bottle-hotqueue 0.2.0

FIFO Queue for Bottle built upon HotQueue

# bottlehotqueue

_FIFO message queue_ plugin for _bottle.py_ based on _HotQueue_

_[bottle.py](http://bottlepy.org) is a fast and simple micro-framework for python web-applications._

_[HotQueue](http://richardhenry.github.com/hotqueue/) is a Python library that allows you to use Redis as a message queue within your Python programs._

## Installation

$ pip install bottle-hotqueue

### From source:

$ python setup.py install

### Dependencies:

bottle, hotqueue

## Getting Started

### Importing and using the plugin in Bottle

```python
import bottle
from bottlehotqueue import Plugin


app = bottle.Bottle()
hotqueue = Plugin(keyword="myhotqueue")
app.install(hotqueue)


@app.post('/add/:value', myhotqueue={'queue': 'myqueue'})
def send_message(value, myqueue):
""" This will put an item in the queue hotqueue:myqueue.
"""
return myqueue.put(value)


@app.get('/', myhotqueue={'queue': 'myqueue'})
def get_message(myqueue):
""" We will now try to get a item from hotqueue:myqueue.
if the queue is empty, we instead raise a 404.
"""
result = myqueue.get()
if not result:
raise bottle.HTTPError(404, "Queue is Empty")
return result

bottle.run(app, host='', port=8080)
```

The plugin will use json (or simplejson if available) as the standard serializer. This behaviour can be reverted to match the default implementation by passing asjson=False when instantiating the plugin. It will then conform to the standard HotQueue way of serializing objects by using pickle (or cpickle if available).

```python
hotqueue = Plugin(keyword="myhotqueue", asjson=False)
```

### Writing a simple consumer

```python
import json
from hotqueue import HotQueue


queue = HotQueue("myqueue", host="localhost", serializer=json)

for item in queue.consume():
print item

```
