# Python DBUS examples
> A collection of python DBUS examples.
## Abstract
The first time I had to deal with python and DBUS I was overwhelmed by the lack
of concrete examples, so this repository was born. More documentation may be found in the comments.
## Dependencies
The following are python dependencies:
* dbus-python
* relies on libdbus-1-dev
* PyGObject
* relies on libgirepository1.0-dev
On a debian based system the os dependencies can be installed like this:
```
sudo apt install libdbus-1-dev libcairo2-dev libgirepository1.0-dev cmake
```
Easiest way of installing the python dependencies is using [virtualenv](https://virtualenv.pypa.io/) and installing dependencies via pip:
```
virtualenv venv
source venv/bin/activate
pip install -r requirements.txt
```
## Usage
In your first terminal run the **dbus monitor** and grep for the examples methods:
dbus-monitor | grep /tld/domain/sub
In a second terminal run the **reciever**:
./receiver.py
The receiver has a *catch all* handler, so a lot of output is expected there.
in a third terminal you can now either:
* Run the **invoker**, which will call the proxxied receivers Test object methods:
./invoker.py
The invoker will invoke 3 Methodes on the receiver:
* foo: This will simply return *Foo* as a string
* fail: Will trigger an exception in the receiver which the invoker can handle
* quit: Will stop the receiver
* run the **emitter**, which will emit a test signal and a quit signal:
./emitter.py
After running either of them, the *receiver will be stopped*.
