Copy stdin to stdout: Difference between revisions

=={{header|Wren}}==

In the following script, stdin and stdout are both assumed to be connected to a terminal.

Bytes are read from stdin and written to stdout until the return key is pressed.

<lang ecmascript>import "io" for Stdin, Stdout

Stdin.isRaw = true // prevents echoing to the terminal

while (true) {

var byte = Stdin.readByte() // read a byte from stdin

if (byte == 13) break // break when enter key pressed

System.write(String.fromByte(byte)) // write the byte (in string form) to stdout

Stdout.flush() // flush output

}

System.print()

Stdin.isRaw = false</lang>
