Shed Skin Optimizing Python-to-C++ Compiler 0.0.19
by Mark Dufour Feb. 8, 2007

Feb. 8, 2007

Hi all, I have just released version 0.0.19 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. This latest release adds basic support for iterators and generators, as well as a full implementation of the random module (by converting it to C++ from a Python implementation), among other things. For more details, please visit the homepage at: http://mark.dufour.googlepages.com Thanks! Mark Dufour. -- "One of my most productive days was throwing away 1000 lines of code" - Ken Thompson

Partial 1.0 - Partial classes for Python
by "Martin v. Löwis" Feb. 7, 2007

Feb. 7, 2007

I'm happy to announce partial 1.0; a module to implement partial classes in Python. It is available from http://cheeseshop.python.org/pypi/partial/1.0 A partial class is a fragment of a class definition; partial classes allow to spread the definition of a class over several modules. One location serves as the original definition of the class. To extend a class original_module.FullClass with an additional function, one writes from partial import * import original_module class ExtendedClass(partial, original_module.FullClass): def additional_method(self, args): body more_methods This module is licensed under the Academic Free License v3.0. Please send comments and feedback to martin(a)v.loewis.de

ANNOUNCE: PyGTK 2.10.4
by Johan Dahlin Feb. 5, 2007

Feb. 5, 2007

I am pleased to announce the stable version 2.10.4 of the Python bindings for GTK. The new release is available from ftp.gnome.org and its mirrors as soon as its synced correctly: http://ftp.gnome.org/pub/GNOME/sources/pygtk/2.10/ Blurb: GTK is a toolkit for developing graphical applications that run on systems such as Linux, Windows and MacOS X. It provides a comprehensive set of GUI widgets, can display Unicode bidi text. It links into the Gnome Accessibility Framework through the ATK library. PyGTK provides a convenient wrapper for the GTK+ library for use in Python programs, and takes care of many of the boring details such as managing memory and type casting. When combined with PyORBit and gnome-python, it can be used to write full featured Gnome applications. Like the GTK+ library itself PyGTK is licensed under the GNU LGPL, so is suitable for use in both free software and proprietary applications. It is already in use in many applications ranging from small single purpose scripts up to large full features applications. What's new since 2.10.3 ? - Documentation build fixes (John Finlay, Gustavo) - Return NULL on error in TextBuffer.register_serialize_format (Paolo Borelli) - Do not overwrite sys.argv (JP Calderone) - Add status icon example (Nikos Kouremenos) - Make it possible to remove rows in the gtk.TreeModel.foreach callback (Gustavo) - Code generator fix for %define (#381389, Manish Singh) - Duplicate GdkEvent.string member when setting it (#382428, Gustavo, John Ehresman) - Make it possible to use automake 1.10 (Kjartan Maraas) - distutils build fixes (#385934, Sebastien Bacher, Michael Bienia) - Allow None to be passed into gdk.Display (Johan) - Undeprecate gtk.container_class_list_child_properties (Johan) - Fix memory leak in gtk.Container.child_get (Gian Mario Tagliaretti) PyGTK requires GTK+ >= 2.8.0 and Python >= 2.3.5 to build. Bug reports, as always, should go to Bugzilla; check out http://pygtk.org/developer.html and http://pygtk.org/feedback.html for links to posting and querying bug reports for PyGTK. -- Johan Dahlin jdahlin(a)async.com.br

ANN: bridge 0.2.4
by Sylvain Hellegouarch Feb. 5, 2007

Feb. 5, 2007

Hi all, I am pleased to announce the release of bridge 0.2.4, a general purpose XML library for Python and IronPython. == Overview == bridge is very simple and light. It basically let you load an XML document via a set of different parsers (xml.dom, expat, Amara, lxml, System.Xml and ElementTree) and creates a tree of Elements and Attributes before releasing the parser resources. This means that once the document is loaded it is independent from the underlying parser. bridge then provides a straightforward interface to navigate through the tree and manipulate it. bridge does not try to replace underlying XML engines but offer a common API so that your applications are less dependent of those engines. bridge offers a couple of other goodies however to play with the tree of elements (see the documentation). == What's new? == This release is an important milestone for bridge: * added expat parser (seems to be the fatest parser bridge has) * many namespace issues fixed with the default parser * added incremental parsing with dispatching based on rules during the parsing of bridge Elements * added path lookup support (not XPath) * slightly increased the API of a few helps functions == TODO == Potentially the IronPython implementation is not as up-to-date as the other parsers. All parsers will generate the same bridge structure. The only minor difference at the present time is coming from the lxml parser which does not preserve processing instructions and comments before the root element. bridge cannot therefore access them. Add more unit tests. == Download == * easy_install -U bridge * Tarballs http://www.defuze.org/oss/bridge/ * svn co https://svn.defuze.org/oss/bridge/ == Documentation == Wiki: http://trac.defuze.org/wiki/bridge Have fun, -- Sylvain Hellegouarch http://www.defuze.org

ANN: Ophelia 0.2 - Create web sites from TAL templates
by Thomas Lotze Feb. 4, 2007

Feb. 4, 2007

Ophelia 0.2 was released today. Ophelia creates XHTML pages from templates written in TAL, the Zope Tag Attribute Language. It is designed to reduce code repetition to zero. At present, Ophelia contains a request handler for the Apache2 web server. Ophelia is released under the Zope Public License, version 2.1. To use Ophelia 0.2, you need: - Apache2 - Python 2.4 or better - mod_python 3.1 or better - the zope.tal package from Zope3 and anything it depends upon WSGI support is planned for a future version, possibly 0.3. The package is available from the Python package index as a source distribution and as eggs for both Python 2.4 and 2.5: <http://cheeseshop.python.org/pypi/Ophelia> You can access the source code repository at <https://svn.thomas-lotze.de/repos/public/Ophelia/>, browse it using ViewCVS at <http://svn.thomas-lotze.de/svn-public/Ophelia/>, or visit Ophelia's web page, containing a commented live usage example, at <http://www.thomas-lotze.de/en/software/ophelia/>. >From the documentation: What kind of sites is Ophelia good for? +++++++++++++++++++++++++++++++++++++++ Static content -------------- Consider Ophelia as SSI on drugs. It's not fundamentally different, just a lot friendlier and more capable. Use Ophelia for sites where you basically write your HTML yourself, except that you need write the recurring stuff only once. Reducing repetition to zero comes at a price: your site must follow a pattern for Ophelia to combine your templates the right way. Consider your site's layout to be hierarchical: there's a common look to all your pages, sections have certain characteristics, and each page has unique content. It's crucial to Ophelia that this hierarchy reflect in the file system organization of your documents; how templates combine is deduced from their places in the hierarchy of directories. Dynamic content --------------- Ophelia makes the Python language available for including dynamic content. Each template file may include a Python script. Python scripts and templates contributing to a page share a common set of variables to modify and use. Ophelia's content model is very simple and works best if each content object you publish is its own view: the page it is represented on. If you get content from external resources anyway (e.g. a database or a version control repository), it's still OK to use Ophelia even with multiple views per content object as long as an object's views don't depend on the object's type or even the object itself. Trying to use Ophelia on a more complex site will lead to an ugly entanglement of logic and presentation. Don't use Ophelia for sites that are actually web interfaces to applications, content management systems and the like. -- Viele Grüße, Thomas

About PyCamp - a Regional Python Unconference
by Jeff Rush Feb. 2, 2007

Feb. 2, 2007

A week or so ago, the Dallas and Houston Python User Groups met online in a chat room, to discuss the possibility of a regional Python conference. There was interest on all sides. Some of the Dallas members had recently attended their second BarCamp (http://barcamp.org), defined as an ad-hoc gathering born from the desire for people to share and learn in an open environment. From this interaction as well as the realization, after the Dallas group hosted PyCon in 2006 and will again in 2007, that a conference is a *lot* of work, we decided to try the idea of running an "unconference". An unconference (http://en.wikipedia.org/wiki/Unconference) is a conference where the content of the sessions is driven and created by the participants, generally day-by-day during the course of the event, rather than by a single organizer, or small group of organizers, in advance. And tossing around some names, we decided upon "PyCamp". There is much to be discussed re dates, location and how it will operate, so I set up the website: http://pycamp.python.org/ and a Mailman instance for mailing lists at: http://pycamp.python.org/lists/ The rough idea is to hold a Texas-wide unconference, perhaps sometimes in August and near Austin. There was also the idea of holding a rotating unconference that moves between Dallas, Austin and Houston, say twice a year. To minimize the impact on participant (not attendee - this is an unconference after all where you are expected to get involved) schedules, it was suggested we hold it over a weekend. We'd meet for dinner/drinks on a Friday evening, hold our talks at some hotel on Saturday and early Sunday, and then travel home Sunday evening. You'll notice that I keep saying "maybe", "suggested" and other weasel words above. This is because I'm not the conference chair (thankfully) and we're not imposing the schedule/rules. Ralph Green of Dallas has volunteered to wrangle the project and website, and is one of those who has attended a BarCamp. We need the creative energy and participation by members of all Python User Groups in Texas and invite you to join the Texas PyCamp mailing list (see above URL). Oh, and we didn't want to be the only ones having fun, so the PyCamp URL, wiki and mailing lists are available to other states or regions than Texas. Hopefully we can start a movement toward regional PyCamp Unconferences everywhere. If you're unfortunate enough to not live in Texas, drop me an email and I'll set you up your own regional section of the PyCamp site. Jump in and let's talk. And with PyCon rapidly approaching, we'd like to meet face-to-face with kindred spirits there. I'll make sure it gets on the conference schedule. Jeff Rush Python Advocacy Coordinator Dallas-Ft. Worth Pythoneers Coordinator PyCon 2007 Co-Chair

ANN: Paste 1.2
by Ian Bicking Jan. 31, 2007

Jan. 31, 2007

Paste 1.2 --------- I'm happy to release Paste 1.2. This release contains a mix of small features and bug fixes. This is only a release of core Paste (not Paste Script or Deploy), which contains the WSGI tools. What Is Paste? -------------- URL: http://pythonpaste.org Install: easy_install -U Paste News: http://pythonpaste.org/news.html Paste is a set of WSGI components, each of which can be used in isolation. But mixing them together leads to powerful chemical reactions which can be harnessed for good. These components let you do things like create applications that proxy to other websites, mount multiple applications under different prefixes, catch exceptions and interactively inspect the environment, and much more. Paste Deploy is a configuration system for these components. Paste Script is a jack of all trades that builds new project file layouts, runs WSGI server stacks, and does application deployment. Interesting News ---------------- See http://pythonpaste.org/news.html for details * Backward incompatible change in paste.fileapp.FileApp to make it support GET and HEAD properly. If you subclassed FileApp or DataApp you may need to change your code. * Parsing of Accept and Accept-Language * paste.wsgiwrappers.WSGIRequest can optionally decode unicode values in form submissions. * paste.httpserver supports all request methods (e.g., MKCOL), no longer blocks if you read past the end of wsgi.input, and includes code to control the thread pool and kill threads that are wedged. -- Ian Bicking | ianb(a)colorstudy.com | http://blog.ianbicking.org
