    Metadata details:
    filename: compiler.rb
    path of file: ./repos/truffleruby/bench/sinatra/bundle/gems/mustermann-1.1.1/lib/mustermann/ast
    
    the code of the file until where you have to start completion: # frozen_string_literal: true
require 'mustermann/ast/translator'

        def pattern(capture: nil, **options)
          case capture
          when Symbol then from_symbol(capture, **options)
          when Array  then from_array(capture, **options)
          when Hash   then from_hash(capture, **options)
          when String then from_string(capture, **options)
          when nil    then from_nil(**options)
          else capture
