ian__ now that the stable release is 5.12.0, what's the preview release, if any? 00:08
lue erm, are you talking about Perl 5 ? 00:09
daemon hey guys, im going to install perl6. however according to ports perl6 does not exist, would 'pugs' be correct? 00:11
cognominal no, pugs is obsolete.
daemon mail# pwd && ls | grep -i perl6 00:12
/usr/ports/lang
p5-Perl6-Subs
pugs/pkg-descr says:
Pugs is an implementation of Perl 6, written in Haskell.
.. I won't paste the rest
lue try rakudo. Go to perl6.org . Rakudo is the one being kept up to date. 00:13

lue hello snarkyboojum :) 00:14
daemon Path: /usr/ports/lang/rakudo
Info: The Rakudo Perl 6 Compiler targets the Parrot Virtual Machine
there it is
thank you again ^_^
quester_ daemon: Careful! Rakudo is in early development and changing _very_ rapidly. You probably want to get the source directly from github.com. 00:15
daemon: For example, there was a major change to the compiler internals two months ago. 00:16
00:17 jhuni joined
quester_ daemon: See rakudo.org/how-to-get-rakudo for general instructions. 00:17
daemon quester_, advice taken ill give it a whirl in a virtual box - I try my best not to use sources unless I absolutely can't avoid it ^_^
quester_, hehe 00:18
for free it tells me to just pkg_add -rv
or use ports
[particle] preliminary gsoc slot count for tpf: 10 00:19
quester_ daemon: I see your point, but using Rakudo at all involves... a certain amount of trust. I have only ever run it in virtual machines. Keep in mind that Rakudo may be a year or thereabouts away from what would normally be termed "release 1.0".
daemon quester_, gotcha well I use perl5 alot... so lets see how perl6 handles, will I need brandy or whisky for he first run? 00:20
00:21 snarkyboojum left
quester_ Even if there is no malicious intent in any of the code, you may things that have never been tested, and get interesting results. (Bug reports are very welcome.) 00:21
Vodka?
daemon can get that too :)
quester_ s/may/may do/ 00:22
daemon I suppose it cannot be any worse than the first time I found out about POE and gave that a go 00:23
turned out to be one of the most handy things I ever did learn
dngor is a genius
frooh s1n: where you at yo? 00:24
00:24 lichtkind joined
lichtkind hej 00:25
quester_ daemon: Yes... but keep in mind that Rakudo and Parrot are both in the very middle of being written. You may bug where no man has bugged before.
lue hello o/

daemon quester_, that just adds to the fun :)
lue from vacation? I noticed a wiki-man was missing... :)

had an resolving disk
lue resolving?
lue thinks you meant revolving... 00:28

diakopter as the grammar becomes larger, the stage0 compilation step takes noticeably longer.
(as well it should; it's quite complex) 02:07
here's the diff, in case you're curious. code.google.com/p/csmeta/source/detail?r=127# 02:08
once it starts taking longer than 3 seconds, I'll start precompiling/disasssembling/snapshotting the grammar into perlesque itself so that it doesn't have to build stage0 upon every execution. 02:11

thowe how does one check perl 5 for thread support? 03:26
sorear perldoc Config
every Perl 5 installation contains a Config.pm module, which exports a hash of all values provided to or detected by Configure 03:27
executable file extension, word sizes, debugging flags, threads, search paths, everything
thowe Hmm. No Padre for me.. 03:28
sorear oh, you meant on the command line?
cognominal perl -V:useitheads ?
thowe Yeah, but I ran the code fragment.
sorear perl -V:useithreads
thowe I'm currently on a FreeBSD 8.0 box. It's actually pissing me off. Gonna go back to OpenBSD. 03:29
I think gnome-terminal is my best bet for Perl 6 on there.
sorear don't check 'usethreads'; that refers to 5.005 threads, which were broken by design, deprecated in 5.6 or 5.8, removed from the default configuration in 5.8 or 5.10, and removed from the code entirely in 5.12
I'm suprised Padre uses threads 03:30
thowe FreeBSD doesn't have threads by default. If I built Perl special I could hav eincluded them
It's apparently made a big deal of in the install instructions
sorear oh wow, progressive
perl 5 threads are universally hated
most OS perls have them, and the first thing you're supposed to do as a serious Perl user is compile a custom perl with them disabled 03:31
thowe Huh. Probably why disabled in default FreeBSD port. OpenBSD comes with perl as part of the base system, so I'll bet they are also disabled. Especially since rthreads in OpenBSD are still not there. 03:32
sorear the root problem is that the perl 5 data core has no real encapsulation 03:33
5005threads put a mutex on every scalar
thowe Is there a list of Perl6 software projects anywhere? It would be interesting for me to take a look.
sorear but they're crashy because there's no central place to add locking code 03:34
and so it was added everywhere - didn't work so well
ithreads are based on the 'perlfork' 5.6.0 Windows fork() emulation
they consist of duplicating (no COW here) the entire interpreter heap and all global variables 03:35
if you need parallelism and relatively cheap "IPC", they're good
but they're really quite a niche tool
and, because they have to pass around a Perl_Interpreter * object (no global variables in a threaded world), they have a noticable single-thread penalty 03:36
on the order of 10% runtime
thowe: maybe github.com/masak/proto/raw/e2c8ed1e...jects.list 03:37
thowe hm
sorear there's also gitorious.org/parrot-plumage/parrot...r/metadata 03:40
and a lot of stuff still lives in the pugs repo
(but not pugs)
thowe pugs?
sorear audreyt's Perl6 compiler
it was the first major implementation
hosted in SVN with free commit bits to all, it effectively was Perl6Forge for the first couple years of perl6's existance 03:41
thowe cool

snarkyboojum sorear: you noticed some issues with the perl6book?
sorear yes
but I don't know how to fix them 05:08
if anything, it's probably a Pod::PseudoPod::LaTeX bug
untranslated B<> is showing up in the .tex
snarkyboojum sorear: oic which file?
sorear and pdflatex, for some insane reason, renders unquoted <> as ¿ and ¡
snarkyboojum: build/book.tex
snarkyboojum sorear: could be, I came across some similar bugs a while back 05:09
sorear anywhere in the .pod where nested inline markup is used
e.g. I<<oscilloscoB<pe l>acks precision>>
from regexes
snarkyboojum ah - I don't have pdflatex tools installed on OS X
sorear are you just viewing the pod raw? 05:10
snarkyboojum yeah, or generate the html
which has it's own issues (embedding images etc)
its 05:11
sorear there are a couple places where verbatim blocks aren't and code has gotten turned into flow paragraphs
I didn't make note of where though
(for 50 pages of stuff I already know, that was a remarkably slow read)

snarkyboojum curiously when trying that via ./perl6 --target=parse I get the following error
'Method 'symbol' not found for invocant of class 'Undef''
sorear what does subset with no where mean?
snarkyboojum no idea, but should it parse? 05:27

it turns out that initial whitespaces are required even in "programlisting" blocks. Reported by sorear++

moritz_ aye, I've learned that recently, but it needs time to sink in
masak *nod*
moritz_ looking at the access logs of my websites, I find a nice correlation between visitor counts and new blog entries 08:41
on the day of publishing and the following day, I have about 80 to 150 more visitors than on comparable weekdays without new posts
masak an incentive to blog :) 08:42
moritz_ and on the second day after publishing it's typically still 50 more
aye
when I know that people actually read what I write, I'm more motivated
when I started blogging I read lots of jokes that most blogs have between 0 and 1 reader, and it felt that way too 08:43
I guess writing that 5-to-6 blog series changed that :-)

mathw that's inevitable I suppose
masak that's part of the Perl 6 discourse. 09:40
jnthn Got some nice one about threading. "Is Rakudo * too early?"
masak as an idea, I think Rakudo * could have been a lot earlier.
on the other hand, it will always be too early in the sense of important RT tickets not having been fixed yet. 09:41
it's all a matter of prioritizing.
mathw aargh threading 09:42
mathw is currently wrestling with a horrible object encapsulation/multithreading problem
09:42 pausenclown joined
moritz_ would rather see no support for concurrency at all than crappy threading 09:42
mathw well, Parrot needs nice threading first
although we could have the design all done before then of course 09:43
masak fsvo 'all done'
mathw only thing I know about threading is how not to do it though
masak: obviously it's informed by implementation, so it couldn't be 'complete'
moritz_ mathw: there's a gsoc proposal for fixing up threading iin parrot
mathw moritz_: yay!
I'll cross my fingers for that being accepted
at the moment my biggest thing about threading is 'don't do it in a language which is oblivious to it' 09:44
moritz_ the chances aren't bad
mathw or maybe 'don't share memory by default'
I'm not sure if that's good in general or not, it probably kills your performance in some scenarios
but it would save me a lot of trouble
09:45 araujo joined
moritz_ I kinda expect to see different concurrency systems emerging in the future 09:45
some which are aimed primarily at speed
and other primarily aimed at ease of use, even if that means that some scenarios can't be implemented efficiently 09:46
mathw that'd be nice
rather than trying to ram everyone into one model that doesn't work for any of them very well 09:47
actually a lot of my pain right now would go away if we had re-entrant locks
it's like the design was done for re-entrant locks, and then someone realised they're not re-entrant
jnthn Yeah, it's...hard to get concurrency right. It cerainly needs to be informed by implementations *and* user feedback. 09:48
mathw I believe it to be one of the hardest and most important problems in programming at the moment 09:49
09:49 alester left
arnsholt mathw: I agree 09:49
For inspiration, Haskell and Erlang's threading implementations might be useful?
09:49 _newbie3 joined
mathw which one of Haskell's? :) 09:50
jnthn Probably we need to make sure we allow enough flexibility to let more than one way to be implemented.
mathw I know STM's been talked about for Perl 6
jnthn Since there's more than one type of parallelism.
mathw but I believe that has been shown to have some nasty drawbacks in some cases
arnsholt Haskell has optimistic locking or whatever it's called, IIRC
jnthn (data vs task, for example)
mathw jnthn: yes
precisely why having one model of concurrency breaks down
jnthn TMTOWTDI.
mathw but it can be just as bad having no model, if the programmers using the system don't then decide on the appropriate one and stick to it 09:51
jnthn It's be kinda unperlish to force one model.
mathw giving people a thread class and a semaphore or mutex is just asking for trouble - but you also have to make the primitives available so that new models can be implemented, even if you'd rather people didn't use them directly
arnsholt I think the reason STM works so well for Haskell is that it's a strategy for situations with many reads and few writes. Which fits nicely with purely functional =) 09:52
mathw yeah
jnthn arnsholt: Good point.
mathw plus if your core computation in any transaction is pure, your re-roll could be quite cheap if there's a conflict
that is, if the system can see that your inputs didn't change
arnsholt Yeah
mathw I always wanted to play around with a system where threads talk to each other by pushing things onto message queues 09:53
jnthn looks forward to play with concurrency bits
arnsholt mathw: IIRC that's how Erlang works. Message passing
mathw I've got some plans for investigating these things at work, but unfortunately if I do that it brings it under corporate confidentiality. 09:54
arnsholt: yes, and it's fairly agnostic about if you're talking ot a thread or a process or another computer I believe
09:54 _newbie3 is now known as jaffa4
arnsholt Yeah, I can imagine that being an upshot of implementing message passing right 09:55
mathw message passing has to be coupled with no shared memory by default
I think
if you do that you can certainly spread yourself across a network fairly trivially
moritz_ fsvo trivial :-) 09:56
mathw I'd think Perl 6 could probably be taught to support that model :)
moritz_: well most of the mess would be in the library, not your program :)
isn't our philosophy one of torturing the compiler writers for the sake of the users? :)
masak CokeBot9000: I had 'Any' instead of 'PokerHand' in some places was due to rt.perl.org/rt3/Ticket/Display.html?id=74352
s/was //
arnsholt mathw: Yeah, that's one of the things that appeals to me with message passing. No shared memory means no weird races there 09:57
moritz_ you still get weird races that are inherent to concurrency 09:58
but less
masak how was last night's #rs, by the way?
moritz_ not very productive
I had to run off after a few minutes
at least it's a short read in the logs :-)
masak oh, logs! 09:59
masak reads them
mathw arnsholt: there's a certain architectural elegance to it. I also like the idea of writing an entire system on the basis of a global queue of 'things to do' and a pool of threads which consumes it 10:01
I'm going to try that one day and see what kind of messes it produces
masak CokeBot9000: ah, I see that you fixed that by transforming 'A & B' to '{ A && B }' instead. cunning.
...though probably wrong... :/
rakudo: subset A of Any; say my $a ~~ A 10:02

masak CokeBot9000: that block will never match. type objects boolify to False. 10:03
masak writes it as explicit smartmatches on $_ instead
bacek ~~ 10:07
jnthn, aloha. In which timezone are you now?
masak CokeBot9000: the reason '&' worked was that the junction delegated to type matching on the subtypes. but the block nullifies the effect of being in 'where' position, and the subtypes are instead boolified by the '&&' 10:09
or not exactly boolified, but treated as truth values of some sort...
moritz_ isn't that the same? :-)
masak there might be a slight technical difference. 10:10
in boolification, it's actually turned into an actual Bool. 10:11
in being treated as a truth value, it's not coerced, but being treated as if it were True of False.
mathw True of False, now there's a mind-bending concept
moritz_ but 2 is neither True nor False
masak that's the difference between ?& and &&, respectively.
mathw: oops. :)
moritz_: no, but it boolifies to True, and && will treat it as a true value. 10:12
moritz_ and ?& will not?
masak yes, but only after turning the 2 into True. 10:13
&& won't do that.
it's visible when the rhs is actually returned from &&.
er, the right operand.
moritz_ but both && and ?& treat the left operand the same, right? 10:14
masak inasmuch as you can't detect the difference, yes :)
moritz_ rakudo: say 1 ?& 2 10:15
p6eval rakudo aae95f: OUTPUT«1␤»

and I don't mean S19 as much as simple things.
-I, -n, -p, -i 11:10
just get it all right once and for all.
Juerd Is there a definition of right?
masak that would be awesome.
Juerd Or would inventing what's right be part of the task?
masak Juerd: first approximation: as the 'perl' executable does it.
no inventing or investigating. JDFI. :) 11:11
Juerd Just do fucking it?
masak Just Ducking Foo It. :)
cognominal yea, and lexical variables not going out of scope at each newline in interactive mode. This is my pet peeve
masak cognominal: tell me about it.
cognominal: but IIUC pmichaud was well on his way to fix that.
Juerd fails to care about interactive mode at all 11:12
I've never felt the need for a repl, other than for simple calculations, as in perl -ple'$_=eval'
masak history, tab completion, interactive introspection...
cognominal it is a great way to learn
Juerd Isn't using a source file easier? 11:13
Or, rather, why isn't that easier?
masak Juerd: the feedback loop is tighter with a REPL.
cognominal indeed
masak and you don't have to type 'say' all the time :)
Juerd masak: But you end up typing the same things over and over.
masak again, history.
Juerd History is annoying for that 5 line blokc.
masak if you're used to perl -ple'$_=eval', I understand that you'd say that :)
Juerd And if you don't use multiline constructs, you don't need those variables anyway 11:14
11:14 M_o_C joined
Juerd Like I said, it's just my calculator. 11:14
masak Juerd: I don't feel the need to convince you. I *really*, really want a good REPL for Perl 6.
cognominal Juerd, so perl5 is enough except if your are an APL fan
m6locks repl could be modified so that it would accept redefinitions
Juerd You don't have to convince me, of course :)
I'm just curious
masak Juerd: I'll be satisfied with an "ah, now I get it" once we have it :P 11:15
cognominal Perl, there is more than one way to use it.
Juerd I've seen Python programmers go crazy and use their interactive mode all the time, and the only thing I thought was: why on earth would you do it like that.
masak is there a proof-of-concept of using ReadLine from within Rakudo?
does anyone have the knowhow to make one? 11:16
Juerd The things that are small enough are great for oneliners in -e, and the rest is annoying to repeat in a repl.
moritz_ -e has the disadvantage of adding your shell's quoting layer to it 11:18
which is not a problem in 95% of the time, but very annoying in the 5% where you get it wrong
cognominal I switched to Perl to avoid to mess that quoting layer 11:21

pmurias hi 11:27
masak \o 11:28
would it be a mistake to require subtype checking not only on assignment, but also on declaration? so for example 'subset Odd of Int where { $_ % 2 }; my Odd $uninit;' would error out at runtime at the latest. 11:29
colomon how would you check that? 11:30
masak just run the subtype check at some appropriate moment.
pmurias masak: that seems resonable 11:31
masak similarly for object attributes with subtyoe restrictions. the object would error out instead of being created inconsistently. 11:32
colomon I mean, how would you make a subtype check detect the example conflict? 11:33
masak colomon: I'm sorry, except for the answer I gave you, I have no idea what you mean.
pmurias masak: one problem i can see is my $foo;if foo() {$foo = ...} else {$foo = ...} like scenarios 11:36
masak how and why is that a problem?
colomon If I say 'subset Odd of Int where { $_ % 2 }; my Odd $uninit;', how does the compiler know that's wrong? If you're assigning a value, it's easy to test that the value can't meet the constraints. But how can the compiler know that *nothing* meets the constraints?
afk # diaper change
moritz_ colomon: it runs the type check
colomon: on the default value, which is an Int type object 11:37
masak colomon: supposedly, init-ing an Odd-subtyped variable would amount to assigning the Int type object to it.
11:38 M_o_C left
masak colomon: the problem is that it would probably be done in what jnthn calls the proto-lexpad, which is not necessarily at runtime IIUC. 11:38
but if all that means is earlier errors, that's fine :)
pmurias masak: sometimes i want to declare a variable in some common outer scope and then initialise it in two common places 11:39
masak pmurias: yes, sure!
pmurias: ah, now I see what you mean.
pmurias: I think that concern is smaller than not having variables in an inconsistent state.
but that's just my immediate reaction. there might be places where that becomes a real problem. 11:40
also, it might turn out that it's philosophically impossible to assume that the variable isn't always assigned a (possibly inconsistent) default value at the start of the block. 11:41
in fact, I think that's the sad truth of it. :/
pmurias is confused by that
moritz_ just find a default value yourself
masak pmurias: well, you can use the varible in the rhs of the declaration assignment, right? 11:42
pmurias: that means it has *some* value even before the first assignment.

compared to rebuilding rakudo 11:52
11:52 iblechbot left
masak tests 11:52
currently it takes 6 seconds. 11:53
oh! I just remembered Yapsi runs off alpha, so it'd be using the alpha target, if any. 11:54
moritz_ that's basically immutable anyway
masak nod.
moritz_ 6 seconds including all dependencies?
masak no dependencies at present. 11:55
perhaps in the future GGE will be one.
and with it, a Perl 6 grammar.
moritz_ how do you parse now? built-in Perl 6 grammars?
masak aye.
extremely simplified. 11:56
see the top of github.com/masak/yapsi/blob/master/lib/Yapsi.pm
in fact, I think getting support for STD.pm, GGE and Rakudo parsing should come fairly soon. it will necessitate a common way to communicate ASTs. 11:57
which will be important in itself.
moritz_ that's sweet :-)
(the current grammar, I mean)
masak it is :)
it's a sweet, complete-in-itself subset of Perl 6.
I first wrote that code, grammar and subs, in Perl 5 and Regexp::Grammars. 11:58
it was a joy to use in many ways. I realized that Perl 5 and Regexp::Grammars both rock. specifically, I feel a great confidence when using those tools that I don't get in Perl 6. 11:59
moritz_ :-)
in two years, you will 12:00
masak then, when porting it all to Perl 6, I felt clearly that Perl 6 rocks. :)
specifically, the regex syntax is so schweet, and multi subs help keep things atomic and reduce clutter in other ways too.
moritz_ aye
and then you use proto tokens...
masak one place where Regexp::Grammar really shines right now and Perl 6 regexes don't is in the output produced. 12:01
I still feel that $/ is really tough to traverse.
pmurias masak: the output of STD is more a parse tree then an ast 12:02
masak pmurias: whazzedifference?
moritz_ masak: aye. The many rakudobugs associated with $/ don't make things easier
actually .caps and .chunks are supposed to make it much easier 12:03
pmurias masak: it reflects the particular way the program is written rather more of the program meaning
masak: like PAST vs the $/ from rakudo's grammar
masak moritz_: the second param of the find-vars and sicify subs doesn't have a parallel in the Perl 5 code. it's cool to be able to use constants in that way, but in the end it's a workaround for something missing in Match objects.
moritz_: I've never really used .caps and .chunks. is there a tutorial somewhere? :) 12:04
pmurias: good point. I suppose it's the parse tree I want, actually. 12:05
not the AST.
moritz_ masak: tutorial? are you kidding? they are specced, tested and implemented (in alpha), that's not a bad start...
masak moritz_: oh, ok.
moritz_: I will have a look at the tests, then.

pugssvn r30386 | masak++ | [t/spec/S05-capture/caps.t] rw review -- fixed braino
masak moritz_: yes, I think it is. but what I'm missing specifically from Regexp::Grammars in Perl 6 grammars is that Match objects 'know their name', i.e. something which parsed as a variable is typed as AST::Variable. 12:14
see for example findvars in github.com/masak/tardis/commit/b598...6e5#diff-3 12:15
(that's the Perl 5 prototype of Yapsi)
moritz_ isn't that what .ast is for in Perl 6? 12:16
masak you mean putting something there to give a clue? I guess.
but that would have to be done manually for each particular case. in Regepx::Grammars it just happens. 12:17
'feature envy' :) 12:18
I also really dig the debugger. hope I'll get the presence of mind to finish implementing grammars in GGE soon, so that I can steal^Wport the debugger from Regexp::Grammars. 12:19

TimToady masak: re grammars "just working", I'll just point out that viv spits out VAST::variable for a variable, and that's not because there's a 'make' for it--it's done by an AUTOLOAD

TimToady and if you break apart the radicals, it's more like "sit down under a big roof", implying "sits in a respectable place like a palace" 16:58

sundar What's the best place to look at some example Perl6 code? are the Euler examples in the pugscode repo current? 21:02
21:03 hercynium left
cognominal sundar, rakudo the most advanced implementation so far, contains lots of code in Perl 6 21:04
And by nature, it is not allowed to rot.
on the other hand, that is not slef-contained code. 21:05
sundar cognominal: does it have, for eg., string manipulation, file handling, etc.?
cognominal But Perl 6 being destined to write big programs, they are good examples. 21:06
supernovus sundar: github.com/masak/ and github.com/supernovus/ have some self contained examples, but most of them only work with the January rakudo release, not the current master.
cognominal My interest being regex and grammars, the rakudo code is a feast. 21:07
sundar supernovus: thanks. have there been that many changes since Jan?
supernovus sundar: In Feb, rakudo migrated to an entirely new master branch that is a rewrite. The way it has been designed is way superior, and it offers huge benefits over the previous 'alpha' build, but not all of the functionality from 'alpha' has been reimplemented yet. 21:09
21:10 Trashlord left

colomon no, proto is more akin to CPAN for Perl 6
at least, the downloading and installing portion of CPAN. 21:18

bkeeler The changes to cperl-mode.el were never integrated, and the real cperl-mode has advanced quite a bit, to the point where the hacked version in pugs repo just doesn't work on any modern emacs 22:36

sorear because I don't actually know anything about the spectest harness
colomon You have a Rakudo build? 23:51
sorear yes
I also know about make spectest
what I don't know how to do is to run an /uncommitted/ copy of the spectest
or a single file from the spectest, rather
colomon If you have uncommitted changes when you run make spectest, it will run them. 23:52
bkeeler easiest way is (cue TimToady rant): make t/spec/S01-foo/bar.t
Which will fudge if necessary
sorear colomon: That involves an unpleasant amount of magic. How, exactly, does make spectest find out where my pugs checkout is? 23:53
colomon sorear: oh.
make the changes to the version of the spectest in your rakudo/t/spec directory.
bkeeler It checks the tree out from pugs below t/spec
colomon then check it in from there as well. 23:54
bkeeler Personally, I symlink t/spec to the appropriate place in my pugs checkout
colomon I never touch t/spec in my pugs checkout, I just work with the copy of t/spec rakudo checks out. 23:55
sorear .......... 23:56
mat t/spec/... doesn't work
it's decided to REBUILD RAKUDO
instead of just running the test
colomon yes, make test or make spectest will rebuild Rakudo if you have changes in it and haven't run make. 23:57
