ShimmerFairy .tell TimToady one thing about 'is raw' is that it's just one letter (and visually similar) to 'is rw', and I'm not sure if having such different behaviors be so close in name is a good idea (even worse, 'a' neighbors 'w' on QWERTY, so accidental 'rw'->'raw' is possible too if your fingers slip a bit :P) 00:42

TimToady an array itemizes its elements, so flat can't work directly on an array 05:34

TimToady though perhaps Array.flat could imply deitemization of the elements 05:34
05:38 tokuhiro_ left 05:52 n0tjack joined 05:57 n0tjack left
ShimmerFairy TimToady: you could generally characterize .flat as "treat each Positional item as though it were really a Slip" if you went with that, I think. (That is, [1, [2, [3, 4], 5]].flat -> [1, |[2, [3, 4], 5]] -> [1, 2, [3, 4], 5] 06:01
TimToady well, but flat is recursive ordinarily 06:06

nine .tell TimToady I guess our disagreement comes from me just not seeing the performance penalty. If I don't store a Seq into a variable and .cache (previously .list) it, all that changes is that an additional reference to the new List is stored in the Seq that's gonna be collected anyway in the same GC run as the list. Persisting the Seq however only makes sense if I intend to call .cache on it again later on. 08:48
yoleaux nine: I'll pass your message to TimToady.
nine .tell TimToady But I'll stop arguing now. It may still be a tiny bit faster to avoid storing the reference and I lack experience with the new semantics to back up any claims to lower usability. And it's not that important a topic anyway :) 08:49

well, we still have some SOEs even after the "don't check the SC" hack, but maybe OSX does something a tad different somewhere...

1 Aug 2015 00:17Z <psch> ab5tract: as for non-jdk interop, you usually need to supply :jar<$jarfile> to the use statement

camelia ( no output )
lizmat feels to me $obj.Capture in the unpacking sense, should maybe be called something else
skids But [[1,2]] is not identical to [$[1,2]].
benzen can i know if this ^^^ is a bug? 19:56
timotimo that's single-arg-rule, skids, right?
skids It is, but we need a word for what $ does there other than "itemize"
lizmat jnthn: anyways, I ran into this yesterday working with BooK on a Perl 6 version of Git::Repository
timotimo skids: [..] itemizes its contents, $[...] itemizes the container as well
jnthn skids: Why? 19:57
skids Because it's hard to describe t people.
jnthn skids: Calling the same operation two different things will surely confuse them.
FROGGS benzen: aye... though I was under the impression that I fixed that just lately :/
benzen shouldn't it print "last" even if it skips with next?
jnthn lizmat: Why?
FROGGS benzen: yes 19:58
lizmat one of the options you can give in Git::Repository, is a list of options to give to git
jnthn lizmat: I'd hope folks aren't using Capture itself all too often.
benzen FROGGS: oh, didn't know it was already noticed.
lizmat something like git => (foo => bar, baz => 42)
19:58 telex left
benzen it's is wuite some time (like 2 weeks) since i first saw it 19:58
FROGGS benzen: no, it wasn't noticed, it just happen that it was temporarily not implemented because of a refactor 19:59
lizmat jnthn: basically, you specify the parameters to an internal sub
19:59 telex joined
FROGGS benzen: and I fixed that, but obviously not good enough 19:59
lizmat jnthn: the idea was to give the named param the following signature: Capture() :$git
moritz jnthn, lizmat: a big problem (IMHO) is that some docs still say that Capture fill the ecological niche of a reference, so many programmers familiar with references try to use them 20:00
timotimo urgh, that's bad
moritz wheras I'd argue that scalar containers are closers to references
timotimo aye
lizmat jnthn: if you pass a List, the coercion to Capture works fine
moritz and even though one can argue that it's still true, it simply not a helpful comment for the user 20:01
lizmat if you pass anything else, like git => (foo => bar)
colomon where is the grammar construct defined in rakudo?

colomon FROGGS: no, that’s just where the methods for it are. 20:02
FROGGS colomon: what are you searching for then?
jnthn lizmat: I don't think we've *ever* made the claim that \(foo) and foo.Capture are the same
colomon FROGGS: wanted to see what it looked like
FROGGS colomon: the keyword definition?
colomon FROGGS: yes

15:29Z <nine> [Coke]: With rt.perl.org/Public/Bug/Display.html?id=111720 I'd argue, that the current behavior is correct due to the one item rule. Array.new(@a) essentially creates a copy of @a. Thus changing @a will not affect the new array.

cschwenz when doing testing and you have a plan $numtests; , the docs say done-testing isn't needed. is it still a good idea to have done-testing at the end of the test file? 20:21
20:21 benzen left
nine jnthn: I wrote an iterator for ArgFiles based on your IO::Handle::lines. Gives us a 3.4x speedup but it seems to have uncovered a bug: a newline at the end of a file gives us an empty string in the last iteration. I don't think it did that before. 20:21
[ptc] cschwenz: done-testing is only needed if you don't want to specify the number of tests at the beginning (e.g. when the test suite is initially being developed) 20:22
yoleaux 9 Sep 2015 14:27Z <itz> [ptc]: 99problems.t is more like 999glr-problems.t :)
15:59Z <moritz> [ptc]: I've updated the rakudobrew on hack in /home/rakudobrew to a pots-glr rakudo (+modules); please check if the examples.perl6.org rebuild still works
jnthn nine: oh, hmm

20:23 telex joined
cschwenz so, plan 42; XOR done-testing; 20:24
[ptc] cschwenz: I'd also like to echo what jnthn said. It's more of an either/or thing
cschwenz: it's the same situation with Test::More in perl5, either one uses done_testing (e.g. if one is in the process of adding lots of tests), or there is a stable number of tests in which case one should use a specific test plan 20:25

timotimo laben: i suggest using something metadata-driven to bind Qt rather than manually going at it 21:37
FROGGS my highest priority is to get the name mangling on osx right, which just seems to be a matter of a underscore 21:38
21:38 telex left
laben yeah, that's probably a better approach given its size 21:38
timotimo i forgot what it's called, but there's something like a DB that you can query via regular C function calls that should give you everything you need to build a binding

necrophcodr after searching a few around duckduckgo and google, only to find no real answers, i have come here. is there any way to easily compile perl6 or nqp to mast, using the moarvm backend with rakudo? 22:05
FROGGS necrophcodr: yes 22:06
necrophcodr FROGGS: how?
FROGGS perl6 --target=mbc --output=Foo.pm.moarvm Foo.pm
necrophcodr ah, the target is mbc
FROGGS yeah
necrophcodr i first caught on that it would be "post", then later "mast". neither of which of course worked. thank you so much! 22:07

no, it's not The Big One; the loop inside it is.

22:42 n0tjack joined, rindolf left
ShimmerFairy skids: I think it has a lot of potential for quite nicely pulling values out into another, non-flat structure. :) 22:43

timotimo "%~dp0rakudobrew" this looks strange to my non-powershell-understanding eyes
patrickz If anyone wants to give it a try, please do! I can't fully test myself (build ist currently broken for me on Windows due to some other bug). 22:54
@timotimo: Typo is fixed.
That strange line actually *is* tested and works. 22:55
%~dp0 is the path (without filename) of the current script (%0 + ~dp modifiers)
The / is already appended so it looks rather strange by sitting directly next to the "rakudobrew", but it works. 22:56
timotimo mhm

timotimo jnthn: from the spesh log of the native variant of that benchmark i can tell we're not inlining many very simple subs like &infix:<+>, &infix:<->, &infix:</> and &infix:<*> 23:17
ugexe nice. missing an important (to me anyway) part though... downloading rakudo and friends itself instead of being packaged into the module
timotimo jnthn: could this be due to something along the way not understanding regref? 23:18
leont That should not be that hard
timotimo jnthn: not even postfix ++ is inlined :( 23:19
leont HTTP::Tiny ships with perl5 nowadays (5.14+ I think), and untarring has been supported even longer
23:19 khw joined, salv0 joined, inokenty joined, n0tjack left
ugexe right. i imagine if i did it i'd probably just use Alien because it handles all that. and having it on cpan you might as well not worry too much about staying strictly core 23:20
