# 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
|

|
|
```
