ANN: PyQt v3.16 Released
by Phil Thompson 25 Mar '06

25 Mar '06

Riverbank Computing is pleased to announce the release of PyQt v3.16 available from http://www.riverbankcomputing.co.uk/pyqt/. The main benefit of this release is that it can be installed side by side with the soon-to-be-released PyQt v4 (for Qt v4). Other changes since the last release include: - improved interoperability between QString and Python's string and unicode objects. PyQt is a comprehensive set of Qt bindings for the Python programming language and supports the same platforms as Qt. Like Qt, PyQt is available under the GPL (for UNIX, Linux and MacOS/X), a commercial license (for Windows, UNIX, Linux and MacOS/X) and a free educational license (for Windows). PyQt is implemented as a set of 9 extension modules containing 300 classes and over 5,750 functions and methods. PyQt also includes bindings to QScintilla, the port to Qt of the Scintilla editor component. PyQt can be used either as a rapid prototyping tool, or as an alternative to C++ for developing large Qt applications. PyQt includes the pyuic utility which generates Python code to implement user interfaces created with Qt Designer in the same way that the uic utility generates C++ code. Third party tools are also available - such as eric3, a comprehensive IDE (including an editor, debugger, class browser, integration with Qt Designer, re-factoring tools, unit testing tools and integration with source code control systems). eric3 is written entirely using PyQt and is available from http://www.die-offenbachs.de/detlev/eric3.html.

ANNOUNCE: twill 0.8.4
by Titus Brown 23 Mar '06

23 Mar '06

ANNOUNCING twill v0.8.4. 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 ninth public release of twill, version 0.8.4. You can install twill with easy_install, or download this release at http://darcs.idyll.org/~t/projects/twill-0.8.4.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. --- Significant changes with 0.8.4: * improved installation docs and simplified installation; * added link checking, requirements processing, and arguments parsing extension modules. * improved extension module handling; added extension module documentation. * fixed memory leaks. * fixed tidy problem on Windows. * line number of scripts printed on traceback. * fixed file:// URLs. * added option for debugging HTTP-EQUIV REFRESH code.

An Efficient Scalar Class in Python
by uymqlp502＠sneakemail.com 23 Mar '06

23 Mar '06

My previous announcement on this was only nine days ago, but in retrospect I think that release was premature. I have made substantial simplifications and improvements since then. Here is the abstract from the three-page user guide (which is in PDF): A Python class was designed to represent physical scalars and to eliminate errors involving implied physical units (e.g., confusing angular degrees and radians). The standard arithmetic operators are overloaded to provide syntax identical to that for built-in numerical types. The scalar class allows the user to easily define a set of appropriate physical units for any particular application or domain. Once an application has been developed and tested, the units can easily be switched off, if desired, to achieve the execution efficiency of operations on built-in numerical types (which can be two orders of magnitude faster). The scalar class can also be used for discrete units to enforce type checking of integer counts, thereby enhancing the built-in dynamic type checking of Python. Give it a try. If you do scientific or engineering computation, I bet you'll like it! http://RussP.org/scalar.htm

ANN: ClientForm 0.2.2 released
by John J Lee 22 Mar '06

22 Mar '06

http://wwwsearch.sourceforge.net/ClientForm/ This is the first stable release of ClientForm 0.2. (See below for the list of changes since 0.2.1b.) Many improvements have been made as part of the 0.2 release, thanks largely to Gary Poster, Benji York and their employer Zope Corporation as part of their work on zope.testbrowser. These include: * 0.1 backwards compatibility mode (backwards_compat switch). * Greatly improved support for labels, including control labels. * Added first-class support for list items and labels. * A few methods have been added, and many superfluous methods deprecated. * The example script on the web page / README.html is now an executable script in the examples directory, that runs against a test page on the wwwsearch.sourceforge.net site. * Label matching is now by substring (after compression of whitespace), not by exact string equality. * Support for list item ids. * Finding controls or items now raises AmbiguityError if no nr argument is supplied and the other arguments do not uniquely identify the control or item. The old behaviour is restored by passing nr=0. * Fix multiple identical list item behaviour. * Fixed a bug where disabled list items were successful (got sent back to the server). * More intuitive disabled list item behaviour. * Large sections of the module have been reimplemented using classes Item and Label, making for better code. * Added ListControl.get(), ListControl.get_items(), HTMLForm.set_value_by_label(), and HTMLForm.get_value_by_label() methods. * Applied patch from Titus Brown to add .clear() method to all Controls. * The following ListControl methods have been deprecated: possible_items get_item_attrs set_item_disabled get_item_disabled set_single toggle_single set toggle * The following HTMLForm methods have been deprecated: possible_items set_single toggle_single set toggle * The by_label argument of the following methods has been deprecated: get_value set_value * Added support for setuptools / EasyInstall / Python Eggs. * Make entitydefs more sane. Expose entitydefs in ParseFile / ParseResponse functions. Changes since 0.2.1b: * Fixes to setup.py &c. * Follow IE and Firefox on algorithm for choosing MIME boundary -- servers are buggy on this. * Fix POST multipart/form-data parameter ordering (patch from Balazs Ree) and ImageControl ordering. * Fix .fixup() of disabled select with no selected options (John Wayne). * Encoding fixes. * Add BeautifulSoup support (not yet well tested). * Switch from htmllib to sgmllib. * Add form name to str(HTMLForm). * Make parser debugging a bit easier. Requires Python 2.0 or newer. ClientForm is a Python module for handling HTML forms on the client side, useful for parsing HTML forms, filling them in and returning the completed forms to the server. It developed from a port of Gisle Aas' Perl module HTML::Form, from the libwww-perl library, but the interface is not the same. Simple example: from urllib2 import urlopen from ClientForm import ParseResponse forms = ParseResponse(urlopen("http://www.example.com/form.html"), backwards_compat=False) form = forms[0] print form form["author"] = "Gisle Aas" # form.click() returns a urllib2.Request object # (see HTMLForm.click.__doc__ if you don't have urllib2) response = urlopen(form.click("Thanks")) John

ANN: SCSIPYTHON added to Sourceforge
by sam 22 Mar '06

22 Mar '06

I have updated and moved my SCSI diagnostic tools from starship to sourceforge. I will be still maintaining these files at both locations as long as starship exists. These tools allow low level tests to be conducted on storage devices under the Windows operating system. These routines access all storage devices through the Windows SCSIPASSTHROUGH layer, which maps all storage devices (SCSI,IDE/ATA,USB,PCMCIA,DVD,CD) to look like a SCSI device that is accessed using SCSI command descripter blocks. The move to Sourceforge also places the sourcecode,and files under CVS control.
