Shed Skin Optimizing Python-to-C++ Compiler 0.0.10

by Mark Dufour

Hi all, I have just released version 0.0.10 of Shed Skin, an optimizing Python-to-C++ compiler. It allows for translation of pure (unmodified), implicitly statically typed Python programs into optimized C++, and hence, highly optimized machine language. Many non-trivial benchmarks (ray tracer, chess player, othello player, sat solver, 3 sudoku solvers..) run typically 2-40 times faster than when using Psyco, 12 times on average, and 2-220 times than when using CPython, 45 times on average. Besides many bug fixes, this release adds many error messages for unsupported features, so it should be much easier to try out the compiler and work around problems. Please download this new release from http://mark.dufour.googlepages.com and let me know about any problems/successes. Thanks, Mark Dufour. -- if vars: self.output('; '.join([self.type(var)+' '+name for (name,var) in vars.items()])+';')

lxml 1.1.2 released

by Stefan Behnel

Hi everyone, after a month of bug tracing and fixing, lxml 1.1.2 finally made it to the cheeseshop. http://cheeseshop.python.org/pypi/lxml This is mainly a bugfix release for the stable and production-ready 1.1 series, the changelog is below. As there were a number of important fixes, updating is recommended. What is lxml? """ lxml is a Pythonic binding for the libxml2 and libxslt libraries. It provides safe and convenient access to these libraries using the ElementTree API. It extends the ElementTree API significantly to offer support for XPath, RelaxNG, XML Schema, XSLT, C14N and much more. Lxml also features a sophisticated API for custom element classes. This is a simple way to write arbitrary XML driven APIs on top of lxml. There is a separate module lxml.objectify that implements a data-binding API on top of lxml.etree. """ See the web page for more information and documentation: http://codespeak.net/lxml/ Have fun, Stefan 1.1.2 (2006-10-30) Features added * Data elements in objectify support repr(), which is now used by dump() * Source distribution now ships with a patched Pyrex * New C-API function makeElement() to create new elements with text, tail, attributes and namespaces * Reuse original parser flags for XInclude * Simplified support for handling XSLT processing instructions Bugs fixed * Parser resources were not freed before the next parser run * Open files and XML strings returned by Python resolvers were not closed/freed * Crash in the IDDict returned by XMLDTDID * Copying Comments and ProcessingInstructions failed * Memory leak for external URLs in _XSLTProcessingInstruction.parseXSL() * Memory leak when garbage collecting tailed root elements * HTML script/style content was not propagated to .text * Show text xincluded between text nodes correctly in .text and .tail * 'integer * objectify.StringElement' operation was not supported

ANN: Porcupine Web Application Server 0.0.8 released

by t.koutsovassilis＠gmail.com

The brand new version of Porcupine introduces quite a few new cool features and many improvements that ease and accelerate the development process. Our main goal was to remove any constraints that expect the files of a Porcupine application to reside inside more than one folder tree. As a result, it is now attainable to develop your application working inside a single folder tree only. The application object was greatly simplified. The application's UI XML definition along with its script are now external files instead of having them embedded inside the object. This way, you can easily edit these files using your favourite editor. Additionally, the Porcupine desktop includes a new utility called HyperSearch. Use this utility to search the entire Porcupine database for objects that meet specific criteria such as text parts contained in their title or description and their modification date. The QuiX engine includes a completely rewritten event subsystem, in order to achieve a unified way of attaching and detaching DOM and custom event handlers. Furthermore, QuiX is now compatible with Internet Explorer 7 including many performance enhancements. Two new widgets are also added to the list of available widgets. An IFrame widget that enables the display of external sites inside the Porcupine desktop, and a group box. Enjoy.

ANN: xmlbuilder - XML generator

by Gerard Flanagan

An XML generator: http://gflanagan.net/site/python/utils/xmlbuilder/ A single file: 'xmlbuilder.py'. The real work is done by the XmlWriter class from the ElementTree package. If you're on 2.5, then you'll need to get the file 'SimpleXMLWriter.py' from http://effbot.org/zone/element-index.htm and save it somewhere in your PYTHONPATH, eg. site-packages. Then change the import line in xmlbuilder.py : change from elementtree.SimpleXMLWriter import XMLWriter to from SimpleXMLWriter import XMLWriter ---------------------------------------------------------------------------- >>> xml = XmlFragment() >>> root = xml.div() >>> print root <_XmlElement div> >>> print xml <div /> >>> firstchild = root.p("Some text", id="1") >>> print xml <div><p id="1">Some text</p></div> >>> firstchild.br() <_XmlElement br> >>> print xml <div><p id="1">Some text<br /></p></div> >>> firstchild.add_text("more text, ") <_XmlText> >>> print xml <div><p id="1">Some text<br />more text, </p></div> >>> firstchild.add_text("and more.").br() <_XmlElement br> >>> print xml <div><p id="1">Some text<br />more text, and more.<br /></p></div> >>> root.add_comment("COMMENT") <_XmlComment> >>> print xml <div><p id="1">Some text<br />more text, and more.<br /></p> </div> ---------------------------------------------------------------------

ANN: SPE 0.8.3.c Python IDE editor

by SPE - Stani's Python Editor

This is a maintenance release (mostly bug fixing) to prove that SPE is alive and well! In case you are using wxPython2.7 you'll need to upgrade to this release. Submitted patches will be reviewed and included if approved for next release. Thanks for all your patient support and continuing donations. The SPE 0.8.2.a release got downloaded 110550 times on berlios and sourceforge together. Not bad. This means SPE has not seen an update for a while or is getting very popular. Maybe both ;-) Installers are available for python 2.3, 2.4 and 2.5 for Windows and as a rpm including wxPython. Other operating systems can choose the no-setup.zip or targ.gz archives. A .deb archive is being prepared for Debian Linux systems such as Ubuntu. wxGlade is unfortunately not compatible with wxPython2.7. So if you want to use, you'll need wxPython2.6. :**Fixes**: - output is now done with a fixed font - uml.py is now again a stand alone demo - upgraded and fixed wxGlade - fixed for wxPython2.7 (and still backwards compatible with wxPython2.6) - updated NotebookCtrl :**Contributors**: - Andrea Gavana (NoteBookCtrl) - Alberto Griggio (wxGlade) - Michael Foord (python 2.3 + 2.5 releases for windows) :**Donations**: The development of SPE is driven by donations.
