azawawi: thanks
azawawi thx
AlexDaniel azawawi: what is $o in in $o.cleanup example? 03:13
in README.md
was it meant to be $wand ?
azawawi think of it as a handle to an image 03:14
or multiple images
because you could for example add multiple images and then create an animated gif 03:15
or an AVI or MP4 movie via ffmpeg
it is really a powerful api 03:16
03:16 ely-se left
AlexDaniel azawawi: I'm not sure if I'm folliwing it. Should the example actually show something that does not compile? 03:17
or perhaps consider adding a comment like # $o is a handle to some image 03:18
azawawi sure i will update it
i will add a user guide after finishing 02-effects.pl6 03:19

AlexDaniel: help is welcome :) 03:24
AlexDaniel: i started this project like 10 days ago
AlexDaniel azawawi: yeah, I see. Well, earlier I was doing that kind of stuff through 「run」 and command line tools, so… as soon as I rewrite my code you'll possibly see some bug reports. But that takes time :) 03:26

Hotkeys is there a hash type in which order matters?
MadcapJake AlexDaniel: yeah I can, I'll need to make a bot for that too, so I was thinking making a server app that does both
plus current evalbot is written in Perl 5 :) 03:33

danzulla i used to learn perl5 with chatbots, years ago. i loved it.
MadcapJake it might be slow, but won't know unless i try xD
AlexDaniel danzulla: by “actually working” you mean? 03:38
danzulla i got rakudo and some CPAN stuff that claimed to implement perl6. it never seemed to be "official"
AlexDaniel danzulla: because to me it was “actually working” for a few years now
danzulla but i might have been just a stupid slave to perl online marketing
MadcapJake danzulla: have you used panda yet? 03:39
danzulla nope
what's panda?
MadcapJake oh then you are definitely out of date
panda is the current defacto module installer for rakudo
rakudobrew is the easiest method atm to install a full working suite of moarvm,nqp,rakudo,panda,Task::Star (that last one is a collection of useful modules to get you started) 03:40
danzulla did you guys write anything meaningful in perl6? i'd love to take a look.

03:41 Sgeo_ joined
Juerd danzulla: Yes, I write several kinds of one-off scripts in Perl 6 now. Mostly just to figure out how everything works. 03:41
danzulla: Eventually I expect to use Perl 6 in production, and I want to get to know the language well before that :) 03:42
One issue for me is that we tend to run high traffic web stuff on small and cheap virtual servers, and Perl 6 is still rather memory hungry and slowish. But it's improving. 03:43
danzulla It'd be interesting to see some Perl6 job offerings.
03:43 Sgeo left
Juerd A simple script taking 300 MB of memory is a problem for me, given that most of the "machines" I work with, have 512 MB of RAM :) 03:44
danzulla @Juerd: Is Perl6 JIT or is there an Ahead of Time compiler as in Google Go already?
Or is somebody working on it?
That's what I really like about Go. 03:45
Juerd danzulla: I'm not familiar with the details but I believe Perl 6 has a JIT.
AlexDaniel it has JIT, but a bunch of optimizations are done without JIT :) 03:46
danzulla @Juerd: Seems like you have some experience with Perl6 on VMs. Which is useful.
Juerd danzulla: Not really, I've only used Perl 6 on my own computer so far
AlexDaniel danzulla: that being said, some things are relatively slow right now. 2016 is supposed to be a big year for Perl 6 speed 03:47
danzulla: earlier efforts were focused on other things
e.g. getting things to work correctly
Juerd Or getting things to work at all :)

Hotkeys oh 04:53
how do I do a hash of anythings
skids Do you really care that it is a Hash, or will any Associative do?
Hotkeys multi yaml2qtree (Hash %h) { ... } is what the declaration looks like 04:54
I assumed it meant it took a hash
skids just :(%h) will take any Associative, which is probably good enough.
Hotkeys ah
geekosaur % already means hash (or at leasr Associative)
Hotkeys okay
great thanks, all is working now 04:56

Skarsnik When changing somehting in src/core/ I have to make again? 12:24
FROGGS Skarsnik: just 'make install' 12:25
no configure needed, unless you add files to src/, which also means you need to add stuff to the Makefile.in files for moar and jvm 12:26
Skarsnik I am changing how Usage display stuff for main. Like put the slurpy at the end instead of before the positionnal 12:27
FROGGS yeah, just make install 12:28
Skarsnik because foo --a --b [...slurpy] hello bar
make no sense

Skarsnik Also I want to change the order of display for the arguments help. it use a hash so it's displayed in a 'random' order. should I sort like by alphebetic order or keep the order in MAIN signature? 12:32
12:32 perlawhirl joined
moritz either makes sense 12:32
and either is better than random ordering 12:33
Skarsnik I should look at the spec x)
perlawhirl El_Che: it's not much consolation for proc that exit without sending anything to stderr... but for ones that do, you catch :err and check for output, ie: run('proc', :out, :err); if $proc.err.lines { ... } 12:35
12:35 st_iron joined
perlawhirl thats how i've worked around it. 12:35
st_iron hi
Skarsnik whelp there is nothing x)
gfldex m: say "Hi st_iron!" 12:39
camelia rakudo-moar a5fe34: OUTPUT«Hi st_iron!␤»
Skarsnik ah interesting Pod error? sub MAIN( $hello #= the hello arg the doc get attached to MAIN and not hello 12:40
st_iron m: say "Greetings!"
camelia rakudo-moar a5fe34: OUTPUT«Greetings!␤»
jnthn Skarsnik: What if you put the , after $hello ? 12:41
jnthn vaguely recalls the attachment code being in the actino run when parameter is reduced, but we won't have considered the parameter full parsed at that point.. 12:42
Skarsnik sub MAIN( $hello, #= the hello arg do the same 12:43
If I put on the next line it work
it just surprised me x) 12:44
Usage: testmain.p6 [--all] [--define-enum=<Str>] <header-file> [<gccoptions> ...] Ok that definitly better at least 12:45
jnthn Skarsnik: Yeah. It may be fixable by moving the attachment logic to param_var. hoelzro is probably the person "in the know" about this :) 12:48
12:51 kjs_ left
Skarsnik hm, how I can keep a hash (or some an eqv) that keep an ordered based on insertion? 12:52
and my english is aweful today 12:55
12:55 kjs_ joined 12:58 cognominal joined
st_iron maybe a stupid idea, but you can put keys in an array 13:00
that's ordered
Skarsnik Yes, actually I can maybe use a array of Pair
13:02 juu joined
Skarsnik m: my @tab; for ^10 {my $k = ("a".."z").pick; @tab.push($k => $_); say $k }; for @tab -> $v { say $v.key, $v.value} 13:06

hoelzro_ Skarsnik: hmm...interesting bug; I'm surprised roast didn't catch that 13:24
jnthn is right; attaching docs to params is a bit odd
