Slurpy is an RPC mechanism to call python methods from javascript and viceversa.
Install the package using pip
$ pip install slurpy
- Create a new Slurpy server instance. With slurpy you can call javascript methods from the python function using the slurpy.javascript object and using the python object from the javascript side.
import slurpy
import os
def sum(a,b):
// is possible to call a javascript method and pass a python
// callback on result
slurpy.javascript.js_sum(1, 2, callback=on_js_sum_response)
return a + b
def on_js_sum_response(value):
print "The js_sum return = %d" % value
s = slurpy.Slurpy()
s.register(os)
s.register(sum)
s.start()- Then integrate on your HTML document , defining the function to be called by the server.
<html>
<head>
<script type="text/javascript" src="http://localhost:51711/slurpy/js"></script>
<script type="text/javascript">
//method invoked by the python code
var js_sum = function(a, b) {
return a + b;
}
//wait for loaded event
python.on('loaded', function(evt) {
python.dirname('/etc/passwd', function(response) {
console.log("Directory name" + response);
});
//module invoke
python.os.getenv("HOME", function(response) {
console.log("Home variable " + response);
});
//module invoke
python.os.getuid(function(uid) {
console.log("Current UID " + uid);
});
//direct method invoke
python.sum(10, 1000, function(response) {
console.log("Sum result " + response);
});
});
</script>
</head>

Start the server
$ python your_slurpy_server.py
Starting from version 0.1.6 slurpy supports extension via Plugin.
* Available hooks: Work in progress.
* Example:
<html>
<head>
<script type="text/javascript" src="http://localhost:51711/slurpy/js"></script>
<script type="text/javascript">
//callback invoked by the python code
var js_sum = function(a, b) {
return a + b;
}
var plugin = new python.Plugin("Sniffer");
plugin.hooks = {
init: function() {
//does nothing
},
on_execute: function(message) {
console.log("Before execution " + message);
return message;
}
}
//plugin.disable()
plugin.activate();
python.on('ready', function(evt) {
python.dirname('/etc/passwd', function(response) {
console.log("Directory name" + response);
});
python.os.getenv("HOME", function(response) {
console.log("Home variable " + response);
});
python.os.getuid(function(uid) {
console.log("Current UID " + uid);
});
python.sum(10, 1000, function(response) {
console.log("Sum result " + response);
});
});
