| riffraff | hey everyone, forgive me for the dumb question, but I've just started to play with Raku :) . | 15:37 | |
| I was wondering, is there a way to apply an infix operator to all pairs in a list of pairs, other than explicitly using .map ? | |||
| I have this | |||
| (1,2,3,4).rotor(2 => 0).map: {$_[0] +$_[1]} | |||
| I can avoid unpacking $_ with reduce, | |||
| ...map: {[+] $_} | |||
| but I think there should be a way to compress the block with something like | |||
| ....map: infix:<+> | |||
| but I can't find the appropriate incantation :) | |||
| I also thought I could use | |||
| ....map: * + * | |||
| but the pair is not "unpacked" and so this doesn't work :/ | |||
| lizmat | m: dd (1,2,3,4).rotor(2 => 0).map: {$_[0] +$_[1]} | 15:41 | |
| camelia | (3, 7).Seq | ||
| lizmat | m: dd (1,2,3,4).rotor(2).map: {$_[0] +$_[1]} | ||
| camelia | (3, 7).Seq | ||
| lizmat | m: dd (1,2,3,4).rotor(2)>>.sum | ||
| camelia | (3, 7) | ||
| lizmat | riffraff ^^ | ||
| riffraff | right, but that works because of the list.sum method, it wouldn't work with > or % for example (I think?) | 15:43 | |
| lizmat | ah, indeed | ||

| qorg11 | Equivalent to write something like while((c = read(fd, buf, 256)) > 0 ) in raku? | 17:42 | |
| I did while $c > 0 { | |||
| $c = cread(...); | |||
| } | |||
| lizmat | "file".IO.open(:bin).read(256) | 17:45 | |
| ? | |||
| my $h = "1".IO.open(:bin); while $h.read(256) -> $buf { say $buf.elems } | 17:47 | ||
| ? | |||
| qorg11 | Well i didn't mean reading a file but setting a variable inside the while loop and evaluating it | 17:48 | |
| Like you can do while((readline("> ")) != NULL) | 17:49 | ||
| lizmat | my $c = 42; while $c { ... } | 17:52 | |
| ?? | |||
| my $c = 42; while $c != 666 { ... } | |||
| qorg11 | Can't i just use the return value from a function as the condition? | 18:29 | |
| And assign the return value (inside the condition) as the thing to evaluate? | |||
| Yeah just figured it out | 18:32 | ||
| ls.qorg11.net/files/QEeuRmhn/-.txt | |||
| ls.qorg11.net/files/piPpWJlR/-.txt that especifially | 18:33 | ||
| lizmat | True < 10 ? | 19:00 | |
| guess that's true | |||
| Nemokosch | what is this good for? | 19:04 | |
| SmokeMachine | m: dd (1,2,3,4).rotor(2).map: -> ($a, $b) { $a + $b } | 19:44 | |
