ANN: PyEnchant 1.2.0
by Ryan Kelly 19 Sep '07

19 Sep '07

Hi All, I'm pleased to announce the release of PyEnchant version 1.2.0. This version includes some important updates in the underlying enchant library, and implements basic "filters" to allow skipping of email addresses, WikiWords, URLs, etc during a spellchecking session. Cheers, Ryan About: ------ Enchant (http://www.abisource.com/enchant/) is the spellchecking package behind the AbiWord word processor, is being considered for inclusion in the KDE office suite, and is proposed as a FreeDesktop.org standard. It's completely cross-platform because it wraps the native spellchecking engine to provide a uniform interface. PyEnchant brings this simple, powerful and flexible spellchecking engine to Python: http://pyenchant.sourceforge.net/ It also provides extended functionality including classes for tokenizing text and iterating over the spelling errors in it, as well as a ready-to-use text interface and wxPython dialog. Current Version: 1.2.0 Licence: LGPL with exemptions, as per Enchant itself ChangeLog for 1.2.0: -------------------- * Implemented "filters" that allow tokenization to skip common word forms such as URLs, WikiWords, email addresses etc. * Now ships with enchant-1.3.0, meaning: * PWLs can return a useful list of suggestions rather than the empty list * Hunspell replaces MySpell as the default Windows backend * Tokenization doesnt split words at non-alpha characters by default * GtkSpellCheckerDialog contributed by Fredrik Corneliusson * Removed deprecated functionality: * Dict.add_to_personal * All registry handling functionality from enchant.utils * enchant.utils.SpellChecker (use enchant.checker.SpellChecker) * Removed PyPWL, as native enchant PWLs can now suggest corrections -- Ryan Kelly http://www.rfk.id.au | This message is digitally signed.

Shed Skin Optimizing Python-to-C++ Compiler 0.0.10
by Mark Dufour 18 Jan '07

18 Jan '07

Hi all, I have just released version 0.0.10 of Shed Skin, an optimizing Python-to-C++ compiler. It allows for translation of pure (unmodified), implicitly statically typed Python programs into optimized C++, and hence, highly optimized machine language. Many non-trivial benchmarks (ray tracer, chess player, othello player, sat solver, 3 sudoku solvers..) run typically 2-40 times faster than when using Psyco, 12 times on average, and 2-220 times than when using CPython, 45 times on average. Besides many bug fixes, this release adds many error messages for unsupported features, so it should be much easier to try out the compiler and work around problems. Please download this new release from http://mark.dufour.googlepages.com and let me know about any problems/successes. Thanks, Mark Dufour. -- if vars: self.output('; '.join([self.type(var)+' '+name for (name,var) in vars.items()])+';')

py2exe 0.6.6 released
by Jimmy Retzlaff 31 Dec '06

31 Dec '06

py2exe 0.6.6 released ===================== py2exe is a Python distutils extension which converts Python scripts into executable Windows programs, able to run without requiring a Python installation. Console and Windows (GUI) applications, Windows NT services, exe and dll COM servers are supported. Changes in 0.6.6: * Better support for Python 2.5. * Experimental support for 64-bit builds of Python on win64. * Better ISAPI support. * New samples for ISAPI and COM servers. * Support for new "command-line styles" when building Windows services. Changes in 0.6.5: * Fixed modulefinder / mf related bugs introduced in 0.6.4. This will be most evident when working with things like win32com.shell and xml.xpath. * Files no longer keep read-only attributes when they are copied as this was causing problems with the copying of some MS DLLs. Changes in 0.6.4: * New skip-archive option which copies the Python bytecode files directly into the dist directory and subdirectories - no archive is used. * An experimental new custom-boot-script option which allows a boot script to be specified (e.g., --custom-boot-script=cbs.py) which can do things like installing a customized stdout blackhole. See py2exe's boot_common.py for examples of what can be done. The custom boot script is executed during startup of the executable immediately after boot_common.py is executed. * Thomas Heller's performance improvements for finding needed modules. * Mark Hammond's fix for thread-state errors when a py2exe created executable tries to use a py2exe created COM DLL. Changes in 0.6.3: * First release assembled by py2exe's new maintainer, Jimmy Retzlaff. Code changes in this release are from Thomas Heller and Gordon Scott. * The dll-excludes option is now available on the command line. It was only possible to specify that in the options argument to the setup function before. The dll-excludes option can now be used to filter out dlls like msvcr71.dll or even w9xpopen.exe. * Fix from Gordon Scott: py2exe crashed copying extension modules in packages. Changes in 0.6.2: * Several important bugfixes: - bundled extensions in packages did not work correctly, this made the wxPython single-file sample fail with newer wxPython versions. - occasionally dlls/pyds were loaded twice, with very strange effects. - the source distribution was not complete. - it is now possible to build a debug version of py2exe. Changes in 0.6.1: * py2exe can now bundle binary extensions and dlls into the library-archive or the executable itself. This allows to finally build real single-file executables. The bundled dlls and pyds are loaded at runtime by some special code that emulates the Windows LoadLibrary function - they are never unpacked to the file system. This part of the code is distributed under the MPL 1.1, so this license is now pulled in by py2exe. * By default py2exe now includes the codecs module and the encodings package. * Several other fixes. Homepage: <http://www.py2exe.org> Download from the usual location: <http://sourceforge.net/project/showfiles.php?group_id=15583> Enjoy, Jimmy

[ANN] Release 0.61.4 of Task Coach
by Frank Niessink 30 Dec '06

30 Dec '06

Hi all, Release 0.61.4 of Task Coach is a bug-fix release that hopefully fixes the following issues: * Make Task Coach work with Python 2.5. * Cancel reminders when marking a task completed. * Unchecking a reminder would cause an exception. * Column resizing is now less jumpy. * MSVCP71.DLL was missing from the Windows distribution. * Marking a task completed while completed tasks are hidden wouldn't immediately hide the completed task. * The category filter was not applied correctly on launch; showing categories as filtered but not hiding the associated tasks. * Turning on filtering for a category didn't mark the task file as changed. In addition, RPM and Debian distributions of Task Coach are now available. What is Task Coach? Task Coach is a simple task manager that allows for hierarchical tasks, i.e. tasks in tasks. Task Coach is open source (GPL) and is developed using Python and wxPython. You can download Task Coach from: http://www.taskcoach.org https://sourceforge.net/projects/taskcoach/ In addition to the source distribution, packaged distributions are available for Windows XP, Mac OSX, and Linux (Debian and RPM format). Note that Task Coach is alpha software, meaning that it is wise to back up your task file regularly, and especially when upgrading to a new release. Cheers, Frank

ANN: PyEnchant 1.3.0
by Ryan Kelly 29 Dec '06

29 Dec '06

Hi All, I'm pleased to announce the release of PyEnchant version 1.3.0. This version reverts the tokenization routines to their pre-1.2.0 behaviour, after several functionality regressions were reported. In the process it introduces some very minor API changes (hence the big version jump) which will affect users who directly create their own tokenization objects. The high-level interfaces - Dict, Broker, SpellChecker - have not changed since the 1.2.0 release. Cheers, Ryan About: ------ Enchant (http://www.abisource.com/enchant/) is the spellchecking package behind the AbiWord word processor, is being considered for inclusion in the KDE office suite, and is proposed as a FreeDesktop.org standard. It's completely cross-platform because it wraps the native spellchecking engine to provide a uniform interface. PyEnchant brings this simple, powerful and flexible spellchecking engine to Python: http://pyenchant.sourceforge.net/ It also provides extended functionality including classes for tokenizing text and iterating over the spelling errors in it, as well as a ready-to-use text interface and wxPython dialog. Current Version: 1.3.0 Licence: LGPL with exemptions, as per Enchant itself ChangeLog for 1.3.0: -------------------- * Re-worked the tokenization API to allow filters but still remove non-alpha-numeric characters from words by default. This introduces some minor backward-incompatabilities to the API: * 'fallback' argument to get_tokenizer() was removed, just catch the Error and re-try with whatever is appropriate for your application. * filters should be passed into get_tokenizer() as the second argument, rather than applied as seperate functions. * Basic whitespace-and-punctuation tokenization seperated from the language-specific parts. * Internal details of Filter classes expanded and generalized * English tokenization rules reverted to 1.1.5 version -- Ryan Kelly http://www.rfk.id.au | This message is digitally signed.

FlightFeather Social Networking Platform + site for office politics, etc.
by George Belotsky 29 Dec '06

29 Dec '06

FlightFeather's goal is "social networking for everyone". This means that *anyone* should have a chance to run a *popular* social networking site -- on minimal hardware, and without wasting bandwidth. Although the project is in its early stages, it is functional, and supports the "BoSStats" web application. BoSStats is a site dedicated to improving the world of work: you can discuss what makes a good boss, or share your experiences of office politics. You can also comment and vote on the posts made by others. The application does not set cookies, and no registration is required for anything except voting. http://www.bosstats.com/ Follow the "Platform" link on the above site to download the FlightFeather source code (released under the GPL). BoSStats is a good testbed for FlightFeather, and has value of its own, since meaningful advice about work-related problems is very hard to find. A "Wisdom of Crowds" solution -- particularly with strong privacy protection (see below) -- is a necessary addition to this field. The major design focus for FlightFeather are responsiveness and performance; the system should eventually support very high traffic volumes. In addition, FlightFeather allows for a great deal of user privacy -- a critical, rapidly emerging problem in the social networking realm. FlightFeather's most important feature is that all write requests generate (or modify) HTML files. In consequence, a pure read (the most common operation) merely serves static pages. This architecture strongly favors the use of Python, because of the complex logic required to manipulate an entire tree of text files. Expressing this logic clearly and succinctly is the key to maintainability of the code. The Python 2.5 "with" statement has proved to be particularly valuable for FlightFeather development. The implementation started with Python 2.4, and switched to Python 2.5 once that release became stable. Rewriting parts of FlightFeather using the "with" statement immediately simplified the system's file handling logic. This feature alone is reason enough to use Python 2.5. Everyone feel free to try out FlightFeather/BoSStats, and give me feedback either on the site itself, or by email. You can post any appropriate content to the site, as the system is live. Best Wishes for the Holidays, George Belotsky
