ANN: Pocoo (bulletin board software) 0.1 beta released

by Georg Brandl

We're pleased to announce that Pocoo 0.1 (beta) was released today (Sept. 10, 2006). Pocoo <http://www.pocoo.org/> is a bulletin board software (aka. message board) written in Python, adhering to the WSGI standard. In the long term, it is meant to compete with systems like phpBB. It provides an advanced plugin system with a component architecture which allows other developers to modify Pocoo to their liking without the need to touch existing source code. Building upon SQLAlchemy, Pocoo is able to use either MySQL, SQLite, Oracle or Postgres as the storage backend. The 0.1 release is not meant to be feature complete. It's more like a preview to show off what's already there. If you like the idea, *feel free to join us!* Features ^^^^^^^^ Currently implemented: * Support for either flat or threaded post view * URLs are very readable, furthermore one URL works for both flat and threaded view * Support for JSONRPC and XmlHTTPRequest to dynamically fetch data where useful while having a fallback for non-JS users * Very powerful plugin system * Extensible authentication system * WSGI compliancy * Database support for MySQL, Sqlite, Postgres, Oracle * BBCode/rst/safehtml parsers for markup * Javascript editors for the markup * Avatar support * User profiles and settings Planned features ... can be found in the Idea Pool at http://trac.pocoo.org/wiki/IdeaPool. Download ^^^^^^^^ Download the release at <http://www.pocoo.org/download>. Cheers, Georg Brandl, on behalf of the Pocoo Team

Myghty 1.1 Released

by Michael Bayer

Myghty 1.1 Released Myghty is a Python Server Page templating framework designed for large-scale, high availability websites and applications. Its conceptual design and template syntax is derived from HTML::Mason, the popular Perl-based web application platform used by Amazon.com, del.icio.us, Bricolage and others. Myghty serves as an excellent platform for developers to create custom web applications; it is the framework from which the Pylons (http://www.pylonshq.com) WSGI framework first evolved, and remains the primary template and caching engine used by Pylons. The MyghtyUtils container system, which powers Myghty's caching and session support, is used by Pylons, Turbogears, and others. Myghty is also used by itself as the web framework powering Bittorrent's website at http://www.bittorrent.com, a top- ranked and extremely high traffic website. Since its original release, Myghty has introduced many new concepts and features not found in Mason, including a rudimentary MVC framework, WSGI support, threading support and an open-ended rule-based URL resolution system. It receives favorable reviews for its ease of use, small footprint, quick and smooth operation, and great flexibility. It offers full Python scripting support within templates including a unique system of intermingling significant-whitespace-sensitive Python code with ordinary markup. Myghty also includes syntaxes that allow fine-grained control of whitespace, which makes it one of the best templating systems not just for HTML and markup but also for email generation and other whitespace-sensitive text formats. Myghty is easy to use within many popular web frameworks, including directly in any CherryPy or Turbogears application via the Buffet template adapter plugin, originally written for Myghty. Version 1.1 introduces a refactoring of Myghty's buffering and encoding internals to provide comprehensive support for Unicode and any character encoding combination - that is, full control over both the encoding of template files as well as the encoding of request output, including component- and programmatic configuration of encoding error handling. Myghty is released under the MIT License. Documentation, examples and download links can be found at: http://www.myghty.org Michael Bayer mike(a)myghty.org <P><A HREF="http://www.myghty.org">Myghty 1.1</A> - A high performance Python Server Page templating framework derived from HTML::Mason.

ANN: PLY-2.0 (Python Lex Yacc)

by David Beazley

September 8, 2006 Announcing : PLY-2.0 (Python Lex-Yacc) http://www.dabeaz.com/ply I'm pleased to announce a significant new update to PLY---a 100% Python implementation of the common parsing tools lex and yacc. PLY-2.0 features a completely new implementation of LALR(1) parsing that provides a significant speedup when generating the underlying parsing tables. This new implementation also (hopefully) fixes all outstanding bugs in LALR (1) parsing that were reported for previous versions of PLY-1.x. Here are a few PLY highlights: - PLY is closely modeled after traditional lex/yacc. If you know how to use these or similar tools in other languages, you will find PLY to be comparable. - PLY provides very extensive error reporting and diagnostic information to assist in parser construction. The original implementation was developed for instructional purposes. As a result, the system tries to identify the most common types of errors made by novice users. - PLY provides full support for empty productions, error recovery, precedence rules, and moderately ambiguous grammars. - Parsing is based on LR-parsing which is fast, memory efficient, better suited to large grammars, and which has a number of nice properties when dealing with syntax errors and other parsing problems. Currently, PLY can build its parsing tables using either SLR or LALR(1) algorithms. - PLY can be used to build parsers for large programming languages. Although it is not ultra-fast due to its Python implementation, PLY can be used to parse grammars consisting of several hundred rules (as might be found for a language like C). The lexer and LR parser are also reasonably efficient when parsing normal sized programs. More information about PLY can be obtained on the PLY webpage at: http://www.dabeaz.com/ply PLY is freely available and is licensed under the terms of the Lesser GNU Public License (LGPL).

TurboGears 1.0b1 released!

by Kevin Dangoor

I am pleased to announce TurboGears 1.0b1, which now supersedes the 0.8.9 release as the preferred TurboGears release. Many people have been using the TurboGears 0.9x releases for several months now and have been very happy with the results. The 1.0 APIs are stable and we're focused on bugs and docs for the final 1.0 release. This is a bugfix release over 0.9a9. What is TurboGears? ------------------- TurboGears is a popular rapid web development megaframework, built from a number of great Python projects and with a bunch of high-level features built within the TurboGears project. TurboGears is a front-to-back framework helping you on the front end (the MochiKit JavaScript library), templates for the view (Kid), the controller in the middle (based on CherryPy) and an object-relational mapper for your database (SQLObject). To that mix of projects, TG adds: * Widgets: Python objects that bundle JavaScript, CSS, HTML and server-side validation to make form creation and powerful JavaScript features easy. * Internationalization: Tools and APIs to help you localize the strings in your application. * Identity: Authentication and authorization made easy * Toolbox: a web-based GUI to help you work on your project (write your own as well!) Includes CatWalk to help you work with your database data and Model Designer to help you design your database graphically. * tg-admin: command line tool that gives you a quick start to your project, helps you set up your database and more! * Easy Ajax: flexible template support allows you to choose a different template engine (output HTML, JSON, plain text, etc. all from one method) * Built-in database transactions: keeps your database (and you!) sane. Transactions are committed or rolled back based on the success or failure of your controller code. * flexibility as needed: though Kid and SQLObject are the standards, we already support many other template engines (Cheetah, Markup, Django) and the powerful SQLAlchemy object-relational mapper. * community: last but definitely not least -- more than 2,000 users on the main mailing list, and others on non-English mailing lists In short, there are lots of tools to help you get the job done quickly. What's New Since 0.8 -------------------- Nearly everything. All of the projects that TG uses have had significant upgrades, and nearly all of the features that have been built by TurboGears contributors are new.

itools 0.14.2 released

by "J. David Ibáñez"

itools is a Python library, it groups a number of packages into a single meta-package for easier development and deployment: itools.catalog itools.http itools.uri itools.cms itools.i18n itools.vfs itools.csv itools.ical itools.web itools.datatypes itools.rss itools.workflow itools.gettext itools.schemas itools.xhtml itools.handlers itools.stl itools.xliff itools.html itools.tmx itools.xml This release brings user interface improvements and many bug fixes. These are the most important changes: itools.catalog -- Fix keyword fields that are indexed but not stored, when there is at least one value that contains spaces. The format of the catalog changes a little so it must be rebuilt. itools.cms -- The HTML/CSS code for the tabs has been updated to work better in different browsers, now it even looks nice in text mode (#382). The web interface for calendar objects has seen various improvements (#82, #496). The configuration file and the "icms-init" script accept a new option, "smtp-host", which defines the host to use to send emails. A bunch of minor bugs have been fixed in itools.cms, including #306, #308, #458, #459, #460, #497, #498, #500 and #501. itools.csv -- The CSV parser has been separated from the CSV handler, so it can be used independently ("from itools.csv import parser"). Fixed a serious bug which prevented to create CSV handlers from scratch. itools.gettext -- Now the PO handler properly detects the charset defined in the PO files header. The family of igettext scripts has been updated to use the new API of itools 0.14. itools.xhtml -- Now the "title" attribute of (X)HTML documents is always extracted to be translated, not only in "img" elements. Fix corner case in the automatic translation code. Declare some elements as inline to improve the behaviour of the translation machinery. Credits: - Hervé Cauwelier improved the web interface of itools.cms; - Nicolas Deram updated the calendar code; - J. David Ibáñez fixed many bugs; - Josef Meile found the problem in the PO handler.

[pygtk] ANNOUNCE: PyGTK 2.10.0

by Johan Dahlin

I am pleased to announce version 2.10.0 of the Python bindings for GTK. The new release is available from ftp.gnome.org and its mirrors as soon as its synced correctly: http://ftp.gnome.org/pub/GNOME/sources/pygtk/2.10/ This is an unstable release and should be used with caution. Blurb: GTK is a toolkit for developing graphical applications that run on systems such as Linux, Windows and MacOS X. It provides a comprehensive set of GUI widgets, can display Unicode bidi text. It links into the Gnome Accessibility Framework through the ATK library. PyGTK provides a convenient wrapper for the GTK+ library for use in Python programs, and takes care of many of the boring details such as managing memory and type casting. When combined with PyORBit and gnome-python, it can be used to write full featured Gnome applications. Like the GTK+ library itself PyGTK is licensed under the GNU LGPL, so is suitable for use in both free software and proprietary applications. It is already in use in many applications ranging from small single purpose scripts up to large full features applications. What's new since 2.9.6? - Issue a warning when a DISPLAY is not set (#316877, Johan, Jeremey Katz) - Copy style.css from pygobject docs when installing docs. (#351385 Gian Mario Tagliaretti) - Include the built docs in the tarball (Johan) PyGTK requires GTK+ >= 2.8.0 and Python >= 2.3.5 to build. GTK+ 2.10.0 is required for 2.10 API. Bug reports, as always, should go to Bugzilla; check out http://pygtk.org/developer.html and http://pygtk.org/feedback.html for links to posting and querying bug reports for PyGTK. What's new in 2.10.0? * Includes John Finlays reference manual * gobject bindings were removed, moved to a separate tarball * Added GTK+ 2.10 API: Assistant, CellRendererSpin, LinkButton, Printing*, RecentChooser, StatusIcon * Many code generator improvements * New module gtk.unixprint * Reduced memory usage * MacOS X support * Many bug fixes See NEWS for a complete list of changes Acknowledgements: Thanks to everybody who helped making this release possible: Wander Boessenkool, Wouter Bolsterlee, Ross Burton,Marco Cabizza Ben Caradoc-Davies, Gustavo J.
