Runbullet

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

Installation

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);
• The name of the (virtual) PushBullet device used to listen for events (create one here).

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:

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:

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:

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