# Ergonomadic

Ergonomadic is an IRC daemon written from scratch in Go. Pull requests and
issues are welcome. Discuss it here or on Freenode in [#ergonomadic][irc].

## Some Features

- follows the RFCs where possible
- UTF-8 nick and channel names
- [gcfg][gcfg] gitconfig-style configuration
- server password (PASS command)
- channels with most standard modes
- IRC operators (OPER command)
- haproxy [PROXY protocol][proxy-proto] header for hostname setting
- passwords stored in [bcrypt][go-crypto] format
- channels that [persist][go-sqlite] between restarts (+P)
- messages are queued in the same order to all connected clients

## Users

If anyone is running and using this software, I'd love to link to you here with
any details you deem appropriate.

## Why?

I wanted to learn Go.

## What's with the name?

"Ergonomadic" is an anagram of "Go IRC Daemon".

## What about SSL/TLS support?

Go has a not-yet-verified-as-safe TLS 1.2 implementation. Sadly, many popular
IRC clients will negotiate nothing newer than SSLv2. If you want to use SSL to
protect traffic, I recommend using [stunnel][stunnel] version 4.56 with
haproxy's [PROXY protocol][proxy-proto]. This will allow the server to get the
client's original addresses for hostname lookups.

## What about federation?

IRC federation solves a problem that was more likely to occur on the internet of
1991 than today. We are exploring alternatives to federation that avoid nickname
and channel sync issues created during netsplits.

## Installation

```sh
go get
go install
ergonomadic initdb -conf ergonomadic.conf
```

## Configuration

See the example [`ergonomadic.conf`](ergonomadic.conf). Passwords are base64-encoded bcrypted byte
strings. You can generate them with the `genpasswd` subcommand.

```sh
ergonomadic genpasswd 'hunter2!'
```

## Running the Server

```sh
ergonomadic run -conf ergonomadic.conf
```
