# exit [![Build Status](https://secure.travis-ci.org/cowboy/node-exit.png?branch=master)](http://travis-ci.org/cowboy/node-exit)

A replacement for process.exit that ensures stdio are fully drained before exiting.

To make a long story short, if `process.exit` is called on Windows, script output is often truncated when pipe-redirecting `stdout` or `stderr`. This module attempts to work around this issue by waiting until those streams have been completely drained before actually calling `process.exit`.

See [Node.js issue #3584](https://github.com/joyent/node/issues/3584) for further reference.

Tested in OS X 10.8, Windows 7 on Node.js 0.8.25 and 0.10.18.

Based on some code by [@vladikoff](https://github.com/vladikoff).

## Getting Started
Install the module with: `npm install exit`

```javascript
var exit = require('exit');

// These lines should appear in the output, EVEN ON WINDOWS.
console.log("omg");
console.error("yay");

// process.exit(5);
exit(5);

// These lines shouldn't appear in the output.
console.log("wtf");
console.error("bro");
```

## Don't believe me? Try it for yourself.

In Windows, clone the repo and cd to the `test\fixtures` directory. The only difference between [log.js](test/fixtures/log.js) and [log-broken.js](test/fixtures/log-broken.js) is that the former uses `exit` while the latter calls `process.exit` directly.

This test was done using cmd.exe, but you can see the same results using `| grep "std"` in either PowerShell or git-bash.

```
C:\node-exit\test\fixtures>node log.js 0 10 stdout stderr 2>&1 | find "std"
stdout 0
stderr 0
stdout 1
stderr 1
stdout 2
stderr 2
stdout 3
stderr 3
stdout 4
stderr 4
stdout 5
stderr 5
stdout 6
stderr 6
stdout 7
stderr 7
stdout 8
stderr 8
stdout 9
stderr 9

C:\node-exit\test\fixtures>node log-broken.js 0 10 stdout stderr 2>&1 | find "std"

C:\node-exit\test\fixtures>
```
