irsc

This repository contains code that has not been properly tested yet, continue at the risk of doing stupid things while discovering parts of this library don't work.

Overview

Want to build an IRC bot with low resource consumption? You might want to have a look at this library (maybe later, though).

This library is supposed to be a thin layer over the IRC protocol, doing all the network IO and event parsing for you. Right now, it only works, nothing more.

Features

• Semi-complete implementation of RFC2812
• Some CTCP support

Planned

• Higher-level wrapper, directly aimed at writing bots
• Lots of tests
• Some documentation (yeah, sure)

Example

Compiles and works with rustc 1.1.0-nightly (c4b23aec4 2015-04-29) and 3e898f8451229bcc4988b40e2edcaec348bf7f79 of this library.
