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
