k-man how can i test if a string does not contain any letters? 00:34
when not ($msg ~~ /\w/) {return "Whatever."} doesn't seem to be doing what I want 00:40
Grinnz \w is word characters, which is a lot more than letters
k-man ah 00:42
leont Also, you probably want to use !~~
k-man ok good tip 00:43
when ($msg !~~ /<alpha>/) {return "Whatever."} 00:44
that seeems to work I think
00:45 sena_kun left 00:48 Actualey` left
rypervenche What is the best way to remove an element from an array (of hashes)? I saw something that Liz wrote that was essentially doing: @array .= grep: *<foo> ne $bar; Is there a better or more specific way to do this? 00:52
wildtrees so I do : my $p = Promise.start(&routine) ; it starts running routine as a promise, how do I kill or break the promise from outside? yells at me about it already being vowed 00:57
leont You can't 01:00
01:01 sena_kun joined
wildtrees would I need to use something other than a promise if I wanted to kill the "process/thread" from outside? 01:04
leont You could wrap it in another Promise if you really want to though
You can't kill the thread/task from the outside, AFAIK
This is generally a surprisingly difficult thing in threads, not just in raku
(just imagine killing a thread that holds a lock for an idea of the kind of thing that can go wrong) 01:05
wildtrees so I would need to pass in a channel or a supply into the Promise that could signal a kill message, and have the promise check the channe/supply for a death notice?

elcaro if you just want ascii letters, you can be explicit, ie: /<[A .. Z] + [a .. z]>/ 01:57
01:58 Kaiepi joined, wildtrees left
elcaro or if you want to match anything Unicode says is a letter, then use /<:Letter>/ or just /<:L>/ 01:58

rypervenche Oh...
Ok, new question. Is there a shorthand for: @array = @array[1..10] ? 03:38
03:46 mahmudov left
guifa2 You mean starting at 1? 03:52
There isn't, but you could make on

I forgot ^^ was an infix already ^_^ 03:54

evalable6 [1 2 3 4]
guifa2 rypervenche: see above 03:56
rypervenche I meant with any range, although I could make one with an infix using your above examples. Thanks. 03:58
guifa2 Oh, you were referring to the $range returning the value of 4 (range = listy = numeric context is the number of elements) 04:02
If you were out of scalar context, it would work differently
my @array = ^100; my @range = 2..5; @array[@range].say 04:03
evalable6 (2 3 4 5)
guifa2 If you really want to keep the range in a scalar
my @array = ^100; my $range = 2..5; @array[$range.list].say
evalable6 (2 3 4 5)
guifa2 my @array = ^100; my $range = 2..5; @array[$range.list].say; @array[$range<>].say; @array[|$range].say 04:04
evalable6 (2 3 4 5)
(2 3 4 5)
(2 3 4 5)
guifa2 three different ways you can do it from a scalar :-)
rypervenche Oh, don't know why I didn't just make it an array then. Good to know. And this is good practice with | 04:19
Oh, wouldn't be lazy then. 04:20
I think I'll stop there for tonight. As always, thanks for the help. 04:21

abraxxa I let the grammar only parse the variable definition and added a private hash to the action class which fills it and uses it 09:28
AlexDaniel`: I'd move async and grammars up as they are the major distinctions from other languages 09:29
'every' can do OO

El_Che CIAvash: are you planning to add a light mode? 10:14
AlexDaniel` El_Che my understanding is that CIAvash won't be able to work on improvements, so we need a maintainer first in order to have plans :) 10:16
Light/dark is easy to do nowadays with pure css 10:17

10:21 hungrydonkey left
abraxxa a json repsonse returns a hash containing a 'data' key that contains a list 10:21
when i return that from a method and assign it to an array it has only a single element which in turn is an array 10:22
why does this happen?
I find myself always having to call .list or .slip in such cases

El_Che abraxxa: it makes sense to me 10:31
abraxxa: you don't want to flatten data by default
jnthn Hash values are items, and return retains the itemness
10:31 hungrydonkey joined
abraxxa I just don't get the rules to understand what to do when 10:33
does Raku also return different types based on the caller like Perl 5? 10:34
scalar vs list context?
sub foo { my @ary; return @ary; } my @main-ary = foo; 10:35
and now @main-ary doesn't contain the same as @ary, that's just weird
as they are the same type
docs.raku.org/type/Array doesn't even document the list method 10:37
El_Che I don't think raku has a return list context 10:40
(but I could be wrong)
docs.raku.org/type/Signature#Retur...row:_--%3E suggest an item return 10:41
10:42 Doc_Holliwood joined 10:45 hungrydonkey left
abraxxa ok, but still requires the .list method call 10:47

tbrowder but i see a possible advantage in using local raku modules by installing them with zef 16:24

only this module 16:26
rypervenche abraxxa: It's still an issue: github.com/Raku/doc/issues/2896

melezhik abraxxa: github.com/vrurg/raku-IP-Addr/issues/5
16:26 hythm joined
abraxxa melezhik: that's the module I'm trying to install ;) 16:27
melezhik this is issue with p6doc itself
not with the IP::Addr 16:28
abraxxa I don't see a workaround in those two issues
can I do anything when not having root access? 16:30
is p6doc something deprecated or wasn't it just not renamed to rakudoc? 16:31
tbrowder any suggestions about the best way to install local modules? special location or namespace? 16:34
[Coke] it hasn't been renamed. 16:35
It also has had install problems for a bit.
abraxxa is it an optional dependency I can skip?
guifa I find the easiest way is to just cd into the module’s directory (where the META6.json) is and ‘zef install .’ 16:37
[Coke] Who is depending on it? 16:38
I wouldn't expect a generic module to depend on it. 16:39
rypervenche It would be nice to be able to use it from one's home directory installation.
abraxxa ===> Searching for missing dependencies: JSON::Name, JSON::Tiny
===> Building: p6doc:ver<1.003>:auth<perl6>
one of those two
is there maybe an additional debian package I can install that provides it? 16:40
IP::Addr itself: modules.raku.org/dist/IP::Addr:cpa...META6.json 16:41
16:42 dakkar left, dakkar joined
[Coke] both of those have empty depends, I think 16:43
(modules.raku.org/dist/JSON::Tiny:c...META6.json , modules.raku.org/dist/JSON::Name:c...ETA6.json)
What were you installing? 16:44
abraxxa melezhik: can you get rid of the p6doc dependency?
[Coke] the "missing dep.." is showing things missing, not the original install
abraxxa [Coke]: see above, already wrote that its IP::Addr itself
[Coke] ah. it's got a "build-depends". 16:45
abraxxa yes
should the rakudo-pkg debian package not include p6doc?
[Coke] Not if it's going to fail. :)
I don't see anything in IP::Addr that requires p6doc. 16:46
It's listed as a dep, but there's no Build.pm...
guessing it was a boilerplate that snuck in 16:47
tbrowder looking at zef's README, it suggest's using PERL6LIB along with "-to=" for a non-default install location which looks like a good solution to my needs. 16:48
16:49 Doc_Holliwood left, Doc_Holliwood joined
[Coke] looks like build-depends was removed in master on git 16:49
so you can probably zef install <git url> but then you're getting a non-release version, maybe, not an official cpan release. 16:50

abraxxa I used the --force-build the zef output suggested on fail which worked 16:59
melezhik tbrowder: "looking at zef's README, it suggest's using PERL6LIB along with "-to=" - I am afraid this does not solve the issue 17:00
abraxxa: `zef --force-build install p6doc && zef install IP::Addr` 17:01
abraxxa melezhik: zef --force-build IP::Addr worked as well, thanks 17:03
i have this wonderful line: my @destinations = @rules.grep({ .<dst> }).map({ .<dst>.Slip }).unique(:with(&[eqv]));
rypervenche abraxxa: It will install, but it won't actually work.
abraxxa .<dst> happens to be an array sometimes I want to flatten but neither .flat before .unique nor .flat before the .Slip helps
rypervenche If you want to use p6doc, that is. 17:04
abraxxa rypervenche: IP::Addr works
that's what I care about
[Coke] note that force build just gets you past the install failure. it doesn't actually give you a working p6doc. 17:10
abraxxa i don't need one!
[Coke] (rather, none of the docs get installed that way, so you can run p6doc, but then it never finds anything) 17:11
the right thing is to remove the dep on it, hopefully we can get another release of that module that removes it.

melezhik with RakuDist you jave probable the most minimalistic setup for TravisCI - github.com/melezhik/RakuDist/blob/...on-example
to test Raku module hosted in github, just `curl repo.westus.cloudapp.azure.com/raku...r/$project -s | bash`
SmokeMachine jnthn: do you think `method bla(--> self)` would make sense? would that be possible to implement? 20:14
melezhik for example - `curl repo.westus.cloudapp.azure.com/raku.../sparrowdo -s | bash`

[Coke] (p6doc) it's not trying *on purpose* to install into system directories, it's an attempt to compensate for docs being in "doc/" instead of "lib/" in the repo 20:31

[Coke] .ask nine - can you take a look at github.com/Raku/doc/blob/master/Build.pm6#L9 ? It's trying to install stuff from doc as if it were in lib/, but is accidentally installing to the system repo and not whatever the default target install dir is (so installing as a non-priv'd user fails) 20:32

vinay Hello, I am Vinay Vyas. I am new to this org. Can someone please direct me to the getting started page.
[Coke] raku.org? 20:34
Let us know if you're looking for some
20:34 lucasb left
[Coke] thing in particular 20:34
vinay I was looking for perl foundation, trying to get started for gsoc 2020 for the same org 20:35
[Coke] ok. Raku, GSOC and TPF are three different things, but we're definitely the right spot for anything gsoc Raku related. 20:37
I think jmerelo was our GSOC leader, but he's on european time.
How far along is GSOC this year? Are you applying? chosen? 20:39
Sorry, I'm out of the loop. 20:40
vinay Can you direct me to the getting start page where i can get get the required installation guides and contribution procedures.
[Coke] I don't know anything about your particular project or if Merelo has put together a page. But if you want to have a copy of Raku so you can start working: 20:41
raku.org/ - Download
vinay the orgs who would be selected is not released yet. Its due date is 21 feb.
[Coke] That's generic. Anyone know if there's anything GSOC specific?
vinay: ah, thanks. Thanks for showing up early! 20:42
depending on the nature of what you end up working on, you may want the source build; the rakudo star build is closer to "batteries included", but may be a little behind. 20:43
Folks here are happy to help if you have any install or build issues. What OS are you on, out of curiousity?
vinay I use ubuntu, but i am fine with windows as well. I thing ubuntu would be preferred 20:44
[Coke] If you're comfortable doing development work on windows, it's fine, but ubuntu's probably easier all around. 20:46

vinay github.com/perl Is this the main git page for perl. Or raku, i am not sure? 20:53
sena_kun vinay: github.com/raku/ is the organization for Raku 20:55
perl is for perl. :)
[Coke] TPF is probably covering for both Raku & Perl in GSOC 20:56
vinay What exactly is raku. I found this on a page for The Perl Foundation 20:57
[Coke] Sorry for the historical confusion.
Raku is a new language.
Historically, it was called "Perl 6".
Currently, it's called Raku, and TPF is the foundation for both Raku & Perl. 20:58
vinay Okay, thanks for clarifying.
[Coke] It's definitely Perl-ish.
vinay So what github page do we use for Raku? 20:59
[Coke] the org is at /Raku 21:00
the compiler is at /Rakudo/rakudo
er, /rakudo/rakudo
(separate orgs because we have commiter license agreements for the compiler only)
and also we try to maintain the separation between language spec & compiler
rakudo is technically "a" compiler, as opposed to "the" compiler. (it's also basically the only one right now, though.) 21:01

chloekek $num == $num.Int 21:30
That checks for integers by the way. To check for natural numbers you also have to check that it is not negative, e.g. $num == $num.Int && $num >= 0 21:31
Or >= 1 if you’re one of those people.
