cono hi all, does any1 know why slurp definition dissapeared from Configure.pl ? Undefined subroutine &main::slurp called at Configure.pl line 48. 10:08
timotimo huh, a version or features pragma got lost? 10:10
oh, you may have to re-run Configure.pl in moar, nqp, rakudo, and perhaps do some aggressive submodule updating or something?!
10:12 domidumont left
cono previously I was needed just do Configure.pl --gen-moar --gen-nqp --backends=moar --make-install 10:12
now it fails for me, if I put sub slurp { local $/; ...} it works 10:13
10:13 xiaoyafeng left
timotimo "git submodule status"? 10:16

10:18 gabiruh left, reach_satori joined
timotimo that means it's checked out and at the right revision, right? 10:19
yes, indeed
cono yup
timotimo odd. why does it b0rk on your machine but not in CI? 10:20
oh, also, slurp isn't behind "use feature", it's an actual module, isn't it 10:21
cono dunno, I usually write it by my own, for 3 lines of code, no need to use module :D 10:22
I'm building rakudo on 3 different machines, and on all 3 its broken :(
2 linux boxes and 1 mac
timotimo perhaps it's just --gen-moar or --gen-nqp that's broken and nobody else uses it?!
cono could be 10:23
timotimo lib/NQP/Config/Rakudo.pm
9:use NQP::Config qw<slurp read_config cmp_rev system_or_die run_or_die>;
cono where is this lib/NQP ? 10:24
timotimo that module has slurp in its @EXPORT_OK, but i don't see a "use" corresponding to slurp
that's in build/ i think
and the one with the EXPORT_OK in it is in 3rdparty-nqp-configure/lib/NQP/Config.pm
cono grep "NQP::Config " Configure.pl : use NQP::Config qw<system_or_die>; 10:26
NQP::Config qw<system_or_die slurp>;
fixes the problem
10:28 reach_satori left
timotimo it looks like slurp is only used when a config.default exists? 10:28
cono yeah 10:29
timotimo i don't seem to have that
cono `/usr/bin/perl Configure.pl "--gen-moar" "--backends=moar" "--make-install" $*`
pretty usable
timotimo oh, you put that in there and then just running Configure.pl without arguments uses what's in there? 10:30
cono yup 10:31

AlexDaniel :) 12:00
wanderer_ Not sure I can copy-paste here.
AlexDaniel if it's not a single line of code it's better to use gist.github.com/

masak wanderer_: `is tighter(&infix:<*>)` -- that's still pretty loose for a prefix :) 12:19

masak for example, `!2 ** 3` would mean `!(2 ** 3)` 12:20
against, I think, most people's expectations
aside from that, it looks good, IMO :) 12:21
wanderer_ Thanks!
masak not sure why your prefix:<!> doesn't conflict with the built-in one... 12:22
wanderer_ Are there any published benchmarks for the MoarVM in comparison to some other JIT compiler?
As in benchmarksgame-team.pages.debian.n...-fast.html 12:23
I thought it might. I’m going by intuition. That is literally my first ever script.
cono its getting better every week. I follow it all the time and running my sandbox programs, and really like the progress1 12:26
12:27 john_parr left
wanderer_ masak_: Is it because I must declare the argument type and return type for prefix:<!>? 12:29
Would you also recommend `is tighter(&postfix:<**>`? 12:30
Or `is tighter(&infix:<**>)` or whatever... 12:33
masak I wouldn't anchor it in an infix at all; I'd probably `is equiv(&prefix:<?>)` or some such 12:34
the (tight) prefixes are all on the same precedence level, and that's likely the one you want to be on 12:35
cpan-p6 New module released to CPAN! Term::Form (1.2.4) by 03KUERBIS 12:36

wanderer_ I think some of you should contribute Perl 6 programs to _The Computer Language Benchmarks Game_. The language should deserves a spot here: benchmarksgame-team.pages.debian.n...-fast.html 13:52

timotimo if the game wants the fastest version of an algo written in each language, it'd be fine to write programs with lots of nqp:: ops to get more speed but also a program that looks like nothing any regular perl6 user would prite 13:55

lembark Q: Is there any way to write a test to prefer ./lib without having to set PERL6LIB prior to executing the tests? 16:13
use lib requires a hard-coded value, which doesn't always work. 16:14
moritz what's wrong with "use lib 'lib';"? 16:15
it makes assumptions about the working directory, but I think that's workable
lembark e.g., ./t/x/y/01-frobnicate.t.
moritz you can use non-constant expressions with use lib, as long as they can be evaluated at compile time 16:16
lembark Rather use FindBin at which point I can use Bin.

Question is how to add an entry to $*Repo in BEGIN block. 16:17
I may also have multiple dir's above the current one w/in a project. Would like to find things there without having to hard-code and update them every time a new part of the project is added.
is there nothing anywhere which can manage $*REPO? 16:18

timotimo lizmat: if you just don't bind anything, then that's rather strange semantics for STOREing into arrays that already have some values in them 16:19
lizmat timotimo: good point :-) 16:20
timotimo lembark: "use lib" is how you manage REPO, i think?
lizmat then we can use nqp::ifnull, we just need to tell the generator somehow what the "empty" value is
timotimo right
can the "is default" also be code that runs to generate value, or just plain values that get cloned? 16:21
lizmat plain values, at least in the current situation
if you make the default a Callable, then that Callable is what you'll get
16:21 cpan-p6 left
lizmat which may be useful for the default case in dispatch tables, specifically when based on hashes 16:22

timotimo right 16:22
moritz lembark: I've looked through github.com/moritz/perl6-all-modules/ for mentions of $*REPO, and most only read it. github/ugexe/Perl6-CompUnit--Repository--Github and github/zostay/p6-CompUnit-DynamicLib might be more interesting to you 16:23
lizmat tries to remember the name of the load balancing algorithm that jnthn had in mind for hyper
timotimo round robin? exponential back-off? TCP slow-start? %) 16:24
none of these make too much sense
moritz winner-takes-it-all 16:25

i wonder if we should try to re-use the batcher and combiner from HyperSeq for feeds
lembark Checking it now, thank you.
timotimo lembark: you can always "constant thing-to-use = do { #`( this code runs at compile time, because of the ‘constant’ keyword ) }; use lib thing-to-use 16:26
lizmat timotimo: re-use of something we want to re-imagine, does not look very useful 16:27
timotimo my thoughts are that the difference between hyper and feed are in the stages in between, not the beginning and end 16:28
for hyper, you batch the input up and feed them to multiple workers; each worker does the desired work from start to finish and submits to the combiner
for feed, you batch the input up and feed it to the first worker, which does the first bit of work. then the first worker passes the batch to the second worker, and at the end the combiner puts them back together 16:29
lizmat gist.github.com/lizmat/8652e4a403f...2b31cc6ad4 is an implementation of a parallel feed operator
timotimo: ^^

sena_kun lizmat, how to run makeNATIVE_ARRAY correctly? 17:12
lizmat perl6 tools/build/makeNATIVE_ARRAY.p6 <src/core/native_array >new && mv new src/core/native_array.pm6 17:15
oops
perl6 tools/build/makeNATIVE_ARRAY.p6 <src/core/native_array.pm6 >new && mv new src/core/native_array.pm6
sena_kun also, there is a thing I don't understand... 17:16
moritz quantum field theory? :D
sena_kun in the code that throws we are using Array(my @foo; @foo[1] = 5;), but the suggested place for a patch is for List candidate... So I was wondering about this one. 17:17
moritz, yup,this one too.
17:18 |oLa| left
lizmat sena_kun: hmmm... maybe we don't need the @values candidate then ? 17:19
worth a try :-)

lucs Sure, mais encore? (pardon my French, but it's really the best question :-) 17:32
Lets say: tell me more.
Is it just a place to poke those bots more privately than here? 17:33
17:33 vrurg left
sena_kun lucs, yes, to not spam this channel with a lot of queries 17:34
lucs Makes sense, thanks.
sena_kun lucs, it isn't too "private" as it is a public channel, but if you don't want to disturb anyone, that's the rigt channel
*right 17:35
lucs Welp, turns out my bisection turned up no problem, yet I do have a problem here (perhaps due to my 32-bit system here -- will attempt to bisect here). 17:37
timotimo it's also the channel for whateverable development
like, debugging versions of the bots will go there, but not in the other perl6 channels
17:38 coldforged joined
coldforged hello everybody.. 17:38
i just joined to check up on perl6
sena_kun coldforged, o/
17:38 nadim joined
coldforged and am wondering if there's a stable version i can use in production? 17:38
of freebsd 11 servers 17:39
/of/on/
timotimo aye, you can run the rakudo star releases, they are stable
coldforged oh great! been wanting to get started on it. been using perl since the 90's for alsorts of things, including web apps 17:40
as i understand it, 6 is something different from the previous versions 17:41
is it in the freebsd ports tree already? 17:43
timotimo i'm not sure about bsd, but we have someone working on bsd stuff
Kaypie: can you help? 17:44
coldforged oh i see it is! :) lang/rakudo
timotimo cool 17:45
coldforged then it's just a question if it's the current one
bsd ports are always behind a little
Kaypie i'm pretty sure it's in ports but it's an old version 17:46
17:46 Kaypie is now known as Kaiepi
coldforged so i'd have to get a release and compile it myself 17:46
Kaiepi on openbsd and netbsd they're at least a year old, which is before 6.d 17:47
yes
coldforged these ones will do? rakudoport.sourceforge.net/
17:48 feldspath joined
coldforged ah wait. that's the ports again. 17:48
is there a page that will tell me what to install if i go with source? as i see it, there's a couple of things i will have to compile and install 17:49
like parrot, rakudo.. 17:50
moritz parrot is dead
sena_kun parrot is no longer a thing for a while. there is an instruction at perl6.org/downloads/ <- see "installing from sources"
moritz as a rule of thumb, everthing about perl 6 that mentions parrot is sufficiently out of date to best be ignored 17:51
coldforged maybe if i understand it all better, i can make a port (or at least a tgz file) for it
moritz the build order is MoarVM -> nqp -> rakudo
coldforged so, don't bother with parrot and only go for rakudo
17:52 natrys joined
moritz and if you download rakudo from source, and run perl Makefile.pl --gen-moar, it'll download and build MoarVM and NQP for you 17:52
coldforged that's perl.. 5? (the makefile) ;)
i will go and try on a virgin freebsd vm, and see what happend! 17:53
happens..
moritz yes
coldforged thanks for the info! :)
moritz fwiw perl5 is only used at build time 17:54
coldforged i guess that's the case up to the point that perl6 is installed by default in the OS 17:55
at the moment, it's 5 allover
maybe push the fbsd guys a bit and move to 6!
i take it, not all modules of 5 are available in 6.. but is there a thing like cpan up and running for 6 already? 17:57
sena_kun coldforged, 1)Perl 6 modules can be uploaded on CPAN; 2)there is a github-based ecosystem too that is slightly easier to use, but that's preference; 3)currently most popular package manager works with both; 17:58
timotimo coldforged: if you use a --prefix that's system-wide, please be advised that --gen-moar will build *and install* moar and then nqp, which will fail if you don't have write access. yes, we are aware that doing "make install" during a Configure.pl is bad, but we haven't been able to make it much better yet. 18:01

nadim Evening everyone, I am a bit curious about what a Rakudo::Internals::LoweredAwayLexical is (found in a CallFrame.$.my) as well as ForeignCode (found in a Backtrace) 18:38
18:38 sena_kun left 18:39 sena_kun joined, molaf left
timotimo nadim: the "LoweredAwayLexical" is when a lexical value was decided to not need a full lexical because no inner scopes were accessing it 18:40
nadim ahhhh!
timotimo by the optimizer
nadim timotimo: why differentiate between a lexical that's used in the current scope and one that is not used in inner scopes? 18:46
timotimo locals are a whole lot cheaper 18:47
every frame has one piece of memory for locals ando ne piece of memory for lexicals
when a frame is left, the locals can be thrown away, but lexicals have to be kept around for things like closures
nadim OK 18:48
timotimo and the dynamic optimizer knows more about handling locals compared to lexicals 18:51
nadim and ForeignCode? that poped up in a BackTrace::Frame->$.code->$!do and gotmy dumper in a loop trying to dump it.
Not that I think people are going to use DDT to dump BackTraces ;) 18:52
timotimo i think ForeignCode is more or less just an object you can barely do anything at all with, except maybe invoke it 18:55

i generally just have a --prefix that points into my home directory, in my case ~/perl6/install 19:25
