RE: [Zope] AJAX and Zope
By Zope objects I meant: You've got a page template for example, and you include such an AJAX enabled object, basically rendering an HTML fragment, and the resulting page will include the page template code + the fragment (similar to a macro call), but will also include the needed javascript code to handle the asynchronous communication. Then another thing would be something like a PythonScript object (so you define python code and return python structures) and get it rendered as javascript to be included in somepage for processing the data returned by an asynchronous XML-RPC call to Zope within the browser.

RE: [Zope] AJAX and Zope
Well, that's why I mentioned this in my initial mail: http://jtauber.com/blog/2006/05/23/primitive_python_version_of_gwt_working (the python to javascript translator part) Of course I know how to make some AJAX to in Zope for some specific application. But I wanted to know if some of the core Zope developers had ever thought about a more generic approach. For example I am sure that having this python to javascript translator and objects like PythonScripts that would have a javascript view is something that would make AJAX enabled pages development on Zope much easier (just a matter of including the JS library and then make some python code).

That is a macro call. There is no difference. It just that the macro includes the HTML needed to suck in the JS library you use. I have been working on a simple WSGI middleware filter that handles js library insertion pretty well, without complicated macros that assure that a javascript library gets included only once. It works by creating a WSGI environ variable for desired includes. Individual widgets ask a utility to register their need for a particular javascript or css resource into that environ variable. After Zope is finished generating the page, the middleware inserts the appropriate script and/or style tags into head before delivery to the client. The current implementation works in Zope 3. I have not experimented with Zope 2 on this, but it seems that with Zope 2's new WSGI-friendliness and Five, it is likely not too far from something usable in Zope 2. The Zope 3 implementation needs zope.paste and paste.deploy. The middleware app itself should work for anything WSGI. Code (Due credit: the Zope 3 infrastructure for this borrows heavily from zc.resourcelibrary) and instructions are at http://zif.hill-street.net/headincludes Development status: works for me.
