Method: Linecook::Recipe#attributes

Defined in:
lib/linecook/recipe.rb

#attributes(source_name = nil, &block) ⇒ Object

Loads the specified attributes file and merges the results into attrs. A block may be given to specify attrs as well; it will be evaluated in the context of an Attributes instance.

Returns a hash representing all attributes loaded thusfar (specifically attrs prior to merging in the package env). The attributes hash should be treated as if it were read-only.
