[ANN] Python Tools for Visual Studio 1.1
by Dino Viehland Feb. 10, 2012

Feb. 10, 2012

We're pleased to announce the release of Python Tools for Visual Studio 1.1 http://pytools.codeplex.com/releases/view/76091. Python Tools for Visual Studio (PTVS) is an open-source plug-in for Visual Studio which supports programming with the Python programming language. PTVS supports a broad range of features including: * Supports CPython and IronPython * Python editor with advanced member and signature intellisense * Code navigation: "Find all refs", goto definition, and object browser * Local and remote debugging * Profiling with multiple views * Integrated REPL window with inline matplotlib graphics * Support for HPC clusters and MPI, including debugging & Profiling * Interactive parallel computing via integrated IPython REPL This release includes new core IDE features, a couple of new sample libraries for interacting with Kinect and Excel, and many bug fixes for issues reported since the release of 1.0. The 1.1 release altogether contains over 150 bug fixes and new features since 1.0. For the core IDE features we've added many new features which improve the basic editing experience. This includes a smart tag feature for automatically adding imports, a command for cleaning up unused imports, support for recognizing isinstance() calls and using them for providing improved completions. We've also updated goto definition to go to members defined in the standard library. We've also made several improvements to the project system. Some improvements which should help just about everyone include support for linked files that live outside of the project directory. This makes it easy to keep your project file separate from your code files. For IronPython users you can now add references to .NET projects or .NET assemblies and we'll automatically reload and re-analyze the references when they're rebuilt. For CPython users you can now add a reference to a .pyd extension module enabling analysis of the extension to provide completions. We've also improved intellisense across multiple Python projects in the same solution. This release also includes some improvements to the interactive REPL window. This includes improvements to IPython REPL support including support for inline graphs and proper support for IPython's numbered prompts. We've added support for using IPython mode w/o PyLab - this enables out-of-line graphs and improves the startup time of the interactive window. The debugger has also seen several small improvements in this release. There's a new option to step into the Python standard library while debugging, another option to not break on SystemExit exception with exit codes of zero. Finally we've added support for displaying Python thread name in the threads window. We've also improved the Debug->Attach support and made it easier to attach to a process which is not actively running Python code. Another major addition to 1.1 includes the addition of two additional sample libraries available as separate downloads: PyKinect for working with the Kinect Beta SDK and Pyvot for working with Excel spreadsheets. Once downloaded and installed these plug-in to Visual Studio and provide templates; and they provide built-in support for installing into one of the recognized Python interpreters via Tools->Python Tools->Samples. We'd like to thank all of the users who took the time to report issues and feedback for this release: 445363200, adv12, Andrew, AphexSA, benpmorgan, chadbr, dgkbny, drgn, holmboe, hyh, jimpeak, juanalumni, kingnaoufal, lblanchon, liuzhenhai, mahpour, MichaelBaker, po6856, pztrick44, RobertMcGinley, salerio, slide_o_mix, somini, SoonStudios, stakemura, stephenkennedy, sumitbasu, swift_dev, synergetic, teebot, tiphon, timeisaparallax, tonyandrewmeyer, xavier_grundus, and Zooba.

ANN: Sarge, a library wrapping the subprocess module, has been released.
by Vinay Sajip Feb. 10, 2012

Feb. 10, 2012

Sarge, a cross-platform library which wraps the subprocess module in the standard library, has been released. What does it do? ---------------- Sarge tries to make interfacing with external programs from your Python applications easier than just using subprocess alone. Sarge offers the following features: * A simple way to run command lines which allows a rich subset of Bash- style shell command syntax, but parsed and run by sarge so that you can run on Windows without cygwin (subject to having those commands available): >>> from sarge import capture_stdout >>> p = capture_stdout('echo foo | cat; echo bar') >>> for line in p.stdout: print(repr(line)) ... 'foo\n' 'bar\n' * The ability to format shell commands with placeholders, such that variables are quoted to prevent shell injection attacks. * The ability to capture output streams without requiring you to program your own threads. You just use a Capture object and then you can read from it as and when you want. Advantages over subprocess --------------------------- Sarge offers the following benefits compared to using subprocess: * The API is very simple. * It's easier to use command pipelines - using subprocess out of the box often leads to deadlocks because pipe buffers get filled up. * It would be nice to use Bash-style pipe syntax on Windows, but Windows shells don't support some of the syntax which is useful, like &&, ||, |& and so on. Sarge gives you that functionality on Windows, without cygwin. * Sometimes, subprocess.Popen.communicate() is not flexible enough for one's needs - for example, when one needs to process output a line at a time without buffering the entire output in memory. * It's desirable to avoid shell injection problems by having the ability to quote command arguments safely. * subprocess allows you to let stderr be the same as stdout, but not the other way around - and sometimes, you need to do that. Python version and platform compatibility ----------------------------------------- Sarge is intended to be used on any Python version >= 2.6 and is tested on Python versions 2.6, 2.7, 3.1, 3.2 and 3.3 on Linux, Windows, and Mac OS X (not all versions are tested on all platforms, but sarge is expected to work correctly on all these versions on all these platforms). Finding out more ---------------- You can read the documentation at http://sarge.readthedocs.org/ There's a lot more information, with examples, than I can put into this post. You can install Sarge using "pip install sarge" to try it out. The project is hosted on BitBucket at https://bitbucket.org/vinay.sajip/sarge/ And you can leave feedback on the issue tracker there. I hope you find Sarge useful! Regards, Vinay Sajip

PyPy 1.8 released
by Maciej Fijalkowski Feb. 10, 2012

Feb. 10, 2012

============================ PyPy 1.8 - business as usual ============================ We're pleased to announce the 1.8 release of PyPy. As habitual this release brings a lot of bugfixes, together with performance and memory improvements over the 1.7 release. The main highlight of the release is the introduction of `list strategies`_ which makes homogenous lists more efficient both in terms of performance and memory. This release also upgrades us from Python 2.7.1 compatibility to 2.7.2. Otherwise it's "business as usual" in the sense that performance improved roughly 10% on average since the previous release. you can download the PyPy 1.8 release here: http://pypy.org/download.html .. _`list strategies`: http://morepypy.blogspot.com/2011/10/more-compact-lists-with-list-strategie… What is PyPy? ============= PyPy is a very compliant Python interpreter, almost a drop-in replacement for CPython 2.7. It's fast (`pypy 1.8 and cpython 2.7.1`_ performance comparison) due to its integrated tracing JIT compiler. This release supports x86 machines running Linux 32/64, Mac OS X 32/64 or Windows 32. Windows 64 work has been stalled, we would welcome a volunteer to handle that. .. _`pypy 1.8 and cpython 2.7.1`: http://speed.pypy.org Highlights ========== * List strategies. Now lists that contain only ints or only floats should be as efficient as storing them in a binary-packed array. It also improves the JIT performance in places that use such lists. There are also special strategies for unicode and string lists. * As usual, numerous performance improvements. There are many examples of python constructs that now should be faster; too many to list them. * Bugfixes and compatibility fixes with CPython. * Windows fixes. * NumPy effort progress; for the exact list of things that have been done, consult the `numpy status page`_. A tentative list of things that has been done: * multi dimensional arrays * various sizes of dtypes * a lot of ufuncs * a lot of other minor changes Right now the `numpy` module is available under both `numpy` and `numpypy` names. However, because it's incomplete, you have to `import numpypy` first before doing any imports from `numpy`. * New JIT hooks that allow you to hook into the JIT process from your python program. There is a `brief overview`_ of what they offer. * Standard library upgrade from 2.7.1 to 2.7.2. Ongoing work ============ As usual, there is quite a bit of ongoing work that either didn't make it to the release or is not ready yet. Highlights include: * Non-x86 backends for the JIT: ARMv7 (almost ready) and PPC64 (in progress) * Specialized type instances - allocate instances as efficient as C structs, including type specialization * More numpy work * Since the last release there was a significant breakthrough in PyPy's fundraising. We now have enough funds to work on first stages of `numpypy`_ and `py3k`_. We would like to thank again to everyone who donated. * It's also probably worth noting, we're considering donations for the Software Transactional Memory project. You can read more about `our plans`_ Cheers, The PyPy Team .. _`brief overview`: http://doc.pypy.org/en/latest/jit-hooks.html .. _`numpy status page`: http://buildbot.pypy.org/numpy-status/latest.html .. _`numpy status update blog report`: http://morepypy.blogspot.com/2012/01/numpypy-status-update.html .. _`numpypy`: http://pypy.org/numpydonate.html .. _`py3k`: http://pypy.org/py3donate.html .. _`our plans`: http://morepypy.blogspot.com/2012/01/transactional-memory-ii.html

notmm 0.4.4 released
by Etienne Robillard Feb. 9, 2012

Feb. 9, 2012

Hi, I'm very happy to announce the release of the notmm toolkit version 0.4.4 "Never Give Up Never Surrender" available via the Python Cheeseshop! :) New features and major changes includes: . Bundled BlogEngine, LibAuthKit, LibSchevo as third-party apps in extras . Improved Cython support up to 0.15 . Improved stability of core packages, examples, and third-party apps (BlogEngine, LibAuthkit, LibSchevo) . Experimental WebDAV controller using PyWebDAV library . Many Bug Fixes.. :) Download location: http://pypi.python.org/pypi/notmm/0.4.4 A few notes on gthc.org status: Gthc.org and gthcfoundation.org are still down until further notices for technical reasons. Furthermore I'm also looking for cheap alternatives to host a notmm.org domain, so if interested, please let me know. Finally, this project could have never been done without a free-access internet and as SOPA may currently be under status quo in the US, plans for bill C-11 are under way in Canada, threatening once again freedom of expression over this neutral media and environment for content creators, artists, and typical users to develop and share alike without mediocre restrictions, artistic creations which requires most importantly strong net neutrality over ill-defined user-moderation! Best regards, Etienne -- Etienne Robillard Lead Developer and Consultant Green Tea Hackers Club Email: animelovin(a)gmail.com Website: http://gthcfoundation.org
