xlutils 1.4.0 released!

[Chris Withers]

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 changes for this release are as follows:

- Add sheet density information and onesheet option to
  xlutils.margins.

- Reduced the memory footprint of xlutils.filter.ColumnTrimmer at the
  expense of speed.

- Fixed incorrect warnings about boolean cells in
  xlutils.filter.ErrorFilter. xlwt has always supported boolean
  cells.

- xlutils.filter.BaseReader now opens workbooks with on_demand = True

- Added support for xlrd Books opened with on_demand as True passed to
  open_workbook.

- Fixed bug when copying error cells.

- Requires the latest versions of xlrd (0.7.1) and xlwt (0.7.2).

To find out more, please read here:

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:

Hope some of this is of interest, I'd love to hear from anyone who ends
up using it!

cheers,

Chris

[ANN] Pyjamas 0.6 Web Widget Set and python-to-javascript Compiler released

contributed.  Special thanks to Kees Bos; Bernd, Bernd and Jurgen from
LovelySystems.com; the people who showed an interest in Pyjamas at
EuroPython 2009; and especially to everyone who has helped during the
pre-releases, with testing and bugreports over the past few weeks.

Pyjamas
---

Pyjamas is a port of Google Web Toolkit to Python, and thus enables
the development of Rich Media AJAX applications in Python, with no
need for special browser plugins.  Pyjamas contains a stand-alone
python-to-javascript compiler, and also a Widget Set API that looks
very similar to Desktop Widget Set APIs (such as PyQT4 or PyGTK2).

For more information, see:

http://pyjs.org
http://pyjs.org/FAQ.html
http://pyjs.org/features.html

Known bugs: http://code.google.com/p/pyjamas/issues
#227, #228, #229, #230 and #232

Pyjamas-Desktop
---

Pyjamas runs your application in a Web Browser (as javascript); Pyjamas-Desktop
runs exactly the same python application on the Desktop (as python)

http://pyjd.org

Release 0.6 of Pyjamas also incorporates Pyjamas-Desktop directly into
the Pyjamas Distribution.  To use Pyjamas-Desktop there are three choices,
with more planned [MacOSX PyObjC; KDE's PyKHTML].

1) - XULRunner

install hulahop and python-xpcom.  hulahop is distributed with
both Debian and Ubuntu; python-xpcom is part of XULRunner and is
also distributed with both Debian and Ubuntu.  Other users should
investigate the installation instructions for python-xpcom and
hulahop for the operating system of their choice on the appropriate
web sites.

GNU/Linux, FreeBSD and other POSIX systems are strongly advised
to use XULRunner for Pyjamas-Desktop: it is the most stable of the
PyJD ports.

2) - PyWebKitGtk

you will need a patched version of pywebkitgtk:
http://code.google.com/p/pywebkitgtk/issues/detail?id=13

you will need a patched version of webkit:
http://github.com/lkcl/webkit/16401.master

Detailed build instructions are available here:
http://wiki.github.com/lkcl/webkit/helping-with-16401master

3) - MSHTML (experimental!)

For Windows users, all that's required, other than installing python
and Internet Explorer, is one further package: Win32 comtypes.

Win32 comtypes can be downloaded here:
* http://sourceforge.net/projects/comtypes/

The MSHTML version primarily works.  Reports using IE8's MSHTML
engine would be appreciated.

Known bugs: the use of Tab to cycle through Keyboard Focus elements
is ineffective; onkeyup and onkeydown events are unresponsive,
but oddly onkeypress event handling works.
