Message-ID: <8188af0b0906021047p77c71631q4c7f617b62c4f90c@mail.gmail.com>
Hi,
Pyowa will be meeting Thursday, June 4th in Ames. We will be meeting
at the Ames
Public Library from 7 to 8:45 p.m. The current plan for the meeting is to
have a code review of sorts on some member submitted GIS-type code. Then we
will have a short presentation on one of the modules from Python's standard
library. Whatever time is left over will be used for socializing and
planning the next meeting. If you have ideas or would like to present
something, please let me know at the meeting or through email.
In other news, you can see my experiments in recording some of our meetings
here: http://pyowa.blip.tv/
Please note that if you don't have a fast internet connection, then you will
be disappointed as it will take eons to buffer. Let me know if you plan to
come to the meeting. Thanks!

Subject: ANN: Numexpr 1.3 released
Message-ID: <200906021937.11693.faltet@pytables.org>
========================
Announcing Numexpr 1.3
========================
Numexpr is a fast numerical expression evaluator for NumPy. With it,
expressions that operate on arrays (like "3*a+4*b") are accelerated
and use less memory than doing the same calculation in Python.
On this release, and due to popular demand, support for single
precision floating point types has been added. This allows for both
improved performance and optimal usage of memory for the
single precision computations. Of course, support for single
precision in combination with Intel's VML is there too :)
However, caveat emptor: the casting rules for floating point types
slightly differs from those of NumPy. See the ``Casting rules``
section at:
http://code.google.com/p/numexpr/wiki/Overview
or the README.txt file for more info on this issue.
In case you want to know more in detail what has changed in this
version, see:
http://code.google.com/p/numexpr/wiki/ReleaseNotes
or have a look at RELEASE_NOTES.txt in the tarball.
Where I can find Numexpr?
=========================
The project is hosted at Google code in:
http://code.google.com/p/numexpr/
And you can get the packages from PyPI as well:
http://pypi.python.org/pypi
How it works?
=============
See:
http://code.google.com/p/numexpr/wiki/Overview
for a detailed description by the original author (David M. Cooke).
Share your experience
=====================
Let us know of any bugs, suggestions, gripes, kudos, etc. you may
have.
Enjoy!

Veusz 1.4
---------
Velvet Ember Under Sky Zenith
-----------------------------
http://home.gna.org/veusz/
Veusz is Copyright (C) 2003-2009 Jeremy Sanders
Licenced under the GPL (version 2 or greater).
Veusz is a Qt4 based scientific plotting package. It is written in
Python, using PyQt4 for display and user-interfaces, and numpy for
handling the numeric data. Veusz is designed to produce
publication-ready Postscript/PDF output. The user interface aims to be
simple, consistent and powerful.
Veusz provides a GUI, command line, embedding and scripting interface
(based on Python) to its plotting facilities. It also allows for
manipulation and editing of datasets.
Changes in 1.4:
* Dates can be plotted on axes
* Bar graph component, support bars in groups and stacked bars
with error bars
* Improved import
- text lines can be ignored in imported files
- prefix and suffix can be added to dataset names
- more robust import dialog
* Markers can be "thinned" for large datasets
* Further LaTeX support, including \frac for fractions and \\
for line breaks.
* Keys show error bars on datasets with errors
* Axes can scale plotted data by a factor
More minor changes
* Mathematical expressions can be entered in many places where
numbers are entered (e.g. axis minima)
* Many more latex symbols
* Text labels can also be placed outside graphs directly on pages
* Dataset expressions can be edited
* Data can be copied out of data edit dialog. Rows can be inserted or
deleted.
* Mac format line terminators are allowed in import files
* Preview window resizes properly in import dialog
Features of package:
* X-Y plots (with errorbars)
* Line and function plots
* Contour plots
* Images (with colour mappings and colorbars)
* Stepped plots (for histograms)
* Bar graphs
* Plotting dates
* Fitting functions to data
* Stacked plots and arrays of plots
* Plot keys
* Plot labels
* Shapes and arrows on plots
* LaTeX-like formatting for text
* EPS/PDF/PNG/SVG export
* Scripting interface
* Dataset creation/manipulation
* Embed Veusz within other programs
* Text, CSV and FITS importing
Requirements:
Python (2.4 or greater required)
http://www.python.org/
Qt >= 4.3 (free edition)
http://www.trolltech.com/products/qt/
PyQt >= 4.3 (SIP is required to be installed first)
http://www.riverbankcomputing.co.uk/pyqt/
http://www.riverbankcomputing.co.uk/sip/
numpy >= 1.0
http://numpy.scipy.org/
Optional:
Microsoft Core Fonts (recommended for nice output)
http://corefonts.sourceforge.net/
PyFITS >= 1.1 (optional for FITS import)
http://www.stsci.edu/resources/software_hardware/pyfits
For documentation on using Veusz, see the "Documents" directory. The
manual is in pdf, html and text format (generated from docbook).
Issues with the current version:
* Due to Qt, hatched regions sometimes look rather poor when exported
to PostScript or PDF.
* Due to a bug in Qt, some long lines, or using log scales, can lead
to very slow plot times under X11. This problem is seen with
dashed/dotted lines. It is fixed by upgrading to Qt-4.5.1 (the
Veusz binary version includes this Qt version).
* Can be very slow to plot large datasets if antialiasing is enabled.
Right click on graph and disable antialias to speed up output. This
is mostly a problem with older Qt versions, however.
If you enjoy using Veusz, I would love to hear from you. Please join
the mailing lists at
https://gna.org/mail/?group=veusz
to discuss new features or if you'd like to contribute code. The
latest code can always be found in the SVN repository.

Subject: ANN: HDF5 for Python (h5py) 1.2 *BETA*
Message-ID:
============================================
Announcing HDF5 for Python (h5py) 1.2 *BETA*
============================================
I'm pleased to announce the availability of HDF5 for Python 1.2 beta! This
release represents a significant update to the h5py feature set. Bug
reports, questions and complaints are welcome and needed!
Downloads, bug tracker: http://h5py.googlecode.com
Documentation: h5py.alfven.org
Contact email: h5py at alfven dot org
What is h5py?
-------------
HDF5 for Python (h5py) is a general-purpose Python interface to the
Hierarchical Data Format library, version 5. HDF5 is a versatile,
mature scientific software library designed for the fast, flexible
storage of enormous amounts of data.
>From a Python programmer's perspective, HDF5 provides a robust way to
store data, organized by name in a tree-like fashion. You can create
datasets (arrays on disk) hundreds of gigabytes in size, and perform
random-access I/O on desired sections. Datasets are organized in a
filesystem-like hierarchy using containers called "groups", and
accesed using the tradional POSIX /path/to/resource syntax.
In addition to providing interoperability with existing HDF5 datasets
and platforms, h5py is a convienient way to store and retrieve
arbitrary NumPy data and metadata.
What's new in 1.2
-----------------
- Variable-length strings are now supported! They are mapped to native
Python strings via the NumPy "object" type. VL strings may be read,
written and created from h5py, and are allowed in all HDF5 contexts,
even as members of compound or array types.
- Enumerated types are now fully supported; they can be used in NumPy
anywhere integer types are allowed, and are stored as native HDF5
enums. Conversion between integers and enums is supported.
- The NumPy "array" dtype is now allowed as a top-level type when
creating a dataset, not just as a member of a compound type.
- Many different low-level HDF5 drivers can now be used when creating
a file, which allows purely in-memory ("core") files, multi-volume
("family") files, and files which use low-level buffered I/O.
- HDF5 exceptions now inherit from common Python built-ins like TypeError
and ValueError (in addition to the current HDF5 error hierarchy), freeing
the user from knowledge of the HDF5 error system.
- Unicode file names are now supported
- Groups and attributes now support the standard Python dictionary
interface methods, including keys(), values() and friends.
Design revisions since 1.1
--------------------------
- The role of the "name" attribute on File objects has changed. "name"
now returns the HDF5 path of the File object ('/'); the file name on
disk is available at File.filename.
- Dictionary-interface methods for Group and AttributeManager objects have
been renamed to follow the standard Python convention (keys(), values(),
etc). The old method names are still available but deprecated. They
will not be removed until h5py 1.4 or equivalent.
- The HDF5 shuffle filter is no longer automatically activated when
GZIP or LZF compression is used; many datasets "in the wild" do not
benefit from shuffling.
Standard features
-----------------
- Supports storage of NumPy data of the following types:
* Integer/Unsigned Integer
* Float/Double
* Complex/Double Complex
* Compound ("recarray")
* Strings
* Boolean
* Array
* Enumeration (integers)
* Void
- Random access to datasets using the standard NumPy slicing syntax,
including a subset of fancy indexing and point-based selection
- Transparent compression of datasets using GZIP, LZF or SZIP,
and error-detection using Fletcher32
- "Pythonic" interface supporting dictionary and NumPy-array metaphors
for the high-level HDF5 abstrations like groups and datasets
- A comprehensive, object-oriented wrapping of the HDF5 low-level C API
via Cython, in addition to the NumPy-like high-level interface.
- Supports many new features of HDF5 1.8, including recursive iteration
over entire files and in-library copy operations on the file tree
- Thread-safe
Where to get it
---------------
* Main website, documentation: http://h5py.alfven.org
* Downloads, bug tracker: http://h5py.googlecode.com
Requires
--------
* Linux, Mac OS-X or Windows
* Python 2.5 (Windows), Python 2.5 or 2.6 (Linux/Mac OS-X)
* NumPy 1.0.3 or later
* HDF5 1.6.5 or later (including 1.8); HDF5 is included with
the Windows version.
Thanks
------
Thanks to D. Dale, E. Lawrence and other for their continued support
and comments. Also thanks to the Francesc Alted and the PyTables project,
for inspiration and generously providing their code to the community. Thanks
to everyone at the HDF Group for creating such a useful piece of software.

Subject: Treat C FILE* as C++ streams
Message-ID:
Hello to everyone.
I'm an Italian engineer and I'm approaching to Python, particularly to
Python extension through C++ (because I'm an experienced C++ programmer).
I've seen that Python files are basically managed through the C FILE pointer.
I've recently released on Google Code a very small library which allows to
treat the C FILE* as a C++ stream and I think this should be useful to
Python developers.
The link is this: http://code.google.com/p/mds-utils/
The library uses Boost.Iostreams.
Think to this situation: you have some C++ classes or functions that
take a C++ stream or
fstream as parameter. You want to make a Python extension from this
library but you want
to pass a Python file object to your C++ code. Using my library, you
can wrap the underlying
FILE* into an object that behaves like a C++ stream.
I've not yet built an on-line documentation, but the library comes
with detailed doxygen documentation and useful examples.
I hope my library will be useful to the Python community and I'd like
to see a link to it on the
Python web site.
Best regards to all of you.
Michele

Subject: Announcing jsonlib2 1.5 - the simplejson release
Message-ID:
I've just revved jsonlib2, the C-based json parser used at metaweb for
freebase.com. Compared with simplejson, my initial tests have it
between 21 and 25 times faster for loads() and around 10x faster for
dumps()
http://code.google.com/p/jsonlib2/
For those of you who have never used jsonlib/jsonlib2, all you have to
know is that with this version, jsonlib2 is much more compatible with
simplejson/json. Got a ways to go but for most applications it should
be a drop-in replacement.
This is the first C Python extension I've ever written, and I actually
inherited most of the code when I forked jsonlib because of
differences with the author. This means I'm very interested in patches/
critiques/etc.
For those using jsonlib or jsonlib2:
Version 1.5 is a big API change - loads() and dumps() are now almost
completely compatible with simplejson's loads() and dumps() - so it
really should be a drop-in replacement. Here are a few things that
have been possible with simplejson, but not with jsonlib2:
1) looser enforcement of json spec - allowing stuff like:
>>> jsonlib2.dumps({None: "foo"})
'{"null": "foo"}'
>>> jsonlib2.dumps(None)
'null'
2) full support for Infinity, NaN, in both dumping AND parsing, by
default:
>>> jsonlib2.dumps(1e10000)
'Infinity'
>>> jsonlib2.loads(jsonlib2.dumps(1e10000))
inf
I've actually imported the simplejson unit tests, and this library
passes 26 of 32 tests, and most failures are just due to the fact that
jsonlib2 prefers to output in utf8 rather than unicode, for faster
output from a web server.

It uses GStreamer [1] for media playback and pigment [2] to create an
appealing and intuitive user interface.
This release is a lightweight release, meaning it is pushed through our
automatic plugin update system. Additionally a windows installer is
available for download on our website.
As usual, for users already running Moovida, the upgrade to 1.0.2 should
be done automatically via the plugin repository.
A complete list of the issues fixed can be found at:
http://launchpad.net/elisa/+milestone/1.0.2
This is also summarised in the (attached) release notes.
Installers and sources can be downloaded from

Subject: python-colormath 1.0.1 Released
Message-ID: <8de369d70906050643t184af1bdob0779a19d4bcd7b1@mail.gmail.com>
Greetings,
After much testing and refinement in an industrial setting, python-colormath
has been released to the public under the GPLv3.
What is python-colormath?
====================
python-colormath is a developer-oriented module that abstracts a number of
color math operations behind a small set of classes representing color
spaces (IE: RGB, CIE Lab, XYZ, and LCH, etc.). Color conversions, delta E
comparisons, and density calculations are all relatively involved, but are
hid behind the simple API. For example, conversions from RGB to CMY and CMYK
are trivial, while conversions from Spectral to LCHab are equally so (even
though much more math happens behind the scenes).
Quantitative comparisons of the difference between two colors may be
calculated using one of several delta E formulas. Colors are automatically
converted to the appropriate comparison color space and the delta E formula
returns the result with no real effort on your part.
For those working with spectral power distributions, the module can convert
them to color spaces or ANSI/ISO density values. This is particularly useful
when trying to minimize the difference in the readings of two different
spectrophotometric devices.
It is perhaps best to consider python-colormath as a more advanced, complete
version of Python's own colorsys module. The number of supported color
spaces, operations, and capabilities far exceeds colorsys (which is simple
and minimalistic by design).
Avoid color calculation errors
=====================
One of the biggest benefits of this module is that it was designed and
implemented by members of the Graphic Communications and print industries.
The developers having a formal background in color science leaves you with a
very complete, "correct" implementation of color math. Unlike the other
color libraries, python-colormath avoids many of the problems with varying
types of RGB, color illuminants and observer angles, and many different
things that go on behind the scenes.
python-colormath is also rigorously tested through its use in a previously
commercial color management system. Additionally, all conversions are unit
tested and monitored for deviations wich each change to the codebase. This
ensures consistent, repeatable results through each release.

Subject: python-graph-1.6.0 released
Message-ID: <1244294230.3337.28.camel@localhost.localdomain>
python-graph
release 1.6.0
http://code.google.com/p/python-graph/
------------------------------------------------------------------------
python-graph is a library for working with graphs in Python.
This software provides ?a suitable data structure for representing
graphs and a whole set of important algorithms.
The code is appropriately documented and API reference is generated
automatically by epydoc.
Provided features and algorithms:
* Support for directed, undirected, weighted and non-weighted graphs
* Support for hypergraphs
* Canonical operations
* XML import and export
* DOT-Language output (for usage with Graphviz)
* Random graph generation
* Accessibility (transitive closure)
* Breadth-first search
* Critical path algorithm
* Cut-vertex and cut-edge identification
* Depth-first search
* Heuristic search (A* algorithm)
* Identification of connected components
* Minimum spanning tree (Prim's algorithm)
* Mutual-accessibility (strongly connected components)
* Shortest path search (Dijkstra's algorithm)
* Topological sorting
* Transitive edge identification
The 1.6.x series is our refactoring series. Along the next releases,
we'll change the API so we can better prepare the codebase to new
features. If you want a softer, directed transition, upgrade your code
to every release in the 1.6.x series. On the other hand, if you'd
rather fix everything at once, you can wait for 1.7.0.
Download: http://code.google.com/p/python-graph/downloads/list
(tar.bz2, zip and egg packages are available.)
Installing:
If you have easy_install on your system, you can simply run:

Subject: progress.py 1.0.0 - Track and display progress, providing estimated
completion time.
Message-ID:
I couldn't find any module that would just let me add progress to all the
random little scripts I write. So I wrote one. You can download and read
about it at http://www.casualhacker.net/blog/progress_py/
Below is the module's description. I welcome any comments and suggestions.
Tim
DESCRIPTION
This module provides 2 classes to simply add progress display to any
application. Programs with more complex GUIs might still want to use it
for the
estimates of time remaining it provides.
Use the ProgressDisplay class if your work is done in a simple loop:
from progress import *
for i in ProgressDisplay(range(500)):
do_work()
If do_work() doesn't send any output to stdout you can use the
following,
which will cause a single status line to be printed and updated:
from progress import *
for i in ProgressDisplay(range(500), display=SINGLE_LINE):
do_work()
For more complex applications, you will probably need to manage a
Progress
object yourself:
from progress import *
progress = Progress(task_size)
for part in task:
do_work()
progress.increment()
progress.print_status_line()
If you have a more sophisticated GUI going on, you can still use
Progress
objects to give you a good estimate of time remaining:
from progress import *
progress = Progress(task_size)
for part in task:
do_work()
progress.increment()
update_gui(progress.percentage(), progress.time_remaining())

pypi-grep is just a file with one long line per PyPI package,

Why ? Grepping a local file is very fast and very simple, for old

"what's XYZ ?"
hg clone http://bitbucket.org/denisb/pypi-grep/
should get pypi-grep and pypi-grepfile-2009-06-08 or the like;
move them to a directory in your PATH.
Notes:
* the pypi-grepfile has only one version per package, the newest;
multiline summaries are folded to one long line
* pypi-grep -h lists the few options
* the data comes from http://pypi.python.org/pypi xmlrpc,
but beware: some packages in list_packages have no

(timeout_xmlrpclib);

Message-ID: <8de369d70906090837u75bfd954n67abbf0c567f175e@mail.gmail.com>
Greetings,
python-colormath 1.0.2 has been released, which addresses an issue with
chromatic adaptations.
What is python-colormath?
====================
python-colormath is a developer-oriented module that abstracts a number of
color math operations behind a small set of classes representing color
spaces (IE: RGB, CIE Lab, XYZ, and LCH, etc.). Color conversions, delta E
comparisons, and density calculations are all relatively involved, but are
hid behind the simple API. For example, conversions from RGB to CMY and CMYK
are trivial, while conversions from Spectral to LCHab are equally so (even
though much more math happens behind the scenes).
What's new in 1.0.2?
===============
* Conversions between all known illuminants is now possible with several
different chromatic adaptation transforms (Von Kries, Bradford, and XYZ
Scaling). Previously this was only possible for some well-known CIE
illuminants.
* Chromatic adaptations may be _slightly_ more accurate (we're talking
miniscule) on certain hardware.

Announcing the inaugural meeting of the newly formed Grand Rapids Python
Users Group (http://www.grpug.org ) in Grand Rapids, MI, USA.
What: *First Meeting of the GRPUG*
When: *Monday, 6/15/09, 6PM - ??*
Where: *Grand Rapids Brewing Company* (
http://www.michiganmenu.com/grbrewing.html )
A few of us checked out the Grand Rapids Brewing Company as a potential
meeting site for the GRPUG, and it looked pretty good. It's a nice
microbrewery and restaurant. My only worry is the ambient noise level, but
my contact there assures me that lowering the canvas shades and doors shuts
out a lot of the sound. Anyways, let's have our first meeting there and see
how it goes. They have appetizers, meals, pop, and - most importantly -
beer! So feel free to have dinner and drink while you're there. The room is
in the back of the main dining hall.
I would like to do a Python IDE/editor roundup, so it would be great if you
could bring a laptop/netbook and show off your favorite IDE or editor. You
don't need to prepare anything elaborate; just fire it up and show off a few
features. In fact, no slides allowed the first night! I think we'll have a
projector available, otherwise we'll huddle around laptops for the demos.
Afterwords we'll socialize and talk about what we envision for GRPUG and how
much we hate all of those inferior programming languages.

ANNOUNCING
eGenix.com pyOpenSSL Distribution
Version 0.9.0-0.9.8k
An easy to install and use repackaged distribution
of the pyOpenSSL Python interface for OpenSSL -
available on Windows, Mac OS X and Unix platforms
This announcement is also available on our web-site for online reading:
http://www.egenix.com/company/news/eGenix-pyOpenSSL-Distribution-0.9.0-0.9.8k-1-GA.html
________________________________________________________________________
INTRODUCTION
The eGenix.com pyOpenSSL Distribution includes everything you need to
get started with SSL in Python. It comes with an easy to use installer
that includes the most recent OpenSSL library versions in pre-compiled
form.
pyOpenSSL is an open-source Python add-on (http://pyopenssl.sf.net/)
that allows writing SSL aware networking applications as well as
certificate management tools.
OpenSSL is an open-source implementation of the SSL protocol
(http://www.openssl.org/).
For more information, please see the product page:
http://www.egenix.com/products/python/pyOpenSSL/
________________________________________________________________________
NEWS
This new release of the eGenix.com pyOpenSSL Distribution updates the
included pyOpenSSL version to 0.9, which includes a new fix for a
serious problem in pyOpenSSL 0.8 related to threaded applications. It
also comes with an important bug-fix update of OpenSSL, now at version
0.9.8k.
The problem causes invalid thread states in the Python interpreter
which then result in random core dumps and seg faults when using
pyOpenSSL 0.8.0 with multi-threaded applications.
The new fix is slightly different than the one we included in 0.8.1
and based on a code analysis we did together with Jean-Paul Calderone
to track down the cause of the problem.
Binaries are available for Linux x86 and x64 as well as Windows x86
and Mac OS X PPC/Intel. They include both pyOpenSSL and the necessary
OpenSSL libraries.
For Plone users and friends of buildout scripts, we have added
pre-built binaries for Windows. They install just like the Linux
versions and allow easy integration of the archives into buildout
scripts.
For our Mac OS X users, we have included new pre-built binaries for
Mac OS X PPC and Intel platforms.

Subject: Python svn builds
Message-ID: <200906120947.19318.a.cavallo@mailsnare.com>
Python svn builds (http://pyvm.sourceforge.net) is a project to provide
python binary builds ready to use.
The main features for these builds are:
+ install under /opt/opt-python-svnXXXXX-2.7a0 (XXXXX is the svn revision)
+ multiple interpreters can be installed side by side
+ installed in parallel to the system python (administrator friendly)
+ they're build for several different platforms (rpm based)
+ the build host is provided by the OpenSUSE buildserver
+ the builds can be deployed using yum/yast/urpmi (OpenSUSE buildserver)
+ each build runs a small smoke test and it is unattented
+ the test results are reported
The aim is:
+ implementing a continuous integration practice
+ to provide python developer with reliable and repeatable builds
+ modules developer can test their modules against the latest python
News for this version:
Few modules (imaging, numpy, pexpect and setuptools) have been added and
they're build for each intepreter.
These are still in testing but the aim here is to have a full complete build
chain with a test suite (next step is providing a test driven development).

Subject: [RELEASED] Python 3.1 Release Candidate 2
Message-ID: <1afaf6160906130746v2d951486v7a52d7b838070189@mail.gmail.com>
On behalf of the Python development team, I'm happy to announce the second
release candidate of Python 3.1.
Python 3.1 focuses on the stabilization and optimization of the features and
changes that Python 3.0 introduced. For example, the new I/O system has been
rewritten in C for speed. File system APIs that use unicode strings now handle
paths with undecodable bytes in them. Other features include an ordered
dictionary implementation, a condensed syntax for nested with statements, and
support for ttk Tile in Tkinter. For a more extensive list of changes in 3.1,
see http://doc.python.org/dev/py3k/whatsnew/3.1.html or Misc/NEWS in the Python
distribution.
This is a release candidate, and as such, we do not recommend use in production
environments. However, please take this opportunity to test the release with
your libraries or applications. This will hopefully discover bugs before the
final release and allow you to determine how changes in 3.1 might impact you.
If you find things broken or incorrect, please submit a bug report at
http://bugs.python.org
For more information and downloadable distributions, see the Python 3.1 website:

Subject: Join us for the 2nd Scientific Computing with Python Webinar
Message-ID: <9806A7FA-C9F7-4491-8AE1-514DC13851F8@enthought.com>
Hello all Python users:
I am pleased to announce the second installment of a free Webinar
series that discusses using Python for scientific computing.
Enthought hosts this free series which takes place once a month for
about 60-90 minutes. The schedule and length may change based on
participation feedback, but for now it is scheduled for the third
Friday of every month. This free webinar should not be confused
with the EPD webinar on the first Friday of each month which is open
only to subscribers to the Enthought Python Distribution at the Basic
level or above.
This session's speakers will be me (Travis Oliphant) and Peter Wang.
I will show off a bit of EPDLab which is an interactive Python
environment built using IPython, Traits, and Envisage. Peter Wang
will present a demo of Chaco and provide some examples of interactive
visualizations that can be easily constructed using it's classes. If
there is time after the Chaco demo, I will continue the discussion
about Mayavi, but I suspect this will have to wait until the next
session. All of the tools we will show are open-source, freely-
available tools from multiple sources. They can all be conveniently
installed using the Enthought Python Distribution.
This event will take place on Friday, June 19th at 1:00pm CDT and will
last 60 to 90 minutes depending on the questions asked. If you would
like to participate, please register by clicking on the link below or
going to https://www1.gotomeeting.com/register/303689873.
There will be a 15 minute technical help-session prior to the on-line
meeting which you should plan to use if you have never participated in
a GoToWebinar previously. During this time you can test your
connection and audio equipment as well as familiarize yourself with
the GoTo Meeting software (which currently only works with Mac and
Windows systems).
I am looking forward to interacting with many of you again this Friday.
Best regards,
Travis Oliphant

Subject: Moovida Media Center 1.0.3 Release
Message-ID: <4A3787EC.1030806@fluendo.com>
Dear Python users,
The Moovida team is happy to announce the release of Moovida Media
Center 1.0.3, code-named "Lun?tico".
Moovida, formerly known as Elisa, is a cross-platform and open-source
Media Center written in Python.
It uses GStreamer [1] for media playback and pigment [2] to create an
appealing and intuitive user interface.
This release is a lightweight release, meaning it is pushed through our
automatic plugin update system. Additionally a windows installer is
available for download on our website.
As usual, for users already running Moovida, the upgrade to 1.0.3 should
be done automatically via the plugin repository.
Important features of this release include a much faster media scanning
and thumbnailing for videos and pictures, a better handling of plural
forms in translations and updated French translations.
A complete list of the issues fixed can be found at:
http://launchpad.net/elisa/+milestone/1.0.3
This is also summarised in the (attached) release notes.
Installers and sources can be downloaded from
http://www.moovida.com/download/
Bug reports and feature requests are welcome at
http://bugs.launchpad.net/elisa/+filebug
Have a media-centered week,
Olivier, for the Moovida team

Subject: PyQt v4.5.1 Released (Python bindings for Qt)
Message-ID:
PyQt v4.5.1 has been released and is available from
http://www.riverbankcomputing.com/software/pyqt/.
PyQt is a comprehensive set of bindings for the Qt application and UI
framework from Nokia. It supports the same platforms as Qt (Windows,
Linux and MacOS/X).
The highlights of this release include:
- support for Python v3
- support for Qt v4.5
- a new Pythonic API for connecting signals and slots that doesn't
require any knowledge of C++ data types
- support for the GTK+ theme engine.
Windows installers are provided for the GPL version of PyQt which contains
everything needed for PyQt development (including Qt, Qt Designer and
QScintilla) except Python itself.
PyQt v4 is implemented as a set of 18 extension modules containing over
400 classes and over 6,000 functions and methods.
QtCore
The non-GUI infrastructure including event loops, threads, i18n,
Unicode, signals and slots, user and application settings, mapped
files and shared memory.
QtDesigner
A set of classes that allow the Qt Designer GUI design tool to be
extended with PyQt.
QtGui
A rich collection of GUI widgets.
QtHelp
A set of classes for creating and viewing searchable documentation and
being able to integrate online help with PyQt applications. It
includes the C++ port of the Lucene text search engine.
QtNetwork
A set of classes to support TCP and UDP socket programming and higher
level protocols (eg. HTTP, SSL).
QtOpenGL
A set of classes that allows PyOpenGL to render onto Qt widgets.
QtScript
A set of classes that implements a JavaScript interpreter. Python
objects may be exposed in the interpreter as JavaScript objects.
QtScriptTools
A debugger for the JavaScript interpreter.
QtSql
A set of classes that implement SQL data models and interfaces to
industry standard databases. The Windows installers include support
for SQLite, MySQL, PostgreSQL and ODBC.
QtSvg
A set of classes to render SVG files onto Qt widgets.
QtTest
A set of classes to automate unit testing of PyQt applications and
GUIs.
QtWebKit
This implements a web browser engine based on the WebKit engine used by
Apple's Safari browser. It allows the methods and properties of Python
objects to be published and appear as JavaScript objects to scripts
embedded in HTML pages.
QtXML
A set of classes that implement DOM and SAX parsers.
QtXMLPatterns
A set of classes that implement XQuery and XPath support for XML and
custom data models.
QtAssistant
A set of classes that enables the Qt Assistant online help browser to
be integrated with an application.
QAxContainer
A set of classes for Windows that allows the integration of ActiveX
controls and COM objects.
phonon
A cross-platform multimedia framework that enables the use of audio and
video content in PyQt applications. DirectX is used as the Windows
backend, QuickTime as the MacOS/X backend, and GStreamer as the Linux
backend.
DBus
PyQt includes dbus.mainloop.qt that allows the Qt event loop to be used
with the standard DBus Python bindings.
PyQt includes the pyuic4 utility which generates Python code to implement
user interfaces created with Qt Designer in the same way that the uic
utility generates C++ code. It is also able to load Designer XML files
dynamically.
PyQt is available under the GPL and a commercial license. Unlike Qt, PyQt
is not available under the LGPL. The commercial PyQt license allows GPL
applications to be relicensed at any time.

version of CPython. This release has had a strong focus on CPython
compatibility, and so this release of Jython can run more pure Python
apps then any previous release. Please see the NEWS file for detailed
release notes.
I want to thank all of the amazing people who have contributed in
large and small ways to this important Jython release. For the first
time in a long time we have Jython that is a modern version of Python.

Subject: [ANN] first full alpha release of PyLab_Works v0.3
Message-ID: <4A37E400.4080305@gmail.com>
hello,
I am pleased to announce the first full alpha release of PyLab_Works, v0.3.
PyLab_Works is a modular Visual Development Environment, based on
data-flow programming technics. PyLab_Works is specially aimed at
Education, Engineering and Science. The ideas behind PyLab_Works are,
that the final user should not be burdened with programming details and
domain details, whereas the domain expert should be able to implement
the specific domain knowledge without being a full educated programmer.
You can always find my notes on PyLab_Works on
http://pic.flappie.nl
Most of these pages are also collected in a single pdf document, which
can be found here:
http://pylab-works.googlecode.com/files/pw_manual.pdf
The source code and a one-button-Windows-Installer can be found on
codegoogle:
http://code.google.com/p/pylab-works/
The files are rather large, because they contain some data samples.
The Windows-Installer contains everything you need to get started with
PyLab_Works: ConfigObj, gprof2dot, HTTPlib, MatPlotLib, Numpy, Pickle,
Psyco, pyclbr, PyGame, PyLab_Works, PyODBC, Python, RLCompleter, Scipy,
Sendkeys, SQLite3, SQLObject, URLparse, wave, Visual, win32*, wxPython.
Although the PyLab_Works programs are compiled with Py2Exe, all the
source files are explicitly included.

Subject: cx_Logging 2.0
Message-ID: <703ae56b0906172159o2d58e474i255f6aebc5980606@mail.gmail.com>
What is cx_Logging?
cx_Logging is a Python extension module which operates in a fashion
similar to the logging module that ships with Python 2.3 and higher.
It also has a C interface which allows applications to perform logging
independently of or in tandem with Python.
Where do I get it?
http://cx-logging.sourceforge.net
What's new?
1) Added support for Python 3.x.
2) Added support for logging Unicode strings in Python 2.x.
3) Added support for setting the encoding to use for Unicode strings
when starting logging and a Python method SetEncoding() for setting it
afterwards and a Python method GetEncoding() to view the value
currently
being used.
4) Added C methods StartLoggingEx(), StartLoggingStderrEx(),
StartLoggingStdoutEx(), StartLoggingExW() and
StartLoggingForPythonThreadEx() which provide exception information to
the caller and (if applicable) allow the specification of whether
files are reused and rotated (see documentation for more information).
5) Added Python method SetExceptionInfo() which allows specification
of the base exception class, a method for creating an instance of that
class and a message that will be displayed prior to the logging of
exceptions of that class.
6) The Python method LogException() now returns a configured exception
if one was built or passed in directly.
7) Transformed documentation to new style used in Python 2.6 and
higher and enhanced the contents.
8) Added support for compiling on 64-bit Windows.

Subject: bzr 1.16 released!
Message-ID:
Bazaar 1.16, codename "It's yesterday in California" is released!
This version of Bazaar contains the beta release of the new ``2a``
repository format, suitable for testing by fearless, advanced users.
This format or an updated version of it will become the default format
in Bazaar 2.0. Please read the NEWS entry before even thinking about
upgrading to the new format.
Also included are speedups for many operations on huge projects, a bug
fix for pushing stacked new stacked branches to smart servers and the
usual bevy of bug fixes and improvements.
The Bazaar team is happy to announce availability of a new release of
the bzr adaptive version control system. Bazaar is part of the GNU
system .
Thanks to everyone who contributed patches, suggestions, and feedback.
Bazaar is now available for download from
http://bazaar-vcs.org/Download as a source tarball; packages for
various systems will be available soon.
Changes from 1.16rc1 to 1.16final
*********************************
* Fix the nested tree flag check so that upgrade from development formats to
2a can work correctly.
(Jelmer Vernooij, #388727)
* Automatic format upgrades triggered by default stacking policies on a
1.16rc1 (or later) smart server work again.
(Andrew Bennetts, #388675)
Compatibility Breaks
********************
* Display prompt on stderr (instead of stdout) when querying users so
that the output of commands can be safely redirected.
(Vincent Ladeuil, #376582)
New Features
************
* A new repository format ``2a`` has been added. This is a beta release
of the the brisbane-core (aka group-compress) project. This format now
suitable for wider testing by advanced users willing to deal with some
bugs. We would appreciate test reports, either positive or negative.
Format 2a is substantially smaller and faster for many operations on
many trees. This format or an updated version will become the default
in bzr 2.0.
This is a rich-root format, so this repository format can be used with
bzr-svn. Bazaar branches in previous non-rich-root formats can be
converted (including by merge, push and pull) to format 2a, but not vice
versa. We recommend upgrading previous development formats to 2a.
Upgrading to this format can take considerable time because it expands
and more concisely repacks the full history.
If you use stacked branches, you must upgrade the stacked branches
before the stacked-on branches. (See
)
* ``--development7-rich-root`` is a new dev format, similar to ``--dev6``
but using a Revision serializer using bencode rather than XML.
(Jelmer Vernooij, John Arbash Meinel)
* mail_client=claws now supports --body (and message body hooks). Also uses
configured from address. (Barry Warsaw)
Improvements
************
* ``--development6-rich-root`` can now stack. (Modulo some smart-server
bugs with stacking and non default formats.)
(John Arbash Meinel, #373455)
* ``--development6-rich-root`` delays generating a delta index for the
first object inserted into a group. This has a beneficial impact on
``bzr commit`` since each committed texts goes to its own group. For
committing a 90MB file, it drops peak memory by about 200MB, and speeds
up commit from 7s => 4s. (John Arbash Meinel)
* Numerous operations are now faster for huge projects, i.e. those
with a large number of files and/or a large number of revisions,
particularly when the latest development format is used. These
operations (and improvements on OpenOffice.org) include:
* branch in a shared repository (2X faster)
* branch --no-tree (100X faster)
* diff (2X faster)
* tags (70X faster)
(Ian Clatworthy)
* Pyrex version of ``bencode`` support. This provides optimized support
for both encoding and decoding, and is now found at ``bzrlib.bencode``.
``bzrlib.utils.bencode`` is now deprecated.
(Alexander Belchenko, Jelmer Vernooij, John Arbash Meinel)
Bug Fixes
*********
* Bazaar can now pass attachment files to the mutt email client.
(Edwin Grubbs, #384158)
* Better message in ``bzr add`` output suggesting using ``bzr ignored`` to
see which files can also be added. (Jason Spashett, #76616)
* ``bzr pull -r 123`` from a stacked branch on a smart server no longer fails.
Also, the ``Branch.revision_history()`` API now works in the same
situation. (Andrew Bennetts, #380314)
* ``bzr serve`` on Windows no longer displays a traceback simply because a
TCP client disconnected. (Andrew Bennetts)
* Clarify the rules for locking and fallback repositories. Fix bugs in how
``RemoteRepository`` was handling fallbacks along with the
``_real_repository``. (Andrew Bennetts, John Arbash Meinel, #375496)
* Fix a small bug with fetching revisions w/ ghosts into a new stacked
branch. Not often triggered, because it required ghosts to be part of
the fetched revisions, not in the stacked-on ancestry.
(John Arbash Meinel)
* Fix status and commit to work with content filtered trees, addressing
numerous bad bugs with line-ending support. (Ian Clatworthy, #362030)
* Fix problem of "directory not empty" when contending for a lock over
sftp. (Martin Pool, #340352)
* Fix rule handling so that eol is optional, not mandatory.
(Ian Clatworthy, #379370)
* Pushing a new stacked branch to a 1.15 smart server was broken due to a
bug in the ``BzrDirFormat.initialize_ex`` smart verb. This is fixed in
1.16, but required changes to the network protocol, so the
``BzrDirFormat.initialize_ex`` verb has been removed and replaced with a
corrected ``BzrDirFormat.initialize_ex_1.16`` verb. 1.15 clients will
still work with a 1.16 server as they will fallback to slower (and
bug-free) methods.
(Jonathan Lange, Robert Collins, Andrew Bennetts, #385132)
* Reconcile can now deal with text revisions that originated in revisions
that are ghosts. (Jelmer Vernooij, #336749)
* Support cloning of branches with ghosts in the left hand side history.
(Jelmer Vernooij, #248540)
* The ''bzr diff'' now catches OSError from osutils.rmtree and logs a
helpful message to the trace file, unless the temp directory really was
removed (which would be very strange). Since the diff operation has
succeeded from the user's perspective, no output is written to stderr
or stdout. (Maritza Mendez, #363837)
* Translate errors received from a smart server in response to a
``BzrDirFormat.initialize`` or ``BzrDirFormat.initialize_ex`` request.
This was causing tracebacks even for mundane errors like
``PermissionDenied``. (Andrew Bennetts, #381329)
Documentation
*************
* Added directory structure and started translation of docs in Russian.
(Alexey Shtokalo, Alexander Iljin, Alexander Belchenko, Dmitry Vasiliev,
Volodymyr Kotulskyi)
API Changes
***********
* Added osutils.parent_directories(). (Ian Clatworthy)
* ``bzrlib.progress.ProgressBar``, ``ChildProgress``, ``DotsProgressBar``,
``TTYProgressBar`` and ``child_progress`` are now deprecated; use
``ui_factory.nested_progress_bar`` instead. (Martin Pool)
* ``graph.StackedParentsProvider`` is now a public API, replacing
``graph._StackedParentsProvider``. The api is now considered stable and ready
for external users. (Gary van der Merwe)
* ``bzrlib.user_encoding`` is deprecated in favor of
``get_user_encoding``. (Alexander Belchenko)
* TreeTransformBase no longer assumes that limbo is provided via disk.
DiskTreeTransform now provides disk functionality. (Aaron Bentley)
Internals
*********
* Remove ``weave.py`` script for accessing internals of old weave-format
repositories. (Martin Pool)
Testing
*******
* The number of cores is now correctly detected on OSX. (John Szakmeister)
* The number of cores is also detected on Solaris and win32. (Vincent Ladeuil)
* The number of cores is also detected on FreeBSD. (Matthew Fuller)

Subject: Tutorial on working with Excel files in Python (without COM and cross
platform!) at EuroPython 2009
Message-ID: <4A3A5F66.2030701@simplistix.co.uk>
Hi All,
Too many people in the Python community *still* think the only way to
work with Excel files in Python is using COM on Windows.
To try and correct this, I'm giving a tutorial at this year's EuroPython
conference in Birmingham, UK on Monday, 29th June that will cover
working with Excel files in Python using the pure-python libraries xlrd,
xlwt and xlutils.
I'll be looking to cover:
- Reading Excel Files
Including extracting all the data types, formatting and working with
large files.
- Writing Excel Files
Including formatting, many of the useful frilly extras and writing
large excel files.
- Modifying and Filtering Excel Files
A run through of taking existing Excel files and modifying them in
various ways.
- Workshop for your problems
I'm hoping anyone who attends will get a lot out of this! If you're
planning on attending and have a particular problem you'd like to work
on in this part of the tutorial, please drop me an email and I'll try
and make sure I come prepared!
All you need for the tutorial is a working knowledge of Excel and
Python, with a laptop as an added benefit, and to be at EuroPython this
year:
http://www.europython.eu/
I look forward to seeing you all there!

Subject: xlutils 1.3.2 released!
Message-ID: <4A3AC2FD.9090102@simplistix.co.uk>
Hi All,
I'm pleased to announce a new release of xlutils. This is a small
collection of utilities that make use of both xlrd and xlwt to process
Microsoft Excel files.
The list of utilities included in this release are:
xlutils.copy
Tools for copying xlrd.Book objects to xlwt.Workbook objects.
xlutils.display
Utility functions for displaying information about xlrd-related
objects in a user-friendly and safe fashion.
xlutils.filter
A mini framework for splitting and filtering Excel files into new
Excel files.
xlutils.margins
Tools for finding how much of an Excel file contains useful data.
xlutils.save
Tools for serializing xlrd.Book objects back to Excel files.
xlutils.styles
Tools for working with formatting information expressed in styles.
A full list of changes since the last release can be found here:
http://www.simplistix.co.uk/software/python/xlutils/changes
To find out more, please read here:
http://www.simplistix.co.uk/software/python/xlutils
In case you're not aware, xlrd and xlwt are two excellent pure-python
libraries for reading and writing Excel files. They run on any platform
and, likely, any implementation of Python without the need for horrific
things like binding to Excel via COM and so needing a Windows machine.
If you use any of xlrd, xlwt or xlutils, the following google group will
be of use:
http://groups.google.com.au/group/python-excel
Hope some of this is of interest, I'd love to hear from anyone who ends
up using it!

Subject: TestFixtures 1.6.0 released!
Message-ID: <4A3AC4FF.5060200@simplistix.co.uk>
Hi All,
I'm pleased to announce the first advertised release of TestFixtures.
This is a collection of helpers and mock objects that are useful when
writing unit tests or doc tests.
The modules currently included are:
*Comparison*
This class lets you instantiate placeholders that can be used to
compared expected results with actual results where objects in the
actual results do not support useful comparison. The comparision can be
based just on the type of the object or on a partial set of the object's
attributes, both of which are particularly handy when comparing
sequences returned from tested code.
*compare*
A replacement for assertEquals and the failUnless(x() is True) pattern.
Gives more useful differences when the arguments aren't the same,
particularly for sequences and long strings.
*diff*
This function will compare two strings and give a unified diff of their
comparison. Handy as a third parameter to unittest.TestCase.assertEquals.
*generator*
This function will return a generator that yields the arguments it was
called with when the generator is iterated over.
*LogCapture*
This helper allows you to capture log messages for specified loggers in
doctests.
*log_capture*
This decorator allows you to capture log messages for specified loggers
for the duration of unittest methods.
*replace*
This decorator enables you to replace objects such as classes and
functions for the duration of a unittest method. The replacements are
removed regardless of what happens during the test.
*Replacer*
This helper enables you to replace objects such as classes and functions
from within doctests and then restore the originals once testing is
completed.
*should_raise*
This is a better version of assertRaises that lets you check the
exception raised is not only of the correct type but also has the
correct parameters.
*TempDirectory*
This helper will create a temporary directory for you using mkdtemp and
provides a handy class method for cleaning all of these up.
*tempdir*
This decorator will create a temporary directory for the duration of the
unit test and clear it up no matter the outcome of the test.
*test_date*
This is a handy class factory that returns datetime.date replacements
that have a today method that gives repeatable, specifiable, testable dates.
*test_datetime*
This is a handy class factory that returns datetime.datetime
replacements that have a now method that gives repeatable, specifiable,
testable datetimes.
*test_time*
This is a handy replacement for time.time that gives repeatable,
specifiable, testable times.
*wrap*
This is a generic decorator for wrapping method and function calls with
a try-finally and having code executed before the try and as part of the
finally.

The Foundation tries to recognize those whose assistance has been
significant in its growth and development as well as its day-to-day
operations. This quarter's Community Service Award winners are two
particularly noteworthy examples.
Stephan Deibel: Stephan was last year's outgoing chairman after four
years in harness. This year Stephan has stepped down as a director,
after helping to ensure that the Foundation's bylaws were reorganized.
Stephan developed pythonology.com to promote Python, and his work as
founder of Wingware (wingware.com) and a developer of the Wing IDE has
also had a significant impact.
Sean Reifschneider Sean has master-minded the PyCon networking every
time it's worked, and without the support of this always helpful and
reliably competent tummy.com director our conferences simply would not
have been the same.
Our thanks and congratulations go to both these recipients.

Subject: MailingLogger 3.3.0 Released!
Message-ID: <4A3B4492.9030003@simplistix.co.uk>
I'm pleased to announce a new release of Mailinglogger.
Mailinglogger provides two handlers for the standard python
logging framework that enable log entries to be emailed either as the
entries are logged or as a summary at the end of the running process.
The handlers have the following features:
- customisable and dynamic subject lines for emails sent
- emails sent with an X-Mailer header for easy filtering
- flood protection to ensure the number of emails sent is not excessive
- support for SMTP servers that require authentication
- fully documented and tested
In addition, extra support is provided for configuring the handlers when
using ZConfig, Zope 2 or Zope 3.
The latest releases of ZConfig, in particular, provide a great way to
configure the python logging framework without having to resort to the
appalling .ini-based configuration stuff:
>>> from ZConfig import configureLoggers
>>> configureLoggers('''
...
... level INFO
...
... PATH STDOUT
... format %(levelname)s %(name)s %(message)s
...
...
... ''')
This release of MailingLogger adds the ability to use %(levelname)s in
subject-line formatting for SummarisingLoggers to include the highest
level logged.

Subject: ErrorHandler 1.0.0 Released!
Message-ID: <4A3B5887.6000509@simplistix.co.uk>
I'm pleased to finally get around to announcing the release of ErrorHandler.
This is a handler for the python standard logging framework that can
be used to tell whether messages have been logged at or above a
certain level.
This can be useful when wanting to ensure that no errors have been
logged before committing data back to a database.
Here's an example:
First, you set up the error handler:
>>> from logging import getLogger
>>> from errorhandler import ErrorHandler
>>> logger = getLogger()
>>> e = ErrorHandler()
The handler started off being un-fired:
>>> e.fired
False
Then you do whatever else you need to do, which may involve logging:
>>> logger.info('some information')
>>> e.fired
False
However, if any logging occurs at an error level or above:
>>> logger.error('an error')
Then the error handler becomes fired:
>>> e.fired
True
You use this as a condition to only do certain actions when no errors
have been logged:
>>> if e.fired:
... print "Not updating files as errors have occurred"
Not updating files as errors have occurred
If your code does work in batches, you may wish to reset the error
handler at the start of each batch:
>>> e.reset()
>>> e.fired
False

much improved image sizing, nicer list layouts, better styling, page
backgrounds, and more than 15 bugs fixed. A full changelog is included at the
bottom of this message.
Rst2pdf aims to support the full restructured text feature set, and is very
close to that goal, while also including some of the more experimental
features, like a source code directive with syntax highlighting and math
notation support with LaTeX-like syntax.
It supports embedding arbitrary fonts, both True Type and PS Type 1, both
raster and vector images (including SVG), page transition effects, multiple,
flexible page layouts, cascading styles, and much, much more.
You can find more information about rst2pdf in its home page (
http://rst2pdf.googlecode.com), and ask anything you want in the rst2pdf-
discuss mailing list (http://groups.google.com/group/rst2pdf-discuss)
Here are the changes in this version compared to 0.10.1:
* Degrade more gracefully when one or more wordaxe hyphenators are
broken (currently DWC is the broken one)
* Fixed issue 132: in some cases, with user-defined fontAlias, bold and
italic would get confused (getting italic instead of bold in inline
markup, for instance).
* New stylesheet no-compact-lists to make lists... less compact
* SVG images now handle % as a width unit correctly.
* Implemented issue 127: support images in PDF format. Right now they
are rasterized, so it's not ideal. Perhaps something better will come up
later.
* Fixed issue 129: make it work around a prblem with KeepTogether in RL 2.1
it probably makes the output look worse in some cases when using that.
RL 2.1 is not really supported, so added a warning.
* Fixed issue 130: use os.pathsep instead of ":" since ":" in windows is used
in disk names (and we still pay for DOS idiocy, in 2009)
* Fixed issue 128: headings level 3+ all looked the same
* Ugly bugfix for Issue 126: crashes when using images in header + TOC
* New tstyles section in the stylesheet provides more configurable list
layouts
and more powerful table styling.
* Better syntax highlighting (supports bold/italic)
* Workaround for issue 103 so you can use borderPadding as a list (but it will
look wrong
if you are using wordaxe <= 0.3.2)
* Added fieldvalue style for field lists
* Added optionlist tstyle, for option lists
* Added collection of utility stylesheets and documented it
* Improved command line parsing and stylesheet loading (guess
extension like latest rst2latex does)
* Fixed Issue 67: completely new list layouting code
* Fixed Issue 116: crashes caused by huge images
* Better support for %width in images, n2ow it's % of the container frame's
width, not of the text area.
* Fixed bug in SVG scaling
* Better handling of missing images
* Added missing styles abstract, contents, dedication to the default
stylesheet
* Tables style support spaceBefore and spaceAfter
* New topic-title style for topic titles (obvious ;-)
* Vertical alignment for inline images (:align: parameter)
* Issue 118: Support for :scale: in images and handle resizing of inline
images
* Issue 119: Fix placement of headers and footers
* New background property for page templates (nice for presentations, for
example)
* Default to px for image width specifications instead of pt
* Support all required measurement units ("em" "ex" "px" "in" "cm"
"mm" "pt" "pc" "%" "")
* New automated scripts to check test cases for "visual differences"
* Respect images DPI property a bit like rst2latex does.
* Issue 110: New --inline-footnotes option
* Tested with reportlab from SVN trunk
* Support for Dinu Gherman's svglib. If both svglib and uniconvertor are
available,
svglib is preferred (for SVG, of course). Patch originally by rute.
* Issue 109: Separate styles for each kind of admonition
* For Issue 109: missing styles are not a fatal error
* Issue 117: TOCs with more than 6 levels now supported (raised limit to 9,
which
is silly deep)

Subject: Karrigell-3.0 released
Message-ID:
Hi there,
I am glad to announce the version 3.0 of the Python web framework
Karrigell
Karrigell has been around since 2002 and after numerous versions,
until 2.4.0 last year, it needed a complete rewriting. Some modules
had been written long ago, using out-of-date patterns ; the global
architecture needed cleaning up, to replace an accumulation of modules
added one release after the other ; most important, the previous
versions were unable to run reliably in a multithreaded environment,
which was a serious limitation for professional web developement
The decision was taken more than one year ago to rewrite almost
everything, while stricking to the same guidelines of simplicity for
the programmer and administrator :
- no configuration needed to get started : just unzip the package and
run "python Karrigell.py" to start the built-in web server
- URLs match scripts in the file system
- no imposed ORM, templating engine : all you need to know is Python
and HTML, plus a few built-in names for access to environment, form
data, etc
- the most usual tasks in web programing (sessions, user management,
redirection, etc) are accessible though built-in functions and
exceptions with a very intuitive syntax : Session() returns the
session object, Login() checks if a user is logged in and redirects to
a login page otherwise, "raise HTTP_REDIRECTION, url" redirects to the
specified url, etc
- clear debugging info
- a choice between a variety of coding styles : while the recommended
way is to use "Karrigell services" (Python scripts with the whole
logic of a web application in one script), other options are possible,
including a PHP-like format with Python code inside HTML markup
The most efficient and flexible way to run Karrigell is to use the
built-in multithreaded or multi-process web server ; for Windows user,
an exe file is available and allows running the framework from a USB
key on any machine, even if no Python interpreter is installed. The
built-in server has been tested by hundreds of users on all possible
configurations, it is robust, reliable and fast enough for 99% of web
sites
Of course, it can also be integrated to other web servers, with a
special effort on Apache integration (CGI mode, mod_python) ; you can
also configure your server to serve static files and proxy the
requests to the built-in server
Karrigell does not impose anything on database choice : since scripts
are pure Python, any db engine with a Python API can be used, either
directly or through an ORM like SQLAlchemy. All template engines are
also supported
Though it's an almost complete rewriting, the syntax remains almost
100% compatible with previous versions. Migrating from 2.x to 3.0
should be easy (much easier than from Python 2.x to 3.0). The two main
changes, introduced for multithread support, are relative to :
- relative paths in the file system : in previous versions, they were
converted to absolute path relative to the script's path ; in version
3.0, they must be converted by a built-in function REL()
- import of user-defined modules : instead of the standard Python
statement "import foo", the syntax is now foo = Import("foo")
A tool to detect potential migration issues in provided in the package
I thank all the people on the Karrigell group who helped by their
advices, suggestions, support and code
Enjoy !

Subject: discover: automatic test discovery for unittest
Message-ID: <3d8b8b38-5254-4b3e-963d-e10950b6b3cb@l34g2000vbi.googlegroups.com>
The discover module is a backport of the automatic test discovery from
python-trunk (what will become Python 2.7 & 3.2) to work with Python
2.4 or more recent (including Python 3.0).
Test discovery allows you to run all the unittest based tests (or just
a subset of them) in your project without you having to write your own
test collection or running machinery. Once installed, test discovery
can be invoked with ``python -m discover``. I've tested the discover
module with Python 2.4 and 3.0.
The discover module also implements the ``load_tests`` protocol which
allows you to customize test loading from modules and packages. Test
discovery and ``load_tests`` are implemented in the
``DiscoveringTestLoader`` which can be used from your own test
framework.
* discover module on PyPI http://pypi.python.org/pypi/discover
discover can be installed with pip or easy_install. After installing
switch the
current directory to the top level directory of your project and run::
python -m discover
python discover.py
This will discover all tests (with certain restrictions) from the
current
directory. The discover module has several options to control its
behavior (full
usage options are displayed with ``python -m discover -h``)::
Usage: discover.py [options]
Options:
-v, --verbose Verbose output
-s directory Directory to start discovery ('.' default)
-p pattern Pattern to match test files ('test*.py'
default)
-t directory Top level directory of project (default to
start directory)
For test discovery all test modules must be importable from the
top
level directory of the project.
For example to use a different pattern for matching test modules run::
python -m discover -p '*test.py'
(Remember to put quotes around the test pattern or shells like bash
will do
shell expansion rather than passing the pattern through to discover.)
Test discovery is implemented in
``discover.DiscoveringTestLoader.discover``. As
well as using discover as a command line script you can import
``DiscoveringTestLoader``, which is a subclass of
``unittest.TestLoader``, and
use it in your test framework.
This method finds and returns all test modules from the specified
start
directory, recursing into subdirectories to find them. Only test files
that
match *pattern* will be loaded. (Using shell style pattern matching.)
All test modules must be importable from the top level of the project.
If
the start directory is not the top level directory then the top level
directory must be specified separately.
The ``load_tests`` protocol allows test modules and packages to
customize how
they are loaded. This is implemented in
``discover.DiscoveringTestLoader.loadTestsFromModule``. If a test
module defines
a ``load_tests`` function then tests are loaded from the module by
calling
``load_tests`` with three arguments: `loader`, `standard_tests`,
`None`.
If a test package name (directory with `__init__.py`) matches the
pattern then the package will be checked for a ``load_tests``
function. If this exists then it will be called with *loader*,
*tests*,
*pattern*.
If ``load_tests`` exists then discovery does *not* recurse into the
package,
``load_tests`` is responsible for loading all tests in the package.
The pattern is deliberately not stored as a loader attribute so that
packages can continue discovery themselves. *top_level_dir* is stored
so
``load_tests`` does not need to pass this argument in to
``loader.discover()``.
discover.py is maintained in a google code project (where bugs and
feature
requests should be posted): http://code.google.com/p/unittest-ext/
The latest development version of discover.py can be found at:
http://code.google.com/p/unittest-ext/source/browse/trunk/discover.py

Subject: [ANNOUNCE] PyGTK 2.15.2 - unstable
Message-ID: <35bf41160906210144y67826b56l786e053de2615eca@mail.gmail.com>
A new unstable development release of the Python bindings
for GTK+ has been released.
The new release is available from ftp.gnome.org and its mirrors
as soon as its synced correctly:
http://ftp.gnome.org/pub/GNOME/sources/pygtk/2.15/
Thanks to Paul Pogonyshev who has done all the hard job preparing this release.
Blurb:
GTK+ is a toolkit for developing graphical applications that run on
systems such as Linux, Windows and MacOS X. It provides a comprehensive set
of GUI widgets, can display Unicode bidi text. It links into the Gnome
Accessibility Framework through the ATK library.
PyGTK provides a convenient wrapper for the GTK+ library for use in
Python programs, and takes care of many of the boring details such as
managing memory and type casting. When combined with PyORBit and
gnome-python, it can be used to write full featured Gnome applications.
Like the GTK+ library itself PyGTK is licensed under the GNU LGPL, so is
suitable for use in both free software and proprietary applications. It
is already in use in many applications ranging from small single purpose
scripts up to large full features applications.
What's new since 2.15.1?
- Rename gtk.Statusbar.remove() to gtk.Statusbar.remove_message (Paul)
- Allow pango.Context creation (Paul, #550855)
- Make gtk.gdk.Pixbuf.add_alpha accept integers, retaining backward
compatibility accepting also chars (Paul, #586094)
- Protect window obj from GC in gtk.window_get_toplevels (Gustavo, #574259)
- Plug huge number of memory leaks in Pango wrappers (Paul)
- Add gtk.gdk.WINDOWING constant (Paul, #555112)
- Wrap gdk_pixbuf_apply_embedded_orientation (Chris Wilson)
- Modernize constructors of seven more types (Paul)
- Don't free a string we don't own (Paul, #585458)
- Some docs tweaking (Gian)
Bug reports, as always, should go to Bugzilla; check out
http://pygtk.org/developer.html and http://pygtk.org/feedback.html for
links to posting and querying bug reports for PyGTK.
cheers

Subject: [ANN] PuDB 0.92.1 - a console-based visual debugger
Message-ID: <200906220250.54386.inform@tiker.net>
What is it?
-----------
PuDB is a full-screen, console-based visual debugger for Python.
Its goal is to provide all the niceties of modern GUI-based debuggers in a
more lightweight and keyboard-friendly package. PuDB allows you to debug code
right where you write and test it--in a terminal. If you've worked with the
excellent (but nowadays ancient) DOS-based Turbo Pascal or C tools, PuDB's UI
might look familiar.
Where can I get it?
--------------------
You may find the most recent version (0.92.1 as of this writing) here:
http://pypi.python.org/pypi/pudb
(like screencasts? there is one!)
Main Features
-------------
* Syntax-highlighted source, the stack, breakpoints and variables are all
visible at once and continuously updated. This helps you be more aware of
what's going on in your program. Variable displays can be expanded, collapsed
and have various customization options.
* Simple, keyboard-based navigation using single keystrokes makes debugging
quick and easy. PuDB understands cursor-keys and Vi shortcuts for navigation.
Other keys are inspired by the corresponding pdb coomands.
* Use search to find relevant source code, or use "m" to invoke the module
browser that shows loaded modules, lets you load new ones and reload existing
ones.
* Breakpoints can be set just by pointing at a source line and hitting "b" and
then edited visually in the breakpoints window. Or hit "t" to run to the line
under the cursor.
* Drop to a Python shell in the current environment by pressing "!".
* PuDB places special emphasis on exception handling. A post-mortem mode makes
it easy to retrace a crashing program's last steps.
License and Dependencies
------------------------
PuDB is distributed under the MIT license. It is based on Ian Ward's Urwid
library and can optionally make use of Georg Brandl's Pygments for syntax
highlighting.

Subject: ANN: HDF5 for Python 1.2
Message-ID:
Announcing HDF5 for Python (h5py) 1.2
=====================================
I'm pleased to announce the availability of HDF5 for Python 1.2 final!
This release represents a significant update to the h5py feature set.
Some of the new new features are:
- Support for variable-length strings!
- Use of built-in Python exceptions (KeyError, etc), alongside H5Error
- Top-level support for HDF5 CORE, SEC2, STDIO, WINDOWS and FAMILY drivers
- Support for ENUM and ARRAY types
- Support for Unicode file names
- Big speedup (~3x) when using single-index slicing on a chunked dataset
Main site: http://h5py.alfven.org
Google code: http://h5py.googlecode.com
What is h5py?
-------------
HDF5 for Python (h5py) is a general-purpose Python interface to the
Hierarchical Data Format library, version 5. HDF5 is a versatile,
mature scientific software library designed for the fast, flexible
storage of enormous amounts of data.
>From a Python programmer's perspective, HDF5 provides a robust way to
store data, organized by name in a tree-like fashion. You can create
datasets (arrays on disk) hundreds of gigabytes in size, and perform
random-access I/O on desired sections. Datasets are organized in a
filesystem-like hierarchy using containers called "groups", and
accesed using the tradional POSIX /path/to/resource syntax.
In addition to providing interoperability with existing HDF5 datasets
and platforms, h5py is a convienient way to store and retrieve
arbitrary NumPy data and metadata.
Full list of new features in 1.2
--------------------------------
- Variable-length strings are now supported! They are mapped to native
Python strings via the NumPy "object" type. VL strings may be read,
written and created from h5py, and are allowed in all HDF5 contexts,
even as members of compound or array types.
- HDF5 exceptions now inherit from common Python built-ins like TypeError
and ValueError (in addition to current HDF5 error hierarchy), freeing
the user from knowledge of the HDF5 error system. Existing code which
uses H5Error will continue to work.
- Many different low-level HDF5 drivers can now be used when creating
a file, which allows purely in-memory ("core") files, multi-volume
("family") files, and files which use low-level buffered I/O.
- Groups and attributes now support the standard Python dictionary
interface methods, including keys(), values() and friends. The existing
methods (listnames(), listobjects(), etc.) remain and will not be
removed until at least h5py 1.4 or equivalent.
- Workaround for an HDF5 bug has sped up reading/writing of chunked
datasets. When using a slice with fewer dimensions than the dataset,
there can be as much as a 3x improvement in write times over h5py 1.1.
- Enumerated types are now fully supported; they can be used in NumPy
anywhere integer types are allowed, and are stored as native HDF5
enums. Conversion between integers and enums is supported.
- The NumPy "array" dtype is now allowed as a top-level type when
creating a dataset, not just as a member of a compound type.
- Unicode file names are now supported
- It's now possible to explicitly set the type of an attribute, and to
preserve the type of an attribute while modifying it.
- High-level objects now have .parent and .file attributes, to make the
navigation of HDF5 files more convenient.
Design revisions since 1.1
--------------------------
- The role of the "name" attribute on File objects has changed. "name"
now returns the HDF5 path of the File object ('/'); the file name on
disk is available at File.filename.
- Dictionary-interface methods for Group and AttributeManager objects have
been renamed to follow the standard Python convention (keys(), values(),
etc). The old method names are still available but deprecated.
- The HDF5 shuffle filter is no longer automatically activated when
GZIP or LZF compression is used; many datasets "in the wild" do not
benefit from shuffling.
Standard features
-----------------
- Supports storage of NumPy data of the following types:
* Integer/Unsigned Integer
* Float/Double
* Complex/Double Complex
* Compound ("recarray")
* Strings
* Boolean
* Array
* Enumeration (integers)
* Void
- Random access to datasets using the standard NumPy slicing syntax,
including a subset of fancy indexing and point-based selection
- Transparent compression of datasets using GZIP, LZF or SZIP,
and error-detection using Fletcher32
- "Pythonic" interface supporting dictionary and NumPy-array metaphors
for the high-level HDF5 abstrations like groups and datasets
- A comprehensive, object-oriented wrapping of the HDF5 low-level C API
via Cython, in addition to the NumPy-like high-level interface.
- Supports many new features of HDF5 1.8, including recursive iteration
over entire files and in-library copy operations on the file tree
- Thread-safe
Where to get it
---------------
* Main website, documentation: http://h5py.alfven.org
* Downloads, bug tracker: http://h5py.googlecode.com
Requires
--------
* Linux, Mac OS-X or Windows
* Python 2.5 (Windows), Python 2.5 or 2.6 (Linux/Mac OS-X)
* NumPy 1.0.3 or later
* HDF5 1.6.5 or later (including 1.8); HDF5 is included with
the Windows version.
Thanks
------
Thanks to D. Dale, E. Lawrence and other for their continued support
and comments. Also thanks to the Francesc Alted and the PyTables project,
for inspiration and generously providing their code to the community. Thanks
to everyone at the HDF Group for creating such a useful piece of software.

Subject: ANN: Numexpr 1.3.1 released
Message-ID: <200906231426.29207.faltet@pytables.org>
==========================
Announcing Numexpr 1.3.1
==========================
Numexpr is a fast numerical expression evaluator for NumPy. With it,
expressions that operate on arrays (like "3*a+4*b") are accelerated
and use less memory than doing the same calculation in Python.
This is a maintenance release. On it, support for the `unit32` type
has been added (it is internally upcasted to `int64`), as well as a
new `abs()` function (thanks to Pauli Virtanen for the patch).
Also, a little tweaking in the treatment of unaligned arrays on Intel
architectures allowed for up to 2x speedups in computations involving
unaligned arrays. For example, for multiplying 2 arrays (see the
included ``unaligned-simple.py`` benchmark), figures before the
tweaking were:
NumPy aligned: 0.63 s
NumPy unaligned: 1.66 s
Numexpr aligned: 0.65 s
Numexpr unaligned: 1.09 s
while now they are:
NumPy aligned: 0.63 s
NumPy unaligned: 1.65 s
Numexpr aligned: 0.65 s
Numexpr unaligned: 0.57 s <-- almost 2x faster than above
You can also see how the unaligned case can be even faster than the
aligned one. The explanation is that the 'aligned' array was actually
a strided one (actually a column of an structured array), and the
total working data size was a bit larger for this case.
In case you want to know more in detail what has changed in this
version, see:
http://code.google.com/p/numexpr/wiki/ReleaseNotes
or have a look at RELEASE_NOTES.txt in the tarball.
Where I can find Numexpr?
=========================
The project is hosted at Google code in:
http://code.google.com/p/numexpr/
And you can get the packages from PyPI as well:
http://pypi.python.org/pypi
How it works?
=============
See:
http://code.google.com/p/numexpr/wiki/Overview
for a detailed description by the original author (David M. Cooke).
Share your experience
=====================
Let us know of any bugs, suggestions, gripes, kudos, etc. you may
have.
Enjoy!

Subject: Guppy-PE/Heapy 0.1.9 released
Message-ID: <3ce5e889-1490-49d0-95f1-13e7fad66870@r37g2000yqd.googlegroups.com>
I am happy to announce Guppy-PE 0.1.9
Guppy-PE is a library and programming environment for Python,
currently providing in particular the Heapy subsystem, which supports
object and heap memory sizing, profiling and debugging. It also
includes a prototypical specification language, the Guppy
Specification Language (GSL), which can be used to formally specify
aspects of Python programs and generate tests and documentation from a
common source.
The main news in this release:
o A patch by Chad Austin to compile with Visual Studio 2003 and Python
2.5 C compilers. I think this may fix similar problems with other
Microsoft compilers.
o Interactive help system, providing a .doc attribute that can be used
to get info on available attributes in text form and also by
invoking a browser.
o New documentation file, heapy_tutorial.html. It contains for now an
example of how to get started and use the interactive help.
o Bug fix wrt pop for mutable bitset. (Not used in heapy, only in
sets/test.py)
o guppy.hpy().test() now includes the set-specific tests.
o Remote monitor does not longer require readline library being
installed.

Subject: CodeInvestigator version 0.13.0 was released on June 24
Message-ID: <6d0c06ff-cddf-43db-a0cf-3d2709d00cda@x29g2000prf.googlegroups.com>
CodeInvestigator version 0.13.0 was released on June 24.
Bug fix:
Changes to imported files were not taken into account.
This version only works with Python 2.6.
Some modules disappear in Python 3.0 and this version has these
modules replaced.
CodeInvestigator is a tracing tool for Python programs.
Running a program through CodeInvestigator creates a recording.
Program flow, function calls, variable values and conditions are all
stored for every line the program executes.
The recording is then viewed with an interface consisting of the
code. The code can be clicked: A clicked variable displays its
value,
a clicked loop displays its iterations.
You read code, and have at your disposal all the run time details of
that code. A computerized desk check tool and another way to learn
about your program.

Hi all,
timelib is a short wrapper around php's internal timelib module.
It currently only provides two functions for parsing textual date descriptions:
timelib.strtodatetime:
>>> timelib.strtodatetime('today')
datetime.datetime(2009, 6, 23, 0, 0)
>>> timelib.strtodatetime('today')
datetime.datetime(2009, 6, 23, 0, 0)
>>> timelib.strtodatetime('next friday')
datetime.datetime(2009, 6, 26, 0, 0)
>>> timelib.strtodatetime('29 feb 2008 -108 years')
datetime.datetime(1900, 3, 1, 0, 0)
timelib.strtotime:
>>> import time, timelib
>>> time.ctime(timelib.strtotime("now"))
'Tue Jun 23 15:17:32 2009'
>>> time.ctime(timelib.strtotime("4 hours ago"))
'Tue Jun 23 11:17:38 2009'
>>> time.ctime(timelib.strtotime("20080229 -1 year"))
'Thu Mar 1 01:00:00 2007'
timelib is available via PyPI:

Subject: bzr 1.16.1 released!
Message-ID:
We discovered a couple of bugs in the 1.16 release that we simply had
to fix now. As such...
The Bazaar team is mostly happy & just a little bit embarrassed to
announce availability of a new release of the bzr adaptive version
control system. Bazaar is part of the GNU system .
End user testing of the 2a format revealed two serious bugs. The
first, #365615, caused bzr to raise AbsentContentFactory errors when
autopacking. This meant that commits or pushes to 2a-format
repositories failed intermittently.
The second bug, #390563, caused the smart server to raise
AbsentContentFactory when streaming 2a stacked 2a-format branches.
This particularly affected branches stored on Launchpad in the 2a
format.
Both of these bugs cause command failures only, neither of them cause
data corruption or data loss. And, of course, both of these bugs are
now fixed.
Thanks in particular to Robert Collins and John Arbash Meinel for
fixing these bugs.
Bazaar is now available for download from
http://bazaar-vcs.org/Download as a source tarball; packages for
various systems will be available soon.
Bug Fixes
*********
* We now properly request a more minimal set of file texts when fetching
multiple revisions. (Robert Collins, John Arbash Meinel, #390563)
* Repositories using CHK pages (which includes the new 2a format) will no
longer error during commit or push operations when an autopack operation
is triggered. (Robert Collins, #365615)
* ``chk_map.iter_interesting_nodes`` now properly uses the *intersection*
of referenced nodes rather than the *union* to determine what
uninteresting pages we still need to look at. Prior to this,
incrementally pushing to stacked branch would push the minimal data, but
fetching everything would request extra texts. There are some unhandled
cases wrt trees of different depths, but this fixes the common cases.
(Robert Collins, John Arbash Meinel, #390563)
* ``GroupCompress`` repositories now take advantage of the pack hints
parameter to permit cross-format fetching to incrementally pack the
converted data. (Robert Collins)
* ``Repository.commit_write_group`` now returns opaque data about what
was committed, for passing to the ``Repository.pack``. Repositories
without atomic commits will still return None. (Robert Collins)
* ``Repository.pack`` now takes an optional ``hint`` parameter
which will support doing partial packs for repositories that can do
that. (Robert Collins)
* RepositoryFormat has a new attribute 'pack_compresses' which is True
when doing a pack operation changes the compression of content in the
repository. (Robert Collins)
* ``StreamSink`` and ``InterDifferingSerialiser`` will call
``Repository.pack`` with the hint returned by
``Repository.commit_write_group`` if the formats were different and the
repository can increase compression by doing a pack operation.

Subject: Nagare 0.2.0 - Components and continuation-based web framework
Message-ID: <200906261240.22240.alain.poirier@net-ng.com>
Hi all,
The version 0.2.0 of the Nagare web framework is now released !

About Nagare
============
Nagare is a components based framework: a Nagare application
is a composition of interacting components each one with its
own state and workflow kept on the server. Each component
can have one or several views that are composed to generate
the final web page. This enables the developers to reuse or
write highly reusable components easily and quickly.
Thanks to Stackless Python, Nagare is also a continuation-based
web framework which enables to code a web application like a
desktop application, with no need to split its control flow in
a multitude of controllers and with the automatic handling of
the back, fork and refresh actions from the browser.
Its component model and use of the continuation come from the
famous Seaside Smalltalk framework.
Furthermore Nagare integrates the best tools and standard from
the Python world. For example:
- WSGI: binds the application to several possible publishers,
- lxml: generates the DOM trees and brings to Nagare the full
set of XML features (XSL, XPath, Schemas ...),
- setuptools: installs, deploys and extends the Nagare framework
and the Nagare applications too,
- PEAK Rules: generic methods are heavily used in Nagare, to
associate views to components, to define security rules, to
translate Python code to Javascript ...
- WebOb: for its Request and Response Objects.
Examples
========
A complete "guess a number" game to taste how easy web coding
becomes using continuations:
import random
from nagare import component, util
class Number(component.Task):
"""A little game to guess a number
"""
def go(self, comp):
"""The game algorithm, using continuation for a pure linear Python code
In:
- ``comp`` -- this component
"""
self.attempt = 1
number = random.randint(1, 20)
comp.call(util.Confirm('I choose a number between 1 and 20. Try to guess
it'))
while True:
x = comp.call(util.Ask('Try #%d: ' % self.attempt))
if not x.isdigit():
continue
x = int(x)
if x > number:
comp.call(util.Confirm('Choose a lower number'))
if x < number:
comp.call(util.Confirm('Choose a greater number'))
if x == number:
comp.call(util.Confirm('You guessed the number in %d attempts' %
self.attempt))
break
self.attempt += 1
A simple todo list, illustrating the programmatic HTML generation,
the association of view(s) to Python objects and the direct association
of callbacks to HTML form elements and links:
from nagare import presentation
from nagare.namespaces import xhtml
# A plain Python ``TodoList`` class
class TodoList(object):
def __init__(self):
self.todo = []
def add_todo(self, msg):
self.todo.append(msg)
# The default HTML view, generated in programmatic HTML
@presentation.render_for(TodoList)
def render(self, h, comp, model):
# ``h`` is a (X)HTML renderer
(http://www.nagare.org/trac/wiki/RendererObjects)
with h.div:
for msg in self.todo:
h << h.blockquote(msg) << h.hr
with h.form:
h << 'New todo:' << h.br
h << h.textarea.action(self.add_todo) << h.br
h << h.input(type='submit', value='Add')
return h.root

Subject: [RELEASED] Python 3.1 final
Message-ID: <1afaf6160906271412v3ca3ef9bo4efa4523db3a3685@mail.gmail.com>
On behalf of the Python development team, I'm thrilled to announce the first
production release of Python 3.1.
Python 3.1 focuses on the stabilization and optimization of the features and
changes that Python 3.0 introduced. For example, the new I/O system has been
rewritten in C for speed. File system APIs that use unicode strings now handle

Subject: ANN: SciPy 2009 student sponsorship
Message-ID:
I am pleased to announce that the Python Software Foundation is
sponsoring 10 students' travel, registration, and accommodation for
the SciPy 2009 conference (Aug. 18-23). The focus of the conference
is both on scientific libraries and tools developed with Python and on
scientific or engineering achievements using Python. If you're in
college or a graduate program, please check out the details here:
http://conference.scipy.org/student-funding
About the conference
--------------------
SciPy 2009, the 8th Python in Science conference, will be held from
August 18-23, 2009 at Caltech in Pasadena, CA, USA. The conference
starts with two days of tutorials to the scientific Python tools.
There will be two tracks, one for introduction of the basic tools to
beginners, and one for more advanced tools. The tutorials will be
followed by two days of talks. Both days of talks will begin with a
keynote address. The first day?s keynote will be given by Peter
Norvig, the Director of Research at Google; while, the second keynote
will be delivered by Jon Guyer, a Materials Scientist in the
Thermodynamics and Kinetics Group at NIST. The program committee will
select the remaining talks from submissions to our call for papers.
All selected talks will be included in our conference proceedings
edited by the program committee. After the talks each day we will
provide several rooms for impromptu birds of a feather discussions.
Finally, the last two days of the conference will be used for a number
of coding sprints on the major software projects in our community.
For the 8th consecutive year, the conference will bring together the
developers and users of the open source software stack for scientific
computing with Python. Attendees have the opportunity to review the
available tools and how they apply to specific problems. By providing
a forum for developers to share their Python expertise with the wider
commercial, academic, and research communities, this conference
fosters collaboration and facilitates the sharing of software
components, techniques, and a vision for high level language use in
scientific computing.
For further information, please visit the conference homepage:

Subject: ANN: eGenix mxODBC Connect 1.0.2 - Python Database Interface
Message-ID: <4A488440.5040107@egenix.com>
________________________________________________________________________
ANNOUNCING
eGenix.com mxODBC Connect
Python Database Interface
Version 1.0.2
Our new client-server product for connecting Python applications
to relational databases - from all major platforms
This announcement is also available on our web-site for online reading:
http://www.egenix.com/company/news/eGenix-mxODBC-Connect-1.0.2-GA.html
________________________________________________________________________
INTRODUCTION
The mxODBC Connect Database Interface for Python allows users to
easily connect Python applications to all major databases on the
market today in a highly portable and convenient way.
Unlike our mxODBC Python extension, mxODBC Connect is designed
as client-server application, so you no longer need to find production
quality ODBC drivers for all the platforms you target with your Python
application.
Instead you use an easy to install Python client library which
connects directly to the mxODBC Connect database server over the
network.
This makes mxODBC Connect the ideal basis for writing cross-platform
database programs and utilities in Python, especially if you run
applications that need to communicate with databases such as MS SQL
Server and MS Access, Oracle Database, IBM DB2 and Informix, Sybase
ASE and Sybase Anywhere, MySQL, PostgreSQL, SAP MaxDB and many more,
that run on Windows or Linux machines.
By removing the need to install and configure ODBC drivers on the
client side, mxODBC Connect greatly simplifies setup and
configuration of database driven client applications, while at
the same time making the network communication between client and
database server more efficient and more secure.
For more information, please see the product page:
http://www.egenix.com/products/python/mxODBCConnect/
________________________________________________________________________
NEWS
mxODBC Connect 1.0.2 is a patch-level release of our new mxODBC Connect
product.
* More Secure
We have upgraded the server to our latest eGenix pyOpenSSL release
0.9.0-0.9.8k, which includes a number of important bug fixes to both
pyOpenSSL and the used OpenSSL library.
* More Robust
Previous versions had a timeout issue that we have solved with this
release. We have have also added a special case for shutting down the
client with a broken server connection. In such cases, the client will
no longer wait for a timeout and terminate much faster.
* Ideal for Building Bridges
mxODBC Connect Client now works on all major Python platforms. As a
result, connecting from e.g. Linux or Mac OS X to an SQL Server
database has never been easier. You can even keep the data sources you
already have configured on your Windows machine and connect to them as
if your application were running on the database server itself.
________________________________________________________________________
UPGRADING
You are encouraged to upgrade to this latest mxODBC Connect release.
When upgrading, please always upgrade both the server and the client
installations to the same version - even for patch level releases.
Customers who have purchased mxODBC Connect 1.0 licenses can download
and upgrade their existing installations without having to purchase
new licenses or upgrades. The licenses will continue to work with
version 1.0.2.
Users of our stand-alone mxODBC product will have to purchase new
licenses from our online shop in order to use mxODBC Connect.
You can request 30-day evaluation licenses by visiting our web-site
or writing to sales at egenix.com, stating your name (or the name of the
company) and the number of eval licenses that you need.
