multi method print(--> Bool)
Prints value to
$*OUT after stringification using
.Str method without adding a newline at end.
"abc\n".print; # OUTPUT: «abc␤»
From Independent routines
multi sub print(** --> True)multi sub print(Junction --> True)
Prints the given text on standard output (the
$*OUT filehandle), coercing non-Str objects to Str by calling
.Str method. Junction arguments autothread and the order of printed strings is not guaranteed.
print "Hi there!\n"; # OUTPUT: «Hi there!␤»print "Hi there!"; # OUTPUT: «Hi there!»print [1, 2, 3]; # OUTPUT: «1 2 3»print "Hello" | "Goodbye"; # OUTPUT: «HelloGoodbye»
To print text and include the trailing newline, use
method print(Proc::Async: Str() , : = )
Write the text data in
$str 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 print, otherwise an X::Proc::Async::MustBeStarted exception is thrown.
multi method print(** --> True)multi method print(Junction --> True)
Writes the given
@text to the handle, coercing any non-Str objects to Str by calling
.Str method on them. Junction arguments autothread and the order of printed strings is not guaranteed. See write to write bytes.
Attempting to call this method when the handle is in binary mode will result in
X::IO::BinaryMode exception being thrown.
my = 'path/to/file'.IO.open: :w;.print: 'some text';.close;
method print(IO::Socket: Str(Cool) )
Writes the supplied string to the socket, thus sending it to other end of the connection. The binary version is method write.
Fails if the socket is not connected.
multi method print(|)
method print(Str --> Promise)
Attempt to send
$str on the IO::Socket::Async that will have been obtained indirectly via
listen, returning a Promise that will be kept with the number of bytes sent or broken if there was an error sending.
