Slurpy
======
Slurpy is an RPC mechanism to call python methods from javascript and viceversa.
Installation
------------
Install the package using pip
$ pip install slurpy
Basic usage
-----------
* 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.
```python
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.
```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);
});
});
```
* Start the server
$ python your_slurpy_server.py
Writing Plugins:
================
Starting from version 0.1.6 slurpy supports extension via Plugin.
* Available hooks: Work in progress.
* Example:
``` 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);
});
});
```
