Thanks. I take it you are referring to the "hyper" operator (?) It looks 
good, but it doesn't quite work:

 my $d = "hello \"there world\"";
my @f = << $d >>;
 @f[1] ; # "there


As it happens, I did manage to create a grammar that respects quoting, 
and even escaped quoting:


grammar Shlex {
token TOP {<.ws>? (|)* <.ws>?}
token ws { \s+ }
rule word { <[a..zA..Z0..9\\-]>+ }
token ascii_char { <-["\\]> } # anything not a " or \
token escaped_char { "\\\"" } # literal \"
token qstring { '"' [|]* '"' <.ws>?  }
}

my $m = Shlex.parse(Q[goodbye "\"cruel\" world"  ]);
say "First  component:$m[0][0].Str()"; # OUTPUT: First  component:goodbye
say "Second component:$m[0][1].Str()"; # OUTPUT: Second component:"\"cruel\" 
world"

If you haven't yet, you might want to look into a CSV parser. I think that
if you configure one of those to split on whitespace, that should give you
the results you want.

(Now with added reply all.)

Is there a bash/shlex-like processor with double-quotes handling?

[Mark Carter]

Is there a function that can decompose a string to an array separated by 
whitespace, but also respecting double quotes, and prefereably escape 
sequences?


So, for example:

my $d="hello   \"cruel world\"";

something-something($d) ; => ("hello", "cruel world")
