ft_irc

A simple IRC-like server implemented in C++98 (42 School ft_irc project).

Overview

This repository contains an implementation of an IRC-style server written in C++98.

The typical goals of the 42 ft_irc project are to:

• implement a TCP server that accepts multiple clients
• parse IRC commands/messages
• manage clients and channels
• handle basic authentication (PASS/NICK/USER) and messaging

Repository: otelliq/irc
Main project directory: ft_irc/ft_irc/
Default branch: main

Build

A Makefile is provided in ft_irc/ft_irc/.

make -C ft_irc/ft_irc

Note: the current Makefile uses AddressSanitizer (-fsanitize=address) and -g, which is great for debugging.

Run

After building:

./ft_irc/ft_irc/ft_irc <port> <password>

(Exact arguments may vary depending on your implementation—see main.cpp for the definitive usage.)

Connect with an IRC client

You can connect using an IRC client like HexChat or irssi (examples):

# Example (replace PORT and PASSWORD)
/nick mynick
/user myuser 0 * :Real Name

Or via netcat for basic testing:

nc 127.0.0.1 <port>

Notes

• The repo has both lowercase and uppercase Channel/Client files in different directories—this is fine on Linux, but can be confusing on case-insensitive filesystems.
• Consider adding a top-level .gitignore if you don’t want to commit *.o or the built binary.
