rypervenche I'm trying to figure out how to take a bag and get the weights in descending order and then map the key and values to variables, but I'm having trouble figuring it out. I've got: $bag.antipairs.sort(-*.key).map: -> but I'm not sure what signature will get me what I want. I think I need to decont it, but can't find the right combination. 03:52
03:56 mowcat left 03:59 zacts left
parabolize rypervenche: I'm not sure what you want the variables to be. maybe this? 04:09
:m say [ bag( < a a a b b c c c c >).pairs.sort(-*.values) ]
rypervenche So I got it to work with 2 for loops, but I feel like it could be done in a single map somehow. I'm trying to get the (sorted) weight and value into variables to be used later: gist.github.com/rypervenche/1d3e0a...c242899bce 04:14
guifa2 can I get some sample data to run with that? 04:28
rypervenche It's from a larger script with a few different data sources. I'll come up with a small example tomorrow to simply things. 04:31
guifa2 m: my $bag = Bag.new(<a d a b a c a d a a a b b b b b c a c c d d d>); for $bag.pairs.sort(-*.value) -> (:$key, :$value) { say "$key ($value)" } 04:33
camelia a (8)
b (6)
d (5)
c (4)
guifa2 That should work 04:34
and if you prefer different variable names
-> ( :key($new-key-name), :value($new-value-name) )

rypervenche guifa2: Thanks! That's exactly what I was looking for. I know you've shown me the syntax before, but I couldn't remember it or find it anywhere. :P 13:09
JJAtria[m] Is there a Raku equivalent to weak refs? I'm thinking of how they are used in eg. Perl to avoid memory leaks. Or is that something that doesn't translate to Raku? 13:25
13:30 skids joined 13:32 domidumont left
moritz Raku uses a "proper" garbage collector (not ref counting), so you don't need to avoid circular data structures 13:38
there are some *very* few cases where you could still use weak references; I don#t think we have a good solution for that yet 13:39
andrzejku hey guys 13:49
do you know how raku gaming stands now? 13:50

rypervenche Is it possible to use gather/take with a map? For example, I'm looping through some lines in an array and only taking items if they match a certain criteria and then assigning all of that to a variable. I've got it working with a for loop right, but haven't been able to figure out how to do it with a map (so I can hyper it). I'll give an example of the code so it makes more sense. 21:15
MasterDuke you probably want a grep? 21:17
timotimo you can also hyper a for, it has to be a "hyper for", though 21:19
rypervenche The portion of code in question: gist.github.com/rypervenche/326be5...eb38fde7af
I converted it to a map with a hyper, but I couldn't find any place to put a gather. 21:20
hyper for :O
Hmm, I can't change batch and degree though when using "hyper for", can I? 21:23
timotimo you can, you'll need to "hyper for @blah.hyper(...) { ... }"
rypervenche Ahhh 21:24
21:24 dudz left 21:33 |oLa| left 21:44 aluaces left
rypervenche Hmmm, gather still doesn't work when I use hyper for. I get "Died at: take without gather" 21:49
timotimo oh 21:50
i should have pointed this out before 21:51
with gather/take where you're take-ing from hypered workers, you would be accessing an array concurrently
that's a big no-no
you can return an array from each map or for block and slurp them all together afterwards, or send values to a Channel 21:52
Xliff You'd need a Lock
Channel would be better, I suspect

Xliff Who is handling raku support for Repl.it? 22:08
rypervenche: Any luck? 22:21
rypervenche Haven't started yet. I'll have to reorganize it a bit in my test to work with promises. 22:25
guifa had to do an assignment for his CS class in Java and it was ugly 22:26
Xliff You shouldn't need any promises. Just a channel.
See my comment on your gist.
guifa In Raku I could have done it in like five 20-char max lines
unclechu hey, is there any way to define some text for `--help` with line breaks? smth like #|«…» before MAIN function would associate it with particular multi-sub pattern and would remove any line breaks 22:27
I want to add some generic description 22:28
Xliff unclechu: Write a sub USAGE { } that adds to $*USAGE var
22:30 lucasb left
Xliff unclechu: See here github.com/Xliff/p6-GtkPlus/blob/m...xample.pl6 22:30
unclechu Xliff: thanks! 22:31
Xliff unclechu: Live sample -- repl.it/@Xliff/PersonalModernRobots#main.raku 22:33
rypervenche Xliff: Oooh, I'll try that out. 22:34
Xliff unclechu: Check the repl.it again. It's cleaner
unclechu Xliff: why does example from the first link uses `nqp` in order to concatenate string with `$*USAGE`?
Xliff Old code
Back when I originally wrote this, that was the only way to access $*USAGE. It's unnecessary, now 22:35
unclechu Xliff: okay, i just realized i don’t need nqp there
Xliff Oops! Sure don't. ;) 22:36
rypervenche Xliff: Out of curiosity, couldn't I replace (my $s = $c.Supply).tap with $c.Supply.tap ?
I don't see you using the $s anywhere else in the gist. 22:37
Xliff rypervenche: I was wondering about that. The only reason I assign to $s is to make sure the Supply object doesn't fall out of scope.
That might not be necessary

stanrifkin AlexDaniel: sub f($a, $b, $c) are three arguments and sub f ($a, $b, $c) is one argument i. e. a list with my understanding... 23:12
AlexDaniel stanrifkin: yes, but what would be the alternative design choice? 23:13
stanrifkin AlexDaniel: in perl i used sub f(\@arr) for that... maybe than something like sub f(\($a, $b, $c)) but maybe that's more irritating 23:14
AlexDaniel ahh 23:15
stanrifkin :)
AlexDaniel actually would've been interesting to have no list type, just mutable arrays. Then () syntax would not be there, so f (42, 43) could be a function call 23:17
edgy, I know, but it's a possibility :) 23:18
not the most wonderful possibility though :P 23:20
stanrifkin: there was a discussion some years ago about the preferred style for sub declaration 23:21
stanrifkin: actually, rereading this conversation, I'm not entirely sure what we're talking about exactly :) 23:22
Grinnz thinks its better than spaces having no syntactical significance
AlexDaniel stanrifkin: thing is, `sub foo () {}` is actually valid
so you can define your subs this way, but you cannot use the same syntax to call them 23:23
Grinnz in perl say (something)[0] attempts to run say(something) and then has a syntax error, because that makes sense :P 23:24
AlexDaniel a lot of people prefer the space for some reason, but IIRC even more people argued that the preferred style should be without a space, this way I guess you're less likely to assume that it'd be valid to call your subs this way
Grinnz i very much prefer requiring no space between symbol and opening parentheses for calls 23:25
because that solves taht ambiguity in particular
in raku it's more complicated since it actually means something different
timotimo there's always slang::tuxic to do the space thing differently 23:30
stanrifkin AlexDaniel: I missed the point that defining the sub the space is valid. OK. I get used to that. 23:33
23:33 guifa left 23:34 guifa joined
AlexDaniel timotimo: and how is that useful in practice? 23:34
timotimo dunno, i didn't read enough of the discussion i guess 23:35
AlexDaniel timotimo: it's not about the discussion, but about the whole idea
of having modules that introduce slight syntax changes
timotimo if you don't like a (1, 2) being one argument, use slang::tuxic and it no longer is that way, hooray 23:36
AlexDaniel and then say you go to work, and what happens? You convince all your colleagues to add `use Slang::Tuxic` to all of the files? 23:37
or you don't, and then you'd probably be writing it the wrong way by acciddent
Slang::Tuxic is a party trick, that's it 23:38
timotimo hm, does tuxic break when you use it inside curlies? 23:39
AlexDaniel slangs are fantastic for relatively big features, say inline SQL or anything like that. But suggesting to use them for minor syntax differences is just out of touch 23:40
because what we have here is actually a trap in the language. If we had Raku::Critic I guess it would've been easy to add a check for that, but it seems like we're missing an alternative also 23:42
for example, say you write `foo (1, 2, 3)`. Then Raku::Critic could've warned you about it because maybe you didn't mean it
but… what would it say? 23:43
23:43 pduh joined
AlexDaniel like how can you write explicitly that you meant it. foo((1, 2, 3)) ? Ew. 23:43
timotimo m: sub foo(*@x) { dd @x }; foo\ (1, 2, 3) 23:44
camelia Array element = [1, 2, 3]
timotimo m: sub foo(*@x) { dd @x }; foo (1, 2, 3)
camelia Array element = [1, 2, 3]
timotimo m: sub foo(*@x) { dd @x }; foo(1, 2, 3)
camelia Array element = [1, 2, 3]
timotimo ah, right
AlexDaniel yeah, that's the opposite I think :)
timotimo m: sub foo(**@x) { dd @x }; foo (1, 2, 3); foo\ (1, 2, 3); foo(1, 2, 3); foo((1, 2, 3))
camelia Array element = [(1, 2, 3),]
Array element = [1, 2, 3]
Array element = [1, 2, 3]
Array element = [(1, 2, 3),]
timotimo right, it is
AlexDaniel not enough ASCII parens, I guess 23:46
or maybe an optional colon could've done it
foo: (1, 2, 3) 23:47
sure, that's a label, but I don't know why labels need to have this neat syntax :
:)
