Updated Cygwin Package (experimental): python-2.6.5-1
by Jason Tishler April 30, 2010

April 30, 2010

*** Attention Cygwin Python module package maintainers *** *** Cygwin is migrating from Python 2.5 to 2.6... *** New News: === ==== I have released Cygwin Python 2.6.5-1 as experimental. The tarballs should be available on a Cygwin mirror near you shortly. The main purpose of this release is to begin the transition to make Python 2.6 the official Cygwin version. If you are one of the Cygwin Python module package maintainers, then please take this opportunity to build, test, and change (if necessary) your package to support Python 2.6. Note the following: 1. 2.6.5-1 is experimental and 2.5.5-1 remains current. I will update Cygwin to make 2.6.5-1 (or later) current on or about June 1, 2010. 2. You need to select the 'Exp' radio button when running Cygwin's setup.exe to install 2.6.5-1. 3. If you install 2.6.5-1, then any 2.5 module will no longer work. Old News: === ==== Python is an interpreted, interactive, object-oriented programming language. If interested, see the Python web site for more details: http://www.python.org/ Please read the README file: /usr/share/doc/Cygwin/python.README since it covers requirements, installation, known issues, etc. Standard News: ======== ==== To update your installation, click on the "Install Cygwin now" link on the http://cygwin.com/ web page. This downloads setup.exe to your system. Then, run setup and answer all of the questions. If you have questions or comments, please send them to the Cygwin mailing list at: cygwin(a)cygwin.com . *** CYGWIN-ANNOUNCE UNSUBSCRIBE INFO *** If you want to unsubscribe from the cygwin-announce mailing list, look at the "List-Unsubscribe: " tag in the email header of this message.

oursql 0.9.2 released -- better mysql for python 2/3
by Aaron Gallagher April 28, 2010

April 28, 2010

oursql 0.9.2 has been released, making it now the only mysql driver for python that runs on python 3.x. For source, windows binaries, issue tracking, and basically everything, see https://launchpad.net/oursql oursql was basically written to work all-around better than MySQLdb. I'll get benchmarks up soonish showing that it's also generally more performant. From the documentation, here's a short list of reasons why you should use oursql over MySQLdb: * oursql has real parameterization, sending the SQL and data to mysql completely separately. * oursql allows text or binary data to be streamed into the database and streamed out of the database, instead of requiring everything to be buffered in the client. * oursql can both insert rows lazily and fetch rows lazily. * oursql has unicode support on by default, as well as making more of an effort to ensure that . * oursql supports python 2.4 through 3.1 without any deprecation warnings on 2.6+ (see PEP 218), without completely failing on 2.7 (see PEP 328), and without requiring the user to mess around with 2to3 on 3.x. * oursql is licensed under the BSD license.

[ANN] CubicWeb 3.8 released
by Sylvain Thénault April 28, 2010

April 28, 2010

CubicWeb 3.8.0 went out last week, but now we have tested it, produced a 3.8.1, it's show time! What's new in CubicWeb 3.8? One of the most important change is http server update to move from deadend twisted.web2 to twisted.web. With this change come the possibility to configure the maximum size of POST request in the configuration file (was hard-coded to 100Mo before). Other changes include: * CubicWeb should now be installable through **pip** or **easy_install**. This is still experimental, and we don't use it that much so please, give us some feedback! Some cubes are now also pipable (comment, blog...), but more will come with new releases. * .execute() function lost is cache key argument. This is a great news since it was a pain to explain and most cubicweb users didn't know how to handle it well (and I'm thre greatest beneficer since I won't have to explain over and over again) * nicer schema and workflow views * refactored web session handling, which should now be cleaner, clearer, hence less buggy... * nicer skeleton generation for new cubes, cleaner __pkginfo__ (you don't have to define both __depends__ / __depends_cubes__ or __recommends__ / __recommends_cubes__ in the general case, and other cleanups) Enjoy! -- Sylvain Thénault LOGILAB, Paris (France) Formations Python, Debian, Méth.

[ANN] pyjamas 0.7 released
by Luke Kenneth Casson Leighton April 25, 2010

April 25, 2010

pyjamas - the stand-alone python-to-javascript compiler, and separate GUI Widget Toolkit, has its 0.7 release, today. this has been much delayed, in order to allow the community plenty of time between the 0.7pre2 release and the final release, to review and test all the examples. pyjamas allows developers to create applications that will run either in any modern web browser (with no plugins required) or as a stand-alone cross-platform desktop application (like PyQT4 or PyGTK2), WITHOUT requiring modifications to the original python source. this concept is singularly unique in the free software python world, but is conceptually similar to Adobe AIR and Silverlight - without the massive plugins required. there has been significant improvements, features and libraries added in between 0.6 and 0.7: please see the README in the distribution for details. for fits and giggles, to show what's possible in only 400 lines of python, here is a game of asteroids, written by joe rumsey. yes, it runs under pyjamas-desktop too. http://pyjs.org/examples/asteroids/public/Space.html For more information, see: http://pyjs.org http://pyjs.org/FAQ.html http://pyjs.org/features.html http://groups.google.com/group/pyjamas-dev downloads: http://pypi.python.org/pypi/Pyjamas http://code.google.com/p/pyjamas http://sf.net/projects/pyjamas known major bugs: http://code.google.com/p/pyjamas/issues #391 (google chrome beta) #384 (text selection on opera 10.51) contributions and investigations by community members to fix these and other issues welcomed and encouraged.

[ANN]: 'tren' Cross-Platform Batch Renaming Tool, Version 1.217 Released And Available
by Tim Daneliuk April 23, 2010

April 23, 2010

'tren' Version 1.217 is now released and available for download at: http://www.tundraware.com/Software/tren --------------------------------------------------------------------- What's New In This Release? --------------------------- This is the initial public release. What Is 'tren'? ------------------ 'tren' is a general purpose file and directory renaming tool. Unlike commands like 'mv', 'tren' is particularly well suited for renaming *batches* of files and/or directories with a single command line invocation. 'tren' eliminates the tedium of having to script simpler tools to provide higher-level renaming capabilities. 'tren' is also adept at renaming only *part of an existing file or directory name* either based on a literal string or a regular expression pattern. You can replace any single, group, or all instances of a given string in a file or directory name. 'tren' implements the idea of a *renaming token*. These are special names you can embed in your renaming requests that represent things like the file's original name, its length, date of creation, and so on. There are even renaming tokens that will substitute the content of any environment variable or the results of running a program from a shell back into the new file name. 'tren' can automatically generate *sequences* of file names based on their dates, lengths, times within a given date, and so on. In fact, sequences can be generated on the basis of any of the file's 'stat' information. Sequence "numbers" can be ascending or descending and the count can start at any initial value. Counting can take place in one of several internally defined counting "alphabets" (decimal, hex, octal, alpha, etc.) OR you can define your own counting alphabet. This allows you to create sequences in any base (2 or higher please :) using any symbol set for the count. 'tren' is written in pure Python and requires Python version 2.6.x or later. It is known to run on various Unix-like variants (FreeBSD, Linux, MacOS X) as well as Windows. It will also take advantage of 'win32all' Python extensions on a Windows system, if they are present. --------------------------------------------------------------------- Complete details of all fixes, changes, and new features can be found in the WHATSNEW.txt and documentation files included in the distribution. A FreeBSD port has been submitted as well.

colorama : Simple cross-platform colored terminal text.
by Tartley April 19, 2010

April 19, 2010

ANSI escape character sequences are commonly used to produce colored terminal text on Macs and Unix. Colorama makes these work on Windows too. It works by wrapping stdout and stderr on Windows, with proxies that filter ANSI escape sequences out of printed text, and converting them into equivalent win32 calls. This has the happy side-effect that existing applications or libraries which already use ANSI sequences to produce colored output on Linux or Macs (eg. using packages like 'termcolor') will also work on Windows, simply by calling Colorama.init(). I realise an alternative way to achieve the same result is to install the ANSI.SYS device driver, but it is fiddly and intrusive for the Python developer to do this on their machine of their application's end-user. This is the first release, and while it seems to work for me, no doubt there are still many problems with it. Ruthless feedback is very welcome, about both implementation and philosophy. http://pypi.python.org/pypi/colorama

Announcing virtualenvwrapper 2.1
by Doug Hellmann April 18, 2010

April 18, 2010

What is virtualenvwrapper ========================= virtualenvwrapper_ is a set of extensions to Ian Bicking's virtualenv_ tool. The extensions include wrappers for creating and deleting virtual environments and otherwise managing your development workflow, making it easier to work on more than one project at a time without introducing conflicts in their dependencies. What's New in 2.1 ================= The primary purpose of this release is a set of enhancements to support virtualenvwrapper.project_, a new extension to manage project work directories with templates. 2.1 also includes several smaller changes and bug fixes. - Add support for ksh. Thanks to Doug Latornell for doing the research on what needed to be changed. - Test import of virtualenvwrapper.hook_loader on startup and report the error in a way that should help the user figure out how to fix it (issue #33). - Update mkvirtualenv documentation to include the fact that a new environment is activated immediately after it is created (issue #30). - Added hooks around cpvirtualenv. - Made deactivation more robust, especially under ksh. - Use Python's ``tempfile`` module for creating temporary filenames safely and portably. - Fix a problem with ``virtualenvwrapper_show_workon_options`` that caused it to show ``*`` as the name of a virtualenv when no environments had yet been created. - Change the hook loader so it can be told to run only a set of named hooks. - Add support for listing the available hooks, to be used in help output of commands like virtualenvwrapper.project's mkproject. - Fix mkvirtualenv -h option behavior. - Change logging so the $WORKON_HOME/hook.log file rotates after 10KiB. .. _virtualenv: http://pypi.python.org/pypi/virtualenv .. _virtualenvwrapper: http://www.doughellmann.com/projects/virtualenvwrapper/ .. _virtualenvwrapper.project: http://www.doughellmann.com/projects/virtualenvwrapper.project/

IPythonQt and IPythonZMQ projects
by Gerardo Gutierrez April 16, 2010

April 16, 2010

Hi all. I'm writting to tell you about some projects we're developing for you and the entire python programmers community. Read some of the documentation of the proposals and please tell us what are your ideas and what do you want or expect to see of this. I'm going to leave you a summary and some links: *IPythonQt* We will implement a Qt-based Graphical User Interface (GUI) to execute Python code with an interpreter that runs in a separate process and the two systems (GUI frontend and interpreter kernel) communicating via the ZeroMQ Messaging library. The bulk of the implementation will be done without dependencies on IPython (only on Zmq). Once the key features are ready, IPython-specific features can be added using the IPython codebase. *links*: http://ipythonqt.blogspot.com/ https://code.launchpad.net/~ipython-contrib/ipython/qt-frontend *IPythonZMQ* IPython's execution in a command-line environment will be ported to a two process model using the ZeroMQ library for inter-process communication. This will: - prevent an interpreter crash from destroying the user session, - allow multiple clients to interact simultaneously with a single interpreter - allow IPython to reuse code for local execution and distributed computing (DC) - give us a path for Python3 support, since ZeroMQ supports Python3 while Twisted (what we use today for DC) does not. *links*: http://ipythonzmq.blogspot.com/ https://code.launchpad.net/~ipython-contrib/+junk/ipython-zmq Best regards. -- Gerardo Gutiérrez Gutiérrez <http://he1.udea.edu.co/gweb> Physics student Universidad de Antioquia Computational physics and astrophysics group (FACom<http://urania.udea.edu.co/sites/sites.php> ) Computational science and development branch(FACom-dev<http://urania.udea.edu.co/sites/facom-dev/> ) Usuario Linux #492295

by Krister Hedfors April 15, 2010

April 15, 2010

sqldict - dict with sqlalchemy database-agnostic back-end You can now create a dict out of arbitrary key/value columns of any existing database table, in addition to ordinary dedicated strict or auto-pickling sqldicts. Basic use: $ easy_install sqldict $ easy_install sqlalchemy >>> from sqldict import sqldict >>> from sqlalchemy import * >>> #d0 = sqldict("mysql://user:pass@dbhost/dbname", "table0", create=1) >>> engine = create_engine("sqlite://") >>> d1 = sqldict(engine, "table1", create=1) >>> d2 = sqldict(engine, "table2", create=1, valtype=Integer) >>> contents = {"asd":123} >>> d1.update(contents) >>> d2.update(contents) >>> assert d1["asd"] == "123" >>> assert d2["asd"] == 123 Make dict from existing database table: >>> _ = engine.execute("create table asd (i integer, s varchar(50))") >>> _ = engine.execute("insert into asd values (42, 'gubbe')") >>> d3 = sqldict(engine, "asd", keycol="s", valcol="i") >>> d4 = sqldict(engine, "asd", keycol="i", valcol="s") >>> assert d3["gubbe"] == 42 >>> assert d4[42] == "gubbe" Key-val serializing and only val serializing sqldicts; a's key column type is String, b's key column type is Integer. The obvious use case for b is HUGE dicts where only integer indexes are allowed: >>> a = sqldict(engine, "serty1", create=1, serialize=1) >>> b = sqldict(engine, "serty2", create=1, serialize=1, keytype=Integer) >>> >>> a[1] = (2,3) >>> assert a[1] == (2,3) >>> b[4] = (5,6) >>> assert b[4] == (5,6) Have fun! /Krister Hedfors

Announcing IronPython 2.6.1
by David DiCato April 12, 2010

April 12, 2010

Hello Python Community, We're pleased to announce the final release of IronPython 2.6.1. This version of IronPython makes great strides in stability and compatibility, including a considerable number of targeted bugfixes. This is our largest servicing release to date, and with your help both before and during the RC phase, along with the simultaneous release of .NET 4.0, this has become a very exciting release for all of us. IronPython 2.6.1 comes in two flavors - one that runs on top of .NET 4.0, and one that runs on any earlier framework starting with .NET 2.0 SP1. They can both be downloaded at http://ironpython.codeplex.com/releases/view/36280. We'd like to place a particular emphasis on the .NET 4.0 flavor of IronPython 2.6.1 and encourage all of you to try it out. It has a number of advantages over the 2.0 version, some of which Dave discusses on his blog at http://knowbody.livejournal.com/20751.html. These include faster startup time, compatibility with C#'s new dynamic keyword, and access to the numerous new features present in the updated Framework. The final release of Microsoft .NET Framework 4.0 is publically available as of today, and is required for this flavor of IronPython 2.6.1. Download it here: http://www.microsoft.com/downloads/details.aspx?FamilyID=9cfb2d51-5ff4-4491… The IronPython 2.6.1 RC included fixes for well over 50 bugs, large and small. Ctypes has had a number of significant updates, including union support, variant_bool, and wintypes. Another focus has been on sys.settrace, making debugging more reliable. For example, sys.settrace now returns the correct frame, supports tracing through modules, and no longer interferes with "import os". Other notable fixes include thread-safe importing, and the missing error code in _winreg exception. In addition, we've made a substantial improvement in import time. Not only does this reduce startup time, but it can speed up the importing of large, definition-heavy modules by up to 50%. As you might imagine, the .NET 4.0 flavor of IronPython 2.6.1 RC has a few of its own changes designed for better interoperability with the framework. These include fixing some errors with Func<> and better runtime isolation when similarly-named assemblies in different locations are loaded in multiple engines. In addition, both the .NET 2.0 and .NET 4.0 builds support the new .NET 4.0 IStructuralEquatable and IStructuralComparable interfaces and maps them to the appropriate operations (__eq__, __hash__, __gt__, etc.). In the case of .NET 4.0, this replaces IValueEquality as the gold standard for defining equality in an interop-friendly manner. In the .NET 2.0 build, these interfaces are copied so that their use can be phased in while retaining IValueEquality for backwards compatibility. Since the RC, we have fixed numerous other issues, as well as adding CPython's ssl.py to our distribution. We've also made some major unicode-related changes in response to your feedback on the mailing list, changes that improve compatibility with certain third-party applications including Django. In particular, invoking unicode() or using unicode string formatting will now call __unicode__() first if it is present on the object. Finally, we've included a new code sample that shows how to use __clrtype__ to create custom CLR classes from IronPython. This sample is a sneak preview of what we expect will become a fully supported IronPython module, so we encourage anyone who is so inclined to try it out and let us know how it goes. Special thanks to Albert Szilvasy, amajorek, cendalc, clovery, egonw_, Eloff, essey, fabiofz, gjones, gpgemini, Haibo Luo, igalse, jazzcat, jdhardy, jlunder, JustinCle, klrohe, László de Almásy, laughingboy, lbaker, Lukas Cenovsky, marten_range, olav, paulfelix, pl6306, razam, roinet, russomf, sanxiyn, see_toronto <at> web <dot> de, Thomas Heller, variant77, vernondcole, William Reade, and Wolfram for reporting issues and making this a great release. Happy scripting! - The IronPython Team

OpenHatch: Find ways to contribute to open source (including Python itself)
by Asheesh Laroia April 12, 2010

April 12, 2010

Hi all! I'm happy to announce the new version of the OpenHatch volunteer opportunity finder. Volunteer opportunity finder ---------------------------- Looking for a way to get involved in open source, but don't know where to start? Try browsing bugs in the OpenHatch volunteer opportunity finder: https//openhatch.org/search/ At PyCon, I led an open space where some of us tried finding things to work on. We found "easy" documentation bugs in Python, and wrote up patches. Within a few weeks, our patches were comitted to the Python core. Contributors to hundreds of projects (including Python itself) label bugs as good for new contributors. Those bugs are an opportunity for you to find a new project to contribute to in open source, so try browsing them at https://openhatch.org/search/?q=&toughness=bitesize Do you run an open source project? You can add your project to our index by clicking "Add a bug tracker." If you want to get new contributors more easily, try tagging bugs in your bug tracker as "bitesize."We're always looking for more projects to include in our crawls. About OpenHatch --------------- We're a website for helping people find ways to get involved in free, open source software. We also run a profile engine where you can tell your story in open source, emphasizing all the ways you've been involved in projects. (Successful open source projects take more than just code!) For more info ------------- Keep in touch by: * Joining #openhatch on irc.freenode.net * Replying to me and getting on our announcements list * Subscribing to @openhatchery on Twitter/Identi.ca * Reading our blog at https://openhatch.org/blog/ Or grab our source code: https://openhatch.org/source-code-etc/ -- Asheesh. -- ... bacteriological warfare ... hard to believe we were once foolish enough to play around with that. -- McCoy, "The Omega Glory", stardate unknown

ANN: unittest2 0.4.0 released
by Michael Foord April 8, 2010

April 8, 2010

Hello all, I'm pleased to announce the release of version 0.4.0 of unittest2. * unittest2 on PyPI: http://pypi.python.org/pypi/unittest2 * Article introducing unittest2: http://www.voidspace.org.uk/python/articles/unittest2.shtml * Development docs for unittest (new features documented) <http://docs.python.org/dev/library/unittest.html * Mercurial Development Repository: http://hg.python.org/unittest2 unittest2 is an enhanced version of unittest including a standard test runner (automatic test discovery), class and module level fixtures (``setUpClass`` / ``setUpModule`` etc), many powerful new assert methods, better resource management with ``addCleanups`` and a host of other new features. These new features are *all* going into the Python version of unittest in Python 2.7 and Python 3.2. The point of unittest2 is that it works with Python 2.4 - 2.6; you can use it now. The latest release is 0.4.0, which roughly equates to the feature set that will be in unittest in Python 2.7 beta 1 which is due out any minute now. The last public release of unittest2 I announced was version 0.2.0 and there have been several new and important features since then. For a good roundup of the new features, see my blog entry: * http://www.voidspace.org.uk/python/weblog/arch_d7_2010_04_03.shtml#e1171 The full changelog for versions 0.3.0 and 0.4.0: 2010/04/08 - 0.4.0 ------------------ Addition of ``removeHandler`` for removing the control-C handler. ``delta`` keyword argument for ``assertAlmostEqual`` and ``assertNotAlmostEqual``. Addition of -b command line option (and ``TestResult.buffer``) for buffering stdout / stderr during test runs. Addition of ``TestCase.assertNotRegexpMatches``. Allow test discovery using dotted module names instead of a path. All imports requiring the signal module are now optional, for compatiblity with IronPython (or other platforms without this module). Tests fixed to be compatible with nosetest. 2010/03/26 - 0.3.0 ------------------ ``assertSameElements`` removed and ``assertItemsEqual`` added; assert that sequences contain the same elements. Addition of -f/--failfast command line option, stopping test run on first failure or error. Addition of -c/--catch command line option for better control-C handling during test runs. Added ``BaseTestSuite``, for use by frameworks that don't want to support shared class and module fixtures. Skipped test methods no longer have ``setUp`` and ``tearDown`` called around them. Faulty ``load_tests`` functions no longer halt test discovery. Using non-strings for failure messages now works. Potential for ``UnicodeDecodeError`` whilst creating failure messages fixed. Split out monolithic test module into a package. BUGFIX: Correct usage message now shown for unit2 scripts. BUGFIX: ``__unittest`` in module globals trims frames from that module in reported stacktraces. All the best, Michael Foord -- http://www.ironpythoninaction.com/ http://www.voidspace.org.uk/blog

ANN: oejskit 0.8.8 JavaScript in-browser testing with py.test plugin and unittest.py glue
by Samuele Pedroni April 7, 2010

April 7, 2010

I'm happy to announce a new release of OE jskit 0.8.8 available on PyPI. Main points of interest: * the code to check for the presence of browsers locally has been improved, browser specifications can now with much more confidence list absent browsers and the respective runs/tests will be skipped * added a workaround to a bug in Firefox 3.5 that interferes with the global variable leak detection code, this is simply turned off for FF3.5. The bug itself is fixed in FF3.6 About OE jskit: jskit contains infrastructure and in particular a py.test plugin to enable running unit tests for JavaScript code inside browsers. It contains also glue code to run JavaScript tests from unittest.py based test suites. The approach also enables to write integration tests such that the JavaScript code is tested against server-side Python code mocked as necessary. Any server-side framework that can already be exposed through WSGI can play. The plugin requires py.test 1.1.1 and should also work with current trunk. More information and downloading at: http://pypi.python.org/pypi/oejskit including a changelog, documentation and the talk I gave at Europython 2009. jskit was initially developed by Open End AB and is released under the MIT license. In various incarnations it has been in use and useful at Open End for more than two years, we are quite happy to share it.

WxPython's Py Suite (PyCrust, etc.) updated with new "magic" features and new notebook interface shell, PySlices
by David Mashburn April 6, 2010

April 6, 2010

WxPython's Py Suite (PyCrust, etc.) updated with new "magic" features and new notebook interface shell, PySlices. WxPython has, for a long time, included PyCrust, one of the most popular Python shells. PyCrust has found uses in a number of projects, including Stani's Python Editor and some projects at Enthought. PyCrust, part of the larger "Py suite" of tools, had been dormant for some time now, but it is now under a new maintainer and has recently been updated! Py Suite 0.9.8.3 can be found in the wxPython 2.9 svn branch (import path is wx.py), on a Google code page (http://code.google.com/p/wxpysuite/) and in PyPI (package name is wx_py). Py Suite 0.9.8.3 requires wxPython 2.8 or later. A summary of the major changes follows: The biggest change is certainly the inclusion of a new notebook interface version of PyCrust called "PySlices" into the Py suite! It features multi-line execution in re-runnable code blocks called "slices" and the ability to save to a simple .pyslices format that when converted to .py is still valid python code! PySlices is a great lightweight alternative to the excellent SAGE and Reinteract projects. Both PyCrust and PySlices now include some ipython style "magic" features: Unix-style path functions: "cd", "ls", and "pwd" all work as expected Space based function calls: "f 1" will automatically convert to "f(1)" "?" character to call help: "?dir" is equivalent to "help(dir)" "!" character to call operating system shell commands: "!foobar" is automatically converted to "commands.getoutput('foobar')" There is also a highly experimental shell (not included in the wxPython svn version) called SymPySlices that uses sympy for for automatic symbol creation, and allows for the use of unicode charcters directly in python. Mathematical operators (including some infix operators via ast parsing) are supported. SymPySlices additionally requires Python 2.6 or later and sympy. This is still very experimental, so please let me know if you have questions, problems, or ideas (david.n.mashburn(a)gmail.com)! You can read more about these projects on the google code page: http://code.google.com/p/wxpysuite/ at the PyPI page: http://pypi.python.org/pypi/wx_py/0.9.8.3 and in the original wxTrac ticket: http://trac.wxwidgets.org/ticket/10959 Feel free to email me with questions, bugs, and feature requests! <P><A HREF="http://code.google.com/p/wxpysuite/">Py Suite 0.9.8.3</A> - WxPython's Py Suite (PyCrust, etc.) updated with new "magic" features and new notebook interface shell, PySlices.

virtualenvwrapper 2.0
by Doug Hellmann April 6, 2010

April 6, 2010

What is virtualenvwrapper ========================= virtualenvwrapper_ is a set of extensions to Ian Bicking's virtualenv_ tool. The extensions include wrappers for creating and deleting virtual environments and otherwise managing your development workflow, making it easier to work on more than one project at a time without introducing conflicts in their dependencies. What's New in 2.0 ================= This new version uses a significantly rewritten version of the hook/callback subsystem to make it easier to share extensions. For example, released at the same time is virtualenvwrapper-emacs-desktop_, a plugin to switch emacs project files when you switch virtualenvs. Existing user scripts should continue to work as-written. Any failures are probably a bug, so please report them on the bitbucket tracker. Documentation for the new plugin system is available in the virtualenvwrapper docs_. I also took this opportunity to change the name of the shell script containing most of the virtualenvwrapper functionality from virtualenvwrapper_bashrc to virtualenvwrapper.sh. This reflects the fact that several shells other than bash are supported (bash, sh, ksh, and zsh are all reported to work). You'll want to update your shell startup file after upgrading to 2.0. The work to create the plugin system was triggered by a couple of recent feature requests for environment templates and for a new command to create a sub-shell instead of simply changing the settings of the current shell. The new, more powerful, plugin capabilities will make it easier to develop these and similar features. I'm looking forward to seeing what the community comes up with. I especially want someone to write a plugin to start a copy of a development server for a Django project if one is found in a virtualenv. You'll get bonus points if it opens the home page of the server in a web browser. .. _virtualenv: http://pypi.python.org/pypi/virtualenv .. _virtualenvwrapper: http://www.doughellmann.com/projects/virtualenvwrapper/ .. _virtualenvwrapper-emacs-desktop: http://www.doughellmann.com/projects/virtualenvwrapper-emacs-desktop/ .. _docs: http://www.doughellmann.com/docs/virtualenvwrapper/

Grease 0.2 Released
by Casey Duncan April 5, 2010

April 5, 2010

Grease is a pluggable and highly extensible 2D game engine and framework for Python. The intent of this project is to provide a fresh approach to Python game development. The component-based architecture allows games to be constructed bit by bit with built-in separation of concerns. The engine acknowledges that all game projects are unique and have different requirements. Thus Grease does not attempt to provide one-size-fits-all solutions. Instead it provides pluggable components and systems than can be configured, adapted and extended to fits the particular needs at hand. This early release has only basic functionality, but it already demonstrates the power of the underlying architecture for rapid development. The goals of the project include: * Making Python game development faster and more fun by allowing the developer to focus on creating their game rather than getting bogged down in architecture, low-level apis and adapting ill-fitting tools together. * To provide pluggable and extensible parts that implement first-class techniques and algorithms that can be leveraged for many projects. * To fully document the engine and provide examples that demonstrate best practices for others to base their projects on. * To facilitate outside contribution of parts and ideas into the framework that have proven useful in the wild. * To provide optional native-code optimized parts for maximum performance, but also provide equivalent parts coded in pure Python for ease of installation and distribution. Not all of these goals have been realized yet, but I feel the project is well on their path. License ------- Grease is distributed under a permissive MIT-style open source license. This license permits you to use grease for commercial or non-commercial purposes free of charge. It makes no demands on how, or whether, you license, or release the code derived from or built upon Grease, other than preservation of copyright notice. For a complete text of the license see the ``LICENSE.txt`` file in the source distrbution. Requirements ------------ Grease is platform-independent and should run on any operating system supporting Python and Pyglet. The following are required to build and install Grease: * Python 2.6 (http://www.python.org/) * Pyglet 1.1 (http://www.pyglet.org/) Downloading Grease ------------------ You can download Grease from the Python package index (pypi): * http://pypi.python.org/pypi/grease/ Documentation ------------- You can browse the documentation online at: * http://pygamesf.org/~casey/grease/doc/ The documentation is also available for offline viewing in the ``doc/build/html`` subdirectory for the source distribution. Development Status ------------------ Grease is alpha software under active development. The APIs may change in future releases, however efforts will be made to minimize breakage between releases.

[ANN] Greenlet 0.3.1 released
by Kyle Ambroff April 5, 2010

April 5, 2010

Announcing the release of greenlet 0.3.1: http://pypi.python.org/pypi/greenlet/0.3.1 0.3.1 is a bugfix release that fixes a critical reference leak bug. The 0.3 release introduced support for passing keyword arguments to the switch method. There was an edge case where an empty keyword argument dictionary would not have its reference count decremented, which would cause a memory leak. Thanks to Marcin Bachry for reporting the bug and providing a patch. What is Greenlet? ----------------- The greenlet package is a spin-off of Stackless, a version of CPython that supports micro-threads called "tasklets". Tasklets run pseudo-concurrently (typically in a single or a few OS-level threads) and are synchronized with data exchanges on "channels". A "greenlet", on the other hand, is a still more primitive notion of micro-thread with no implicit scheduling; coroutines, in other words. greenlet is used by several non-blocking IO packages as a more flexible alternative to Python's built in coroutines. * concurrence * eventlet * gevent Links ----- Mercurial repository: http://bitbucket.org/ambroff/greenlet Documentation: http://packages.python.org/greenlet/ -Kyle Ambroff
