Class Method Details

.install ⇒ Object

Depending on ‘ActiveSupport::VERSION`, `::install` determines the manner in which acronyms are handled, then it redefines the `ActiveSupport::Inflector::underscore` method to use the `FastUnderscore` native extension. It leaves the existing `ActiveSupport` monkeypatch on `String` that allows it to call into the newly redefined `Inflector` method.
