pyC11 initial publication
by Volker Birk 04 May '13

04 May '13

pyC11 is a grammar to parse programs in the C programming language following ISO/IEC 9899:2011. It is written using pyPEG, a parsing framework for Python. The grammar supports Python 2.7 and 3.x. The test bench requires py.test. This is the initial upload. The grammar is incomplete. Parsing C expressions works, but parsing complete C programs does not work yet. pyC11 is meant to be used for parsing, modifying and generating C expressions and programs. It is a real world sample how to use pyPEG. pyC11 is provided under the GNU GPL 2.0. You can find pyC11 on Bitbucket at <https://bitbucket.org/fdik/pyc11>.

pyPEG 2.11 released
by Volker Birk 04 May '13

04 May '13

Feature enhancements are provided, like a method for memory cache clearing and improving composing and text representation. Some small bugs are fixed. pyPEG is a quick and easy solution for creating a parser in Python programs. pyPEG uses a PEG language in Python data structures to parse, so it can be used dynamically to parse nearly every context free language. The output is a plain Python data structure called pyAST, or, as an alternative, XML. pyPEG implements an intrinsic Packrat parser. Memoization is used for performance improvements. pyPEG is used by defining a data model with a grammar. Therefore it cannot only be used to parse text, but to compose text out of the language model, too. It can be used for code generation. You can find pyPEG2 in the PyPI repository. The homepage is here: <http://fdik.org/pyPEG>. pyPEG is maintained in a Bitbucket repository at <https://bitbucket.org/fdik/pypeg/>.

devpi-server-0.8: fast'n easy-to-deploy pypi.python.org proxy =============================================================== devpi-server is an easy-to-deploy caching proxy server for pypi.python.org, providing fast and reliable installs when used by pip or easy_install. devpi-server-0.8 brings three improvements: - fixed issue4: bug fixed in pypi.python.org to better survive network outage. - a new way to bootstrap a self-contained pre-configured "virtualenv" directory, guiding you to set it up on your laptop: devpi-server --gendeploy=TARGETDIR --port=3200 --redisport=3201 will create all that is neccessary for controled deployment on your laptop. - the project page / README has been reworked a bit: http://pypi.python.org/pypi/devpi-server If you have questions or issues, you may also drop by the brand new IRC channel #devpi on freenode. have a nice weekend, holger

ANN: New WinPython with Python 2.7.4 and 3.3.1 (32/64bit)
by Pierre Raybaut 03 May '13

03 May '13

Hi all, I am pleased to announce that four new versions of WinPython have been released yesterday with Python 2.7.4 and 3.3.1, 32 and 64 bits. Many packages have been added or upgraded (see the automatically-generated changelogs). Special thanks to Christoph Gohlke for building most of the binary packages bundled in WinPython. WinPython is a free open-source portable distribution of Python for Windows, designed for scientists. It is a full-featured (see http://code.google.com/p/winpython/wiki/PackageIndex) Python-based scientific environment: * Designed for scientists (thanks to the integrated libraries NumPy, SciPy, Matplotlib, guiqwt, etc.: * Regular *scientific users*: interactive data processing and visualization using Python with Spyder * *Advanced scientific users and software developers*: Python applications development with Spyder, version control with Mercurial and other development tools (like gettext) * *Portable*: preconfigured, it should run out of the box on any machine under Windows (without any installation requirements) and the folder containing WinPython can be moved to any location (local, network or removable drive) * *Flexible*: one can install (or should I write "use" as it's portable) as many WinPython versions as necessary (like isolated and self-consistent environments), even if those versions are running different versions of Python (2.7, 3.3) or different architectures (32bit or 64bit) on the same machine * *Customizable*: using the integrated package manager (wppm, as WinPython Package Manager), it's possible to install, uninstall or upgrade Python packages (see http://code.google.com/p/winpython/wiki/WPPM for more details on supported package formats). *WinPython is not an attempt to replace Python(x,y)*, this is just something different (see http://code.google.com/p/winpython/wiki/Roadmap): more flexible, easier to maintain, movable and less invasive for the OS, but certainly less user-friendly, with less packages/contents and without any integration to Windows explorer [*]. [*] Actually there is an optional integration into Windows explorer, providing the same features as the official Python installer regarding file associations and context menu entry (this option may be activated through the WinPython Control Panel), and adding shortcuts to Windows Start menu. Enjoy!
