Zoffix ugexe, how come this is catchable but in Proc::Async's case you need the CATCH/default stufF? 00:04

lucs I just did ｢use Foo:From<Perl5>｣, and got ｢===SORRY!=== Could not find Foo.pm in … CompUnit::Repository::Perl5<-122…>｣, which makes sense, because I forgot that I hadn't installed Foo in my Perl5. 02:26
So I installed it, and yet I still get the same error.
Do I need to force something somewhere? 02:27

Zoffix lucs, it's :from, not :From. 02:34
Do you still get the same error when that is fixed? 02:35
I can't reproduce that error with either spelling. What's your Perl 6's version? 02:36
Oh, yeah, it's the :From bit.
lucs 'from' appears to fix it. Thanks. 02:38

geekosaur the fails is correct. "use Bar;" in perl5 also will not look for Foo.pm, but Bar.pm. 03:20
the other... it does look like it's making an unwarranted assumption. then again I don't think it can get that right... 03:22
not without e.g. snapshotting the whole package hierarchy before and after the load to see what it actually loaded 03:23
lucs I'm thinking that it must be relatively frequent for a Foo.pm to have a ｢package Bar｣ within it though (both times I've tried Inline::Perl5, both times it appears to have happened). 03:24

LeCamarade Hello, guys; is there is a Mersenne Twister module anywhere for Perl 6 as yet? 10:10
It seems that srand/rand are not implemented as MT. 10:11
psch LeCamarade: fwiw, the MoarVM backends calls a C function called 'tinymt_generate_double' for nqp::rand_n 10:14
LeCamarade: the jvm backend uses Javas Random class
10:14 Actualeyes left
LeCamarade No, I am on Moar. So that looks good, any TinyMT should suffice. 10:14
Problem is, the numbers do not seem to agree with MT proper. :-( 10:15
psch i'm no number theoretician
how are you testing that? 10:16
LeCamarade Against Ruby's MT. :-/
timotimo if you have a C implementation handy, you can use that via NativeCall 10:17
LeCamarade Of course, the assumption here is that Ruby is Japanese enough to have an accurate MT. It is accurate; it gives the expected series when I seed it with a constant and then run for a constant number of ints. The Perl 6 one, apparently not. I may be using the Perl 6 one all wrong.
timotimo so you don't have to implement it yourself
LeCamarade Isn't NativeCall the best thing since make world?
timotimo it's pretty great :) 10:18
the performance is not as good as it could be, but making it better will require a re-write of how nativecall works on moarvm
10:19 rindolf left
psch m: use NativeCall; sub srandom(uint32 $s) is native {*}; sub random is native returns Int { }; srandom(10); say random; say random 10:19
camelia rakudo-moar 58dc8c: OUTPUT«1215069295␤1311962008␤»
psch that's stdlib, fwiw
timotimo but once that rewrite has happened, you will hardly be able to tell the difference between calling C from perl6 and calling C from C :P
psch but that's not MT, says the manpage 10:20
parabolize LeCamarade: Does this do what you want? github.com/bluebear94/Math-Random/...dom/MT.pm6
psch ...i think
parabolize There is a synopsis in the README 10:22
psch hm, one thing i can see that might throw off the series is marshalling of a double to a Num
like, create.stephan-brumme.com/mersenne-twister/ doesn't generate doubles, but signed ints 10:23
...do we have rand_I?
LeCamarade parabolize may have found excatly what I need.
psch m: use nqp; srand(1); say nqp::rand_i; say nqp::rand_i 10:24

gregf_ wow, NativeCall++ 10:26
does that call c functions directly?
psch ...FSDO "directly"
i mean, we have to wrap stuff around and all
10:26 labster left
LeCamarade Okay, now that I have rememebered to panda search, which I should have done first-thing, I have found the Math::Random that parabolize mentioned, and even a Crypto::Random which I will use later. 10:27
gregf_ psch: ok. in Ruby i can use something called Fiddle to invoke c functions. like so, libc = Fiddle.dlopen("/lib/x86_64-linux-gnu/libc.so.6"); @alarm = Fiddle::Function.new(libc["alarm"], [Fiddle::TYPE_INT], Fiddle::TYPE_INT) 10:28

LeCamarade It worked! 10:52
For posterity, and .away log files ...:
panda install Math::Random 10:53
use v6.c;
use Math::Random::MT;
Zoffix LeCamarade, we have an ecosystem website BTW: modules.perl6.org/
LeCamarade my $rng = Math::Random::MT.mt19937;
Zoffix and modules.zef.pm if I got the url right (same ecosystem) 10:54
LeCamarade After something like $rng.setSeed(27);, the result of the next $rng.nextInt is like the grosser Ruby equivalent that requires an unpack of binary bytes.

DrForr Mersenne twister, I assume? 10:55
LeCamarade Zoffix Thanks. I have only been using Perl 6 for two weeks or so ... Worth the wait!

LeCamarade DrForr yes, MT.
DrForr Party on, it's great to see new blood! 11:00
parabolize bbkr: by default everything rakudobrew installs is under one directory. you clone rakudobrew's source where you want it and add its bin directory to your path 11:02
bbkr parabolize: what I need is to build rakudo on one machine, let's say in /home/x/rakudobrew and then copy /home/x/rakudobrew/moar-2016.07/install to N production machines to /home/x/myproductionperl6 11:05
11:06 TreyHarr1 left 11:07 TEttinger left
moritz bbkr: no, iirc rakudo doesn't support any kind of relation 11:08
*relocation
bbkr parabolize: so I don't want to have rakudobrew on production machines (they even don't have make utils installed) and I need to get rid of original absolute path where build was made
moritz the best you can do is to use fakeroot to build with the same absolute path that you want on the production machines
or patch rakudo and nqp, which would be highly appreciated as well 11:09
bbkr moritz: thanks. I'll try fakeroot.
nine bbkr: rakudobrew is absolutely the wrong tool for the job and unnecessary 11:10
bbkr: rakudobrew is solely for when you really want multiple rakudos with each their own installed modules on the same machine
El_Che just parachuting here: use docker
moritz or a native package for your OS 11:11
nine bbkr: what's keeping you from installing to /home/x/rakudo on your build machine and copy that directory to your production machines?
El_Che imho is docker or native packaging the only proper ways for production 11:12
11:13 pmurias joined, kyclark joined
nine El_Che: so if Perl 6 is used for a maintenance cronjob on those production machines, you'd use docker for installing rakudo? 11:13
El_Che yes 11:14
bbkr nine: path is not relative. so I cannot for example install on production /home/x/rakudo-experiment, run code with this version and then simply rename it to /home/x/rakudo to replace previous one.
El_Che docker run --rm
rakudo is a moving target, if you have more than one program running off the same physical install you get tricky upgrades 11:15
nine El_Che: actually we promise backwards compatibility
El_Che i run something in production with cron and docker (runs once a day)
nine: think of modules etc 11:16
do you want aplications to share modules? etc
moritz it really depends on the infrastructure you already have
El_Che it's a choice with overhaed
nine El_Che: we do support versioning of modules :)
El_Che but worth it in my case 11:17
i like to test apps in isolation
moritz if you have infrastructure for the whole docker zoo, then building rakudo in a docker container is likely the most sensible thing
if you do everything with native packages, you could either have a package for rakudo, or fat-package your application with a copy of rakudo (like dh-virtualenv does for python) 11:18

Psy-Q moritz: oh, ok, didn't know it had its own
R[DaneelOlivaw] I had the same issue :/
moritz Psy-Q: every process has a copy of its environment variables
Psy-Q moritz: i thought it was perhaps inherited from the spawning shell 13:16
but i'm looking through the atom-perl6-editor-tools source now 13:17
moritz Psy-Q: it usually is
Psy-Q: but there are lots of ways to screw up, like applications setting their own PATH, or accidentally spawning the program before PATH is set, or some other fun
like, launching it from a desktop launcher that doesn't start a login shell 13:18
Psy-Q ah, interesting. if started from alt-f2 (in xfce) it does not grab a PATH, but if started from a bash, it does inherit the PATH that includes rakudobrew
moritz: i think that was the issue indeed
i'll have to find out if xfce's launchers can use login shells
moritz bash -l -c 'atom-perl6-editor-tools' 13:19
as the launch command
maybe
Psy-Q hm. with bash -l -c 'atom' it doesn't get it
but from a true interactive shell it does 13:20
ah, i see. /usr/bin/atom is a wrapper script. it does things before actually invoking the binary 13:21
nine Psy-Q: When an interactive shell that is not a login shell is started, bash reads and executes commands from /etc/bash.bashrc then ~/.bashrc when those files exist and are readable. 13:22
from man bash
moritz Psy-Q: you might need to include .bashrc from .bash_profile (or vice versa, can't ever remember that)
Psy-Q maybe i set the paths in the wrong bash config files
moritz or you could try bash -i instead of bash -l
Psy-Q ah! yes, bash -i -c does it 13:23
thanks
i will have to clean up my bash configs and put all my rakudobrew stuff in the correct places

moritz kyclark: you could replace those recursive search calls with callsame(args) 15:41

hahainternet reducing the number or depth of stack frames can have performance advantages 15:42
kyclark I'm also trying to figure how to indicate failure. In Haskell I might use a Maybe Int so that I could return Nothing when not found and Just x when found.

if you put all three statements in one line it works fine. 16:34

lambd0x Hi everyone! I'm currently having some trouble with I/O binary operations. I undestood that now instead of working with a regular str, it's done using a buf type, but how can I think I might be not knowing how to properly work with this type. Can someone what exactly a buf type holds and how to work back and forth with str? 16:59

camelia rakudo-moar 58dc8c: OUTPUT«utf8:0x<66 6f 6f>␤foo␤»
moritz and a buf is just a sequence of integers
lambd0x would an @str work with .encode in the same way? 17:01
moritz what do you mean by @str? 17:03
lambd0x a string held in a variable of such.
moritz @str is an array variable 17:04
so you can say @str[0].encode for example
or $str.encode
lambd0x Because it wasn't working.... might be syntax error...
Yes, I was iterating over its parts and calling it to a buf variable. 17:05
Just clarifying, how is the right way of declaring a buf variable? 17:06
moritz my $buf 17:07
or my Blob $buf

trying to print an array in lines binary basically. 17:59
*binary lines... :P
It's printing but as regular text. So I'm guessing something is wrong in my use of spurt 18:00
R[DaneelOlivaw] lambd0x: what are you printing? 18:01
spurt :bin, "foo", "Test".encode; would show up as 'Test' in the file
dalek c: 574783c | (Wenzel P. P. Peppmeyer)++ | doc/Type/IO.pod6:
spurt got :bin
 18:02
lambd0x something like: $str = "text" to a buf variable after encoding it and passing as argument in the second area of spurt along with :bin adverb
such as: spurt "file.bin", $buf, :bin ; 18:03
R[DaneelOlivaw] lambd0x: well, you're encoding it into utf-8 and then when you read the file (presumably also in utf-8) you'd see "test"
psch m: my $line = "Test"; my $buf = $line.encode; print $buf; # to illustrate 18:04

lambd0x yes yes ...
psch a $buf is a per-"character" (FSDO) representation of a string
R[DaneelOlivaw] I get trash when I view that file with `less`
psch: what's "D" in FSDO?
psch definition
because "character", "grapheme" and whatelsehaveyou 18:05

stanrifkin_ what means the "nom" in moar-nom or moar-blead-nom? 20:16
hoelzro stanrifkin_: nom is the name of Rakudo's default branch 20:17
[Coke] it meant: "new object model" 20:22
AlexDaniel by the way, why not call it “master”?
[Coke] now it's just nom. hasn't been new in many years
AlexDaniel: because we never switched it back. historical reasons. 20:23
master is just the default default, so ours is nom. there was talk of changing it, but the inertia is real.
hoelzro if it bugs you... git symbolic-ref master nom
disclaimer - I have no idea how badly that may break things like fetching and pushing >:) 20:24

harmil Pretty sure nom came from the pugs repo days. 20:38
Now I can't find a reference to that, and I'm doubting myself.... 20:39
El_Che I am working on a Solaris perl5 package. It would be fun if I could make one for perl6. But no luck with libuv :( 20:40
timotimo no, "nom" isn't that old
nom was when what is now known as "sixmodel" appeared, it's the "New Object Model" 20:41
hoelzro judging from git, nom is at least 5 years old
jnthn I *think* it was probably around 2010 or 2011
hoelzro 0998d86
2011-02-12
jnthn It may well have been me who made the branch :)
20:42 sufrostico left
hoelzro I think it was you jnthn: 317ff57 20:42
hoelzro kind of wishes dalek would throw in links for commit hashes
jnthn nom was a huge architectural overhaul; Rakudo's present architecture is a pretty direct descendent of what was introduced then. 20:43
20:43 sufrostico joined
timotimo that's a testament to how good the architecture is, or how stubborn & boneheaded we are :) 20:44
jnthn In changing so much, it also caused a lot of upheavel (and a lot of whining, because darn humans :P). And so master was left as the "original" Rakudo.
Eventually it became rather clear that yes, nom decidedly was the way forward, and the master branch was deleted...leaving nom. 20:45
And because git really doesn't care, and everyone was used to this, it stayed that way :) 20:46

AlexDaniel I know that rocks are going to fly into my direction after I say this, but given that it serves no useful information *today*, there's no reason to keep something that only makes people ask questions like “wtf is nom?” 20:49
timotimo "come to rakudo, we have nom!" 20:50
hoelzro wasn't there talk last year or so about renaming nom to master
?
stanrifkin_ AlexDaniel: right :)
[Coke] yes, there was talk about it.
nine Yes. We came close to gaining momentum for a rename after the GLR but I guess the travels surrounding SPW and YAPC killed it off again.
20:51 kid51 left
[Coke] AlexDaniel: given that github lets you pick a default other than master, it's not really stopping anyone from using the repo 20:51
And I'll write this convo today up into a wiki entry.
jnthn I'm quite curious how many folks have scripts that depend on the name nom. I've no idea if, for example, rakudobrew does :)
nine Nowadays I sometimes git checkout nom on projects where it's actually master ;) 20:52
AlexDaniel jnthn: what a nice opportunity to find out!
jnthn But yeah, I don't *think* anyone was strongly against it, it's just that nearly everyone has more useful things to be doing. :)
Uh, *had. 20:54
Last year, during the time of the GLR work and just about everything else. :)
hoelzro I think the rename is the easy part
jnthn The muscle memory is the hard part? :)
hoelzro not breaking scripts and getting every dev to switch to working on master is a bit harder =)
20:54 cpage_ left
AlexDaniel [Coke]: … actually, I think that instead of documenting old warts it is better to work on removing them… 20:55
jnthn Yeah, it'll have a non-zero cost :)
otoh, people asking about it every few months does too, so :P
20:55 sufrostico joined 20:57 skids left
hoelzro we could start transitioning by having the core devs add some push refspecs that made master a mirror of nom 20:59
20:59 holyghost joined
hoelzro and then, once that's working, remove nom on GH and see what happens 21:00
