Jigna is a bridge between Traits and the HTML world to provide a UI toolkit for traits models that is based on the powerful technologies of HTML, CSS and Javascript. It provides two-way data bindings between the traits model and the HTML interface i.e. traits notifications automatically update the HTML UI and user inputs on the UI seamlessly change model attributes in Python. Jigna uses AngularJS for data bindings and one could think of it as an equivalent of AngularJS where the model lives in Python instead of Javascript. This gives us the power of Python and Traits for easily writing the application logic and the flexibility and expressibility of HTML for the user interface.

The HTML UI can be displayed both in the same Python process as well as remotely, allowing us to view and manipulate a Traits-based-object from the web.

You will require the following packages:

• Traits.
• Pyface with a working Qt backend (either PySide or PyQt4).

For the web interface, you need:

• Tornado.

You can install this either via pip or the usual means:

python setup.py install
python setup.py develop

or:

pip install -r requirements.txt

If you have set ETS_TOOLKIT, remember to set it to qt4. There are several examples to play with in the examples directory.
