RVM Ruby Execution with launchctl on osx

This addresses a problem that goes like this:

You want to create a launch file for launchd (launchctl) to run a ruby file periodically or as a daemon.

Various solutions to this problem include creating an RVM alias for the particular ruby version you want to use. Here I present a working version without aliases, just uses the default RVM Ruby. Please not that, for me, the default rvm ruby is 2.2.5.

When you create a sample plist file like this:



The rvm environment does get initialized. You get lots of gem issues.

The trick here lies in not running ruby but:

rvm-shebang-ruby

Simply use:

Ruby and RVM environments are now correctly updated.

Yeah and you don't need to create any aliases. It will work perfectly fine.
