Client base class example:
from pincer.client import Bot
# Note that both `Bot` and `Client` are valid!
bot = Bot("YOUR_TOKEN_HERE")
bot.run()
An example on the on_ready event
Pincer bots are required to inherit from the Client.
from time import perf_counter
from pincer import Client
marker = perf_counter()
class Bot(Client):
@Client.event
async def on_ready():
print(f"Logged in as {client.bot} after {perf_counter() - marker} seconds")
client = Bot("YOUR_TOKEN_HERE")
client.run()
Interactions
Pincer makes developing application commands intuitive and fast.
from pincer import Client
from pincer.commands import command, CommandArg, Description
from pincer.objects import UserMessage, User
class Bot(Client):
@Client.event
async def on_ready(self) -> None:
...
@command(description="Say something as the bot!")
async def say(self, message: str):
return message
@user_command
async def user_command(self, user: User):
return f"The user is {user}"
@message_command(name="Message command")
async def message_command(self, message: UserMessage):
return f"The message read '{message.content}'"
@command(description="Add two numbers!")
async def add(
self,
first: CommandArg[int, Description["The first number"]],
second: CommandArg[int, Description["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)
Middleware
The middleware system was introduced in version 0.4.0-dev. This system gives you the
freedom to create custom events and remove the already existing middleware created by
the developers. Your custom middleware directly receives the payload from
Discord. You can't do anything wrong without accessing the override attribute, but if
you do access it, 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
the middleware system with a custom on_ready event can be found
in our docs.
