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


code

=begin code :lang<raku>

use as-cli-arguments;
sub MAIN(|c) { say as-cli-arguments c, :named-anywhere }

=end code


=begin code :lang<raku>

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

=end code


as-cli-arguments exports a single subroutine C<as-cli-arguments> that takes
a C<Capture> object, and returns a string that represents the contents of
the C<Capture> as command line arguments.


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