by aztech1200＠yahoo.com 16 Jun '04

16 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.

by Brian Quinlan 15 Jun '04

15 Jun '04

What's new? =========== The deadline for talk submission for the Vancouver Python Workshop has been extended until June 22nd. This is mainly due to schedule disruptions caused by the EuroPython conference but also because we are looking for a more diverse group of speakers i.e. not just Python luminaries. So far, we have received many interesting talk submissions, concerning: o Windows programming in Python o MacOS X programming in Python o Python IDE construction o Zope/Plone (custimization, working with DBs, debugging, etc.) o Python's future o Python programming techniques (optimization, constaints, blocks and views, etc.) o Pyrex o Prothon o Pygame o Twisted o Python in business Speakers include: o Guido van Rossum (the creator of Python) o Paul Everitt (co-founder of Zope Corp) o David Ascher (author of "Learning Python" & "The Python Cookbook") o Andy McKay (author of "The Definitive Guide to Plone") o Kevin Altis (wxPython & PythonCard developer) o Paul Prescod (core Python developer - XML libraries) o Trent Mick (core Python developer - logging & 64-bit port) But we would like more typical Python programmers to submit talks as well! To submit a talk, see: http://www.vanpyz.org/conference/registration/submissions.html For general conference information, see: http://www.vanpyz.org/conference The revisted deadline for talk submission is June 22nd. About the Vancouver Python Workshop =================================== The conference will begin on July 31st with keynote addresses by Guido van Rossum (the creator of Python) and Paul Everitt (co-founder of Zope Corp).

RELEASED: pynits 040615
by François Pinard 15 Jun '04

15 Jun '04

Hi, my Python and Vim friends. Here is the initial release of `pynits', and the beginning of its documentation file. I hope some courageous souls will help me at eradicating packaging and other blunt bugs! :-) *pynits.txt* Tidying up Python files TIDYING PYTHON CODE WITHIN VIM François Pinard pinard(a)iro.umontreal.ca Pynits is a tool which I find useful while editing Python source code with Vim, for tidying up individual sources lines, and some auxiliary tasks. It is particularly helpful when formatting lines holding long or complex expressions. This tool requires a Python-enabled Vim. 1. Introduction |pynits-introduction| 2. Finding nits |pynits-finding-nits| 3. Reformatting lines |pynits-reformatting| 4. Other commands |pynits-other-commands| The Pynits tool may be downloaded from: http://fp-etc.progiciels-bpi.ca/showfile.html?mode=archives while installation directives may be found at: http://fp-etc.progiciels-bpi.ca/showfile.html?name=pynits/README This file you are reading is also available on the Web as: http://fp-etc.progiciels-bpi.ca/showfile.html?name=pynits/pynits.txt WARNING: This tool is in alpha state, its specifications may change. Write to the author for corrections, suggestions or bug reports. ============================================================================== 1. Introduction *pynits-introduction* I once had to take over the maintenance of a set of big Python modules, written by someone without much concern about source line length limits, and also a bit lacking in the area of sound coding standards. The sources were hard to read on an usual terminal screen, hard to print without stunts on a printer, hard to edit: in a word, hard to maintain. When it comes to source coding standards, people develop religious feelings. My personal coding practices, which are somehow reflected in this tool, are surely debatable and questionable, yet I dare to think they are quite reasonable. I use an eclectic choice of good ideas from various sources: the Python mode as written for GNU Emacs, the standard Python plugin for Vim, Guido's own style as he documented it, some relevant parts of GNU and Gnits standards, good horse sense, but also, my own programming experience, accumulated for a good while by now. Source code lines are often carefully crafted by programmers, and a reformatting tool may defeat local art work. This is why I think reformatting is best done from with a scalpel, like Vim may be, than operated in bulk or in batch. The programmer may choose to accept or refuse, on a line basis, suggestions made by a tool like this one. There are three sets of commands in this tool. The first set is meant to discover and report various formatting nits. The programmer may then ask the tool for correcting them, when a correction recipe is known. The second set takes a whole Python source line, possibly continued, and fully rebuilds a surface representation from its syntax tree. The third set contains a few random commands for simple tasks.

ANN: PyGUI 1.3 released (Greg's Pythonic GUI Framework)
by greg 14 Jun '04

14 Jun '04

PyGUI (Greg's Pythonic GUI Framework) Version 1.3 ================================================= Some of you may remember the project I started a few years ago to define a pythonic GUI API for implementation on multiple platforms. I didn't make much progress on it for a while, but the project wasn't dead, just resting. Following a recent burst of activity, I am now pleased to announce the release of version 1.3. This release marks a milestone in the development of PyGUI, because, for the first time, implementations for two platforms are included: * MacOS X, via Carbon * Linux, via Gtk The Gtk implementation should also be usable on other Unix/X11 systems, or on Windows, if suitable libraries are installed. Download from here, or read the documentation online: http://www.cosc.canterbury.ac.nz/~greg/python_gui/ Note: This version is not quite complete yet; support for images is missing, and a few classes remain to be documented. I expect to remedy these things soon. Greg Ewing greg(a)cosc.canterbury.ac.nz

ZODB 3.2.2 beta 1 released
by Tim Peters 12 Jun '04

12 Jun '04

I'm pleased to announce the release of ZODB 3.2.2 beta 1. This is a bugfix release for the ZODB 3.2 line, and will be the version of ZODB released with Zope 2.7.1b2. The ZODB 3.2.2b1 release requires Python 2.3.3 or later. The ZODB 3.2 line supports Zope 2 only; Zope 3 requires ZODB 3.3. You can download a source tarball or Windows installer from: http://zope.org/Products/ZODB3.2 The changes since ZODB 3.2.1 consist of bugfixes, to BTrees, parts of ZODB proper, and support tools. See the news file for details: http://zope.org/Products/ZODB3.2/NEWS Important notes about Berkeley-based storages: Support for the experimental Berkeley-based storages has been dropped: they created more problems than the community has been able to fix, and nobody has done work on them for many months. Unfortunately, removing the code for BDBFullStorage and BDBMinimalStorage is also delicate, and it still exists in this release. We recommend not using it; the Berkeley code has already been removed from the ZODB 3.3 line. Note too that if you don't have "the right" version of Sleepycat Berkeley DB installed on your system, ZODB's test suite may fail-- or even segfault --as a result. This isn't an issue on Windows, because Python on Windows includes a suitable Sleepycat release (4.1.25). The problem appears most likely to occur on Linux systems with a bsddb from the later 4.2 line. While there's no resource to work on Berkeley problems, I'll at least try to disable the Berkeley tests for ZODB 3.2.2 final.

New News: === ==== I have updated the version of Python to 2.3.4-1. The tarballs should be available on a Cygwin mirror near you shortly. The following is the only notable change since the previous release: o upgrade to Python 2.3.4 Old News: === ==== Python is an interpreted, interactive, object-oriented programming language. If interested, see the Python web site for more details: http://www.python.org/ Please read the README file: /usr/share/doc/Cygwin/python-2.3.4.README since it covers requirements, installation, known issues, etc. To update your installation, click on the "Install Cygwin now" link on the http://cygwin.com/ web page. This downloads setup.exe to your system. Then, run setup and answer all of the questions. Note that we have recently stopped downloads from sources.redhat.com (aka cygwin.com) due to bandwidth limitations. This means that you will need to find a mirror which has this update. In the US, ftp://mirrors.rcn.net/mirrors/sources.redhat.com/cygwin/ is a reliable high bandwidth connection. In Germany, ftp://ftp.uni-erlangen.de/pub/pc/gnuwin32/cygwin/mirrors/cygnus/ is usually pretty good. In the UK, http://programming.ccp14.ac.uk/ftp-mirror/programming/cygwin/pub/cygwin/ is usually up-to-date within 48 hours. If one of the above doesn't have the latest version of this package then you can either wait for the site to be updated or find another mirror. The setup.exe program will figure out what needs to be updated on your system and will install newer packages automatically. If you have questions or comments, please send them to the Cygwin mailing list at: cygwin(a)cygwin.com . I would appreciate if you would use this mailing list rather than emailing me directly.

SC-Track Roundup 0.7.4 - an issue tracking system
by Richard Jones 11 Jun '04

11 Jun '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Roundup is a simple-to-use and -install issue-tracking system with command-line, web and e-mail interfaces. It is based on the winning design from Ka-Ping Yee in the Software Carpentry "Track" design competition. 0.7.4 is a bug fix release, including: - - re-acquire the OTK manager when we re-open the database - - mailgw handler can close the database on us - - fixed grouping by a NULL Link value - - fixed anydbm import/export (sf bugs 965216, 964457, 964450) - - fix python 2.3.3 strftime deprecation warning (sf patch 968398) - - fix some column datatypes in postgresql and mysql (sf bugs 962611, 959177 and 964231) - - fixed RDBMS journal packing (sf bug 959177) - - fixed filtering by floats in anydbm (sf bug 963584) - - fixed mysql upgrading of journals (sf bug 950410) If you're upgrading from an older version of Roundup you *must* follow the "Software Upgrade" guidelines given in the maintenance documentation. Roundup requires python 2.1.3 or later for correct operation. To give Roundup a try, just download (see below), unpack and run:: python demo.py Source and documentation is available at the website: http://roundup.sourceforge.net/ Release Info (via download page): http://sourceforge.net/projects/roundup Mailing lists - the place to ask questions: http://sourceforge.net/mail/?group_id=31577 About Roundup ============= Roundup manages a number of issues (with flexible properties such as "description", "priority", and so on) and provides the ability to: (a) submit new issues, (b) find and edit existing issues, and (c) discuss issues with other participants. The system will facilitate communication among the participants by managing discussions and notifying interested parties when issues are edited. One of the major design goals for Roundup that it be simple to get going. Roundup is therefore usable "out of the box" with any python 2.1+ installation. It doesn't even need to be "installed" to be operational, though a disutils-based install script is provided. It comes with two issue tracker templates (a classic bug/feature tracker and a minimal skeleton) and seven database back-ends (anydbm, bsddb, bsddb3, sqlite, metakit, mysql and postgresql). -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (GNU/Linux) iD8DBQFAyR3FrGisBEHG6TARAuA7AJ9NQWbNkfKfw/qnSBrjdvCtgvY51ACfZfBy IUbri/6bXheF9XN3gOrwfBQ= =EEkB -----END PGP SIGNATURE-----
