c634e4b516 chore: replace print with logging and make robot conditional
All print statements in the main program, and components used by the main program, have been replaced with appropriate logging statements. The connection to the robot now only gets made when it's possible, otherwise only the microphone will be run.

2132a74321 fix: allow access to state's exit_event while exiting
When exiting, the state's `is_initialized` flag is unset. Noticeable on Windows, when a thread tried to access the state's `exit_event` property to check whether it had been set, it would complain that the state was no longer initialized. Now, even when no longer initialized, if the `exit_event` is set, it will not raise an error when accessing this attribute.

d21c7fa423 fix: always use 1 audio channel
Before, I chose the number of audio channels that the microphone supports. Should be 1.

Nothing fancy yet. When we receive a message through ZeroMQ's PUB/SUB
architecture, we tell the robot to say it out loud.

# PepperPlus-RI
The robot interface is a high-level API for controlling the robot. It implements the API as designed: https://utrechtuniversity.youtrack.cloud/articles/N25B-A-14/RI-CB-Communication.
This is an implementation for the Pepper robot, using the Pepper SDK and Python 2.7 as required by the SDK.
## Installation
## Development environment
### Linux (or WSL)
Start off by installing [Pyenv](https://github.com/pyenv/pyenv?tab=readme-ov-file#installation) and walk through the steps outlined there (be sure to also add it to PATH). Also install the [Python build requirements](https://github.com/pyenv/pyenv/wiki#suggested-build-environment). Afterwards, install Python 2.7 and activate it for your current shell:
```bash

We depend on PortAudio for the `pyaudio` package, so install it with:
To be able to install the PyAudio Python package, you'll need to have the `portaudio` system package installed. On Debian or Ubuntu:
```bash
sudo apt install -y portaudio19-dev
```shell
sudo apt install portaudio19-dev
```
On WSL, also install:
```bash
sudo apt install -y libasound2-plugins
```
Install the required packages with
Then you can install the required packages with

You should now be able to run this project.
### macOS
### MacOS
Similar to Linux, but don't bother installing `pyenv` as it won't be able to install Python 2 on Apple Silicon. Instead, install Python 2.7.18 from the [Python website](https://www.python.org/downloads/release/python-2718/).
On ARM CPU's, pyenv doesn't want to install Python 2. You can download and install it from [the Python website](https://www.python.org/downloads/release/python-2718/).
Create the virtual environment as described above in the Linux section. Stop at the point where it shows you how to download the NaoQi SDK. Instead, use:
Create a virtual environment as described in the Linux section.
```shell
curl -OL https://community-static.aldebaran.com/resources/2.5.10/Python%20SDK/pynaoqi-python2.7-2.5.7.1-mac64.tar.gz
Then build `portaudio` for x86_64 CPU's.
Then follow the remaining installation instructions in the Linux section.
## Running
Assuming you have the virtual environment activated (`source .venv/bin/activate` on Linux) and that you have a virtual robot running on localhost you should be able to run this project by typing
```bash
python main.py --qi-url tcp://localhost:<port>
```
Then resume the steps from above.
## Usage
On Linux and macOS:
```shell
PYTHONPATH=src python -m robot_interface.main
```
On Windows:
```shell
$env:PYTHONPATH="src"; python -m robot_interface.main
```
With both, if you want to connect to the actual robot (or simulator), pass the `--qi-url` argument.
There's also a `--microphone` argument that can be used to choose a microphone to use. If not given, the program will try the default microphone. If you don't know the name of the microphone, pass the argument with any value, and it will list the names of available microphones.
## Testing
To run the unit tests, on Linux and macOS:
```shell
PYTHONPATH=src pytest test/
```
On Windows:
```shell
$env:PYTHONPATH="src"; pytest test/
```
### Coverage
For coverage, add `--cov=robot_interface` as an argument to `pytest`.
## GitHooks
To activate automatic commits/branch name checks run:
```shell
git config --local core.hooksPath .githooks
```
If your commit fails its either:
branch name != <type>/description-of-branch ,
commit name != <type>: description of the commit.
<ref>: N25B-Num's
where `<port>` is the port on which your robot is running.
