# Snekbot API
This is the Snekbot API. This document describes how to create a bot responding to "hello", "bye" and "@username-of-bot".
## 5 minute tutorial
Literally.
### Installation
#### Requirements:
Python:
- python3
- python3-venv
- python3-pip
Use apt or your package manager to install these packages. There is a big chance your system already has them.
For Debian (Ubuntu): `sudo apt install python3 python3-venv python3-pip -y`
#### Environment
- `python3 -m venv venv`
- `source venv/bin/activate`
- `pip install git+https://molodetz.nl/retoor/snekbot.git`
#### Create account
Create regular user account for your bot. You need this later in your script.
Make sure you have this information right now:
- bot username
- bot password
- bot url (wss://your-snek-instance.com/rpc.ws)
#### Create a file
Open a file ending with the `.py` extension and paste this content. Replace the authentication details on the bottom lines with the one of the account you just created.
```python
import asyncio
from snekbot.bot import Bot
class ExampleBot(Bot):
async def on_join(self, channel_uid):
print(f"I joined!")
await self.send_message(
channel_uid,
f"Hello, i'm actively part of the conversation in channel {channel_uid} now, you don't have to mention me anymore. "
)
async def on_leave(self, channel_uid):
print(f"I left!!")
await self.send_message(
channel_uid,
"I stop actively being part of the conversation now. Bye!"
)
async def on_ping(self,username, user_nick, channel_uid, message):
print(f"Ping from {user_nick} in channel {channel_uid}: {message}")
await self.send_message(
channel_uid,
"pong " + message
)
async def on_own_message(self, data):
print(f"Received my own message: {data.message}")
async def on_mention(self, username, user_nick, channel_uid, message):
message = message[len(self.username) + 2 :]
print(f"Mention from {user_nick}: {message}")
if "source" in message:
with open(__file__) as f:
result = f.read()
result = result.replace(f'"{self.username}"', '"example username"')
result = result.replace(self.password, "example password")
result = (
"This is the actual source code running me now. Fresh from the bakery:\n\n```python\n"
+ result
+ "\n```"
)
await self.send_message(channel_uid, result)
else:
await self.send_message(channel_uid, f'Hey {user_nick}, Thanks for mentioning me "{message}".')
async def on_message(self, sender_username, sender_nick, channel_uid, message):
print(f"Message from {sender_nick}: {message}")
if not self.has_joined(channel_uid):
print(f"Probably not for me since i'm not mentioned and not joined yet")
return
message = message.lower()
result = None
if "hello" in message:
result = f"Hi @{sender_nick}"
elif "bye" in message:
result = f"Bye @{sender_nick}"
if result:
await self.send_message(channel_uid, result)
bot = ExampleBot(url="ws://snek.molodetz.nl/rpc.ws", username="example", password="example")
asyncio.run(bot.run())
```
#### Run the bot
Make sure you have (still) activated your virtual env.
```bash
python [your-script].py
```
If you get the error 'python not found' or 'aiohttp not found', run `source .venv/bin/activate` again and run `python [your script].py` again.
#### Debugging
Add `import logging` and `logging.BasicConfig(level=logging.DEBUG)`.
#### Summary
The `ExampleBot` class inherits from a base `Bot` class and implements several event handlers:
- `on_join`: Sends a welcome message when the bot joins a channel.
- `on_leave`: Sends a goodbye message when the bot leaves.
- `on_ping`: Responds with "pong" when it receives a ping message.
- `on_own_message`: Logs messages sent by the bot itself.
- `on_mention`: Handles mentions; if "source" is in the message, it replies with its own source code, with sensitive data disguised.
- `on_message`: Responds to "hello" and "bye" messages if the bot has joined the channel.
The bot will be instantiated and runs asynchronously. It will survive server deploys and network outages. If such issue occurs, it will try to reconnect within a second like nothing happened. It's production ready.
