Schematra is currently an early exploration project created for learning purposes, but hopefully it will grow into something more useful over time. Why Schematra?

Once you have it installed, you can install schematra as an egg: git clone https://github.com/rolandoam/schematra cd schematra chicken-install That will download the dependencies and install the core modules so that they're available system-wide. Quick Start Here's a simple "Hello World" application: (import schematra) ; ; Define routes (get " / " ( lambda ( req params ) "Hello, World!")) (get " /users/:id " ( lambda ( req params ) ( let ((user-id (alist-ref " id " params equal?))) (format " User ID: ~A " user-id)))) (post " /submit " ( l...
