## Features

* TODO

## Quickstart

### Subscriber

To create handler for particular subscription topic decorate your function using `subscribe` decorator:

```python
import pyhermes

@pyhermes.subscriber(topic='pl.allegro.pyhermes.sample-topic')
def handler(data):
# process data
```

This function will be called every time there is new message published to the selected topic.

### Publisher
Use `publish` function to publish data to some topic in hermes:

```python
import pyhermes

@pyhermes.publisher(topic='pl.allegro.pyhermes.sample-topic')
def my_complex_function(a, b, c):
result = a + b + c
publish(my_complex_function._topic, {'complex_result': result})
```

You could publish directly result of the function as well:

```python
import pyhermes

@pyhermes.publisher(topic='pl.allegro.pyhermes.sample-topic', auto_publish_result=True)
def my_complex_function(a, b, c):
return {'complex_result': a + b + c}
```

Result of decorated function is automatically published to selected topic in hermes.

## Running Tests
