Match 'n Dispatch

=================

Match python args and dispatch based on their contents.

Install

-------

```$ pip install mnd```

Getting started

---------------

Create a dispatcher

```python

from mnd.dispatch import Dispatcher, handle

>>> d = Dispatcher()

```

Add a handler with the handy decorator

```python

>>> @handler(d, msg="hello")

>>> def say(msg=None):

...     print "got message: ", msg

```

Try dispatching some events

```python

>>> d.dispatch(msg="gets filtered out...")

>>> d.dispatch(msg="hello")

got message: hello

```

Match attributes using rules

-----------------------------

As well as equality attributes can be matched using rules including,

the full list is ```in lt le eq ne ge gt```.

These are inspired by the django filter options.

Example using "in"

```python

>>> @handler(d, msg__in=["hello", "hi"])

>>> def greeting(msg=None):

...     print "greetings"

>>> d.dispatch(msg="hello")

greetings

>>> d.dispatch(msg="hi")

greetings

```

Example using "gt" and "le"

```python

from collections import namedtuple

Worm=namedtuple("Worm", "segments")

worm1=Worm(4)

worm2=Worm(90)

>>> @handler(d, dict(segments__le=50))

>>> def ordinary_handler(w):

...     print("ordinary worm with %s segment.s" % segments)

>>> @handler(d, dict(segments__gt=50))

>>> def long_handler(w):

...     print("long worm with %s segment.s" % segments)

>>> d.dispatch(worm1)

ordinary worm with 4 segments.

>>> d.dispatch(worm2)

long worm with 90 segments.

```

Unit Test

---------

```$ python setup.py test```
