grondilu that looks LTA
though it'd be very easy to make a module. 00:45
perlawhirl yeah, that pseudocode in the wikipedia article just needs some 'my' and '$' thrown in and it's almost good to go 00:46

grondilu the wikipedia page should give a numeric example where there is a problem with the naive implementation.
timotimo yeah 00:57
grondilu mentions it in the talk page. 01:01

geekosaur l is long double 01:14
hypot is double
grondilu isn't long double num64?

geekosaur long double is 80 bit on intel
grondilu ok
geekosaur m: use NativeCall; sub hypot(num64 $, num64 $) returns num64 is native {}; say hypot 3e0, 4e0
camelia rakudo-moar 447d59: OUTPUT«5␤»
scott cppreference says "long double - extended precision floating point type. Does not necessarily map to types mandated by IEEE-754. Usually 80-bit x87 floating point type on x86 and x86-64 architectures."
geekosaur yep
timotimo there's also long long double 01:17
but on MSVC++, a long double is 64bit
unless you give it some flag
scott I've never heard of long long double 01:18
only float/double/long double and char/short/int/long/long long
timotimo i've been fascinated by extra-long floating point types for a few weeks 01:19
geekosaur long double is nonstandard, as cppreference implied. msvc "supported" it as an alias for double, then finally when they added their own extended precision double had to invent long long double 01:20
scott lol
timotimo en.wikipedia.org/wiki/Extended_precision
geekosaur (msvc's behavior there caused much gnashing of teeth among numeric methods types, because it silently didn't provide the precision everyone expected) 01:21
scott actually, I still can't find google results for "long long double", even MSVC-related
geekosaur www.google.com/webhp?sourceid=chro...0double%22 01:23
need the quotes or google silently drops the second "long" as a duplicate
o.O
www.cplusplus.com/forum/beginner/40003/
geekosaur "long long long double" --- seems to have been a thinko... 01:24
timotimo *shrug*
grondilu that makes me wonder. Are there functions in rakudo that are defined as Native? 01:25
scott geekosaur: I had the quotes, and there is nothing official-looking in those results 01:26
timotimo grondilu: no 01:28
BenGoldberg m: use NativeCall; my $h = sub (num64 $, num64 $) returns num64 is native is symbol("hypot") {*}; say $h(3e0, 4e0); 03:18
camelia rakudo-moar 447d59: OUTPUT«5␤»
BenGoldberg m: use NativeCall; (sub (num64 $, num64 $) returns num64 is native is symbol("hypot") {*}).(3e0, 4e0).say; 03:19
camelia rakudo-moar 447d59: OUTPUT«5␤»
scott why do people write the bodies of native subs as `{*}`? 03:20
ugexe m: class Foo { proto method foo(|) {say 1; {*}; say 3; }; multi method foo { say 2;} }; Foo.foo 03:29
camelia rakudo-moar 447d59: OUTPUT«1␤2␤3␤»
scott I'm not sure how that applies to native calls (was it supposed to?) 03:31
ugexe it works the same way 03:32
scott I tried it with native sub and it said `{*} may only appear in proto` 03:34
I don't see why plain native subs have a `*`
ugexe you are declaring the signature and delegating somewhere 03:35
scott it also works without the `*`
as far as I can tell 03:36
in fact the body generally just seems to be ignored
andrzejku hello :) 05:46

yoleaux 23 Sep 2016 22:22Z <jnthn> nine: About your question about wrap of a core method in backlog, you'd better stick "no precompilation" on your code if you do that, since it's a monkey patch and those don't compose under precomp.

TimToady well, :{} is gonna make a hash or a closure for the value, which is odd 15:26
TimToady :[] actually makes a list, but it knows it can handle a list, especially when you need multiple delims 15:28
as for :(), I have no idea what it's thinking there, since there's nothing to invoke 15:29
well, no, it's not invoking, so those are just grouping parens, like foo => (1,2,3)

hackedNODE Of course, we can enable it temporarily, open just some Hacktoberfest issues, and then close it at the end
hackedNODE isn't sure that's worth the effort
moritz no, we should just do it for other repos 18:57
docs, roast, website, you name it
nwc10 those might also be easier for new folks to contribute to 18:57
ooh, finally, live is live 18:58
hackedNODE First Hacktoberfest issue done: github.com/perl6/roast/issues/161 19:04
I guess all LHF in docs repo can also be that
hackedNODE marks 19:05
zengargoyle LHF? 19:07
[Coke] Low Hanging Fruit 19:07
zengargoyle ah 19:15
ugexe Inline::Perl5 + DBIx::Class + runtime generated schemas (package App::DB; use base 'DBIx::Class::Schema::Loader') is pretty nice for prototyping 19:29
dalek line-Perl5: ab7ce57 | niner++ | lib/Inline/Perl5.pm6:
Remove unused optional argument
 19:30
nine ugexe: :) 19:30
ugexe I guess I see why, since some perl6 modules have .pm extension and would then see packages in perl 5 that should not exist 19:37
nine ugexe: having both in the same tree might not be a good idea because the .pm extension is ambiguious
Woodi_ is it possible to hang some station half-way to Mars ? for emergency or re supply ? 19:38
gfldex Woodi: no because of orbit mechanics it would drive away from it's half-way position fairly switfly 19:38
geekosaur also, earth and mars both move. where do you put it if earth and mars are in opposition? 19:38
geekosaur ...and rescue prospects for that station itself are kinda terrible 19:39
gfldex if you can get the timing right, you could have it at a halve way position for one mission tho
Woodi damn, everything swims :) 19:40
moritz and then what? it's hard enough to reach the half-way point that you can't have a proper hospital there anyway 19:40
hackedNODE moritz: well, I tagged a bunch: github.com/issues?utf8=%E2%9C%93&a...toberfest+ 19:40
moritz or really most of the equipment that you'd use in any kind of rescue mission 19:41
moritz hackedNODE++ 19:41
moritz hackedNODE: thanks a bunch! 19:41
harmil_wk It's turtles all the way down... qww<"{"{"{"..."}"}"}"> 19:45
dalek line-Perl5: e445bab | niner++ | / (2 files):
Save a native call per P5 method invocation

The first argument of a (non-package) method invocation is an object. No need to increase the refcnt before the call just to decrease it again while setting up the arguments on the perl stack.		 19:47
dalek line-Perl5: f05da26 | niner++ | lib/Inline/Perl5.pm6:
Remove unused self argument from invoke

Passing self was probably part of earlier attempts at implementing inheritance. However the parameter has been ignored already and is now gone.		 19:49
senochan Does anyone know how to specify the port to run bailador on? 20:07
[Coke] baile(12345); 20:08
senochan ahh, thanks
El_Che ahaha
bailador is polite
baila -> imperative, regular you 20:09
senochan This is the first time I've used something like bailador, I like it a lot
El_Che baile -> imperative, formal you (vous in french)
ZoffixMobile dogbert17, looks ok, but can be better. I'd use the is-deeply routine instead of just 'is', as that tests using eqv rather than just compare what the two values stringify to 20:25
ZoffixMobile oh... 20:27
ZoffixMobile star: my $list = (1, (2, 3,), "a"); duckmap(-> Int $x { $x ~~ Int ?? $x !! Any }, $list) 20:28
ZoffixMobile dogbert17, I think your block is wrong there. You ask for Int only in the sig, so the ternary will always be true. IIRC your original bug report did not have a sig on the block 20:29
oh, wrong chanmel 20:31

dalek line-Perl5: 101bf73 | niner++ | / (3 files):
Pass back the type of a sole return value from P5 to P6

Use another cheap int32 is rw argument for passing back the type of the return value in the very common case that there is only one. This saves another native call on such function calls or method invocations.		 20:34

( no output )
ZoffixMobile dogbert17, never mind the last point :) ^^ it does hang before the fix :) 20:37

MasterDuke how do i use the --git-depth=<n> option of rakudo's Configure.pl? 23:35
i thought it would just do a shallow clone of nqp (and moarvm?), assuming i also have --gen-moar
