Generic scratch connector

This scratch connector, using scratchpy libraries, and its two lines of code are a binding to use with chrome extension "ExternalExec", so you can build web applications that send data to scratch.

Basically, you install ExternalExec, and, in your web app, you do this:

function updateSensor(name, vale){
    var evt = document.createEvent("CustomEvent");
    evt.initCustomEvent(
        "execute",
        true,
        true,
        {
            'command':'/usr/bin/python',
            'args': "<path_to_this_folder>/ScratchGenericSensor.py "
            + name + " " + value
        }
    );
    document.dispatchEvent(evt);
}

This code will provide an "updateSensor" function, wich, by passing name and value, will

WebAppScratch

Ok guys, I'll give you everything already done.

Just include scratchSensors.js in your web app, initialize it with the path to scratchGenercSensor, make the user running scratch to install and the extension and there you have it!

ScratchSensors.setup('<path_to_this_folder>/ScratchGenericSensor.py');
ScratchSensors.update('foo', 'bar');
ScratchSensors.update('bar', 'baz');

It uses localStorage, so, if you do the setup once, you wont be needing to do it anymore, never.

¡Imagine the posibilities!

Detailed install instructions

First, remember to recursively checkout the git.

git submodule init
git submodule update --recursive

Ok, now let's begin. We'll need the chrome extension installed, install it by dragging the CRX now present in Connector/ExternalExec/ExternalExec.crx into your extensions page. (Tip: To open your extensions page quickly use "chrome://extensions" in your navigation bar).

Now, source src/ScratchSensors.js in your application, and specify the location of Connector/ScratchGenericSensor.py.

Oh, you also have to activate remote sensors on scratch, but, for that, better use the scratch wiki.

Voilá, you got it, easy?

BTW, I know, using an external program and an extension wasn't the best way, but I had done the other extension (a few hours ago) for other stuffs, so... I figured I could use it here and buy myself some spare time ;-)
