topfunky/calendar_helper — pull request #14 by eric1234 (2012-02-27 23:20:59+00:00)
Title: Support for Rails 3. Key aspects here are:

* Railtie defined with Helper mixed in. This allows the gem to be added
as a dependency and nothing more and does not rely on the old init.rb
behavior of plugins.
* html_safe called if defined so the calendar isn't escaped.

I have not really tested this in an older Rails app but it should allow the
plugin to operate as before if the Railtie infrastructure or the html_safe
infastructure is not available.
