by Gerrit Holl 24 Jun '03

24 Jun '03

Brian 0.1.2 has been released at Tue, 24 Jun. WHAT IS BRIAN ============= Brian is an unfinished jump-and-run platform game. It is written in the Python programming language, using the Pygame library (on top of SDL). Although it will be an independant project, it will be inspired by Commander Keen. It will be written using a Linux workstation, but it should be crossplatform for all major platforms (Linux, Windows). It is called Brian after "Monty Python's Life of Brian", and the game may contain some references. Currently, Brian includes the following features: * Player score * Multiple resolutions * Monsters * Random levels * Level editor * Level exits * Perspective * Music * Sound (very limited) * And more, but don't expect it to be very much fun yet WHATSNEW ======== * Windows version now works * Fire's have a variable size * Multiple backgrounds now possible and edible * Walls now have perspective, engine should work for other sprites too * Brian appears behind walls when he's on the left * Don't load data if we don't need it * Many bugfixes * Many internal fixes * See NEWS file for details * See CVS logs for even more details MORE INFORMATION ================ Visit http://pybrian.sourceforge.net/ for more information.

TTFQuery 0.2.4 available (from SourceForge)
by Mike C. Fletcher 24 Jun '03

24 Jun '03

TTFQuery builds on the FontTools module to allow the Python programmer to query TTF font-files for metadata and glyph outlines. This allows the programmer to find (system) fonts based on family, name or decoration (italics, weight). It is currently used by OpenGLContext to provide outline and extruded font forms within OpenGL. http://sourceforge.net/projects/ttfquery/ By popular demand, v0.2.4 includes support for querying the registry on Win32 systems to find all registered fonts, not merely those in the standard fonts directory. It also includes the documented Mac OS X font directories in the list of default search paths. FontTools: http://sourceforge.net/projects/fonttools/ OpenGLContext: http://pyopengl.sourceforge.net/context/ Enjoy, Mike _______________________________________ Mike C.

dnspython 1.0.0b3 has ben released. It is pretty much the same as 1.0.0b2, but I have renamed the containing module from "DNS" to "dns" to avoid conflicting with the PyDNS module. /Bob

Toronto-area Python user group meets Tuesday, June 24, 8pm
by Peter Hansen 23 Jun '03

23 Jun '03

The next meeting of PyGTA, the most excellent Toronto-area user group for all things Python, will be at the usual location (519 Church St. near Wellesley) and time. See http://web.engcorp.com/pygta/wiki/NextMeeting for details. We haven't received confirmation of the hoped-for presentation involving Python- generated SVG yet, which will likely mean we'll be subjected to a TDDious demonstration by Peter Hansen on doing test-driven development with Python, or something awful like that. Maybe we can limit his enthusiasm simply to showing how to use PyUnit to write simple unit tests. Remember, the more people come out to attend, the more likely the discussion will be interesting enough that we won't have to resort to such awful things! If you are "more people", plan to attend! Better yet, bring a friend, or grab someone off the street on your way there, and introduce him or her to Python... -Peter Hansen, Ian Garmaise, meeting organizers, and the other PyGTA faithful :-) Note: if you would like a CDROM-equipped laptop and an LCD projector to be made available for a demonstration, you must email Peter prior to 16:00 on Tuesday. Note also: the post-meeting sugar-and-caffeine-fest will of course occur at Just Desserts, as usual.

New News: === ==== I have updated the version of Python to 2.2.3-2. The tarballs should be available on a Cygwin mirror near you shortly.

The -2 package corrects the above. Otherwise, this package should be identical to the previous one. Just in case anyone is interested, this was the first time I built a Python 2.2.x on my new PC. I guess I'm guilty of failing to read my own README. :,) Specifically, the following item: 2. The _tkinter extension module will only be built if the X11 header files from the tcltk-20030214-1 source archive have been copied to /usr/include: [snip] Old News: === ==== Python is an interpreted, interactive, object-oriented programming language. If interested, see the Python web site for more details: http://www.python.org/ Please read the README file: /usr/doc/Cygwin/python-2.2.3.README since it covers requirements, installation, known issues, etc. To update your installation, click on the "Install Cygwin now" link on the http://cygwin.com/ web page. This downloads setup.exe to your system. Then, run setup and answer all of the questions. Note that we have recently stopped downloads from sources.redhat.com (aka cygwin.com) due to bandwidth limitations. This means that you will need to find a mirror which has this update. In the US, ftp://mirrors.rcn.net/mirrors/sources.redhat.com/cygwin/ is a reliable high bandwidth connection. In Germany, ftp://ftp.uni-erlangen.de/pub/pc/gnuwin32/cygwin/mirrors/cygnus/ is usually pretty good. In the UK, http://programming.ccp14.ac.uk/ftp-mirror/programming/cygwin/pub/cygwin/ is usually up-to-date within 48 hours. If one of the above doesn't have the latest version of this package then you can either wait for the site to be updated or find another mirror. The setup.exe program will figure out what needs to be updated on your system and will install newer packages automatically. If you have questions or comments, please send them to the Cygwin mailing list at: cygwin(a)cygwin.com . I would appreciate if you would use this mailing list rather than emailing me directly. This includes ideas and comments about the setup utility or Cygwin in general. If you want to make a point or ask a question, the Cygwin mailing list is the appropriate place. *** CYGWIN-ANNOUNCE UNSUBSCRIBE INFO *** If you want to unsubscribe from the cygwin-announce mailing list, look at the "List-Unsubscribe: " tag in the email header of this message.

SimpleParse 2.0.1a1 released
by Mike C. Fletcher 23 Jun '03

23 Jun '03

A new SimpleParse release, which adds optimisations to reduce terminal productions (and thereby speed up certain types of very formally specified grammars) is now available. For affected grammars, it's quite possible to see speedups of 2x compared with v 2.0.0 of the package. It is strongly recommended that you use mxTextTools 2.1.0 with the 2.0.1 release of SimpleParse. Download and documentation: http://simpleparse.sourceforge.net/ What is SimpleParse: SimpleParse is a BSD-licensed <http://simpleparse.sourceforge.net/#License> Python package providing a simple parser generator for use with the mxTextTools <http://www.lemburg.com/files/python/mxTextTools.html> text-tagging engine. SimpleParse allows you to generate tagging tables for use with the text-tagging engine directly from your EBNF grammar. Enjoy, Mike _______________________________________ Mike C.

ANN: Pyrex 0.8
by Greg Ewing (using news.cis.dfn.de) 23 Jun '03

23 Jun '03

Pyrex 0.8 is now available: http://www.cosc.canterbury.ac.nz/~greg/python/Pyrex/ This release introduces a new compile-time import mechanism for sharing declarations between Pyrex modules, and a new and better way of getting access to external extension types. There are also a few other improvements and bug fixes. Note: There is a small backwards-incompatible change that will require you to make a slight modification to any 'extern' extension type declarations that you have. See the CHANGES.txt file for full details. What is Pyrex? -------------- Pyrex is a new language for writing Python extension modules. It lets you freely mix operations on Python and C data, with all Python reference counting and error checking handled automatically. -- Greg Ewing, Computer Science Dept, University of Canterbury, Christchurch, New Zealand http://www.cosc.canterbury.ac.nz/~greg

ANN: Design By Contract for Python 1.0 beta 3
by Terence Way 22 Jun '03

22 Jun '03

Announcing Design By Contract for Python 1.0 beta 3 (Changes since last announcement at end of this email) Design by Contract is familiar to anyone who has spent time with the Eiffel programming language. This implementation is a cross between full Eiffel-style contracts and the doctest module. Contracts are high-level assertions that are part of the program's documentation. Modules and classes have invariants, expressions that must be true at the start and end of every public function or method call. Methods and functions have pre-conditions, expressions that must be true on entry; and post-conditions, expressions that must be true on exit. http://www.wayforward.net/pycontract/ This version supports the full contract feature set: * pre: expressions in function and method docstrings; * post: expressions in function and method docstrings; * inv: expressions in class and module docstrings; * post: expressions can access __old__ values and the __return__ value; * pre: expressions are weakened by derived methods; and * post: and inv: expressions are tightened by derived classes. Version 1.0 beta 3 - 21 June 2003 * Support Jython (possibly Python 2.1) * Support Python 2.2 (doesn't have bool, True, False: those are added in Python 2.2.1) * Partial contract checking - by default in __debug__ mode checks all contracts, otherwise only check pre-conditions and invariants on entry * Can now pass in module names to checkmod()... This makes it easy to enable contracts: just do a contract.checkmod(__name__) at the end of a module. <P><A HREF="http://www.wayforward.net/pycontract/">Contract 1.0 beta3</A> - Design By Contract for Python.

Excerpt from PostgreSQL Weekly News - Python Support
by Nicola Larosa 22 Jun '03

22 Jun '03

Subject: [ANNOUNCE] PostgreSQL Weekly News - June 18th 2003 Date: 19 Jun 2003 19:09:50 -0400 From: Robert Treat <xzilla(a)users.sourceforge.net> To: pgsql-announce(a)postgresql.org == PostgreSQL Weekly News - June 18th 2003 == ... Theres been a bit of discussion (and some fixes) regarding python support as of late. The fixes include improving the way which python input converter to use is decided, and fixing some issues in setup.py. The discussion revolves around the fact that there have been a number of changes in Python versions greater than 2.2.3 which makes our current support of plpython somewhat broken. Some folks have talked about revamping the language to be used only as an untrusted language, if your interested in helping to maintain this package please post a note to the pgsql-interfaces list. This is something that the core team is not likely to work on so it would be really great if someone can step up to the plate. ... -- Nicola Larosa - nico(a)tekNico.net
