raschipi Which range wouldn't work? 00:20
timotimo <foo bar baz quux>
raschipi Oh, I see
timotimo though tbh i didn't read the original question 00:21
raschipi If you want steps instead of multiples, starting with the first, be it even or odd, and adding a step each time.
That range should wield 1 3 5 7 9 11 13 15 17 19 00:22

jaush Greetings! I'm encountered a problem whilst attempting first-ever zef install: 02:03
kurahaupo skids: do you mean wrong for failing to warn about the duplicate :a ?
jaush "zef install --/test cro" on Windows, with Rakudo Star version 2018.04.1 built on MoarVM version 2018.04.1 02:04
Enabled fetching backends [path pswebrequest] don't understand git://github.com/jnthn/p6-docker-file.git You may need to configure one of the following backends, or install its underlying software - [git curl wget]
kurahaupo Obviously only one value can go in a named scalar parameter
jaush i understand how to go about fixing this (dependency whack-a-mole), but it seems that the module manager should *just work* 02:05

yy6p6 hi 04:02
how can I generate an executable for a file?
I want a jar
I use 04:03
./perl6-j --target=jar --output="hello.jar" hello.p6
in hello.p6 i have
sub MAIN(){ say "hi"; }
evalable6 hi
benjikun I see a thread in which he uses `perl6 --target=jvm --output=name.jar name.p6` 04:05
yy6p6 java -jar hello.jar >>>>> no main manifest attribute, in hello.jar
benjikun you probably have to add a manifest file manually then 04:07
04:07 entonian left
yy6p6 @benjikun if I use --target=jvm I get null pointer exception; here github.com/rakudo/rakudo/blob/nom/...unning.pod it says that jar is an option 04:07
I think I did not write that MAIN sub as it should be 04:08
but I am not sure
benjikun Oops, jar is the correct option 04:09
Apparently you can't run the jar that's created with any typical JVM
According to this thread, there's some script that hasn't been implemented in rakudo to do this yet 04:11
yy6p6 I used rakudo
benjikun github.com/perl6/nqp/blob/standalo...-script.sh
yy6p6 isn't thare compiler that can do this? :( 04:12

recommend pinging bartolin if you have any questions, he's doing the most work on it right now 04:14
yy6p6 bartolin: is there any way to create a jar? 04:19
MasterDuke yy6p6: fyi, i don't know exactly what timezone he's in, but he isn't usually active around now 04:22
you can use the .tell command to leave him messages

13:25 mahafyi joined
timotimo hm, if you have rakudo star 2018-04, surely your zef is new enough to understand that directive? 13:27
what's the zef version? i think you get it from "zef info zef"
bazzaar timotimo: Identity: zef:ver<0.4.2>, ... Installed: Yes, as zef:ver<0.3.1> 13:30
timotimo hm, maybe update that?
i have zef:ver<0.2.2> there and <0.4.2> available, but "zef install zef" doesn't think it should upgrade? hm. 13:31
ok, now it's up to date on my end, too 13:32

El_Che install a local zef? zef --install-to=home install zef 13:40
and make sure ~/.perl6/bin is before the paths for star 13:41

Clarifying list and item assignment.

This would close #1810. I have opted for deleting a single example and clarifying it by explaining it together with another example, and clarifying also what assignments we refer to in every line. It's a little less dense-ish, but my impression is that if there were better documentation supporting list and item context, this could probably go easily by just saying that list assignment occurs in list context, item assignment in item context. That documentation is not there yet, but when it's there, we might want to come back here to rewrite it completely.		 17:03

slayergames How does 1, 1, * + * ... * (Fibonacci sequence) work? Is it the ... operator? 18:27
18:28 espadrine_ left
jmerelo slayergames: that, and everything else. … is a "generator", that makes the * + * lazily generate the sequence. 18:29
slayergames is * a shortcut for a function? 18:30
jmerelo slayergames: * is called "Whatever"
slayergames: it's variable, actually, or rather a "slot". It might be a bit confusing here, since the two * mean a different thing, but maybe see this 18:31

jmerelo slayergames: so first * is actually the first argument of the generating expression, which I call here $^a, second * is $^b, third * means "All elements of this sequence", and can be substituted by Inf (or Infinity) 18:32
slayergames: ^30 is for the first 30 elements, as you might have seen.

jmerelo slayergames: another way of writing the same: as an anonymous subroutine, which is what it is... (that's also in the documentation)
raschipi The first two splats make an anonymous subroutine, and the … sequence operator knows to feed it the last two values of the sequence. It also knows that when it gets a plat on the other side it means "keep going". 18:36

what is .&[**]?
timotimo ... is just super awesome in general
slayergames is .& some kind of map?
timotimo &[**] is syntactic sugar for &infix:<**>, i.e. the "real name" of the ** operator
slayergames oh 19:34
timotimo and foo.&bleh(bar) is syntax for &bleh(foo, bar)
well, bleh(foo, bar) really
since the & is not necessary when you're calling a sub
Zoffix slayergames: &[**] is short for &infix:<**> which is a noun form of the `2 ** 2` verb. The `.` is the method call. So you're using the operator as a method, giving the invocant as the first arg and in the eval above there's also the second arg: the power to raise the invocant into
slayergames i discovered perl 6 last week, it's really intuitive
Zoffix slayergames: and » is a hyper metaop, it hypers that method call over elements of that range, similar to how a map would work 19:35
slayergames is there a tk library for perl 6? 19:36
Zoffix (^20)».&[**]: 2 => (^20)».&[**](2) => (^20).map(* ** 2) => (0..19).map(* ** 2) # this is just equivalent for this case. hyper metaop has extra features like descending into iterables and autothreadin g
timotimo we don't have tk directly in perl6, but you can get a tk via Inline::Python or Inline::Perl5, or you can use GTK instead of TK
