wadlgen ======= An experiment to try to generate WADL (http://www.w3.org/Submission/wadl/) based on the routing information found in Rails 3 config/routes.rb. Approach: - Minimal rake task that calls a library to generate the WADL - Save application.wadl in public/ - Let the user edit application.wadl to add information that can't be extracted, and preserve what the user has added the next time the task is run - Needs Ruby 1.9.2 for ordered hashes in tests, also works on 1.8.7. What works: - Parse a WADL file to an object model - Generate a WADL file from an object model - Parse a Rails Route file to a object model - Rake task to parse the rails route - merge two object models - make the rails task write a public/application.wadl file - 100% code coverage by unit tests Rails 3 Usage: Add this to the Gemfile: gem 'wadlgen', :git => 'git://github.com/austvik/wadlgen.git' To generate a public/application.wadl: rake wadlgen Now you can edit public/application.wadl. The next time you run rake wadlgen, any changes to the application will be merged into your WADL file, while your changes are preserved. Programmatic usage: There are several methods that can be used to generate, merge and write wadl object structures: require 'wadlgen' # Generate a WADL XML document based on a Rails application # and base. Wadlgen::Wadl.generate(application, base) # parses a given XML string, and generates a Wadlgen::Application # object from it. Wadlgen::Wadl.parse_xml(xml_doc) # Parses routes from Rails 3, and generates a Wadlgen::Application # object from it. Wadlgen::Wadl.parse_route(application, base) # Generates a WADL XML string based on a Wadlgen::Application object Wadlgen::Wadl.generate_wadl(application) # Merges two Wadlgen::Application objects and returns the result # as another Wadlgen::Application object. Wadlgen::Wadl.merge(initial_application, additional_application) In addition the Wadlgen::* classes in src/wadlgen/classes.rb can be used to understand the object model created from these methods, or to generate structures to write to a WADL XML file.
