Lightbulb is designed to be an easy to use command handler library that integrates with the Discord API wrapper library for Python, Hikari.

This library aims to make it simple for you to make your own Discord bots and provide all the utilities and functions you need to help make this job easier.

Use the package manager pip to install Lightbulb.

pip install hikari-lightbulb

# Import the command handler
import lightbulb
from lightbulb import commands

# Instantiate a Bot instance
bot = lightbulb.BotApp(token="your_token_here", prefix="your_prefix_here")

# Register the command to the bot
@bot.command
# Use the command decorator to convert the function into a command
@lightbulb.command("ping", "checks the bot is alive")
# Define the command type(s) that this command implements
@lightbulb.implements(commands.PrefixCommand)
# Define the command's callback. The callback should take a single argument which will be
# an instance of a subclass of lightbulb.Context when passed in
async def ping(ctx: lightbulb.context.Context) -> None:
    # Send a message to the channel the command was used in
    await ctx.respond("Pong!")

# Run the bot
# Note that this is blocking meaning no code after this line will run
# until the bot is shut off
bot.run()

If you find any bugs, issues, or unexpected behaviour while using the library, you should open an issue with details of the problem and how to reproduce if possible. Please also open an issue for any new features you would like to see added.
