cgi_buffer is a group of libraries that may be used to improve performance of CGI scripts (and other content generation engines) in some circumstances by applying performance-enhancing HTTP mechanisms that are typically not supported by them. Currently, Perl, Python, and PHP4 are supported. The Python library may also be used as a wrapper around another CGI script.
PyStem is a fast Python module with the the Porter stemming algorithm (a process for removing the commoner morphological and inflexional endings from words in English; its main use is as part of a term normalisation process that is usually done when setting up Information Retrieval systems).
Albatross is a small and flexible toolkit for developing highly stateful Web applications. It provides browser-based sessions via automatically-generated hidden form fields, server side sessions via a session server or file-based session store, a powerful and extensible templating system which promotes separation of presentation and implementation for improved program maintainability, implicit handling for pagination of sequences and tree browsing, template macros to allow repeated HTML and special effects HTML to be defined in one location, and lookup tables to translate Python values to arbitrary template code. Applications can be deployed as either CGI programs or as mod_python module with minor changes to program mainline. Custom deployment can be achieved by developing your own Request class.
Python Service Objects is a package that simplifies development of HTTP handlers. With its built-in session handling and its bridging system, it allows you to write one handler that will run with mod_python, NASAPY, CGI, etc. It offers an easy interface to HTTP info. It includes a simple, fast, robust, powerful, and extensible OO template parser.
Hep Message Server is software that transfers messages between different messaging systems. Eventually, it should transparently route messages between email, weblogs, and instant messaging. Currently Hep does one thing: fetches news feeds from Web sites and lets you view them in your email client.
ClearSilver is a high-performance, powerful, and language-neutral HTML template system. It enforces a separation between presentation code and application logic which makes writing, debugging, and maintaining Web pages easier. It can be used from C/C++, Python, Perl, Java, and Ruby. It runs on Windows and Unix.
Pysite is a tool written in Python to generate Web sites based on the contents of files in a given directory tree. It crawls through a specified directory tree looking for files matching certain configurable patterns (like intro, title-fr, and this-is-another-page-body), building up an output Web page for each set of files found. It features valid XHTML output, support for multiple language output, simple hierarchical templates (just put a template in a directory and it will be used for all subdirectories), and basic plaintext to XHTML conversion.
