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: swiftc-ast.rb
    path of file: ./repos/Cleanse/cleansec/script
    
    the code of the file until where you have to start completion: #!/usr/bin/env ruby

require 'pathname'
require 'fileutils'

DISALLOWED_ARGUMENTS = {
    
    
def main
	input = ARGV
	og_command = [swiftc_executable] + input
	ast_input = input.clone
	indices_to_remove = strip_disallowed_arguments(DISALLOWED_ARGUMENTS, ast_input).flat_map do |idx|
		if DISALLOWED_ARGUMENTS[input[idx]] == :arg
			[idx, idx+1]
		else
			[idx]
		end
	end
