System Browser - POC

A simple python browser to add custom functions and variables to Javascript.

There is an instance of a custom class Commands that is added to JavaScript global context. This way is possible to call an operating system command from frontend.

Class functionalities: - showMessage(string): Method to call a message box with a custom string; - whoami: Attribute with operational system username; - version: Attribute with Python version.

# The line below describes how custom object it will be called on JavaScript, in this case: Python
webView.page().mainFrame().addToJavaScriptWindowObject("Python", custom)

How to start it

chmod +x browser
./browser

How to use these custom functionalities

// Send a message
Python.showMessage("Foo");

// Get attrbiutes
alert(Python.version);
alert(Python.whoami);

Take index.html as an example.

Conclusion

Using this concept, is possible to call an operating system functionality, communicate with an hardware (eg: usb ports, serials,...) or anything is backend based (local only :P) just using a JavaScript call.
