Lissard 0.1 Release - Templating System
by tweekgeek 13 Dec '07

13 Dec '07

I'd like to announce the alpha release of Lissard -- a minimal python templating system (GPL) designed to be easy to learn, fast, and all together simple to extend. Lissard makes no attempt to complicate it's code base with powerful and generally over-specialized features or syntax enhancements, but offers what I hope many will find as a pleasant middle ground between mod_python's PSP and systems like Jinja and Mako. Full documentation and examples are provided. To download and learn more please visit the Lissard home at http://tweekedideas.com/lissard.html For more information, questions, or comments, feel free to contact me directly at jkassemi(a)gmail.com. Take it easy, James Kassemi

by Frank Niessink 12 Dec '07

12 Dec '07

Hi, Release 0.66.2 of Task Coach is a bug fix release to work around a bug in the TreeListCtrl widget that caused crashes. The TreeListCtrl widget is used by Task Coach for the task tree view. Hopefully this single fix addresses multiple bug reports that had to do with Task Coach crashing. If not, please let me know. What is Task Coach? Task Coach is a simple task manager that allows for hierarchical tasks, i.e. tasks in tasks. Task Coach is open source (GPL) and is developed using Python and wxPython. You can download Task Coach from: http://www.taskcoach.org In addition to the source distribution, packaged distributions are available for Windows XP/Vista, Mac OSX, and Linux (Debian and RPM format). Note that Task Coach is alpha software, meaning that it is wise to back up your task file regularly, and especially when upgrading to a new release. Cheers, Frank

ANN: pyparsing-1.4.10 released!
by Paul McGuire 11 Dec '07

11 Dec '07

I'm happy to announce that I have just uploaded the latest release (v1.4.10) of pyparsing. I had to quick turnaround this release because a bug I thought I had fixed in 1.4.9 still persisted. I now have unit tests to catch the problematic variations in the operatorPrecedence method. This release has a few new features and a few minor bug-fixes. Here are the notes for both 1.4.9 and 1.4.10: Version 1.4.10 - December 9, 2007 --------------------------------- - Fixed bug introduced in v1.4.8, parse actions were called for intermediate operator levels, not just the deepest matching operation level. Again, big thanks to Torsten Marek for helping isolate this problem! Version 1.4.9 - December 8, 2007 -------------------------------- - Added '*' multiplication operator support when creating grammars, accepting either an integer, or a two-integer tuple multiplier, as in: ipAddress = Word(nums) + ('.'+Word(nums))*3 usPhoneNumber = Word(nums) + ('-'+Word(nums))*(1,2) If multiplying by a tuple, the two integer values represent min and max multiples. Suggested by Vincent of eToy.com, great idea, Vincent! - Added pop() method to ParseResults. If pop is called with an integer or with no arguments, it will use list semantics and update the ParseResults' list of tokens. If pop is called with a non-integer (a string, for instance), then it will use dict semantics and update the ParseResults' internal dict. Suggested by Donn Ingle, thanks Donn! - Fixed bug in nestedExpr, original version was overly greedy! Thanks to Michael Ramirez for raising this issue. - Fixed internal bug in ParseResults - when an item was deleted, the key indices were not updated. Thanks to Tim Mitchell for posting a bugfix patch to the SF bug tracking system! - Fixed internal bug in operatorPrecedence - when the results of a right-associative term were sent to a parse action, the wrong tokens were sent. Reported by Torsten Marek, nice job! - Fixed quoted string built-ins to accept '\xHH' hex characters within the string. Download pyparsing 1.4.10 at http://sourceforge.net/projects/pyparsing/. The pyparsing Wiki is at http://pyparsing.wikispaces.com -- Paul ======================================== Pyparsing is a pure-Python class library for quickly developing recursive-descent parsers. Parser grammars are assembled directly in the calling Python code, using classes such as Literal, Word, OneOrMore, Optional, etc., combined with operators '+', '|', and '^' for And, MatchFirst, and Or. No separate code-generation or external files are required. Pyparsing can be used in many cases in place of regular expressions, with shorter learning curve and greater readability and maintainability. Pyparsing comes with a number of parsing examples, including: - "Hello, World!" (English, Korean, Greek, and Spanish(new)) - chemical formulas - configuration file parser - web page URL extractor - 5-function arithmetic expression parser - subset of CORBA IDL - chess portable game notation - simple SQL parser - Mozilla calendar file parser - EBNF parser/compiler - Python value string parser (lists, dicts, tuples, with nesting) (safe alternative to eval) - HTML tag stripper - S-expression parser - macro substitution preprocessor
