Client base class example:

An example on the on_ready event

from time import perf_counter
from pincer.client import Client

client = Client("...")


@client.event
async def on_ready():
    print(f"Logged in as {client.bot} after {perf_counter()} seconds")


client.run()

Inherited client

You have the possibility to use your own class to inherit from the Pincer bot base.

from pincer import Client, command, Descripted


class Bot(Client):
    def __init__(self) -> None:
        super(Bot, self).__init__(token="...")

    @Client.event
    async def on_ready(self) -> None:
        ...

    @command(description="Say something as the bot!")
    async def say(self, message: str):
        return message

    @command(description="Add two numbers!")
    async def add(
            self, 
            first: Descripted[int, "The first number"],
            second: Descripted[int, "The second number"]
    ): 
        return f"The addition of `{first}` and `{second}` is `{first + second}`"

Advanced Usage

Enable the debug mode

If you want to see everything that is happening under the hood, either out of curiosity or to get a deeper insight into the implementation of some features, we provide debug logging!

import logging

logging.basicConfig(level=logging.DEBUG)

Note: A lot of printing can happen, including sensitive information, so make sure to be aware of what you're doing if you're enabling it!

Middleware

From version 0.4.0-dev, the middleware system has been introduced. This system gives you the full freedom to remove the already existing middleware which has been created by the developers and create custom events. Your custom middleware directly receives the payload from Discord. You can't really do anything wrong without accessing the override attribute, but if you access this attribute the Pincer team will not provide any support for weird behavior. So in short, only use this if you know what you're doing. An example of using this with a custom on_ready event can be found in our docs .
