ANN: PIL 1.1.6 alpha 1 (december 11, 2005)
by Fredrik Lundh 11 Dec '05

11 Dec '05

The first "official" PIL 1.1.6 alpha is now available from effbot.org: http://effbot.org/downloads (look for Imaging-1.1.6a1.tar.gz) Notable additions since 1.1.5: + Added pixel access object. The "load" method now returns an access object that can be used to directly get and set pixel values, using ordinary 2D array notation: pixel = im.load() v = pixel[x, y] pixel[x, y] = v If you're accessing more than a few pixels, this is a lot faster than using getpixel/putpixel. + Added buffer interface support to the Path constructor. If a buffer is provided, it is assumed to contain a flat array of float coordinates (e.g. array.array('f', seq)). + Added new ImageMath module: http://effbot.org/imagingbook/imagemath.htm and a bunch of bug fixes and minor tweaks. For a more complete list of changes, see: http://effbot.org/zone/pil-changes-116.htm enjoy /F

by Fredrik Lundh 11 Dec '05

11 Dec '05

The Widget Construction Kit (WCK) is an extension API that allows you to implement custom widgets in pure Python. The WCK can be (and is being) used for everything from light-weight display widgets to full-blown editor frameworks. The Tkinter3000 implementation of the WCK supports all recent versions of Python and Tk/Tkinter. Compared to 1.0, the 1.1 release adds improved controller support, resource caching for pens, brushes, and fonts, and support for creating image objects from data in strings. Introduction: http://www.effbot.org/zone/wck-1.htm Downloads: http://www.effbot.org/downloads#tkinter3000 Documentation: http://www.effbot.org/zone/wck.htm http://www.effbot.org/zone/pythondoc-api.htm Using WCK and AggDraw to draw anti-aliased graphics: http://www.effbot.org/zone/wck-aggview.htm enjoy /F

ANN: twill-0.8.1, Web browsing language
by C. Titus Brown 11 Dec '05

11 Dec '05

ANNOUNCING twill v0.8.1. twill is a simple language for browsing the Web. It's designed for automated testing of Web sites, but it can be used to interact with Web sites in a variety of ways. In particular, twill supports form submission, cookies, redirects, and HTTP authentication. A twill script to use the "I'm feeling lucky" button on Google looks like this: setlocal query "twill Python" go http://www.google.com/ fv 1 q $query submit btnI # use the "I'm feeling lucky" button show (Note that using this script abuses Google's Terms of Service. So don't.) This is the seventh public release of twill, version 0.8.1. You can install twill with easy_install, or download this release at http://darcs.idyll.org/~t/projects/twill-0.8.1.tar.gz Documentation is included in the .tar.gz and is also online at http://www.idyll.org/~t/www-tools/twill/ Miscellaneous details: twill is implemented in Python and uses pyparsing and mechanize. In addition to the existing simple command language, twill can easily be extended with Python. twill also provides a fairly simple and well-documented wrapper around mechanize. twill does not understand JavaScript, I'm sorry to say. --- New features: * match_parse extension (sureshvv); * formfile fix for uploading binary files (Tom Parker); * several patches for checkbox/hidden problems (tv); * Referer: headers now correctly added on form submissions (Tom Parker); * documentation reorganization.

ANN:Dict4Ini 0.3 released!
by limodou 09 Dec '05

09 Dec '05

This module is used to process ini format configuration file. It acts just like a dict, but you can also access it's sections and options with attribute syntax, just like x.test. == What's it features == * as simple as others * you can access options according to dict syntax, just like x['name']['o'] = 1, x['name'].keys(), x['name'].values(), etc. * you also can access options according to attr syntax, just like x.name.o = 1, x.name.keys(), x.name.values(), etc. So the name must be Identifier or single word. * you can save comments in it(but this feature is not tested so much) * support multi level section, subsection name will just like: [firsub/secsub] * can save config items order * support multi data types: string, unicode, int, float, list/tuple, dict, etc, you can save them to or regain them from config file * can convert to dict '''new''' * It's a little module, just for my mind, so if you like, you could try it, but if you don't like, just skip it, that's ok == Where can I download it? == * Visit the http://wiki.woodpecker.org.cn/moin/Dict4Ini site * Download it from here attachment:dict4ini.py == What's new? == * 2005/12/09 Version 0.3 * Adding dict() method, then you can change the DictIni object to dict type, so you can really use it as a dict alternative -- I like python!

imaplib module with IDLE implememted via threads
by Piers Lauder 09 Dec '05

09 Dec '05

If anyone needs the IMAP4 extension "IDLE", there is a copy of an enhanced imaplib module available for download here: http://www.cs.usyd.edu.au/~piers/python/imaplib.html This is an IMAP4rev1 mail protocol client class using threads for parallel operation. It is modified from the non-threaded version included in the standard Python distributions, but presents (a superset of) the same API. I have named this version "imaplib2" as it uses threads to implememt the necessary callbacks, and it doesn't seem necessary to burden the orginal module with requiring threading. The module has been in production use for several months, and seems stable. Piers Lauder <P><A HREF="http://www.cs.usyd.edu.au/~piers/python/imaplib.html">imaplib2</A> IMAP4rev1 mail protocol client class using threads to implement the IDLE extension. (09-Dec-2005)

[ANN] Python-OpenID 1.0
by Kevin Turner 08 Dec '05

08 Dec '05

It is with great pleasure that JanRain, Inc. announces version 1.0 of the Python OpenID library. This library contains packages to support both OpenID consumers (relying parties) and servers. For back-end storage, it supports a variety of methods, including flat file, SQL, and MemCached. In our own work on making applications OpenID enabled, we've been reminded that every web framework is different. For that reason we've strived to make this library general enough to fit in to any Python web application. We also like to think the API is simple to follow. Let us know how it works for you. Home: http://openidenabled.com/openid/libraries/python License: LGPL Download: http://openidenabled.com/openid/libraries/python/downloads/ Docs: http://openidenabled.com/python-openid-docs/1.0.0/ Requires: Python (versions 2.2 through 2.4) What is this OpenID Thing Anyway? OpenID is a decentralized identity system that provides authentication for web applications, i.e. single sign-on for the web. See http://openid.net/ If you're interested in OpenID but this library isn't quite what you've been waiting for for, keep your eye on http://openidenabled.com. There's more coming. Share and Enjoy, - the OpenID Team at JanRain openid(a)janrain.com

[ANNOUNCE] Twenty-seventh release of PythonCAD now available
by Art Haas 07 Dec '05

07 Dec '05

Hi. I'm pleased to announce the twenty-seventh development release of PythonCAD, a CAD package for open-source software users. As the name implies, PythonCAD is written entirely in Python. The goal of this project is to create a fully scriptable drafting program that will match and eventually exceed features found in commercial CAD software. PythonCAD is released under the GNU Public License (GPL). PythonCAD requires Python 2.2 or newer. The interface is GTK 2.0 based, and uses the PyGTK module for interfacing to GTK. The design of PythonCAD is built around the idea of separating the interface from the back end as much as possible. By doing this, it is hoped that both GNOME and KDE interfaces can be added to PythonCAD through usage of the appropriate Python module. Addition of other PythonCAD interfaces will depend on the availability of a Python module for that particular interface and developer interest and action. The twenty-seventh release contains primarily bug fixes and internal code enhancements. A long-standing interface problem where the display of selected entities was not clear has been fixed. When you select an entity it is redrawn in a highlighting color, making it clear which entities are selected at any one time. Also, the ability to deselect a selected entity has been added to the interface. The bug fixes included in this release address a few problems introduced in the previous release as well as various older issues. A mailing list for the development and use of PythonCAD is available. Visit the following page for information about subscribing and viewing the mailing list archive: http://mail.python.org/mailman/listinfo/pythoncad Visit the PythonCAD web site for more information about what PythonCAD does and aims to be: http://www.pythoncad.org/ Come and join me in developing PythonCAD into a world class drafting program! Art Haas -- Man once surrendering his reason, has no remaining guard against absurdities the most monstrous, and like a ship without rudder, is the sport of every wind. -Thomas Jefferson to James Smith, 1822

Flightdeck-UI Library re-released under the LGPL
by George Belotsky 07 Dec '05

07 Dec '05

The goal of the Flightdeck-UI project is to apply ideas from aircraft instrumentation design to general purpose user interfaces. The Flightdeck-UI Tkinter library has been re-released under the GNU Lesser General Public License (LGPL). This is a standard, well-known license, recognized by both the FSF and the OSI. Previously, the Flightdeck-UI library was licensed under the Open Light Software Inc. Open License. Note that this change affects the library only; Flightdeck-UI Online and Flightdeck-UI MVM remain under the GPL license. Since MVM packages include the full library, however, there is also a new MVM release which includes the LGPL-licensed library code. The new library and MVM releases are both numbered 0.2.1. These are stable versions. See the homepage: "http://www.openlight.com/fdui" or go directly to the download page: "http://www.openlight.com/fdui/download.html". What is Flightdeck-UI --------------------- The goal of the Flightdeck-UI project is to apply ideas from aircraft instrumentation design to general purpose user interfaces. The web service version (Flightdeck-UI Online) retains the plug-in architecture of previous releases. Each plugin, however, may now be monitored at different sampling rates. Multiple data sources (hosts on the Internet, embedded devices, etc.) can be tracked simultaneously. Also, virtually any Unix command that you enter from the shell can be automatically executed by Flightdeck-UI Online, and the results displayed by the system's virtual instruments. Although the web service requires a Flash front end (developed using only the MTASC open source ActionScript compiler; see http://www.mtasc.org/) Flightdeck-UI Online is still primarily written in Python. The author welcomes any ideas and suggestions: please email them directly to "python(a)openlight.com". Best Wishes, George Belotsky.
