Rails Lite

This is a reconstruction of the basic functionality of Rails, in six phases, developed as a test-driven project.

Phase 1: Server

Set up a simple server using the WEBrick module, along with rudimentary request/response functionality.

Phase 2: Basic Controllers

Lay the foundation of ControllerBase, which provides the functionality that ActionController::Base does in Rails: the render and redirect_to controller methods.

Phase 3: Template Rendering

Use Kernel#binding to evaluate ERB code and update the render method to handle HTML content.

Phase 4: Session Management

Store session information using WEBrick::Cookie objects and a Session class. Update controllers to store session information.

Phase 5: Query Params and Request-Body Params

Parse query string and post body to extract params at any level of nesting using Regex. Set up a Params object to store the params as a controller instance variable.

Phase 6: Routing and Route Params

Set up a Route object that stores a URL pattern, an HTTP method, a controller class, and an action name. Extract the route params from the URL using Regex.
Set up a Router object to match a requested URL with a Route object given a HTTP request.
Modify controllers to invoke the appropriate action when the Router is run.
