by aztech1200＠yahoo.com 10 Jun '04

10 Jun '04

Vasudev Ram has released v1.0 of xtopdf as an open source project on SourceForge. The URL is: http://sourceforge.net/projects/xtopdf xtopdf is a project to provide ways of converting the content of other file formats to PDF. Currently supported formats are: 1. Plain text 2. .DBF (XBase) files. Others will follow over time. The software is written in Python. It requires: 1. Python 2.2 or higher (http://www.python.org/2.2.3) 2. The open source version of the ReportLab toolkit (also written in Python). (http://www.reportlab.org) xtopdf is useful for quickly converting plain text files or the content of .DBF files to PDF format. xtopdf is cross-platform - has no OS-dependent code, so should work on any platform where Python runs, including Linux, UNIX and Windows.

PyTET a Python TET API binding
by Neil Moses 09 Jun '04

09 Jun '04

I would like to announce the release of PyTET a Python TET API binding. PyTET is a Python implementation of the Open Group Test Environment Toolkit (TET) API. The implementation has been done using the interface compiler SWIG (http://www.swig.org). PyTET was developed on a RedHat 9.0 Linux using TETware release 3.7, but there is no reason it shouldn't work on any POSIX conforming platform that supports Python and one of TET 3.3, TET3.6 or TETware 3.7. For more information about the release and obtaining the software read the following article: http://lwn.net/Articles/86545 Regards, Neil Moses. The Open Group.

ZODB 3.3 beta 1 released
by Tim Peters 07 Jun '04

07 Jun '04

I'm pleased to announce the release of ZODB 3.3 beta 1. As always with the first beta release, the feature set for ZODB 3.3 is frozen now. The ZODB 3.3b1 release requires Python 2.3.3. Python 2.3.4 is recommended, and will be required for ZODB 3.3 final. This version of ZODB supports Zope 2 and Zope 3. ZODB 3.3b1 matches the ZODB code included in the ZopeX3-3.0.0b1 release, and contains code that will be released in Zope 2.8. You can download a source tarball or Windows installer from: http://zope.org/Products/ZODB3.3 The changes since ZODB 3.3a3 consist mostly of fixes for longstanding ZODB bugs, several of which were backported to the Zope 2.7 maintenance branch. The news file lists the changes in more detail: http://zope.org/Products/ZODB3.3/NEWS.html Since ZODB 3.3 will be at the heart of database operations in Zope 2.8 and Zope 3, it's important that it be tested as broadly as possible. Please download it and give it a try!

itools 0.4.1 has been released, besides minor fixes, the big news are: - development has moved from CVS to GNU arch (with wonderful results) - the documentation has been released for the first time Download from (new address): http://www.ikaaro.org/ Browse the archive at: http://in-girum.net/cgi-bin/archzoom.cgi What is itools? =============== Itools is a Python package that encapsulates several Python tools: * itools.uri -- an API to manage URIs, to identify and locate resources. * itools.resources -- an abstraction layer over resources that let to manage them with a consistent API, independently of where they are stored. * itools.handlers -- resource handlers infrastructure (resource handlers are non persistent classes that add specific semantics to resources). This package also includes several handlers out of the box. * itools.xml -- XML infrastructure, includes resource handlers for XML, XHTML and HTML documents. Plus the Simple Template Language. * itools.i18n -- tools for language negotiation and text segmentation. * itools.workflow -- represent workflows as automatons, objects can move from one state to another through transitions, classes can add specific semantics to states and transitions. * itools.lucene -- An underway implementation of the famous Jakarta's indexing and search tool. -- J.

pytz - World timezones in Python
by Stuart Bishop 06 Jun '04

06 Jun '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 http://sourceforge.net/projects/pytz/ pytz is a transformation of the public domain Olsen timezone database into pure Python code. This library allows accurate and cross platform timezone calculations using Python 2.3 or higher. This implementation solves the issue of ambiguous times at the end of daylight savings, which you can read more about in the Python Library Reference (datetime.tzinfo). The only remaining inaccuracy is that datetime.strftime only reports the UTC offset to the nearest minute (This is probably a feature - you have to draw a line somewhere). 536 of the Olsen timezones are supported. The missing few are for Riyadh Solar Time in 1987, 1988 and 1989. As Saudi Arabia gave up trying to cope with their timezone definition, I see no reason to complicate my code further to cope with them. (I understand the intention was to set sunset to 0:00 local time, the start of the Islamic day. In the best case caused the DST offset to change daily and worst case caused the DST offset to change each instant depending on how you interpreted the ruling.) Note that if you perform date arithmetic on local times that cross DST boundaries, the results may be in an incorrect timezone (ie. subtract 1 minute from 2002-10-27 1:00 EST and you get 2002-10-27 0:59 EST instead of the correct 2002-10-27 1:59 EDT). This cannot be resolved without modifying the Python datetime implementation. However, these tzinfo classes provide a normalize() method which allows you to correct these values. Installation - ------------ This is a standard Python distutils distribution. To install the package, run the following command as an administrative user:: python setup.py install License - ------- BSD style license. I'm more than happy to relicense this code for inclusion in other open source projects. Example & Usage - --------------- >>> from datetime import datetime, timedelta >>> from pytz import timezone >>> utc = timezone('UTC') >>> eastern = timezone('US/Eastern') >>> utc_dt = datetime(2002, 10, 27, 6, 0, 0, tzinfo=utc) >>> loc_dt = utc_dt.astimezone(eastern) >>> fmt = '%Y-%m-%d %H:%M:%S %Z (%z)' >>> loc_dt.strftime(fmt) '2002-10-27 01:00:00 EST (-0500)' >>> (loc_dt - timedelta(minutes=10)).strftime(fmt) '2002-10-27 00:50:00 EST (-0500)' >>> eastern.normalize(loc_dt - timedelta(minutes=10)).strftime(fmt) '2002-10-27 01:50:00 EDT (-0400)' >>> (loc_dt + timedelta(minutes=10)).strftime(fmt) '2002-10-27 01:10:00 EST (-0500)' Latest Versions - --------------- This module will be updated after releases of the Olsen timezone database. The latest version can be downloaded from sourceforge_. .. _sourceforge: http://sourceforge.net/projects/pytz/ Further Reading - --------------- More info than you want to know about timezones:: http://www.twinsun.com/tz/tz-link.htm Contact - ------- Stuart Bishop <stuart(a)stuartbishop.net> - -- Stuart Bishop <stuart(a)stuartbishop.net> http://www.stuartbishop.net/ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.3 (Darwin) iD8DBQFAwyglAfqZj7rGN0oRAlxQAJ9+8J6lTH+jG9VbR6MHWASGjxgyiQCgmvRU 0xU+l0F3MzAfFor6gWQz9s8= =Cdcp -----END PGP SIGNATURE-----
