// JSON Jinja // a server/client templating system

-- What is it?

 JSON Jinja is a templating language inspired by Jinja2 with the
 idea that a template should be able to operate on the same JSON
 data on the server and on the client with the same semantics.

 It follows largely the Jinja2 feature set but restricts and
 changes semantics to be better compilable to JavaScript and to
 better work on different execution environments.

 The end goal is to define the language so that it can be
 implemented in different languages without having to implement
 a whole virtual machine or something similar.

 This implementation however is written in Python based on my
 templatetk library and will generate JavaScript code for the
 client that can be run with a minimal runtime library.

-- Why?

 To be able to use the same JSON data to render a template both
 on the server and the client.  The idea is that you render
 the template on the server the first time the page is loaded
 and from that point onwards you only transmit JSON to the client
 and render on the clientside.

 If a browser does not have a proper history API or JavaScript
 one can continue to request new pages from the server and
 render them there.

-- Requirements?

 Currently Python 2.6 and templatetk from my github repo.
 templatetk and this library are both evolving at the moment.
