I think it's best that I show you examples from the official documentation. Let's use chdir as our example.
https://docs.raku.org/routine/chdir chdir has the following signature: sub chdir(IO() $path, :$d = True, :$r, :$w, :$x --> IO::Path:D) So let's break this down. $path :: This is a positional parameter. You know it's positional because of a lack of preceding colon (:) :$d :: This is a named parameter w/ a default value of True :$r :: This is a named parameter :$w :: This is a named parameter :$x :: This is a named parameter So let''s try it! # Just the positional parameter chdir('/tmp'); # Both positional and named parameter ':d' set to False chdir('/tmp', :d(False)); # Again, both positional and named, but this time with named parameters ':d' set to False and ':x' set to True. ':x' is enough to set to True .. you can alternatively do a ':x(True)'. chdir('/tmp', :d(False), :x; # Same as last one, though named parameter order doesn't matter. chdir('/tmp', :x, :d(False)); Now quickly imagine you had a variable set to False like the following: my $d = False; I could instead have written the above examples like the following (in the order the above was written): chdir('/tmp'); chdir('/tmp', :$d); chdir('/tmp', :$d, :x); chdir('/tmp', :x, :$d); If you desire another example, please let me know. I believe given your latest comment and this latest example, that would be enough. If not, I'll happily provide another one. ~Paul On Sun, Feb 9, 2020 at 5:20 PM ToddAndMargo via perl6-users < perl6-us...@perl.org> wrote: > On 2020-02-08 15:39, Paul Procacci wrote: > > sub a(:$a, :$b, :$c) {} > > > > a(:c(1), :a(0), :b(3)); > > Hi Paul, > > I think I got it, but would yo give me one more exampale > to make sure I fully understand? > > sub a(:$a, :$b, :$c) {} > > a(:c(1), :a(0), :b(3)); > > But with two that are not named and two that are named. > And what is the order? > > > Many thanks, > -T > -- __________________ :(){ :|:& };:
