Overview

Runtime environment

Runtime environment objects inherit from OpenStruct but feature some extensions:

  • Use replace to replace the current key/value table with the given hash.

  • Use merge to merge the given hash into the current key/value hash.

  • When reading a value using square brackets, the key is implicitly converted to Symbol.

Examples:

AIPP.config                      # => AIPP::Environment::Config
AIPP.config.foo                  # => nil
AIPP.config.foo = :bar           # => :bar
AIPP.config.replace(fii: :bir)
AIPP.config.foo                  # => nil
AIPP.config.fii                  # => :bir
AIPP.config.read!                # method defined on Config class
