Zoffix Don't know much about it, but looks like it's a problem in rakudo. A race conditon somewhere or something.

jmerelo El_Che: yep, it's not working...
Or maybe it took too long docs.perl6.org/build-log/build-201...+00:00.log 07:28
Anyway, I don't see it updating the modules... 07:29
El_Che jmerelo: i will probably move a repo to de perl6 org. Do you have any idea if/how travis and dockerhub automation work? is that part still linked to your account on those services or it uses a perl6 org account?
07:31 parv joined
jmerelo It's linked to any account with write privileges in the repo, I think. 07:31
07:32 sena_kun left
jmerelo You will notified of errors occurring with your pushes, you'll still see all repos in which you have write premission. I see all perl6/ repos in Travis. 07:32
El_Che true
travis is straightfw 07:33
d
but dockerhub does not had a direct link for automated builds
07:33 dakkar joined
jmerelo You can just say which repo you will use, right? 07:37
El_Che yes, but it will create an img on your personal repo 07:40
that's a fairly ok scenario. I wonder what happens when you need encryption keys, even encrypted 07:41
travis encrypt them for you personal username
07:41 scimon joined
El_Che will those secret be decryptable? Can those be echoes (the probably are)? 07:42
jmerelo El_Che: it does not work with PRs, and probably not with other usernames.
El_Che: no, it does not echo by default encrypted variables and no variable can be used in PRs. They've got that pretty much covered. 07:43
El_Che the canary repo I am working on does need travis and dockerhub integration (it's linked to my username), but no extra keys needed
that would be different if you need to upload stuff to bintray
jmerelo: are you sure? your app need the unencrypted value 07:44
write the value to a file, put it in the package and you have the secret
(it's a shared repo, after all)
jmerelo El_Che: no problem if you're doing it yourself. yes problem in PRs or if someone else does it. 07:45
El_Che yes, that's the issue
jmerelo El_Che: then you're probably better off keeping it in your own private repo. It can still be used from perl6 repos, I guess. 07:46

jkramer lizmat: Who are ports like P5chdir aimed for, when P6 has chdir builtin already? Are there people who'd actually rather use a module like that than changing their code to use IO.chdir? 12:23
BTW I went through the top dependencies list from yesterday and a huge lot of the most-used modules are kinda obselete in P6 anyway, since they're builtin/available in the standard library - which is pretty awesome for P6 I think :) 12:25
I think I might try to implement Term::ReadKey in P6 since its there seems to be demand for it and playing with term controls might be interesting as it probably requires native stuff 12:28

El_Che what is the stance of small applications in the ecosystem? In Go there are zillions of lib in github that are a go get away. Do we want growth through quantity of a more select approach? 12:33
I asked becasue I wrote a small app yesterday that looks for newer version of software and nudge (by email, rest of whatever) the user 12:34
should that kind of stuff live in github or be part of the ecosystem (it's a generic Module + cmd line app that uses it) 12:35

luffysenpai I'm supposed to be learning simple perl scripts to be implemented via cmd tomorrow in an exam, and thse links you've provided already help a bunch!
Juerd luffysenpai: Note that if it's homework, it might be about Perl 5 instead of Perl 6
Zoffix luffysenpai: uh.. are you sure the exam is about Perl 6 and not Perl (as in Perl 5)? They're different languages; like C vs C++ 13:28
luffysenpai I'm looking forward to learning, at what point doI begin to contribue though?
It's about perl 5 but I'm interested in perl 6, so this is extra-curricular for me
Zoffix luffysenpai: you can contribute right away. A lot of people start off with the docs, since as a newcomer it's a lot easier for you to see what needs to be improved. There's also a bunch of open Issues: github.com/perl6/doc/issues 13:29
luffysenpai I'm already making comparisons between 5 and 6

comborico1611 I'm trying to figure out what this simple example is doing: hastebin.com/bituxeyuza.pl 13:55
Zoffix comborico1611: it fails to compile because variable is not defined :P
comborico1611 Yeah, I don't think it is runable. But the author is trying to teach something from it, but I don't get it. 13:56
Zoffix comborico1611: but basically @array is a thing that holds a bunch of things and each of the things it holds is numbered (called an index) and you can store or retrieve those things by using @array[$index]. And for cases when you want to store/retrieve more than one thing at the same time, there's "array slice" syntax, where you give more than one index at the same time, e.g. @array[0, 2];. In that example, the 13:57
more than one index is stored in another array @keys. And then you assign more than one thing by doing @array[@keys] = @lettters; So the first item in @letters will go to index 0 and second item in @letters will go to index 2

Zoffix is a Unicode n00b
timotimo we don't yet have a "just decode this unicode" mode, we always do normalization at the moment

jmerelo mcmillhj: you can also try StackOverflow... 15:29
jkramer It basically reads the input as single bytes and appends them to a buffer. As soon as Buf.decode works without an exception, it returns that as result
mcmillhj jmerelo: I can post it there if you all want to have some sort of record of the question, I just couldn't see from the docs how to apply a signature to multiple parameters across several functions 15:30

Zoffix has no idea where they are documented... 15:32
mcmillhj oh interesting, so that is a new type instead of a signature applied to multiple parameters
it's possible I was thinking of the problem incorrectly and that is why it wasn't in the docs
Zoffix mcmillhj: pretty much
mcmillhj I was looking here: docs.perl6.org/type/Signature 15:33
Zoffix You can't instantiate it or anything, but you can typecheck against it
jmerelo mcmillhj: you can check out this article by Zoffix perl6advent.wordpress.com/2016/12/...6-subsets/ 15:34
Zoffix mcmillhj: found a bit of docs here: docs.perl6.org/language/typesystem#subset
jmerelo mcmillhj: but yep, that would be an excellent question for StackOverflow. 15:35
Zoffix gulps at that article
mcmillhj I'll ask it there as well so there is a record and include both answers
jmerelo Zoffix: subsets are not in the index, though...
Zoffix Maybe it's because of the indexing issue tho. or was that fixed/
mcmillhj I was specifically thinking about sharing this somehow: my $sig = :(Int $a where $a >= 2 && $a <= 62);
not sure if that is possible
jmerelo Zoffix: we haven't even figured it out.
chansen_ jkramer: Hopefully this will be rectified, there are three levels of layers in Unicode: code units, code points and logical characters. 15:36
15:36 wamba left
jmerelo mcmillhj: you can't declare signatures and then use them for declaring routines, unfortunately 15:36
Zoffix mcmillhj: share how? Isn't that what subset would do? You're constraining by Int and a custom codeblock in both cases
mcmillhj jmerelo: okay, that is where I got lost then :) 15:37

I've installed readline with zef and it seems I was succesfull. If there is a place where I could read me through what is the url? Google did not have a clue

jmerelo ced_: Can you also post that question in StackOverflow? To gather more answers and/or give it more visibility. Thanks! 15:49

This IRC channel and Twitter are amazing for getting your questions answered knowledgeably, amiably and fast. 15:59
However, it's not the best thing for indexing those questions and answers. Somebody looking for perl6-debug-m is highly unlikely to arrive to the 300th line in an IRC day log.

Zoffix comborico1611: the string is *printed* by the routine. The routine returns the argument you give it. And that argument defaults to Any type object if you don't give it an argument (which is the case in both the first and second calls) 17:03
s/same as the rest/same as the second/;
colomon as given the code doesn’t do anything with the return value of the function
I added “say” to each of the last three lines so I’d know what it was doing. 17:04
Zoffix m: sub z ($arg?) { $arg }; dd z; dd z(); dd z 42; 17:05
camelia Any $arg = Any
Any $arg = Any
Int $arg = 42
Zoffix comborico1611: ^ a bit clearer example that actually dumps the return value
comborico1611 colomon: Yes, the "say" trick helps. I'm not sure what this all means, but I get the string + Any etc
Zoffix m: sub z ($arg = Int) { $arg }; say z; say z(); say z 42;
camelia (Int)
(Int)
42
colomon comborico1611: no, the function call PRINTS the string (that’s what say does) and then returns $arg. 17:06
Zoffix ^ and here a different default was given, so that's what's returned when no args are given
17:06 Zoffix left
comborico1611 Alright. I think I'm back on track now. 17:09
Thanks!
colomon it would have been clearer to use dd (like Zoffix++ did back there a few lines) instead of say for the results of the calls to with-optional, at it would help visually distinguish what is being printed by say in the function from what is returned. 17:15

mcmillhj How do I indicate that I want an Array of Arrays? I notice that this appears to get flattened `my @queue = (('a', 'b'));` however if start with two elements no flattening occurs: `my @queue = (('a', 'b'), ('c', 'd'));` 18:21

mcmillhj I can't seem to figure out what this means: `Type check failed in binding to parameter '@seq'; expected Positional[Array] but got Array ($[1, 8])` 19:11
I have a subroutine that accepts an Array: `sub search(Array @seq where *.elems == 2) { ... }` and I am pretty sure I am passing an Array to it via `search([1, 8]);` 19:12
AlexDaniel mcmillhj: well, @seq by itself will take an array just fine 19:13

mcmillhj Is it possible to use an Array as a key in a Hash? I read through this section in the docs: docs.perl6.org/type/Hash#Non-strin...ject_hash) which sort of implies this would work. I can't get it to work when trying however: gist.github.com/mcmillhj/e2200a93f...e811b20cac 19:53
tobs mcmillhj: looks like it's slicing the hash instead. I don't know if you can tell it not to. 19:59

Zoffix .tell mcmillhj You can use Arrays for hash keys, but it's likely to be pain, since they're not value types (so you'd have to use the same Array object to do the lookup, not one that just has the same values). Also, you need to place it into a Scalar container to tell the compiler you want to treat it as one item (the key) instead of a list of keys. Lastly, by default hashes stringigfy keys, so you'll need to
yoleaux Zoffix: I'll pass your message to mcmillhj.

Kaiepi does perl6 have an event loop? 20:59
moritz rakudo uses moarvm, and moarvm uses libuv, which has an event loop 21:01

jnthn Kaiepi: MoarVM runs an event loop internally using libuv, but that's very much implementation detail. 22:20

Kaiepi ah 22:21
so it's not the same type of dela as node's
jnthn No. By design. :-) 22:22
Everything is exposed in terms of Promise (single async value) and Supply (stream of async values). 22:23
