ANN: ConfigObj 4.0.0 Final and Pythonutils 0.2.3

by Fuzzyman

ConfigObj 4.0.0 final and Pythonutils 0.2.3 have just hit the streets. http://www.voidspace.org.uk/python/configobj.html http://www.voidspace.org.uk/python/pythonutils.html They are both pure Python modules - the source distributions include full documentation, which is also online. What's New ? ============ ConfigObj 4.0.0 final has two bugfixes. Using ``setdefault`` to create a new section would return a reference to the dictionary you passed in - not the new section. Also fixed a trivial bug in ``write`` (wouldn't have affected anyone). Pythonutils 0.2.3 is updated to include the ConfigObj 4.0.0 final and cgiutils 0.3.3 ConfigObj is now marked stable. (But caveat emptor :-) What is ConfigObj ? =================== ConfigObj is a simple but powerful config file reader and writer: an *ini file round tripper*. Its main feature is that it is very easy to use, with a straightforward programmer's interface and a simple syntax for config files. It has lots of other features though : * Nested sections (subsections), to any level * List values * Multiple line values * String interpolation (substitution) * Integrated with a powerful validation system - including automatic type checking/conversion - repeated sections - and allowing default values * All comments in the file are preserved * The order of keys/sections is preserved * No external dependencies What is Pythonutils ? ===================== The Voidspace Pythonutils package is a simple way of installing the Voidspace collection of modules. Several of the Voidspace Projects depend on these modules. They are also useful in their own right of course. They are primarily general utility modules that simplify common programming tasks in Python. These are currently : * ConfigObj - simple config file handling * validate - validation and type conversion system * listquote - string to list conversion * StandOut - simple logging and output control object * pathutils - for working with paths and files * cgiutils - cgi helpers (and functions for sending emails etc) * urlpath - functions for handling URLs * odict - Ordered Dictionary Class All the best, Fuzzyman http://www.voidspace.org.uk/python

IMDbPY 2.2 released

by alberanid＠libero.it

IMDbPY 2.2 is available (tgz, deb, rpm, exe) from: http://imdbpy.sourceforge.net/ IMDbPY is a Python package useful to retrieve and manage the data of the IMDb movie database about both movies and people. With this release it is possible to retrieve some new information, including "guest appearances" for TV series; a lot of bugs were fixed and the SQL data access system was heavily improved. Platform-independent and written in pure Python (and few C lines), it can retrieve data from both the IMDb's web server and a local copy of the whole database. IMDbPY package can be very easily used by programmers and developers to provide access to the IMDb's data to their programs. Some simple example scripts are included in the package; other IMDbPY-based programs are available from the home page. -- Davide Alberani <alberanid(a)libero.it> [PGP KeyID: 0x465BFD47] http://erlug.linux.it/~da/

NYLUG meeting: 10/26 The Python Object Model with Alex Martelli & Google (slight correction)

by Ron Guerin

(date and time inadvertently omitted last time. sorry!) The New York Linux User's Group invites you to a special presentation by Alex Martelli of Google, on the Python Object Model. This presentation will be held at P.J. Clarke's Sidecar, rather than our usual location, and Google is picking up the tab for an hour and a half of open bar and food. Additionally, if you're looking for a job as a Python developer, bring your resume. Please RSVP at http://rsvp.nylug.org to attend, as seating is limited. PS: You may wish to bring ID and a GPG fingerprint to sign keys. - Ron (announcement follows) The New York Linux User's Group Presents Alex Martelli - on - The Python Object Model Held at P.J. Clarke's Sidecar October 26, 2005 6:00pm-10:00pm 915 Third Avenue @ 55th Street - NY Python is a multi-paradigm programming language, but, out of the paradigms it supports, there is no doubt that OOP (Object Oriented Programming) is the paradigm that forms Python's core. If you have done any substantial programming with Python, you have, most likely, used some of its OOP features. But -- have you ever stopped to really think about those OOP features, the mechanisms that Python uses (and exposes!) to implement them, and how best to make use of the possibilities this state of things offers? This subject is generally known as the "Object Model" of a language. This talk stops a bit short of examining every level of Python's Object Model -- in particular, it does not get into metatypes (metaclasses) and similar levels of "Black Magic". Rather, the talk sticks to the most practically interesting aspects of Python's Object Model as seen from the point of view of a programmer using Python -- understanding exactly what's going on in all kind of everyday OOP-usage situation, what alternatives and trade-offs these mechanisms imply (for example, when should you use closures, and when should you use functors instead? when to inherit, and when to delegate instead?), and how Design Patterns play into the mix (Python subsumes and build-ins some classic DPs, and makes a few others irrelevant due to its highly dynamic typing, but other classic DPs yet remain extremely relevant and important for optimal day to day use of OOP in Python). About Alex Martelli ------------------- Alex Martelli is Uber Technical Lead at Google, in Production Software. He wrote Python in a Nutshell and co-edited the Python Cookbook, and is a member of the Python Software Foundation. Before joining Google, Martelli spent 8 years with IBM, 12 with think3 inc, and 3 as a Python freelance consultant, mostly for AB Strakt (Sweden). P. J.

IPlib 0.9

by alberanid＠libero.it

IPlib 0.9 can be downloaded from: http://erlug.linux.it/~da/soft/iplib/ IPlib is a Python module useful to convert amongst many different notations and to manage couples of address/netmask in the CIDR notation. Some example scripts ('ipconv', 'nmconv' and 'cidrinfo') are included. With this release, you can use the CIDR class to test if a CIDR net is entirely contained in another one. -- Davide Alberani <alberanid(a)libero.it> [PGP KeyID: 0x465BFD47] http://erlug.linux.it/~da/

ANN: TurboGears 0.8a1 front-to-back web development

by Kevin Dangoor

TurboGears 0.8a1 is available now! What's New ========== This is a brief summary. The complete information about what's new can be found here: http://www.turbogears.org/about/changelog.html * API improvements based on feedback and patches from the first public release. Seven people contributed patches to TurboGears directly, and there's been quite a bit going on in the other projects. * Easier production of XML output from controller methods * Static file directories are set up in new quickstarted projects * Updates to all of the main included projects * IPython is used as the shell, if IPython is available * Bonjour support on the Mac * New getting started guide, and command line tool and configuration references and a new site template by Sebastian Jansson. * Several bug fixes Introduction ============ TurboGears (http://www.turbogears.org) brings together four major pieces to create an easy to install, easy to use web megaframework. It covers everything from front end (MochiKit JavaScript for the browser, Kid for templates in Python) to the controllers (CherryPy) to the back end (SQLObject). The TurboGears project is focused on providing documentation and integration with these tools without losing touch with the communities that already exist around those tools. TurboGears is easy to use for a wide range of web applications. To get a quick idea of what TurboGears is like, take a look at the 20 Minute Wiki tutorial and screencast. The total screencast with brief intro and conclusion did take a little over 23 minutes, but it's close to 20 minutes :) 20 Minute Wiki: http://www.turbogears.org/docs/wiki20/index.html TurboGears site: http://www.turbogears.org/ A big thanks to Remi Delon, Ian Bicking, Bob Ippolito, Ryan Tomayko, Phillip Eby and the many other contributors who have provided all of these great tools. Thanks also to the TurboGears contributors! -- Kevin Dangoor Author of the Zesty News RSS newsreader email: kid(a)blazingthings.com company: http://www.BlazingThings.com blog: http://www.BlueSkyOnMars.com
