Method: LibGems::Specification.attribute_alias_singular

Defined in:

lib/libgems/specification.rb

.attribute_alias_singular(singular, plural) ⇒ Object

Defines a singular version of an existing plural attribute (i.e. one whose value is expected to be an array). This means just creating a helper method that takes a single value and appends it to the array. These are created for convenience, so that in a spec, one can write

s.require_path = 'mylib'

instead of:

s.require_paths = ['mylib']

That above convenience is available courtesy of:

attribute_alias_singular :require_path, :require_paths
