[ANNOUNCE] gmpy 1.0 alpha released
by Alex Martelli 13 Nov '05

13 Nov '05

See http://gmpy.sourceforge.net/ for details. What is it: a wrapper for the GMP library, to provide multi-precision arithmetic for Python. Multi-precision floats, and unbounded-precision rationals, are not present in stock Python; multi-precision integers ('long') are, but gmpy's version of multi-precision integers is faster for some operations (NOT all -- used to be, but Python 2.3 did serious enhancements to some operations on longs) and provides lots of nifty pre-packaged additional functions. Minor changes and bug-fixes since the latest 0.9 pre-alpha; support for Python 2.3. The Windows binary release is now for Python 2.3 _only_ (if you're stuck with Python 2.2 on Windows, you can keep using gmpy 0.9 pre-alpha and not really suffer from that). Known bug on Windows: the scan0 and scan1 functions appear broken (perhaps related to the lack of a GMP 4.0 library for Windows -- haven't found one around yet). Alex

pre-announce: Python 2.4a1 is about a month away
by Anthony Baxter 31 May '04

31 May '04

This is a pre-announcement that the first alpha of Python 2.4 is about a month away. The purpose of this notice is to give people a heads up - if you have a bug that you want to see fixed for 2.4, start looking at it now. Fixes are welcome through the release cycle, although after the first beta fixes that result in a change to behaviour will be much less likely to be accepted. So, if you have a bug you want to see fixed, what should you do? - If it's not logged on SF, log it. - If it's logged, consider adding a patch that fixes the problem, or at least a simple test case that demonstrates the bug. - If someone else has supplied a fix, see if this fix works for you, and post your results to the bug. - If there's a working fix, feel free to add a note asking for the fix to go into CVS. The SF bug tracker for Python has a _lot_ of bugs in it, and it's easy for bugs to be overlooked. If you're just interested in what's coming up in 2.4, see the current development version of the "What's New in 2.4" document at http://www.python.org/dev/doc/devel/whatsnew/whatsnew24.html On behalf of the python-dev team, thanks! Anthony [This form of pre-announcement will hopefully become a part of the release process for all future releases of Python, both major and bugfix releases, to give people a chance to get their bugfix-of-choice submitted in time. Any feedback on this process, please feel free to email me] -- Anthony Baxter <anthony(a)interlink.com.au> It's never too late to have a happy childhood.

a small bugfix release only, for full details see http://cthedot.de/pyxsldoc/ changes since the last release ------------------------------ * xsl:import and xsl:include information on the doc pages are not linked anymore as they may be not working anyway. this is because of not compatible cross XSLT processor or configuration behaviour. even pyXSLdocs own documentation was not working as Pyana expects href to be relative to the calling app. pyXSLdoc always assumed URIs relative to the importing or including stylesheet see http://cthedot.de/pyxsldoc/README.txt for a complete list of changes license ------- pyXSLdoc is published under the LGPL. download -------- download pyXSLdoc v0.51 - 040531 from http://cthedot.de/pyxsldoc/ pyXSLdoc needs * Python 2.3 (tested with Python 2.3.4 on Windows XP only) * Pyana (tested with Pyana 0.8 only) * Docutils (tested with Docutils 0.3 only) for ReST comments not neccessary if you use Javadoc style comments usage ----- Easiest is to copy the XSLT files to document in a directory below pyxsldoc. Then start the documentation process with python xsldoc.py FILENAMES DIRNAMES [options] FILENAMES XSLT files to document, e.g. file1.xsl path/file2.xsl DIRNAMES directories with XSLT files to document,e.g. dir1 dir2 all directories and XSLT files under a given directory will be processed. this is new from v0.50 options ======= Please use the new option syntax, e.g. -dDOCPATH instead of -d DOCPATH, so no more blank between option and value (optparse expects this syntax, the former selfmade solution was a bit odd there...) -h, --help show this help message and exit -sSOURCEPATH, --sourcepath=SOURCEPATH sourcepath to XSLTs, all XSLT files under this path will be documented and SOURCEPATH/overview.txt will be used for the overview. You might also simply list all dirs and XSLT files as parameters. -j, --javadoc, --htmldocs process comments in Javadoc style (HTML and @tags), default style is reStructuredText (ReST) -dDOCPATH, --docpath=DOCPATH documentation target directory, default is ./_xsldoc (ATTENTION: Was option -b in versions upto v0.3x) -oOVERVIEW, --overview=OVERVIEW use this ReST .txt file for the overview page -r, --removedocs remove all comments from given XSLTs and save results in COMMENTSTRIPPEDPATH. present files will all be OVERWRITTEN! -cCOMMENTSTRIPPEDPATH, --commentstrippedpath=COMMENTSTRIPPEDPATH path where XSLTs after removing of all docs will be saved, only used when option "-r" is given. default is _optimized. christof hoeke http://cthedot.de <P><A HREF="http://cthedot.de/pyxsldoc/">pyXSLdoc 0.51</A> - generate XSLT documentations (31-May-04)

ANN: PyObjC 1.1
by Ronald Oussoren 31 May '04

31 May '04

PyObjC 1.1 is now available for download at http://pyobjc.sourceforge.net/ PyObjC is a bridge between Python and Objective-C. It allows full featured Cocoa applications to be written in pure Python. It is also easy to use other frameworks containing Objective-C class libraries from Python and to mix in Objective-C, C and C++ source. Python is a highly dynamic programming language with a shallow learning curve. It combines remarkable power with very clear syntax. The installer package includes a number of Xcode and Project Builder templates for easily creating new Cocoa-Python projects, as well as support for syntax-coloring Python files. PyObjC also supports full introspection of Objective-C classes and direct invocation of Objective-C APIs from the interactive interpreter. PyObjC requires MacOS X 10.2 or later. PyObjC works both with the Apple provided Python installation in MacOS X 10.2 (and later) and with MacPython 2.3. Users of MacPython 2.3 can install PyObjC though the PackageManager application. The major improvement of PyObjC 1.1 is support for Key-Value Observing. It is now possible to write programs that use Cocoa Bindings. There are also numerous new examples. PyObjC is released with an open source license.

ANN: pyXSLdoc v0.50
by csad7＠t-online.de 30 May '04

30 May '04

what is it ---------- An application to produce documentation for XSLT files in XHTML format, similar to what javadoc does for Java files. Relying on and processing XML comments is generally not the best idea but for the purpose of this tool it seems the easiest, most natural and comfortable way. Even if the XML comments should not be processed (an XML parser might just ignore them), pyXSLdoc should at least give a helpful outline for a set of XSLT stylesheets. changes since the last release ------------------------------ * all directories and files *under* a specified sourse directory will be processed now, so you need no longer specify each directory of a larger package * also overview files in ReST style (directory.txt and overview.txt) are processed now * optparse is used to process the command line options, see -h for all new options and option formats * the target dir or -removedocs which strips off all comments from the commented XSLT files may be specified now * bugfixes and small changes see http://cthedot.de/pyxsldoc/README.txt for a complete list of changes todo ---- * ReST processing is very simple at the moment, may be resolved and enhanced in a future version license ------- pyXSLdoc is published under the LGPL. download -------- download pyXSLdoc v0.50 - 040530 from http://cthedot.de/pyxsldoc/ pyXSLdoc needs * Python 2.3 (tested with Python 2.3.4 on Windows XP only) * Pyana (tested with Pyana 0.8 only) * Docutils (tested with Docutils 0.3 only) for ReST comments not neccessary if you use Javadoc style comments usage ----- Easiest is to copy the XSLT files to document in a directory below pyxsldoc.

pyshapelib 0.3 released
by Bernhard Herzog 28 May '04

28 May '04

pyshapelib 0.3 released pyshapelib is a python wrapper for shapelib[1], a free software library for reading and writing ESRI shapefiles, a frequently used format for geographic data. Download: http://ftp.intevation.de/users/bh/pyshapelib/pyshapelib-0.3.tar.gz or http://ftp.intevation.de/users/bh/pyshapelib/pyshapelib-0.3.zip Changes since version 0.2: * New module shptree. It's a simple wrapper for shapelib's quadtree. * Provide a way to access the shapelib module and shapefile objects from C. It's not documented, unfortunately, but pyshapelib_api.h may be a starting point. This feature is used in Thuban[2] which could be used as an example. * distutils based build and install script, setup.py Module dbflib: * dbf objects now have a method commit if compiled with shapelib newer than 1.2.10 (that is only the CVS version of shapelib at the time of writing). This method calls the new function dbflib DBFUpdateHeader. * New method read_attribute which reads a single attribute instead of a whole record like read_record * NULL values are now returned as None. DBF files don't really support NULL, but this change matches a new feature in shapelib 1.2.9. It's not clear whether it should be implemented in the python wrapper in this way. It might be better to make it optional. Requirements: Python 2.0 or later (mostly tested with 2.2, though) shapelib 1.2.9 or later License: LGPL Links: [1] Shapelib: http://gdal.velocet.ca/projects/shapelib. [2] Thuban is an interactive geographic data viewer. http://thuban.intevation.org/

Zope X3 3.0.0 alpha 2 released
by Stephan Richter 28 May '04

28 May '04

Dear Python community, The Zope 3 development team is proud to announce the second alpha release of Zope X3 3.0.0. Zope X3 is the next major Zope release and has been written from scratch based on the latest software design patterns and the experiences of Zope 2. The "X" in the name stands for "experimental", since this release does not try to provide any backward-compatibility to Zope 2. Download http://zope.org/Products/ZopeX3 Installation instructions for both Windows and Un*x/Linux are now available in the top level README.txt of the distribution. Changes since alpha 1 - Several packages were included in the first alpha since other code had several dependencies on their interfaces. This code has been refactored into sub-packages which are no longer part of the release. As a result, this distribution has fewer packages than alpha 1. Excluded packages include the indexing and fssync. - Some bugs were fixed that were reported by testers. This includes problems with the installation of a distribution. Goals While the first alpha release concentrated on testing our packaging tool and putting a process for releases into place, we would like to ask anyone to test this release a thoroughly as possible. The next release will be the first beta (probably next week) at which time the API freezes! Even if you are not interested in Zope you should test the building process of the distribution, since the packaging tool might be of great interest to the entire Python community. Please send any bug reports and comments to zope3-dev(a)zope.org! Thank you very much in advance for your help! Contributors Jim Fulton, Marius Gedminas, Fred Drake, Philipp von Weitershausen, Stephan Richter, Dmitry Vasiliev, Eckart Hertzler Thanks to everyone!
