| thowe | how do I take something like "my $block = { put $_ }" and feed it an array to iterate over? | 00:06 | |
| feed @array to $myblock? | 00:07 | ||
| MasterDuke | m: my &block = { put $_ }; my @array = <a b c>; @array.map(&block) # you mean something like this? | 00:10 | |
| camelia | a b c |
||
| thowe | so, use "map"? | 00:11 | |
| yeah, map works. That had actually occurred to me and somehow I was convinced Isaw a way to do it by using -> and I guess I didn't. | 00:12 | ||
| I love how Raku tells me I am wrong because I am trying to do Perl 5 things... | 00:14 | ||
| Raku doesn't really seem to care if I use $myblock or &myblock, which makes me wonder which is actually "more" correct. | 00:15 | ||
| MasterDuke | when you're kind of telling it what to do it doesn't matter as much. but for example, using the "right" sigil matters more if you're passing it to a multi-sub/method with candidates for a callable or not | 00:17 | |
| thowe | hm, yeah, OK | 00:19 | |
| guifa | m: my $block = { say "peso" }; my &block = { say "amp" }; $block; block | ||
| camelia | WARNINGS for <tmp>: amp Useless use of $block in sink context (line 1) |
||
| guifa | m: my $block = { say "peso" }; my &block = { say "amp" }; sink $block; sink block | 00:20 | |
| camelia | amp | ||
| guifa | when you assign to &var, you can call it just like any other sub. If you assign to a $var, to call, you'll need to explicitly use parenteses, e.g. $block(1,2,3), vs being able to just do block 1, 2, 3 if you've ampersanded it | 00:22 | |
| thowe | ah.. lemme play with that. | 00:28 | |
| looks like need to use colon... | |||
| "@speeds.map: &speedkb;" works, "@speeds.map &speedkb;" no work. | 00:29 | ||
| which is prob to be expected... | |||
| guifa | yeah, you need the colon because the colon is used to separate a method from its arguments if you go without parentheses | 01:29 | |
