# nmdc-ircfrontend
An IRC protocol frontend for an NMDC server.
This program 'wraps' an NMDC server to make it available to IRC clients. It implements the IRC server protocol, but is not itself an IRC server, deferring to the upstream NMDC server in all salient cases. From a layering perspective it occupies the same position as the web interface.
The intent of this project is to expand client library and application support on platforms where the NMDC community has not been able to spend effort (e.g. Apple iOS client, ruby/rust/erlang libraries, greater choice in web interfaces).
TLS (SSL) support is not integrated. To host the IRC frontend over TLS, please use a reverse proxy in much the same manner as for NMDCS.
## License
This program uses some code from the AGPLv3 project https://github.com/eXeC64/Rosella , from which it inherits the Affero GPLv3 license. Anyone hosting a modified version of this software is required to release their changes under the terms of the AGPLv3.
## Features
- Seamless roundtrip transition between NMDC `/me` and IRC `CTCP ACTION`
- IRC client's "Real Name" exposed as NMDC Description
- IRC client's `CTCP VERSION` exposed as NMDC client tag, with heuristic truncation
- NMDC server's title exposed as IRC channel topic
- Login with passworded nick (classic `PASS`, not `SASL`)
- Full nick list integration including op status
- Support IRC client changing nick via NMDC upstream reconnection
- Automatic join to single-enforced chatroom
- Multithreaded
- Single binary deployment
## Usage
```
Usage of nmdc-ircfrontend:
-autojoin
Automatically join clients to the channel (default true)
-bind string
The address:port to bind to and listen for clients on (default ":6667")
-hubsecurity string
Nick used for administrative events (default "Hub-Security")
-servername string
Server name displayed to clients (default "nmdc-ircfrontend")
-upstream string
Upstream NMDC/ADC server (default "127.0.0.1:411")
-verbose
Display debugging information
```
## Compatibility
*This section was last updated on or around the release of 1.3.0. Current compatibility may differ.*
NMDC's smaller community has standardised around comparatively few protocol implementations by means of necessity. In comparison, there are a lot of IRC client implementations with slightly differing interpretations of the protocol.
For passworded DC usernames, your IRC PASS username must be the same as your IRC nickname.
Tested working:
- AndChat
- AndroIRC
- Atomic
- Hexchat
- HoloIRC
- Irssi
- LiteIRC
- Mango IRC
- mIRC 7
- Mutter
- Revolution IRC
- Weechat
- Yaaic
Unusable:
- Rocket.chat 0.6x IRC plugin (can join room and recieve PMs after some regex tweaking)
## Changelog
2018-03-24 1.3.0
- Feature: Support ADC hubs
- Compatibility: Fix missing userlist in LiteIRC (since 1.2.2)
- Compatibility: Avoid sending empty room list (fixes Yaaic, atomic, Revolution IRC)

BUGS
====
- /wrong/ password message shows up, but not if no password was given for a passworded nick
- tags not showing up in ncdc
WISHLIST
========
- verify PING responses (application-layer timeout protocol)
- automatic markdown bold/italic formatting
- support USERIP/KILL/KICK for ops
- use CTCP chat to support irc-special characters in chat messages (colon, newline)
WONTFIX
=======
There's no additional client compatibility gained by implementing the following
- support USERHOST (used by androirc)
2016/05/08 13:43:55 >>> 'USERHOST' [squirtle90]
2016/05/08 13:43:55 <<< :pokehub.info 421 squirtle90 USERHOST :Unknown command
- support WHOX
- support SASL PLAIN authentication as well as just classic PASS

=COMPATIBILITY=
*This section was last updated on or around the release of 1.2.0. Current compatibility may differ.*
NMDC's smaller community has standardised around comparatively few protocol implementations by means of necessity. In comparison, there are a lot of IRC client implementations with slightly differing interpretations of the protocol.
Everything works:
- Hexchat
- Mango IRC
- AndroIRC
- Mutter
- Weechat
- mIRC 7
- HoloIRC (after version 4.1.0)
Usable, with bugs:
- Lite IRC - The username and nickname fields must be identical
- HoloIRC (4.1.0 and earlier) - Can't parse client tag, upstream bug https://github.com/tilal6991/HoloIRC/issues/140
- AndChat - Duplicate usernames appear, upstream bug https://github.com/znc/znc/issues/424
- Irssi - Ignorable warning "critical nicklist_set_host: assertion 'host != NULL' failed"
Unusable:
- Yaaic and Atomic - doesn't properly understand/parse the room join
=CHANGELOG=
2017-05-28 1.2.3
- Fix a regression with userlist display on HexChat (other IRC client compatibility unknown)
2017-05-27 1.2.2
- Update libnmdc to 0.14

- Feature: Support WHOIS (display NMDC user's description + client software)
- Feature: `-version` command-line option
- Compatibility: Demote 'Lite IRC' to 'Usable with bugs' section
- Update libnmdc to r9 (fix protocol issues)
- Update golang to 1.7 (smaller binary size)
2016-05-10 1.1.0

Tiger cryptographic hash function for Go
-----
[![Build Status](https://travis-ci.org/cxmcc/tiger.svg?branch=master)](https://travis-ci.org/cxmcc/tiger)
[![GoDoc](http://godoc.org/github.com/cxmcc/tiger?status.png)](http://godoc.org/github.com/cxmcc/tiger)
### About Tiger
* Tiger cryptographic hash function is designed by Ross Anderson and Eli Biham in 1995.
* The size of a Tiger hash value is 192 bits. Truncated versions (Tiger/128, Tiger/160) are simply prefixes of Tiger/192.
* Tiger2 is a variant where the message is padded by first appending a byte 0x80, rather than 0x01 as in the case of Tiger.
* Links: [paper](http://www.cs.technion.ac.il/~biham/Reports/Tiger/), [wikipedia](http://en.wikipedia.org/wiki/Tiger_\(cryptography\))
### API Documentation
Implementing [hash.Hash](http://golang.org/pkg/hash/#Hash). Usage is pretty much the same as other stanard hashing libraries.
Documentation currently available at Godoc: [http://godoc.org/github.com/cxmcc/tiger](http://godoc.org/github.com/cxmcc/tiger)
