Dotenv

Garp understands dotenv files in your root, and will make its values available for use in the traditional ini files.

You can use them like this:

cdn.s3.apiKey = ${S3_APIKEY}
cdn.s3.secret = ${S3_SECRET}

Note, in a lot of cases this defeats the purpose of the cascading nature of Zend Framework's ini files.

Using .env on webservers

All you need to do on a webserver is move a .env file into the shared directory, and configure Capistrano as follows:

# in application/configs/deploy.rb

set :linked_files, fetch(:linked_files, []).push('.env')

This file will be linked in the root after every deploy.
