You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: base.rb
    path of file: ./repos/tty-logger/lib/tty/logger/handlers
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module TTY
  class Logge
    
        def coerce_formatter(name)
          case name
          when String, Symbol
            const_name = if Formatters.const_defined?(name.upcase)
                           name.upcase
                         else
                           name.capitalize
                         end
