**pyobservable** is a minimalist event system for python. It provides you an easy-to-use interface to trigger arbitrary functions when specific events occur.

```python
from observable import Observable

obs = Observable()

@obs.on("error")
def error_handler(message):
    # do some fancy error handling
    logging.error(f"An error occured: {message}")

...

def do_time_travel():
    # do some time traveling
    ...
    if year != 1291:
        obs.trigger("error", "Time travel to 1291 didn't work")
```

**Note:** We are Python 3 only! Only Python Versions >= 3.5 are supported. Use [v0.3.2](https://pypi.org/project/observable/0.3.2/) for older Python Versions.

## How to use

Use a `pip` to install it from PyPI:

    pip install observable

After completion you can start using `observable`:

```python
from observable import Observable

obs = Observable()
```

## Usage

### `on`: Register event handler with `on`
There are two ways to register a function to an event.<br />
The first way is to register the event with a decorator like this:

```python
@obs.on("error")
def error_func(message):
    print("Error: %s" % message)
```

The second way is to register it with a method call:

```python
def error_func(message):
    print("Error: %s" % message)
obs.on("error", error_func)
```

### `once`: Register event handler with `once`
`once` works like `on`, but once the event handler is triggered it will be removed and cannot be triggered again.

### `trigger`: trigger event
You can trigger a registered event with the `trigger` method:

```python
obs.trigger("error", "This is my error message")
```

If no handler for the event `error` could be found an `Observable.NoHandlerFound`-Exception will be raised.

### `off`: remove handler and events
Remove a handler from a specified event:

```python
obs.off("error", error_func)
```

```python
obs.off("error", [error_func, second_error_func])
```

Remove all handlers from a specified event:

```python
obs.off("error")
```

Clear all events:

```python
obs.off()
```

### `get_all_handlers`, `get_handlers` and `is_registered`: Check which handlers are registered
Imagine you registered the following handlers:

```python
@obs.on("success")
def success_func():
    print("Success!")

@obs.on("error")
def error_func(message):
    print("Error: %s" % message)
```

Then you can do the following to inspect the registered handlers:
```python
>>> obs.get_all_handlers()
{'success': [<function success_func at 0x7f7f32d0a1e0>], 'error': [<function error_func at 0x7f7f32d0a268>]}
>>> obs.get_handlers("success")
[<function success_func at 0x7f7f32d0a1e0>]
>>> obs.get_handlers("other_event")
[]
```
