Where is an appropriate place to put helper methods for tags to  
support the DRY principle?

Tags are instance\_eval’d on the page, so depending on how your page  
hierachy either put them as a method on a superclass or put them in a  
module which is included in each of the pages.

Thanks for that explanation!

I ended up creating a MyTags module that included tag definitions as  
well as helper methods. For those who may have the same question I did  
something like this:

In extensions/my\_tags/lib/my\_tags.rb:

module MyTags  
include Radiant::Taggable

def helper\_hello  
“hello”  
end

tag ‘hello’ do |tag|  
helper\_hello  
end  
end

In extensions/my\_tags/my\_tags\_extension.rb:

class MyTagsExtension \< Radiant::Extension  
version “1.0”  
description “Adds my tags to the global tag library”  
url “http://my\_tags.com”

def activate  
Page.send :include, MyTags  
end  
end

As you can see my helper method ‘helper\_hello’ is available from within  
my tags.

The above technique used to include tags in the global scope was  
suggested a few months back in this mailing list and I found it works  
out quite nicely.
