ctypes
by Thomas Heller 07 Nov '02

07 Nov '02

ctypes is a module allowing to create and manipulate C data types in Python. These can then be passed to C-functions loaded from dynamic link libraries. This module is supposed to be a greatly enhanced and much more complete replacement of Sam Rushing's calldll/npstruct/windll modules. ctypes is not based on Sam's work, it has different roots. It requires Python 2.2 or higher, since it makes intensive use of the new type system. ---- It provides classes which can be used to create complicated C data types, for example, those used in Windows type libraries. Included is a facility to dynamically load DLLs, retrieve functions, and call them. You can also call methods on COM objects. Implemented are simple data types (int, char, string, and so on), function pointers (callbacks), structures, unions, arrays, and pointers. ctypes uses win32 structured exception handling, to make it as safe as possible, although it is clear that it's easy to crash the Python interpreter. The source distribution contains an extensive, although inclomplete, tutorial (which you can also read online), as well as example scripts demonstrating the use. One of these scripts contains a dynamic Dispatch implementation, which is used to drive MS word as an example. ---- ctypes is not yet complete, this is an early release, but IMO it is already entirely usable. Just don't be too astonished if later versions have a different behaviour or api.

SC-Track Roundup 0.5.2 - an issue tracking system
by Richard Jones 06 Nov '02

06 Nov '02

================================================= SC-Track Roundup 0.5.2 - an issue tracking system ================================================= This is a bugfix release for version 0.5.x - if you're upgrading from before that, you *must* read doc/upgrading.txt! Unfortunately, the Zope frontend for Roundup is currently broken, with no fix in the forseeable future. Roundup requires python 2.1.3 or later for correct operation. Users of the sqlite backend are encouraged to upgrade sqlite to version 2.7.3. We've had a good crack at bugs (thanks to all who contributed!): - added quotes around python interpreter in windows bat (sf bug 623963) - fixed link at end of installation doc (sf bug 623957) - handle "classname" URL path errors cleaner (generate a 404) - added CGI :remove:<propname> and :add:<propname> which specify item ids to remove / add in <propname> multilink. - bugfix in boolean templating - remember the change note on bad submissions (sf bug 625989) - highlight required form fields (sf bug 625989) - force non-word boundary to match re: in subject (sf bug 626303) - handle sqlite bug (<2.7.2) (sf bug 630828) - handle missing props in anydbm stringFind - updated email package address formatting (deprecation) - copied email address quoting from email v2.4.3 so we're consistent with 2.2 - email summary extraction now takes the first whole sentence or line - whichever is longer - documented dependency on Active State (sf bug 623959) - ensured there's no zero-length files in source (sf bug 633622) - added ID to the search page (sf bug 631601) - fixed filtering by id in anydbm - show issue ID in the headings (sf bug 631598) - show entire messages by default in issues (sf bug 625995) - fixed journalling to save old values instead of new (sorry I took so long, GM) - handle missing REQUEST_URI for cgi-bin users (sf bug 620163) Source and documentation is available at the website: http://roundup.sourceforge.net/ Release Info (via download page): http://sourceforge.net/projects/roundup Mailing lists - the place to ask questions: http://sourceforge.net/mail/?group_id=31577 About Roundup ============= Roundup is a simple-to-use and -install issue-tracking system with command-line, web and e-mail interfaces. It is based on the winning design from Ka-Ping Yee in the Software Carpentry "Track" design competition. Note: Ping is not responsible for this project. The contact for this project is richard(a)users.sourceforge.net. Roundup manages a number of issues (with flexible properties such as "description", "priority", and so on) and provides the ability to: (a) submit new issues, (b) find and edit existing issues, and (c) discuss issues with other participants. The system will facilitate communication among the participants by managing discussions and notifying interested parties when issues are edited. One of the major design goals for Roundup that it be simple to get going. Roundup is therefore usable "out of the box" with any python 2.1+ installation. It doesn't even need to be "installed" to be operational, though a disutils-based install script is provided. It comes with two issue tracker templates (a classic bug/feature tracker and a minimal skeleton) and six database back-ends (anydbm, bsddb, bsddb3, sqlite, metakit and gadfly).

ANNOUNCE: Kiwi 0.5.0
by Christian Reis 05 Nov '02

05 Nov '02

I'm releasing today version 0.5.0 of Kiwi, a framework for developing graphical applications using Python and based on PyGTK. This is the sixth public release of Kiwi, and in this version it has evolved into a quite complete application framework, with many perks and niceties. Grab the latest code from: http://www.async.com.br/projects/kiwi/ If you are looking for something to make Python applications using GTK *much* easier to code, more Python-like, and with extended widget functionality, try Kiwi. This release adds a complete development guide and API documentation (generated with Edward Loper's excellent epydoc tool), the guide itself providing a lot of information on Kiwi development: http://www.async.com.br/projects/kiwi/howto/ Kiwi is used in Stoq (www.stoq.com.br), a GPLed retail system that is based on Python and PyGTK, and for internal development at SecurePipe, Inc. (www.securepipe.com). Kiwi is free software licensed through the GNU LGPL. Features include: - MVC-like base classes to structure an application into logical modules, including a Visual Proxy, Delegates and traditional Views and Controllers. - Full, transparent support for libglade, allowing UI development to be done graphically, and keeping implementation inside your instance of the framework. - Automatic signal connection based on function names; no need to connect() manually or use Glade's signal interface - Enhanced CList, CTree, OptionMenu, Label and Combo classes based on the related PyGTK widgets. - A complete development guide, and complete API documentation. - Examples and tests, and lots of code. This update provides: - Complete API documentation and a detailed guide full of examples and screenshots. - Proxy and Model classes, that provide a way to attach an instance to an interface and have it be instantly updated without requiring any extra coding. This is a very special feature that apps *much* easier to code. - CListDelegate, a configurable CList that provides a very high-level API for listing instances and configuring the CList width, visibility, alignment, tooltips and more. - We now have Delegate classes (combined Views and Controllers) that provide even more simplified ways to create interfaces. - The Kiwi license has been changed to LGPL in preparation for the first major release. - Serious optimizations to CList reordering. - Lots of code cleanup and refactoring. - Docstrings for all public methods and classes. - Over 15 example programs and 17 different tests. - Meaningless statistics: Diff changes: +16049/-11521; Checkins: 522; LOC: 4520(raw), 2429(sloc) 11 modules, 31 classes, 278 methods Many thanks to Jon Nelson, Ricardo Froehlich and Johan Dahlin for helping out with this version; lots of regression testing, suggestions and code examples were contributed by them. Kiwi Homepage: http://www.async.com.br/projects/kiwi/ Online documentation: HOWTO: http://www.async.com.br/projects/kiwi/howto/ API reference: http://www.async.com.br/projects/kiwi/api/ Download Kiwi 0.5.0 from http://www.async.com.br/projects/kiwi/dl/Kiwi-0.5.0.tar.gz We have Bonsai and Bugzilla available for Kiwi: http://bonsai.async.com.br/ http://bugs.async.com.br/ Feedback can come directly to me, kiko(a)async.com.br, or through the PyGTK list, pygtk(a)daa.com.au If you are using Kiwi in your project, it would be really nice to drop me a line and let me know, I would like to add a list to the homepage but I don't know most of you :) I know I promised this the last time, but development focus shifted to the framework and documentation; this means there is still no validated Entry. The next major release will include a reworked Entry widget that offers right-alignment (contributed by Johan) and validation. This work has progressed nicely but is still not quite ready, so I chose to leave it out for now. Take care, -- Christian Reis, Senior Engineer, Async Open Source, Brazil. http://async.com.br/~kiko/ | [+55 16] 261 2331 | NMFL

MacPython 2.2.2 is available
by Jack Jansen 01 Nov '02

01 Nov '02

MacPython 2.2.2 is available via <http://www.cwi.nl/~jack/macpython.html>. This release should be fully backward compatible to 2.2.1 (and 2.2). Aside from the 120 or so machine-independent bug fixes there are two important Mac-specific fixes: - MacPython now installs and runs on Jaguar (Mac OS X 10.2) - the occasional refusal of Python to run (showing only a <<terminated>> window) has been fixed. -- - Jack Jansen <Jack.Jansen(a)oratrix.com> http://www.cwi.nl/~jack - - If I can't dance I don't want to be part of your revolution -- Emma Goldman -

Python-DSV 1.3.6
by Cliff Wells 01 Nov '02

01 Nov '02

Version 1.3.6 of Python-DSV is available http://python-dsv.sourceforge.net/ This is mostly a bugfix release. Several um, unique arrangements of CSV data are now handled (hopefully) gracefully. This involved replacing a central portion of DSV.py, so bug reports are welcome. What is it? Python-DSV is a Python module that imports and exports CSV files. It is unique in that it has heuristics for determining the format of the file being imported. It also has an optional wxPython dialog for user interaction. It is pure Python so it should be very portable. Regards, Cliff
