ANN: Ophelia 0.3 - Create web sites from TAL templates
by Thomas Lotze 06 Jul '07

06 Jul '07

Ophelia 0.3 has just been released. Ophelia creates XHTML pages from templates written in TAL, the Zope Tag Attribute Language. It is designed to reduce code repetition to zero. The package contains both a WSGI application running Ophelia as well as a request handler for mod_python, the Python module for the Apache2 web server. Additionally, a script is included that renders a page and dumps it to stdout, and another one that runs a wsgiref based HTTP server hosting Ophelia's WSGI application. Ophelia is released under the Zope Public License, version 2.1. To use Ophelia 0.3, you need Python 2.4. The mod_python request handler requires mod_python 3.3 or better. The package is available from the Python package index as a source distribution and a Python 2.4 egg: <http://cheeseshop.python.org/pypi/ophelia> The source code contains a zc.buildout configuration for an environment including Apache and mod_python. You can access the source code repository at <https://svn.thomas-lotze.de/repos/public/Ophelia/>, browse it using ViewCVS at <http://svn.thomas-lotze.de/svn-public/Ophelia/>, or visit Ophelia's web page, containing a commented live usage example, at <http://www.thomas-lotze.de/en/software/ophelia/>. >From the documentation: What kind of sites is Ophelia good for? ======================================= Static content -------------- Consider Ophelia as SSI on drugs. It's not fundamentally different, just a lot friendlier and more capable. Use Ophelia for sites where you basically write your HTML yourself, except that you need write the recurring stuff only once. Reducing repetition to zero comes at a price: your site must follow a pattern for Ophelia to combine your templates the right way. Consider your site's layout to be hierarchical: there's a common look to all your pages, sections have certain characteristics, and each page has unique content. It's crucial to Ophelia that this hierarchy reflect in the file system organization of your documents; how templates combine is deduced from their places in the hierarchy of directories. Dynamic content --------------- Ophelia makes the Python language available for including dynamic content. Each template file may include a Python script. Python scripts and templates contributing to a page share a common set of variables to modify and use. Ophelia's content model is very simple and works best if each content object you publish is its own view: the page it is represented on. If you get content from external resources anyway (e.g. a database or a version control repository), it's still OK to use Ophelia even with multiple views per content object as long as an object's views don't depend on the object's type or even the object itself. Trying to use Ophelia on a more complex site will lead to an ugly entanglement of logic and presentation. Don't use Ophelia for sites that are actually web interfaces to applications, content management systems and the like. -- Viele Grüße, Thomas

bbfreeze 0.95.0
by Ralf Schmitt 06 Jul '07

06 Jul '07

Hi all, I've just uploaded bbfreeze 0.95.0 to python's cheeseshop. bbfreeze creates standalone executables from python scripts. It's similar in functionality to py2exe or cx_Freeze. *NEW* support for egg files: bbfreeze scans zipped egg files and now includes whole egg files/directories in the distribution. Programs using setuptools' pkg_resources module will now work. It offers the following features: easy installation bbfreeze can be installed with setuptools' easy_install command. zip/egg file import tracking bbfreeze tracks imports from zip files. multiple script freezing bbfreeze can freeze multiple scripts at once. python interpreter included bbfreeze will create an extra executable named 'py', which might be used like the python executable itself. bbfreeze works on windows and UNIX-like operating systems. It currently does not work on OS X. bbfreeze has been tested with python 2.4 and 2.5. bbfreeze will not work with python versions prior to 2.3 as it uses the zipimport feature introduced with python 2.3. Links -------- cheese shop entry: http://cheeseshop.python.org/pypi/ bbfreeze/<http://cheeseshop.python.org/pypi/bbfreeze/> homepage: http://systemexit.de/bbfreeze/ mercurial repository: http://systemexit.de/repo/bbfreeze Regards, - Ralf

Pypar 2.0alpha update - Simple and efficient MPI binding for Python.
by Ole Nielsen 06 Jul '07

06 Jul '07

pypar 2.0alpha released on sourceforge. Pypar is a simple and efficient MPI binding for Python Copyright (C) 2001-2007 Ole M. Nielsen ------------------------------------------------------- This is to announce an upgrade of pypar, ver 2.0 alpha - a simple and efficient Python binding to MPI for parallel programming using Python. Version 1.0 was announced on this mailing list on 7th of February 2002 http://mail.python.org/pipermail/python-announce-list/2002-February/001228.…. Pypar has been used in many projects over the years but it became clear that relying on the Numeric was becoming a liability and many developers requested an upgrade to numpy. The update to version 2.0alpha signifies 1: Porting pypar to numpy instead of the discontinued Numeric module 2: Moving pypar to sourceforge: http://sourceforge.net/projects/pypar/ 3: Numerous improvements and optimisations added over the past years Version 2.0alpha has been tested on a few platforms, but I haven't been able to verify that it installs everywhere. The purpose of this post is to encourage existing and new users of pypar to try the new release and to get back to me with questions, feedback and patches that will allow pypar to run on as many platforms as possible. I am looking forward to hear from you Ole M. Nielsen Canberra, Australia Ole.Moller.Nielsen(a)gmail.com Background: ----------- The use of multi processor computers is becoming increasingly common and they appear in many forms: Desktop computers with more than one processor sharing memory, clusters of PC's connected with fast networks known as Beowulf clusters, and high-end super computers all make use of parallelism. Even playstations have been connected to form computational networks (http://arrakis.ncsa.uiuc.edu/ps2/cluster.php). To efficiently use these machines in a portable way one must be able to control communication among programs running in parallel. One such standard is the Message Passing Interface (MPI) for inter-processor communication. Python and MPI: --------------- There are a number of other Python bindings to MPI that are more comprehensive than pypar (PyMPI, Scientific Python). However, pypar stands out by not requiring the Python interpreter to be modified, by being very easy to install and by by shielding the user from many details involving data types and MPI parameters without sacrificing the full bandwidth provided by the underlying MPI implementation. Download: --------- Pypar can be downloaded from http://sourceforge.net/projects/pypar Credentials: ------------ Pypar was developed by Ole Nielsen at the Australian National University in 2001 for use in the APAC Data Mining Expertise Program and has been published under the GNU Public License (http://www.gnu.org/licenses/gpl.txt) Contact: Ole.Moller.Nielsen(a)gmail.com <Ole.Nielsen(a)anu.edu.au> <P><A HREF="http://sourceforge.net/projects/pypar" <http://datamining.anu.edu.au/pypar>>Pypar 2.0alpha</A> - A simple and efficient MPI binding for Python.

July 5, 2007 - The Zope 3 development team announces the Zope 3.4.0b1 release This release is the first beta release for Zope 3.4.0. It was preceeded by an alpha release in April. Since the beta we finished repackaging of eggs, added three new features and fixed more than 12 bugs, please see the change log for details. Zope 3.4 introduces support for binary large objects in the ZODB, provides a new postprocessing hook for publishing results and makes all Zope packages available as Python eggs. Development release and feedback -------------------------------- This is a development release with beta quality. It is intended for developers to check their applications for compatibility with the new features. This release *is not intended to be used in production environments*. We would love to hear about any bugs you encounter. Please use our bug tracker, the mailing lists, and the IRC channel to contact us in case you encounter any problems. This beta release will be succeeded by a release candidate which is expected to be available by August 5, 2007. For status updates on our roadmap check: https://launchpad.net/zope3/3.4/+milestones What is Zope 3? --------------- Zope 3 is a web application server that continues to build on the heritage of Zope.

itools 0.16.1 released
by "J. David Ibáñez" 05 Jul '07

05 Jul '07

itools is a Python library, it groups a number of packages into a single meta-package for easier development and deployment: itools.catalog itools.i18n itools.tmx itools.cms itools.ical itools.uri itools.csv itools.odf itools.vfs itools.datatypes itools.pdf itools.web itools.gettext itools.rest itools.workflow itools.handlers itools.rss itools.xhtml itools.html itools.schemas itools.xliff itools.http itools.stl itools.xml This is (mostly) a bug fix release: - The command line tool "rsync" is not required anymore. - Indexing of XML documents (like web pages) works again. - Now itools.web supports X_FORWARDED_PROTO, what makes possible to deploy web applications behind Apache (or another web server) using the HTTPS protocol. - Now itools.xml is able to serialize documents with CDATA sections. - In itools.stl the repeat variables "repeat/x/index", "repeat/x/start" and "repeat/x/end" work again. - The method "set_handler" works now when the container is a virtual handler. But most changes are in the itools.cms package: - The Quick Start is updated now, the "icms-make-package -t quickstart" command works again. - The new method "get_object" has been added to the itools.cms API. - An important bug has been fixed in the itools.cms database, where the incorrect usage of "mkstemp" made sometimes a transaction to fail because all files descriptors were used. - Now we correctly unindex the content of a folder when it is removed. - There are various fixes and improvements to the Calendar and Wiki objects. - The script "icms-update" has been improved in different ways. Most important, now it is possible to upgrade an itools.cms instance directly from 0.14 to 0.16 (no need to go through 0.15). Credits: - Hervé Cauwelier updated the Quick Start and fixed bugs; - Nicolas Deram worked on the Calendar object; - J. David Ibáñez fixed bugs; - Henry Obein fixed bugs; - Sylvain Taverne fixed bugs; Resources --------- Download http://download.ikaaro.org/itools/itools-0.16.1.tar.gz Home http://www.ikaaro.org/itools Mailing list http://mail.ikaaro.org/mailman/listinfo/itools Bug Tracker http://bugs.ikaaro.org/ -- J.
