Module: Iriq::Inflector

Defined in:
lib/iriq/inflector.rb

Overview

Singularization with a swappable adapter.

By default uses ActiveSupport's inflector if it can be required, otherwise falls back to BuiltinAdapter. Override globally:

Iriq::Inflector.adapter = MyAdapter   # must respond to .singularize(String)

And reset to default with Iriq::Inflector.reset_adapter!.
