Documentation for routine
say assembled from the following types:
multi method say(--> Bool)
Prints value to
$*OUT after stringification using gist method with newline at end. To produce machine readable output use
say 42; # OUTPUT: «42␤»
multi sub say(** --> True)
.gist method of some objects, such as Lists, returns only partial information about the object (hence the "gist"). If you mean to print textual information, you most likely want to use
say Range; # OUTPUT: «(Range)␤»say ; # OUTPUT: «(Foo)␤»say 'I ♥ Perl6'; # OUTPUT: «I ♥ Perl6␤»say 1..Inf; # OUTPUT: «1..Inf␤»
multi method say(IO::Handle: ** --> True)
Attempting to call this method when the handle is in binary mode will result in
X::IO::BinaryMode exception being thrown.
my = open 'path/to/file', :w;.say(Complex.new(3, 4)); # RESULT: «3+4i\n».close;
multi method say(|)
method say(Proc::Async: , : = )
gist on the
$output, adds a newline, encodes it as UTF-8, and sends it to the standard input stream of the external program, encoding it as UTF-8.
Returns a Promise that will be kept once the data has fully landed in the input buffer of the external program.
Proc::Async object must be created for writing (with
Proc::Async.new(:w, $path, @args)). Otherwise an X::Proc::Async::OpenForWriting exception will the thrown.
start must have been called before calling method say, otherwise an X::Proc::Async::MustBeStarted exception is thrown.
