| [Coke] | progressives. | 22:38 | |
| I should be able to use them everything but STILL find it's easier to take them off for very close cell phone stuff | |||

| tbrowder | thanks! | 23:22 | |
| back to raku: what do y'all recommed as the easiest way (least amount of code) to pass the common set of named parameters (and their values, if any) from one calling routine to each of two other routines? | 23:27 | ||
| the other two may not be strictly multi subs. | 23:29 | ||
| Voldenet | my fav way to do that is to use a class with args, not sure if it's short | 23:38 | |
| m: sub one(:$x, :$y) { say ($x, $y) }; sub two (:$x, :$y) { one :$x, :$y }; two :3x, :4y # nothing clever version, just raw arg-passing | |||
| camelia | (3 4) | ||
| Voldenet | m: class A { has $.x; has $.y; }; sub one(A $a) { say ($a.x, $a.y) }; sub two (A $a) { one $a }; two A.new(:3x, :4y) # slightly longer, but only if your arguments are $x and $y | 23:40 | |
| camelia | (3 4) | ||
| Voldenet | it depends what the common part is | ||
| m: sub one(:$x, :$y) { say ($x, $y) }; sub two (*%common) { one |%common }; two :3x, :4y # another version | 23:41 | ||
| camelia | (3 4) | ||
| Voldenet | m: sub one(:$x, :$y, :$z) { say ($x, $y, $z) }; sub two (*%common) { one |%common, :5z }; two :3x, :4y # allows adding args on top of it… | 23:43 | |
| camelia | (3 4 5) | ||
| Voldenet | m: sub one(:$x, :$y, :$z) { say ($x, $y, $z) }; sub two (:$z, *%common) { one |%common }; two :3x, :4y, :6z # or deducing if you explicitly don't want to pass something | ||
| camelia | (3 4 (Any)) | ||
| Voldenet | however `*%thing` feels difficult to maintain in the long run, class can have another validation and stuff like that on top of it | 23:46 | |
| wayland76 | Is there a nice way to go "for @array -> $item {}" but also access the array index in the loop? | 23:50 | |
| timo | you can @array.pairs to get a pair in your $item or $_, you can @array.kv and iterate two at a time | 23:51 | |
| m: my @a = <a b c d>; for @a.kv -> $i, $item { say "$i is $item" } | |||
| camelia | 0 is a 1 is b 2 is c 3 is d |
||
| Voldenet | you can make the syntax shorter if you really want | 23:53 | |
| m: sub bah(@x) { @x.kv.map( -> $k, $i { $i but $k }); }; my @a = <a b c d>; for @a.&bah -> $item { say $item; say $item.Int } | 23:54 | ||
| camelia | a 0 b 1 c 2 d 3 |
||
| Voldenet | but the syntax with .kv is saner | 23:55 | |
