[ANN] argparse 0.3 - Command-line parsing library
by Steven Bethard Dec. 5, 2006

Dec. 5, 2006

Announcing argparse 0.3 ----------------------- argparse home: http://argparse.python-hosting.com/ argparse single module download: http://argparse.python-hosting.com/file/trunk/argparse.py?format=raw argparse bundled downloads at PyPI: http://www.python.org/pypi/argparse/ About this release ================== This release moves argparse's development status from Pre-Alpha to Alpha. The API is basically stable, though reasonable change requests will still be considered. New in this release =================== * The '--' pseudo-argument can now be used to terminate the arg list of an optional:: >>> parser = argparse.ArgumentParser() >>> parser.add_argument('-x', nargs='+') >>> parser.add_argument('y') >>> parser.parse_args('-x X1 X2 X3 -- Y'.split()) Namespace(x=['X1', 'X2', 'X3'], y='Y') About argparse ============== The argparse module is an optparse-inspired command line parser that improves on optparse by: * handling both optional and positional arguments * supporting parsers that dispatch to sub-parsers * producing more informative usage messages * supporting actions that consume any number of command-line args * allowing types and actions to be specified with simple callables instead of hacking class attributes like STORE_ACTIONS or CHECK_METHODS as well as including a number of other more minor improvements on the optparse API. To whet your appetite, here's a simple program that sums its command-line arguments and writes them to a file:: parser = argparse.ArgumentParser() parser.add_argument('integers', type=int, nargs='+') parser.add_argument('--log', type='outfile', default=sys.stdout) args = parser.parse_args() args.log.write('%s\n' % sum(args.integers)) args.log.close()

PyPy Leysin Winter Sports Sprint (8-14th January 2007)
by Carl Friedrich Bolz Dec. 5, 2006

Dec. 5, 2006

===================================================================== PyPy Leysin Winter Sports Sprint (8-14th January 2007) ===================================================================== .. image:: http://www.ermina.ch/002.JPG The next PyPy sprint will be in Leysin, Switzerland, for the fourth time. This sprint will be the final public sprint of our EU-funded period, and a kick-off for the final work on the upcoming PyPy 1.0 release (scheduled for mid-February). The sprint is the last chance for students looking for a "summer" job with PyPy this winter! If you have a proposal and would like to work with us in the mountains please send it in before 15th December to "pypy-tb at codespeak.net" and cross-read this page: http://codespeak.net/pypy/dist/pypy/doc/summer-of-pypy.html ------------------------------ Goals and topics of the sprint ------------------------------ * Like previous winter, the main side goal is to have fun in winter sports :-) We can take a couple of days off for ski; at this time of year, ski days end before 4pm, which still leaves plenty of time to recover (er, I mean hack). * Progress on the JIT compiler, which we are just starting to scale to the whole of PyPy. `[1]`_ * Polish the code and documentation of the py lib, and eventually release it. * Work on prototypes that use the new features that PyPy enables: distribution `[2]`_ (based on transparent proxying `[3]`_), security `[4]`_, persistence `[5]`_, etc. `[6]`_. .. _[1]: http://codespeak.net/pypy/dist/pypy/doc/jit.html .. _[2]: http://codespeak.net/svn/pypy/dist/pypy/lib/distributed/ .. _[3]: http://codespeak.net/pypy/dist/pypy/doc/proxy.html .. _[4]: http://codespeak.net/pypy/dist/pypy/doc/project-ideas.html#security .. _[5]: http://codespeak.net/pypy/dist/pypy/doc/project-ideas.html#persistence .. _[6]: http://codespeak.net/pypy/dist/pypy/doc/project-ideas.html ----------------------- Location & Accomodation ----------------------- Leysin, Switzerland, "same place as before". Let me refresh your memory: both the sprint venue and the lodging will be in a very spacious pair of chalets built specifically for bed & breakfast: http://www.ermina.ch/. The place has a baseline ADSL Internet connexion (600Kb) with wireless installed. You can of course arrange your own lodging anywhere (so long as you are in Leysin, you cannot be more than a 15 minute walk away from the sprint venue), but I definitely recommend lodging there too -- you won't find a better view anywhere else (though you probably won't get much worse ones easily, either :-) I made pre-reservations in the Chalet, so please *confirm* quickly that you are coming so that we can adjust the reservations as appropriate. The rate so far has been 60 CHF a night all included in 2-person rooms, with breakfast. There are larger rooms too (less expensive, possibly more available too) and the possibility to get a single room if you really want to. Please register by svn: http://codespeak.net/svn/pypy/extradoc/sprintinfo/leysin-winter-2007/people… or on the pypy-sprint mailing list if you do not yet have check-in rights: http://codespeak.net/mailman/listinfo/pypy-sprint You need a Swiss-to-(insert country here) power adapter. There will be some Swiss-to-EU adapters around - bring a EU-format power strip if you have one. ----------- Exact times ----------- Officially, 8th-14th January 2007. Both dates are flexible, you can arrive or leave earlier or later, though it is recommended to arrive on the 7th (if many people arrive on the 6th we need to check for accomodation availability first). We will give introductions and tutorials on the 8th, in the morning if everybody is there, or in the afternoon otherwise.

ANN: PIL 1.1.6 final (december 3, 2006)
by Fredrik Lundh Dec. 4, 2006

Dec. 4, 2006

The Python Imaging Library (PIL) adds image processing capabilities to your Python interpreter. This library supports many file formats, and provides powerful image processing and graphics capabilities, including display support for Windows and Tkinter. The new 1.1.6 release provides, among other things: - a new ImageQt module for image display support for PyQt4 - numerous improvements to the TrueType renderer, including proper (and crash-free) handling of fonts with negative bearings, and support for kerning. - a new ImageMath module for applying arbitrary expressions to images - faster pixel access via separate "access" objects and many more tweaks and enhancements. For a complete list, see: http://effbot.org/zone/pil-changes-116.htm You can get PIL 1.1.6 source code and binaries from: http://www.pythonware.com/products/pil PIL 1.1.6 supports all Python versions from 1.5.2 and onwards, up to and including Python 2.5. However, development of the 1.1.X line will now switch to maintenance mode, and future main releases will most likely require Python 2.3 or later. enjoy! /F "Secret Labs -- makers of fine pythonware since 1997."

Dec. 4, 2006

Hello! I'm pleased to announce the 0.7.2 release of SQLObject. What is SQLObject ================= SQLObject is an object-relational mapper. Your database tables are described as classes, and rows are instances of those classes. SQLObject is meant to be easy to use and quick to get started with. SQLObject supports a number of backends: MySQL, PostgreSQL, SQLite, and Firebird. It also has newly added support for Sybase, MSSQL and MaxDB (also known as SAPDB). Where is SQLObject ================== Site: http://sqlobject.org Mailing list: https://lists.sourceforge.net/mailman/listinfo/sqlobject-discuss Archives: http://news.gmane.org/gmane.comp.python.sqlobject Download: http://cheeseshop.python.org/pypi/SQLObject/0.7.2 News and changes: http://sqlobject.org/docs/News.html What's New ========== Features & Interface -------------------- * sqlbuilder.Select now supports JOINs exactly like SQLObject.select. * destroySelf() removes the object from related joins. Bug Fixes --------- * Fixed a number of unicode-related problems with newer MySQLdb. * If the DB API driver returns timedelta instead of time (MySQLdb does this) it is converted to time; but if the timedelta has days an exception is raised. * Fixed a number of bugs in InheritableSQLObject related to foreign keys. * Fixed a bug in InheritableSQLObject related to the order of tableRegistry dictionary. * A bug fix that allows to use SQLObject with DateTime from Zope. Documentation Added ------------------- * Added "How can I define my own intermediate table in my Many-to-Many relationship?" to FAQ. For a more complete list, please see the news: http://sqlobject.org/docs/News.html Oleg. -- Oleg Broytmann http://phd.pp.ru/ phd(a)phd.pp.ru Programmers don't die, they just GOSUB without RETURN.

Ann.: Updated TkTreectrl wrapper
by klappnase Dec. 4, 2006

Dec. 4, 2006

Hi, I have uploaded an updated version of the Tkinter wrapper for the Tk treectrl widget (http://tktreectrl.sourceforge.net). The major change in this release is the introduction of a few new widget classes: _MultiListbox_ is a Treectrl widget set up to work as a (more or less) full-featured and very flexible multi column listbox widget. The _ScrolledTreectrl_ and _ScrolledMultiListbox_ classes use ideas shamelessly stolen from Pmw.ScrolledListbox to add one or two static or automatic scrollbars to the widgets. They both inherit from the _ScrolledWidget_ class that is supposed to make it easy to add scrollbars to any other Listbox or Canvas alike Tkinter widget. Changes to the Treectrl widget: I added the second (optional) _last_ argument to column_delete() (new in treectrl-2.1.1) and fixed a few minor bugs. The url is: <http://klappnase.zexxo.net/TkinterTreectrl/index.html> Regards Michael

ANN: UliPad 3.6 released!
by limodou Dec. 4, 2006

Dec. 4, 2006

What's it? ======== It's an Editor based on wxPython. UliPad(NewEdit is the old name) uses Mixin and Plugin technique as its architecture. Most of its classes can be extended via mixin and plugin components, and finally become an integrity class at creating the instance. So UliPad is very dynamic. You can write the new features in new files, and hardly need to modify the existing code. And if you want to extend the existing classes, you could write mixins and plugins, and this will be bound to the target class that I call "Slot Class". This technique will make the changes centralized and easily managed. What's new in 3.6 ============== New features and improvement: #. Improve definition jump, and if there is no ctag file exist, UliPad can jump in one source file, including: variable, class, method, etc #. Improve auto-completion: variable auto-detect, class structure detect, base class recognize, etc. And it can improve your typing. As you backspace something, auto-completion will also available. And you can also write parameter datatype in function docstring, UliPad will auto recognize the parameter datatype. #. Add range support for live regular expression search support #. Add pairprog plugin, it's a collaborative programming support. One instance can be a server, and others can be client. For server, you can share source file with all client, and both server and client can change the same document and move the caret. UliPad support multi-client. And it has a chatroom support, so developer can use it to talk with each other. #. Add fortran, and lua syntax support. For fortran you should enable fortran plugin. #. Improve the display structure and content of class browser #. Add css auto-completion support Changes: #. Improve class browser windown, and single-click on class icon will expand or collapse the children items #. Fix the bug of clicking on Cancel button on Python Parameter Input Dialog still running #. Fix reStructuredText syntax highlight processing bug #. Fix python syntax analysis bug #. Fix cann't restore the last directories entries as reopen the directory browser bug #. Fix if the filename or directory that you want to open command line window on it(on windows platform) is not the same hard driver, will open wrong path bug. #. Fix music plugin's bug #. Remove open recently-directory functionality #. Fix as changing the encode of the document, but the tab page title doesn't be changed bug Where to download it? ================ download lastest version 3.6: http://wiki.woodpecker.org.cn/moin/UliPad?action=AttachFile&do=get&target=u… also have windows installer: http://wiki.woodpecker.org.cn/moin/UliPad?action=AttachFile&do=get&target=U… wiki: http://wiki.woodpecker.org.cn/moin/UliPad svn: http://cvs.woodpecker.org.cn/svn/woodpecker/ulipad/trunk maillist: http://groups.google.com/group/ulipad If you have any problem as using UliPad, welcome to join the UliPad maillist to discuss. Hope you enjoy it. ;-) -- I like python! UliPad <<The Python Editor>>: http://wiki.woodpecker.org.cn/moin/UliPad My Blog: http://www.donews.net/limodou

New home for adns-python
by Andy Dustman Dec. 2, 2006

Dec. 2, 2006

I had been falling behind in patches for adns-python, so I thought it would be a good idea to have a public site where it was easier for people to contribute and report bugs. The new project page is: http://code.google.com/p/adns-python Eventually I will probably add an announcements group, but there is not likely to be much traffic here for the foreseeable future. For now, there is a general discussion group: http://groups-beta.google.com/group/adns-python/ I've applied one important patch since 1.1.0, and that fixes a memory leak. If you are reading this from the Groups Beta interface, you should see a tarball for 1.1.1 in the files section; otherwise, you cannot see it. Unfortunately, there is some name-mangling and referrer detection and so it's not really possible to distribute a URL to get the file release. Additionally, code.google.com currently doesn't support flie releases, so I can't put it there, either. If you are interested in becoming a project developer, let me know. -- Patriotism means to stand by the country. It does not mean to stand by the president. -- T.
