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 markup/simple_markup/to_html.rb, line 40
40:     def add_tag(name, start, stop)
41:       @attr_tags << InlineTag.new(SM::Attribute.bitmap_for(name), start, stop)
42:     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 markup/simple_markup/to_html.rb, line 50
50:     def annotate(tag)
51:       tag
52:     end

init_tags()

Set up the standard mapping of attributes to HTML tags

    # File markup/simple_markup/to_html.rb, line 28
28:     def init_tags
29:       @attr_tags = [
30:         InlineTag.new(SM::Attribute.bitmap_for(:BOLD), "<b>", "</b>"),

33:       ]
34:     end

start_accepting()

Here‘s the client side of the visitor pattern

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

wrap(txt, line_len = 76)

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

[Source]

     # File markup/simple_markup/to_html.rb, line 115
115:     def wrap(txt, line_len = 76)
116:       res = ""
117:       sp = 0
118:       ep = txt.length
119:       while sp < ep
120:         # scan back for a space
121:         p = sp + line_len - 1
122:         if p >= ep
123:           p = ep
124:         else
125:           while p > sp and txt[p] != ?\s
126:             p -= 1
127:           end
128:           if p <= sp
129:             p = sp + line_len
130:             while p < ep and txt[p] != ?\s
131:               p += 1
132:             end
133:           end
134:         end
135:         res << txt[sp...p] << "\n"
136:         sp = p
137:         sp += 1 while sp < ep and txt[sp] == ?\s
