TEttinger camelia doesn't show up on perl6.org? 08:14
jmerelo TEttinger: It's coming. In an evil way.
TEttinger it's also easter, so, second coming 08:15
jmerelo TEttinger: :-)
moritz: that was an ephemeral prank... 08:16
TEttinger yeah, gone now
jmerelo Oh, no! The evil bug has infected the documentation too! docs.perl6.org/ 08:19
Zoffix Today's Easter Sunday and you guys are giving Camelia beastly horns? Fairly inappropriate, especially for a language with terminology influenced by Christianity. 08:21
jmerelo Zoffix: they are actually Viking horns.
TEttinger april fools, it's very appropriate!
jmerelo Come to think of the Viking thing, I should have changed the name to þerl 08:22
TEttinger is that thorn?
wynn would also work 08:23

Zoffix jmerelo: and 666?
TEttinger ᚹERL6
jmerelo TEttinger: way cool
Zoffix: it's the third year of Perl 6, so it's like three sixes. 08:24
TEttinger Zoffix: you could change it to Perl 69 and make the whole page NSFW 08:25
araraloren 666 :)
jmerelo 69 is actually the Piscis sign
Zoffix jmerelo: but why deface the site with antagonistic symbols?
TEttinger are you not familiar with april fool's day? 08:26
jmerelo Zoffix: it's an April fools prank. It's a single commit. I can revert it if anyone is going to be offended.
TEttinger i hope zoffix is pranking 08:27
Zoffix TEttinger: I'm not familiar with using antichrist symbolisms on April Fools Day.
jmerelo Zoffix: we can link your repo github.com/zoffixznet/perl6-666 if you want 08:28
TEttinger Zoffix frantically googles to make sure Google's CADIE AI is just a prank 08:29
Guest524 is it possible to use any file extension for importing scripts? 08:31
Zoffix TEttinger: so is there a point where you clarify to me the association?
Guest524: improting to where?
Guest524 sub EXPORT {%('$var'=>'test',)} # abc.pm6 08:32
use lib '.'; use abc:file('abc.pm6'); say $var;
instead of abc.pm6 could it be abd.def?
Zoffix Guest524: no, it has to be .pm6 08:33
Guest524 there's no other way to do it? 08:34
Zoffix Guest524: no simple way, no. 08:35
Guest524 what about a complex way?
Zoffix Guest524: can the importing code change?
Guest524 do you mean by editing? 08:36
Zoffix Guest524: yeah, like does it have to remain as `use blah blah` or can it be something else?
jmerelo Evil camelia un-deployed 08:39
Guest524 Zoffix: app.p6 has a subroutine f() and needs to import app.cfg which wants to call that subroutine f()
jmerelo Will take a while to move to the page, though.
Zoffix Guest524: usually it's the other way around tho, you import a routine *from* a module and call it in app.p6. 08:41
Guest524: what task are you trying to do?
I mean, as a general thing, not as importing something from somewhere else.
Guest524 use perl in a configuration file 08:42
araraloren I think they don't care the format
Zoffix Guest524: ok, that's easy enough: my %conf = EVALFILE 'conf.p6'; where conf.p6 has Perl 6 generate a Hash that's the last line of the file (and thus is used as return value). 08:44
araraloren m: my $x = 10; 'say $x'.EVAL 08:45
camelia 10
Zoffix Guest524: does that solve your entire problem or do you still need to import something? 08:46
Guest524 Zoffix: glot.io/snippets/ezpgermp27 08:59
the website doesn't allow changing file names, but dio.pl6 should be app.cfg and main.pl6 should be app.p6
Zoffix Guest524: what happens if main.pl6 doesn't have `sub f` defined? 09:00
Guest524 err? 09:01
Zoffix Guest524: well, what's the connection between `sub f` and its use in the config file? Why does the config file need to call any function as opposed to just giving a List of elements and main.pl6 doing whatever it needs to do with them, like calling `f` with each element? 09:02
jmerelo: thanks. 09:03
Guest524 Zoffix: to use perl for confuration? 09:05
Geth_ doc: ceebae4781 | (JJ Merelo)++ | doc/Type/Capture.pod6
Adds indexing terms to capture literals

Closes #1443		 09:08
synopsebot Link: doc.perl6.org/type/Capture
Zoffix Guest524: you can use it without having to call `f` inside the configuration: gist.github.com/zoffixznet/e1c26e5...4ce1065b77 09:09
Guest524: inside abc.def I have a list of lists. It's the last statement of the file so it gets returned when I call EVALFILE 'abc.def'; and then I iterate over that list, calling `f` with each inner list. 09:10
Zoffix Guest524: and the list of lists is just a return data structure in this case; you're free to execute arbitrary Perl 6 code inside that file to, for example, generate that list of lists (or some other datastructure). Basically, the idea is to separate the configuration from what's done with it, and then you don't need to import `f` into anything. 09:14

Zoffix, gist.github.com/cad4c9e4791410c235...7ed839c608
Guest524 Zoffix: what is the pipe in `f |$_ for @confs;`? 09:17
Zoffix Guest524: it causes the argument to be "slipped". $_ contains a list of 3 things. If I just call `f $_` that's a call with single argument (the entire list); but writing as `f |$_` slips that list, and I end up making the call with 3 arguments (each element of the list became an argument on its own) 09:19
Unsure where that's documented. docs.perl6.org/routine/%7C mentions what happens, but very briefly and without any examples. 09:20
Guest524 Zoffix: how do you learn about this stuff? 09:21
Zoffix Guest524: just hanging around here and seeing code, I guess. Some stuff by reading the compiler's code. I started back when there were very limited docs, but I think right now it should be documented somewhere, I'm just unsure where exactly. 09:22
fatguy: looks like it's not the overriding but the missing attribute's value, no? There's an empty array printed. 09:23

fatguy: filed as github.com/rakudo/rakudo/issues/1679
fatguy zoffix: thanks ! 09:29
Zoffix fatguy: you could use this as a dirty workaround until the problem is fixed. Basically, manually calling BUILDALL of one of the ancestors so it sets the attribute's value: gist.github.com/zoffixznet/6bab930...p6-L16-L20 09:34
fatguy zoffix: alright thanks \o/ 09:37
Zoffix fatguy: oh wait, got a simpler one. Just add any attribute into the grafik-gabungan like `has $!dummy-until-rakudo-bug-is-fixed` 09:38

tobs Only half a question about perl6: I used to get OOM Killed sometime last year while downloading binary files using WWW::get. It only happened with certain files, presumably because get returns decoded-content(?). At some point I installed rakudo 2017.10 which now gives me its own "MoarVM panic: Memory allocation failed"s instead, but when I ran it a few times and used HTTP::UserAgent.get with :bin, it didn't 14:54
terminate but froze my computer. Had to do a hard reset after a minute of no reaction.
Can anyone tell me how to debug this safely, to find an offending file first of all? Would a ulimit -m be enough?
timotimo ulimit should definitely help 14:56

herby_ got a rookie question 16:44
I have a simple module I'm working on. I want the user to either be able to use it from the command line and pass in arguements, or use it from within their own script 16:45
I know I should use MAIN for command line use. is MAIN ignored if the script isn't used from the command line?
moritz it's supposed to be ignored if it's not in the top-level script 16:53
no idea how well that works
herby_ I think I'm missing a simple design step. If I have a module that has a "test" function, and a "MAIN" function, and I call the "test" function, it will return both functions automatically 16:55
rather, if I call the "test" function from within the module, it runs the "test" function and MAIN function
probably not explaining that clearly

masak herby_: not sure it directly fixes your problem, but I usually have a `multi MAIN("test") { ... }`, so that I can run tests easily from the command line

timotimo herby_: i think we generally have a launcher in bin/ and a module that exports a MAIN sub to it 17:02
github.com/ugexe/zef/blob/master/bin/zef - check this example 17:03
github.com/ugexe/zef/blob/master/l...ef/CLI.pm6 - this is the module in question
it's a package that has a bunch of multi MAIN ... is export { }
herby_ timotimo: thanks, i'll give that a read 17:05
benjikun What's the best way you guys can figure out how to generate a "look and say" sequence (1, 11, 21, 1211) 18:04
can you do it with a one-liner? 18:05
maybe with the ... operator thing
cfa benjikun: rosettacode.org/wiki/Look-and-say_...nce#Perl_6 18:12
masak oh, that's pretty
I started in on a solution, but mine was veering off in the wrong direction, trying to do everything in a single regex 18:14
benjikun cfa: that's a good one
cfa to be clear: not my solution 18:15
i'm just the link butler
benjikun yeah I understand
ty anyhow
cfa np
benjikun How would I output that to a file 18:25
benjikun I can't do $fh.say for ... 18:25
or spurt
jnthn $fh.say($_) for ... 18:26
benjikun oh 18:27
ty
herby_ If I want to validate if a supplied IPv4 address is valid or not, does p6 have anything built in? 18:49
a quick google shows that python can utilize the "socket" library, didn't know if p6 had something similar
El_Che herby_: docs.perl6.org/type/IO::Socket::INET (dunno if it soes what you want) 18:52
herby_ El_Che: thanks. I was poking around there but I couldn't see anything that explicity talks about it, and my socket/networking knowledge is pretty much zero 18:54
I'll do some more reading :)
El_Che herby_: it sould be pretty easy to write a small ip validation function 18:55
herby_ yep, I found one in Think Perl 6 for IPv4. If there wasn't already an ip validator that was widely available, I was going to write a small module for it
timotimo just don't try to validate ipv6 addresses by yourself unless you know about the weirder parts of the spec :)
herby_ but I didnt want to clutter the ecosystem
timotimo: yeah, it looks like ipv6 is a tad more complex than ipv4 18:56
El_Che timotimo: doest sound that hard

benjikun How much slower is perl6 for these sorts of algorithms compared to C/C++
jmerelo It's actually faster than C++ for most things.
benjikun hm
