raydiak sure, what kind of details? 07:44

raydiak I deleted ~/.rakudobrew/moar-nom and started it recompiling before I thought to mention the problem here, so I can let you know in a couple minutes when it's done if it's still broken :) 07:51
nine It may have sufficed to just run panda's bootstrap.pl ;) 07:52
El_Che I noticed precomp generating false warning when developing a module (when the source is changed): gist.github.com/nxadm/1726865fe240719ae7d7
07:53 silug left
raydiak nine: already tried that, didn't help 07:53
El_Che even when you don't delete .precomp, the first run of the program (when not in a row) gives the warning: Use of uninitialized value %ENV of type Any in string context
nine El_Che: can you get the exact location of that message with --ll-exception? 07:54
El_Che ok
nine: identical output
it doesn't look like an exception, the program runs fine 07:55
07:57 hartenfels left
El_Che it's weird. If I run it in a series, only the first runs has it. If I wait a few minutes, the first time after that gives the warning. 07:57
ow, it's certainly related to 'run'
my $proc = run ~$.bin, ~$.file_left, ~$.file_right, :out; my $diff = $proc.out.slurp-rest; 07:58
commenting the run line out makes the warning disappear 07:59
nine El_Che: do you access %*ENV anywhere before that? 08:01
raydiak nine++ : that seems to have fixed it, I guess it was just something to do with recent changes and trying to rakudobrew over a rather old version...thanks for the help though :) 08:02

RabidGravy I asked thiis a long time ago, but I forgot the answer, how do I find whether a system is 32 or 64 bits (in a program) 09:16
I thought it was $?BITS but no
m: say $?BITS
camelia rakudo-moar 73d193: OUTPUT«5===SORRY!5=== Error while compiling /tmp/AoHnQIqjDE␤Variable '$?BITS' is not declared␤at /tmp/AoHnQIqjDE:1␤------> 3say 7⏏5$?BITS␤»

RabidGravy Oh yeah I'm looking at the code for that right here ;-) But I thought it was exposed somewhere 09:21
El_Che sorry nine, I was doing an intervention. Db is aan indexing now :)

RabidGravy strangely though

RabidGravy so how does that code in Int even work?
nine Maybe it's just allowed in the setting 09:24
lizmat only core settings are allowed to do $?FOO
at least until 6.c
RabidGravy ah okay
lizmat fwiw, the implementation of bits is now: $!bits //= $.hardware ~~ m/_64|w|amd64/ ?? 64 !! 32;
perhaps nine's code would be better ? 09:25
nine lizmat: it's not mine :) I found it in Int.pm
lizmat interesting
RabidGravy it's used for calculating the Range of an Int 09:26
nine Also those are answers to different questions: $*KERNEL.bits tells you if the operating system is 64 or 32 bits while $?BITS tells you what your rakudo supports. You could run a 32 Bit rakudo on a 64 Bit OS 09:27
lizmat hmmm... I vaguely remember some discussion about whether or not to expose $?BITS
RabidGravy m: use nqp; my constant MyInt = do { my int $a = 0x1ffffffff; nqp::iseq_i($a,8589934591) ?? int64 !! int32; }; say MyInt 09:28
camelia rakudo-moar 73d193: OUTPUT«(int64)␤»
RabidGravy that's sorta kinda what I want
lizmat RabidGravy: isn't that just "int" ? 09:29
RabidGravy is it? that would be lovely
nine int should be the platform int IIRC 09:30
lizmat afaik, "int" is defined as the platform int
hmm....
m: say int.Range

lizmat would be different on a 32bit build
RabidGravy I'm sure I had difficulty with it in a native binding before, but I'll try it and see 09:31

cuonglm Hi, anyone get error when installing rakudo from source with the latest git? 09:34
I got this error pastebin.com/3DiUSMn5 09:35
It seems that `tools/build/install-core-dist.pl` did not looking up the right destination dir
nine cuonglm: please remove your install/share/perl6 directory and run make install again. It's a one time issue caused by a change of versioning of the CORE dist 09:37

cuonglm :nine I used stow to manage /usr/local 09:40

brrt good hi #perl6 09:42
yoleaux 21 Dec 2015 15:02Z <RabidGravy> brrt: fixed LibraryCheck with v0.0.5
brrt RabidGravy++
are LPW2015 videos online yet
cuonglm :nine It's GNU stow
:nine Anyway, it worked now, remove my /usr/local/stow/perl6/share then make install again 09:43
:nine So every time version in CORE dist changed, I must do this action? 09:44
nine cuonglm: no, this one time only. We didn't change just the version but the way the version gets generated. Unfortunatly the new versions are lower than the old ones.

uruwi Strangely, on 64-bit platforms int is 64-bit on Linux but 32-bit on Windows 10:02
Or maybe it's because I was testing it on 2015.09 for Windows
dalek blets: 2854610 | lichtkind++ | docs/appendix-b-grouped.txt:
fix whitespace
nine uruwi: there are different models for what int should be on a 64 bit system. And I seem to remember that this is indeed a difference between Linux and Windows 10:03
uruwi m: my int $a = 2**63-1; ++$a; say $a;

brrt yes, windows is evil
nine uruwi: en.wikipedia.org/wiki/64-bit 10:04
uruwi That works on one line, but if I type each line individually on the REPL, the second line chokes the program
moritz uruwi: natives in the REPL are a known problem
RabidGravy uruwi, nine that's fine, what I'm doing is unlikey to work on windows anyway :) 10:07

yoleaux gfldex: I'll pass your message to timotimo.
timotimo gfldex: sure
yoleaux 02:05Z <gfldex> timotimo: the monkeyness of EVAL was weekly forgotten
10:38Z <gfldex> timotimo: please ignore me, i'm visually challenged
_nadim Can someone please remind me (again) how I can return a reference? sub my_sub { my %h ; .... ; return %h, 42} (%h,$i) = my_sub ; 10:39
timotimo i just woke up for this
nine _nadim: &my_sub
_nadim nine: thanks, and the explanation for this ugliness is?
10:42 M-eternaleye joined
_nadim well that actually makes no difference! 10:43
gfldex _nadim: you can return anything but a reference
there may be reasons to return an explicit capture in some cases tho 10:44
_nadim that's what I thought but I get odd number of elements, 2 secs
llfourn m: sub my_sub { return { a => 'b'}, 42 }; my (%h,$i) := my_sub(); %h.say; $i.say #crosses fingers 10:45

FROGGS the %h will gobble the stuff
m: sub my_sub {my %h = a => 1 ; %h, 42} ; my ($h, $i) = my_sub();
camelia ( no output )
FROGGS m: sub my_sub {my %h = a => 1 ; %h, 42} ; my ($h, $i) = my_sub(); say $h
camelia rakudo-moar 73d193: OUTPUT«a => 1␤»
FROGGS _nadim ^^ 10:48
timotimo maybe we should warn when we see something like (%h, $i) = ... ?
_nadim anything that doesn't force me to change sigil?
nine timotimo: and (@a, $i) = ...
llfourn _nadim: the reason it errored in your last example was because you didn't use :=
timotimo yeah
_nadim Argggg! 10:49
and I knew that
gfldex a slurpy has to be at the end of a parameter list
timotimo well, it's not really a slurpy
FROGGS m: sub my_sub {my %h = a => 1 ; %h, 42} ; my (%h, $i) := my_sub(); say %h
camelia rakudo-moar 73d193: OUTPUT«a => 1␤»
timotimo slurpyness only works on signature binding
FROGGS so yeah, we should warn and hint at these two options 10:50
timotimo in this case it's just regular assignment that breaks things
_nadim I was a bit proud that I finally used := for something yesterday and now it bites me back
gfldex binding is hard
10:52 cibs joined, M-Illandan joined
timotimo when trying to wake up i had the excellent idea for a toy language named "SnoozePL" 10:53
you get a barrage of random statements and all you can do is snooze them or execute them
so it's more like a interactive programming experience
gfldex is that the language electronic sheep deam in? 10:54
uruwi Hmm, even having a terminal-like character grid in the browser poses a big problem.]
timotimo i wouldn't recommend dreaming in that language
uruwi: hum? 10:55
uruwi all fun and games until you want to display Japanese
(was going to use unicodetiles.js for frontend)
10:55 crux left
uruwi at least it works in dom mode 10:57
timotimo i have kind of no clue what you're talking about 10:58
uruwi Now I'm considering a still text-based, but having stuff like tables interface
TEttinger uruwi: rot.js ?
uruwi I planned on a text-based RPG
timotimo text-based RPG: easy. text-based JRPG: really difficult! 10:59
uruwi TEttinger: I looked at it, but I just need a way to display things as most of the work will be in Perl 6
10:59 cibs left
TEttinger ah ok 10:59
timotimo: sounds like Tinder: the PL 11:01
swipe left or right
uruwi at least this works imgur.com/x11ALpc, but I'm worried about how much space English text will take then 11:02
11:02 rindolf joined
timotimo hehe 11:02
"what kind of statement do you like?"
uruwi (as I also plan on supporting multiple languages)
timotimo you're using double-width ascii? 11:03
actually, compared between the japanese and english characters it looks like the ascii is quad-width
11:04 cibs joined
uruwi Well, it's not supposed to be double-width; that's just how it looks once you put fullwidth characters in DOM mode 11:05
in WebGL or canvas display, half the character gets cut off.
Plus all the space between the lines; I'm afraid that UT won't work. 11:06

lizmat we should probably warn on creating a sub with the name of a class in scope 11:07
uruwi At least not for anything outside a map interface, so the HTTP protocol will be more complex.
lizmat m: { class A { } }; sub A { say "foo" }; A # and class being our by default, makes things more complicated
