busylib 0.0.2

Python library for Busy Bar API

busylib

A simple and intuitive Python client for interacting with the Busy Bar API. This library allows you to programmatically control the device's display, audio, and assets.

Features

• Easy-to-use API for all major device functions.
• Upload and manage assets for your applications.
• Control the display by drawing text and images.
• Play and stop audio files.
• Built-in validation for device IP addresses.

Installation

You can install busylib directly from PyPI:

pip install busylib

Usage

First, import and initialize the BusyBar client with the IP address of your device.

from busylib import BusyBar

try:
    # Default IP is 10.0.4.20, but you can specify your own
    bb = BusyBar("192.168.1.100")
except ValueError as e:
    print(f"Error: {e}")

# Now you can use the bb object to interact with your device.

API Examples

Here are some examples of how to use the library to control your Busy Bar device.

Uploading an Asset

You can upload files (like images or sounds) to be used by your application on the device.

# Upload a file from bytes
with open("path/to/your/image.png", "rb") as f:
    file_bytes = f.read()
    bb.upload_asset(
        app_id="my-app",
        file_name="logo.png",
        file=file_bytes
    )

# Or upload directly from a file-like object
with open("path/to/your/sound.mp3", "rb") as f:
    bb.upload_asset(
        app_id="my-app",
        file_name="notification.mp3",
        file=f
    )

Drawing on the Display

Draw text or images on the device's screen. The draw_display method accepts a list of elements to render.

elements = [
    {
        "type": "text",
        "value": "Hello, World!",
        "x": 10,
        "y": 20,
        "color": "#FFFFFF" # Optional
    },
    {
        "type": "image",
        "path": "logo.png", # Must be uploaded first
        "x": 50,
        "y": 40
    }
]

bb.draw_display(app_id="my-app", elements=elements)

Clearing the Display

To clear everything from the screen:

bb.clear_display()

Playing a Sound

Play an audio file that you have already uploaded.

bb.play_sound(app_id="my-app", path="notification.mp3")

Stopping a Sound

To stop any audio that is currently playing:

bb.stop_sound()

Deleting All Assets for an App

This will remove all files associated with a specific app_id.

bb.delete_assets(app_id="my-app")

Development

To set up a development environment, clone the repository and install the package in editable mode with test dependencies:

git clone https://github.com/busy-app/busylib
cd busylib
python3 -m venv .venv
source .venv/bin/activate
make install-dev

To run the tests:

make test
