[ANNOUNCE] gmpy 1.0 alpha released
by Alex Martelli 12 Nov '05

12 Nov '05

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

popen5: New POSIX process module
by Peter Astrand 03 Nov '03

03 Nov '03

I've written a new popen-like module for Python. This module overcomes several limitations with the old popen2 module, but also aims to be a generic module for starting and communicating with processes on POSIX systems. It can replace several older modules and functions, like: os.system os.spawn* os.popen* popen2.* commands.* This module features: * Cross-process exceptions: Exceptions happening in the child before the new process has started to execute are re-raised in the parent. This means that it's easy to handle exec() failures, for example. With popen2, it's impossible to detect if the execution failed. * A hook for executing customized code between fork and exec. This can be used for, for example, changing uid. * No implicit call of /bin/sh. This means that there is no need for escaping dangerous shell meta characters. * A communicate() method, which makes it easy to send stdin data and read stdout and stderr data, without risking deadlocks. * Support for connecting several subprocesses (shell "pipe"). The module is available from http://cvs.lysator.liu.se/viewcvs/viewcvs.cgi/popen5/?cvsroot=python-popen5, or via anonymous CVS (:pserver:anonymous@cvs.lysator.liu.se:/cvsroot/python-popen5). All feedback is appreciated. /Peter Åstrand <astrand(a)lysator.liu.se>

ANN: ClientForm 0.1.10 released
by jjl＠pobox.com 31 Oct '03

31 Oct '03

http://wwwsearch.sourceforge.net/ClientForm/ Changes from 0.1.9 to 0.1.10: * XHTML support (only for Pythons >= 2.2). Thanks to Michael Howitz. * A minor bugfix. Requires Python >= 1.5.2. ClientForm is a Python module for handling HTML forms on the client side, useful for parsing HTML forms, filling them in and returning the completed forms to the server. It has developed from a port of Gisle Aas' Perl module HTML::Form, from the libwww-perl library, but the interface is not the same. Simple example: from urllib2 import urlopen from ClientForm import ParseResponse forms = ParseResponse(urlopen("http://www.example.com/form.html")) form = forms[0] print form form["author"] = "Gisle Aas" # form.click returns a urllib2.Request object # (see HTMLForm.click_request_data.__doc__ if you're not using urllib2) response = urlopen(form.click("Thanks")) John

ANN: emkey 0.2 - a simple post-processing tool for Keynote documents
by Dinu Gherman 31 Oct '03

31 Oct '03

Hi, I've released emkey 0.2, a simple post-processing tool for Keynote documents. As of now it might be particularly useful for people using Python code on Keynote slides, but it's easy to imagine additional features. Please see the full Readme for this first release below. Regards, Dinu emkey ===== Summary ------- emkey is an EmPy-based post-processing tool for Apple Keynote documents. Overview -------- emkey is a simple command-line tool for post-processing Apple Keynote documents. It currently imports external text snippets on single slides and can apply syntax color highlighting to them if these are Python source code. Basics ------ emkey works on the APXL [1]_ presentation file of a Keynote [2]_ document. Before using it you create a normal Keynote presentation document. EmPy [3]_ tags like ``@load("fibo.py", colored=1)`` on a slide will then be expanded during post-processing by emkey with the content of the respective file, with syntax highlighting for Python code if desired. The tool makes one backup of the APXL file before modifying it, and allows to revert to this backup after post-processing. History ------- :0.2: first release Requirements ------------ There are no special requirements for running emkey, except a Python interpreter 2.x [4]_, EmPy 3.x (3.3 included), copyrighted by Erik Max Francis and PyFontify (0.5 included), copyrighted by Just van Rossum. Licence ------- emkey is released under the GPL - see the included file, "GPL.txt". The included EmPy and PyFontify modules are licensed under the LGPL and the Python License, respectively. Download -------- The emkey distribution, including one Keynote sample document is available from: http://python.net/~gherman/emkey.html Notes ------ Thanks to Erik Max Francis and Just van Rossum who have kindly allowed to include EmPy and PyFontify respectively into the emkey distribution. Note, that there is no installation procedure by which you might risk to overwrite an existing EmPy or PyFontify. **Be careful when using emkey on Keynote documents! Remember to revert to the original version before re-editing the document with Keynote, again!** Future ------ In principle one could extend this tool to provide further kinds of post-processing capabilities on Keynote files, which, of course, needs intimate knowledge of the APXL files.

Release of SalStat 20031022, standalone executables for Linux and Windows!
by alan_salmoni＠yahoo.com 26 Oct '03

26 Oct '03

This is a quick note to announce a release of SalStat, the Python/wxPython powered application for scientific statistical analysis. If you're not sure what this is: just think SPSS/StatView/SAS (but a bit more basic... for now!) The 2 new files are stand-alone executables (packaged with the McMillan installer, and Inno setup for Windows), which means that users should be able to use SalStat without having to download Python, wxPython and Numeric. Of course, the source code versions are also available from the website. This is the first Linux binary version for almost a year, and the first Windows binary for about 6 months... (sorry guys, had problems which are now sorted) The Linux version is about 8MB, and 4MB for Windows. The tar.gz file for the source code version is half a meg, but you'll need wxPython and Numeric installed. Also, I want to announce that I have moved most of the action from the SunSite website to SourceForge. The website is there (http://salstat.sourceforge.net) with all the usual details (though a few screenshots have yet to be uploaded). The download page is http://sourceforge.net/project/showfiles.php?group_id=16791. The project page is at http://sourceforge.net/projects/salstat/. I hope you are all well and enjoying programing in Python as much as I am! Alan James Salmoni SalStat Statistics
