ANNOUNCE: wxPython 2.9.3.0 (classic)
by Robin Dunn 28 Dec '11

28 Dec '11

Announcing ---------- wxPython 2.9.3.0 (classic) has been released and is now available for download at http://wxpython.org/download.php. Among other things, this build adds some classes produced by one of the Google Summer of Code projects, wx.html2.WebView and related classes. This gives wxPython the ability to embed a native HTML/CSS/JS renderer using the same API and events on all platforms. More details are below. Various binaries are available for 32-bit and 64-bit Windows, and also for OSX using the Carbon and Cocoa APIs, for Python 2.6 and 2.7. Source code is also available at http://wxpython.org/download.php of course, for building your own. 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 set of Python extension modules that wrap 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 and 64-bit Microsoft Windows, most Linux or other Unix-like systems using GTK2, and Mac OS X 10.4+. In most cases the native widgets are used on each platform to provide a 100% native look and feel for the application. Major changes in 2.9.3.0 ------------------------ wx.ListCtrl: Added a static method named HasColumnOrderSupport which returns a boolen value indicating if the column ordering APIs (see next item) are implemented for the current platform. Added methods for querying and manipulating the ordering of the columns (in wx.LC_REPORT mode only.) This is not implemented on all platforms so use HasColumnOrderSupport to find out if the APIs are supported. The new APIs are: GetColumnOrder, GetColumnIndexFromOrder, GetColumnsOrder and SetColumnsOrder. Added wrappers for new WebView classes which came from a successful Google Summer of Code project this year. This new module allows you to embed the platform's native HTML/CSS/Javascript rendering engine in a wx application like we've always been able to do with wx.webkit on Mac or with the various ActiveX modules that we've had for windows, except in the new version it uses the exact same API on all platforms and also provides an implementation for GTK. Currently on Windows the IE Trident engine is used, and WebKit is used on OSX and GTK. The code is organized to eventually allow alternate backend renderer implementations. The GTK version requires at least version 1.3.1 of libwebkitgtk-dev, which is the default on most of the recent Linux distributions. Please note that although these new classes and libraries are using names based on "WebView" I have put the wxPython verison of them in the wx.html2 module because the wxWebKit project already produces a wx.webview module for wxPython. The wx.lib.pubsub package has been updated to the latest verison and several examples have been added to the samples folder. -- Robin Dunn Software Craftsman http://wxPython.org

ANN: PyQt v4.9 Released (Python bindings for Qt)
by Phil Thompson 23 Dec '11

23 Dec '11

PyQt v4.9 has been released and is available from http://www.riverbankcomputing.com/software/pyqt/. PyQt is a comprehensive set of bindings for the Qt application and UI framework from Nokia. It supports the same platforms as Qt (Windows, Linux and MacOS/X). PyQt supports Python v3 and Python v2.3 and later. The highlight of this release is full support for Qt v4.8.0 and the inclusion of the QtDBus module (so providing support for DBus with Python v3). Windows installers are provided for the GPL version of PyQt which contains everything needed for PyQt development (including Qt, Qt Designer, QScintilla, and MySQL, PostgreSQL, SQLite and ODBC drivers) except Python itself. Installers are provided for the 32 and 64 bit versions of Python v2.5, v2.6, v2.7, v3.1 and v3.2. PyQt v4 is implemented as a set of 19 extension modules containing over 400 classes and over 6,000 functions and methods. QtCore The non-GUI infrastructure including event loops, threads, i18n, Unicode, signals and slots, user and application settings, mapped files and shared memory. QtDeclarative A set of classes that implement a framework for building highly dynamic user interfaces using the QML declarative language that can be integrated with Python. QtDBus A set of classes for accessing remote applications using the DBus protocol. QtDesigner A set of classes that allow the Qt Designer GUI design tool to be extended with PyQt. QtGui A rich collection of GUI widgets. QtHelp A set of classes for creating and viewing searchable documentation and being able to integrate online help with PyQt applications. It includes the C++ port of the Lucene text search engine. QtNetwork A set of classes to support TCP and UDP socket programming and higher level protocols (eg. HTTP, SSL). QtOpenGL A set of classes that allows PyOpenGL to render onto Qt widgets. QtScript A set of classes that implements a JavaScript interpreter. Python objects may be exposed in the interpreter as JavaScript objects. QtScriptTools A debugger for the JavaScript interpreter. QtSql A set of classes that implement SQL data models and interfaces to industry standard databases. The Windows installers include support for SQLite, MySQL, PostgreSQL and ODBC. QtSvg A set of classes to render SVG files onto Qt widgets. QtTest A set of classes to automate unit testing of PyQt applications and GUIs. QtWebKit This implements a web browser engine based on the WebKit engine used by Apple's Safari browser. It allows the methods and properties of Python objects to be published and appear as JavaScript objects to scripts embedded in HTML pages. QtXML A set of classes that implement DOM and SAX parsers. QtXMLPatterns A set of classes that implement XQuery and XPath support for XML and custom data models. QAxContainer A set of classes for Windows that allows the integration of ActiveX controls and COM objects. phonon A cross-platform multimedia framework that enables the use of audio and video content in PyQt applications. DirectX is used as the Windows backend, QuickTime as the MacOS/X backend, and GStreamer as the Linux backend. QtMultimedia A set of classes that provide low-level multimedia functions. Application developers would normally use the phonon module. PyQt includes the pyuic4 utility which generates Python code to implement user interfaces created with Qt Designer in the same way that the uic utility generates C++ code. It is also able to load Designer XML files dynamically. PyQt is available under the GPL and a commercial license. Unlike Qt, PyQt is not available under the LGPL. The commercial PyQt license allows GPL applications to be relicensed at any time.

python.net stackless.com moving days
by Christian Tismer 21 Dec '11

21 Dec '11

Hi friends, The python.net and stackless.com sites are moving again. I have upgraded from a EQ8 to an EX4 server, again from Hetzner, Germany. It has only 16GIB instead of 24, but a Core-I7 - 2600 CPU at 3.5 GHz and A 3 TB Raid1. That is double size and performance at a 2/3 reduced price - efficient! Unfortunately it involves some work, and a change of IP addresses. python.net 176.9.65.89 stackless.com 176.9.65.90 The transition will occur in a few days, for sure before 2012, because the contract is cancelled :-D I think it will be smooth. The hard stuff already happened during the last days, when I cleaned and upgraded with lots of problems to solve. The rest is almost a proper set of rsync-s and IP/DNS changes. This was the last word of the optimist. I will notify you on the day when DNS will chang gg ggge eeee /($)/&$@ krrrk -.;;; beep -..- ...---... ...---... ...---... ...--- CRC erroR BAD dump info, stackpointer lost/// ::: hänschen klein ging allein in die weeeeeeaaaaoooouuuuummmmp......

tox-1.3: virtualenv-based test run automizer
by holger krekel 21 Dec '11

21 Dec '11

tox 1.3: the virtualenv-based test run automatizer =========================================================================== I am happy to announce tox 1.3, containing a few improvements over 1.2. TOX automates tedious test activities driven from a simple ``tox.ini`` file, including: * creation and management of different virtualenv environments with different Python interpreters * packaging and installing your package into each of them * running your test tool of choice, be it nose, py.test or unittest2 or other tools such as "sphinx" doc checks * testing dev packages against each other without needing to upload to PyPI Docs and examples are at: http://tox.testrun.org/ Installation: pip install -U tox code hosting and issue tracking on bitbucket: http://bitbucket.org/hpk42/tox best, Holger Krekel 1.3 ----------------- - fix: allow to specify wildcard filesystem paths when specifiying dependencies such that tox searches for the highest version - fix issue21: clear PIP_REQUIRES_VIRTUALENV which avoids pip installing to the wrong environment, thanks to bb's streeter - make the install step honour a testenv's setenv setting (thanks Ralf Schmitt)

Elementwise -//- first release -//- Element-wise (vectorized) function, method and operator support for iterables in python.
by Nathan Rice 20 Dec '11

20 Dec '11

Elementwise provides a proxy object for iterables which supports chained method calls, as well as elementwise expressions and some built-in functions. Example: class ExampleList(ElementwiseProxyMixin, list): def __new__(cls, iterable): return list.__new__(cls, iterable) foo = ExampleList([1, 2, 3, 4]) # You could also do: efoo = ElementwiseProxy(foo) efoo = foo.each assert list(efoo.bit_length()) == [1, 2, 2, 3] print "bit length: ", list(efoo.bit_length()) assert list(efoo + 1) == [2, 3, 4, 5] print "with addition of 1: ", list(efoo + 1) assert list(efoo * 2) == [2, 4, 6, 8] print "with multiplication by 2: ", list(efoo * 2) assert list(efoo == 2) == [False, True, False, False] print "testing equality: ", efoo == 2 assert list((efoo + 1) * 2 + 3) == [7, 9, 11, 13] print "chaining addition and multiplication: ", (efoo + 1) * 2 + 3 Each ElementwiseProxy also has a "parent" attribute so you can backtrack in the chain as needed rather than store each intermediate value, if you think you might need them. There are still some issues with proper support of things like bool() and int(), which refuse to return things that are not of the correct type. Get it: PyPi: http://pypi.python.org/pypi/elementwise/0.111220 GitHub: https://github.com/nathan-rice/Elementwise This was developed as a proof of concept for expanding the role of element-wise syntax in python, and to that end I welcome comments.
