Announce: Parametric Solutions (parasol)
by Charlie Taylor 25 Jan '09

25 Jan '09

Parasol is a python framework in which mathematical models can be investigated parametrically. Parasol enables easy optimization, sensitivity study, and visualization. The math model can be as big or as small as desired. Output is generated in plain text, HTML, and native Microsoft Suite files (Excel, Word and PowerPoint). A problem is defined by input and output parameters. Results are presented in a manner that conveys insight into system trends and characteristics. The process of performing an analysis results in an ample assortment of graphs, charts, and images that display system sensitivities, variations, and characteristics. Barriers to creating these displays have been reduced to single commands in order to facilitate their use. Parasol has been designed to run under Microsoft Windows.

Evoque Templating v0.4 for Python 3.0
by Mario Ruggier 20 Jan '09

20 Jan '09

Pleased to announce release 0.4 of Evoque Templating -- the generic full-featured text template engine with state-of-the-art features such as: exclusively unicode, dynamic overlays, format-extensible automatic quoting, in-process sandbox, caching, small (992 SLOC), simple, fast, etc. See overview of features at: http://evoque.gizmojo.org/features/ Highlights of release 0.4: - Support for Python 3.0 The same Evoque code base now runs on Python 2.4, 2.5, 2.6 and 3.0 -- possibly making Evoque the first full-featured template engine available for Python 3.0. Behaviour is identical on all four Python versions. - Tighter lockdown of the in-process sandbox (restricted mode) Primarily by an elaborated runtime scan of all expressions that are passed for evaluation. For an overview of how Evoque implements the in- process sandbox see: http://evoque.gizmojo.org/usage/restricted/ -- and yes, you may interpret this as an open challenge and invitation to try and break[*] it , and, in the unlikely chance that you succeed, you may request anything you like as compensation, as long as it is beer ;-) - Revision of whitespace handling Notably, reworked the meaning of the slurpy_directives=True mode to be more what most people seem to expect. - Continued speed improvements More minor performance optimizations. Evoque is fast, and is a real contender for the dubious but gratifying honour of overall **fastest pure-python template engine**. Included in the distribution are 3 benchmarks -- you can see the measured results on OS X 10.5 for Python 2.6.1 (as there is not much to benchmark against on Python 3.0) at: http://evoque.gizmojo.org/benchmark/ The resulting numbers are a tribute to python's conceptual integrity -- that rewards a straightforward implementation of a simple design with... amazing performance. Full changelog at: http://evoque.gizmojo.org/changelog/ Cheers, Mario [*] for a quick and dirty script to run devious templates, see: http://groups.google.com/group/comp.lang.python/msg/f6f0dfd67609f370
