Bottle 0.5.4

Bottle 0.5.4 provides you with a quick and simple WSGI-framework which is designed for the Python Programming Language. It offers request dispatching with url parameter support (routes), templates, key/value databases, a build-in HTTP server and adapters for many third party WSGI/HTTP-server and template engines. All in a single file and with no dependencies other than the Python Standard Library.

Major Features:

1. Request dispatching: Map requests to handler-callable using URL-routes:
   • URL parameters: Use regular expressions /object/(?P[0-9]+) or simplified syntax /object/:id to extract data out of URLs
2. WSGI abstraction: Don't worry about cgi and wsgi internals:
   • Input: request.GET['parameter'] or request.POST['form-field']
   • HTTP header: response.header['Content-Type'] = 'text/html'
   • Cookie Management: response.COOKIES['session'] = 'new_key'
   • Static files: send_file('movie.flv', '/downloads/') with automatic mime-type guessing
   • Errors: Throw HTTP errors using abort(404, 'Not here') or subclass HTTP Error and use custom error handlers
3. Databases: Build in persistent key/value databases with fast memory caching:
   • Use db.db_name.key_name or db[db_name][key_name] to access stored values. Missing databases are created on demand. Missing keys raise Key Error.
   • Values are automatically pickled and saved at the end of the request live cycle.
4. Templates: Integrated template language:
   • Plain simple: Execute python code with %... or use the inline syntax {{...}} for one-line expressions
   • No Indentation Errors: You don’t have to worry about indention. Blocks are closed by %end.
   • Extremely fast: Parses and renders templates 5 to 10 times faster than mako
   • Optional support for Mako-Templates (requires mako)
5. HTTP Server: Build in WSGI/HTTP Gateway server (for development and production mode)
   • Currently supports wsgiref.simple_server (default), cherrypy, flup, paste and fapws3
6. Speed optimizations:
   • Sendfile: Support for platform-specific high-performance file-transmission facilities, such as the Unix sendfile(). Depends on wsgi.file_wrapper provided by your WSGI-Server implementation.
   • Self optimizing routes: Frequently used routes are tested first (optional)
   • Fast static routes (single dict lookup)
