Let s think about eval first. I ve talked about a few basic types already, like numbers and strings, as well as symbols and conses. Numbers and strings evaluate to themselves. Since the interpreter reuses Ruby s numbers and strings, all you need to do is add a lispeval method to each. Using Ruby s monkeypatching capability, it s easy to add this method to existing classes.

But at this point, it s worth wondering if you ll be stealing other Ruby types at some point. Instead of adding lispeval to each type you might want to use, just add a default lispeval method to Object that returns self. (You can delete the lispeval methods on Numeric and String now.)

MythWeather is a plug-in that displays weather information for selected cities. At the time of writing this, MythWeather supports a whopping 38,123 locations around the world via Weather.com s online weather service. First you need to configure which location you are in and whether you want metric or imperial units for display. Then you need to configure how aggressive you want MythWeather to be. This aggressiveness setting decides how long to wait before deciding that a connection to Weather.com has timed out; the value for you will vary depending on how fast your Internet connection is. The configuration screen appears if you either go to Utilities / Setup Setup Info Center Settings Weather Settings or select Information Center Weather without having ever configured MythWeather. Figure 9-4 shows an example of the configuration screen.

Once again, our first step for creating our new application will be to install the Restful Authentication plug-in to provide us with the user login and authentication system for our application. We start by adding the plug-in to our application: ruby script/plugin install http://svn.techno-weenie.net/projects/plugins/ restful_authentication/ + ./restful_authentication/README + ./restful_authentication/Rakefile + ./restful_authentication/generators/authenticated/USAGE + ./restful_authentication/generators/authenticated/authenticated_generator.rb + ./restful_authentication/generators/authenticated/templates/activation.rhtml + ./restful_authentication/generators/authenticated/templates/ authenticated_system.rb + ./restful_authentication/generators/authenticated/templates/ authenticated_test_helper.rb + ./restful_authentication/generators/authenticated/templates/controller.rb + ./restful_authentication/generators/authenticated/templates/fixtures.yml + ./restful_authentication/generators/authenticated/templates/functional_test.rb + ./restful_authentication/generators/authenticated/templates/helper.rb + ./restful_authentication/generators/authenticated/templates/login.rhtml + ./restful_authentication/generators/authenticated/templates/migration.rb + ./restful_authentication/generators/authenticated/templates/model.rb + ./restful_authentication/generators/authenticated/templates/model_controller.rb + ./restful_authentication/generators/authenticated/templates/

The evaluation method for the Symbol class is a little more interesting. In Lisp, unquoted symbols evaluate to the value stored in the environment under their name. This is where the env parameter to the lispeval method comes in.

Figure 9-4. Configuring MythWeather When you run MythWeather from Information Center Weather, the current weather is downloaded from the Internet. This can take a little bit of time, so you will probably end up with the screen shown in Figure 9-5.

You take the environment passed into the lispeval method and look up the symbol that is being evaluated in it. This will return the value stored in the environment, if such a value exists; otherwise, it will throw an error. Let s play around with this in Ruby.
