MayaVi-1.1 released.
by Prabhu Ramachandran Nov. 20, 2001

Nov. 20, 2001

Hi, This is to announce the availability of the MayaVi Data Visualizer version 1.1. MayaVi is a free, easy to use, scientific data visualizer. It is written in Python and uses the Visualization Toolkit (VTK) for the graphics. It provides a GUI written using Tkinter. MayaVi is free and distributed under the GNU GPL. It is also cross platform and should run on any platform where both Python and VTK are available. For more information, downloadable sources and *binaries*, screenshots, installation instructions, documentation etc. visit the MayaVi home page at: http://mayavi.sourceforge.net Also bundled with MayaVi is a VTK pipeline browser written in Python and a new utility module that makes using VTK easier from the interpreter. What's new in this release: (*) Binaries for Linux and Win32 made using Gordon McMillan's Installer. (*) MayaVi can now be used from other Python programs, can be scripted and can also be used interactively from the Python interpreter. For a specific example see: http://mayavi.sourceforge.net/docs/guide/c760.html (*) Installs as a Python package using distutils. (*) Command line arguments are now supported. (*) Added 3D Studio file import, RenderMan RIB/JPEG/PNG export. (*) Improved streamline module and better 2D streamlines. (*) More options to place the vector glyphs for vector plots. (*) Added filters: PolyDataNormals, WarpVector, WarpScalar, ExtractUnstructuredGrid. Added module: WarpVectorCutPlane. (*) New VtkData class that handles user constructed vtk data. (*) Added basic tensor support, a tensor related filter and module. Contributed by Jose Paulo <moitinho(a)civil.ist.utl.pt> -- many thanks! (*) Huge speed up (by a factor of 50 or more) in the "expand all" feature of the pipeline browser, many thanks to Dan Blezek <blezek(a)crd.ge.com> for this! (*) New utility module, ivtk.py, that makes interactive VTK a pleasure. More information on this module is available at: http://mayavi.sourceforge.net/docs/guide/x799.html (*) Intelligently disable annoying VTK warning messages. Various bugs have been fixed and other small enhancements have been made. Have fun! prabhu

ANNOUNCE: Optik 1.1 released
by Greg Ward Nov. 17, 2001

Nov. 17, 2001

Optik 1.1 ========= Optik is a powerful, flexible, extensible, easy-to-use command-line parsing library for Python. Using Optik, you can add intelligent, sophisticated handling of command-line options to your scripts with very little overhead. Here's an example of using Optik to add some command-line options to a simple script: from optik import OptionParser [...] parser = OptionParser() parser.add_option("-f", "--file", action="store", type="string", dest="filename", help="write report to FILE", metavar="FILE") parser.add_option("-q", "--quiet", action="store_false", dest="verbose", default=1, help="don't print status messages to stdout") (options, args) = parser.parse_args() With these few lines of code, users of your script can now do the "usual thing" on the command-line: <yourscript> -f outfile --quiet <yourscript> -qfoutfile <yourscript> --file=outfile -q <yourscript> --quiet --file outfile (All of these result in options.filename == "outfile" options.verbose == 0 ...just as you might expect.) Even niftier, users can run one of <yourscript> -h <yourscript> --help and Optik will print out a brief summary of your script's optons: usage: <yourscript> [options] options: -h, --help show this help message and exit -fFILE, --file=FILE write report to FILE -q, --quiet don't print status messages to stdout That's just a taste of the flexibility Optik gives you in parsing your command-line. See the documentation included in the package for details. AUTHOR, COPYRIGHT, AVAILABILITY ------------------------------- Optik was written by Greg Ward <gward(a)python.net> The latest version of Optik can be found at http://optik.sourceforge.net/ Copyright (c) 2001 Gregory P. Ward. All rights reserved. CHANGES IN OPTIK 1.1 -------------------- * Changed OptionParser.parse_args() method to allow interspersed options and positional arguments by default; can be disabled with disable_interspersed_args() method. Reorganized the guts of the OptionParser class fairly heavily. * Split test_optik.py up into three scripts (test_optik, test_callback, and test_extend), and moved them all into the test/ directory. * Added the 'nargs' attribute to Option, which allows options to require more than one argument on the command line. This enables eg. parser.add_option("-p", "--point", action="append", nargs=3, type="float", dest="points") to turn a command-line like this: --point 3.4 -5 95 -p 4 -4 6 into this: options.points == [(3.4, -5.0, 95.0), (4.0, -4.0, 6.0)] * Fixed so the last default value explicitly specified for a particular option destination takes precedence, even if it's None. -- Greg Ward - Unix bigot gward(a)python.net http://starship.python.net/~gward/ Vote Cthulhu -- why settle for a lesser evil?

RELEASED: Python 2.2b2 is out!
by barry＠zope.com Nov. 16, 2001

Nov. 16, 2001

Today we release Python 2.2b2, the second -- and probably last -- beta release of Python 2.2, for your enervation, elocution, and effervescence. http://www.python.org/2.2/ Our thanks to everyone who is testing out these beta releases! Please continue to report any bug you find to the bug tracker: http://sourceforge.net/bugs/?group_id=5470 Highlights of what's new for this release are outlined below. For a more complete list, please see: http://sf.net/project/shownotes.php?release_id=61669 Andrew Kuchling is writing a gentle introduction to the most important changes, titled "What's New in Python 2.2": http://www.amk.ca/python/2.2/ Guido's written his own introduction to the type/class unification at: http://www.python.org/2.2/descrintro.html python-is-so-proud-of-little-brother-orlijn-ly y'rs, -Barry -------------------- snip snip -------------------- - Lots of bug fixes! - Multiple inheritance mixing new-style and classic classes in the list of base classes is now allowed. - The new builtin dictionary() constructor, and dictionary type, have been renamed to dict. This reflects a decade of common usage. - dict() now accepts an iterable object producing 2-sequences. For example, dict(d.items()) == d for any dictionary d. The argument, and the elements of the argument, can be any iterable objects. - New-style classes can now have a __del__ method, which is called when the instance is deleted (just like for classic classes). - Assignment to object.__dict__ is now possible, for objects that are instances of new-style classes that have a __dict__ (unless the base class forbids it). - The socket function has been converted to a type; see below. - Assignment to __debug__ raises SyntaxError at compile-time. This was promised when 2.1c1 was released as "What's New in Python 2.1c1". - mmap has a new keyword argument, "access", allowing a uniform way for both Windows and Unix users to create read-only, write-through and copy-on-write memory mappings. - By default, the gc.garbage list now contains only those instances in unreachable cycles that have __del__ methods. - The socket module defines a new method for socket objects, sendall(). - Symbolic group names in regular expressions must be unique. - We've finally confirmed that this release builds on HP-UX 11.00, *with* threads, and passes the test suite. - Thanks to a series of patches from Michael Muller, Python may build again under OS/2 Visual Age C++. - Updated RISCOS port by Dietmar Schwertberger.

Nov. 15, 2001

NEW RELEASE The new release of DBDoc features Oracle support in addition to the existing PostgreSQL support. DESCRIPTION If you have ever wanted javadoc-style HTML documentation for your database schemas, or a consistent way of programatically inspecting a database schema, then DBDoc may be of interest to you. This small project defines a simple Python API for inspecting database schemas, and uses it to generate documentation (optionally incorporating descriptive text placed in an auxiliary file). (Implementations of the schema introspection API for other databases would be most welcome.) FURTHER INFORMATION Homepage: http://dbdoc.sourceforge.net/ Download: http://sourceforge.net/project/showfiles.php?group_id=34872 Licence: BSD Best wishes to all, -Steve -- Steve Purcell, Pythangelist Get testing at http://pyunit.sourceforge.net/

ANNOUNCE: Quixote 0.4.2 released
by Greg Ward Nov. 13, 2001

Nov. 13, 2001

Quixote 0.4.2 is now available for download from: http://www.mems-exchange.org/software/quixote/ Quixote is yet another framework for developing Web applications in Python. The design goals were: 1) To allow easy development of Web applications where the accent is more on complicated programming logic than complicated templating. 2) To make the templating language as similar to Python as possible, in both syntax and semantics. The aim is to make as many of the skills and structural techniques used in writing regular Python code applicable to Web applications built using Quixote. 3) No magic. When it's not obvious what to do in a certain case, Quixote refuses to guess. If you view a web site as a program, and web pages as subroutines, Quixote just might be the tool for you. If you view a web site as a graphic design showcase, and each web page as an individual work of art, Quixote is probably not what you're looking for. Quixote was primarily written by Andrew Kuchling, Neil Schemenauer, and Greg Ward ({akuchlin,nascheme,gward}(a)mems-exchange.org). CHANGES in Quixote 0.4.2 ------------------------ * Made the quixote.sendmail module a bit more flexible and robust. * Fix so it doesn't blow up under Windows if debug logging is disabled (ie. write to NUL, not /dev/null). * Clarified some documenation inconsistencies, and added description of logging to doc/programming.txt. * Fixed some places that we forgot to update when the PTL- related modules were renamed. * Fixed ptl_compile.py so PTL tracebacks include the full path of source file(s). * Fixed bug where a missing _q_index() triggered a confusing ImportError; now it triggers a TraversalError, as expected. * Various fixes and improvements to the Config class. * Miscellaneous fixes to session.py. * Miscellaneous fixes to widget classes. -- Greg Ward - software developer gward(a)mems-exchange.org MEMS Exchange http://www.mems-exchange.org
