Method: Tap::Env#initialize

Defined in:
lib/tap/env.rb

#initialize(config_or_dir = Dir.pwd, context = {}) ⇒ Env

Initializes a new Env linked to the specified directory. Configurations for the env will be loaded from the config file (as determined by the context) if it exists.

A configuration hash may be manually provided in the place of dir. In that case, no configurations will be loaded, even if the config file exists.

Context can be specified as a Context, or a Hash used to initialize a Context.
