Zope Weekly News - Wed, 28 Jul 1999
by Amos Latteier 28 Jul '99

28 Jul '99

Hello, The big news this week was the release of Zope 2.0 beta one. Zope 2 final is getting closer and closer. Beta one increases stability over the alpha releases and also adds a few missing pieces like the ability to tie permissions to factories. Also you can now export Zope objects to XML. Speaking of XML, as of beta one all basic Zope objects support a subset of the DOM Element interface, and the unsupported XML Document product is out and in CVS. * Zope 2.0 beta one was released this week. Now you can download a binary release of Zope 2. http://www.zope.org/Download/Releases/Zope-2.0.0b1 * The Zope site received a look and feel makeover. Most people seem to like the new design. A couple people posted describing the strange feeling of having the entire site change while browsing it. Zope sessions are cool! http://www.zope.org/pipermail/zope/1999-July/007368.html * Amos Latteier announced the availability of XML Document 1.0a1 a Zope product for using XML. A couple days later, XML Document made it into public CVS. http://www.zope.org/pipermail/zope/1999-July/007126.html http://www.zope.org/Download/XMLDocument http://www.zope.org/pipermail/zope-dev/1999-July/000990.html * Anthony Pfrunder announced a new version of his Zope for windows distribution. http://www.zope.org/pipermail/zope/1999-July/007189.html * Michel Pelletier announced Zippy Tag which allows you to insert random Zippy the Pinhead quotes in your Zope documents. Yes! http://www.zope.org/pipermail/zope/1999-July/007190.html http://www.zope.org/Download/Contrib/Zippy.tgz * Paul Everitt discusses how you can now export Zope objects to XML. Basically the XML format describes Python pickles. http://www.zope.org/pipermail/zope/1999-July/007200.html * Michel Pelletier posted an extremely simple summary of how to hook a form to a database. This is a good read for those new to Zope. http://www.zope.org/pipermail/zope/1999-July/007336.html * Andreas Kostyrka posted a patch to allow Zope to server multiple sites from one process. Very interesting, multiple sites from one object database! http://www.zope.org/pipermail/zope-dev/1999-July/000931.html http://www.mtg.co.at/projects/subhosting/ * Eric Kidd posted a Zope/XML-RPC todo list. Follow up posts confirmed that a number of the items have already been done. http://www.zope.org/pipermail/zope-dev/1999-July/000972.html * Brian Lloyd posted an insightful message describing the 'Owner' role and how to use proxy roles to allow limited access to restricted functions. http://www.zope.org/pipermail/zope-dev/1999-July/000987.html * Chris Petrilli mentioned that Gadfly is finally being updated to the latest version. Alright! http://www.zope.org/pipermail/zope-dev/1999-July/001002.html See you next week, same time, same channel. -Amos == Amos Latteier mailto:amos@digicool.com Digital Creations http://www.digicool.com -- ----------- comp.lang.python.announce (moderated) ---------- Article Submission Address: python-announce(a)python.org Python Language Home Page: http://www.python.org/ Python Quick Help Index: http://www.python.org/Help.html ------------------------------------------------------------

codeplot
by Dinu C. Gherman 28 Jul '99

28 Jul '99

Codeplot This is something like a toy example for Piddle that you might use as well to visually fingerprint Python code in a weird way, a bit like in the "Matrix", perhaps. ;-) Introduction (from codeplot's doc string): This module takes a Python source code file and creates a two-dimensional plot out of it. The plot generated is a symmetrical one, much like a 2D matrix where a dot at (i,j) indicates that lines i and j in the input file are the same. Sounds silly? Maybe, yes. After all, this is a one day fun 'project' while reading a book on, you guessed it, patterns. But I guess you'll be surprised of what you can see in these silly plots. Peaks result by definition from identical lines (in red). Very often this will be the case due to empty lines, therefore these lines are marked distinctly (grey). Other interesting things come from lines that are similar, but not identical. In the current implementation, "similar" means lines that are identical modulo an arbitrary inden- tation (marked in blue). So this is a little bit only of a bias towards Python as a language, but in fact you can run codeplot on any kind of ASCII file (that is made of individual lines, separated by newlines). The plots are generated using the new PIDDLE interface (during development codeplot created PDF files) in the version 1.0.3. Some words of praise for PIDDLE: it's cool! Without it codeplot would never have happened. What's the future of this thing?! I don't know! I'll do a bit more here and there, maybe create a proper EPS file instead of PDF (such that it can be included some- where else more easily). There's likely still something to improve to handle indentation by tabs properly as well. It could be faster, perhaps, but it's inherently O(n^2), so don't use it on a 200 KB C file (yes - they DO exist, sigh...). Using Numeric might be an idea, not sure... If you think you can do something to improve it let me know. If you use it in some interesting way, let me know, too. Installation: Put codeplot.py somewhere in your Python path. Also make sure you have Piddle already installed. You can find Piddle here: http://www.strout.net/python/piddle/ Files: README.txt - This file. codeplot.py - The Python codeplot module. samples.zip - Some sample PDF files. The samples were more or less randomly selected from the following packages: pythondoc, idle, pdfgen, piddle, consdiag, Zope, the Python Interpreter (a C file) and codeplot itself (the filenames should suffice to get an idea of where they awere taken from). The original python files are not included, though (except codeplot.py). Several differences can be observed, but these are to be explained elsewhere. Contact: Author: Dinu C.

Agrepy 1.0: Python port of agrep string matching with errors
by Michael Wise 28 Jul '99

28 Jul '99

<A HREF="http://glimpse.cs.arizona.edu/software.html">agrep</A> is a suite of command-line (i.e. UNIX user level) string matching functions, written by Sun Wu and Udi Manber (described in "Fast Text Searching Allowing Errors", CACM, 35(10), 1992). While the majority of the functionality is already found in Python, the ability to perform string searches accepting a limited number of errors has not been available till now. Such searches are able to deal, for example, with spelling errors, or the differences between North American and British English. Alternatively, this form of string matching is able to model the attachment of a primer to a target DNA sequence (i.e. attachment occurs if there are no more than, say, 2 indels). <A HREF="http://www.ccsr.cam.ac.uk/~michaelw/pyagrep.html">agrepy 1.0</A> - Python interface to the <A HREF="http://glimpse.cs.arizona.edu/software.html">agrep</A> approximate string matching implementation.

Updated compile tools for egcs/mingw32
by kernr＠mail.ncifcrf.gov 27 Jul '99

27 Jul '99

Hello all, compmgw.py and makemgw.py are Python scripts that ease the compilation of Python extensions on Win32 using the free egcs 1.1.2 compiler on the i386-mingw32 target. compmgw.py processes a Setup file and generates a Makefile that will compile your extension. makemgw.py processes a Setup file but runs the compiler commands itself and bypasses the Makefile. It uses a very simple (and probably inefficient and wrong) dependancy checker to generate the list of commands to run. WARNING: The code in both of these modules is incredibly bad. "hacks upon hacks upon hacks" sums up the state of these scripts pretty well. Do not read them if you have a heart condition. *Please* don't use them for anything else. Instead join the distutils-SIG and work with them to create a general mechanism. Both of these scripts will be dropped unceremoniously once the distutils-SIG gets far enough in its work. The scripts are available separately: * http://starship.python.net/crew/kernr/mingw32/compmgw.py * http://starship.python.net/crew/kernr/mingw32/makemgw.py or together with other tools: * http://starship.python.net/crew/kernr/mingw32/Py-mingw32-tools.zip Robert Kern <A HREF="http://starship.python.net/crew/kernr/mingw32/Notes.html"> Updated compile tools for egcs/mingw32</A> - updated scripts to parse Setup files for compiling on Win32 systems with egcs/mingw32.

seqdict 0.0 - 2 sequential dictionary emulations
by Wolfgang Grafen 27 Jul '99

27 Jul '99

26.7.1999 http://www.germany.net/teilnehmer/100,366919/Python/Modules/Modules.html Package seqdict Module seqdict version 0.0 Module mseqdict version 0.0 ================================================ seqdict - single value dictionary msedict - multiple value dictionary The Python built-in dictionary has no reliable sequence order because of performance reasons. The two new dictionaries introduced here keep their entries in sequence. * seqdict keeps one value for one key * mseqdict keeps multiple values per key and is the closest emulation of areal world dictionary. As the sequential dictionary is a combination of a list and a dictionary you can do most operations defined with lists as well and much more. Now you can slice, add, sort with dictionaries. The functional operations map, filter, reduce are implemented as well. Use a dictionary like a stack with push and pop. Split it, reverse it and swap keys and values. A small tutorial is provided as HTML and Postscript Source and is subject to become improved some other day. I think both dictionaries are candidates for the python standard library. Use the seqdicts to emulate a printed dictionary. Use them for csv-tables. Keep parsed code in a seqdict, modify it and write it back ...

ScientificPython 2.0b1
by Konrad Hinsen 27 Jul '99

27 Jul '99

The first public beta release of ScientificPython 2.0 is now available from http://starship.python.net/crew/hinsen/scientific.html and http://dirac.cnrs-orleans.fr/programs/scientific.html This is a completely revised release and *not* compatible with earlier releases. The major difference is the introduction of a package structure; all modules are now submodules of the top-level module Scientific. Version 2 also includes the netCDF interface module, which was previously in a separate distribution. Another important new feature is full documentation :-) Following established traditions in the Python community, I will be on vacation for three weeks from Wednesday. Please take your time to fix any bugs before reporting them to me ;-) == ------------------------------------------------------------------------------- Konrad Hinsen | E-Mail: hinsen(a)cnrs-orleans.fr Centre de Biophysique Moleculaire (CNRS) | Tel.: +33-2.38.25.55.69 Rue Charles Sadron | Fax: +33-2.38.63.15.17 45071 Orleans Cedex 2 | Deutsch/Esperanto/English/ France | Nederlands/Francais ------------------------------------------------------------------------------- <A HREF="http://starship.skyport.net/crew/hinsen/scientific.html"> ScientificPython 2.0</A> - Konrad Hinsen's collection of scientific/math modules; now includes netCDF module and full documentation.
