class RubyBBCode::Templates::HtmlTemplate
This class is designed to help us build up the HTML data. It starts out as a template such as…
@opening_part = '<a href="%url%">%between%' @closing_part = '</a>'
and then slowly turns into…
@opening_part = '<a href="http://www.blah.com">cool beans' @closing_part = '</a>'
Attributes
