I made a page refresh tool in Python that watches for filesystem events and refreshes a page in a browser every time an event is registered. The project was to scratch an itch I had: I was working on a PHP web application and had to keep refreshing the page manually to see the changes. The intended targets are web developers and designers, and is similar to Live.js, except that it watches more than just UI objects, so it can be used to work with any web application. Its made to be platform independent (to be tested..), and has a Websocket server and Google Chrome extension client (https://github.com/lchi/freshy-chrome-extension) at the moment.It's built using autobahn (http://www.tavendo.de/autobahn/install_python_package.html) and watchdog (http://pypi.python.org/pypi/watchdog).
Hope someone finds this useful, questions and comments (and forks!) greatly appreciated.
