Kaiepi timitimo i ran it for 10 seconds and it ended up with 871.7MB of allocations 00:24
00:27 zacts left
Kaiepi the panic doesn't seem to be happening anymore though 00:28
timotimo 871 memory in usage at that point, or 871 mb cumulative allocations? 00:31
Kaiepi cumulative 00:32
timotimo that's not terribly surprising, i think 00:34
Kaiepi i'll check how much was unmapped over that time
00:36 burgulus joined 00:39 MasterDuke joined 00:40 MasterDuke left, MasterDuke joined
Kaiepi 525.6MB deallocated cumulative 00:41
so i have no idea what was happening earlier
burgulus is there a way to initialize a variable that was declared in a role, from the constructor of the class that does that role? 01:00
role a { has $.t } class b does a { $.t=1 } 01:05
01:07 aborazmeh left
lookatme_q m: role foo { has $.t; submethod BUILD() { $!t = $!t // 1 } }; class bar does foo { }; say bar.new 01:07
camelia bar.new(t => 1)
MasterDuke m: role A { has $.a }; class B does A { }; my $b = B.new(a => "ab"); say $b.a 01:08
camelia ab
lookatme_q oh, I misunderstand :/
m: role foo { has $.t; }; class bar does foo { }; say bar.new(:t6) 01:09
camelia bar.new(t => Any)
lookatme_q m: role foo { has $.t; }; class bar does foo { }; say bar.new(t => 6)
camelia bar.new(t => 6)
burgulus it is possible in my case the consumer of the class doesn't have the information, which would allow to pass in t 01:15
is there a constructor overload that would also allow the normal new to be called? Seems when I override new, the object is only a type object at the time of variable access. 01:16
class a { has $.t; }; class b is a { method new() { $.t = 1; }}; my $i = b.new; 01:18
Cannot look up attributes in a b type object.
lookatme_q burgulus, docs.perl6.org/language/objects#in...8method%29 01:19
I recommend you read the documents first
burgulus thanks I will read this section. I've been on the documents for a couple hrs now, but didn't know where to be directed. 01:20

ufobat ive got a sub that has a couplse of say's in it, as well as a run(), and i just see all the says after the run() returned. what could cause this delayed printing on the console? 11:00
AlexDaniel ufobat: stdout vs stderr? 11:01
ufobat all on stdout
lizmat buffering ?
jnthn Is it direct to the terminal, or is there something between it?
ufobat well not true, the run prints on stderr, maybe, if i dont specify anything
i invoke the perl process directly on my git shell (on windows) 11:02
jnthn If the output isn't to a TTY then it will turn on output buffering
ufobat how do i figure out if my terminal as a tty?
jnthn $*OUT.t I guess 11:03
cpan-p6 New module released to CPAN! Crypt-CAST5 (0.1.0) by 03KAIEPI
jnthn You can see what $*OUT.out-buffer says to see if it's turned on
ufobat docker -ti --rm alpine complains that there is no tty. so i am not having a TTY
can i disable buffering? 11:04
timotimo i'd expect setting $*OUT.out-buffer to 0 or False would do that, but haven't tried 11:05
ufobat $*OUT.out-buffer is set to 0
El_Che ufobat: an alpine bug? I remember something about it. 11:06
ufobat El_Che, no the docker was just my way to checfk whether there is a tty or not
i am on windows right now :(
El_Che ah ok 11:07
ufobat $*OUT.t is False, and $*OUT.out-buffer is 0 :-(
jnthn Try $*OUT.out-buffer = False
ufobat aha! works 11:08
thanks to everyone! 11:09
jnthn wonders if we could do anything better, but if the thing really isn't claiming to be a TTY to other programs, it's not a bug in our "is this a TTY" detection 11:10

ufobat i dont have enough windows know how to comment on that topic, but if (most, cmd and powershell) do not claim to have a TTY then this is not the information to rely on for enabling buffering or not 11:43

but it's still a nice gesture
sjn aw
tyil I have infra to host more bots, but idk if freenode will be happy if I have 10 bots coming from my IP all of a sudden :p
sjn likes karma bots
lizmat tyil: maybe only say "New" if it is an initial update of the module ? 14:17
tyil lizmat: that can be done soon-ish
I dont have any database with old module info yet
but I have the database to store this ready, I just need to import some data into it
and the program to import data into it should also be mostly usable

so store it somewhere, don't let it explode in sink context 19:15
melezhik Hi moritz: let me show a certain example 19:16
m: 'run "fff", :out'
camelia WARNINGS for <tmp>:
Useless use of constant string "run \"fff\", :out" in sink context (line 1)
melezhik m: run "fff", :out
camelia The spawned command 'fff' exited unsuccessfully (exit code: 1)
in block <unit> at <tmp> line 1
timotimo m: my $run-val = run "fff", :out; say $run-val.^name; say $run-val.exitcode; say "alive" 19:17
camelia Proc
1
alive
melezhik I'd like to avoid exceptions, through "run" parameters, is it possible?
timotimo like this -^
melezhik ahh, should I assign?
timotimo "disarm" the Proc object that is returned by Proc
that's what moritz told you :)
melezhik moritz: thanks! 19:18
timotimo: thanks too ((=:
but I also need to get stdout IF command is successful 19:19
normally this is achievable by
sorry, 5 secs 19:20

melezhik well look like I die when I try to close 19:22

camelia ()

melezhik that the case
how can I handle that?
timotimo the return value of $a.out.close is what's blowing up 19:24
m: my $a = run "lggggg", :out; say $a.out.lines; $a.out.close().^name
camelia ()
timotimo m: my $a = run "lggggg", :out; say $a.out.lines; say $a.out.close().^name

timotimo it's the Proc object "again", and it has the exit code in it as well

timotimo also thanks, AlexDaniel :) 19:28

melezhik timotimo: so it's just an .^name at the end to do the trick? 19:37
19:39 ravenousmoose left
melezhik anyway, it works. thank you! 19:41
timotimo well, not really 19:43
just don't sink the value itself
store it away and it'll be fine

Kaiepi didn't this used to work? 19:50
timotimo i would expect it to, yeah
19:52 melezhik left
Kaiepi what does "is raw" do? 19:59
timotimo defers selection of context (item vs list for example) but doesn't require a writable container like "is rw" does

tyil lizmat: I now have the database up-and-running to keep track of modules, so I can also implement new vs updated module text 20:44
not sure if I want to do that first, or make a program to crawl the entire cpan index for perl 6 modules 20:45
to ensure the database is complete
does anyone know if cpan has ratelimiting on http requests? or can I just fire at it as fast as computerly possible? 20:46
timotimo have you looked at how exactly modules.perl6.org uses rsync with cpan? 20:54
tyil not yet 20:55
timotimo only for CPAN/authors/id?
it does finish really quickly
modules.perl6.org/update.log - just looking at the log right now
tyil I was looking at ecogen, which is used to generate info for zef
if im correct
timotimo ah, i think that's right
tyil where can I find the code behind the update mechanism for modules.perl6.org? 20:57
timotimo i think it's the same name on github under perl6/
tyil found it github.com/perl6/modules.perl6.org
20:58 Praise- joined, Praise- left, Praise- joined
tyil it doesnt look like perl 6 tho ;~; 20:58
timotimo the web app definitely isn't 20:59
not sure about the updater script
tyil github.com/perl6/modules.perl6.org...ct-list.pl
its perl 5
but I can gather the required info from it nonetheless I think

leont is rather surprised to discover modules.perl6.org is written in perl5 23:37
sena_kun well... 23:48
I suspect it was written when Perl 6 was not as mature as it is now, ecosystem-wise, performance-wise. Attempts to rewrite it in Perl 6 are welcome, one can suspect. :) 23:50
