by Ferenczi Viktor 11 Jul '07

11 Jul '07

This is an enhanced version of python-cjson, the _fast_ JSON encoder/decoder for python. Bugfix: - Fixed segmentation fault when decoding specially crafted unicode strings. I recommend you to upgrade python-cjson, since a critical bug has been fixed. All existing and new unit tests are passed with python 2.3.5, 2.4.3 and 2.5.1 without problems. Windows installer for Python 2.5.1 included. Download, examples and more information: http://python.cx.hu/python-cjson

bbfreeze 0.95.1
by Ralf Schmitt 11 Jul '07

11 Jul '07

Hi all, I've just uploaded bbfreeze 0.95.1 to python's cheeseshop. bbfreeze creates standalone executables from python scripts. It's similar in functionality to py2exe or cx_Freeze. This release fixes some problems with egg files and with some of the recipes. *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.

Try a different type of debugger.
by mfriedeman＠gmail.com 11 Jul '07

11 Jul '07

This one does not need you to set any breakpoints. It records the entire run. Handy, if you don't know where to start. Run the program once and after that all the runtime data is available to you. Which means you can jump to any point in the run and verify the code against runtime data. The user interface is the python code itself viewed inside a Firefox browser. Scroll to a line you're interested in and click the variable. It requires Firefox and Python 2.5. http://codeinvestigator.googlepages.com/main

PyGTK Introduction @ Toronto Area Python User's Group Meeting next Tuesday
by Mike C. Fletcher 10 Jul '07

10 Jul '07

Our topic for the next PyGTA meeting is the PyGTK binding to the Open Source GTK+ GUI library. Myles Braithwaite, a local developer and consultant will be presenting an introduction to the library including how to get started programming with it. Myles has used GTK, among other things, to develop a pair of games for the OLPC laptop. GTK is reasonably portable Free software that has a number of GUI-layout tools, with the Glade system being the most well-known among them. We'll be meeting at our regular venue, Linux Caffe, which is open until 11pm for the summer, affording us a much more relaxed pace for our meetings. We'll plan to start the presentation for 7:15pm, with people encouraged to gather at 7:00 to chat and socialise. Linux Caffe is at the corner of Grace and Harbord streets, 1 block South of Christie station. Free WiFi is available, as are snacks and sandwiches, ice cream, smoothies, coffee, tea and the like. Details on how to get to Linux Caffe are available on the PyGTA next-meeting page: http://www.pygta.org/ Have fun all, Mike -- ________________________________________________ Mike C.

New release: Crunchy 0.9
by Andre 09 Jul '07

09 Jul '07

Crunchy 0.9 has been released. It is available at http://code.google.com/p/crunchy What is Crunchy? Crunchy is a an application that transforms html Python tutorials into interactive session viewed within a browser. We are not aware of any other application (in any language) similar to Crunchy. Currently Crunchy has only been fully tested with Firefox; we know that some browsers simply don't work with it. Crunchy should work with all operating systems - it has been tested fairly extensively on Linux, Windows and Mac OS. What is new in this release? Crunchy has been rewritten from scratch from the previous version (0.8.2), to use a custom plugin architecture. This makes easier to extend and add new functionality. Rather than list the differences with the old release, it is easier to list the essential features of this new version. 1. Crunchy can work best with specially marked-up html tutorials. However, it can now work with any html tutorials - including the official Python tutorial on the python.org site. Html pages can be loaded locally or remotely from anywhere on the Internet. Crunchy uses a combination of Elementtree and BeautifulSoup to process html pages. Non W3C-compliant pages can be handled, but the visual appearance is not guaranteed to reproduce that normally seen using a browser. 2. Crunchy can insert a number of Python interpreters inside a web page. In the default mode, it does that whenever it encounters an html <pre> element which is assumed to contain some Python code. These interpreters can either share a common environment (e.g. modules imported in one of them are known in the other) or be isolated one from another. 3. Crunchy adds automatic css styling to the Python code - you can look at the official Python tutorial using your browser (all Python code in blue) and compare with what Crunchy displays to give you a good idea. 4. Instead of inserting an interpreter, Crunchy can insert a code editor that can be used to modify the Python code on the page and execute it. The editor can be toggled to become a fairly decent syntax aware editor that can save and load files. 5. Crunchy has a "doctest" feature where the code inside the <pre> is taken to be the result of an interpreter session and the user has to write the code so as to make the interpreter session valid; this is useful in a teaching environment. Messages from the Crunchy's doctest are "friendlier" for Python beginners than the usual tracebacks. 6. Crunchy has a small graphics library that can be imported, either inside an editor or an interpreter, to produce simple graphics (even animations!) inside the browser. 7. For the user that needs better quality graphics, Crunchy supports programs (such as matplotlib) that can create image files; by executing the code, the image produced is loaded inside the browser window. In this capacity, Crunchy could be used as a front end for libraries such as matplotlib. 8. Crunchy supports code execution of files as separate processes, making it suitable to launch gui based application from the browser window. 9. Crunchy's interpreter has an interactive "help" feature like many python-aware IDEs. 10. Crunchy includes a fairly comprehensive tutorial on its own use, as well as a reference for tutorial writers that want to make their tutorials "crunchy-friendlier". 11. As a security feature, crunchy strips all pre-existing javascript code from an html page before displaying it inside the browser window. Bug reports, comments and suggestions are always welcome. André Roberge, for the Crunchy team.
