2.4.0

Features

New loaders

• Doppler support.

Just specify your Doppler service token in the DOPPLER_TOKEN env var, and Anyway would automatically download configuration from Doppler.

• ESJON support.

If you use EJSON to store encrypted secrets, Anyway would try to load configuration from config/secrets.ejson (and environment-specific .ejson files, too).

API enhancements

• You can now mark nested attributes as required:

class AppConfig < Anyway::Config
  attr_config :assets_host, database: {host: nil, port: nil}

  required :assets_host, database: [:host, :port]
end

• Predicate methods are automatically defined for attributes with the :boolean type.

• Added ability to use env_prefix "" to load data rom unprefixed env vars.

• Added Config#as_env to convert config values into a ENV-like Hash.

This can be useful to export configuration to be used with legacy tools relying on ENV. So, for example, you can load data from credentials, secrets, whatever and make it available via ENV.

Experimental features

• Sub-configs support via types.

class AnotherConfig < Anyway::Config
  attr_config foo: "bar"
end

class MyConfig < Anyway::Config
  attr_config :another_config

  coerce_types another_config: "AnotherConfig"
end

MyConfig.new.another_config.foo #=> "bar"

ENV["MY_ANOTHER_CONFIG__FOO"] = "baz"
MyConfig.new.another_config.foo #=> "baz"
