<h1>PyPLE</h1>
- <p>PyPLE (pronounced "pipple") is the Python Persistent Logic Engine -- a framework for composing, evaluating, and storing logical expressions.</p>
+ <p>PyPLE (pronounced "pipple") is the Python Persistent Logic Engine—a framework for composing, evaluating, and storing logical expressions. With PyPLE, you can compose complex chains of simple logical operators and store them in a database. You can then apply those chains of logic to any data you like.</p>
+ <p>PyPLE now uses <a href="http://www.sqlobject.org/">SQLObject</a> for database connectivity and object-relational mapping. If you are a Python developer and don't know about SQLObject, check it out!</p>
+ <h2>Code Example</h2>
+ <div class="code">
+ <pre>
+ >>> import pyple
+ >>> import yaml # use PyYAML for loading DB connection parameters
+ >>>
+ >>> E = pyple.Engine() # instantiate a PyPLE engine
+ >>> E.connect_to_db(pyple.Engine.build_db_uri(yaml.load(open('pyple-db.yaml').read()))) # Connect to the DB
+ Connecting to DB with: mysql://pyple:pyple@localhost:3306/pyple2?debug=1
+ Connected to DB: <sqlobject.mysql.mysqlconnection.MySQLConnection instance at 0x11e5d50>
