PyYapper

An intuitive, async Python library for the Yapper bot API. Designed to feel familiar to discord.py users while staying small and dependency-light.

Install

pip install pyyapper

Requires Python 3.9+ and aiohttp.

Quick start

from pyyapper import Bot

bot = Bot("yb_...")  # your token from Settings -> Developer


@bot.command("ping", description="Is the bot alive?")
async def ping(ctx):
    await ctx.reply("pong")


@bot.event
async def on_ready(me):
    print("online as", me.username)


bot.run()

Features

• Async-first, with a synchronous bot.run() entry point.
• Decorator-based commands and events (@bot.command, @bot.event, @bot.button).
• Rich message context: ctx.reply, ctx.say, ctx.author_mention, ctx.argv.
• Button/interaction helpers: i.reply, i.ephemeral, i.update, i.ack.
• Embed, Button, Row builders with chaining.
• Typed data models (User, Message, Channel, ...) and a full exception hierarchy.
• Automatic retry on 429 with Retry-After, exponential backoff, timeouts.
• Long-polling event loop with cursor tracking (nothing lost on reconnect).

Error handling

from pyyapper import Bot, NotFound, Forbidden, RateLimited

bot = Bot("yb_...")

async def main():
    try:
        await bot.delete("some-channel", "some-message")
    except NotFound:
        print("message already gone")
    except Forbidden:
        print("missing Manage messages permission")
    except RateLimited as e:
        print("slow down, retry after", e.retry_after)

import asyncio
asyncio.run(main())
