Setting exit code without calling process.exit()

[Will Conant]

Is it possible to set the exit code without calling process.exit? I find myself writing scripts that just run until the event loop is empty. Along the way, they might find error conditions and log them to STDERR. It would be convenient if I could decide what the exit code should be right when I find an error, rather than having to track all my callbacks and then call process.exit when everything is done. Any ideas?

Thanks!

Try `process.on('exit', function() { process.exit(currentErrorcode) })`

That loops infinitely, but it suddenly occurs to me that I could keep track of the fact that I called process.exit in the exit event and only do it once. Let me try that.

Yeah. That does the trick.

process.once() instead?

You should use process.reallyExit(currentErrorcode) instead of
process.exit(currentErrorcode) here.

Even better. Thanks!

I fixed process.exit(), it's now safe to call process.exit() from an
exit listener.
