# File 'lib/stable.rb', line 13

def configuration
  @configuration ||= Configuration.new
end

.configure {|configuration| ... } ⇒ Object

Yields:

def enabled?
  Thread.current[:stable_enabled] || configuration.enabled || false
end

.recording ⇒ Object

this method is a block-based way to enable and disable recording of facts. It ensures that recording is turned on for the duration of the block and is automatically turned off afterward, even if an error occurs.

example:

Stable.recording do
  # code in here will be recorded
end

  disable!
  storage.close if storage.respond_to?(:close)
  @storage = nil
end

.storage ⇒ Object

# File 'lib/stable.rb', line 37

def storage
  @storage ||= (configuration.storage_path && File.open(configuration.storage_path, 'a+')) || raise("Stable.storage must be set to an IO-like object")
end

.storage=(io) ⇒ Object

# File 'lib/stable.rb', line 33

def storage=(io)
  @storage = io
end

.verify(record_hash) ⇒ Object

# File 'lib/stable.rb', line 105

def verify(record_hash)
  Fact.from_jsonl(record_hash.to_json).run!
