# An ERb wrapper that allows nesting of one ERb template inside another.
|
|
#
|
|
# This TemplatePage operates similarly to RDoc 1.x's TemplatePage, but uses
|
|
# ERb instead of a custom template language.
|
|
#
|
|
# Converting from a RDoc 1.x template to an RDoc 2.x template is fairly easy.
|
|
#
|
|
# * %blah% becomes <%= values["blah"] %>
|
|
# * !INCLUDE! becomes <%= template_include %>
|
|
# * HREF:aref:name becomes <%= href values["aref"], values["name"] %>
|
|
# * IF:blah becomes <% if values["blah"] then %>
|
|
# * IFNOT:blah becomes <% unless values["blah"] then %>
|
|
# * ENDIF:blah becomes <% end %>
|
|
# * START:blah becomes <% values["blah"].each do |blah| %>
|
|
# * END:blah becomes <% end %>
|
|
#
|
|
# To make nested loops easier to convert, start by converting START statements
|
|
# to:
|
|
#
|
|
# <% values["blah"].each do |blah| $stderr.puts blah.keys %>
|
|
#
|
|
# So you can see what is being used inside which loop.
