Hi All, PyDev - Python IDE (Python Development Enviroment for Eclipse) version 0.9.8.2 has been released. Check the homepage (http://pydev.sourceforge.net/) for more details. Details for Release: 0.9.8.2 Major highlights: ------------------------ * Content assistants reviewed (and better documented on the homepage -- I really reccomend checking it) * Timeout parsing options added (this is available in the builder preferences page) * Auto-dedent added Others that are new and noteworthy: ----------------------------------------------------- * .pyc is removed when the corresponding .py file is removed. * Debugger has been changed so that it becomes faster (still not as fast as I would like, but still... faster) -- looking for people with expertise on this to help me, as I'm kind of lost on which should be the 'recommended' way to speed it more. * Some escaped quotes problems fixed when formatting code * Navigation with Ctrl+Shift+ (up or down) has been slightly improved, so that it goes to the start or the end of the file when no other class or method declaration is found * Other bug-fixes (as ususal) Cheers, Fabio -- Fabio Zadrozny ------------------------------------------------------ Software Developer ESSS - Engineering Simulation and Scientific Software www.esss.com.br PyDev - Python Development Enviroment for Eclipse pydev.sf.net pydev.blogspot.com

[ANNOUNCE] gmpy 1.0 alpha released

by Alex Martelli

See http://gmpy.sourceforge.net/ for details. What is it: a wrapper for the GMP library, to provide multi-precision arithmetic for Python. Multi-precision floats, and unbounded-precision rationals, are not present in stock Python; multi-precision integers ('long') are, but gmpy's version of multi-precision integers is faster for some operations (NOT all -- used to be, but Python 2.3 did serious enhancements to some operations on longs) and provides lots of nifty pre-packaged additional functions. Minor changes and bug-fixes since the latest 0.9 pre-alpha; support for Python 2.3. The Windows binary release is now for Python 2.3 _only_ (if you're stuck with Python 2.2 on Windows, you can keep using gmpy 0.9 pre-alpha and not really suffer from that). Known bug on Windows: the scan0 and scan1 functions appear broken (perhaps related to the lack of a GMP 4.0 library for Windows -- haven't found one around yet). Alex

SciPy Core (replacement for Numeric Python) first beta release

by Travis Oliphant

Background: Numeric is an add-on Python module that has seen widespread adoption. It enables Python to be used as a Scientific Computing Environment similar to MATLAB or IDL. Numeric was originally written nearly 10 years ago, and while still performing admirably, needed much updating to take advantage of the new features in Python and to remove old warts. SciPy Core 0.4.1 (beta) SciPy Core is a new system which builds on the code-base of Numeric, but implements features (such as advanced index-selection, and user-settable error modes). There are over 25 major new feature enhancements. The LICENSE is still a BSD style License---the same as old Numeric. More information can be found at the web-site: http://numeric.scipy.org The primary developer of scipy core (besides the original creators of Numeric upon which it is based) is Travis Oliphant (oliphant(a)ee.byu.edu), but his work received ideas and support from a wide cast of community members including: Pearu Peterson, Robert Kern, Perry Greenfield, Eric Jones, John Hunter, Fernando Perez, Konrad Hinsen, and Paul Dubois. These individuals should not be held responsible for any bugs remaining in the code. <P><A HREF="http://numeric.scipy.org">SciPy Core 0.4.1 (beta)</A> - Replacement for Numeric Python. (30-Sep-05)

FarPy GUIE v0.1

by dberlin＠gmail.com

GUIE (GUI Editor) provides a simple WYSIWYG GUI editor for wxPython. The program was made in C# and saves the GUI that was created to a XML format I called GUIML. This GUIML is a pretty standrad representation of the GUI created with the program. Next, GUIE takes these GUIML files and translates it to wxPython Python code. You may ask yourself why I took the extra step? Why didn't I go straight from C# controls to wxPython code? Why is GUIML neccessary? Well, it isn't. It is there simply for people (or maybe I) to take the GUIML and convert it to other languages. This, by affect can convert this tool from a Python GUI editor, to "any programming language with a GUI module" GUI editor. Changes: Fix: cast exception when editing form properties Fix: exception raised when GUI form too small Added: settings window functionality Added: controls: Progress Bar, Picture Box, Track Bar (Slider) Added: keyboard functionality (arrow movement and delete key) Fix: selection made when resizing GUI form Fix: control moved down when resized beyond its limit Changed: default foreground color to black Fix: Combo Box offset when moving Added: exit confirmation system Added: multi-selection system, enables moving and deleting (also removing/adding single control using the control key)

Vancouver Python and Zope: Next Meeting Oct 2nd

by Andy McKay

The Vancouver Python and Zope user groups next meeting is on Oct 4th, at the usual place, ActiveState at 7. Mishtu Banerjee will be giving a talked entitled "Desperately Seeking Abstraction" "I built an SQL query generator (as part of a larger project) based on the underlying abstraction of representing data models as "networks". It's a nice illustration of abstracting a particular analysis pattern (in this case, we're abstracting the pattern of multi-table inner joins, which is one of the most common ad-hoc query types)" For more information see our website: http://www.vanpyz.org Mailing list: http://www.agmweb.ca/cgi-bin/mailman/listinfo/list -- Andy McKay Enfold Systems, LLC http://www.enfoldsystems.com

[ANN] PyODB version 0.5 released

by Neil Moses

I would like to announce version 0.5 of PyODB a Python unixODBC API binding. This release contains improvements to the mapping between the SQL and Python datatypes and a re-write of the data retrieval code. Also some changes to the reference counting. PyODB is a Python module and provides a simplified set of bindings to unixODBC (http://www.unixodbc.org) allowing fast and easy development of open database applications. The module supports multiple data source connections with the following connection methods; execute(), fetch(), disconnect(), begin(), commit() and rollback(). The software has been developed on a Linux environment using Python 2.x and SWIG (http://www.swig.org). The module has been tested on Linux and Solaris platforms using databases MySQL, Informix and PostgreSQL but in theory should work on any platform supporting unixODBC and an ODBC database driver. To download the release visit http://sourceforge.net/projects/pyodb Regards, Neil Moses
