ENV into a
gem install home-dotenv # or in a Gemfile gem 'home-dotenv'
So, you have scripts run on your system and you have config variables for those scripts (keys, usernames, passwords, hostnames, etc).
A unified way to access those globals would be nice instead of hard-coding them or passing them as parameters.
So, now you can put all your variables in
~/.env like so:
SUPER_SECRET_PASSWORD=i-definitely-don-t-want-people-to-see-this AWS_KEY=abcdefgh SECRET_HOST=https://private.secret.com
Then, in your scripts:
require 'home-dotenv/load' # or require 'home-dotenv' HOME_ENV = HomeDotenv.parse # then require 'open-uri' open(HOME_ENV[:SECRET_HOST]).read
- if the line is empty or starts by "#" (comment), ignore
- otherwise, string before the first "=" is key, after that it's the value
- result is a hash indexed by symbol, e.g.
