keypress
========

$3

Previous to Node v0.8.x, there was an undocumented "keypress" event that
process.stdin would emit when it was a TTY. Some people discovered this hidden
gem, and started using it in their own code.

Now in Node v0.8.x, this "keypress" event does not get emitted by default,
but rather only when it is being used in conjuction with the readline (or by
extension, the repl) module.

This module is the exact logic from the node v0.8.x releases ripped out into its
own module.

__Bonus:__ Now with mouse support!

Installation
------------

Install with npm:

`` bash
$ npm install keypress
`

Or add it to the "dependencies" section of your _package.json_ file.


Example
-------

#### Listening for "keypress" events

` js
var keypress = require('keypress');

// make process.stdin begin emitting "keypress" events
keypress(process.stdin);

// listen for the "keypress" event
process.stdin.on('keypress', function (ch, key) {
console.log('got "keypress"', key);
if (key && key.ctrl && key.name == 'c') {
process.stdin.pause();
}
});

process.stdin.setRawMode(true);
process.stdin.resume();
`

#### Listening for "mousepress" events

` js
var keypress = require('keypress');

// make process.stdin begin emitting "mousepress" (and "keypress") events
keypress(process.stdin);

// you must enable the mouse events before they will begin firing
keypress.enableMouse(process.stdout);

process.stdin.on('mousepress', function (info) {
console.log('got "mousepress" event at %d x %d', info.x, info.y);
});

process.on('exit', function () {
// disable mouse on exit, so that the state
// is back to normal for the terminal
keypress.disableMouse(process.stdout);
});
