.cpan.org/~azawawi/Syntax-Hig...t/Perl6.pm 04:57
TimToady package Foo {...} is p6 syntax 05:00

that's exactly one unit of wisdom, right there.
lichtkind masak: yes im now better informed but still clueless what mtaclasses are :) 13:08
masak lichtkind: I haven't used them much yet, since they are not implemented in Rakudo. 13:09
lichtkind masak: thats how science works, tons of infos but seldom insight

anyway, have to leave

good luck!
pmurias metaclass is the class of the metaclass instance (the thing .HOW returns) 13:12
lambdabot pmurias: You have 2 new messages. '/msg lambdabot @messages' to read them.
pmurias the metaclass instance is the thing you use for manipulating a class 13:13
masak pmurias: oh, that's true. 13:15
lichtkind pmurias: yes but i thought thats the protoobject :)
masak lichtkind: it isn't.
pmurias the protoobject is used to call methods without a real object 13:16
masak a protoobject is just an uninstantiated object. 13:17
pmurias masak: you can use metaclasses in perl5 with Moose
masak pmurias: true. haven't done that yet, though.
seems very powerful.

pmurias one confusing thing with metaclasses is that people tend to call the "metaclass instance" the metaclass 13:20
masak I guess "metaclass object" would work fine as well.
using "instance" right next to "class" feels strange. 13:21
pmurias the metaclass instance is an instance of the metaclass

well, download Rakudo and give it a spin. find something that isn't implemented. come back here and complain. submit bug reports. herd spectests. submit patches. 14:37
that's what I did. :) 14:38

cspencer according to S29, some of the math builtins are supposed to return values of Int, but they're currently returning Num's, so something like: my Int $x = floor(4.3); will fail on account of type mismatch

TimToady well, S26 is getting rewritten anyway :)

pmichaud maybe a quick note that =END isn't "real" in S26 then
eric256 i like =begin END better any way, but S26 mentions alot of POD skipping the begin part
TimToady still waiting to see what TheDamian comes up with 18:25

who's active and who's passive, and such
I think that last draft was using the notion that you always run p6 to parse, but with an option if you just want the docs 18:29
pmichaud I'm not seeing a later draft in my local archive 18:30
TimToady that's about all I remember
anyway, it's still basically in the design phase, one way or another, so don't put too much effort into the current S26 18:31
pmichaud adds a note to S26. 18:32
TimToady thanks
eric256 i just wanted __END__ to comment out a bunch of code (debug from the bottom up) so i implemented it localy
TimToady there is no __END__ anyore
*anymore
it's just =begin END

cspencer i'm trying to add some methods written in perl 6 to one of the builtin classes, but the "is also" seems to cause subroutine parameters to be correctly scoped 21:17
is this a known issue at the moment? 21:18
pmichaud yes
cspencer alrighty
pmichaud we don't have "builtins in perl 6" working quite yet.
cspencer ah ok
pmichaud it's high on my list of things to do.
but I've got to clean up class construction first, as you've noticed.
and we need to refactor parameter handling.
cspencer sure, ok :) i'd seen a ticket where you'd suggested implementing pick() is p6 and had taken a stab at it 21:19
as well as splice() in the process
pmichaud can go ahead and submit it to rakudo bug as a proposed patch. 21:20

cspencer it seems to only happen when declared in list syntax

pmichaud correct, it only happens in list syntax.
The list syntax handler is overriding the default for @a with its own idea that it should be Undef.

cspencer i'm going to take a wild guess and assume that the error thrown when an optional parameter is declared, but no default value is provided is also part of the coming refactoring? :) 22:03
ie
rakudo: sub foo (Int $size?) { say "bar" }; foo();
p6eval rakudo 34116: OUTPUT[Parameter type check failed in call to foo␤current instr.: 'die' pc 14378 (src/builtins/control.pir:188)␤]

plan was get STD_blue+rx_on_re passing rx_on_re tests, then either work on rx t/ files, or start in on running STD.pm . but STD.pm support for p5 re turns out to be a bit broken. so... not sure. 22:51
22:53 thepler left
mncharity answering question by looking backwards instead, have misc/elfish/rx_on_re make check_blue running, which is the rx_on_re test suite with the regex tests passed through STD_blue (ie, through STD.pm+gimme5), into elf IR, emitted to p5, and run. 22:54

mncharity the p5 portion of the test suite is obviously more valid that the somewhat out of date p6 rx portion. and has more >95% passing. so I was going to use that to shake everthing down hard. but the STD.pm p5 re parsing turns out to need some more work. I was finding slow and very non -Ofun going. :/ Anyone want to work on STD.pm? I can give a list of parsefailing regexps.

pmurias mncharity: how would parsing p5 regexes better help the bootstrap 23:01
?
TimToady mncharity: I think your problem must be in somewhere in the P5Regex code--are you in sync with svn head?
assuming you have some custom code in there, likely you are doing something that is giving fooling gimme5 into emitting bad code 23:03
gimme5 is rather picky about the code it will translate 23:04
I give it about a 50% shot that you need to double the curlies in some closure somewhere to avoid confusing gimme5

TimToady one of my goals was to replace gimme5 with viv, but haven't got back to that 23:05
mncharity drat. ok, I rm -rf perl6; svn up'ed; and make works. :( so I through away to ability to experiment with what make distclean wasn't cleaning that rm -rf did. sorry about that. upside is I'm working now (re make). 23:06
re p5re,
$ ./try5 comp_unit -e '/:P5 (?!a)/' Parse failed. See try5.err. 23:07
$ ./try5 comp_unit -e '/:P5 (?i:a)/' Parse failed. See try5.err.
$ ./try5 comp_unit -e '/:P5 ()\1/' Parse failed. See try5.err. 23:08
moritz_ is the :P5 modifier even legal inside a rule?
avar isn't the modifier supposed to be outside the pattern/
moritz_ ./try5 comp_unit -e 'rx:P5/(?i:a)/' # win! 23:09
mncharity re :P5, I note it's sufficient to get me into the STD.pm P5Regex grammar. other than that, no idea.
moritz_ same with rx:P5/()\1/ 23:10
mncharity ok, that's unexpected. I have m:P5/.../ logged as not working at all. 23:11
moritz_ tries to give mncharity some hope back 23:12
TimToady the Regex grammar does define :P5 as an internal modifier, but it could well be messing up the linguistic handshake somehow

eric256 yea. but is that a workaround or the way its going to be? 23:14
TimToady actually m/:P5 xxx/ works fine, so it's probably just missing P5Regex stuff
actually, m:P5// only works because it's parsing the // as a string 23:15
pmichaud eric256: .map should work on Range -- the problem is that the '.map' method needs to move to Any
TimToady it doesn't actually call into P5Regex correctly
pmichaud I think right now it's defined in List, which isn't (completely) correct.
eric256 ahh okay
moritz_ notes that we need more tests
pmichaud stated slightly differently: .map is defined in src/classes/List.pir, but it needs to be in src/builtins/any-list.pir
eric256 is porting perlmonks.org/?node_id=731651 to perl6 for fun 23:16
is it as simple as cut & paste ? cause i can do that and test and right tests if so
pmichaud if someone wants to move the map definition from List.pir to any-list.pir, that'd be a worthy patch.
TimToady there's a sense in which parsing // as a string is more P5ish though
pmichaud it's not _quite_ cut & paste.
TimToady and it should only be fed to the P5Regex parser after interpolation, but maybe that's going to far in accommodating P5 semantics... 23:17
eric256 okay, i'll add it to my list
TimToady s/to/too/
pmichaud eric256: also, you might submit it as a rakudobug. That will at least remind me it needs to be done. 23:18
mncharity sorry, got sucked into analysis. moritz_: re hope, yes, much appreciated, thanks. re string, yeah, rx:P5/foo/ is regrettably not actually parsing the p5 re. 23:19
TimToady but that is how the P5 lexer does it, alas
well, with some preprocessing knowing it's really a regex
but it's all a big hairy kludge in p5 23:20
mncharity /:P5 foo/ *is* parsing the p5 re, but yes, it's not entirely working.
TimToady not clear how much :P5 wants to emulate that
also not clear if external :P5 and internal :P5 need to do it the same way :)
mncharity lol sigh 23:21
pugs_svn r24505 | moritz++ | [t/spec] a test for Range.map
TimToady arguably it might be correct the way it is, and external :P5 should interpolate and then call P5Regex on the result
and internal :P5 remains blissfully ignorant of interpolation 23:22
moritz_ calls it a day, TTFN folks
TimToady ciao
mncharity moritz_: thanks again

mncharity the rx:P5/I am a string, call P5Regex to parse me at compile or runtime/ story sounds plausible. 23:32
but still leaves me with a only partially working STD-based p5 re parser. 23:33

23:39 donaldh left
mncharity "how would parsing p5 regexes better help the bootstrap", there's a solid p5 re test suite. absent that, there indeed wouldn't be much point. it permits robust incremental development. 23:39
23:40 c9s left, hercynium joined
mncharity test driven, keep-it-working development. "the p5 library passes the tests, then the p6-ified elf-ification of that library passes the tests, then using STD_blue for parsing passes the tests (and keeps them passing through STD.pm changes and syncronizing with STD/current dialect p6 rx), then STD-running-on-elf passes the tests". 23:42
well, solid is overstating it. there's a quite partial but still non-trivial p5 re test suite. compared to the complexity of p5 re, the perl5 test suite could use several 100% expansion. but... beats nothing. 23:45
eric256 its kinda surprising but perl6 does still feel like perl5 when you get right down to coding in it ;) and its worth it just to get real parameters for subs ;) 23:46
mncharity lol :)
eric256 perlmonks.org/?node_id=731696 can someone check that out and see if i missed any easy advantages? only gained like 4 lines on the perl5 implementation, doesn't seem like enough 23:47
hehe
mncharity looking
eric256 oh and rand feels klunky, looking for some specs on it now

eric256 i think part of what threw me off was rand suddenly returning 0 23:51
mncharity @weights.int seems odd. hmm, a good exercise might be to try writing it in idiomatic somethingelse. ruby or python. and then translate back to p6. 23:52
lambdabot Unknown command, try @list
eric256 yea whats a good way to get the length of an array in p6? .int works but maybe isn't the prettiest ;)

eric256 hey, with .clone implemented shouldn't (is copy) just do a clone? 23:55
eric256 guesses that probably is in the refactoring that he keeps hearing about 23:56
