Cog Watch

Automatic hot-reloading for your discord.py command files.

cogwatch is a utility that you can plug into your discord.py bot (or various supported bot libraries) that will watch your command files directory (cogs) and automatically reload them as you modify or move them around in real-time.

No more reloading your commands manually every time you edit an embed just to make sure it looks perfect!

Features

• Automatically reloads commands in real-time as you edit them (no !reload <command_name> needed).
• Optionally handles the loading of all your commands on start-up (removes boilerplate).

Supported Libraries

cogwatch should work with any library that forked from discord.py. However, these libraries have been explicitly tested to work:

• discord.py
• nextcord
• discord4py
• disnake
• pycord

Getting Started

You can install the library with pip install cogwatch.

Import the watch decorator and apply it to your on_ready method and let the magic take effect.

See the examples directory for more details.

import asyncio
from discord.ext import commands
from cogwatch import watch


class ExampleBot(commands.Bot):
    def __init__(self):
        super().__init__(command_prefix='!')

    @watch(path='commands', preload=True) # This is all you need to add.
    async def on_ready(self):
        print('Bot ready.')

    async def on_message(self, message):
        if message.author.bot:
            return

        await self.process_commands(message)


async def main():
    client = ExampleBot()
    await client.start('YOUR_TOKEN_GOES_HERE')

if __name__ == '__main__':
    asyncio.run(main())

Configuration

These options can be passed to the decorator (or the class if manually initializing):

path: Path of the directory where your command files exist; cogwatch will watch recursively within this directory. Defaults to 'commands'.

preload: Whether to detect and load all cogs on start. Defaults to False.

colors: Whether to use colorized terminal outputs or not. Defaults to True.

default_logger: Whether to use the default logger (to sys.stdout) or not. Defaults to True.

loop: Custom event loop. Defaults to the current running event loop.

debug: Whether to run the bot only when the Python __debug__ flag is True. Defaults to True.

NOTE: cogwatch will only run if the __debug__ flag is set on Python. You can read more about that here. In short, unless you run Python with the -O flag from your command line, __debug__ will be True. If you just want to bypass this feature, pass in debug=False and it won't matter if the flag is enabled or not.

Logging

By default, the utility has a logger configured so users can get output to the console. You can disable this by passing in default_logger=False. If you want to hook into the logger -- for example, to pipe your output to another terminal or tail a file -- you can set up a custom logger like so:

import logging
import sys

watch_log = logging.getLogger('cogwatch')
watch_log.setLevel(logging.INFO)
watch_handler = logging.StreamHandler(sys.stdout)
watch_handler.setFormatter(logging.Formatter('[%(name)s] %(message)s'))
watch_log.addHandler(watch_handler)
