Title Body

I've been working on my first Rails 3 plugin, to package up a simple helper function that I like having in the ApplicationHelper of all my apps. You can see the whole code on Github . Here's my first attempt: ## lib/semantic_id.rb ## require 'semantic_id/version' module ::ActionView::Helpers::TextHelper def semantic_id string = String.new case when controller.action_name =~ /new|edit/ string += controller.action_name + "_" when controller.action_name =~ /index|create/ string += controller.controller_name else string += controller.controller_name.singularize end string += "_view" end end Now, this works, but as I understand it this is not the 'Rails 3 Way' of extending ActiveSupport or any other Rails module. I haven't been able to find much documentation on how you're "supposed" to build a Rails 3 gem. I tried following the Rails Guide, but the method given there for adding helpers didn't work, or else I was missing something. My question is: given the code above as an example of the functionality I'm looking for, how would you turn this into a Rails 3 plugin Gem? Thanks!
