z3c.form 1.0.0 released!
by Stephan Richter 24 May '07

24 May '07

Hello everyone, Roger and I are proud to announce the first release of the new form and widget framework ``z3c.form``! After years of talking about it, months of thinking about it and many weeks of implementation, we have finally completed it. For the curious and impatient ... --------------------------------- To run the demos do the following:: $ svn co svn://svn.zope.org/repos/main/z3c.formdemo/trunk formdemo $ cd formdemo $ python bootstrap.py $ ./bin/buildout $ ./bin/demo fg Now you can access the demo under: http://localhost:8080/ Since this takes a while to build, you can read on while waiting for the demo to come up. :-) Goals of z3c.form ----------------- While taking the best of the older ``zope.app.form`` and ``zope.formlib`` packages, this new framework provides much more flexibility and hooks as are needed in daily development. For example, creating a simple form can look almost identical to ``zope.formlib``, but integrating sub-forms is much simpler. Another important issue for us was keeping up-to-date with today's latest Web developments, especially AJAX-features. It is an expressed goal of this framework to provide enough flexibility to fully support AJAX-driven forms and widgets. A secondary goal is to provide flexibility to allow experimentation with new ideas without interupting the entire framework. Many of the features are implemented as components allowing simple replacement as desired. State of the Code ----------------- We consider the code feature complete with some real-world user scenarios implemented. The framework has not been used in a production environment yet, but we will base all our future project on it and switch older projects to this framework as needed. z3c.form ~~~~~~~~ This is the main package implementing the framework. It is 100% tested in a multitude of text files; start by reading README.txt, which provides you with an overview and priorities the text files for you. Unit Tests: 478 Documentation: 193k in 24 text files Architecture Layout: form-graph.png, widget-graph.png z3c.formui ~~~~~~~~~~ This package contains some base templates for DIV- and TABLE-based form layouts. Both layout options are implemented in different layers, allowing you to chose either layout default by simply adding the layer to your skin. z3c.formdemo ~~~~~~~~~~~~ Here you will find some small demo sub-packages that demonstrate the framework as it is to be used: * Hello World Message A demo of adding, editing and displaying simple message objects. It demonstrates the simple usage of add, edit and display forms. It also adds another button to the edit form. * Widgets A simple form whose purpose is to demonstrate the completeness of the input widgets. All fields except Dict and Object have an input widget as demonstrated in the form. It also demonstrates how the content object retrieval can be customized in a form. * Calculator A simple calculator implemented as a form. The demo shows how to write different types of buttons, register handlers for those button types and hook in a custom action manager. * Wizard This simple, linear wizard demonstrates the sub-form capabilities of ``z3c.form``. Since these packages do not provide an object widget, this demostration also shows how this need can bebetter solved using sub-forms. * Table/Spreadsheet This little table allows you to add and edit a simple content component within a table. The table is rendered using the ```zc.table`` package demonstrating how the two packages can be used together. jquery.* ~~~~~~~~ The ``jquery`` namespace packages provide a first attempt to have AJAX-enabled forms. It is already possible to validate widget values and do some other form-unrelated UI goodies. The features within the ``jquery`` and form packages will soon be demonstrated in detail on the new www.zope.org website, which will also be available in code form as ``z3c.website``. So stay tuned! Installation ------------ All packages have been released in source and binary-egg format on PyPI and ``download.zope.org/distribution``. You can use setuptools to install them. Here is a list of all packages: * z3c.form * z3c.formui * z3c.formdemo * jquery.javascript * jquery.layer * jquery.widget Enjoy! Regards, Roger and Stephan

Infrae has striven to keep Silva 2.0 almost feature identical to Silva 1.6, while refactoring and rebuilding large parts of the system ‘under the hood’, using advances in Zope and Five infrastructure. This major reworking should especially help extension developers by expanding the set of tools available to them. Changes in Silva 2.0 * Major refactoring of Silva to work with Zope 2.10 and up. * The Silva Find extension has been included in the Silva core. Many thanks to all who contributed. See HISTORY.txt in the Silva core package for detailed information about changes in Silva 2.0. For developer changes, see doc/developer_changes. Also see the changes in components such as Silva Metadata, External Sources, etc. What is Silva? Silva is an enterprise-class CMS designed for large organizations that manage multiple or complex websites. Content is stored in clean and future-proof XML, independent of layout and presentation. Features include a multi-version workflow system, XSLT rendering support, content reuse in multiple publications, sophisticated access management, extensive import/export facilities, fine-grained templating, and hi-res image storage and manipulation.

The CMF provides the foundation for popular software packages such as Plone. It is intended to be easily customizable, in terms of both the types of content used and the policies and services it provides. Where do I get it? For release files, change logs, installation instructions and more please visit "http://www.zope.org/Products/CMF/CMF-1.6.4", http://www.zope.org/Products/CMF/CMF-1.6.4.

by eGenix Team: M.-A. Lemburg 10 May '07

10 May '07

________________________________________________________________________ ANNOUNCING eGenix.com mxODBC Database Interface Version 3.0.0 Our commercially supported Python extension providing ODBC database connectivity to Python applications on Windows and Unix platforms This announcement is also available on our web-site for online reading: http://www.egenix.com/company/news/eGenix-mxODBC-Distribution-3.0-GA.html ________________________________________________________________________ ABOUT The mxODBC Database Interface allows users to easily connect Python applications to just about any database on the market today - on both Windows and Unix platforms in a highly portable and convenient way. This makes mxODBC the ideal basis for writing cross-platform database programs and utilities in Python. mxODBC is included in the eGenix.com mxODBC Distribution for Python, a commercial part of the eGenix.com mx Extension Series, a collection of professional quality software tools which enhance Python's usability in many important areas such as ODBC database connectivity, fast text processing, date/time processing and web site programming. The package has proven its stability and usefulness in many mission critical applications and various commercial settings all around the world. * About Python: Python is an object-oriented Open Source programming language which runs on all modern platforms (http://www.python.org/) By integrating ease-of-use, clarity in coding, enterprise application connectivity and rapid application design, Python establishes an ideal programming platform for todays IT challenges. * About eGenix: eGenix is a consulting and software product company focused on providing professional quality services and products to Python users and developers (http://www.egenix.com/) ________________________________________________________________________ NEWS mxODBC 3.0 has received a large number of enhancements and supports more ODBC drivers than ever. Some highlights: * mxODBC has been ported to Python 2.5. * We've worked a lot on the Unicode support and made it more robust, especially on Unix platforms where the ODBC Unicode support has stabilized over the last few years. You can now issue commands using Unicode and exchange Unicode data with the database in various configurable ways. * We've also added a methods to give you more control of the connections and cursors as well as the .callproc() method for calling stored procedures that mxODBC 2.0 was missing. * Multiple result sets via the .nextset() are also supported, so working with stored procedures should be a lot easier now. * Another highlight is the added support for Python's datetime module types and the option to use strings for date/time processing (e.g. to be able to use timezones in timestamps if that's supported by the database). * Python's decimal module is now supported as well and it's possible to configure mxODBC to return Decimal types for numeric values. * mxODBC 3.0 received full 64-bit support, so that you can run mxODBC (and all other mx Extensions) on e.g. AMD64 platforms. * We've switched from the old distutils wininst installer to the new MSI installer for the Windows Python 2.5 build. This gives you a lot more options for automatic installs, including unattended installs. See http://www.python.org/download/releases/2.5/msi/ for details. Note that in order to avoid confusion, we've decided to rename the eGenix.com mx Commercial Distribution to eGenix.com mxODBC Distribution with this release. The commercial distribution has always only contained the mxODBC package, so this was an obvious step to clarify things for our users. As always we are providing pre-compiled versions of the package for Windows, Linux, Mac OS X, FreeBSD and Solaris as well as sources which allow you to install the package on all other supported platforms. ________________________________________________________________________ DOWNLOADS The download archives and instructions for installing the package can be found at: http://www.egenix.com/products/python/mxODBC/ IMPORTANT: In order to use the eGenix mx Commercial package you will first need to install the eGenix mx Base package which can be downloaded from here: http://www.egenix.com/products/python/mxBase/ ________________________________________________________________________ UPGRADING Please note that mxODBC 2.0 does not support Python 2.5 on 64-bit platforms due to the Py_ssize_t changes in the Python C API. You are encouraged to upgrade to the new mxODBC 3.0 release, if you plan to deploy on 64-bit platforms and use Python 2.5 as basis for your applications. ________________________________________________________________________ LICENSES & COSTS This release brings you all the new features and enhancements in mxODBC that were previously only available in through our mxODBC Zope Database Adapter. Like the Zope product, mxODBC now requires that you install a license in order to use it. You can request 30-day evaluation licenses by writing to sales(a)egenix.com, stating your name (or the name of the company) and the number of eval licenses that you need. We will then issue you licenses and send them to you by email. Please make sure that you can receive ZIP file attachments on the email you specify in the request, since the license files are send out as ZIP attachements. _______________________________________________________________________ SUPPORT Commercial support for these packages is available from eGenix.com.
