    Usage: dead_end <file> [options]

    Parses a ruby source file and searches for syntax error(s) such as
    unexpected `end', expecting end-of-input.

    Example:

      $ dead_end dog.rb

      # ...

        ❯ 10  defdog
        ❯ 15  end
        ❯ 16

    Env options:

      DEAD_END_RECORD_DIR=<dir>

      When enabled, records the steps used to search for a syntax error to the
      given directory

    Options:
  EOM

  opts.version = DeadEnd::VERSION

  opts.on("--help", "Help - displays this message") do |v|
    puts opts
    exit
  end

  opts.on("--record <dir>", "When enabled, records the steps used to search for a syntax error to the given directory") do |v|
    options[:record_dir] = v
  end

  opts.on("--no-terminal", "Disable terminal highlighting") do |v|
    options[:terminal] = false
  end
end
parser.parse!

if file.nil? || file.empty?
  # Display help if raw command
  parser.parse! %w[--help]
end

options[:record_dir] = "tmp" if ENV["DEBUG"]

warn "Record dir: #{options[:record_dir]}" if options[:record_dir]

display = DeadEnd.call(
  source: file.read,
  filename: file.expand_path,
  terminal: options[:terminal],
  record_dir: options[:record_dir]
)

if display.document_ok?
  exit(0)
