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: decrement.rb
    path of file: ./repos/truffleruby/bench/liquid/lib/liquid/tags
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Liquid
  # 
    
    def render_to_output_buffer(context, output)
      value = context.environments.first[@variable] ||= 0
      value -= 1
      context.environments.first[@variable] = value
      output << value.to_s
      output
    end
