ugexe i dont think so. grepping the kept promises 00:00
raydiak yes grepping currently (erroneously) breaks laziness if I'm not mistaken
ugexe ah. i dont suspect its a bug though. i remember seeing it on one of jnthns slides in an example 00:02

raydiak okay, the .allof(@promises) is running before $p2 is pushed...and $p never does get pushed...so awaiting on .allof(empty list) never returns I guess 00:07
except that makes no sense with grep fixing it 00:12

raydiak danstoner: works here; how old is your rakudo? 00:59
danstoner This is perl6 version 2015.02 built on MoarVM version 2015.02
raydiak that's why
danstoner I should download the whole next version of rakudo? I didn't see a way to do an upgrade with panda. 01:00
raydiak nope there isn't
danstoner ok thanks! 01:01
raydiak you're welcome :)
if you use rakudobrew it can build the very latest version and reinstall the modules you had installed before (once you're already using it), but don't think it works on windows 01:03
ugexe it did the last time i tried 2 months ago

danstoner I'm on Linux (Ubuntu) 01:14
rakudo star 2015.03 build process seems to be confused since I already have 2015.02 moar 01:16
Building NQP ...
/usr/bin/perl Configure.pl --prefix=/usr/local --backends=moar --make-install
Found /usr/local/bin/moar version 2015.02, which is too old.
That's after I do:
sudo perl Configure.pl --gen-moar --prefix=/usr/local/ 01:17
from the extracted 2015.03 directory
I actually first tried: $ sudo perl Configure.pl --backend=moar --gen-moar --prefix=/usr/local/ 01:20
timotimo oh, directly into /usr/local 01:21
i have a special "install" folder that i use as the prefix so that i can sometimes just throw it away completely 01:22
danstoner Heh. I moved /usr/local/bin/moar out of the way and then it built and used 2015.03 version.
raydiak idk if that'll be new enough for the feature you're missing but we'll see 01:23
danstoner is there a proper "uninstall" then for 2015.02 ?
timotimo nope 01:24
danstoner brb, looks like build is working....

raydiak yes please...we usually just gist it on github but whereever we can see it is fine 01:38
01:38 Akagi201 joined
danstoner The latest (30 hours ago) thing... same kind of .tar.gz as the release bundle? 01:39
raydiak nope... github.com/tadzik/rakudobrew
danstoner raydiak: thanks. I'll either look at that or wait for next rakudo star release. 01:41
p.s. panda needs a --version option
raydiak it's very easy, just clone rakudobrew into a dir (usually ~/.rakudobrew), put its bin/ in your path, and run 'rakudobrew build moar' whenever you want the latest everything 01:43
yes we are in a phase where we're working through many questions of deployment like versioning etc 01:44
(oh you'll want a rakudobrew build-panda after "build moar" the first time, too) 01:45

timotimo i don't see a reason for there to be any lazyness in there; perhaps sink-related things instead? :\ 02:54

FROGGS TimToady: /<foo>/ is always about regexes in scope (or methods of the current cursor), but never about subs, right? 17:38
17:38 pochi left, pochi joined
FROGGS TimToady: for example, I think this is invalid: github.com/perl6/roast/blob/master...kets.t#L52 17:39
TimToady yes, that's invalid, but you could write it validly by having a Cursor as the first argument, and returning a Cursor 17:41
FROGGS TimToady: so a subroutine which takes a Cursor would be valid?
because we do not consider subs at all atm 17:42
TimToady m: sub try(Cursor $c) { say "HERE"; $c }; 'foobar' ~~ / foo <try> bar /
camelia rakudo-moar 240cf0: OUTPUT«Method 'try' not found for invocant of class 'Cursor'␤ in block <unit> at /tmp/GqeHcgWkPr:1␤␤»
timotimo that sub isn't annotated to return a cursor, though
should it be considered?
TimToady hmm, I would argue that should work
FROGGS and if subs are preferred over Cursor method this would surprise a lot of ppl me thinks 17:43
TimToady m: sub try(Cursor $c --> Cursor) { say "HERE"; $c }; 'foobar' ~~ / foo <try> bar /
camelia rakudo-moar 240cf0: OUTPUT«Method 'try' not found for invocant of class 'Cursor'␤ in block <unit> at /tmp/buEb88qEOV:1␤␤»
timotimo hopefully they would not be preferred
TimToady there can be no cursor method there
we aren't in a grammar, and // doesn't see the current grammar if there were one
FROGGS m: grammar G; use Test; rule TOP { <ok> }; token ok { 'ok' }; say G.parse: 'ok' 17:45

TimToady we should probably recognize subs that take a Cursor as the first argument, and ignore the others
we allow methods in places of regex, so it seems fair to also allow (some) subs 17:48
FROGGS I guess the only thing that makes me worry is that this would be the first spot where we would do such a thing 17:49

[ptc] has something changed recently with how hashes and arrays work that I've missed?
lizmat [ptc]: just as in P5 (but this happened only very recently)
masak [ptc]: no. it was always like that.
[ptc] some of the examples tests have stopped working and I'm trying to work out why
jnthn MoarVM used to maintain insertion order
JVM never has
masak [ptc]: hashes give no ordering guarantees.
jnthn MoarVM no longer does
[ptc] aha, that'd it be it
jnthn It was an accident that Moar did rather than intent.
[ptc] yeah, hashes don't give ordering guarantees, I know that from P5 20:33
jnthn Or rather, we choes a hash library that happened to do it that way.
And only recenlty got around to ripping it out.
*recently
(Which saves a good bit of memory :))
20:33 colomon joined
[ptc] however, jnthn's comment about moarvm's behaviour explained why it used to work the way it did 20:33
that's good it's changed, that way my expectations about hashes are consistent across languages :-) 20:34
masak which shows how dangerous it is to silently give people hash ordering :)
[Coke] bartolin++ # rt cleanup.
[ptc] yup :-)
timotimo: the tip with .pairs is a good one, I'll try it out
masak JavaScript hashes^Wobjects also guarantee insertion order. and that's also basically because early implementations did, so they're forced to preserve that behavior.
[ptc] also, didn't the repl support readline up until recently, or am I just more crazy than usual? 20:35
e.g., I'm sure I used to be able to edit my input and go to previously executed lines
jnthn [ptc]: afaik it still *can* but that support is now implemented in a Perl 6 module 20:36
[ptc] I updated my moarvm/nqp/rakudo stack today and am tripping over some stuff
jnthn: do you mean in linenoise?
jnthn [ptc]: No, I mean the binding to linenoise (or maybe readline? dunno) that's now used by the REPL is a Perl 6 module using nativecall, rather than having to put that stuff down at the VM level. 20:37
[ptc] m: my %blah = "a" => 1, "b" => 2, "c" => 3; for %blah.pairs.sort(*.key) -> $key, $value { say "$key: $value" } 20:38

jnthn 'cus sub-signature forces a bind check
lizmat aha, so from a performance point of view, a bad idea...
skids sneaky b2gills++
jnthn Yes, if your goal is optimizaiton it's not what you're looking for 20:53
lizmat yeah... ok
jnthn Better leave it as it is and hope spesh is smart enough to do away wiht it
It already does away with most *%_ related allocations if it finds them unused.

if someone wants to have a look, it seems like DIVIDE_NUMBERS allocates 1991776 Scalars in raiph's recursive thingie 21:39
going to figure out how often that's called right now

timotimo hm, not terrible
i meant rindolf, not raiph 21:42
jercos When no one was looking, Lex Luthor allocated 40 scalars. That's as many as four tens! 21:43
timotimo what a jerc!

maybe we'll invent a trigonometric function "jer", so that you can be jer-cos?
