Whirlwind

A wrapper for tornado web to run easily web applications as plugins.

How to use it?

The simplest way to use Whirlwind is to instantiate the Application class along with plugins directory and run its instance with the run method.

import whirlwind.web

my_app = whirlwind.web.Application('data/plugins')
whirlwind.web.run(my_app)

How to write a plugin and manually import it?

In your plugins directory, create a directory with the plugin name, i.e. test_plugin in the following directories: lib, static and templates. The plugins directory should contain a similar structure:

Directory structure:

├── plugins/
│   ├── lib
│   │   ├── test_plugin
│   │   │   ├── __init__.py
│   │   │   ├── my_plugin.py
│   │   │   ├── plugin.json
│   ├── static
│   │   ├── test_plugin
│   │   │   ├── js
│   │   │   │   ├── some_javascript.js
│   ├── templates
│   │   ├── test_plugin
│   │   │   ├── my_html_template.html

The plugin.json file contains information on URI mapping to plugin classes.

{
    "modules" : ["test_plugin.my_plugin"],
    "handlers" : [
                 ["/someaction/", "test_plugin.my_plugin.MyActionHandler"],
                 ["/otheraction/(\w+)", "test_plugin.my_plugin.MyActionSecondHandler"],
                 ]
}

MyActionHandler and MyActionSecondHandler are classes that extend either tornado.web.RequestHandler or tornado.websocket.WebSocketHandler and all the documentation of these parent classes applies to them. You can find more information in the Tornado documentation
