| Anton Antonov | How do you specify Whatever for CLI arguments scripts? Currently, I am using the string "Whatever" or empty string "". | 15:36 | |
| lucs | Not sure what you mean. Something like this? sub MAIN ($a, $, $b) { $a + $b} | 17:16 | |

| Anton Antonov | Something like sub MAIN ( Str $a, :$b = Whatever, Str :$c = 3 ) { $b.isa(Whatever) a ~ b !! a ~ $b.raku ~ $c } | 17:39 | |
| lucs | Uh, should there be a '??' before the 'a ~ b' there? | 17:44 | |
| Anton Antonov | Yes, of course. | 17:59 | |
| lucs | Yeah, okay. I'm still not sure what you're after, sorry :/ | 18:07 | |
| Nemokosch | It should be * instead of Whatever probably | 18:13 | |
| but no idea if that gets parsed via CLI | |||
| Anton Antonov | @Nemokosch Yes you got what I am asking. (I never tried using "*" 😲 .) | 18:16 | |
| Drudge Sentinel | Is running a MAIN subroutine a normal practice? In my admittedly trivial exercises, when I run a script with a MAIN subroutine it messes with the behavior of things like @*ARGS | 20:07 | |
| Nemokosch | why would you use @*ARGS if you can use the signature of MAIN? | 20:20 | |
| Drudge Sentinel | it was just mentioned in the exercise text itself: You’ve already used an Array that you haven’t seen. @*ARGS is the collection of Strs that you’ve specified on the command line. Output each element on its own line. | 20:32 | |
| I ended up just using $ cat ex6-8.raku for @*ARGS {.say} | 20:33 | ||
| I mostly just used it because it was mentioned as what I need to iterate over by the exercise | 20:34 | ||
| so i think a more generic application would look something like sub MAIN (*@args) { for @args {.say}; } after reading the command line interface docs in raku | 20:38 | ||
| lucs | @Drudge Sentinel You'll probably find this interesting: docs.raku.org/routine/MAIN | 20:40 | |
| Drudge Sentinel | yep, was just reading that when I came up with the latter code | 20:41 | |
