[ANN] mode.py 1.0a1
by Chad Whitacre 07 Nov '06

07 Nov '06

Greetings, program! This is to announce the first public release of mode.py, a small utility module that models the life-cycle of an application as a series of four modes: debugging, development, staging, and production. Quick start: $ easy_install mode.py ... $ python ... >>> import mode >>> mode.development # the default True >>> mode.set('production') >>> mode.staging_or_production True >>> The mode is taken from the PYTHONMODE environment variable. A more illustrative example: import mode if mode.DEVELOPMENT_OR_DEBUGGING: db = "mysql://localhost:3306/test" elif mode.STAGING: db = "mysql://dbserver:33000/staging" elif mode.PRODUCTION: db = "mysql://dbserver:33000/live" For full documentation and downloads, see the project homepage: http://www.zetadev.com/software/mode.py/ Thanks. yours, Chad Whitacre http://www.zetadev.com/

[ANN] Movable Python 2.0.0 Beta 2
by Fuzzyman 07 Nov '06

07 Nov '06

I'm pleased to announce the release of `Movable Python 2.0.0 Beta 2 <http://www.voidspace.org.uk/python/movpy/>`_. There are now updated versions for Python 2.2 - 2.5, the Mega-Pack [#]_, and the free trial version. The most important changes in this release are : * Fixes for Pythonwin. The 'run' button and 'grep' dialog now work. * You can now specify a directory for config files. * The environment programs are run in is no longer pre-populated with variables. The **Movable Python** variables are now in a module called ``movpy``. You can see the full `changelog <http://www.voidspace.org.uk/python/movpy/changelog.html>`_ below. You can download the updated version from : `Movable Python Download Pages <http://voidspace.tradebit.com/groups.php>`_ You can get the free trial version, from `Movable Python Demo & Other Files <http://www.tradebit.com/usr/voidspace/files.php/7007>`_ What is Movable Python ================== **Movable Python** is a distribution of Python, for Windows, that can run without being installed. It means you can carry a full development environment round on a USB stick. It is also useful for testing programs with a 'clean Python install', and testing programs with multiple versions of Python. The GUI program launcher makes it a useful programmers tool, including features like : * Log the output of all Python scripts run * Enable Psyco for all scripts * Quick Launch buttons for commonly used programs * Configure multiple interpreters for use from a single interface It comes with the Pythonwin IDE. Plus many other features and bundled libraries. What's New ? ========== The changes in version 2.0.0 Beta 2 include : (Many thanks to Schipo and Patrick Vrijlandt for bug reports, fixes and suggestions.) Updated to Python 2.4.4 and wxPython 2.7.1 Fixed the bug with pylab support. Fixed problem with global name scope in the interactive interpreter. Everything moved out of the default namespace and moved into a module called 'movpy'. This contains : * ``filename`` = the path to the script we are running (the executable in interactive mode) * ``filedir`` = the directory that script is in (None when in interactive mode) * ``movpydir`` = the directory of the movpy executable * ``curdir`` = the cwd from which we have been called * ``configdir`` = the directory where config files are accessed from * ``libdir`` = the 'lib' directory that modules/packages are contained in * ``commandline`` != '' if '-c' was used * ``go_interactive`` = True if '-i' was set. * ``interactive`` = True if we are in an interactive session * ``interactive_mode`` is a function to enter interactive mode ``interactive_mode(localvars=None, globalvars=None, IPOFF=False, argv=None)`` * ``movpyw`` = True if we are running under movpyw rather than movpy The docs menu option will now launch the local version if available. Logfile is now closed using 'atexit' (should be closed *after* other 'atexit' functions finish). Logfile is flushed after every write to keep it in sync. A new command line option to specify the config file directory. ``movpyw --config ~\movpyfiles\config`` (The '~' is expanded to mean the user directory.) Fix for grep in Pythonwin IDE. Fix so that 'run' works in Pythonwin. (Browse button is disabled.) .. [#] The `Mega-Pack <http://www.voidspace.org.uk/python/movpy/megapack.html>`_ is all the interpreters bundled together. It comes pre-configured so that you can test programs with any version of Python (including IronPython) from a single interface.

ChiPy (Special) Meeting, Tuesday 14th 5:30 pm.
by bray＠sent.com 07 Nov '06

07 Nov '06

NOTE: This is a special meeting on next Tuesday in addition to our normal Thursday meeting. Attend both, if you can. Tuesday. November 14 2006. 5:30 pm. Topics ------ Ed Leaf on Dabo is an open-source framework for developing desktop (i.e., rich client) applications in Python. Details ======= Dabo is an open-source framework for developing desktop (i.e., rich client) applications in Python. Its primary target is the group of developers who come from a background in the proprietary Microsoft-centric tools, such as Visual FoxPro and Visual Basic, but it also targets Delphi, Filemaker, and other desktop application development systems who want rich client applications that run unmodified on Windows, Linux and OS X. The focus of the talk will be on the visual tools available in Dabo to help you quickly develop serious database applications in Python. Parts of the talk will also be directed toward existing wxPython developers who love the results of working with that UI toolkit, but who hate the non-Pythonic interface. Location -------- Monadnock Building at 53 W. Jackson in downtown Chicago: Conference Room 826. Alternatively, if we need more space, we will relocate to the restaurant on the first floor: http://www.cavanaughschicago.com. We will leave a note with the gaurd in case we relocate. RSVP to carl at personnelware.com Stay tuned to the mailing list for more details. http://mail.python.org/mailman/listinfo/chicago About ChiPy ----------- ChiPy is a group of Chicago Python Programmers, l33t, and n00bs.

ANN: PyQt v4.1 Released
by Phil Thompson 05 Nov '06

05 Nov '06

Riverbank Computing is pleased to announce the release of PyQt v4.1 available from http://www.riverbankcomputing.co.uk/pyqt/. The highlights of this release include: - support for Qt v4.2 including QGraphicsView and related classes, the undo framework, widget stylesheets, and integration with GNOME (both visually and the event loop) - the addition of the QtTest module for automated GUI testing - the addition of the QAxContainer module for Windows for integrating ActiveX controls. PyQt is a comprehensive set of Qt bindings for the Python programming language and supports the same platforms as Qt (Windows, Linux and MacOS/X). Like Qt, PyQt is available under the GPL and a commercial license. See http://www.riverbankcomputing.com/Docs/PyQt4/html/classes.html for the class documentation. PyQt v4 supports Qt v4 (http://www.trolltech.com/products/qt/index.html). PyQt v3 is still available to support earlier versions of Qt. PyQt v4 is implemented as a set of 10 extension modules containing approximately 400 classes and 6,000 functions and methods. QtCore The non-GUI infrastructure including event loops, threads, i18n, Unicode, signals and slots, user and application settings. QtGui A rich collection of GUI widgets. QtNetwork A set of classes to support TCP and UDP socket programming and higher level protocols (eg. HTTP). QtOpenGL A set of classes that allows PyOpenGL to render onto Qt widgets. QtSql A set of classes that implement SQL data models and interfaces to industry standard databases. Includes an implementation of SQLite. 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. QtXML A set of classes that implement DOM and SAX parsers. QtAssistant A set of classes that enables the Qt Assistant online help browser to be integrated with an application. QAxContainer A set of classes for Windows that allows the integration of ActiveX controls and COM objects. A Windows installer is provided for the GPL version of PyQt to be used with the GPL version of Qt v4 (http://www.trolltech.com/download/qt/windows.html). It enabes a complete PyQt environment to be installed on Windows without the need for a C++ compiler. PyQt includes the pyuic 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. Phil

ANN: SIP v4.5 Released
by Phil Thompson 05 Nov '06

05 Nov '06

Riverbank Computing is pleased to announce the release of SIP v4.5 available from http://www.riverbankcomputing.co.uk/sip/. SIP is a tool for generating Python modules that wrap C or C++ libraries. It is similar to SWIG. It is used to generate PyQt and PyKDE. Full documentation is available at http://www.riverbankcomputing.com/Docs/sip4/sipref.html. SIP is licensed under the Python License and runs on Windows, UNIX, Linux and MacOS/X. SIP requires Python v2.3 or later. The main focus of this release is support for Python v2.5. Other features of SIP include: - extension modules are implemented as a single binary .pyd or .so file (no Python stubs) - support for Python new-style classes - generated modules are quick to import, even for large libraries - support for Qt's signal/slot mechanism - thread support - the ability to re-implement C++ abstract and virtual methods in Python - the ability to define Python classes that derive from abstract C++ classes - the ability to spread a class hierarchy across multiple Python modules - support for C++ namespaces - support for C++ exceptions - support for C++ operators - an extensible build system written in Python that supports over 50 platform/compiler combinations - the generation of API files for IDEs that support autocompletion and call tips.

ANN: bridge 0.1.0 a general Python and IronPython XML library
by Sylvain Hellegouarch 04 Nov '06

04 Nov '06

Hi all, I'm happy to introduce the first release of bridge. A general purpose XML library for Python and IronPython (and ultimately Jython). bridge is very simple and light. It basically let you load an XML document via a set of different parsers (xml.dom, Amara, lxml, System.Xml) 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). == Download == * easy_install -U bridge * Tarballs http://www.defuze.org/oss/bridge/ * svn co https://svn.defuze.org/oss/bridge/ == Documentation == http://trac.defuze.org/wiki/bridge Hope this will help a few people in working with XML without worrying on which engine they choose to use. Have fun, -- Sylvain Hellegouarch http://www.defuze.org
