Ruby -=- Using environment variable

Hi

With Ruby, You can use environment variable by using the function.

ENV['JAVA_HOME']

The variable must be defined in the operating system.


Ruby have many places to define environment variable within the code. You can put environment variable common across environment in [RubyProject]/config/environment.rb

Also, if you want to define an environment variable for a specific environment, you can set the variable in [RubyProject]/config/environments/production.rb or test.rb or development.rb...

The variable defined in the project can be use directly. For example, if I put MY_VAR = 3 in the file environment.rb, I will use the variable directly by calling MY_VAR in the code. For example

p MY_VAR
