I thought to make an simple server http server with some console extension. I found the snippet to read from command line data.
var i = rl.createInterface(process.stdin, process.stdout, null);
i.question('Write your name: ', function(answer) {
console.log('Nice to meet you> ' + answer);
i.close();
process.stdin.destroy();
});
well to ask the questions repeatedly, i cant simply use the while(done) { }
loop? Also well if the server receives output at the question time, it ruins the line.
you can't do a "while(done)" loop because that would require blocking on input, something node.js doesn't like to do.
Instead set up a callback to be called each time something is entered:
var stdin = process.openStdin();
stdin.addListener("data", function(d) {
// note: d is an object, and when converted to a string it will
// end with a linefeed. so we (rather crudely) account for that
// with toString() and then trim()
console.log("you entered: [" +
d.toString().trim() + "]");
});
