The Q Equational Programming Language

The Q Equational Programming Language is a project that is being worked on by Albert Gräf at the University of Mainz in Germany. The Q language has the following properties:

• It is an interpreted language.
• The programs consist of collections of equations.
• It has dynamic object-oriented typing.
• It features exception handling and posix multi-threading.
• It comes with its own standard library.
• It can be extended with C language primitives.
• It runs on a wide variety of operating system platforms.
• An EMACS editor interface is included.
• Performance is similar to that of other interpreted languages.
• It has been released under the GNU General Public License (GPL).

The Q language Documentation explains the language in more detail. An example Huffman encoding program shows the language in use.

Version 4.3 of the Q interpreter has been released, see the NEWS document for the language change history.

Recent additions to the language include new versions of Q-Audio 1.0 and Q-Midi 1.10. Q-Audio adds a language interface to the libsndfile audio libraries, and Q-Midi adds a MIDI interface to the language.

Using combinatorial functions in the itertools module

David Mertz discusses combinational iterators in Python on IBM's developerWorks. "Python 2.2 introduced simple generators to the Python language and reconceived standard loops in terms of underlying iterators. With Python 2.3, generators become standard (no need for _future_), and the new module itertools is introduced to work flexibly with iterators. The itertools module is essentially a set of combinatorial higher-order functions, but ones that work with lazy iterators rather than with finite lists. In this installment, David explores the new module, and gives you a sense of the new expressive power available with combinatorial iterators."

XML Data Bindings in Python

Uche Ogbuji writes about XML data binding in Python on O'Reilly. "The XML community of late there has been a lot of talk that there are no really easy and efficient ways of general XML programming. Push processing has the usual rap of being too difficult. It is easy to dismiss this as a problem for amateur programmers who have not properly learned how to code state machines; but let's face it, state machines are hard to code by hand, and the community has been slow to develop more declarative and friendly tools for developing SAX processing stubs, such as LEX and YACC tools for generating parser state machines."

This article proposes some ways of shorten stylesheets without loss of functionality, and throws a glance at XSLT 2.0 user defined functions."
