hata 1.1.86

A powerful asynchronous library for creating Discord bots in Python.

Hata

Hata is an async Discord API wrapper written in Python named after Hata no Kokoro.

If naming a Discord API wrapper after a Touhou character is not enough to convince you to try it, it has got some real stuff:

• Fast and simple asynchronous framework to write concurrent code using async/await syntax, but also great for embedding into a threaded system.
• Running more clients from the same instance.
• Shared entity cache between shards and clients.
• Feature rich API for common use cases.
• Fast rate limit handling.
• No member objects associated with guilds. Hata uses guild -> user -> guild relation enabling implementing cross-guild features more easily.
• Optimized dispatch event parsers depending on intents, client count and on handled events as well.
• Option to disable user presences or even user caching, although disabling user cache is not recommended.
• Many builtin extension. Including a slash command one as well.
• Audio sending and receiving.
• Can interact with the Discord API without gateway connection.
• Switching between api version with environmental variable.

Usage

The following example answers on ping message.

from hata import Client

Nue = Client('TOKEN')

@Nue.events
async def ready(client):
    print(f'{client:f} logged in.')

@Nue.events
async def message_create(client, message):
    if message.author.is_bot:
        return

    if message.content == 'ping':
        await client.message_create(message.channel, 'pong')

Nue.start()

An improved example using the commands extension to handle common use cases.

from hata import Client

Saki = Client('TOKEN', extensions='commands', prefix='s!')

@Saki.events
async def ready(client):
    print(f'{client:f} logged in.')

@Saki.commands
async def ping(client, message):
    return 'pong'

Saki.start()

Or use slash commands!

from hata import Client, Guild

GUILD = Guild.precreate(guild_id)

Seija = Client('TOKEN', extensions='slash')

@Seija.events
async def ready(client):
    print(f'{client:f} logged in.')

@Seija.interactions(guild=GUILD)
async def ping():
    """ping-pong"""
    return 'pong'

Seija.start()

Note: You need to restart your client, or the slash command wont show up. If there are more than 50 integrations (bots) in a guild, some of the (integrations) bots wont be able to use slash commands. This is currently a Discord limitation.

If you wonder, how to run up more clients, just put the two code snippet into the same file.

Hata leaves the main thread free, client.start() blocks it only till the client logs in (or fails it), although you can still use the start_clients function, what as it says, starts up all the non-running clients parallelly, so go ahead and start python with -i option, then interact with the clients from your interactive console in runtime.
