ANN: BOTEC 0.3 -- An astrophysical and orbital mechanics calculator
by Erik Max Francis 16 Jan '05

16 Jan '05

Summary BOTEC is a simple astrophysical and orbital mechanics calculator, including a database of all named Solar System objects. Overview BOTEC is intended as a simple but useful calculator to assist with making astrophysical, orbital mechanics, and space navigation calculations. As the origin of the acronym applies, BOTEC is more of a "back-of-the-envelope calculator" rather than an industrial-strength calculator, although this may change in the future. BOTEC is primarily intended for people familiar with physics and Python, and as such is unlikely to be useful to the average enduser. BOTEC really consists of two parts: The BOTEC software, which knows what to do with the data, and the Solar System data itself, which is represented in a large data file (a Python pickle, actually). This is deliberately modularized so that the Solar System data BOTEC uses can be updated independently of thet software, and also that alternative data files (*e.g.*, hypothetical stellar systems for fictional purposes) can be supported. All values are strictly in SI units. Getting the software The current version of botec is 0.3. The latest version of the software is available in a tarball here: http://www.alcyone.com/software/botec/botec-latest.tar.gz. The official URL for this Web site is http://www.alcyone.com/software/botec/. Requirements BOTEC requires Python 2.3 or greater. In its present state, BOTEC will also not be of much use to endusers not familiar with Python, or people without some basic working knowledge of physics, astrophysics, orbital mechanics, and space navigation.

ANN: cElementTree 0.9.2 (january 15, 2005)
by Fredrik Lundh 15 Jan '05

15 Jan '05

effbot.org proudly presents the cElementTree library, a fast and very efficient implementation of the ElementTree API, for Python 2.1 and later. On typical documents, it's 15-20 times faster than the Python version of ElementTree, and uses 2-5 times less memory. The 0.9.2 release is 10-20% faster than 0.8 on my benchmarks, and uses 5-15% less memory. Here are some benchmark results, using a number of popular XML tool- kits to parse a 3405k source file on my development machine: library memory time ------------------------------------------------------------ minidom (python 2.1) 80000k 6.5s minidom (python 2.4) 53000k 1.4s ElementTree 1.3 14500k 1.1s cElementTree 0.8 5700k 0.058s cElementTree 0.9 4900k 0.047s ------------------------------------------------------------ readlines (read as utf-8) 8850k 0.093s readlines (read as ascii) 5050k 0.032s ------------------------------------------------------------ For more information on this library, including download instructions, comparisions to other popular XML toolkits, and more, see: http://effbot.org/zone/celementtree.htm enjoy /F

Collaborate at PyCon
by Jim Fulton 14 Jan '05

14 Jan '05

PyCon is not just a conference to hear people present on Python and Python applications. It's also a place to meet and work with colleagues from around the world. Consider the following opportunities for collaboration: - Sprinting A sprint is a multi-day session of intense development organized around extreme programming (XP) ideas such as pair programming. There will be four days, March 19-22, before the regular conference to sprint on a variety of projects. To see what sprints are planned, see: http://www.python.org/moin/PyConDC2005/Sprints If you would like to lead a sprint, feel free to add the sprint to that page. If you want to participate in a sprint, visit a sprint-topic page and add your name to the list of attendees so that we know how many people are coming. If you have a question about the sprints, feel free to drop me a line. - Open Space Open space is a part of PyCon designed to provide opportunities for collaboration. There are two kinds of open space at Pycon, quiet and noisy. There will be a quiet room provided throughout the conference for people to access the network and to quietly hack with others (e.g. pair program). There will also be noisy rooms for people to have discussions or give informal presentations. The noisy rooms will host up to two presentations or discussions at a time. We'll provide the opportunity to sign up for 30-minute time slots. We'll allow sign up for half of the time slots before the conference. There will be a posted schedule with spaces to sign up for the remainder of the time slots during the conference. I'll provide more information on the open space schedule soon, after we finalize the rest of the conference schedule. Jim -- Jim Fulton mailto:jim@zope.com Python Powered!

ANN: PyLinda 0.4
by Andrew Wilkinson 14 Jan '05

14 Jan '05

PyLinda 0.4 By Andrew Wilkinson <aw at cs dot york dot ac dot uk> Introduction --------------- Linda is an widely studied distributed computing environment, centred around the notion of a tuple space. A tuple space is a bag (also called a multi-set) of tuples. A tuple is an ordered, typed chunk of data. Tuple spaces exist independently of processes in the system, and the data placed into a tuple space also exist independently. See "Generative communication in Linda" (1985) and "Multiple tuple spaces in Linda" both by David Gelernter for more information on Linda. PyLinda is a simple implementation of a linda system, however it also includes several of the more recently proposed extensions to Linda in the form of multiple tuple spaces, garbage collection, sane non-blocking primitives and bulk tuple operations. Full details can be found at the website http://www-users.cs.york.ac.uk/~aw/pylinda The package can be downloaded from http://www-users.cs.york.ac.uk/~aw/pylinda/linda-0.4.tar.gz Changes In This Version --------------- - New Features * Removed SysV shared memory and made Unix Domain Sockets the default as they are quicker. * A new flashy website - Bug Fixes * Fix bug where some sockets would not be in blocking mode and hence cause an exception. Thanks to Dave St.Germain for the bug report. * Fix bug where Windows didn't define MSG_DONTWAIT in the socket module. Thanks to Dr Andrew Perella for the bug report. * Fix bug that prevented a network of servers from being formed. Thanks to Igor Chaves Cananea for the bug report and patch.

Roundup Issue Tracker release 0.8 beta 2
by Richard Jones 13 Jan '05

13 Jan '05

I'm proud to release this 8th major feature release of Roundup. This is currently a DEVELOPMENT release, meaning it probably has bugs. If you want a STABLE release, use 0.7.x First up, big thanks go to alexander smishlajev who has done some really good work getting the i18n and new configuration components of this release going. Version 0.8 introduces far too many features to list here so I've put together a What's New page: http://roundup.sourceforge.net/doc-0.8/whatsnew-0.8.html This is a bugfix release, fixing: - note about how to run roundup demo in Windows (sf bug 1082090) - fix API for templating utils extensions - remove "utils" arg (sf bug 1081981) - back_sqlite.py is missing "import time" (sf bug 1081959) - fix (list) popup (sf bug 1083570) - fix some security assertions (sf bug 1085481) - 'roundup-server -S' always writes [trackers] section heading (sf bug 1088878) - fix port number as int in mysql connection info (sf bug 1082530) - fix setup.py to work with <Python2.3 (sf bug 1082801) - fix permissions checks in cgi templating (sf bug 1082755) - fix "Users may only edit their issues" example in docs - handle ~/.my.cnf files for MySQL defaults (sf bug 1096031) If you're upgrading from an older version of Roundup you *must* follow the "Software Upgrade" guidelines given in the maintenance documentation. Roundup requires python 2.1.3 or later for correct operation. To give Roundup a try, just download (see below), unpack and run:: python demo.py Source and documentation is available at the website: http://roundup.sourceforge.net/ Release Info (via download page): http://sourceforge.net/projects/roundup Mailing lists - the place to ask questions: http://sourceforge.net/mail/?group_id=31577 About Roundup ============= Roundup is a simple-to-use and -install issue-tracking system with command-line, web and e-mail interfaces. It is based on the winning design from Ka-Ping Yee in the Software Carpentry "Track" design competition. Note: Ping is not responsible for this project. The contact for this project is richard(a)users.sourceforge.net. Roundup manages a number of issues (with flexible properties such as "description", "priority", and so on) and provides the ability to: (a) submit new issues, (b) find and edit existing issues, and (c) discuss issues with other participants. The system will facilitate communication among the participants by managing discussions and notifying interested parties when issues are edited. One of the major design goals for Roundup that it be simple to get going. Roundup is therefore usable "out of the box" with any python 2.1+ installation. It doesn't even need to be "installed" to be operational, though a disutils-based install script is provided. It comes with two issue tracker templates (a classic bug/feature tracker and a minimal skeleton) and five database back-ends (anydbm, sqlite, metakit, mysql and postgresql).

ANN: Amara XML Toolkit 0.9.2
by Uche Ogbuji 13 Jan '05

13 Jan '05

http://uche.ogbuji.net/tech/4Suite/amara ftp://ftp.4suite.org/pub/Amara/ Changes in this release: * Use local names rather than QNames for default bindings * Add attribute support to XPath * Add amara.binderytools.preserve_attribute_details rule * Reorg and fix demos and tests * Add Flextyper DTLL implementation * Add parsing functions binderytools.bind_string, binderytools.bind_stream * Add binderytools.pushbind. This one deserves some elaboration. The following is complete code for iterating through address labels in an XML document, while never loading more memory than needed to hold one label element: from amara import binderytools for subtree in binderytools.pushbind('/labels/label', source='labels.xml'): print subtree.label.name, 'of', subtree.label.address.city Amara XML Toolkit is a collection of Python tools for XML processing-- not just tools that happen to be written in Python, but tools built from the ground up to use Python idioms and take advantage of the many advantages of Python. Amara builds on 4Suite [http://4Suite.org], but whereas 4Suite focuses more on literal implementation of XML standards in Python, Amara focuses on Pythonic idiom. It provides tools you can trust to conform with XML standards without losing the familiar Python feel. The components of Amara are: * Bindery: data binding tool (fancy way of saying: a very Pythonic XML API) * Scimitar: implementation of the ISO Schematron schema language for XML; converts Schematron files to Python scripts * domtools: set of tools to augment Python DOMs * saxtools: set of tools to make SAX easier to use in Python * Flextyper: user-defined datatypes in Python for XML processing There's a lot in Amara, but here are highlights: Amara Bindery: XML as easy as py -------------------------------- Based on the retired project Anobind, but updated to use SAX rather than DOM to create bindings. Bindery reads an XML document and returns a data structure of Python objects corresponding to the vocabulary used in the XML document, for maximum clarity. Bindery turns the document <monty> <python spam="eggs">What do you mean "bleh"</python> <python ministry="abuse">But I was looking for argument</python> </monty> Into a set of objects such that you can write binding.monty.python.spam In order to get the value "eggs" or binding.monty.python[1] In order to get the value "But I was looking for argument". There are other such tools for Python, and what makes Anobind unique is that it's driven by a very declarative rules-based system for binding XML to the Python data. You can register rules that are triggered by XPattern expressions specialized binding behavior. It includes XPath support and supports mutation. Bindery is very efficient, using SAX to generate bindings. Scimitar: exceptional schema language for an exceptional programming language ----------------------------------------------------------------------------- Merged in from a separate project, Scimitar is an implementation of ISO Schematron that compiles a Schematron schema into a Python validator script. You typically use scimitar in two phases. Say you have a schematron schema schema1.stron and you want to validate multiple XML files against it, instance1.xml, instance2.xml, instance3.xml. First you run schema1.stron through the scimitar compiler script, scimitar.py: scimitar.py schema1.stron A file, schema1.py is generated and can be used to validate XML instances: python schema1.py instance1.xml Which emits a validation report. Amara DOM Tools: giving DOM a more Pythonic face ------------------------------------------------ DOM came from the Java world, hardly the most Pythonic API possible. Some DOM-like implementations such as 4Suite's Domlettes mix in some Pythonic idiom. Amara DOM Tools goes even further. Amara DOM Tools feature pushdom, similar to xml.dom.pulldom, but easier to use. It also includes Python generator-based tools for DOM processing, and a function to return an XPath location for any DOM node. Amara SAX Tools: SAX without the brain explosion ------------------------------------------------ Tenorsax (amara.saxtools.tenorsax) is a framework for "linerarizing" SAX logic so that it flows more naturally, and needs a lot less state machine wizardry. License ------- Amara is open source, provided under the 4Suite variant of the Apache license. See the file COPYING for details. Installation ------------ Amara requires Python 2.3 or more recent and 4Suite 1.0a3 or more recent. Make sure these are installed, unpack Amara to a convenient location and run python setup.py install -- Uche Ogbuji Fourthought, Inc. http://uche.ogbuji.net http://4Suite.org http://fourthought.com Use CSS to display XML - http://www.ibm.com/developerworks/edu/x-dw-x-xmlcss-i.html Full XML Indexes with Gnosis - http://www.xml.com/pub/a/2004/12/08/py-xml.html Be humble, not imperial (in design) - http://www.adtmag.com/article.asp?id=10286 UBL 1.0 - http://www-106.ibm.com/developerworks/xml/library/x-think28.html Use Universal Feed Parser to tame RSS - http://www.ibm.com/developerworks/xml/library/x-tipufp.html Default and error handling in XSLT lookup tables - http://www.ibm.com/developerworks/xml/library/x-tiplook.html A survey of XML standards - http://www-106.ibm.com/developerworks/xml/library/x-stand4/ The State of Python-XML in 2004 - http://www.xml.com/pub/a/2004/10/13/py-xml.html

[ANNOUNCE] Twenty-first release of PythonCAD now available
by Art Haas 12 Jan '05

12 Jan '05

I'm pleased to announce the twenty-first development release of PythonCAD, a CAD package for open-source software users. As the name implies, PythonCAD is written entirely in Python. The goal of this project is to create a fully scriptable drafting program that will match and eventually exceed features found in commercial CAD software. PythonCAD is released under the GNU Public License (GPL). PythonCAD requires Python 2.2 or newer. The interface is GTK 2.0 based, and uses the PyGTK module for interfacing to GTK. The design of PythonCAD is built around the idea of separating the interface from the back end as much as possible. By doing this, it is hoped that both GNOME and KDE interfaces can be added to PythonCAD through usage of the appropriate Python module. Addition of other PythonCAD interfaces will depend on the availability of a Python module for that particular interface and developer interest and action. The twenty-first release of PythonCAD adds the ability to save the visibility and locked status of entities when saving a drawing. This release also includes improved code for handling the undo/redo operations by simplifying various routines as well as making similiar routines in various modules consistent. Like all previous releases, numerous bug fixes and code improvements have been applied. A mailing list for the development and use of PythonCAD is available. Visit the following page for information about subscribing and viewing the mailing list archive: http://mail.python.org/mailman/listinfo/pythoncad Visit the PythonCAD web site for more information about what PythonCAD does and aims to be: http://www.pythoncad.org/ Come and join me in developing PythonCAD into a world class drafting program! Art Haas -- Man once surrendering his reason, has no remaining guard against absurdities the most monstrous, and like a ship without rudder, is the sport of every wind. -Thomas Jefferson to James Smith, 1822

[Ann] Voidspace Pythonutils Website Change and Updates
by Michael Foord 12 Jan '05

12 Jan '05

The Voidspace Pythonutil Pages have had a long overdue overhaul. The url of the Voidspace Pythonutils homepage has changed. It is now : http://www.voidspace.org.uk/python/index.html There are now separate pages for programs, modules, recipes, and CGIs. Several of the bigger modules and programs have their own pages. The following modules have also been updated : StandOut Version 2.1.0 6th Jan 2005 http://www.voidspace.org.uk/python/modules.shtml#standout This simple 'Flexible Output Object' has now been updated to work with sys.stderr as well as sys.stdout. It can log them separately or to the same file. StandOut is a simple way of adding 'variable verbosity levels' to your program *and* logging, just using normal print commands. guestbook.py http://www.voidspace.org.uk/python/cgi.shtml#guestbook Version 1.2.0 3rd December 2004 The Voidspace Python Guestbook has been updated. You can now use sendmail instead of smtplib as an option (my current host will only allow sendmail). License change (again!) - now the BSD license. Changed to use the UTF-8 encoding throughout. We ought to be able to accept 'foreign' (non-ascii) entries now. ConfigObj Version 3.2.3 2nd December 2004 Fixes a critical bug and a couple of minor improvements. ConfigObj is for simple but powerful config file parsing/creation. Fixed bug in creating non-flatfiles from scratch. (__comments__ KeyError). (critical bugfix) Tuple entries are written out as lists rather than being converted to strings. When an exception is raised, it's no longer printed first. Added the istrue method. Changed the license to BSD-License. As far as I know these are the only substantial changes to modules. A few others have had *minor* bugfix updates as well.

[Ann] PyName and downman
by Fuzzyman 12 Jan '05

12 Jan '05

A couple of new 'modules' available from Voidspace Pythonutils. PyName http://www.voidspace.org.uk/python/modules.shtml#pyname Slightly tongue in cheek, this isn't really a python module. It's three lists of English words containing 'py' - intended to be helpful to those choosing names for python projects. The word lists were produced from an initial file of about 8mb. Words selected all contain 'py', single words or hyphenated words, but no compound words. * pywordlist.txt All words contain 'py' 23kb - 1946 words * pywordlist2.txt All words starting or ending in 'py' 16kb - 1406 words * pywordlist3.txt All words as pywordlist2, but only words less than 10 chars long 5kb - 658 words. downman.py Version 0.2.1 14th December 2004 Simple Download Manager http://www.voidspace.org.uk/python/cgi.shtml#downman This is a simple download manager tool. It may be egotistical, but I like to know which of my projects are being downloaded (and which aren't). Simply make your files available in a single directory and have the links point to downman (see the download link for downman itself for an example) and downman will track the downloads. At the moment it only presents simple data - but all the raw data is collected to do per week/last month (or whatever) analysis. It will also manage links as well. See the example output at http://www.voidspace.org.uk/cgi-bin/voidspace/downman.py Regards, Fuzzyman http://www.voidspace.org.uk/python/index.shtml

PyCrypto 2.0, pysco 1.4 - Windows Binaries for 2.4
by Fuzzyman 12 Jan '05

12 Jan '05

The location of the prebuilt windows installer for PyCypto 2.0 (for python 2.4) has changed. Apologies for any confusion, this is because of a website reorganisation at Voidspace. The new location is : http://www.voidspace.org.uk/python/modules.shtml#pycrypto There is also a prebuilt windows installer for psyco 1.4 (for python 2.4). This is because there isn't yet a prebuilt binary available from sourceforge. http://www.voidspace.org.uk/python/modules.shtml#psyco Both built using the free, Microsoft, optimizing compiler. Following instructions from : http://www.vrplumber.com/programming/mstoolkit/index.html Regards, Fuzzy http://www.voidspace.org.uk/python/index.shtml

ANN: Paranoia 1.3 released (OO rewrite)
by Sean P. Kane 12 Jan '05

12 Jan '05

Paranoia 1.3 has been released! What is it? ======== Paranoia 1.3 is a port to Python from C of the old "paranoia" console game that used to be distributed with the bsd-games package, but has long since been removed. I ported this from C to Python as an exercise in learning Python and because I was suffering a serious bout of boredom and nostalgia. Paranoia is based on the role playing game, by the same name, that was very popular amoung a certain set during the 1980's and is making a resurgance today. Note that this release is as identical to the oringal game as I could make it within reason. I'm not a C coder, so I may have missed some functionality, but I don't think so. If you notice any errors or have any suggestions on cleaning up the Python code, please feel free to contact me. Where can I get it? ============== paranoia.py and the original c code that it is based on are currently avaliable from: http://homepage.mac.com/spkane/python/ # HISTORY # ======= # # 1.3 - 11 Jan 2005 # + Massive Object Oriented re-working done by: Steven Bethard # + A few nice changes from Scott David Daniels # # 1.2.1 - 10 Jan 2005 # + Greatly improved next_page method based on code from Andy Gimblett - http://www.cs.swan.ac.uk/~csandy/ # # 1.2 - 03 Jan 2005 # + Initially started porting application Trust no one!

by Fredrik Lundh 11 Jan '05

11 Jan '05

effbot.org proudly presents the cElementTree library, a fast and very efficient implementation of the ElementTree API, for Python 2.1 and later. On typical documents, it's 15-20 times faster than the Python version of ElementTree, and uses 2-5 times less memory. Here are some benchmark figures, using a number of popular XML tool- kits to parse a 3405k document-style XML file from disk. library memory time ------------------------------------------------------------ minidom (python 2.1) 80000k 6.5s minidom (python 2.4) 53000k 1.4s ElementTree 1.3 14500k 1.1s pyRXPU 11500k 0.22s cElementTree 0.8 5700k 0.058s ------------------------------------------------------------ readlines (read as text) 5050k 0.032s ------------------------------------------------------------ The library is available as C source code, and as Windows installers for all recent Python versions. Get your copy here: http://effbot.org/downloads#celementtree The cElementTree module uses some support functions from the standard ElementTree library, and will not work properly without it. If you haven't installed it already, you can get it from: http://effbot.org/downloads#elementtree enjoy /F

ANN: PyComicsViewer-0.7 released
by ionutz 11 Jan '05

11 Jan '05

PyComicsViewer-0.7 has been released What is PyComicsViewer? ======================= Is a comics viewer written in python, PyGTK and PIL. I made it as I didn't fully like any of the existing viewers and I wanted something that works the same (nice) way on both Linux and Windows. Because of the way it was implemented, you can also use it like a kind of image browser/viewer, but this is not its primary destination. Browsing images from uncompressed directories is provided because resulted naturally from the implementation and because I've seen some people that distribute their scaned comics uncompressed. What's new in version 0.7? ========================== This is the first public release of the viewer. 90% of the functionality is already in place. Some things need better implementation and some are still to be implemented. However, you should be able to read cbr and cbz files with it. Licensing ========= PyComicsViewer is released under the GPL. Where can I get it? =================== You can download it from: http://borco.net/html/PyComicsViewer/ Cheers, Ionutz

ANN: Kamaelia's Axon-1.0.2 For Series60 Released.
by Michael Sparks 10 Jan '05

10 Jan '05

Axon-1.0.2 For Series60 has been released! This is a modified version of Axon 1.0.2 working (with limited testing - the normal test suite passes) on the Nokia series 60 mobile phones. The key differences are: * The debug subsystem has been disabled * The directory structure has been flattened. What is Axon? ============= Axon is a collection of pure python modules from the Kamaelia project which allow you to build concurrent systems in a compositional manner using communicating python generators. Components are python generators are augmented by inbox and outbox queues (lists) for communication in a CSP like fashion. Put another way this allows you to build complex systems out of small concurrent components in a fashion similar to unix pipelines, except rather than being limited to just stdin/stdout you can have whatever inputs/outputs you desire. (The defaults are inbox/outbox, control/signal) Axon should be relatively feature complete and the API stable, given its design has been fleshed by use in the Kamaelia project. Given Kamaelia components for building network servers, pygame wrappers & vorbis playback have been written using Axon so far, we expect that Axon should be useful for other areas where multiple activities need to be handled within a single thread, whilst allowing the code to remain looking more or less single threaded. Documentation is generated directly from the test suite output. What's new in version 1.0.2-series60? ===================================== * Initial release for series 60 * API documentation has been added (though a work in progress!) * Examples from docs have been fully tested * Changes in distribution structure to simplify transferring onto Nokia mobiles. Licensing ========= Kamaelia is released under the Mozilla trilicense scheme (MPL/GPL/LGPL). Specifically you may choose to accept either the Mozilla Public License 1.1, the GNU General Public License 2.0 or the Lesser General Public License 2.1. Proprietary licensing details available upon request. Where can I get it? =================== Axon is a sub-project of the BBC R&D Kamaelia project, which means Axon is downloadable from http://sourceforge.net/projects/kamaelia/ Web pages are here: http://kamaelia.sourceforge.net/Docs/Axon.html http://kamaelia.sourceforge.net/ (includes info on mailing lists) ViewCVS access is available here: http://cvs.sourceforge.net/viewcvs.py/kamaelia/ Best Regards, Michael. -- Michael.Sparks(a)rd.bbc.co.uk British Broadcasting Corporation, Research and Development Kingswood Warren, Surrey KT20 6NP This message (and any attachments) may contain personal views which are not the views of the BBC unless specifically stated.

Chicago Python Users Group: Thu 13 Jan Meeting
by Ian Bicking 10 Jan '05

10 Jan '05

The Chicago Python User Group, ChiPy, will have its next meeting on Thursday, 13 January 2005, starting at 7pm. For more information on ChiPy see http://chipy.org This month the topic will be An Introduction To Jython, presented by Brian Zimmer. Jython is an implementation of Python that runs on the Java Virtual Machine. Brian Zimmer has been using and developing Jython for over 4 years. He is the author of zxJDBC, the Python DB API implementation for Jython as well as recently taking over primary maintenance for the Jython project. Brian recently receive a grant from the Python Software Foundation for his project "Moving Jython Forward." There will also be time to chat, and many opportunities to ask questions. We encourage people at all levels to attend. Location -------- This month we will be meeting in the Monadnock Building Conference Room 826, 53 W Jackson St, in downtown Chicago. This is immediately adjacent to the blue line and an easy walk from all Metra stations and the CTA red line, at the corner of Jackson and Dearborn. Because the meeting is held after-hours for the building, we need to provide a list of attendees. Please send your name (as it appears on your ID) to tobis (at) mailbag dot com (if you aren't sure you'll be able to come, send your name anyway). If you drive, aim for the Congress Parkway exit from the Ryan (I-90/94) or the east end of the Eisenhower (I-290). About 5 blocks east and 2 blocks north once you enter the street grid is the entrance you are looking for. (Alternatively, exit Lakeshore at Congress and head west about 5 blocks.) There are numerous paid parking lots in the area. If you're adamantly opposed to parking structures sometimes a meter can be found, especially on the south side of Congress around Printer's Row. Refreshments will be provided, but unfortunately there will be no live network connection, so if you have something you want to show, bring it along on your laptop. About ChiPy ----------- We meet once a month, on the second Thursday of the month. If you can't come this month, please join our mailing list: http://lonelylion.com/mailman/listinfo/chipy

[ANN] PyScript 0.5 released
by cochrane＠physics.uq.edu.au 10 Jan '05

10 Jan '05

PyScript is a python module for producing high quality postscript graphics. Rather than use a GUI to draw a picture, the picture is programmed using python and the PyScript objects. Some of the key features are: * All scripting is done in python, which is a high level, easy to learn, well developed scripting language. * All the objects can be translated, scaled, rotated, ... in fact any affine transformation. * Plain text is automatically kerned. * You can place abritrary LaTeX expressions on your figures. * You can create your own figure objects, and develop a library of figure primitives. * Output is publication quality. LICENSE: Released under the GPL The major change in this release is a complete rewrite of the Path object. The internals have completely changed and there have been some incompatible changes with previous versions but it's now much closer to what was envisaged for the object. There have also been many bug fixes and minor other improvements. For details see the PyScript web page: <a href="http://pyscript.sourceforge.net">pyscript.sourceforge.net</a>. <P><A HREF="http://pyscript.sourceforge.net">PyScript 0.5</A> - a python module for producing high quality postscript graphics; rather than use a GUI to draw a picture, the picture is programmed using python and the pyscript objects.

itools 0.6.0 released
by "J. David Ibáñez" 06 Jan '05

06 Jan '05

What is it? * itools.uri -- an API to manage URIs, to identify and locate resources. * itools.resources -- an abstraction layer over resources that let to manage them with a consistent API, independently of where they are stored. * itools.handlers -- resource handlers infrastructure (resource handlers are non persistent classes that add specific semantics to resources). This package also includes several handlers out of the box. * itools.xml -- XML infrastructure, includes resource handlers for XML, XHTML and HTML documents. Plus the Simple Template Language. * itools.i18n -- tools for language negotiation and text segmentation. * itools.workflow -- represent workflows as automatons, objects can move from one state to another through transitions, classes can add specific semantics to states and transitions. * itools.catalog -- An Index & Search engine. What's new? Resources - Now "get_resources" is an iterator that returns a resource (not a name) at a time. - Memory folders provide "get_atime". Handlers - Add the methods "get_handler_names", "get_handlers" and "has_handler". - The methods "get_resource", "has_resource", "set_resource", etc. have been removed. Access them throug the "resource" attribute, or use the equivalent handler methods ("get_handler_names", etc). - Now text handlers only must define the method "to_unicode", which now accepts the optional parameter encoding. - The methods "__str__" and "__unicode__" have been removed. Use instead "to_str" and "to_unicode". - Serialization and de-serialization code has been moved from "xml.Schema" to "handlers.IO". Now the code serializes and de-serializes to and from byte strings. XML - The architecture has been cleaned and simplified, specially for attributes, whose API has changed. - The new method "traverse2" makes "walk" obsolete. Simple Template Language - The "stl:if" and "stl:attributes" expressions accept the new "not" operator. This change makes the "stl:ifnot" statement obsolete. Catalog - Now the catalog follows the load/save logic. As a side effect the index and unindex operation has been speeded up but a factor of 2, aproximately. Workflow - Remove the "__init__" method from the "WorkflowAware" class to avoid conflicts with handler classes. Now the method "enter_workflow" must be called explicitly. Documentation - Re-write part of the introduction. - Re-organize the handler chapters. Explain some things for the first time, explain other things better.

python-dev Summary for 2004-11-16 through 2004-11-30
by Brett C 06 Jan '05

06 Jan '05

python-dev Summary for 2004-11-16 through 2004-11-30 ++++++++++++++++++++++++++++++++++++++++++++++++++++ This is a summary of traffic on the `python-dev mailing list`_ from November 16, 2004 through November 30, 2004. It is intended to inform the wider Python community of on-going developments on the list. To comment on anything mentioned here, just post to `comp.lang.python`_ (or email python-list(a)python.org which is a gateway to the newsgroup) with a subject line mentioning what you are discussing. All python-dev members are interested in seeing ideas discussed by the community, so don't hesitate to take a stance on something. And if all of this really interests you then get involved and join `python-dev`_! This is the fifty-third summary written by Brett Cannon (Another quarter begins). To contact me, please send email to brett at python.org ; I do not have the time to keep up on comp.lang.python and thus do not always catch follow-ups posted there. All summaries are archived at http://www.python.org/dev/summary/ . Please note that this summary is written using reStructuredText_ which can be found at http://docutils.sf.net/rst.html . Any unfamiliar punctuation is probably markup for reST_ (otherwise it is probably regular expression syntax or a typo =); you can safely ignore it, although I suggest learning reST; it's simple and is accepted for `PEP markup`_ and gives some perks for the HTML output. Also, because of the wonders of programs that like to reformat text, I cannot guarantee you will be able to run the text version of this summary through Docutils_ as-is unless it is from the `original text file`_. .. _PEP Markup: http://www.python.org/peps/pep-0012.html The in-development version of the documentation for Python can be found at http://www.python.org/dev/doc/devel/ and should be used when looking up any documentation on new code; otherwise use the current documentation as found at http://docs.python.org/ . PEPs (Python Enhancement Proposals) are located at http://www.python.org/peps/ . To view files in the Python CVS online, go to http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/python/ . Reported bugs and suggested patches can be found at the SourceForge_ project page. The `Python Software Foundation`_ is the non-profit organization that holds the intellectual property for Python. It also tries to forward the development and use of Python. But the PSF_ cannot do this without donations. You can make a donation at http://python.org/psf/donations.html . Every penny helps so even a small donation (you can donate through PayPal or by check) helps. .. _python-dev: http://www.python.org/dev/ .. _SourceForge: http://sourceforge.net/tracker/?group_id=5470 .. _python-dev mailing list: http://mail.python.org/mailman/listinfo/python-dev .. _comp.lang.python: http://groups.google.com/groups?q=comp.lang.python .. _Docutils: http://docutils.sf.net/ .. _reST: .. _reStructuredText: http://docutils.sf.net/rst.html .. _PSF: .. _Python Software Foundation: http://python.org/psf/ .. contents:: .. _last summary: http://www.python.org/dev/summary/2004-11-01_2004-11-15.html .. _original text file: http://www.python.org/dev/summary/2004-11-16_2004-11-30.ht ===================== Summary Announcements ===================== PyCon_ is coming up! Being held March 23-25 in Washington, DC, registration is now open at http://www.python.org/pycon/2005/register.html for credit card users (you can pay by check as well; see the general info page for the conference). .. _PyCon: http://www.python.org/pycon/2005/ ========= Summaries ========= --------------------------------------------- Would you like the source with your function? --------------------------------------------- Would you like all functions and classes to contain a __pycode__ attribute that contains a string of the code used to compile that code object? Well, that very idea was proposed. You would use a command-line switch to turn on the feature in order to remove the memory and any performance overhead for the default case of not needing this feature. Some might ask why this is needed when inspect.getsource and its ilk exist. The perk is that __pycode__ would always exist while inspect.getsource is a best attempt but cannot guarantee it will have the source. Beyond a suggested name change to __source__, various people have suggested very different uses. Some see it as a convenient way to save interpreter work easily and thus not lose any nice code snippet developed interactively. Others see a more programmatic use (such as AOP "advice" injection). Both are rather different and led to the thread ending on the suggestion that a PEP be written that specifies what the intended use-case to make sure that need is properly met. Contributing threads: - `__pycode__ extension <http://mail.python.org/pipermail/python-dev/2004-November/049953.html>`__ =============== Skipped Threads =============== - PEP 310 Status - python 2.3.5 release? look for 2.3.5 possibly in January - Current CVS, Cygwin and "make test" - syntactic shortcut - unpack to variably sizedlist mostly discussed `last summary`_ - Python 2.4, MS .NET 1.1 and distutils - Trouble installing 2.4 - Looking for authoritative documentation on packages, import & ihooks no docs exist, but feel free to write some! =) - String literal concatenation & docstrings literal string concatenation only works if the newline separating the strings is not significant to the parser - print "%X" % id(object()) not so nice does 'id' need to return only a positive? No, but it would be nice. - Bug in PyLocale_strcoll - Multilib strikes back - File encodings file.write does not work with Unicode strings; have to decode them to ASCII on your own

Roundup Issue Tracker release 0.7.11
by Richard Jones 05 Jan '05

05 Jan '05

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Roundup is a simple-to-use and -install issue-tracking system with command-line, web and e-mail interfaces. It is based on the winning design from Ka-Ping Yee in the Software Carpentry "Track" design competition. 0.7.11 is a bug fix release: - - index args URL generation broken in .10 (sf bug 1096027) - - handle NotModified for non-static files (sf patch 1095790) - - fix permission lookup in query editing If you're upgrading from an older version of Roundup you *must* follow the "Software Upgrade" guidelines given in the maintenance documentation. Roundup requires python 2.1.3 or later for correct operation. To give Roundup a try, just download (see below), unpack and run:: python demo.py Source and documentation is available at the website: http://roundup.sourceforge.net/ Release Info (via download page): http://sourceforge.net/projects/roundup Mailing lists - the place to ask questions: http://sourceforge.net/mail/?group_id=31577 About Roundup ============= Roundup manages a number of issues (with flexible properties such as "description", "priority", and so on) and provides the ability to: (a) submit new issues, (b) find and edit existing issues, and (c) discuss issues with other participants. The system will facilitate communication among the participants by managing discussions and notifying interested parties when issues are edited. One of the major design goals for Roundup that it be simple to get going. Roundup is therefore usable "out of the box" with any python 2.1+ installation. It doesn't even need to be "installed" to be operational, though a disutils-based install script is provided. It comes with two issue tracker templates (a classic bug/feature tracker and a minimal skeleton) and seven database back-ends (anydbm, bsddb, bsddb3, sqlite, metakit, mysql and postgresql). -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (GNU/Linux) iD8DBQFB3G+LrGisBEHG6TARAqyAAJ9oE1XWDf2HrnMMQm/j8U3o4Pbj7wCfb+B5 7MeaSyo0z1obhhcK1U19Z/M= =xGfA -----END PGP SIGNATURE-----

Spread Module 1.5 alpha 1 released
by Tim Peters 05 Jan '05

05 Jan '05

Release 1.5a1 of the Spread Module for Python is available from a new home: http://zope.org/Members/tim_one/spread About the Spread Module ----------------------- This package contains a simple Python wrapper module for the Spread toolkit (see below). It wraps Spread mailboxes and messages in Python objects with appropriate methods and attributes, and turns Spread errors into Python exceptions. Virtually all Spread features are accessible from Python. It's intended to be used with Spread 3.17.3 and Python 2.3.4, although other combinations are possible. A source tarball is available, and a Windows installer with a precompiled spread.pyd (which must be used with a Python in the 2.3 line). About Spread ------------ >From the Spread website (<http://www.spread.org>): Spread is a toolkit that provides a high performance messaging service that is resilient to faults across external or internal networks. Spread functions as a unified message bus for distributed applications, and provides highly tuned application-level multicast and group communication support. Spread services range from reliable message passing to fully ordered messages with delivery guarantees, even in case of computer failures and network partitions. Spread is designed to encapsulate the challenging aspects of asynchronous networks and enable the construction of scalable distributed applications, allowing application builders to focus on the differentiating components of their application. Changes since release 1.4 ------------------------- Very little has changed: an obscure alignment bug triggered by people who changed #define's in Spread's own header files was fixed, and the Windows setup was changed to work with Spread 3.17.3. See the download page for details. Since so little has changed, 1.5 final will probably be released next.

ANN: Kamaelia's Axon 1.0.1 released
by Michael Sparks 05 Jan '05

05 Jan '05

Axon 1.0.1 has been released! What is it? =========== Axon is a collection of pure python modules from the Kamaelia project which allow you to build concurrent systems in a compositional manner using communicating python generators. Components are python generators are augmented by inbox and outbox queues (lists) for communication in a CSP like fashion. Put another way this allows you to build complex systems out of small concurrent components in a fashion similar to unix pipelines, except rather than being limited to just stdin/stdout you can have whatever inputs/outputs you desire. (The defaults are inbox/outbox, control/signal) Axon should be relatively feature complete and the API stable, given its design has been fleshed by use in the Kamaelia project. Given Kamaelia components for building network servers, pygame wrappers & vorbis playback have been written using Axon so far, we expect that Axon should be useful for other areas where multiple activities need to be handled within a single thread, whilst allowing the code to remain looking more or less single threaded. Documentation is generated directly from the test suite output. What's new in version 1.0.1? ============================ * API documentation has been added (though a work in progress!) Where can I get it? =================== Axon is a sub-project of the BBC R&D Kamaelia project, which means Axon is downloadable from http://sourceforge.net/projects/kamaelia/ Web pages are here: http://kamaelia.sourceforge.net/Docs/Axon.html http://kamaelia.sourceforge.net/ (includes info on mailing lists) ViewCVS access is available here: http://cvs.sourceforge.net/viewcvs.py/kamaelia/ Best Regards, Michael. -- Michael.Sparks(a)rd.bbc.co.uk British Broadcasting Corporation, Research and Development Kingswood Warren, Surrey KT20 6NP This message (and any attachments) may contain personal views which are not the views of the BBC unless specifically stated.

Movable Python
by Fuzzyman 05 Jan '05

05 Jan '05

Movable Python has just been released on sourceforge. Movable Python is a frozen distribution of Python. It will run python scripts without needing to be installed. http://sourceforge.net/projects/movpy http://www.voidspace.org.uk/python/movpy Fancy trying out Python 2.4 without installing it ? Want a distribution of python you can carry around on a flash card ? Need to test scripts with several versions of python ? Movable Python may be for you. Features include : * Lightweight GUI for choosing scripts to run * Interactive interpreter mode * Understands many of the python command line options * Configurable distribution builder * Pre built environments come with IPython and psyco * The standard distribution includes wxPython and SPE (the python IDE) making it an ideal 'Build, Test and Run' environment * Additional modules can be easily added - either when building distribution or to a prebuilt environments The docs are online at voidspace. The distribution builder (source) and two prebuilt environments (for python 2.4) can be downloaded from sourceforge. Distributions are built using py2exe. Running PyDistFreeze.py (the 'source') needs py2exe installed. This also means the source and distributions are currently windoze only. We are interested in porting to mac (with py2app) and Linux (cx_freeze ?). This was previously available as testenv 'Test Environment'.. Recent changes include : 2005/01/02 Version 0.4.4 More changes by Michael When not using IPython, interactive() will find locals() for itself. (Meaning interactive() can be called in user scripts) Added the 'manuals' folder to the distribution. Added the -p command line option, to switch on psyco. Switched to using compile/eval rather than exec/execfile. (Better for psyco *and* more meaningful error messages) A fix so that errors will report the right line number with '-x'. Changed config file to include winsound and unicodedata. Modifications to PyDistFreeze.py and movpy.py to make them compatible with python 2.2. A built in 'setup.py' for python 2.2. (can now autobuild distributions on python 2.2) IPython should now work on machines that don't have it installed ! (ipythondir is now set and config file supplied) If you don't select a file from the GUI, it now drops into interactive mode. Can supply path to config.txt in command line to PyDistFreeze.py Tweaked the directory finding function - which finds directories we will search. Fixed it so that movpyw doesn't generate error logs with '-' if launched from GUI with no file. Added PyDistFreeze.bat IDLE now works, so added idle.bat. 2004/12/31 Version 0.4.3 Support for IPython as alternative interactive shell. External config file ('config.txt' in 'lib/' directory) - for setting default command line options. Added 'credits' and 'copyrights' as builtins (for IPython). 2004/12/28 Version 0.4.2 Another set of changes by Michael Foord. Added support for command line arguments -h, -V, -u, -i, -x, -, -c (hey that's a lot for one evening !) The main script 'movpy.py' is now kept in an external file. 'include_modules' now supports sub-packages. Added back support for encodings. packagepaths.pth added for sub-package support with 'include_packages'. 2004/12/29 Version 0.4.1 Lots of changes by Michael Foord. They include : addition of customize.py addition of syspaths.pth Cleans up intermediate files. Copies packages properly. Only copies the microsoft Visual C 7 dlls if built with Python 2.4. Addition of unicows dll is optional. Addition of spe.bat. Builds the windows version - movpyw.exe Added the manifest files. Added the build option. 2004/12/19 Version 0.4 Several important changes by Bruno Thoorens. These include : Lightweight GUI frontend added to movpy.exe. setup.py incorporated into main script - name changes to PyDistFreeze.py Icon added. 2004/12/18 Version 0.3 More work with Stani. '.pth' files now supported. Importing from '.pyc' etc. as well as straight '.py' files. Added external config file, using ConfigObj. 2004/12/17 Version 0.2 Renamed 'Movable Python'. (Executable is 'movpy.exe') Cleaned up a lot - now imports subpackages properly. Thanks to Stani of SPE for encouragement and suggestions. (including the name) 2004/12/14 Version 0.1 Test version called 'testenv' - Python test environment. Works better than expected. Thanks to Bruno Thoorens and Stani for help and debugging.

ANN: Urwid 0.8.6
by Ian Ward 04 Jan '05

04 Jan '05

Announcing Urwid 0.8.6 ---------------------- Urwid home page: http://excess.org/urwid/ Tarball: http://excess.org/urwid/urwid-0.8.6.tar.gz Current Urwid users PLEASE NOTE: ================================ This version of Urwid changes the default foreground and background for areas of the screen with no attributes. You may need to AttrWrap(..) some of your widgets for your program to look the same. New in this release: ==================== - Improved support for CJK double-byte encodings: BIG5, UHC, GBK, GB2312, CN-GB, EUC-KR, EUC-CN, EUC-JP (JISX 0208 only) and EUC-TW (CNS 11643 plain 1 only) - Added support for ncurses' use_default_colors() function to curses_display module (Python >= 2.4). register_palette(..) and register_palette_entry(..) now accept "default" as foreground and/or background. If the terminal's default attributes cannot be detected black on light gray will be used to accommodate terminals with always-black cursors. "default" is now the default for text with no attributes. This means that areas with no attributes will change from light gray on black (curses default) to black on light gray or the terminal's default. - Modified examples to not use black as background of Edit widgets. - Fixed curses_display curs_set call so that cursor is hidden when widget in focus has no cursor position. About Urwid =========== Urwid is a curses-based UI library for Python. It features fluid interface resizing, CJK support, multiple text layouts, simple attribute markup, powerful scrolling list boxes, flexible edit boxes and HTML screen shots.

IMDbPY 1.6 released
by alberanid＠libero.it 03 Jan '05

03 Jan '05

IMDbPY 1.6 is available (tgz, deb, rpm, exe) from: http://imdbpy.sourceforge.net/ IMDbPY is a Python package useful to retrieve and manage the data of the IMDb movie database. This release fixes a lot of bugs; moreover every reference to movies and persons in fields like "plot" or "biography" is collected. IMDbPY aims to provide an easy way to access the IMDb's database using a Python script. Platform-independent and written in pure Python, it's independent from the data source (since IMDb provides two or three different interfaces to their database). IMDbPY is mainly intended for programmers and developers who want to build their Python programs using the IMDbPY package, but some example scripts - useful for simple users - are included. -- Davide Alberani <alberanid(a)libero.it> [PGP KeyID: 0x465BFD47] http://erlug.linux.it/~da/

XIST 2.8 released
by Walter Dörwald 03 Jan '05

03 Jan '05

XIST 2.8 has been released! What is it? =========== XIST is an extensible HTML/XML generator written in Python. XIST is also a DOM parser (built on top of SAX2) with a very simple and Pythonesque tree API. Every XML element type corresponds to a Python class, and these Python classes provide a conversion method to transform the XML tree (e.g. into HTML). XIST can be considered "object oriented XSL". What's new in version 2.8? ========================== * XIST requires Python 2.4 now. * ll.xist.ns.specials.x has been renamed to ll.xist.ns.specials.ignore. ll.xist.utils.findAttr has been renamed to ll.xist.utils.findattr. * ll.xist.xfind.item no longer handles slices. * XFind has been enhanced to support item and slice operators, i.e. if foo is an XFind operator, foo[0] is an operator that will produce the first node from foo (if there is one). Negative values and slices are supported too. * Operators can be chained via division: html.a/html.b is an operator that can be passed around and applied to a node. * XIST requires the new core module and makes use of the new "cooperative displayhook" functionality defined there: If you install the displayhook you can tweak or replace ll.xist.presenters.hookpresenter to change the output. For changes in older versions see: http://www.livinglogic.de/Python/xist/History.html As the package structure has changed, there is a new version of every other LivingLogic package too. Furthermore the web pages have been redesigned. Where can I get it? =================== XIST can be downloaded from http://ftp.livinglogic.de/xist/ or ftp://ftp.livinglogic.de/pub/livinglogic/xist/ Web pages are at http://www.livinglogic.de/Python/xist/ ViewCVS access is available at http://www.livinglogic.de/viewcvs/ For information about the mailing lists go to http://www.livinglogic.de/Python/xist/Mailinglists.html Bye, Walter Dörwald

Ann: CherryPy-2.0-beta released
by remi＠cherrypy.org 03 Jan '05

03 Jan '05

Hello everyone, I am happy to announce the release of CherryPy-2.0-beta. CherryPy-2 is a pythonic, object-oriented web development framework. CherryPy-2 is a redesign of CherryPy-1 (the unpythonic features have been removed): no more compilation step, pure python source code (no more "CherryClass") Here is a sample Hello, World in CherryPy-2: # from cherrypy import cpg # class HelloWorld: # @cpg.expose # def index(self): # return "Hello world!" # cpg.root = HelloWorld() # cpg.server.start() Main properties: - this code starts a multi-threaded HTTP server that dispatches requests to methods - requests like "http://domain/dir/page?arg1=val1&arg2=val2" are mapped to "dir.page(arg1='val1', arg2='val2')" - requests are mapped to an object tree that is "mounted" on cpg.root (for instance: "cpg.root.user", "cpg.root.user.remi", ...) - method must be explicitely exposed with a decorator "@cpg.expose" (or "index.exposed = True" for Python-2.3) - methods can return a generator instead of a string (useful when generating big pages) Here is a non-exhaustive list of CherryPy-2 features: multi-threaded HTTP server, XML-RPC server, sessions, form handling, authentication, unicode support, gzip-compression, virtual hosting, WSGI adapter (experimental) The design of CherryPy-2 allows to easily write/use pluggable "filters" or "modules": - filters perform operations on the request/response such as gzip-compression or string encoding - modules are web applications (like a blog or a web forum) than can be easily "mounted" anywhere you want in your website CherryPy-2 is already used in production by several sites and is supported by an active community. Remi. http://www.cherrypy.org

ANN: PyXR 0.9.4 - Cross-Referenced HTML from Python Source
by olsongt＠verizon.net 02 Jan '05

02 Jan '05

PyXR 0.9.4 - Cross-Referenced HTML from Python Source PyXR generates pretty-printed HTML pages from python source files to make source browsing easier. It provides extensive cross-referencenced hyperlinks that integrate with the Python Library Reference as well as other python source files. Its cross-referencing capabilities are vastly superior to other source pretty-printing packages that I've seen. 0.9.4 provides compatibility with the new language semantics in Python 2.4 and addresses changes to the format of the Library Reference Manual, in addition to a littany of smaller fixes. Previous versions WILL NOT work with python 2.4. This release does provide backward compatibility to python versions as early as 2.2 and should work on all major OSes. PyXR is available for download here: http://sourceforge.net/projects/pyxr/ PyXR'ed markup of Python 2.4's source is available here: http://pyxr.sourceforge.net/PyXR/ Detailed release notes are available here: http://pyxr.sourceforge.net/ Enjoy!

SPyRE version 0.6 -> Simple Pythonic Rendering Engine
by David 01 Jan '05

01 Jan '05

The "Pitcher's Duel" project has released SPyRE (Simple Pythonic Rendering Engine) version 0.6. This is a lightweight rendering engine for OpenGL. Provide OpenGL code to draw the model, and the SPyRE engine will display the model in an interface that provides zooming, panning and rotation of camera position using mouse and keyboard. Our goal is to use the engine for a baseball simulation, but it should be generic enough for a variety of applications. Changes in this release include bug fixes to the only reported bug (an initialization problem), and to a glitch in the pivoting code. This release has 'epydoc' documentation, more detailed than the prior docs, and rewritten summary docs. The project includes demos such as a fountain of sparks, a swarming behavior model, a random walk example, a whirlpool effect using gravity and drag, and an example of chaos theory, and a lighted shaded forest scene. The project page is at http://sourceforge.net/projects/pduel/spyre/ To use SPyRE, you also need to have installed Python, OpenGL, pyOpenGL, and PyGame.
