# YARD::I18n::Text

Provides some convenient features for translating a text.

### Public Class Methods

new(input, options={}) click to toggle source

Creates a text object that has translation related features for the input text.

@param [each_line] input a text to be translated. @option options [Boolean] :have_header (false) whether the

    input text has header or not.

    # File lib/yard/i18n/text.rb, line 11
    def initialize(input, options={})
      @input = input
      @options = options
    end

### Public Instance Methods

extract_messages() click to toggle source

Extracts translation target messages from +@input+.

@yield [:attribute, name, value, line_no] the block that

    recieves extracted an attribute in header. It may called many
    times.

@yieldparam [String] name the name of extracted attribute. @yieldparam [String] value the value of extracted attribute. @yieldparam [Integer] line_no the defined line number of extracted

    attribute.

@yield [:paragraph, text, start_line_no] the block that

    recieves extracted a paragraph in body. Paragraph is a text
    block separated by one or more empty lines. Empty line is a
    line that contains only zero or more whitespaces. It may
    called many times.

@yieldparam [String] text the text of extracted paragraph. @yieldparam [Integer] start_line_no the start line number of

    extracted paragraph.

@return [void]

    # File lib/yard/i18n/text.rb, line 34
    def extract_messages
      parse do |part|
        line_no = part[:line_no]
        case part[:type]
        when :markup, :empty_line
          # ignore
        when :attribute
          yield(:attribute, part[:name], part[:value], part[:line_no])
        when :paragraph
          yield(:paragraph, part[:paragraph], part[:line_no])
        end
      end
    end

translate(locale) click to toggle source

Translates into `locale`.

@param [Locale] locale the translation target locale. @return [String] translated text.

    # File lib/yard/i18n/text.rb, line 52
    def translate(locale)
      translated_text = ""
      parse do |part|
        case part[:type]
        when :markup
          translated_text << part[:line]
        when :attribute
          prefix = "#{part[:prefix]}#{part[:name]}#{part[:infix]}"
          value = locale.translate(part[:value])
          suffix = part[:suffix]
          translated_text << "#{prefix}#{value}#{suffix}"
        when :paragraph
          translated_text << locale.translate(part[:paragraph])
        when :empty_line
          translated_text << part[:line]
        else
          raise "should not reach here: unexpected type: #{type}"
        end
      end
      translated_text
    end
