ANNOUNCE: PyQwt-4.1
by Gerard Vermeulen 21 Nov '04

21 Nov '04

I am proud to announce PyQwt-4.1. What is PyQwt? - it is a set of Python bindings for the Qwt C++ class library which extends the Qt framework with widgets for scientific, engineering and financial applications. It provides a widget to plot 2-dimensional data and various widgets to display and control bounded or unbounded floating point values. - it requires and extends PyQt, a set of Python bindings for Qt. - it really shines with either Numeric, numarray or both. Numeric and/or numarray extend the Python language with new data types which turn Python into an ideal system for numerical computing and experimentation, better than MatLab and IDL. - it supports the use of PyQt, Qt, Qwt, the Numerical Python extensions (either Numeric, or numarray or both) and optionally SciPy in a GUI Python application or in an interactive Python session. - it runs on POSIX, MacOS/X and Windows (any operating system supported by Qt and Python). The home page of PyQwt is http://pyqwt.sourceforge.net. Main changes in PyQwt-4.1: 1. supports PyQt-3.13, -3.12, PyQt-3.11, and PyQt-3.10. 2. supports sip-4.1.1, -4.1, -4.0, sip-3.11, and sip-3.10. 3. supports Qt-3.3.3 downto -2.3.0. 4. based on Qwt-4.2.0. 5. either links with a shared (dll) Qwt-4.2.0 library or links statically with a slightly patched internal version of Qwt-4.2.0. Have fun -- Gerard Vermeulen

ANN: 4Suite 1.0a4
by Uche Ogbuji 20 Nov '04

20 Nov '04

Today we release 1.0 alpha 4, now available from Sourceforge and ftp.4suite.org. 4Suite is a comprehensive platform for XML and RDF processing, with base libraries and a server framework. It is implemented in Python and C, and provides Python and XSLT APIs, Web and command line interfaces. For general information, see: http://4suite.org http://uche.ogbuji.net/tech/4Suite/ http://uche.ogbuji.net/tech/akara/nodes/2003-01-01/4suite-section For the files, see: ftp://ftp.4suite.org/pub/4Suite/ Sources: ftp://ftp.4suite.org/pub/4Suite/4Suite-1.0a4.tar.gz Windows installer: ftp://ftp.4suite.org/pub/4Suite/4Suite-1.0a4.win32-py2.2.exe ftp://ftp.4suite.org/pub/4Suite/4Suite-1.0a4.win32-py2.3.exe ftp://ftp.4suite.org/pub/4Suite/4Suite-1.0a4.win32-py2.4.exe Windows zip: ftp://ftp.4suite.org/pub/4Suite/4Suite-1.0a4.zip You can also get the files on Sourceforge: https://sourceforge.net/projects/foursuite/ https://sourceforge.net/project/showfiles.php?group_id=39954 Documentation: In the locations specified above, with filenames of the form 4Suite-docs-1.0a4.* Highlights of changes -- This release has been extremely an long time in coming, and a great number of changes have come about. I'll try my best to summarize: * Python 2.2.1 is now the minimum required version * Feature enhancements for the domlettes, including - Ability to control encoding for parse - Ability to parse from general entities (i.e. multiple root elements) - .xpath() convenience method on nodes * Feature enhancements for the repository, including - MySQL driver - Flat File driver is no longer flat (now uses native directories) - Repository / Driver API restructured - ftss: URI scheme used throughout * Feature enhancements for Versa, including - Versa functions to control query scoping * Pruning of built-in XPath and XSLT extensions for consistency with EXSLT * Other API changes (mostly just name changes or adding optional functionality). Old names work, but are deprecated and trigger warnings * cDomlette is stable and FtMiniDom is deprecated. * Improvements to packaging and deployment * Numerous performance enhancements * Numerous bug fixes IMPORTANT alpha release notes -- If you have built a 4Suite repository using an older version of 4Suite, you will probably have to make adjustments for this new release. If you used 0.12.0a3, or a more recent version, then you will have to follow the migration instructions detailed in the following message: http://lists.fourthought.com/pipermail/4suite/2004-October/012933.html In general, it's worth being familiar with the following document: http://uche.ogbuji.net/tech/akara/nodes/2003-01-01/backup There have been on and off problems for Mac OS X users. Please see the following page for current status, notes and recommendations: http://uche.ogbuji.net/tech/akara/nodes/2003-01-01/osx Installation locations have changed on both Windows and Unix. See the current installation directory layout document at: http://4suite.org/docs/installation-locations.xhtml If there is a server config files at the default location for the build and platform (e.g. /usr/local/lib/4Suite/4ss.conf by default on UNIX), it will be renamed to 4ss.conf.old and then overwritten. For insulation from Domlette implementation changes, developers should always use the generic Ft.Xml.Domlette APIs (rather than, say Ft.Xml.cDomlette). -- Uche Ogbuji Fourthought, Inc. http://uche.ogbuji.net http://4Suite.org http://fourthought.com A hands-on introduction to ISO Schematron - http://www-106.ibm.com/developerworks/edu/x-dw-xschematron-i.html Schematron abstract patterns - http://www.ibm.com/developerworks/xml/library/x-stron.html Wrestling HTML (using Python) - http://www.xml.com/pub/a/2004/09/08/pyxml.html XML's growing pains - http://www.adtmag.com/article.asp?id=10196 XMLOpen and more XML Hacks - http://www.ibm.com/developerworks/xml/library/x-think27.html A survey of XML standards - http://www-106.ibm.com/developerworks/xml/library/x-stand4/

by frank＠niessink.com 19 Nov '04

19 Nov '04

I'm happy to announce the release of version 0.15 of Task Coach. This is the second public release and hopefully Task Coach is now more portable. Functionality is largely the same in comparison with the previous release. I'm specifically solliciting feedback on: 1) how portable is Task Coach? Can your run it on your platform, and if not, can you help me sort out the problem(s)? And 2) what features would you like to see included? Task Coach is a simple task manager that allows for hierarchical tasks, i.e. tasks in tasks. Task Coach is open source (GPL) and uses wxPython.

RELEASED Python 2.4, release candidate 1
by Anthony Baxter 19 Nov '04

19 Nov '04

On behalf of the Python development team and the Python community, I'm happy to announce the first release candidate of Python 2.4. Python 2.4c1 is a release candidate - we'd greatly appreciate it if you could download it, kick the tires and let us know of any problems you find, but it is probably not suitable for production usage. At this point, we're particularly interested in build bugs. If you could grab the source archive, build it and then run the test suite, we'd appreciate it. http://www.python.org/2.4 Notable changes in rc1 include a handful of bug fixes, including a thread shutdown race bug. See either the highlights, the What's New in Python 2.4, or the detailed NEWS file -- all available from the Python 2.4 webpage. This is the first release candidate of Python 2.4. Python 2.4 is now close to release - there should be few or no new features, merely bug fixes. Assuming no problems, we're looking at a final release around the end of November (if there are problems, there will be another release candidate). Please log any problems you have with this release in the SourceForge bug tracker (noting that you're using 2.4c1): http://sourceforge.net/bugs/?group_id=5470 Enjoy the new release, Anthony Anthony Baxter anthony(a)python.org Python Release Manager (on behalf of the entire python-dev team)

ANN: CherryTemplate-1.0.0 released
by remi＠cherrypy.org 18 Nov '04

18 Nov '04

Hello everyone, I'm happy to announce the first release of CherryTemplate, an easy and powerful templating system in python. Note that it is not "yet another templating system" because it used to be part of CherryPy, but is now released as a standalone package. Basically, you use it like this: $ python Python 2.3.3 (#51, Dec 18 2003, 20:22:39) [MSC v.1200 32 bit (Intel)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> from cherrytemplate import renderTemplate >>> name = "world" >>> renderTemplate('Hello, <py-eval="name"/>') 'Hello, world' The language only has a few tags: py-eval, py-exec, py-code, py-if, py-for, py-include but it is quite powerful because most of python's power is still available from the template: - "py-for" allows you to do things like <py-for="i,j in [(0,0), (1,2), (3,1)]"> - "py-code" allows you to insert full blocks of pure python code inside your template (it takes care of the indentation for you) CherryTemplate can also render external templates (ex: renderTemplate(file = 'template.html')) and has full unicode support. Once nice feature about it is that is uses generators to render your template, so if you need to process a large amount of data you can tell it to return a generator, and then you can loop through it. This way it doesn't use up too much memory. Here is an example: >>> template = '''<py-for="i in range(5)">i:<py-eval="str(i)"/></py-for>''' >>> result = renderTemplate(template, returnGenerator = True) >>> for res in result: print repr(res) 'i:' '0' 'i:' '1' 'i:' '2' 'i:' '3' 'i:' '4' >>> You can find more information (including the download link) on this page: http://trac.cherrypy.org/cgi-bin/trac.cgi/wiki/CherryTemplate Remi.
