yeah, what's up?
did you see your pm?
frue uh 01:56
no
sorry, frooh is the work computer 01:57
so if you pm'ed that one I won' see it
s1n doh, okay
frue actually
s1n you have too many nicks
frue lemme just ssh in
it will only take a sec
well, even if I was frue_ here it still wouldn't get to me :-) 01:58
s1n you should pick 1 active nick and make the others "*_away"
frue maybe I will...
s1n it's typical on IRC to do that when you can't see messages as that nick 01:59
frue ok, so I am reading these now
it will take a sec
s1n let me know when you're done reading

frue ok, I see how that workflow is attractive, but we really can't pull that off 02:11
that assumes Alice and Bob can merge with the central repo
s1n yes, but the central repo was not specified 02:13
this is where the workflow change comes in 02:14
frue ok...
s1n that graham and i were talking about
frue I see exactly what you mean
s1n it won't go to rakudo/rakudo, that's only the topmost blessed official version
alice/bob will send theirs to their respective .... "manager"? 02:15
frue so the idea would be that I do my stuff, like mentioned in thething
then post to my repo in a branch
and then jnthn or something pull from mine to theirs
s1n yes, there's also a subtle thing in there
frue do stuff with it
s1n yes, absolutely
frue and then merge
that makes sense
stumble thing?
s1n junio refers to them as "topic branchs"
err s/s/es/ 02:16
to they tend to keep them for small changes
frue right...
oh, subtle, not stumble. Read-o
s1n that's what i said :)
frue hence the read-o 02:17
:-)
s1n so, see what i mean by how we're doing it wrong
i think we should try this out, you and i
frue sure...
s1n gimme some time though, i'm working on tagging my notes (school work)
frue but in general the main thing that will change is that instead of mailing a patch I push to my remote repo and email you (or send a pull request)
that's fine 02:18
s1n yes
where RT is just a linkfarm to patches
frue ah...I like that
s1n rt would be used only for discussion
frue which makes sense
s1n yes, i actually like this better 02:19
frue and then instead of squashing stuff, you pull fromme (or vice versa) and to see what went down you (or I) just use git diff branch master or whatever
s1n but in reality, we need the lieutenants
frue right
s1n without them, the git model breaks down
frue but it would make more sense if we figured out the mechanics of that and showed someone else how to do it 02:20
s1n and it reverts back to svn with blessed access
frue yeah
well, slightly nicer than just svn
we can move files and delete files without hassle
s1n yeah, but you get the idea
frue yeah, agreed
s1n i'd like to try this out soon, maybe spend an hour or so, and see how it works 02:21
frue so you wanna experiment with stuff and then when we figure out what works well take the next steps?
s1n yes, absolutely
frue well, let's plan a time next week to do it
is that cool with you?
02:22 justatheory joined
s1n well, we don't have to do anything meaningful 02:22
frue yeah
s1n just set up a dummy repo and try it out, shouldn't take longer than an hour
frue but I am busy on sundays and I am sick right now
s1n i should have time for that tomorrow after the dog training class
frue so we can't do it till monday
well....
s1n ahh okay, then it'll have to be wednesday night or later 02:23
frue yeah, sunday the earliest I could would be 10ish
meppl good night
s1n that's a bit late, i get up for work at 5
frue yeah, then lets not tomorrow
s1n wed night or later is fine for me
frue k 02:24
lemme make a mark on the old calendar
let's say wed at 8?
s1n ...
02:24 meppl left
s1n that might be alright, i get out of my exam ar around 6 02:24
frue well, 8-10 is a fine range 02:25
s1n sounds good
frue we'll say 8 and if it's later that's not a huge deal
s1n lemme send you another good link
frue alrighty
s1n read that, it's very useful 02:26
frue on it

mberends socat is a brilliant improvement on netcat, it makes podserver forking concurrent in a manner of speaking. 10:24
10:25 parduncia left

Meijito How to get random text from @list = ("aaa", "bb"); ? I used $text = rand(@list);, but my answer be just: 1.13671875.

Meijito Ok.
10:31 Tene left
ihrd rakudo: <a b c>.pick.say 10:31

p6eval rakudo de786f: OUTPUTĀ«aā¤Ā»
ihrd so, should @array.push(%hash) put one item in list, or rakuso work properly when put list of pairs insted? 10:33
masak somehow it seems reasonable that it pushes a list of pairs.
it's analogous to @array.push(@other-array) which pushes the elements separately. 10:34
ihrd hm... but > my @l; @l.push({a=>1, b=>2}); say @l.perl; 10:35
[{"a" => 1, "b" => 2}]
mberends there is a reluctance to flatten lists, because that loses structure 10:36
masak well, that's different.
ihrd but, why it loose structure?
why {} and %hash in push have diffirence? 10:37
mberends it should be that if you push two hashes one after the other, they don't merge.
masak ihrd: it's just as [] and @array in push are different. 10:39
ihrd hm, I see. 10:41
but with hash it still looks strange for me :)
masak aye :)
I didn't even realize we still had \ for this :) 10:42
10:42 kate21de left

10:46 disismt joined
mberends that oops does not seem to be wrong, just beyond the expressiveness of .perl 10:47
ihrd .perl cant show deeper?
mberends it looks that way 10:48
masak that's right. 10:49
ihrd ah, this is make closure
masak the 'oops' was because I expected something else, not really because there's anything wrong with Rakudo.
ihrd: aye.

masak: tbh I've not much idea yet how to cleanly handle recursive data structures with .perl. 13:12
Part of me wonders if we should.
masak jnthn: thing is, I don't see why this should be recursive in the first place. 13:13
it's not like I'm doing binding.
just regular assignment.
13:14 Whiteknight joined
jnthn You're still creating a circular reference. 13:16
13:16 parduncia joined
jnthn So far as I can tell. 13:16
I guess context vars would make a recursive .perl easier. 13:17
erm, sorry
a recursive-data-structure-safe .perl easier.
Alas, we don't have those. Yet.
masak jnthn: if that creates a circular reference, how does one spell what I meant to write? 13:19
13:20 cognominal joined
jnthn masak: What is it you want exactly? 13:20
masak i.e. take the hash _value_ of that particular key, insert it into an array, and make the new hash value that array. without circular references.

jnthn might hack on some Perl 6 stuff a bit later 14:28
Going to do some natural language stuff first. :-)
masak jnthn: thing is (and I'm guessing here), you'd get a kind of schwa half-sound between the 'str' and the 'bske'. it sort of has to be there to make it pronouncable.
s/ca/ci/ 14:29
jnthn masak: Right. r and l can act vowel-ish in Slovak if needed. :-)

masak huh? you get that when you do 'git add src/classes/IO.pir'?
jnthn No, I did it when I did git pull 15:26
masak ah.
jnthn I have local changes to it, and someone else has also made changes.
masak yes.
that's why you cannot merge.
jnthn Suggestions? :-)
masak hm.
git stash?
maybe not.
jnthn damm, I jus typed it! :-P 15:27
masak jnthn: this will sound a little haughty, but I seldom end up in that kind of situation nowadays in my git usage. :)
so I don't know what the best measures might be.
jnthn heh 15:28
masak anyway, did the stash thing work?

at least in my workflow. 15:32
it goes like this: branch, hackhackhack, switch back to master, pull, switch back to branch, rebase, switch back to master, merge, push.
it's the rebase step that contains all the wonderfulness. 15:33

masak it makes the strife of mergine occur (1) in my local branch, away from all official things, (2) one commit at a time, and they're _my_ commits, so I can manage the conflicts better. 15:37

jnthn wow 15:58
Matt-W nice!
masak I'll nopaste it for you. :)
jnthn masak: Is November targeting Oslo now?
masak jnthn: theoretically, yes. 15:59
ihrd and I tried it on HEAD today, but we're supposed to be targetting Oslo.
so is proto, I guess.
I want to start dogfooding proto; then I can build everything off Oslo. 16:00
Matt-W I think I'll target HEAD with Form, I seem to need bugfixes a lot :) 16:01
And it's in no way a product yet
masak gist.github.com/83212
Matt-W masak: :)
masak Matt-W: that's fine. just be aware that proto targets latest-release Rakudo by default.
but I suspect that proto still has very few users, so... 16:02

16:17 sri_kraih_ joined
cspencer generally speaking, should methods in the setting be arranged in alphabetical order? 16:19
or to put it another way, if i alphabetize them, will anyone complain? :)
masak I might, for 'git blame' reasons. but not very loudly. 16:20
jnthn cspencer: Alphabetical order is good, yes.
cspencer alrighty :)
jnthn But maybe not worth the effort to go through re-ordering everything for now.
cspencer well 16:21
i was going to add more methods to a particular file and clean it up at the same time
jnthn Ah, OK.
Which one, BTW?
cspencer so it's not too much of an effort issue for me
jnthn In that case, fine.
cspencer Any-*.pm primarily
jnthn OK.

something similar is likely already in there.

masak I still think there's a vacancy for a second type of "bug wrangler" in the Perl 6 commune: one who does his damndest to keep the bug count down. :) i.e. closing bugs that are fixed but forgotten, merging bugs that are the same, rejecting bugs that are wrong... 16:42
jnthn wonders how on earth he managed to pass the whole suite apart from crashing on tspecS05-massrx.rakudo

masak: Is unpack meant to work as a method on string? 16:50
masak jnthn: not that I know.
jnthn Hmm.
Ok
masak though the specs on unpack are a bit vague.
jnthn unpack is the unlucky (completely by chance, but no fault of its implementation) function that manages to have a regex block that ends up conflicting with the name of one in the setting. 16:51
16:51 Psyche^ joined
masak jnthn: interesting. 16:51
jnthn And sicne they are methods, they end up conflicting sicne they are int he same namespace.
masak it's a method? I don't think it should be. 16:52
feel free to demote it.
jnthn All regexes are method-y.
masak oh, the regex.
jnthn masak: Yeah, but it's not a problem with unpack.
16:52 Patterner left, Psyche^ is now known as Patterner
jnthn Just an issue of things conflicting. 16:53
masak is there a way to resolve the conflict?
jnthn Turns out, putting unpack after lines in Any-str.pm rather than before makes the test pass again. ;-)
I think I'll do that and ask pmichaud for his thoughts on a real solution. 16:54
He may already have one in mind.
16:54 gdonald joined
masak ok, good. 16:54
jnthn Anyway, this means I can put in my patch to import stuff from the setting.
Which means that, say, lines written in the setting in IO (the lines variant that takes a file handle rather than a string) now works. 16:55
As lines($fh);
When put in the setting.
masak rakudo: class A is Array { method foo($x) { say $x } }; my A $a .= new; $a.push(5); $a.foo("OH HAI") 16:58
p6eval rakudo de786f: OUTPUTĀ«OH HAIā¤Ā»
masak it boggles my mind that that works.
jnthn Why? 16:59
masak I don't know, really.
jnthn A is just a class, you can inherit from it. :-)
masak it feels like a one-liner with many possible points of failure.
jnthn erm, Array, rather...

Fix a braino in my first cut of import; we may only want to load the module once, but we may need to import many times into many different scopes, so checking we only imported the first time was completely bogus.

kudo: f6e7fcb | jnthn++ | build/gen_setting_pm.pl:
Get gen_setting_pm.pl to generate use statements at the end, which import the various classes in the setting. We also have to make sure we note them in %*INC so it doesn't go trying to load Any.pm, etc from disk. This is fine for when we're compiling - just use a BEGIN - but since those aren't persisted we need to make sure we set up %*INC in the pre-compiled version too. Did it with a sick hack for now; hopefully someone thinks of a good way...
kudo: 34d36f0 | jnthn++ | src/ (3 files):
Four more methods from IO moved to the setting, including lines (which is now imported from the setting, by other recent changes, thus why it is safe to mvoe without breaking any tests).

masak mahen: even Perl 5 hasn't had a "final release".
mahen: not many programming languages do.
jnthn mahen: If what you mean is, do we have a complete implementation of the Perl 6 spec yet, the answer is no. But there's plenty that is implemetned today that you can play with. :-) 17:07
mahen so can we call it stable enough to use
Diederich Regarding a 'GA' version,
masak mahen: I use it daily. it's fairly stable by now.
Diederich it's closer now than ever
mahen r u still bootstrapping it from parrot 17:08

mahen there are 3 choices on dev.perl.org 17:09
which should i choose?
masak Rakudo. 17:10
satisfaction guaranteed, or money back.
mahen ok
jnthn realizes that if we can port almost all methods of List and Array over to the setting, it will make the refactoring that is needed later on far, far, easier. 17:15
masak dang! lines($file) isn't in Oslo! :P
I've already come to depend on it...
17:16 PZt left
jnthn Oh? 17:16
Hmm.

davidfetter hello
mberends no gain without pain, ok
Matt-W hopefully we can make that up and more with compiler performance work 17:19
davidfetter anybody packaging rakudo into RPMs?
jnthn But once we migrate stuff into the setting, they get Perl 6 signatures and auto-threading just falls out naturally too.
So it should be for postcircumfix:[ ] also.
Matt-W jnthn: does Perl 6 with inline PIR still autothread? 17:20
jnthn davidfetter: I haven't heard of anyone doing that.
davidfetter k
jnthn Matt-W: Yes and no, depends what you mean.
davidfetter would you likely have if there were somebody?
Matt-W davidfetter: if you want an easy way to try it out, look at proto
jnthn Matt-W: If you mean, you write something in the setting and it has embedded PIR in a method, then calls to that method would still auto-thread. 17:21
It's that the method has a Perl 6 signature that is key;.
davidfetter Matt-W, actually, i'm looking for a way to package it so others can try it out. i'm ok with perl Configure, but yum install will get more people on it
Matt-W jnthn: excellent
17:21 mahen left
Matt-W davidfetter: true, true. now we have parrot 1.0, there may be people looking at packaging that 17:21
jnthn davidfetter: Agree it would be a nice thing.
davidfetter has a yum-installed parrot 1.0.0 on his f10 box atm :) 17:22
Matt-W ah it's already done, great
davidfetter which is what got me on this track
well, it was yum localinstall
jnthn davidfetter: Don't think that Rakudo plays too well with installed Parrot right now, though...
davidfetter but still :)
hrm
jnthn That might get in the way of what you want to do.
davidfetter that's not so great
Matt-W yeah Rakudo's build system may need some work to support that properly
davidfetter what all's in the way at the moment?
17:23 Whiteknight left
jnthn davidfetter: I'm not sure what the issues are, pmichaud is more likely to have a better idea. 17:23

jnthn I don't know that there's that many things in the way of making Rakudo installable and using an installed Parrot, it's just not something anybody has had tuits to do yet.
davidfetter hrm. looks like he's out for the weekend
jnthn I think other languages, e.g. Lua, have looked at this a bit. 17:25
davidfetter oh? do those devs hang out in irc.perl.org/parrot? 17:26

Matt-W puts on his giant beard
santax i have a quick question
just installed parrot 1.0 and rakudo 17:32
so I wanted to try it as cgi
i have Webweaver as web server
so I made a small hello world cgi, but it gives: "This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information. src\io\api.c:451: failed assertion 'pmc'" 17:33
the script runs nice in command line though 17:34
skids IIRC the perl6 executable kinda still expects to be run from inside the source tree.
It's not a real executable yet, unless things have changed recently. 17:35
santax it's in the path
skids It may have to be the cwd
jnthn santax: Also, libparrot.dll maybe needs to also be in the path if it's not already.

17:37 jferrero left
jnthn OK. 17:38
Hmm. I don't remember seeing that assertion fail before. Odd.
Check libparrot.dll is in your path though, that may be it.

Yeah, worse, the bug evaporates under the debugger.

jnthn Matt-W: eh, curious. It's moving item from PIR to setting that triggers it. 17:57
Moving just that one back makes it go away.
Serious wtf. 17:58
Matt-W jnthn: Okay you win the weird prize
cspencer anyone know where i might find the official signature for the Any.trim() method? it doesn't appear to be in S32... 18:00
(or perhaps it's not been fully specced yet?)
18:01 msmatsko joined
jnthn cspencer: The latter is quite possible. 18:01
cspencer alright - should i just leave it as it right now or redo the PIR version it P6? 18:02

Matt-W do it, do it! 18:04
jnthn cspencer: Do it, and patch S32 also. ;-) 18:05
cspencer will do :) 18:06
Matt-W gargh
why won't this bug reproduce
oooh
ooooooh
it's different if I don't run it under prove 18:07
hmmm
jnthn Ouch. That's never a good sign.
Matt-W yeah
it still loops but it seems to do it in a different place 18:08
jnthn Matt-W: If you want to find out something very nasty
../../parrot -G perl6.pbc thingy.p6
which disables GC
If it's a garbage collection bug, this will make the problem go away.
Matt-W jnthn: no still does it 18:09
memory climbs like crazy though
jnthn Matt-W: Sure, it will because it's not re-claiming any. :-) 18:10
Matt-W: OK, that this didn't help is something to be glad for. :-)
If -G helps, we're in the crap.
Matt-W yeah but it shows that the loop is causing stuff that's being reclaimed, rather than allocating endlessly
which might be a hint as to what's going on
not a very good hint though :)

Matt-W ooh
jnthn moritz_: Aye, some bits. :-) 18:18

Matt-W jnthn: found it 18:19
rakudo: my $x = "wibble"; $x.subst(/<ws>+ $$/, "");
probably shouldn't have done that...
sorry feather... 18:20

Matt-W yes that was ridiculously dumb
can anybody get in and kill it?
18:20 p6eval left
jnthn Apparently so. 18:20
moritz_ it's doing that itself
18:20 p6eval joined
Matt-W oh cool 18:20
very cool
moritz_ it has a CPU time limit
santax jnthn: I downloaded your pugs binary and tried cgi with it - works like charm :)
Matt-W and that would've chewed CPU like crazy
jnthn santax: Oh my, those binaries are...oooold. 18:21
moritz_ so the only condition where p6eval hangs is when it reads from a (blocking) stream
Matt-W moritz_: the usual problem, hard business to solve that
cspencer i see trim.t references "trim_start" and "trim_end" methods but indicates that they're not implemented - were they destined for S32 but never happened?
Matt-W doesn't like blocking network IO
jnthn: anyway, that's where my loop seems to be ,shall I file a rakudobug?
jnthn cspencer: I seem to remember there was a p6l thread not so long back abotu trim 18:22

Matt-W I suppose
rope... hang...
jnthn or where -> $x is rw { ... }
And then the constraint can modify the variable too. 18:57

moritz_ will do
jnthn Matt-W: Ah, OK.
Matt-W jnthn: which is a bit more reassuring
jnthn isn't sure if what moritz_ just ran is sick or awesome.
Matt-W actually I should add a note to the bug 18:59
moritz_ probably both ;-)
Matt-W it seems to be to do with repetition quantifiers on <ws>
because I tried another match with <ws>+ in it and it looped too
moritz_ jnthn: just a weird idea... you could implement coercion like that
jnthn Erm
Doesn't <ws> actually match multiple whitespace anyway?
By default, that is...
Matt-W I don't know 19:00
jnthn moritz_: That'd be...weird. :-)
Matt-W but it shouldn't cause an infinite loop
jnthn Matt-W: Oh yes, it's a bug for sure.

moritz_ it sure *is* weird

jnthn yeah
Matt-W: Any reason not to use \s+ ?
moritz_ jnthn: I know, just playing around with the stuff
jnthn ws is a tad magical.
cspencer i'm attempting to move sqrt from PIR into Any.pm but i'm having some issues
there's a version for Float/Int in any-num.pir
jnthn moritz_: Aye. I'm kinda happy it works in Rakudo.
cspencer and another for Complex in classes/Complex.pir 19:02
jnthn cspencer: Ah. Are they exported/multis?
cspencer but i can't seem to get the complex one to be called
yes, exported/multi's
19:02 jyy joined
jnthn You've probably hit on a limitation in my "things to fix soon" list. :-( 19:02
cspencer ah, ok :) i'll back off of sqrt for the moment then :) 19:03
jnthn We aren't sticking the type properly on invocants in signatures.
cspencer gotcha
moritz_ rakudo: sub sqrt(Complex $x) { say "in Complex" }; sqrt(1+1i)
p6eval rakudo 1d2451: OUTPUTĀ«in Complexā¤Ā»
Matt-W jnthn: no not particularly, in fact that's what idid to dodge the loop
jnthn moritz_: That's fine. The problem is when you write it in a class and expect the invocant to automatically get the type of the class.
moritz_ rakudo: multi sub sqrt(Complex $x) { say "in Complex" }; multi sub sqrt(Any $x) { say "in Any" }; sqrt(1+1i)
p6eval rakudo 1d2451: OUTPUTĀ«Null PMC access in find_method()ā¤current instr.: '_block14' pc 105 (EVAL_16:48)ā¤Ā»
cspencer jnthn: that would explain some other issues too then 19:04
thanks ;)
moritz_ but that... shouldn'T happen, right?
jnthn moritz_: That's likely because sqrt is already defined as a non-Rakudo multi-sub.
moritz_: Combining the two causes issues - we have a ticket saying as much, though it was max in the ticket.
moritz_ ah. One more reason to move stuff to the setting
jnthn This is yet another...right.
moritz_ rakudo: multi sub s(Complex $x) { say "in Complex" }; multi sub s(Any $x) { say "in Any" }; s(1+1i) 19:05
p6eval rakudo 1d2451: OUTPUTĀ«in Complexā¤Ā»
jnthn Seriously need to fix that invocant thing though.
OTOH, on Friday night I seriously needed to fix importing of multi subs, so that was another step to getting us able to shove everything in the setting.
Matt-W whenever you fix something, there'll be something else you really need to fix right behind it 19:06
jnthn Aye. 19:07
skids Damn, and I was so looking forward to my daily bombardment-of-ruoso-with-minutia session.
19:07 NordQ joined
skids Anyone else like iterators enough to speculate on them? 19:08
Matt-W I'm always happy to baselessly speculate 19:09
skids OK. easy one first: what do you get if you @a <== 1..Inf; @a.pop; ?
Matt-W hmm 19:10
Inf, I suspect
19:12 msmatsko_ joined
Matt-W but doing it again probably wouldn't be wise 19:12
skids Then, what do you get if you @a <== map({ $_ ~ "#"}) <== 1..Inf and then pop?
19:12 msmatsko_ left
Matt-W depends what Inf stringifies to? 19:13
skids My vote is for a thrown exception, actually :-)
moritz_ it'll probably loop
because @a.pop will try to access the last item
Matt-W my original answer depends if it's smart enough to spot that Inf is the last item without iterating the entire list
it might not be 19:14
skids It may have to, because if you have a generator of unknown but finite length, you'd want it to work.
moritz_ so it'll try consume the iterator, and run out of space somewhere
Matt-W if you're dealing with finite lists, you're going to have to accept evaluation of it at some point
19:15 wknight8111 joined
skids Maybe the safest answer is that you "MAY get an exception if the implementation can detect an infinite loop beforehand, but in any case MAY get and infinite loop" (where MAY is spectalk) 19:15
Matt-W playing around with the far end of an infinite list is potentially dangerous 19:16
Haskell can't spot them
skids Now the trickier one.
jnthn skids: I think that sounds reasonable.
moritz_ indeed
skids If you index a finite but unknown iterator until it runs out of elements: 19:17
@a <== some_generator(); while (@a[$i]:exists) $i++; 19:18
lambdabot Maybe you meant: activity activity-full admin all-dicts arr ask . ? @ v
skids Then @a has cached values.
But is it shaped?
moritz_ if you don't know the size beforehands, and @a isn't declared to be shaped, it's not shaped 19:19
19:19 davidfetter left
skids So then you can @a.push at that point and it is a normal array? 19:19
moritz_ when you push to @a, it'll block at the point until the generator is exhausted 19:20
at least that's my understanding
19:20 ZuLuuuuuu joined
skids So once the generator is exhausted, it becomes a normal array? 19:21
moritz_ yes
19:23 msmatsko left
skids is out of minutia for the time being. 19:23

moritz_ dukeleto: maybe... 20:28
dukeleto moritz: i did add the NaN checking to sign
moritz_ dukeleto: one more thing... you're implementing the fundamental functionailty in the sub, and in the method you retrieve the sub and call that... usually we do it the other way round 20:29
so that people get all the merits of polymorphic method calls when the use the sub as well
would you mind doing it "our" way? 20:30
dukeleto moritz: sounds good, that was just the first way I got stuff to work, there is much refactoring to be done
moritz: of course
so I should make the stuff in math.pir call the functions in any-num.pir ?
moritz_ dukeleto: I think you should implement the method that does all the work in src/classes/Complex.pir 20:31
and then add subs in math.pir which call that method 20:32
jnthn moritz_: For .sub 'roots' :multi('Complex', 'Integer')
That makes sense.
Does .sub 'roots' :multi(_, 'Integer') 20:33
not belong in Any-num?
moritz_ yes, jnthn++
wow, the "network" tab on github is quite impressive, with 31 entries 20:36
dukeleto i must admit, I did not fully understand multi method dispatch when I starting roots(), and I feel that I only marginally grasp it's full power now. I am sure there is much room for improvement 20:37

moritz_ in control.pir the thing that's passed to .'compile'() is actually a pmc, not a (native) string 22:13

moritz_ $P0 = $S0
jnthn moritz_: I think it just gets strigified anyway. 22:16

jnthn say $S0

Suppose you want to call something in a namespce, like Foo::Bar::Baz 22:35
You'd do
$P0 = get_hll_global ['Foo';'Bar'], 'Baz' 22:36
szabgab are print and say in PIR ?
oh and I want to .return() the value(s) 22:37

szabgab I get back Parrot::PMC=SCALAR(0x86fe4a0)
jnthn Right. 22:40
So I guess you can stringify it afterwards?
cspencer hmmm....when i do a "make spectest" i'm getting a lot of "Unknown introspection value 'symbols'" - is that something i've done to break my local tree?
jnthn cspencer: That or excessively old Parrot. 22:41
moritz_ cspencer: it's nothing I get here
jnthn symbols is for lexpad introspection
cspencer hmmmm
jnthn er, lexinfo
And was added not that long ago.
cspencer should that happen with the --get-parrot option to configure or should i pull the latest and greatest parrot version? 22:42
s/get-parrot/gen-parrot/
jnthn For anyone interested I've uploaded my slides now from Belgian and Ukrainian workshops. www.jnthn.net/articles.shtml 22:43
cspencer ah ok, i was way out of date
jnthn --gen-parrot should do it...
cspencer i'm working on a different machine than i'm normally on and had forgot to use --gen-parrot that recently
szabgab jnthn, that was my typo, now fixed it and Iget : 22:46
Enter your name: Segmentation fault
much beter :-)
better
22:47 icwiener left
jnthn ...wow. 22:47
I'm going to struggle to help you much with that one, I fear...
szabgab don't worry
jnthn (Since it's hard to debug those without local reproduction...) 22:48
szabgab I am ok with what I have now as the perl5 code does not support parameter passing anyway
I'll submit a bug report later with the code example
jnthn OK, great. 22:49
szabgab for now I might need some data stringification that works both in perl5 and perl 6 22:50
is there something already ?
jnthn Not quite sure I understand what you're looking for? 22:51
szabgab yaml, json or storable in perl 6 22:53
I think
moritz_ CSV ;-)
szabgab LSD
moritz_ szabgab: ok, you finally convinced me that we need a YAML or JSON parser in Perl 6 ;-) 22:54
jnthn .perl may help
It's like data-dumper.
moritz_ but it's not cross perl5/6
szabgab I'll start with something simple for now (such as passing a single string :-) 22:55

Limbic_Region szabgab - it really isn't much to marvel at - I mean, it happens every day you know 22:59
:P
szabgab and I see it happening every day :-(
so good night & 23:00
Limbic_Region well - when you do sleep, I hope you rest well
moritz_ good night

skids What happens when you feed from an iterator? 23:09
my $it <== @a; my $it2 <== $it; my $it3 <== $it; =$it2; =$it3;
Conjecture: dwimmery here would be dangerous. 23:11
diakopter danger is dwim's pseudonym
skids :-) unless someone can come up with an earth shaking stroke of genius. 23:12

skids basically, is @@a[N] still a capture, both in the generic case of a normal array assigned captures, and the special generic slice iterator construct. 23:24
moritz_ szabgab: I can't answer your question, but istr that TimToady agreed to removing the alias between @it and @@it, so these are two totally different variables now... I just fear this hasn't been updated in the specs yet 23:25
skids Useful to know, thanks. 23:26
moritz_ erm, sorry szabgab for accidentially hilighting ;-)
23:27 DemoFreak left 23:28 kate21de joined
skids The answer to both would probably have to be the same if @@it truly were to collapse to a normal slice array when the feed source exhausted. 23:28
23:29 kidd left
skids hrm... how to do something like @a.push(<== 1..1000); 23:31
moritz_ I don't think that's valid syntax ;-) 23:32
skids @a[*..Inf] <== 1..1000?
lambdabot Unknown command, try @list
moritz_ did you mean @a <<== 1..1000? 23:33
skids You are very clever :-) but that doesn't cover feeding to the end of @@a 23:35
moritz_ why not?
<<== does the same as lazy push 23:36
skids Oh wait, you are right.
For some reason I thought <<== had something to do with @@.
moritz_ anyway, it's a long time since I read about feeds, so MMMV
skids No you're dead on. Good. One less open issue. 23:38
Though the spec does stop short of actually saying a normal @a can be on the pointy end of that, and thus get promoted. 23:40
moritz_ well, the spec was written when @ and @@a were really the same variable 23:41
(or the other way round ;-)
skids I think <<== and slices are ortho ... I can;t find where I might have got that idea from. 23:42
moritz_ is too long in the business to believe in orthogonality ;-/ 23:43
23:43 hercynium left
skids You mean there's a reason why 2 ** 0.5 is irrational?!? 23:44
diakopter moritz_: too long on any axis and you can't see the origin :P
