vrurg I wonder if there is a way to make zef install only deps but skip their tests? zef install --deps-only --/test actually doesn't install test dependencies of the module too resutling in later test failure. 00:24

samebchase- Hello, I am looking for something like: zvon.org/other/haskell/Outputprelud...ate_f.html 07:43
So that I can do: take 10 (iterate (2*) 1) 07:44
which would give me:
[1,2,4,8,16,32,64,128,256,512]

moritz it seems .succ is the default for sequences anyway
samebchase- beautiful
I did realise I could do Date.new(2020, 3, 12) ... Date.new(2020, 3, 20), but I was having difficulty with the end range. The whatever star solves this elegantly. 07:48
oh and what's the difference between three dots (...) and two dots (..) 07:50
moritz m: say (1..3).^name 07:53
camelia Range
07:53 sena_kun joined
moritz two dots generate a Range, which has fast-path membership tests and the likes, but always assumes ascending order 07:53
three dots generate a sequence / lazy list / iterator thingy, with potentially any generator function 07:54
samebchase- ahhhh nice. That's what I needed.

m_v_m Hi all. I am just wondering...why tail of a one element array is equal to 'first' of the one element array?. In most know (to me) languages invoking 'tail' on [1] would return [] not 1. 13:45
lizmat tail gives the last element of a list 13:46
13:46 upupbb-user3 left
lizmat on a one element list, .head, .first and .tail give the same element 13:47
m_v_m this is strange :) In most know for me languages list could be pattern matched to [H | T] where H is the first element and T is the 'rest'. If there is a one element list then T would be nil or [] 13:48
moritz it seems Raku isn't most languages 13:49
m_v_m I see. Is there any reason behind it?

[Coke] yah, tail isn't cdr 13:56
13:56 guifa joined
[Coke] Something we could add to the docs if we have a xxxx-to-raku section for one of those languages. 13:59
moritz m_v_m: the functional languages approach is not a very intuitive interpretation of "tail"
m_v_m "not very intuitive" can you elaborate on that? 14:00
moritz ask a 5 year old where the tail of a queue of people is
and then ask them to point the 5 people at the tail of the queue 14:01
that's what an intuitive understanding of tail(5) is, IMHO
tail implies looking towards the end -- why it would count from the start, then?
14:02 caterfxo left
m_v_m In my opinion not :) specially in moments when first and tail are returning the same thing. 14:02
moritz well, but you asked for my elaboration
m_v_m true. Can I use something else which give me the same behaviour as a 'functional tail' without loosing performance? 14:03
Raku is a very flexible language so probably there is a short solution for my problem :) 14:04

m_v_m I have one more question. Do you know any real world usage of Raku? I mean companies :) I am just wondering. 14:17
moritz I know that nine's company has some services written in Raku 14:18
jnthn does work stuff with raku as well
jnthn My $dayjob has built multiple running-in-production things in Raku 14:19
Well, or has built them for customers
Implying that said people also use them. :)

m_v_m Wow! I thought that most of the cases would be around DSLs or something similar. So, most of the use cases are around devops, and Cro web framework? 14:31
lizmat m: dd <a b c d e f g>.skip # another way to get all elements except the first m_v_m moritz 14:32

[Coke] You have a very small sample size here. :)
and folks that also hack on the language are going to be an odd subset of users. :)
14:32 hoelzro joined 14:35 m_v_m left 14:37 MasterDuke joined
lizmat I guess adding a .cdr method as an alias for .skip would make people like m_v_m very happy 14:39
14:44 [Sno] joined
jnthn Perhaps also misleading in so far as the underlying representation is very different 14:45
14:51 devmikey joined
lizmat would that matter ? 14:56
isn't that an implementation detail ?
moritz LISP people kinda expect cdr to be O(1)
timotimo lists being immutable also allows sharing of pieces easily 14:57
but yeah, O(n) for cdr would be quite a surprise 14:58
14:58 rindolf joined
timotimo if you literally port a piece of lisp code, it'll be using car and cdr liberally, i'd imagine, and the performance characteristics could be far worse? 14:58
moritz yes 14:59

guifa just realized a great common use for phasers when he realized he could have used them in JS 15:28
guifa hates JS lol 15:29
when you do a for (foo of bar) loop, you can’t intercolate anything between loops 15:30
it’s either every loop or add in a conditional
but in Raku, NEXT { intercolated code }  15:31
