DocIndexer includes command-line utilities, Python index and search classes plus a Win32 COM server that can be used to integrate indexing and searching into application software. The current version has parser support for Microsoft Word, HTML, PDF and plain text documents. Runtime Requisites ------------------ Win32: None (compiled binary distribution). Linux: Python 2.5, PyLucene 2, antiword and poppler-utils.

lockfile 0.1 - platform-independent advisory locks for Python
by skip＠pobox.com 03 Nov '07

03 Nov '07

Python's distribution supports a few different ways to lock files. None are platform-independent though. A number of implementations of file locks are out there, but as an exploration of the possibilities I wrote the lockfile module. It offers these features: * A platform-independent API * Three classes implementing file locks - LinkFileLock - relies on atomic nature of the link(2) system call. - MkdirFileLock - relies on atomic nature of the mkdir(2) systemm call. - SQLiteFileLock - provides locks through a SQLite database. * Locking is done on a per-thread basis by default, though locking can be done on a per-process basis instead. * Context manager support. The module contains documentation in ReST format and a decent set of test cases written using doctest. Almost all the test cases are attached to the _FileLock base class, so other implementations (e.g., using different relational databases or object databases like ZODB) can be sure they satisfy the same constraints. The lockfile module is available from PyPI: http://pypi.python.org/pypi/lockfile/ I welcome feedback from anyone who gives it a whirl. The code is stored in a Mercurial repository on my laptop, so subject to occasional access problems when I'm on the train others are welcome to have access to the source code. If that's of interest to you, drop me a note. -- Skip Montanaro - skip(a)pobox.com - http://www.webfast.com/~skip/

[ANN] Leo 4.4.4 Final released
by Edward K Ream 02 Nov '07

02 Nov '07

Leo 4.4.4 Final is available at: http://sourceforge.net/project/showfiles.php?group_id=3458&package_id=29106 Leo is a text editor, data organizer, project manager and much more. See: http://webpages.charter.net/edreamleo/intro.html Leo 4.4.4 contains many important features originally planned for later releases. The highlights of Leo 4.4.4: ---------------------------- - The Great Graph Aha: simple scripts allow Leo outlines to represent arbitrary directed graphs. There is no need for a separate 'graph world'. The graphed.py plugin is a direct result of this Aha. The graphed.py plugin allows you to create general graphs from Leo outlines. - @menus trees in settings files create all of Leo's menus. It is now dead easy to make Leo's menus look the way you want. - @buttons trees in settings files create common @button nodes created in all Leo outlines. - @auto nodes eliminate sentinels in derived files, thereby allowing people to collaborate using Leo more easily. **Warning**: for now, please make backup copies of files imported with @auto. - New commands for resolving cvs conflicts. - A threading_colorizer plugin replaces the __jEdit_colorizer__ plugin. This plugin features much better performance and a new, elegant algorithm. - Leo is now compatible with jython. - Better support for icons in headlines. - Many bug fixes and other minor improvements.

I'm happy to report the release of the O'Reilly ShortCut, "Getting Started With Pyparsing." This 65-page e-book goes into detail on Pyparsing's design rationale, basic features, and a succession of applications. "Getting Started With Pyparsing" covers a range of samples, from an extended version of "Hello, World!" to a 100-line search engine. An index helps you quickly find descriptions and sample uses of the most common Pyparsing classes and methods. Several chapter excerpts are available online, including this chapter on the Zen of Pyparsing: http://preview.tinyurl.com/yp4v48 For more details, see O'Reilly's web page: http://www.oreilly.com/catalog/9780596514235/ Thanks, -- Paul McGuire (For those who have downloaded it, please add a review to the book download page.)
