sailkite i don't have a strong reason for asking this, but is there a way to use the reduction metaoperator with infix feed operators? i've tried naïve variations and i'm clearly not groking something 17:08
17:09 Guest4085 left 17:21 arkiuat joined 17:27 arkiuat left
ab5tract sailkite: one way to get things working with feeds is to wrap them in a block that calls itself 17:35
m: dd do 1..10 ==> { [+] @_ }() 17:36
camelia 55
ab5tract But also in RakuAST you could use a helper class to make it read a bit more nicely 17:37
m: Q| my $r = class :: { method reduce(*@a) { [+] @a } }.new; dd do 1..10 ==> reduce($r:) 17:38

Couldn't find terminator | (corresponding | was at line 1)

------> @a } }.new; dd do 1..10 ==> reduce($r:)<HERE><EOL>
expecting any of:

ab5tract m: Q| my $r = class :: { method reduce(*@a) { [+] @a } }.new; dd do 1..10 ==> reduce($r:) |.AST.EVAL
camelia 55
ab5tract or less cryptically: 17:40
m: Q| class Assist { method reduce(*@a) { [+] @a } }; dd do 1..10 ==> reduce(Assist:) |.AST.EVAL

sailkite i guess in an extremely arcane and purely didactic sense, i was wondering about a hypothetical case where there's some concept like this raku my @things = 2, 1, 2; @things ==> unique() ==> sort() ==> say(); and i wanted to somehow manipulate that into a means of using [==>]. i know that it's possible to just simply method chain it @things.unique.sort.say, but i couldn't help but feel curious. 18:05
ab5tract Ah, so that's what you meant :) 18:22
18:23 arkiuat joined
ab5tract I don't think that's possible because there's no way to pass the call in a list (as far as I know, anyway!) 18:24
so even if you could do: [==>] @a, unique(), sort(), say() -- it would fail because you would have the result of those calls in the list instead
but as you've noticed, [==>] and other attempts won't work either because the feed operator is not a higher level Raku infix routine, even though it dresses like one for the party 18:26

nahita3882 with explicit .reduce there is something, but not that dramatic: 18:30
m: my @a = 12, 3, 4, 3; [@a, &unique, &sort, &say].reduce: { &^fun(@^arg) } 18:31
Raku eval (3 4 12)
nahita3882 order-preservingness of .unique is appreciated; in CPython, e.g., one does [*dict.fromkeys(arr)] to that effect (PyPy guarantees [*set(arr)] is ok) 18:36

habere-et-disper Is there a simple/portable way to test from raku if the terminal supports non-ASCII? I'm writing to STDOUT and I want to know if it can handle UTF8. 19:59
