add_tag(name, start, stop) click to toggle source

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

 
               # 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) click to toggle source

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

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

init_tags() click to toggle source

Set up the standard mapping of attributes to HTML tags

 
               # 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() click to toggle source

Here's the client side of the visitor pattern

 
               # File rdoc/markup/simple_markup/to_html.rb, line 57
def start_accepting
  @res = ""
  @in_list_entry = []
end
            
wrap(txt, line_len = 76) click to toggle source

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

 
               # 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
