as-cli-arguments - stringify a Capture as command-line arguments


use as-cli-arguments;
sub MAIN(|c) { say as-cli-arguments c, :named-anywhere }
use as-cli-arguments;
my %*SUB-MAIN-OPTS = :named-anywhere;
sub MAIN(|c) { say as-cli-arguments c }

sub MAIN(*@pos, :$foo, :$bar, *%_) {
    die "Found unexpected named arguments: &as-cli-arguments(%_)"
      if %_;


as-cli-arguments exports a single subroutine as-cli-arguments that takes either a Capture object or a hash with named arguments, and returns a string that represents the contents of the Capture as command line arguments.

If a Capture object is specified, then The subroutine also takes an optional named arguments :named-anywhere to indicate whether or not the "named arguments anywhere" mode should be assumed. By default, this will use the %*SUB-MAIN-OPTS<named-anywhere> setting, if available. Else it will default to False.

This is mainly intended as a helper subroutine for command-line scripts and modules that want to give feedback about the given or perceived or unexpected command line parameters.
