About:

Language detection for various languages such as English and Dutch. This
command reads input from STDIN. Output can be a language code as plain text,
a KAF document containing the input text and language code, or a list of
probabilities.

Example:

cat some_file.kaf | language-identifier
      EOF

      separator "\nOptions:\n"

      on :v, :version, 'Shows the current version' do
        abort "language-identifier v#{VERSION} on #{RUBY_DESCRIPTION}"
      end

      on :'no-kaf', 'Disables KAF output'

      run do |opts, args|
        enable_kaf   = true

        if opts[:'no-kaf']
          enable_kaf = false
        end

        identifier = LanguageIdentifier.new(
          args:  args,
          kaf:   enable_kaf,
          probs: false,
        )

        params = JSON.parse(ENV['PARAMS']).transform_keys!(&:to_sym) rescue {}
        input  = STDIN.tty? ? nil : STDIN.read
        output = identifier.run input, params
        puts output
      end
    end
