raydiak in a casual test of 1e5 iterations on my old cheap laptop, the regex method took 7s, the bag/junction method took 19s... 00:01
m: say so .elems == .unique.elems given "CasdfghjkC234".comb.list
camelia rakudo-moar 1ab1fb: OUTPUT«False␤»
raydiak ...and ^ took almost 3s
00:05 pierre joined
geekosaur huh. I was playing with something resembling that 00:07
I would have expected the Bag to be faster though. (optimization opportunity?) 00:08
00:10 pierre left
AlexDaniel raydiak: what about 00:11
m: say [==] 1, |‘abcde’.comb.Bag.values 00:12
camelia rakudo-moar 1ab1fb: OUTPUT«True␤»
AlexDaniel m: say [==] 1, |‘abcdce’.comb.Bag.values
camelia rakudo-moar 1ab1fb: OUTPUT«False␤»
AlexDaniel raydiak: how long does that take? Perhaps junction is making it slow
raydiak ouch...idk, it's still trying :P 00:13
AlexDaniel :( 00:14
raydiak oh, my bad, I was using 1e4 iterations the whole time. it took 17s 00:15
AlexDaniel so, faster than junction, right? :) 00:16
but yeah, then .unique is the way to go I guess
raydiak by less than 10% but yes :)
m: say so 'CasdfghjkC234'.comb.repeated; say so 'Casdfghjkc234'.comb.repeated 00:24

kalkin- Why can't I do subset MyType of Str where *.comb.repeated and *.chars >= 16? It always just evaluates the first condition 00:40
geekosaur reuse of * doesn't work like that 00:41
something like $^a may work better?
kalkin- geekosaur: the per6 documentation doesn't find anything if i search for $^ 00:42
geekosaur more specifically, each * refers to a distinct parameter

But just to clarify, when would it be usefull to use * in a subset where?
AlexDaniel … never? 00:47
kalkin- hmm, where did i pick it up? 00:48
AlexDaniel not that it doesn't work, it does. But I am not sure why would you want to use it 00:49

Zoffix Are there any tricks for starting a process outside of "current environment". My puzzle: when my stuff is run with `prove` it runs it in a harness and calling run('tput', 'cols') always returns 80. I want it to somehow give me the actual value of the actual terminal. Any tricks? 03:28

geekosaur might try removing COLUMNS and LINES from %*ENV? 03:32
ugexe you can pass in :$env to run, so combine with ^ 03:33
geekosaur otherwise it may be using a pty, and good luck finding the original tty in that case
awwaiid TEttinger: StrangeLoop is an amazing and awesome conference, and the Perl 6 communit should be ALL over it, but somehow isn't. They typically even have an "emerging languages" track and lots of very very relevant topics 03:35
Zoffix I don't see those set at all. This is my entire %*ENV run under prove: gist.github.com/zoffixznet/a01721c...f8328e775b

geekosaur does not see any indication offhand that prove uses ptys...
03:42 bitmap joined
ugexe youre going to have to get it before prove spawns a new process and set it in an ENV yourself to use inside 03:44
Zoffix Eh, can't do it. Was gonna use it in a test module, but I guess 80-col chars it is. 03:45
ugexe but TAP.pm6 in rakudo might be able to do it better?
Zoffix hm
No idea what TAP.pm6 is all about. I'm gonna table this for another day... 03:46
ugexe its TAP::Harness (prove6) fwiw 03:47
geekosaur "prove" runs tests for the TAP testing harness 03:48
ugexe yeah, and i doubt `prove -e 'xxx'` is helping to make getting the original term width easy 03:53
geekosaur oh, yeh 03:54
unless it opens /dev/tty it will be using $TERM default because stdout and possibly stdin are not terminals 03:55
(otoh there's your workaround to get the actual terminal size)

MasterDuke jnthn: my rakudo pr did include a bump to NQP_REVISION because my nqp commit was accepted first
jnthn Oh...yeah, you'd need to get the NQP one merged first :) 12:50
Though hopefully folks merging PRs do test them some ;)
MasterDuke jnthn: but that commit was then reverted because it broke rakudo as it existed before the rakduo pr 12:51
jnthn Oh...
:)
MasterDuke so they kind of have to happen simultaneously (well, nqp first, but rakudo immediately after)
i probably didn't give a good explanation of the mutual dependency in either pr 12:53
psch MasterDuke: a comment on the NQP PR a la "the resulting rakudo fallout is fixed in rakudo PR #..." would probably have prevented all the confusion :)
jnthn MasterDuke: Probably the best bet is to make that clear in the PRs and then maybe ask someone here or on #perl6-dev
psch MasterDuke: rakudo PR 772 is the one that depends on the merged-and-revert nqp PR? 12:55

pmurias jnthn: is being able to reference a undeclared variable intended QAST sematics? I mean having a QAST::Var.new(:scope<lexical>, :name<$not_declared_anywhere>). 13:19
RabidGravy leaving the whole body but removing the "is Staticish" from the declaration and it still fails
as above but removing the "use Staticish" and it works 13:20
jnthn pmurias: QAST doesn't enforce anything in that sense
RabidGravy however a plain "use Staticish" works
jnthn pmurias: Anything it doesn't find in an outer node it assumes should be compiled into a late-bound lookup and left to fail at runtime
RabidGravy thus I really, really need some new angle of attack on this 13:21
jnthn pmurias: Or to become resolvable at runtime.
(Often via forceouterctx)
RabidGravy or, at option, get the arse with the whole thing and delete the modules from the ecosystem

RabidGravy erm, to be honest I would actually leave it slow rather than cloud the example with an idiom that is itself going to raise questions 15:03
I might add that removing the "use lib" from the example will probably be of some benefit as it prevents precompilation (or did at some point) 15:04
then just change the instructions for running the examples for the uninstalled library 15:05

RabidGravy another one of my modules has just randomly stopped working with 2016.05 16:43
psch well, the whole CUR stuff does suffer from the problem that drove ShimmerFairy away - that is, developed too late, merged too early, still in flux 16:45
i can imagine that's part of what's causing module breakage, since nine is still working on parts of it
RabidGravy no, this is something else
psch did you bisect?
oh, that makes me wonder
does that bisect bot we have now deal with gists? cause that might be nice for big tests, like modules 16:46
RabidGravy it's some previously working thing with a channel, seems to hang on a private futex

RabidGravy AAAAARGH, heisenbug 16:49
it's Audio::Libshout, introducing some instrumentation into the test appears to make it work 16:50

psch so the tests as-is are a test case for the breakage?
RabidGravy yeah
the last time it definitely worked was on Feb 29, may have tested since 16:52
psch hrm, can't run the tests on hack, not easily at least 16:54
RabidGravy yeah this is very timing dependent 16:55
psch no, it's mostly a matter of installing a PATH-wide perl6, installing a module manager, installing the deps...
which probably includes libshout itself

azawawi RabidGravy: modify .travis.yml and run it on different 2016.0x ? 16:57
hoelzro since Perl 6 thinks in terms of graphemes, what's the best way to remove combining characters from a string? 16:59
$s.subst(/\c[COMBINING ACUTE ACCENT]/, '', :g), for example, doesn't cut it
RabidGravy azawawi, personally I'd rather not have any license at all beyond a very vague BSDish kind of thing but my experience of maintaining quite well used P5 modules has made me realise that I can't be arsed with dealing with the lawyers of, e.g., Boeing asking for an explanation of the license

dogbert17 the docs seem to imply that it should be Str
hoelzro dogbert17: it's Str
lizmat Str(Any) actually, I think
because it will stringify 21:26
hoelzro ah, good point!

dogbert17 you're starting to confuse me :) I was hoping to extract enough info to document the method 21:27
lizmat for object hashes, it indicates the type it should have
dogbert17 lizmat: ok 21:28
jnthn For normal hashes too, in terms of the constraining behavior.
But yeah, it doesn't return a coercion type that captures that aspect of things yet.

geekosaur dogbert17, I think lizmat is being confused also (that is, things don't seem to be doing what they're supposed to...)
lizmat that piece of code predates coercion types :-) 21:29
I know, because I wrote it :-) (I think :-)
dogbert17 geekosaur: phew I was beginning to suspect a couple of 'missing' beers :)
dogbert17 they were in front of me and suddenly they were gone :( 21:30
jnthn How does it happen? o.O :) 21:31
lizmat: Any is a reasonable thing for it to hand back, in a way, though. 'cus it still accurately represents the constraint... 21:32
But yeah, the coercion type would be more precise.
lizmat jnthn: we could also return Str(Any)
jnthn Wonder what the spectests say, if anything :) 21:33
lizmat github.com/rakudo/rakudo/commit/1b13351eac
jnthn I'm guessing if you committed it, they're happy? :) 21:34
lizmat actually, I didn't spectest
and looking at the tests, they won't be :-(
jnthn aww
lizmat grrr
dogbert17 lizmat++ that was a fast change :) 21:36
lizmat yeah, looked simple enough 21:37

timotimo P6Weekly has a module now?
hah
22:08 TEttinger joined
ugexe i thought p6w was used to reference Perl6::World as well 22:08
lizmat that usage predates my involvement in rakudo 22:09
timotimo i've never seen anybody refer to Perl6::World as P6W or p6w
22:10 wamba joined
ugexe i've always seen Perl6::World.new saved to $p6w when using Perl6::Compiler 22:10
timotimo huh 22:12
22:13 vendethiel joined 22:18 jjido joined
ugexe when i've seen people invoke Perl6::World in code samples they've always named the container $p6w 22:23
timotimo shrugs 22:24
i've always only worked with it when it was in $*W or maybe cached in $!W or $!World 22:25
ugexe yes, if you are dealing with the current World
timotimo most of my work that has to do with World is either in Grammar, Actions, World, or Optimizer :)

 22:58
jdv79 why would you release goats?
RabidGravy why not? 22:59
jdv79 we had some and when they got out of the pen they just wandered around eating random things jusst like they did in the pen.
just doesn't seem significant
lizmat jdv79: could be they be eating random things that aren't yours ?
jdv79 they try to eat anything from what i remember. they've all died off a few years ago. 23:00
but they even tried to eat coals from a bonfire we had in that pen once. not the brightest creatures ime. 23:01
RabidGravy well when I was about five they tried to eat my vest, and I remember that
jdv79 haha
RabidGravy then when I was twenty or so they ganged up on me in me in a Mountain in northern spain, quite freaked me out 23:03
I've forgivven them obviously, but now they are my my emblem for scary weird stuff 23:04
jdv79 did they try to nibble away at you in spain? 23:05
RabidGravy no I was going up a mountain path and the biggest one jumped up on a rock ahead of me and looked intimidating 23:07
then the rest came round behind
jdv79 nice. i guess they can look a bit freaky to some because they have slot pupils 23:08
