spotty v1.0.0

node-lookup-tty

Get the TTY device (e.g., /dev/pts/3) of the current node process

Usage

// A clone of the `tty` command
var tty = require('spotty');
tty(function(err, res) {
	if (err) {
		console.error("Error found: " + err.toString())
	} else {
		console.log(res)
	}
})

Approach

It's an ugly hack, but it should work. The idea is to call fstat on file descriptor 0, and then to call stat on all tty-like files in dev. Stop when we find one that matches fstat(0).

Limitations

Doesn't work on Windows. Should work on OSX and Linux, but needs some testing. Won't work if fd=0 isn't standard input connected to a TTY.
