Development:

I just switch from mod_python publisher to mod_wsgi. As I did not found the right Python framework for my needs, So I wrote wsgi middlewares from scratch. This way I have control on each nested layer while allowing reusing of middleware

Current middleware are: svg_app: define an svg application with user authentication collab: manage a collaborative editor (ace) update: manage application update with Github graph: manage SVG diagram parsing and rendering wsgi_cg: the wsgi application for ConnectedGraph

As each middleware may have some javascript code, the application runs with a set of javascript modules that must be called in fixed order. I did not succed well to make middleware order call independent nor a way to avoid javascript multi declaration mid1(mid2(mid3(app))) should behave like mid3(mid2(mid2(app))) Help on this is wellcome
