add_tag(name, start, stop)

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

annotate(tag)

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

end_accepting()

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

init_tags()

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

start_accepting()

Here’s the client side of the visitor pattern

[Source]

    # File rdoc/markup/simple_markup/to_html.rb, line 57
        def start_accepting
          @res = ""
          @in_list_entry = []
        end

wrap(txt, line_len = 76)

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
