Env vars

rbenv-vars is an rbenv plugin. To install it, simply clone git@github.com:sstephenson/rbenv-vars.git to your rbenv installation's plugin directory.

Once installed, it will look for a file called .rbenv-vars in your current working directory or any of its parent directories. To set environment variables, just define them as key/value pairs:

RAILS_ENV=production
SECRET_KEY_BASE=abc
API_KEY=def
