cbot status

CBot is a chatbot written entirely in C!

Why would you do that? Because I can.


CBot can be used with the following chat systems:

  1. IRC
  2. Signal (thanks to the Signald API bridge)
  3. Your terminal (this one is pretty lonely)


These are some more interesting ones.

  • karma: Tracks the karma of various words. Uses persistent storage so you'll never forget all those times you said "cbot--"
  • know: You can tell cbot to "know" what things are and ask it later. EG "cbot know that Taylor Swift is awesome", and then "cbot what is Taylor Swift?"
  • weather: Request weather at any zip code
  • reply: a configurable plugin for triggering responses to messages matching regex. Think of this as Slackbot responses but much better.
  • name: Responds to questions about CBot with a link to the github.
  • greet: Say hi back to people, as well as greet when they enter a channel, and say bad things when they leave. (IRC only)
  • sadness: Responds to some forms of insult with odd comebacks.


  • Both the chat backend (e.g. IRC or Signal) and the bot abilities (i.e. plugins) are modular. So it's easy (ish) to port CBot to Slack (pull requests welcome) or add a plugin that works on all of the above.
  • The bot and plugins can be configured via a libconfig file, allowing for lots of flexibility.
  • Plugins can store data in a persistent sqlite database. CBot comes with a straightforward schema migration system, and a set of macros which can help write query functions.
  • The entire bot framework is based on a lightweight threading system and event loop. This allows asynchronous I/O code, such as HTTP requests, to cooperatively multitask with the IRC loop without launching true OS threads and dealing with concurrency.
  • Several small utility APIs exist to assist in writing plugins:
    • Dynamic arrays, hash table, linked list, string builder via sc-collections
    • Tokenizing API for turning messages into command arguments via a simple quoting system
    • Argument parsing API via sc-argparse, in case you want to go full UNIX
    • String templating/formatting API based on callbacks
