ANN: PyEnchant 1.2.0
by Ryan Kelly Sept. 19, 2007

Sept. 19, 2007

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 Jan. 18, 2007

Jan. 18, 2007

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()])+';')

Ann: FarPy GUIE v0.5.3
by dberlin＠gmail.com Nov. 30, 2006

Nov. 30, 2006

About http://farpy.holev.com GUIE (GUI Editor) provides a simple WYSIWYG GUI editor for wxWidgets. The program was made in C# and saves the GUI that was created to a XML format I called GUIML. This GUIML is a pretty standard representation of the GUI created with the program with some helpful additions for .NET. Next, GUIE takes these GUIML files and translates it to either wxPython Python code or wxRuby Ruby code (more languages in the future). You may ask yourself why I took the extra step? Why didn't I go straight from C# controls to wxPython code? Why is GUIML necessary? Well, it isn't. It is there simply for people (or maybe I) to take the GUIML and convert it to other languages. This, by effect can convert this tool from a Python GUI editor, to "any programming language with a GUI module" GUI editor. The GUI Editor was built to be as point & click as possible, trying to avoid wx's sizers completly. This means that controls can go anywhere, and you have the freedom to play with the GUI however you want. *new* GUIE goes Open Source - Source-Code now available for download! Changes (as of v0.5.3) Added: Support for different tab-types (space & real-tabes), see settings Fixed: Error when trying to export empty PictureBox Changed: Removed dotted background Fixed: Align to grid offset fix Added: Align to grid to settings file, now choice is saved Changes (as of v0.5.2) Added: IronPython GUI Support! (Microsoft .NET Windows Forms in Python) Changes (as of v0.5.1) Added: Drag & Drop functionality for adding controls Changed: Settings mechanism. "settings.opt" replacing "settings.xml". Fixed: Bug causing panel background color to be other than white Changes (as of v0.5) Added: Source release Added: Partial wxPerl support Fixed: Splash screen causes loading delay Fixed: When saving guiml, controls got a gray background-color Changed: Certain GUI improvements in settings form Fixed: Actions should be disabled when no form is open Changed: Logo in splash screen Fixed: XY Coords incorrect when hovering controls Added: Unicode support in guiml files http://farpy.holev.com

ANN: FileTrack 0.1-beta3 is released
by t.koutsovassilis＠gmail.com Nov. 30, 2006

Nov. 30, 2006

FileTrack is a Web-enabled communication log, keeping track of all of your company's inbound and outbound documents. It supports multiple logs, auto-archiving of older entries, and generates simple reports based on multiple criteria. One or more log entries, contacts, or documents can be grouped together into an issue for easier monitoring. This release of FileTrack is fully compatible with Porcupine v0.0.8. Moreover, it includes a few minor bug fixes and the UI has taken advantage of the new box layout QuiX widget, which has replaced the non-interactive splitters. This application is also a good sample for those willing to develop a Porcupine application, as it includes code for all of the three layers (custom schema, servlets and presentation) and all forms of servlets (PSP pages, XMLRPC and QuiX servlets). Installation instructions can be found at http://wiki.innoscript.org/index.php/Administrators/HowToInstallPPFiles Other available Porcupine applications can be downloaded from http://www.innoscript.org/component/option,com_remository/Itemid,33/func,se…

odict the Ordered Diction 0.2.2
by Fuzzyman Nov. 29, 2006

Nov. 29, 2006

After a break of almost a year there has been an update to `odict the Ordered Dictionary <http://www.voidspace.org.uk/python/odict.html>`_. The latest version is 0.2.2, with changes implemented by Nicola Larosa. Despite over 700 downloads since May (plus 1300 as part of `pythonutils <http://www.voidspace.org.uk/python/pythonutils.html>`_) there have been no bug reports, only improvements [#]_. {sm;:-)} * `Quick Download <http://www.voidspace.org.uk/cgi-bin/voidspace/downman.py?file=odict.py>`_ What is odict? ========== **odict** is a pure Python implementation of an ordered dictionary. It keeps keys in insertion order and allows you to change the order. Methods (including iteration) that would return members in an arbitrary order are now ordered. There is also the `SequenceOrderedDict <http://www.voidspace.org.uk/python/odict.html#sequenceordereddict>`_ that behaves like a sequence as well as a dictionary. It allows slicing and the keys, values and items methods are special sequence objects (which are also callable and so behave as methods too). What's New ? ========== Code ------- Removed the TODO and CHANGELOG sections in the tail docstring (they are in the docs anyway). Disabled warnings during tests. Explicitly disabled tests execution on Python v.2.2 . In addition to the slicing tests, other ones are failing. Removed code duplication between the ``__init__`` and the ``update`` methods. Misc. cleanup. Also, based on code from `Tim Wegener`_: - added the ``rename`` method; - removed a ``has_key`` usage in the ``__setitem__`` method. Documentation ---------------------- Moved the ISSUES chapter from code's tail docstring to here. Moved up the `Creating an Ordered Dictionary <http://www.voidspace.org.uk/python/odict.html#creating-an-ordered-dictionary>`_ chapter. Added prompts to the code examples and removed the superfluous print statements (sometimes they were there, sometimes they were not). Misc. cleanup. .. [#] So either no-one is using it, or it's really good...

itools 0.14.6 released
by "J. David Ibáñez" Nov. 28, 2006

Nov. 28, 2006

itools is a Python library, it groups a number of packages into a single meta-package for easier development and deployment: itools.catalog itools.http itools.uri itools.cms itools.i18n itools.vfs itools.csv itools.ical itools.web itools.datatypes itools.rss itools.workflow itools.gettext itools.schemas itools.xhtml itools.handlers itools.stl itools.xliff itools.html itools.tmx itools.xml The focus of this release is performance and bug hunting. First the speed: - Indexing of office documents (PDF, OpenDocument, Word, etc.) has been massively improved in both speed and memory usage. - The "get_handler" and "traverse2" methods (from itools.handlers) now accept the optional parameter "caching"; if set to False caching won't be active for this call, see #569 for the details. - The catalog has been optimized to be about 12% faster with the index and unindex operations. - The whole module "itools.i18n.oracle" (whose purpose is to guess the language of a text) has been rewritten for better performance and readibility. And now for the bugs: - A serious bug has been fixed in "itools.cms": under some conditions the catalog was not synchronized with the data. The issue was solved with an update of the catalog, but still very annoying. - Some bugs in itools.xhtml and itools.html have been fixed related to the the semi-automatic translation of (X)HTML templates and documents. And the unit tests have been updated. See #279 for the details. - Many bugs have been fixed in the itools.cms web interface: #294, #438, #512, #563, #576, #577, #578 and #579. Credits: - Luis Belmar-Letelier helped fixing bugs; - Hervé Cauwelier worked on the performance and fixed some bugs; - Nicolas Deram helped fixing bugs; - J. David Ibáñez helped with the performance and fixed many bugs.

DFW Pythoneers had a Successful Holiday Meeting
by Jeff Rush Nov. 27, 2006

Nov. 27, 2006

The DFW Pythoneers had a great meeting this past Saturday, with 8 people showing up on the holiday weekend. We discussed Python descriptors, properties and lazy/cached computation, and then went into an informal discussion about metaclasses and played with a simple example. The ideas we covered took a bit of effort to get your head around, but everyone seemed to appreciate their value when we wrapped up. For those that don't know, the more formal presentations for our club are archived at: https://dfwpython.org/repo/Presentations/ * 2005-07-17-Serving-Web-Content-using-Python/ * 2005-08-17-Storing-Data-using-Python/ * 2006-03-25-About-Python-Eggs.odt * 2006-03-25-About-Python-Eggs.pdf * 2006-06-24-Python-Design-Patterns.odt * 2006-06-24-Python-Design-Patterns.pdf * 2006-07-08-Python-Design-Patterns-2.odt * 2006-07-08-Python-Design-Patterns-2.pdf * 2006-07-08-Python-Design-Patterns-Handout.odt * 2006-08-12-Python-2.5.odt * 2006-08-12-Python-2.5.pdf * 2006-08-12-Python-Design-Patterns-3.odt * 2006-08-12-Python-Design-Patterns-3.pdf * 2006-11-25-FunWithDescriptors/ And we have a slowly growing set of club projects at the following page. Note however that many of them are experimental or unfinished, so don't expect polished ready-to-run source. https://dfwpython.org/repo/Projects/ * DBUS/ * GnomeApplets/ * HalResponder/ * MailClients/ * PongInvaders/ * PyCon/ * PyIE/ * TwistedAddressbook/ * TwistedBase/ * TwistedCalendar/ * TwistedTaskmaster/ * challenges/ * googlewhack/ * rpmcleaner/ Last, at a recent meeting I went over the infrastructure of the Python advocacy website I'm working on, written in Zope 3. Still a bit rough, for those who've asked, here is where you can find the source: https://svn.python.org/www/trunk/advocacy.python.org/ I hope to see you at a future meeting.
