Morfent inb4 it's some obscure libidn2 bug 00:02
00:03 rvhausen left
Morfent is there a way to create a list of multi subs through some form of metaprogramming? 00:06
the only way i can think of is eval but i'd rather that be the last resort 00:07
lizmat m: my &a := sub { say "foo" }; a() # like this ? 00:08
camelia foo
Morfent i mean like
i have a list of method names 00:09
the c functions they write are identical in how they work
00:10 llfourn joined
lizmat m: class A {}; BEGIN A.^add_method( "a", method { say "foo" } ); A.a # like this ? 00:10
camelia foo
Morfent that's not quite what i mean 00:11
lizmat Morfent: then I hope someone else will be able to help you, as I'm very tired and it's time for me to get some sleep 00:12

MasterDuke Morfent: can you explain in a little more detail? 00:21
Morfent alright 00:23
so i'm porting Net:DNS from perl 5
but i need to port its dependencies as well 00:24
once of them, Net::LibIDNS2, has some subroutines to convert string encodings between utf8, local, utf32 00:25
only probablem is afaik there is no utf32 support yet, which i'll have to work on myself 00:27
00:27 Actualeyes joined 00:28 sena_kun left
Morfent i'd rather not use ``CArray[uint32]`` to deal with utf32 00:28
00:30 lookatme joined

Morfent are there any plans on implementing utf32 supporting?

Morfent for a c library port i'm porting to perl 6, i want to be able to access macro values, but that can't be done with nativecall on its own. would something like makeing a build script to compile a c library that does not export some header macros that i need. is it bad practice to overwrite macros and redefine them as extern constants? 01:42
s/that does not export/that exports/g 01:44
01:44 TimToady joined
Morfent i'm debating ditching the idea of Net::LibIDN2 being a port of the perl5 port 01:50
there are a lot of features in the library that are not exposed, like some of the features from libidn 01:51
but are useful
01:52 jeromelanteri joined
lookatme The macro not exists in dynamic library :) 01:52
If you want access macro, I think you can write some help function in your help library, like: github.com/araraloren/Net-FTPlib/b...plibhelp.c 01:54
I write a test function test if __UINT64_MAX defined 01:55
Morfent i'll run a test
if there a simple way to compose functions in perl 6? 01:58
i haven't worked out how to do it like i would in js (yeah, yeah, i know) 01:59
comborico1611 Goodnight.
lookatme compose function ?
comborico1611, good night!

Morfent unrelated to the convo, but i ran into a bug with dns resolution for simple http requests 02:21
02:22 Zoffix left
Morfent i'm praying it's not because i fucked up resolve.com, but the code i wrote works fine in ubuntu with the same dns settings 02:22

TimToady not running a proxy, I presume 02:24
Morfent nope
TimToady sometimes has to drop his vpn to get sane address resolution...
Morfent i don't run a vpn 02:25
i tested dns resolution in node and had no problems with it 02:26
though i don't trust node from my experience with it
from when i tried to debug it, i narrowed down what could be making dns resolution to fail 02:28

Ven`` m: (0, (|"0123".comb>>.Int) Xor 2).perl.say; # geekosaur
camelia (2, 2, 1, 2, 3).Seq
geekosaur and the shift in type causes the shift in behavior somehow
10:48 zakharyas joined
geekosaur hm, then prec of or (or X metaop is screwing with precedence unintentially) 10:48
unintentionally
mienaikage All I can say is, needs more unicode 😉
geekosaur which seems like it might make more sense (insofar as it makes any sense at all...) anyway
Ven`` I really don't understand, though. 10:50
scimon: code-golf.io counts in characters, not in bytes?
scimon It does.
Ven`` :\ That's bad.
scimon Which is awesome and gives perl6 even more super powers.
mienaikage You might spot a hint in docs.perl6.org/language/operators#infix_... 10:51
Ven`` I'm going to keep believing counting bytes is the proper way :).
geekosaur I am guessing that it's somehow (despite the slip, possibly it's applying it at the wrong level?) getting a list of lists instead of a single list at the Xor and this is changing the behavior. why, I don't know. it smells fishy but might be a DWIM/WAT 10:52

wander When people talk about "Programming language", they focus more on the *Programming* part. 13:40
But when it comes to Perl 6, *Language* might be more important. 13:41
In other languages, if you ask counting the "length" of a List/String, what jumps out is, hmm, first set a counter, such as i, to 0, then run a for-loop, blablabla...
In Perl 6, the precedure will be, should I use .words, .bytes, .chars or .elems, that is, to choose a proper *word*.
Quite interesting to me.

Morfent i asked a while ago, but does anyone know how to deal with encoding when wrapping c libraries? 16:09
mainly with strings c functions return encoded in whatever the system's locale is 16:10
16:12 Sgeo left
Ven`` Morfent: you mean uselocale()? 16:14
Morfent not quite
16:15 Sgeo joined
geekosaur Morfent, as I answered yesterday, the documented stuff is not yet implemented by moarvm 16:15
Morfent ahh 16:16
sorry i missed your answer
geekosaur you will need to deal with locales manually and you will have to deal with both the internal names moarvm uses and moarvm's shortcomings in mapping the result (those ??? you got)
which probably means this is not going to work very well at all, until someone implements proper locale support in moarvm
Morfent i have moar and nqp's source downloaded
geekosaur and then updates nqp and rakudo to use it 16:17
...that said, if someone does do that work, it'll amount to reimplementing the functions you are trying to use anyway :)
kinda catch-22
I *think* you might be able to cheat and use buf8 instead of Str 16:18
Morfent the parts of libidn2 i'm interested in are for porting net::dns later on
timotimo you know you can set "is encoded" in signature and return value?
Morfent yeah
geekosaur that still runs into issues
Morfent that didn't work
geekosaur moarvm was 'decoding' upper characters as ? instead of iso8859-1 16:19
Morfent YEAH
that's what i was running into
geekosaur and apparently hung after that
timotimo oh? that seems weird
can you turn that into very short code?
geekosaur suggesting there's several bugs somewhere
16:19 Sgeo left
Morfent gimme a sec 16:20
timotimo m: "hellö".encode("latin-1").perl.say
camelia Blob[uint8].new(104,101,108,108,246)
16:22 Sgeo joined
geekosaur m: "hellö".encode("latin-1").decode('latin-1').perl.say 16:22
camelia "hellö"
geekosaur hm
that roundtrips at least
so wither 'is encoded' is wrong, or you used the wrong encoding and it assumed ASCII-60 for some reason 16:23
Morfent shit i forgot i was in the middle of rebuilding perl
sorry if this doesn't run hastebin.com/azeperiyok.pl 16:26
"sub _idn2_free(Pointer) is native { * }" should be "sub _idn2_free(Pointer) is native('idn2') { * }" 16:29

rvhausen Just installed rakudo-star-2017.10 on CentOS. "Use Foo" takes over 1 minute to load, where Foo.pm contains nothing but "unit module Foo;". This can't be right 16:51
timotimo interesting! let's try to figure that out 16:52
can you run that with the env var RAKUDO_MODULE_DEBUG=yes set?
rvhausen 1 RMD: try-load 1946C31AEEF030DB495B0E13AD1403E9CB0AA7A2: /home/barkerj/Moo.pm6 16:53
1 RMD: Trying to load 1946C31AEEF030DB495B0E13AD1403E9CB0AA7A2 from /home/barkerj/.precomp
stalls on that 16:54
(I renamed Foo to Moo)
mspo strace it
how much stuff is in your .precomp dir? 16:55
timotimo strace is a good idea. maybe first run it with "time" so we can see if it perhaps spends ages in the kernel for some reason
or waiting
16:57 abraxxa left
mspo strace -fr 16:58
and maybe -o trace.txt
ilmari -Ttt can also be handy 16:59

rvhausen Only 1 file in .precomp. I strace'd it, but the output is beyond me 17:04
Morfent geekosaur working locale support in might actually be neat
geekosaur rvhausen, you'd want to put it up somewhere so someone with internals knowledge can look at it 17:05
Morfent, it would, but you might also recall I commended on problems making it work nicely on Windows
Windows handles (the character set part of) locales via code pages, and they don't map nicely to unix-style locale names 17:06
17:06 silug left
Morfent hm 17:06
that's a challenge
geekosaur (they also don;t map very well to things like this, because a code page is an attribute of an I/O device, not a string/parameter) 17:08
lots of nasty complications 17:09
Morfent despite all the problems i think it'd be really interesting to attempt to work out 17:14

mienaikage It's a vim plugin which can autocomplete unicode names to characters 17:59

perigrin just has a decently programmable keyboard 18:17

rvhausen Yep, it's gone. :) strace -o trace.txt -fr ./test.pl 20:33
timotimo OK and what does test.pl look like? 20:34
rvhausen I didn't set a lib path, just did "use lib '.'"
use lib '.'; use Foo; 20:35
timotimo OK, what path did you run perl6 from?
rvhausen It's within my home dir 20:36
timotimo hm, OK, do you have a Foo.pm or Foo.pm6 there?
rvhausen yeah, it loads fine, but always after 60+ seconds 20:37
timotimo nothing but "unit module Foo;" you said?
rvhausen correct
timotimo right
having a big library folder is a Very Bad Idea, it seems
and since you're using your entire home, apparently including a symlink into /opt somewhere, as your lib folder, that's extremely big 20:38
i'm not sure why we're scanning the whole folder that you "use lib" with, but at the moment we do
rvhausen Ahhh, yeah, it looked like it was scanning the entire server, haha

timotimo we're literally looking for every readable file and we sha1 them all together to figure out the state of the library folder 20:41
i.e. did anything change since we last precompiled stuff
it only considers files that match perl6 identifier rules, though, so there's that i guess? 20:42
rvhausen ok, I moved Foo.pm into a different dir, set PERL6LIB, and voila, all better
timotimo i wonder where we should document that 20:43
you might also want to rm -rf the .precomp folder that rakudo will have created in your home
