Mailman 3 October 2003 - Python-announce-list

Toronto-area Python user group, Tuesday October 28, 8pm
by Peter Hansen Oct. 21, 2003

Oct. 21, 2003

The next monthly meeting of PyGTA, the Toronto-and-area Python user group, will be held next week at the usual time and place: - Tuesday, October 28 - from 8 pm to 10 pm - room 31 of the 519 Church St Community Centre No specific speakers are lined up yet, although I will probably be demonstrating Kaval's unittest-based test framework for the HC12 CPU, which allows tests written in Python to verify code written in C and compiled to machine code for this chip, using a CPU simulator written in Python. The usual post-meeting sugar-and-caffeine fest will occur at Just Desserts on Yonge. Last meeting had a near record turnout, with much interesting discussion, so don't miss out... see you there! -Peter and Ian, meeting organizers P.S.: Out of consideration for the high volume of the comp.lang.python newsgroup and the mailing list, this will be the last announcement posted there. Subsequent ones will go only to the .announce group and the pygta-announce mailing list. Unless we get enough requests to the contrary... if you've been hearing these announcements only through c.l.p or the Python list, now's the time to subscribe to our PyGTA announcement mailing list: see http://web.engcorp.com/pygta/wiki/MailingLists for more.

PyRAF 1.1 now available
by Perry Greenfield Oct. 20, 2003

Oct. 20, 2003

The Science Software Branch of the Space Telescope Science Institute wishes to announce the availability of version 1.1 of PyRAF. PyRAF is intended to be used with the astronomical data reduction system called IRAF (http://iraf.noao.edu) PyRAF allows one to run IRAF tasks from within a Python interpreter. IRAF CL syntax can be used interactively from within PyRAF, and a number of new interactive features are provided (notably command line recall). It also allows Python to be used to script IRAF tasks. See the PyRAF home page for more information. http://www.stsci.edu/resources/software_hardware/pyraf The primary change in this version (from 1.0) is that it uses a different default graphics kernel that removes the dependence on the software components that have proved the most difficult to install and maintain, namely those items related to OpenGL. It is the first version of PyRAF that works on Mac OS X. This release includes upgraded versions of numarray and PyFITS, as well as a new module (numdisplay) that allows displaying numarray arrays on x11iraf or ds9 (or any compatible image display program). Also included are two new utilities: readgeis, which can read GEIS files into numarray, and fitsdiff which compares the headers and data of two different FITS files. See the PyRAF web page (use link below) for more details on all of these modules and packages. Some tasks in STSDAS 3.1 (released concurrently) require PyRAF 1.1. Users using these tasks (e.g., PyDrizzle) must upgrade from PyRAF 1.0. Furthermore, PyDrizzle in STSDAS 3.0 will not work with PyRAF 1.1; users will need to upgrade to STSDAS 3.1 to use PyDrizzle with PyRAF 1.1. PyRAF 1.1 is supported on Solaris, Redhat Linux, and Mac OS X. It should work on other Unix and Linux systems though it has not been tested by us on those platforms, and support for debugging problems may be limited (and effectively nonexistent for some platforms, such as Tru64, AIX, and IRIX). Unlike previous releases, this release does not include binary distributions and will need to be built from source; this should be straightforward now that dependencies on OpenGL have been removed. If feedback indicates that source installations are too difficult or problem-prone on some platforms, will provide binary distributions for those as needed. Please contact help(a)stsci.edu if any difficulties are encountered with installation. It may be downloaded from http://www.stsci.edu/resources/software_hardware/pyraf/current/download This release also fixes a number of bugs and makes some small changes in functionality. Consult the release notes for details. PyRAF is released with an OpenSource BSD license.

ANN: Leo 4.0 final: An outlining editor
by Edward K. Ream Oct. 20, 2003

Oct. 20, 2003

Leo 4.0 is now available at: http://sourceforge.net/projects/leo/ More than a year in the making, Leo 4.0 is here. Highlights of 4.0 final: ----------------------- ** Improved and simplified format of derived files. - Eliminated child indices, extra blank lines and @body sentinels. - Eliminated @node sentinels that indicate outline structure. - New @nl and @nonl sentinels indicate where newlines are. - These changes largely eliminate unwanted cvs conflicts. ** Greatly improved error handling. - Reading derived files _never_ alter outline structure or links. - Read errors leave the outline completely unchanged. - Broken clone links are gone forever. - As a result, 4.0 is much safer than all previous versions. ** Full compatibility will previous versions of Leo. - Leo 4.0 reads all derived files properly, regardless of version. - Leo writes new-format derived files by default. - New commands in the read/write menu allow you to explicitly specify the format of derived files. * New commands: - Write 3.x Derived File and Write 4.x Derived File. - Import Derived File. - Clear Recent Files. * Dozens of other improvements, including: - Better Unicode support. - New configuration settings. - Several new plugins. Quote of the month ------------------ I've written documentation in WordPerfert, Ventura, Word, PageMaker, and FrameMaker and even though they create wonderfully looking and useful documents, they've never been able to do what I've been looking for. HTML, compiled help files, and later PDF came closer, but still not there. I think I've found it in Leo, a way to make a "living" document...A document built out of discrete parts that can be re-organized on the fly to meet the needs of a varying audience. Being a convert for less than a day I've still got a lot to learn, but just the possibility of keeping system maintenance scripts in the IT manual is mind boggling. -- David Nichols What is Leo? ------------ - A programmer's editor, an outlining editor and a flexible browser. - A literate programming tool, compatible with noweb and CWEB. - A data organizer and project manager. Leo provides multiple views of projects within a single outline. - Fully scriptable using Python. Leo saves its files in XML format. - Portable. leo.py is 100% pure Python. - Open Software, distributed under the Python License. Leo requires Python 2.1 or above and tcl/tk 8.3 or above.

Hello all, I've just setup a little python implementation (a simple server class and a client test program) of XMLRPC calls over a Jabber transport. Error handling is non-existant, so is documentation. You'll find it at http://pyhacks.suddenthinks.com/jabberrpc/ Any comment will be appreciated, as usual.

[ANNOUNCE] Tenth release of PythonCAD now available
by Art Haas Oct. 14, 2003

Oct. 14, 2003

I'd like to announce the tenth development release of PythonCAD, a CAD package for open-source software users. As the name implies, PythonCAD is written entirely in Python. The goal of this project is to create a fully scriptable drafting program that will match and eventually exceed features found in commercial CAD software. PythonCAD is released under the GNU Public License (GPL). PythonCAD requires Python 2.2 or Python 2.3. The interface is GTK 2.0 based, and uses the PyGTK module for interfacing to GTK. The design of PythonCAD is built around the idea of separating the interface from the back end as much as possible. By doing this, it is hoped that both GNOME and KDE interfaces can be added to PythonCAD through usage of the appropriate Python module. Addition of other interfaces will depend on the availability of a Python module for that particular interface and developer interest and action. The tenth release contains many fixes for running PythonCAD on Python 2.3. The latest Python release has a variety of internal changes, and various bits of code in PythonCAD triggered deprecation warnings from Python. All known warnings have been removed, so PythonCAD should run cleanly on this new Python release, as well as the older 2.2 releases. This release also includes the code for reading AutoCAD DWG files, though PythonCAD still is unable to import the files. This code will be the basis for importing DWG files into PythonCAD directly. A number of entity clipping algorithms have been added for use in redrawing the screen and future use in improving the internal entity storage and access. Radial dimensions entities now can display the diameter value of a circle instead of just the radius. This release also contains a number of other small bug fixes and code improvements, though the redraw bug in release eight is still not fixed. The DWG file format information came from the OpenDWG group, so my thanks to them for providing this information on the web. The OpenDWG website is at http://www.opendwg.org The mailing list for the development and use of PythonCAD is available. Visit the following page for information about subscribing and viewing the mailing list archive: http://mail.python.org/mailman/listinfo/pythoncad Visit the PythonCAD web site for more information about what PythonCAD does and aims to be: http://www.pythoncad.org/ Come and join me in developing PythonCAD into a world class drafting program! Art Haas -- Man once surrendering his reason, has no remaining guard against absurdities the most monstrous, and like a ship without rudder, is the sport of every wind. -Thomas Jefferson to James Smith, 1822
