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: slim.rb
    path of file: ./repos/nanoc/nanoc/lib/nanoc/filters
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Nanoc::Filters
  # @api private
  class Slim < Nanoc::Filter
    identifier :slim

    requires 'slim'

    # Runs the content through [Slim](http://slim-lang.com/).
    #
    
    def run(content, params = {})
      params = {
        disable_capture: true, # Capture managed by Nanoc
        buffer: '_erbout', # Force slim to output to the buffer used by Nanoc
      }.merge params

      # Create context
      context = ::Nanoc::Core::Context.new(assigns)

      ::Slim::Template.new(filename, params) { content }.render(context) { assigns[:content] }
    end
