Instance Method Details

#camelize(basename, _abspath) ⇒ Object

Very basic snake case -> camel case conversion.

inflector = Zeitwerk::Inflector.new
inflector.camelize('post', ...)             # => 'Post'
inflector.camelize('users_controller', ...) # => 'UsersController'
inflector.camelize('api', ...)              # => 'Api'

Takes into account hard-coded mappings configured with ‘inflect`.

  overrides[basename] || basename.split('_').each(&:capitalize!).join
end

Configures hard-coded inflections:

inflector = Zeitwerk::Inflector.new
inflector.inflect(
  'html_parser'   => 'HTMLParser',
  'mysql_adapter' => 'MySQLAdapter'
)

inflector.camelize('html_parser', abspath)      # => 'HTMLParser'
inflector.camelize('mysql_adapter', abspath)    # => 'MySQLAdapter'
inflector.camelize('users_controller', abspath) # => 'UsersController'
