Runbullet
=========

Execute any command or custom complex logic on your devices, wherever they are, using your PushBullet account.

Installation
------------

```shell
pip install runbullet
```

Configuration
-------------

Copy /etc/runbullet/config.example.yaml to /etc/runbullet/config.yaml (system-wise settings) or ~/.config/runbullet/config.yaml (user-wise settings).

Edit the file to include:

* Your PushBullet access token (create one [here](https://www.pushbullet.com/#settings/account));
* The name of the (virtual) PushBullet device used to listen for events (create one [here](https://www.pushbullet.com/#devices)).

Each target device is identified by a unique device_id in the messages sent over your account. The device_id is the hostname by default, unless changed in config.yaml.

Testing
-------

`runbullet` installs `pusher`, a command-line tool to send PushBullet messages to the connected devices in the format used by runbullet.

Some examples:

```shell
echo '{"cmd":"scp /home/user/photos/*.jpg backup_host:/mnt/hd/photos"}' | pusher --target laptop --action shell.exec
echo '{}' | pusher --target raspberrypi --action music.mpd.play
```

The logic to execute is specified by the `--action` option, whose format is `package_name.method_name` (with method_name part of the package main class).

Writing your plugins
--------------------

Writing your own `runbullet` plugin, that would execute your own custom logic whenever a bullet with your plugin name is received, is a very simple task.

1. Create your plugin directory under `runbullet/plugins` (e.g. `light/batsignal`).

2. In the case above, `runbullet.plugins.light.batsignal` will be your package name.

3. Create an `__init__.py` under `runbullet/plugins/light/batsignal`.

4. If your module is `light/batsignal`, then its main class should be named `LightBatsignalPlugin`.

5. The configuration for your module will be read from a section named `light.batsignal` from your `config.yaml`, the attributes are accessible in your class in `self.config`.

The `__init__.py` will look like this:

```python
import batman

from .. import LightPlugin

class LightBatsignalPlugin(LightPlugin):
    def _init(self):
        self.batsignal = batman.Batsignal(self.config['intensity'])

    def on(self):
        self.batsignal.on()

    def off(self):
        self.batsignal.off()

    def toggle(self):
        self.batsignal.toggle()

    def status(self):
        return [self.batsignal.status().stdout, self.batsignal.status().stderr]
```

6. It's a good practice to define a `status` method in your plugin, which returns a 2-items list like `[output, error]`.

7. Rebuild and reinstall `runbullet` if required and relaunch it.

8. Test your new plugin by sending some bullets to it:

```shell
echo '{}' | pusher --target your_pc --action light.batsignal.on
```
