tbrowder what is advantage of using discord here? 12:45
ugexe many people are already in other discord channels, and possibly not in any other irc channels. so they don't need an irc client and can continue using the chat format (discord) they are used to for everything else 12:59
12:59 jpn joined 13:29 formiko joined, formiko left
librasteve discord is a trendy way for "half-geeks" to chat - but irc needs real geek skills to stop getting ejected every time you restart your machine (screen?), to see the messages you missed and to add images and multiline code snippets (irccloud app?) ... but you need to turn off all Discorrd animations to retain your sanity 14:02
antononcube @tbrowder "what is advantage of using discord here?" -- You can have direct conversations with @librasteve , @antononcube , and @Nemokosch . 14:42
@tbrowder More seriously, Discord is simply a more convenient way to communicate in every way than IRC. 14:46

Guest45 Hi all. I have an array of two-element lists. I want to append items from a separate 1-d array to each inner list, giving an array of three-element lists. Here's what I have so far: 15:18
$ raku
Welcome to Rakudo™ v2024.02.
Implementing the Raku® Programming Language v6.d.
Built on MoarVM version 2024.02.
To exit type 'exit' or '^D'
[0] > my @a = ((0,1),(2,3))
[(0 1) (2 3)]
[1] > my @b = (8,9)
[8 9]
[2] > @a Z @b
(((0 1) 8) ((2 3) 9))  ## Not quite. I want flat inner lists. 15:19
[3] > (@a Z @b).map: *.flat
(([0 1] 8) ([2 3] 9))  ## ??
[4] > (@a.List Z @b.List).map: *.flat
((0 1 8) (2 3 9))      ## ok, but whaa?
[5] >
So, a) What are the '.List's doing? And b) surely there's a better way. Any suggestions?
[Coke] For multi line pastes, please use something like gist.github.com instead for future ones.
librasteve or if you move over to Discord (on a non-bridged channel) then you can use triple backticks for code quoting 15:20
(btw I leanred this the hard way)
[Coke] Guest45 - the .List is converting from an Array to a List 15:22
m: my @a = ((0,1),(2,3)); dd @a.^name; dd @a.List.^name;
camelia "Array"
"List"
librasteve m: my @a = ((0,1),(2,3)); my @b = (8,9); say @a Z, @b; 15:29
evalable6 (((0 1) 8) ((2 3) 9))
Raku eval (((0 1) 8) ((2 3) 9))
librasteve this is the best way I know to do the first part - can't avoid doing map flat on the result afaik 15:30
[Coke] the , is implied if left off, I think
librasteve note the comma ',' does all the work 15:31
oh - ok ... I see that Geust45 had that part right in the first place ;-)
[Coke] Right, I think the question is, why does this not work:
m: my @a = ((0,1),(2,3)); my @b = (8,9); dd (@a Z @b).map(*.flat) 15:32
camelia (($(0, 1), 8).Seq, ($(2, 3), 9).Seq).Seq
[Coke] m: my @a = ((0,1),(2,3)); my @b = (8,9); dd (@a.List Z @b.List).map(*.flat) # but this does
camelia ((0, 1, 8).Seq, (2, 3, 9).Seq).Seq
[Coke] m: my @a = ((0,1),(2,3)); dd @a; dd @a.flat; dd @a.List; dd @a.List.flat; 15:33
camelia Mu @a = [(0, 1), (2, 3)]
($(0, 1), $(2, 3)).Seq
((0, 1), (2, 3))
(0, 1, 2, 3).Seq
[Coke] docs.raku.org/language/list#Itemization 15:34
"Second, remember that these invisible dollar signs also protect against flattening, so you cannot really flatten the elements inside of an Array with a normal call to flat or .flat.
Guest45: Hope that helps. 15:37
librasteve Array.raku does not put $ to explicitly show scalars, unlike List.raku:
15:43 jpn left 15:44 jpn joined
I kinda sympathize with the language design decision to preserve nesting structure of arrays and lists, that way I can make more sophisticated repeating patterns (I guess a 3D array would be an example of that), and I can be confident that I can pass it around without having some routine accidentally flatten it - but it sure is hard to get your head around 15:45
[Coke] m: my @a = ((0,1),(2,3)); say @a; say @a.raku; dd @a; 15:47
camelia [(0 1) (2 3)]
Mu @a = [(0, 1), (2, 3)]
[(0, 1), (2, 3)]
[Coke] (just checking that all the diagnostics there "hide" the $() ) 15:48

nahita3882 alternatives: list comprehension ((|.[0], .[1]) for @a Z @b) or with map @a.map({ |$_, @b[$++] }) 16:06
16:10 haxxelotto left
another because why not sub infix:<AP> { |@^a, $^b }; @a ZAP @b 16:12
ab5tract I like that ZAP solution quite a lot 16:21
nahita3882 (thanks, could have named more descriptively like { |@^sub-list, $^tail }) 16:27

xihitrchdg hell 18:17
roguerakudev Is there a certain order in which grammars will attempt to match proto candidates? I have some candidates which are basically subsets of others, e.g. an integer with a certain number of digits vs an integer with any number of digits
xihitrchdg o
roguerakudev And obviously I want it to prefer the more specific case

antononcube @Rog Hmm... I think I asked a similar question here a year ago, while dealing with time interval specs. 19:00
@Rog Not much help, but here is the discussion start: discord.com/channels/5384078799804...4753932288 19:08
Basically, I solve this by having a given operator in order to handle the generic and particular cases in one sub / method. 19:10
@Rog See the method process-time-interval definition and its invokation here: github.com/antononcube/Raku-DSL-Sh...kumod#L171 19:18
librasteve Rog: given this is raku, I would guess that its the same as any other regex 19:23
Util I have been asked to call your IRC attention to www.reddit.com/r/rakulang/comments...onference/ , if there is any chance you might be attending the conference. 20:36
Summary: (1) we want more Raku talks. (2) Rakudo internals qualifies for the Science track (paper or poster). Thanks!

[Coke] There should be a raku flag to hide the deprecated warnings. 21:14
librasteve i disagree - the warnings should be default not shown when running a script - only on install 21:15
they are too heavy (imo) for install too - one line total would be sufficient 21:17
this came from an errant module during the install...

I like having the deprecation warnings with an option to disable them at runtime (probably from years of java usage) - The PR was an easy way to help fix your short term issue, though. 21:29
I certainly agree that they are verbose and could possibly be shorter. 21:30

antononcube @Coke and @librasteve I review and merge the fixes tonight. Thank you! 21:39
