japhb_ I'm getting a segfault trying to build Rakudo: 00:31
/home/geoff/git/rakudo/parrot/parrot -o perl6_s1.pbc perl6.pir
make: *** [perl6_s1.pbc] Segmentation fault
I'm up to date ... is this known?
i486-linux-gnu, FWIW 00:32
frooh lemme try rebuilding and seeing what's up 00:33
did you do a make realclean first?
I always do before a major(ish) rebuild
frooh rebuilds parrot and rakudo 00:34
japhb_ I nuked and recreated the parrot submodule ... I believe I realcleaned rakudo, as well, but let me just do it again just in case
00:35 ced-2_ left
japhb_ hmmm, it's getting farther this time -- perhaps I just needed to nuke and rebuild parrot *before* doing a realclean and configuring rakudo without --gen-parrot 00:36
jnthn japhb_: Platform? And is this latest Parrot?
00:36 alester is now known as AndyAway
jnthn japhb_: Generally, the Parrot version in build/PARROT_REVISION is the one we *know* it works under though I often develop against latest too. 00:36
japhb_ jnthn: nevermind. I fixed it ... looks like I just didn't clean up exactly right the first try 00:37
jnthn Aha, OK, good. :-)
frooh japhb_: I actually wrote a script that would update parrot and rakudo from source and then build them, if you're interested I could send it to you
japhb_ frooh: Back in the day that Rakudo was in the Parrot repo, I did as well ... but I have a feeling it probably doesn't work any more. 00:39
It was .../tools/rebaase-rakudo.pl
frooh well, the benefit here is that I don't have to entirely re checkout parrot
I have it in a separate folder and this will make a symlink to it
00:39 explorer__ joined
frooh but yeah, if you got it all working that's fine 00:40
japhb_ Like I said, it *used* to work. Glancing at it now, I'm positive that it no longer works, because it uses 'git svn'. :-) 00:41
00:41 eternaleye joined
japhb_ frooh: But in any case, I was going to recommend that you put your script in rakudo/tools/ ... or even better, merge the smart stuff in your script with whatever you can salvage from mine. 00:42
frooh I don't have commit access to rakudo
or do you mean in parrot?
japhb_ frooh: It's on github ... just fork it. :-) 00:43
frooh that's true
pmichaud: speaking of, did you look at that patch I sent to RT?
00:44 explorer__ left
frooh japhb_: your script is much more involved than mine :-) 00:44
japhb_ frooh: I was hoping to make it semi-official ... unfortunately, I think A) my timing was bad, and B) the hardcore Rakudo people already had whipped mini-scripts of their own and saw no reason to switch. 00:46
frooh right

BTW, who owns evalbot?
00:57 ZuLuuuuuu left
jnthn japhb_: I think the source is in the pugs repo, I can't remember who looks after it, it may be moritz_ (or moritz_ would probably know who). 01:10
japhb_: That looks like a Rakudo bug, BTW.

frooh ah, ok
well, good luck on that
jnthn Assigning match objects makes Rakudo explode. :-|
s1n slumps into his chair to finish creating a text author/speaker detection program 01:15
thank god for perl5
frooh indeed :-) 01:16
s1n TimToady++ for 1..* 01:17
frooh considers having evalbot do that for real...
s1n it should 01:18
make the karma ~~ Inf
frooh I think it is Inf on irc.perl.org

p6eval rakudo 84920e: OUTPUT«{"foo" => ["bar"]}␤»
japhb_ Is there any way to golf that under current Rakudo? 01:26
I'd love to just get rid of the whole second statement (containing 'unless') ... but barring that, using ||= would be nice, but that appears not to work. 01:27
frooh I thouht //= worked...
s1n yeah i was going to recommend //=
japhb_ Ooh, let me try that
Ah-ha! 01:28
OK, that's at least a step forward. Though it's weird that //= works but ||= does not.
frooh agreed
rakudo: my $frew; $frew ||= 5; say $frew;

frooh weird
I wonder if maybe it's a parsing error
s1n rakudo: my $frew //= 5; say $frew 01:30
p6eval rakudo 84920e: OUTPUT«5␤»
jnthn frooh: Yes
frooh yes it's a parsing issue?
jnthn frooh: It's parsing it as infix:<||> prefix:<=>
frooh ah, ki
k*
jnthn (Because we didn't define a ||=
)
frooh and // isn't an infix?
japhb_ jnthn: ah, and foo= does not autogenerate yet? 01:31
jnthn IIRC we can't just define it like a normal meta-op because it needs to short-circuit.
japhb_: Well, the thing is we need to handle the short-circuit at the compiler level. I think.
Actually I fear //= is not short-circuiting in Rakudo as it should.
rakudo: my $x = 42; $x //= say "hi";
p6eval rakudo 84920e: OUTPUT«hi␤»
jnthn Aye. 01:32
fail
frooh hmm
japhb_ rakudo: my %params; %params<foo> //= ["foo"]; %params<foo> //= ["bar"]; say %params.perl
jnthn Though //= is fairly useful.
p6eval rakudo 84920e: OUTPUT«{"foo" => ["foo"]}␤»
japhb_ at least that works
jnthn As is.
Yeah
I figured a mostly-works was worth it.
frooh rakudo: my $x = 42; $x //= "hi"; say $x; 01:33
p6eval rakudo 84920e: OUTPUT«42␤»
jnthn (OK, actually I wasn't thinking clearly at all when I put it in, truth be told...)
frooh it looks to me like it works fine...
jnthn frooh: It works apart from it evalutes the RHS when it needn't.
japhb_ frooh: appears to be something wrong with mixing //= and the return from say
jnthn frooh: It should not evaluate the RHS if the LHS is defined.
frooh oooooh
right
got it
jnthn So right results if your RHS is pure. ;-) 01:34
frooh rakudo: my $x = 42; $x // $x = say "hi";
p6eval rakudo 84920e: OUTPUT«hi␤»
japhb_ jnthn: why would 'say' return its printed value? Shouldn't it return Bool?
s1n rakudo: say undef // 4
p6eval rakudo 84920e: OUTPUT«4␤»
s1n rakudo: 1 // 2 01:35
jnthn japhb_: say say "hi";
erm
rakudo: say say "hi"
frooh I think s1n killed it
s1n ooo
frooh tries locally
jnthn tried using japhb_ as an evalbot ;-)
frooh it works here just fine

frooh anyone in here know of any examples of putting PIR in perl6 inline? 02:19
skids Yeah I did it with rand but haven't cleaned the patches up yet. 02:20
frooh could you nopaste the code so I can see the syntax etc? 02:21
02:21 Grrrr left
skids waiting for github to stop being slow 02:22
frooh if your code is on github a link to that would be fine too
but you might wanna tinyurl the link :-)

frooh thanks skids 02:25
02:29 alester joined 02:31 ced-2 left
frooh thought that he wouldn't need to learn PIR for the setting 02:33
02:33 ced-2 joined
skids only little bits. 02:33
Most of which can be copied from what's there :-)
frooh that's true... 02:34
any idea how I can pass a value to a parrot method?
I tried q:PIR{...}($foo)
but that doesn't seem to work
skids I remember self was just self inside q:PIR{...} lemme look a bit. 02:35
02:36 firelord joined
firelord hey everyone 02:37
frooh hi
firelord man... been a long time since I was here last.
The current built of perl6, can it perform a 'system call' to external programs ? 02:40
frooh firelord: yeah, but you can't easily get the output
I wrote something to fake it, but it's slow
fake getting the output that is 02:41
firelord well I do not need the output really, just need it to call an external app
frooh yeah, that's easy
skids frooh: I think it's ".param num n" at the top, then "func n"
firelord the external app will produce some lovely files
skids see round, etc in builtins/math.pir 02:42
firelord skids: excellent, thank you
frooh tries
firelord you too frooh 02:43
frooh no prob
firelord: you might want to try 'run("command")'
firelord frooh: thanks frooh! that should do it 02:44
frooh yep, enjoy
skids Oh I guess you may not need the .param -- that's if you are creating a PIR sub 02:45
frooh yeah
skids As to whether to use $var or var I don't know.
frooh but even doing q:PIR{ ... }($foo) doesn't work
so I'll try it?
skids The foo will have to go inside {}
02:46 ced-2_ left
frooh hmmm 02:46
no dice.. 02:47
it doesn't like me doing q:PIR{ ..., foo $bar } 02:48
it doesn't like me doing q:PIR{ ..., '$!foo' $bar }
rather
02:50 simcop2387 left
firelord thanks guys! Finally I can start writing some test bioinformatics software with perl6 02:51
frooh firelord: have fun :-)
skids oh method not sub... something like subset.'add_role'($foo) ?
frooh well, it's a sub and I am making it a method 02:52
firelord Have a good night everyone or morning if you are in Europe.
02:53 firelord left
skids wait, are you trying to put a function call at the end of a PIR arglist for some other function call? 02:59
frooh uhhhh 03:00
I don't follow
I am trying to call a PIR function from perl6

oh well
I need to get my head around gather/take
masak who doesn't?

masak mm, future laziness... 08:17
Matt-W I believe if I say
08:17 Gothmog_ left
Matt-W my @a = gather <something loopy> { <do stuff> take $something; } I end up with a (potentially) lazy list in @a which is made of the $somethings 08:18

Matt-W the line wrapping function will return a gathered list of lines - if you don't end up using them all, so what, they're lazily generated :D
(once we have laziness, anyway)
szabgab is that on purpose? 08:20
Matt-W Althoguh generally I think you'll either use one of them or all of them
moritz_ actually many built-ins work that way
szabgab that ?? is stronger than any()
moritz_ szabgab: yes 08:21
szabgab: according to S03, at least
so that you can use the ternary operator to pass arguments to functions
szabgab so I keep my ()s

one more reason to rewrite them in Perl 6

szabgab so the above is a bug in rakudo, right ?
it should give any(1, 3)
moritz_ right.
szabgab so you mean the substr() function should be implemented in Perl 6 ? 08:36

it should use the PIR substr function under the hood, though

Maddingue use Inline::Parrot; 08:39
szabgab Hi Maddingue 08:41
last time I checked i could not yet do this - only run PIR -
that's why I stopped my grant for the Parrot+Padre integration
Maddingue hello szabgab
of course, I was only joking, I have no idea of the state of Inline::Parrot :) 08:42
Matt-W It's a shame Ponie died 08:43
moritz_ I guess know that parrot is more capable and more stable it might be worth to try again
OTOH Perl 5 is so unaccessible...
Matt-W It would still be incredibly difficult I think 08:44
08:44 broquaint joined
moritz_ with tie(), magic and stuff 08:44
Matt-W don't forget no spec
moritz_ at least it has a very good test suite
Maddingue AIUI, it was because Perl5 internals, even with Nicholas and others hackers cleanings, just could not fit on top of Parrot
moritz_ much better than anthing Perl 6 has right now :/ 08:45
*anything
Matt-W well they've had more time to write one 08:46
Maddingue: I understand it was extremely difficult
And reimplementing from scratch was not considered a particularly good idea
Maddingue I haven't followed P5P recently, but remember recently reading Nicholas listing what was missing to serialize Perl5 code, and there was still major things left to do

szabgab and should not be that difficult , to someone who understands XS and Parrot 08:48
moritz_ it seems that those who understand parrot and have time are absorbed by the release process 08:49

masak mberends: been thinking more about PERL6LIB in proto. that one feels like the most blatant absence right now in the list of services to provide. it is set internally in proto, but should be set outside as well. 10:10
it's a challenge to do that non-intrusively. 10:11
I'm thinking a friendly message at the end of a proto installation, saying "You now need to update your PERL6LIB. Run './update-perl6lib' to do that automatically. 10:12
"
moritz_ isn't that '. ./update-perl6lib' or 'source ...'? 10:13
masak well,
right now I'm thinking maybe we should avoid that. 10:14
Matt-W source would only work if it was written for the shell the person was using at the time
masak what the script will mainly do is update the user's ~/.bash_profile or equiv.
and then the user can simply source that instead.
that feels less intrusive and safer for all involved.
moritz_ less intrusive? I disagree 10:15
japhb: if you have any more questions about evalbot, feel free to ask 10:16
masak moritz_: good. I like to hear points of view on this.
moritz_ masak: changing a user config which has rather global effects for that user isn't unintrusive
masak moritz_: you have a point. 10:17
moritz_ that said .bash_profile is only sourced by login shells
masak perhaps offer the commands that will make the right change instead?
moritz_ so it's not necessarily a good place
masak: that's better
10:17 alc left
masak switches to wanting that 10:17
moritz_ echo 'export PERL6LIB="$path"' >> ~/.bash_profile 10:18
or .bashrc, whatever is appropriate
masak moritz_: no, need to do a replace somehow.
perhaps sed would be the right tool here.
mberends: I think the proto projects directory and PERL6LIB are the two sources of information about installed modules. if they disagree, proto can warn about out-of-synchitude. 10:19

11:33 pmurias joined
pmurias ruoso: hi 11:34
ruoso hi pmurias 11:35
about the empty capture
I think I got confused... the empty capture is actually the "interpreter capture" 11:36
pmurias, btw... I think it's time for we to add support for weak references 11:37
since it requires an additional RI member
and an additional macro as well
masak
.oO( I've been planning my conspiracy for months now... to overthrow Rakudo development with a deluge of rakudobug tickets... )
did I just think that out loud? 11:38
pmurias what's the next thing to port over after idconst and bool?
jnthn masak: :-P
masak: I'm mostly ignoring your conspiracy for the moemnt and distracting myself with trying to implement state variables... 11:39
masak my henchmen are standing by with the rakudobug guns at the ready. be afraid, be very afraid.
japhb moritz_: I wanted to know the syntax for getting evalbot to work via /msg ... /msg evalbot rakudo: stuff wasn't working for me 11:40
masak no, actually, bug ticket reporting is a bit lower than average right now. but still nonzero.
ruoso pmurias, I was thinking that the WEAKREF member should return an object that masks the actual object but starts masking false after that value is lost... then we keep in each object a list of the weakrefs pointing to it, so we go there and override it before calling DESTROYALL.... 11:41
pmurias, that way, it fits into the REFERENCE/RELEASE policy in a way that you simply use WEAKREF where you would use REFERENCE.... 11:42
pmurias we could have a WEAKENED member that would be called on the reference when the object it's pointing to gets collected 11:44
as being overriden with a native false might be something not all weak references want 11:45
ruoso right... although WEAKENED doesn't quite mean that
maybe LOSTREF
pmurias better
ruoso but that doesn't need to be in the standard responder interface, do it? 11:46
pmurias it can be a method
ruoso yeah... an special .^! method
but... 11:47
that can be done later,
pmurias and what happens if the weak reference itself is collected before
?
ruoso it de-register itself from the referred object...
pmurias, for starts, the weakref object is private to the smop-gc code... noone else will be aware of it... 11:48
so it can do some stuff without calling methosd 11:49
a more sofisticated implementation of weak references can be done latr
pmurias so smop-gc is the next thing i should be porting over? 11:50
ruoso once we have all the s0native types, I think so
ruoso changing smop-base to support SMOP_WEAKREF 11:51
11:52 skids left
pmurias ruoso: what do we need the stage 0 interpreter for? 11:52
ruoso to be able to call "new" on mold 11:53
wait...
ruoso missing caffeine
pugs_svn r25861 | pmurias++ | [re-smop] removed the empty capture from the list of things needed in s0native
ruoso pmurias, yes... that's it... 11:56
pmurias, if you look at the current interpreter code, you'll see that there's a "prototype interpreter" 11:57
which is mixed in the interpreter code
it implements "goto" by recursing in the C stack
this is how the actual interpreter can be destroyed
I wanted to make that more explicit
specially since this implementation doesn't require gc 11:58
pugs_svn r25862 | ruoso++ | [re-smop] adds support for SMOP_WEAKREF 11:59
pmurias i'm wondering if the gc shouldn't be called refcnt or lowlevel 12:03
pugs_svn r25863 | ruoso++ | [re-smop] implement noop weakref in s0native
ruoso pmurias, I was wondering the same thing... I simply couldn't find a reasonable name
maybe refcnt-gc 12:04
or gc-refcnt 12:05
or defaultgc
pmurias refcnt-gc seems best 12:06
or gc-refcnt, as opposed to gc-tracing 12:07
moritz_ japhb: with s/evalbot/p6eval/ it works
ruoso pmurias, the problem is that we don't really support gc-tracing 12:08
so that's a bit misleadin
pmurias it should be possible to implement a tracing gc in the future 12:09
ruoso trace gc requires all objects to do the tracing 12:10
otherwise some objects will not be seen as referenced 12:11
pmurias you can keep the alive bit for the objects that don't support it in a hash
ruoso hm?
pmurias it's possible to mark an non-trace-gc'ed object by storing the alive bit in an outside data structure (like a hash table) 12:14
ruoso that's not the problem 12:15
the problem is tracedobj ---references--> non-tracedobj ---references--> anothertracedobj
pmurias the traced object will need to have a refcnt too 12:17
* objects
ruoso so what's the point? 12:18
12:21 ujwalic joined
pmurias ruoso: you're right that doesn't seem very sensible 12:23
ruoso: the prototyped interpreter seems to only have it's new and DESTROYALL methods invoked in pre-refactored smop 12:25
12:28 ruoso left 12:32 DemoFreak joined 12:36 maerzhase joined 12:58 Whiteknight joined 13:00 ruoso joined 13:03 skids joined
ruoso pmurias, I might be wrong, but I think "goto" is also implemented by the prototype interpreter 13:04
and it causes the continuation to be invoked recursing in the C stack
but yes, I think that only happens at the moment you are creating and destroying the first interpreter 13:07
masak starting from a UTF-8 string, how do I deliberately re-encode it as a string of 7-bit characters? (for use in URI escaping, for example) 13:08
moritz_ masak: for URI escape you take the bytes and encode them as %FF and the line 13:09
masak: other encodings are base64 or utf7 13:10
masak moritz_: it's the 'take the bytes' step I'm asking about.
moritz_ masak: you mean... in Rakudo?
masak moritz_: both in Rakudo and in Perl 6.
I'm looking for both answers. (as I usually am.) 13:11
moritz_ I'd guess you pack it into a Buf
masak thought so
moritz_ or maybe we need more builtins for that
something like Str.encode($encoding, :$normalizatioon)
masak can this type of thing be done with pack/unpack? 13:12
moritz_ in Perl 5 it can, I think
masak good.
then I'll find out how, and then implement that in Rakudo.
moritz_ U A Unicode character number. Encodes to a character in character m 13:13
ode and UTF-8 (or UTF-EBCDIC in EBCDIC platforms) in byte mode.
from perldoc -f pack
masak great. 13:14
should be doable in Parrot, I think.
chr/ord works that way, if nothing else.
moritz_ no.
chr/ord don't deal with bytes
they deal with characters
rakudo: say 1; 13:15
p6eval rakudo 84920e: OUTPUT«1␤»

Matt-W Woohoo!
I got my modules bug down to a test case
masak Matt-W++
Matt-W I'll file a rakudobug when my laptop has internet again this evening 13:17
moritz_ masak: that has to be accessible from within Perl 6 somehow
masak aye.
moritz_ that's what all IO does
masak I want all this, but my head is too small for encodings today. 13:18
I'm at a loss to formulate my requirements.
moritz_ you need to decompose a character into bytes using UTF-8 13:20
and then you want to percent-escape bytes that aren't valid in URIs
s/decompose/encode/
masak moritz_: I've got the percent-escape part covered. stole it from Rack.
moritz_ .trans is good for that, I guess :-) 13:21

Matt-W cool!
jnthn Matt-W: See various tests in S12-role. :-)

Matt-W why have lazy lists if you don't have lazy map/grep?
masak yes, now that I think about it...
Matt-W then you can implement my functional programming lecturer's way of solving Countdown number rounds in Perl 6 15:00

Matt-W this is true
moritz_ Matt-W: be careful, Perl 6 doesn't assert lazyness other than on infinite lists
Matt-W two jnthns would be great too
moritz_: how fortunate... 15:03
pmichaud good morning/localtime, everyone.
Matt-W moritz_: oh no, they don't end up infinite. hmm. There is a better way to do it in Perl 6 anyway, since it has side effects

pmichaud well, I saw the commit, but not the diff yet.
jnthn Ah.
Damm, I thoguth the ":-)" was indicative of a positive code-review.
;-) 15:05
Matt-W masak: you really need laziness for that...
jnthn pmichaud: I'm not handling binding properly yet.
pmichaud I'll probably review it a bit later. For now I'm very glad that it works.
Matt-W masak: well, if you want it to run reasonably fast anyway
jnthn pmichaud: If you have a moment, I'd like to pick your brain on a bug I'm trying to work out a solution for.
pmichaud sure, I have a moment -- at least until @family wakes up.
masak Matt-W: yes, it definitely needs laziness. doesn't stop someone from writing an ideal Perl 6 version, though.
Matt-W masak: no absolutely not 15:06
jnthn pmichaud: OK, I haven't *quite* got it down to its essence yet but
my $compress = sub ($x) {
state $previous;
return $x ne $previous ?? ($previous = $x) !! ();
}
my @compressed = map $compress, <a a a a b c c a a d e e e e>;
map is not using gather/take
*now
It's implemented in the setting etc
@compressed.perl ends up holding
lambdabot Unknown command, try @list 15:07
jnthn ["e", "e", "e", "e", "e", "e"]
If you do a "say" in take, it gives the expected output for each time...
pmichaud there was a long discussion related to this last week or so
the discussion centered around how we handle "return" values
but it applies to "take" also. 15:08
jnthn Ah, OK.
So I haven't got a state-specific issue? That is good to know at least...
pmichaud the problem is that take is returning the same PMC each time.
jnthn Right.
diakopter cingular gprs from amtrak somewhere in southeastern colorado
pmichaud but if we simply make "take" clone the value, then it can't really be used for creating Lists 15:09
jnthn Was there a decided solution, or is it still on the things-to-think-about list?
Yeah, I pondered clone then thought...no.
Then I tried !DEREF which of course is epic fail...
pmichaud I had to leave before I saw a decided solution, and I haven't gone back to read the logs
jnthn (Since if you're returning array refs it messes things up...)
15:10 Tene_ joined
jnthn tries to search the irclogs 15:11
pmichaud anyway, the problem isn't specific to 'state' variables. There's also an rt about it already (looking)
jnthn 20:18 pmichaud did we ever get resolution on captures, return, and the like? I didn't see it in the scrollback. 15:13
20:18 ruoso pmichaud, I saw the scrollback... but we got no resolution
pmichaud well.... there ya go :-)
RT #62178 is also related.
jnthn OK
I think in that case I'll not try and put in a fix for this...seems it needs some more serious thinking and so forth. 15:14
pmichaud agreed, and I suspect the ultimate fix will be a little hairy.
jnthn Aye.
This is one of the cases where not to scatter workarounds in the codebase for the time being IMO. 15:15
pmichaud agreed.
jnthn OK, well, at least we have state support to some degree now.
15:15 nihiliad joined
jnthn Got 4 tests in state.t that I think we could pass but currently are not. 15:15
pmichaud in rakudo's case it may come down to the pmc vs. immutable problem again -- Parrot's model of "container" doesn't match Perl 6's model 15:16

15:21 Tene left
jnthn Gah. my $bug is nasty 15:21
ruoso jnthn, we actually did 15:22
a bit after that
capture in item context returns itself unless there is one and only one argument (positional or named) 15:23
in which case it returns that argument
15:23 [particle]1 joined
pmichaud ruoso: I don't think that addresses this problem directly, though. 15:24
ruoso I can't see where it doesn't...
(the biggest confusion was because of the invocant, which no longer exists in the capture)
invocant is now only a compile-time concept
pmichaud our issue isn't to do with the invocant. 15:25
ruoso what is your issue then?
pmichaud 'take' executed repeatedly on the same scalar causes that scalar to appear multiple times in the output, even if the scalar changes value between separate invocations of take 15:26
ruoso ah... that's the other issue indeed...
which is, a value always "is ref" in a capture 15:27
pmichaud right.
15:27 Psyche^ joined
pmichaud afk for a while # vacation 15:29
ruoso my last thought on it was that the capture could provide an auto-generated signature depending on how it was built and the traits of &?ROUTINE
so methods like "take" and "return" can apply that capture against the signature to enforce the appropriate context 15:30
japhb moritz_: thank you! 15:33
15:36 sri_kraih_ joined 15:37 smtms left 15:40 ced-2_ left
ruoso pmichaud, jnthn, maybe the compiler could autogenerate a lexically scoped candidate for return depending on how it was invoked in that block enforcing the traits of the &?ROUTINE... 15:41
15:42 ced-2_ joined
jnthn ruoso: That feels hacky... 15:42
(and feels like we're missing some deeper issue...) 15:43
ruoso the thing is that the capture object doesn't hold all the information to apply that contstraints
for instance...
jnthn Since this equally applies to take also and maybe more things.
15:43 Patterner left, Psyche^ is now known as Patterner
ruoso it can't make a copy without knowing the context 15:43
the sigil provides context, otoh
so the answer is in the code 15:44
return $a, @b, %c
would mean making a scalar assignment, a list assignment and a hash assignment
hmm...
jnthn I suspect in that case it's about how we constrct the capture.
ruoso yes... my guess is that the answer is in the sigil 15:45
jnthn that is, does it actually reference $a or ($anon = $a)
ruoso the capture currently actually references $a
otherwise sub foo ($a is ref) wouldn't be able to work
jnthn Or is rw... 15:46
ruoso yes
it's just that "is ref" is the strongest, so every capture need to be constructed that way
mberends </lurk> masak: yes, PERL6LIB and a bin directory in PATH are external dependencies for proto or any installer. How to do it (.profile, .bashrc, Windows Environment) is inherently non portable. To handle it in proto is treading the slippery slope of OS detection :( ISTR you once wrote (and I think so too) that you can exit installer with a message suggesting how the user should update her environment. In per6-examples I have temporarily settled for cd < 15:48
project_dir> and make <action>, where <action> can grok PERL6LIB etc relative to `pwd`.
ruoso jnthn, but I still feel that we're going to end defining return, take and the like as keywords that apply that constraints... that seems to be the most sane way of doing it atm 15:49
[particle]1 mberends: i've been thinking about providing a command-line shortcut for setting an environment var... that would be portable, then. 15:50
ruoso jnthn, because the answer is in the AST
[particle]1 at least, the method of setting the vars would be portable
masak mberends: message on exit is probably the best course of action, yes. that was the solution moritz_++ and I arrived at today. 15:51
mberends masak: the shortcut is shell dependent, like source <script>
masak we won't do that.

jnthn You expect however 0 1 1.
masak yes.
jnthn I expect 0 1 0.
masak ok.
moritz_ expects 0 0 1 16:29
masak let's talk about the final digit then.
oh, I'm with moritz_.
my expectation had a typo in it. :)
moritz_ I'd expect the state var to be per closure
so that $a(), $a() would return 0, 1
masak exactly.
pmurias ruoso: what is the method that we invoke with the "interpreter capture"
masak that must have been the point of the ticket.
moritz_ and $b() should be totally independent
jnthn moritz_: $b *is* totally independent. 16:30
It has its own state var.
moritz_ ah, but $i is different
ouch
jnthn Yes, you change $i
Well no, $i is the same $i for all of 'em.
moritz_ right 16:31
but the initialization part is only executed the first time the closure is called
jnthn So when you do $a() the first time, it sets state $x to $i which is 0.
moritz_ right.
jnthn And post-increments $i
So when you then do $a() again later, it still has the value of 0.
moritz_ then when you call b, b's state var is set to 1
jnthn Right.
masak jnthn: I'm with you again.
moritz_ ok
masak I didn't look closely enough at the code. 16:32

jnthn moritz_: I know it just feels...odd
Also that'd stop you declaring a role Num... 19:40
Plus constant is in S04.
moritz_ ok

alester Am I missing a way to get log_filename to pipe to a process (cronolog in this case)? 20:08
sorry, ww
skids So adding junction types should be pretty cheap, right? Just the handling code for the boolean case? 20:10
moritz_ in theory, yes 20:11
in practice not every junction is implemented as a separate type
skids I was think "less" "half" and "more" would make good junctions.
20:14 PerlJam left, PerlJam joined
moritz_ the idea is nice, but so far I haven't felt the need for them 20:14
skids I only mentioned it cause it looked like it wouldn't take much. 20:15
moritz_ I fear it takes a little more than it should :/

my first setting function :) 20:27
moritz_ masak++ 20:28
masak entirely motivated by laziness, I might add. 20:29
I didn't want to implement my additions in PIR.

dalek kudo: 72f522d | (Carl Masak)++ | src/ (2 files):
translated &unpack from PIR to Setting
 20:34
masak moritz_: interesting fact: I cannot implement what I set out to implement today ('H' in unpack) without solving the question you helped me ask earlier (how to get the UTF-8 bytes out of a given character). 20:37
perl -e 'print unpack("H6", "☺"), "\n"' # gives e298ba 20:38
moritz_ masak: didn't you have an UTF-8 encoding/decoding hack in November somewhere?
masak moritz_: we had our own ord/chr before they existed in Rakudo. 20:39
Parrot has all this infrastructure for encoded strings. shouldn't this be easy?
I looked at the relevant pdd earlier tonight. it contained an ocean of details on how strings and encodings work in Parrot. 20:40
no specifics on how to get a sequence of bytes, though.
20:44 M_o_C left
moritz_ aye 20:52
just glanced over pdd28 too 20:53
no informations on the PIR interface at all
masak all this infrastructure, and I'm not authorised to look at my data. 20:54
it's the modernist nightmare.
moritz_ src/string/encoding/utf8.c has to to_encoding function 20:55
s/to/a/
masak a glimmer of hope!
masak looks 20:56
Tene My girlfriend just sketched out a proposal for a rakudo logo, based on Justin Simoni's proposal to use Gimel: pleasedieinafire.net/~tene/logo/gim...archy.html
masak is currently getting well-deserved flak from viklund for the shortcomings of Proto
Tene: cool. very anarchistic. 20:57
Tene That's the idea.
moritz_ aye
masak sort of a cross between a Haskell lambda and the anarchists' symbol.
Tene The gimel proposal was www.nntp.perl.org/group/perl.perl6....sg938.html 20:58
moritz_ masak: look at t/op/string_cs.t... 20:59
Tene She asked me to emphasize that it's a very rough sketch. :)
moritz_ masak: it uses a file handle ($P0, line 499), and then sets $P0.'encoding'("utf8") 21:00
masak Tene: tell her '+1' from me.
jnthn back from the shops - ran out of candy
moritz_ masak: and then prints to that handle
Tene candy++
moritz_ masak: so if you can do that for an arbitrary IO object, and get the bytes from that... you're done 21:01
masak \o/
moritz_: very cool. will you help me do that? viklund is still grinding me about Proto design...
moritz_ masak: I'm doing my best 21:02
masak "We do what we must because we can."
jnthn tries to work out wtf is wrong with his attempt to do //= correctly... 21:03
Tene jnthn: feel free to nopaste 21:04
jnthn oh typo 21:05
moritz_ looking at rakudo.org/2008/12/rakudo-now-suppo...e-pir.html - how do I access Perl 6 variables from PIR? 21:08
or parameters, at least? 21:09
jnthn $P0 = find_lex '$thingumy'
Where $P0 is the Parrot register that you want to put the variable in.
moritz_ thanks 21:10
jnthn Remember to do assignments to variables call
21:10 Woody2143 joined
jnthn 'infix:='(target, source) 21:10
moritz_ ok
jnthn *not* target = source in PIR
skids jnthn: that would mean no need to "box" right?
jnthn skids: It'd probably mean binding rather than assignment. 21:11
But it depends. ;-)
(On the types of target and source)
skids moritz_: figure it all out for us and use every construct even if you don't need to. Once there's an example in setting we can all just copy off you :-) 21:12
moritz_ skids: ;-) 21:13
masak skids: that's what I was thinking also. :)
moritz_ I'll try to do uc in Perl 6 + embedded PIR 21:14
then on to masak's problem
masak great.
masak needs to go home and sleep soonish
but will backlog.

masak jnthn: wohoo!
jnthn (Well, you filed rakudobug... ;-))
masak aye. 21:16
I remember it as if it was yesterday.
jnthn I'm re-doing //= along the way, and putting in &&= too.
(Getting the short-circuit semantics right...)
masak sounds great.
skids drive time & 21:17

moritz_ most Perl 5 test files contain at least 200 tests
I've got a patch for Str.uc in setting 21:21
spectesting now
Tene I'll post to the list after she does another few revisions.
moritz_ nopaste.snit.ch/15903 review welcome 21:22
jnthn moritz_: I don't mind it being large. 21:23
masak moritz_: looks good to me.
moritz_ jnthn: what do you mean by that? could it be done much shorter? 21:24
masak moritz_: no, he was talking about assign.t
moritz_ ah
masak moritz_: why the '$P0 = $S0' step? 21:25
moritz_ masak: because it doesn't work otherwise
masak moritz_: good reason.
moritz_ masak: it's cargo-culted from any-str.pir
masak ah. 21:26
I guess it boxes the string in a PMC or sump'n.
moritz_ it'll probably be parrot string vs. Perl 6 Str 21:27
and the latter is a PMC, yes
could anybody please spectest that? I get some segfaults here, but I don't think they are new 21:28
jnthn moritz_: Yes, was talking about assign.t :-) 21:29

TimToady I've added in "constant pi = 3;" and "constant Num pi = 3.1;" to STD, checking it out now 23:02
jnthn TimToady: OK. They are certainly staying? :-)
TimToady: I guess good compilers are expected to inline them? 23:03
But in reality an implementation that makes them read-only is sufficient.
23:04 frooh left
TimToady yes, the compile is free to poke the actual constant value in directly, as with $?LINE and such 23:05
*compiler
jnthn OK. :-)
moritz_ are things like 'constant pi = $variable' allowed?
TimToady yes, if $variable is known at compile time
inits on declarators happen at the time defined by the declarator (see state) 23:06
or has, for that matter
