for my Python application (Windows platform) to be standards compliant, I need to embbed Ecmascript(Javascript) interpreter - I need to execute plugins written in this language. Which engine is suitable for Python, I have found bunch of them. Any recomendations are welcome.
To be more specific, I think that plugins will be pretty simple, they will be used to manipulate my class-based datamodel, no special libraries dependencies ... therefore I prefer some rather simple solution ...

PyQt includes a Javascript interpreter. You can expose Python objects and properties as Javascript objects and properties.
Ecmascript (Jscript) is Active-Scripting compliant. With PyWin32, you can : - call JScript functions (with parameters) - define pieces of code (& run it)
Another way, is to drive Internet-Explorer (via COM). You can set the IE-Windows as invisible, and connect the motor of execution (of JScript). Then, you can : - call JScript functions, with parameters et return ; variables, but also array (<=> lists) - connect to JScripts's objects (for read/write) - write new functions in JScript - etc.

What standard are you hoping to comply with? I mean, what kind of a program is this? -- Tim Roberts, t...@probo.com Providenza & Boekelheide, Inc.
I think no. Because these tech use COM. And COM don't exist under xxnux. But: - look if XPCOM, or dBus) can help you - search with the word "MOZLAB", who work a solution (plugin) for drive Firefox, from an external software.

Thats for our speech recognition server - it should executed "tags" with Javascript code embbeded in some XML grammar format.
I personally does not like COM solution. I prefer some simple library but may be it is just a hope. I will look to PyQT library and to Mozilla scripting engine, but I think that this one can get unnecessarily difficult.

Have you looked at the module 'python-spidermonkey'? It apparently "allows for the implementation of Javascript classes, objects and functions in Python, as well as the evaluation and calling of Javascript scripts and functions".

I have looked at it. It seems to be not fully working version, but I have not check it properly because the project homepage says "windows version is forthcoming".
At this time I am considering using some command line interpreter (maybe jsdb, http://www.jsdb.org/, based on spidermonkey) Idea is to save script code to file and let it run by interpreter and then parse the results. Problem is that this approach has very limited access to variables and objects exposed to javascript (they needs to be serialized before script run, script cannot call python functions etc) and also retrieving results is not straigtforward.

How about using Jython and Rhino [http://www.mozilla.org/rhino/] ? Could be worth your while, if you could live with coding for an older version of the Python spec.
