Kamaelia is a project that aims to allow the BBC and others to create and test open protocols for large scale streaming. Substantial subsystems include a core concurrency subsystem and the beginnings of an RTSP/RTP streaming server. Existing functionality includes a complete single threaded, coroutine-based concurrency framework (Axon), a generic TCP client and server framework that allows protocols to be trivially created, a number of example protocols, and an Ogg Vorbis decoding subsystem for client site testing (libvorbissimple).
Karaoke con SMIL is a project to synchronize audio, text, and images and export the final result to SMIL, which can be played in multimedia players such as Real Player, Helix Player, Ambulant Player, etc. on several devices (computers, mobile phones, PDAs, etc.). In short, this application synchronizes the multimedia elements in a way similar to karaoke.
Kiwi is an object-oriented framework for developing graphical applications using Python. It has a set of classes that provide a solid application architecture, and a set of high level graphical components that can be used as drop-in replacements for some of the widgets in PyGTK, including CList, CTree, Label, OptionMenu, and more. It includes a complete developer's manual, with examples and screenshots, and full API documentation.
LEPL is a recursive descent parser library written in Python. It is based on parser combinator libraries popular in functional programming, but also exploits Python language features. Operators provide a friendly syntax, and the consistent use of generators supports full backtracking and resource management. Backtracking implies that a wide variety of grammars are supported; appropriate memoisation ensures that even left-recursive grammars terminate.
Langer is an object oriented, rule based programming language. Its interpreter is shipped as a Python library. It was created to express behavior strategies, has a simple syntax based on languages like Python and C, and was designed to be convenient and readable for a programmer, but it can be easily used in genetic programming as well.
LanguageSys is meant to internationalize your applications. It handles the access to language files, which are based on an INI style. It is possible to precompile the language files to increase the speed of processing. This system is focused on being highly object-oriented, so it makes the language aliases aviable as member variables of the own class. It contains a system to fetch a list of all the available languages by a given directory where the language files are located. A distinction of languages is drawn as RFC1766 recommends. Examples, documentation, and a simple script to precompile your language files are included.
Lazy Evaluation for Python is a package which implements lazy evaluation for Python. It does so by implementing proxy objects that will automatically force valuation when some magic methods are called, and it will automatically further delay evaluation on other methods (attribute access, item access, and calling).
