Environ is a Ruby gem that lets you access environment variables in an object oriented manner. Instead of using ENV['VARIABLE']
, Environ lets you do Environ.env_variable
.
Add this line to your application's Gemfile:
gem 'environ'
And then execute:
$ bundle
Or install it yourself as:
$ gem install environ
Let's say you want to access the PATH variable. You could do:
ENV['PATH']
With Environ, you can access it OOP style with:
Environ.env_path
You can also set values if you need to:
Environ.env_path = 'new_path'
If you set a variable and need to reset everything, you can call:
Environ.reset!
You can also access all the keys in the environment with:
Environ.all
This will return a hash of all the environment variables.
If you choose to live on the edge, you can also disable no-conflict support and access variables directly by their ENV name:
Environ.no_conflict = false
path = Environ.path
No conflict is true by default to prevent unexpected results.
Finally, Environ respects accessing variables that may not be set. If you call something like Environ.env_doesnt_exist
it will return nil rather than throw an exception.
