[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. Anyone using the eighteenth release is urge to upgrade immediately. The 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: 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.

ANN: python-ldap-2.0.5
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!
