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/

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.

python-dev Summary for 2004-10-01 through 2004-10-15
by Brett C. 18 Nov '04

18 Nov '04

This is a summary of traffic on the `python-dev mailing list`_ from October 01, 2004 through October 15, 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 fiftieth summary written by Brett Cannon (Time for my summary mid-life crisis). 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/2004-09-16_2004-09-30.html .. _original text file: http://www.python.org/dev/summary/2004-10-01_2004-10-15.ht ===================== Summary Announcements ===================== Sorry for the very late and short summary but I am in extreme crunch mode right now with school (partially thanks to a research paper comparing Python to Java) and preparing for applications to doctorate programs (any recommendations for schools with a good CS dept. and language research would be appreciated). Don't expect things to pick up again until the quarter is over (Dec. 9th is my last final). ========= Summaries ========= ---------------------- New module: subprocess ---------------------- Peter Ästrand wrote `PEP 324`_ to come up with a platform-independent way to create processes. Originally entitled popen5, it has now been added to the stdlib as subprocess. .. _PEP 324: http://www.python.org/peps/pep-0324.html Contributing threads: - `subprocess - updated popen5 module <http://mail.python.org/pipermail/python-dev/2004-October/049270.html>`__ - `python/dist/src/Lib subprocess.py,NONE,1.1 <http://mail.python.org/pipermail/python-dev/2004-October/049361.html>`__ - `Wither docs for the subprocess module? <http://mail.python.org/pipermail/python-dev/2004-October/049444.html>`__ -------------------- Python 2.4.b1 is out -------------------- `Python 2.4b1`_ has been released.

This quickly brought up the point that ConfigParser's API is not exactly optimal. So the decision was made to field new designs. If you happen to have your own code lying around that handles .ini files nicely then get it cleaned up and consider proposing at as a replacement. Some ideas have already been floated on the list but will have to wait for the next summary for mention/discussion.

16 Nov '04

Just released: the exciting Blender 2.35 version. Now with a full undo system, complete rewritten and upgraded mesh modeling, Outliner tool, new deform features, and much, much more... Read the full list of additions and changes in 2.35: http://www.blender3d.org/cms/Blender_2_35.482.0.html Here you can download Blender 2.35 for all platforms: http://www.blender3d.org/cms/Blender.31.0.html Blender homepage: http://www.blender.org Blender Python IDE: http://spe.pycs.net *** Changes in 2.35 Python API Scripts A new group was created to take care of bundled scripts management and discussions. Resources include mailing lists, a cvs repository and a section at Blender's wiki. The goal from now on is to make sure included scripts reach the quality and integration expected for any Blender functionality. For this release only two scripts were added to the already bundled ones: * Scripts Help Browser (Help menu): shows help information about registered scripts. This is a very recent addition, after 2.35 script authors will have time to update their scripts with more information. * Save Current Theme (Export menu): save the current theme as a Blender Python script. Internal changes BPython is going through general clean-up and internal restructuring of the code. Stephen Swaney has been very active in this area, besides having fixed many memory leaks and other bugs. Additions * new modules: Sound, Window.Theme; * script links: new scene OnSave event; * misc: now all command line arguments passed to Blender are available with sys.argv; * Blender: new options to Blender.Get(): 'homedir', 'scriptsdir', 'uscriptsdir'; * BGL: 6 GLU functions; * Effect: made Effect.Get('my_obj') return list with all my_obj's effects -- this breaks compatibility with its old behavior, but is in accordance with the rest of the API and is more useful; * Image: added image.glLoad() and image.glFree(); * Material: access to mirror and transparency; * Object: fixed obj.getMatrix(): defaults to world space again, added old pre-2.34 behavior as option: 'old_worldspace'; * Texture: access to Musgrave, Voronoi, Distorted Noise tex types; * Window: new GetPerspMatrix() function; * World: world.get/setCurrent() method. Contributors Besides the usual bpython team members, many other programmers contribute with patches, bug reports, suggestions and feedback via forums and mailing lists. We apologize for any omissions, please feel free to correct us: Stephen Swaney, Chris Keith, Joilnen B.

[ANNOUNCE] Nineteenth release of PythonCAD now available
by Art Haas 13 Nov '04

13 Nov '04

I'm pleased to announce the nineteenth 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 Python 2.3. 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. As of the sixteenth release, a Cocoa based front end is available for people on OS X having the Python/Objective-C bindings. Addition of other PythonCAD interfaces will depend on the availability of a Python module for that particular interface and developer interest and action. The nineteenth release of PythonCAD fixes a file saving bug found shortly after the eighteenth release was made public. The bug affected drawings that had text entities. A fix for this bug was found and tested by the bug reporter (thanks Ed Richley!) and confirmed to fix the problem. The serious nature of the bug called for making this new release. The only other change appearing in this release is the addition of the PostScript command 'showpage' appearing at the end of the generated plot file.

ANN: config module v0.3.4 released
by vinay_sajip＠yahoo.co.uk 11 Nov '04

11 Nov '04

A new version of the Python config module has been released. What Does It Do? ================ The config module allows you to implement a hierarchical configuration scheme with support for mappings and sequences, cross-references between one part of the configuration and another, the ability to flexibly access real Python objects, facilities for configurations to include and cross-reference one another, simple expression evaluation and the ability to change, save, cascade and merge configurations. You can easily integrate with command line options using optparse. This module has been developed on python 2.3 but should work on version 2.2 or greater. A test suite using unittest is included in the distribution. A very simple configuration file (simple.cfg): # starts here message: Hello, world! #ends here a very simple program to use it: from config import Config cfg = Config(file('simple.cfg')) print cfg.message results in: Hello, world! Configuration files are key-value pairs, but the values can be containers that contain further values. A simple example - with the example configuration file: messages: [ { stream : `sys.stderr` message: 'Welcome' name: 'Harry' } { stream : `sys.stdout` message: 'Welkom' name: 'Ruud' } { stream : $messages[0].stream message: 'Bienvenue' name: Yves } ] a program to read the configuration would be: from config import Config f = file('simple.cfg') cfg = Config(f) for m in cfg.messages: s = '%s, %s' % (m.message, m.name) try: print >> m.stream, s except IOError, e: print e which, when run, would yield the console output: Welcome, Harry Welkom, Ruud Bienvenue, Yves The above example just scratches the surface. There's more information about this module available at http://www.red-dove.com/python_config.html Comprehensive API documentation is available at http://www.red-dove.com/config/index.html As always, your feedback is most welcome (especially bug reports, patches and suggestions for improvement). Enjoy! Cheers Vinay Sajip Red Dove Consultants Ltd. Changes since the last release posted on comp.lang.python: ========================================================== Added ConfigInputStream to provide better Unicode support. Added ConfigReader.setStream(). Renamed config.get() to getByPath(), and likewise for ConfigList. Added Mapping.get() to work like dict.get(). Added logconfig.py and logconfig.cfg to distribution. Simplified parseMapping(). Allowed Config.__init__ to accept a string as well as a stream. If a string is passed in, streamOpener is used to obtain the stream to be used. Changed addNamespace/removeNamespace to make name specification easier. Refactored save(), added Container.writeToStream and Container.writeValue() to help with this.

by Michael Ströder 11 Nov '04

11 Nov '04

Find a new release of python-ldap: http://python-ldap.sourceforge.net/ python-ldap provides an object-oriented API to access LDAP directory servers from Python programs. It mainly wraps the OpenLDAP 2.x libs for that purpose. Additionally it contains modules for other LDAP-related stuff (e.g. processing LDIF, LDAPURLs and LDAPv3 schema). ---------------------------------------------------------------- Released 2.0.5 2004-11-11 Changes since 2.0.4: Some small improvements for SASL: The noisy output during SASL bind is avoided now. Interaction with output on stderr can be enabled by the calling application by explicitly defining SASL flags. Removed obsolete directory Win32/. Lib/: * Make sure that ldap.sasl.sasl.cb_value_dict is a dictionary even when the caller passes in None to argument cb_value_dict * Added new key-word arg sasl_flags to method LDAPObject.sasl_interactive_bind_s() Modules/: * l_ldap_sasl_interactive_bind_s(): New key-word arg sasl_flags passed to ldap_sasl_interactive_bind_s()

RPy to be distributed via Python-Announce-List@Python.Org
by Jain, Nitin 10 Nov '04

10 Nov '04

RPy to be distributed via Python-Announce-List(a)Python.Org What is RPy? -------------------- RPy is a very simple, yet robust, Python (http://www.python.org) interface to the R environment for statistical data analysis and graphics (http://www.r-project.org). RPy can manages translation between python and R formats for all kinds of R objects and can execute arbitrary R functions (including the graphic functions). All errors from the R language are converted to proper Python exceptions. All module installed on the R system are available from Python. Consequently, RPy allows Python programmers to easily add advanced statistical functionality to Python programs. It allows R programmers the ability to use Python to control R computations and to interface them with other systems. Examples include RSOAP (http://rsoap.sf.net), RSessionDA (http://research.warnes.net/projects/rzope/rsessionda), and RStatServer (http://rstatserver.sf.net). These products, which make heavy use of RPy have been used in a production environments for two years. New features in 0.4.0 ------------------------------- o Now works with R 2.0.0 o R header files for R 1.8.0 through R 2.0.0 are now included with rpy. This should make it easier to build. o All reported bugs have been fixed. For more information visit the RPy home page at http://rpy.sf.net, or the RPy SourceForge project page at http://www.sf.net/projects/rpy. ______________________ Nitin Jain, PhD Non Clinical Statistics Pfizer, Inc.

IMDbPY 1.4 released
by alberanid＠libero.it 10 Nov '04

10 Nov '04

IMDbPY 1.4 is available (tgz, deb, rpm) here: http://imdbpy.sourceforge.net/ IMDbPY is a Python package useful to retrieve and manage the data of the IMDb movie database. In this release, minor changes were introduced to stay up-to-date with the IMDb's web site and some bugs were fixed. 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 theoretically 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. So far the only data source supported is the IMDb web server. -- Davide Alberani <alberanid(a)libero.it> [PGP KeyID: 0x465BFD47] http://erlug.linux.it/~da/

ANNOUNCE: wxPython 2.5.3.1
by Robin Dunn 09 Nov '04

09 Nov '04

Announcing ---------- I'm pleased to announce the 2.5.3.1 release of wxPython, now available for download at http://wxPython.org/download.php What is wxPython? ----------------- wxPython is a GUI toolkit for the Python programming language. It allows Python programmers to create programs with a robust, highly functional graphical user interface, simply and easily. It is implemented as a Python extension module that wraps the GUI components of the popular wxWidgets cross platform library, which is written in C++. wxPython is a cross-platform toolkit. This means that the same program will usually run on multiple platforms without modifications. Currently supported platforms are 32-bit Microsoft Windows, most Linux or other Unix-like systems using GTK or GTK2, and Apple Macintosh OS X. Changes in 2.5.3.1 ------------------ For the complete list of changes in this release, please see http://wxPython.org/recentchanges.php. Some of the highlights are as follows: * It is now possible to install multiple versions of wxPython at the same time, and there is support for choosing at runtime which version will be imported with "import wx". See the Migration Guide and http://wiki.wxpython.org/index.cgi/MultiVersionInstalls for more details. * Added wx.lib.ogl.DrawnShape, and fixed various little bugs in the new OGL. * Added support to XRC and XRCed for the 3-state checkbox flags and also for wx.ToggleButton. Updated the generic window styles supported by XRCed. * It is now possible to create "stock" buttons by using one of the "stock" IDs. If the platform has coresponding standard button images then they will be used. * Added wx.lib.ticker.Ticker class from Chris Mellon. * Added wx.Frame.RequestUserAttention which, if the platform suports it, will do something (such as flash the task bar item) to suggest to the user that they should look at that window. * wx.Sizer.Show (and Hide) now take an optional parameter specifying if the item to be shown should be searched for recursivly in subsizers, and return a boolean value indicating if the item was found. * Added wx.Choicebook, yet another notebook-like control. * Added limited support for wxEventLoop. * wxMac: wx.TaskBarIcon is implemented by allowing you to change the app's icon on the Dock and also specifying a menu that should be merged with the normal dock popup menu. * FloatCanvas updates from Chris Barker * PyPlot updates from Gordon Williams. * MaskedEdit updates from Will Sadkin. * Added wrappers for wx.WebKitCtrl for the OSX build, from Kevin Ollivier. * wxPython on OSX can now be built in Unicode mode and comes with an uninstaller script. -- Robin Dunn Software Craftsman http://wxPython.org Java give you jitters? Relax with wxPython!
