Add a new set of HTML tags for an attribute. We allow separate start and end tags for flexibility

[Source]

# File rdoc/markup/simple_markup/to_html.rb, line 40
    def add_tag(name, start, stop)
      @attr_tags << InlineTag.new(SM::Attribute.bitmap_for(name), start, stop)
    end

Given an HTML tag, decorate it with class information and the like if required. This is a no-op in the base class, but is overridden in HTML output classes that implement style sheets

[Source]

# File rdoc/markup/simple_markup/to_html.rb, line 50
    def annotate(tag)
      tag
    end

# File rdoc/markup/simple_markup/to_html.rb, line 62
    def end_accepting
      @res
    end

Set up the standard mapping of attributes to HTML tags

[Source]

# File rdoc/markup/simple_markup/to_html.rb, line 28
    def init_tags
      @attr_tags = [
        InlineTag.new(SM::Attribute.bitmap_for(:BOLD), "<b>", "</b>"),
        InlineTag.new(SM::Attribute.bitmap_for(:TT),   "<tt>", "</tt>"),
        InlineTag.new(SM::Attribute.bitmap_for(:EM),   "<em>", "</em>"),
      ]
    end

Here’s the client side of the visitor pattern

    def start_accepting
      @res = ""
      @in_list_entry = []
    end

This is a higher speed (if messier) version of wrap

[Source]

# File rdoc/markup/simple_markup/to_html.rb, line 115
    def wrap(txt, line_len = 76)
      res = ""
      sp = 0
      ep = txt.length
      while sp < ep
        # scan back for a space
        p = sp + line_len - 1
        if p >= ep
          p = ep
        else
          while p > sp and txt[p] != ?\s
            p -= 1
          end
          if p <= sp
            p = sp + line_len
            while p < ep and txt[p] != ?\s
              p += 1
            end
          end
        end
        res << txt[sp...p] << "\n"
        sp = p
        sp += 1 while sp < ep and txt[sp] == ?\s
      end
      res
    end
