Module: Evoke::Inflections::Camelize

Defined in:
lib/evoke/inflections/camelize.rb

Overview

String inflections for converting to CamelCase.

Camelizing a string takes all the compound words separated by an underscore and combines them together, capitalizing the first letter of each word. It also converts ‘/’ to ‘::’. For example “hello_world” is camelized to “HelloWorld”, and “hello/world” is camelized to “Hello::World”.
