Nevermind, I do. From http://www.ruby-forum.com/topic/125007
Usage:
To call the snippet:
<r:snippet name='test-snippet' title='Joe Rules'> Content is in here
</r:snippet>
The snippet:
<div>
<h2> <r:var name='title' /> </h2>
<p> Content: <r:yield /> </p>
</div>
The code:
# TODO Put into extension
desc %{ crazy hack for getting params in snippets }
tag "snippet:var" do |tag|
var = tag.attr['name'] || nil
if var.blank?
%{<b>NO ATTR SPECIFIED</b>}
else
ret_val = nil
content =
tag.context.instance_variable_get(:@tag_binding_stack).detect{ |slot|
slot.name == "snippet"}
if !content.blank?
ret_val = content.attr[var] || nil
if ret_val.blank?
%{<b>COULDN'T FIND ATTR #{var}</b>}
else
%{#{ret_val}}
end
else
%{<b>ERROR IN GETTING CONTENT</b>}
end
end
end
