HTSQL 2.1-RC1 : A Query Language for the Accidental Programmer
by Clark C. Evans 15 Dec '11

15 Dec '11

We'd like to announce the release candidate for HTSQL 2.1, a high-level query language and web service gateway for relational databases. HTSQL is specifically designed for analytical inquiries and targeted to data analysts and web developers. HTSQL is implemented as a WSGI component, works with PostgreSQL, MySQL, SQLite and could be used to embed ad-hoc reporting features into your Python application. Homepage: http://htsql.org Download: http://pypi.python.org/pypi/HTSQL/ Source: http://bitbucket.org/prometheus/htsql Since 2.0 release, announced in February, we added many new language features which increase the "query power" of the language. HTSQL is now able to express quite sophisticated business inquiries. The 2.2 release of HTSQL later this year will be focused on "usability". It'll include improved configuration, a query editor and formatting options. Also for this release we've cleaned up the homepage for HTRAF -- a javascript toolkit for constructing attractive dashboards and interactive reports. This toolkit is MIT licensed and implemented as a JQuery plugin. For more detail, please visit http://htraf.org. Let's us know if you have any questions! Clark C. Evans & Kirill Simonov *********************************************************** HTSQL -- A Query Language for the Accidental Programmer *********************************************************** HTSQL ("Hyper Text Structured Query Language") is a high-level query language for relational databases. The target audience for HTSQL is the accidental programmer -- one who is not a SQL expert, yet needs a usable, comprehensive query tool for data access and reporting. HTSQL is also a web service which takes a request via HTTP, translates it into a SQL query, executes the query against a relational database, and returns the results in a format requested by the user agent (JSON, CSV, HTML, etc.). Use of HTSQL with open source databases (PostgreSQL, MySQL, SQLite) is royalty free under BSD-style conditions. Use of HTSQL with proprietary database systems (Oracle, Microsoft SQL) requires a commercial license. See ``LICENSE`` for details. For installation instructions, see ``INSTALL``. For list of new features in this release, see ``NEWS``. HTSQL documentation is in the ``doc`` directory. http://htsql.org/ The HTSQL homepage http://htsql.org/doc/introduction.html Get taste of HTSQL http://htsql.org/doc/tutorial.html The HTSQL tutorial http://bitbucket.org/prometheus/htsql HTSQL source code irc://irc.freenode.net#htsql IRC chat in #htsql on freenode http://lists.htsql.org/mailman/listinfo/htsql-users The mailing list for users of HTSQL HTSQL is copyright by Prometheus Research, LLC. HTSQL is written by Clark C. Evans <cce(a)clarkevans.com> and Kirill Simonov <xi(a)resolvent.net>. Generous support for HTSQL was provided by the Simons Foundation.

ANN : Karrigell-4.3.6 released
by Pierre Quentel 31 Oct '11

31 Oct '11

Hi, A new version of the Karrigell web framework for Python 3.2+ has just been released on http://code.google.com/p/karrigell/ One of the oldest Python web frameworks (the first version was released back in 2002), it now has 2 main versions, one for Python 2 and another one for Python 3. The Python 2.x version is available at http://karrigell.sf.net ; this branch is maintained, but no new feature is going to be developed All the development work is now focused on the version for Python 3. The first release was published in February and we are already at the 10th release Karrigell's design is about simplicity for the programmer and integration of all the web environment in the scripts namespace. For instance, the "Hello world" script requires 2 lines : def index(): return "Hello world" All the HTML tags are available as classes in the scripts namespace : def index(): return HTML(BODY("Hello world")) To build an HTML document as a tree, the HTML tags objects support the operators + (add brother) and <= (add child) : def index(): form = FORM(action="insert",method="post") form <= INPUT(name="foo")+BR()+INPUT(name="bar") form <= INPUT(Type="submit",value="Ok") return HTML(BODY(form)) The scripts can be served by a built-in web server, or through the Apache server, either on CGI mode or using the WSGI interface The package obvioulsy has built-in support for usual features such as cookie and session management, localization, user login/logout/role management. It also includes a complete documentation, with tutorial and a set of how-to's A helpful and friendly community welcomes users at http://groups.google.com/group/karrigell Enjoy ! Pierre
