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

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 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.

Getting Started

Install the module with: npm install exit

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");

In Windows, clone the repo and cd to the test\fixtures directory. The only difference between log.js and 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.
