Module: Belt::Inflector

Defined in:
lib/belt/inflector.rb

Overview

Provides proper English inflection rules (pluralize, singularize, classify, etc.) via ActiveSupport::Inflector. Used throughout Belt for resource name derivation.

ActiveSupport is already a transitive dependency (via activeitem → activemodel → activesupport) so this adds zero new weight.
