def _add(path)
  return unless File.file?(path) && File.basename(path) == 'controller.rb'

  # Temporarily set path variables.
  @_stasis.path = path

  # Change current working directory.
  Dir.chdir(File.dirname(path))
  
  # Evaluate `controller.rb`.
  instance_eval(File.read(path), path)

  # Unset temporary path variables.
  @_stasis.path = nil
end

#_resolve(path, force = false) ⇒ Object

Accepts three kinds of paths as the ‘path` parameter:

  • Absolute: ‘/project/path/view.haml`

  • Relative: ‘view.haml`

  • Root: ‘/path/view.haml`

Returns an absolute path.

Set the ‘force` parameter to `true` to return the resolved path even if no file exists at that location.
