ANN: lwebstring 0.5
by L. C. Rees 07 Oct '06

07 Oct '06

lwebstring is a lxml-based implementation of webstring, an XML template engine where Python is the template language. lxml exposes the power of the libxml2 and libxslt libraries to the Python programmer using the elegant and powerful yet simple ElementTree API. lwebstring extends this power to easy XML and HTML templating using the highly Pythonic webstring API inspired by PyMeld. lwebstring can be downloaded from its Python CheeseShop page at: http://cheeseshop.python.org/pypi/lwebstring/ or installed using setuptools' easy_install: easy_install lwebstring More information on lwebstring including documentation and an introductory tutorial can be found at: http://psilib.sourceforge.net/webstring.html Highlights of 0.5 include: - Support for including external XML files in an XML document using XInclude. This is useful for reusing common features between XML templates. - Function decorators for WSGI templating. This allows XML and HTML templating to be just another piece of WSGI middleware instead of using a separate API standard.

Templess 0.2 released
by Johnny deBris 07 Oct '06

07 Oct '06

Hi! I wanted to let you guys know that I've just released version 0.2 of my 'Templess' library. Templess is an extremely simple XML (attribute) based XML templating system. Since it doesn't allow any logic inside the template, it's relatively friendly to programmers: XML templating with Templess quite resembles string interpolation, except that the dictionaries can contain list values (for repeating items) and XML nodes and such. Of course this isn't always the easiest way to deal with certain things, since even simple view-related logic has to be done in code (think 'odd' and 'even' table rows), but if you're a purist, don't trust your template designers to even touch code, or just hate having to fiddle about with restricted Python or domain-specific languages in your templates, Templess may suit your needs... The library is released under a BSD-style license. Most important changes since 0.1: * major cleanups and bugfixes * added 'not' directive * removed 'lxml' dependency in favour of a simple SAX-like solution(1) * speed improvements and more predictable behaviour (both related to the previous point) Downloads can be found here: http://johnnydebris.net/templess.txt or direct link to 0.2: http://johnnydebris.net/.files/templess-0.2.tar.gz For more information, see http://templess.johnnydebris.net/, or send me an email or whatnot... Cheers, Guido Wesdorp (1) Sorry, lxml guys... It's a great lib, but has rather heavy dependencies (libxml2, libxslt, pyrex)...

Roundup Issue Tracker release 1.2.1
by Richard Jones 07 Oct '06

07 Oct '06

I'm proud to release version 1.2.1 of Roundup. Bugs fixed in 1.2.1: - E-mail subject line prefix delimiter configuration was being ignored. - Password confirm field in user editing. New Features in 1.2.x: - supports Python 2.5, including the sqlite3 module - full timezone support (sf patch 1465296) - handle connection loss when responding to web requests - match incoming mail In-Reply-To against existing messages when no issue id is specified in the Subject - added StringHTMLProperty wrapped() method to wrap long lines in issue display - include the popcal in Date field editing and search fields by default - @required in forms may now specify properties of linked items (sf patch 1507093) - update for latest version of pysqlite (sf bug 1487098; patch 1534227) - update for latest version of psycopg2 (sf patch 1429391) - new "exporttables" command in roundup-admin (sf bug 1533791) - roundup-admin "export" may specify classes to exclude (sf bug 1533791) - sorting and grouping by multiple properties is now supported by the backends *and* the classic template. - sorting, grouping, and searching by transitive properties (e.g., messages.author.supervisor) is now supported in all backends - added filter_sql to SQL backends which takes an arbitrary SQL statement and returns a list of item ids There was also a lot of bugfixes - see the bundled CHANGES.txt file for the list. If you're upgrading from an older version of Roundup you *must* follow the "Software Upgrade" guidelines given in the maintenance documentation. Roundup requires python 2.3 or later for correct operation. To give Roundup a try, just download (see below), unpack and run:: roundup-demo Release info and download page: http://cheeseshop.python.org/pypi/roundup Source and documentation is available at the website: http://roundup.sourceforge.net/ Mailing lists - the place to ask questions: http://sourceforge.net/mail/?group_id=31577 About Roundup ============= Roundup is a simple-to-use and -install issue-tracking system with command-line, web and e-mail interfaces. It is based on the winning design from Ka-Ping Yee in the Software Carpentry "Track" design competition. Note: Ping is not responsible for this project. The contact for this project is richard(a)users.sourceforge.net. Roundup manages a number of issues (with flexible properties such as "description", "priority", and so on) and provides the ability to: (a) submit new issues, (b) find and edit existing issues, and (c) discuss issues with other participants. The system will facilitate communication among the participants by managing discussions and notifying interested parties when issues are edited. One of the major design goals for Roundup that it be simple to get going. Roundup is therefore usable "out of the box" with any python 2.3+ installation. It doesn't even need to be "installed" to be operational, though a disutils-based install script is provided. It comes with two issue tracker templates (a classic bug/feature tracker and a minimal skeleton) and five database back-ends (anydbm, sqlite, metakit, mysql and postgresql).

ANN: PAMIE web dev testing with Internet Explorer (2 New ShowMeDo.com Videos)
by Ian Ozsvald 04 Oct '06

04 Oct '06

Summary: Robert Marchetti has created two videos showing you how to use his PAMIE tool to interactively drive Internet Explorer for web development and testing: http://showmedo.com/videos/series?name=pythonMarchettiPamieSeries Detail: The first PAMIE video covers driving IE interactively (querying Google, check the html src, clicking a button, visiting the Python homepage as a result). The second video shows you how to configure PAMIE with an XML file to automatically form-fill a web page for testing. This video also shows nice usage of the ElementTree module. The videos are 9 minutes and 11 minutes respectively and should play on all platforms. About ShowMeDo.com: Free videos (we call them ShowMeDos) showing you how to do things. The videos are made by us and our users, for everyone. Over half of our content is for Python. We'd love to have more contributions - would you share what you know? The founders, Ian Ozsvald, Kyran Dale -- ian <at> showmedo.com http://www.showmedo.com
