| wafflus | how do you make a named command line argument to a raku program required and/or set a default value | 10:21 | |
| Str :n( :name( $name is required ) ) Unable to parse named parameter; couldn't find right parenthesis | 10:22 | ||
| i've tried ! as well as = | |||
| same error | |||
| ab5tract | m: sub MAIN(:n(:$name = “foo”)) { dd :$name }; MAIN(:n(“bar”)) | 11:11 | |
| camelia | ===SORRY!=== Error while compiling <tmp> Unable to parse named parameter; couldn't find right parenthesis at <tmp>:1 ------> sub MAIN(:n(:$name⏏ = “foo”)) { dd :$name }; MAIN(:n(“bar”) |
||
| ab5tract | Gar, copied the wrong invocation | 11:12 | |
| m: sub MAIN(:n(:$name) = “foo”) { dd :$name }; MAIN(:n(“bar”)) | |||
| camelia | :name("bar") :name("foo") |
||
| ab5tract | Second output with the default value is because I’ve forgotten the proper way to test MAIN in a one liner | 11:13 | |
| Defaults are not supported on required params | 11:14 | ||
| m: sub MAIN(:n(:$name)! = “foo”) { dd :$name }; MAIN(:n(“bar”)) | |||
| camelia | ===SORRY!=== Error while compiling <tmp> Cannot put default on required parameter $name at <tmp>:1 ------> sub MAIN(:n(:$name)! = “foo”⏏) { dd :$name }; MAIN(:n(“bar”)) expecting any of: constraint |
||
| ab5tract | wafflus: ^^ | 11:15 | |
| wafflus | k ty least i know | ||
| librasteve | i guess a default on a required parameter is incorrect and we want the compiler to tell us | 11:58 | |

| ab5tract | Defaults on a required parameter is indeed considered nonsensical, which I agree with | 16:25 | |
