## Codebases and drivers

- [Full chronology](https://en.wikipedia.org/wiki/Chronology_of_MUDs) of the most important MUDs and codebases in the Wikipedia.

- [Online World Timeline](https://www.raphkoster.com/gaming/mudtimeline.shtml) on Raph Koster's web page, shows a chronology of everything related to online worlds, including MUDs.

### MUD1

[MUDs](https://en.wikipedia.org/wiki/MUD) evolved from the [original game](https://en.wikipedia.org/wiki/MUD1) (created in 1978 in the University of Essex by Roy Trubshaw and Richard Bartle), in _families_ of related games, mainly based in the technologies used to implement them.

- Original [MUD1 source code](https://github.com/PDP-10/MUD1) for the DEC PDP-10 mainframe.

- Chronology of the [original MUD variants](https://mud.co.uk/richard/incarns.htm), by Richard Bartle.

- [British Legends](http://www.british-legends.com), home of the MUD1 game.

### AberMUD

Created in 1987 at the Aberystwyth University, was the first popular open source MUD. Ported to C in 1988 in AberMUD2, and published as GPL in AberMUD V. It inspired the next three major codebases: [TinyMUD](#TinyMUD), [LPMud](#LPMud) and [DikuMUD](#DikuMUD).

- [Family tree](https://en.wikipedia.org/wiki/MUD_trees#AberMUD_family_tree).

- [Some documentation and source code](http://ftp.linux.org.uk/pub/linux/alan/Software/Games/AberMUD5/) for AberMUD5 in http://ftp.linux.org.uk.

### TinyMUD

Released by Jim Aspnes in 1989, running on Unix and written in C.

- [Family tree](https://en.wikipedia.org/wiki/MUD_trees#TinyMUD_family_tree).

- [Source code](https://archive.org/details/tinymud-1.5.5) of v1.5.5 on the Internet Archive.

_MU*_, sometimes called *Tiny family*, is an abbreviation which refers collectively to a family comprising: TinyMUD, MUSH, MOO, TinyMUCK. It has [its own wiki](https://mu.fandom.com).

#### [MUSH](https://en.wikipedia.org/wiki/MUSH)

Main variations: PennMUSH, TinyMUSH, [TinyMUX](http://www.tinymux.org/) and [RhostMUSH](https://code.google.com/p/rhostmush/).

- Lots of code and documentation on [MUSHCode](http://www.mushcode.com/).

#### [TinyMUCK](https://en.wikipedia.org/wiki/TinyMUCK)

Written by Stephen White in 1990. Later that year, he released [MOO](#moo).

- [MUCK Manual](http://www.rdwarf.com/users/mink/muckman/) ([alt link](https://fuzzball-muck.github.io/muckman/)).

- [Fuzzball MUCK server](https://github.com/fuzzball-muck/fuzzball) source code.

#### [MOO](https://en.wikipedia.org/wiki/MOO)

Written by Stephen White in 1990, derived from TinyMUCK, with object oriented design. Pavel Curtis did substantial modifications to MOO code, creating LambdaMOO, which was hosted at Xerox PARC.

- Documentation in the [moo-cows](http://www.moo-cows.com/) web.

- List of MOO games in [moolist](http://www.moolist.com/).

- [LambdaMOO](https://en.wikipedia.org/wiki/LambdaMOO) was created in 1990 by Pavel Curtis ([source code in sourceforge](https://sourceforge.net/projects/lambdamoo/)).

- [Stunt](http://stunt.io/), a set of extensions to the LambdaMOO server.

- [ToastStunt](https://github.com/lisdude/toaststunt), forked from stunt and being worked on.

- [LambdaMOO Programming](https://github.com/sevenecks/lambda-moo-programming) repository, collects and updates numerous MOO guides in one place, from the original server to ToastStunt. 

### LPMud

Released by Lars Pensjö in 1989, trying to combine the extensibility of [TinyMUD](#TinyMUD) with the adventures of [AberMUD](#AberMUD). He designed the LPC language (from Lars Pensjö C) and the *driver/interpreter*, trying to make the process of extending the game easier, separating the Mud in two different parts: the **driver** which acts as a *virtual machine/interpreter/runtime* (programmed in C), and the **mudlib** which implements the game code (programmed in LPC and executed by the *driver*). Some old games still being played today started here: [Genesis](https://www.genesismud.org/), [BatMUD](https://www.bat.org/), [NannyMUD](https://www.lysator.liu.se/nanny/), [Discworld](http://discworld.starturtle.net), etc.

- [LPC Basics](https://www.lysator.liu.se/nanny/wiz/lpc/basic/Contents.html) and [Intermediate LPC](https://www.lysator.liu.se/nanny/wiz/lpc/intermediate/Contents.html), written for LPMud by George Reese (Descartes of Borg).

- [Self Conscious DGD](https://noahgibbs.github.io/self_conscious_dgd/), book about LPC for DGD written by [Noah Gibbs](https://codefol.io/).

#### Drivers

##### LPMud

After Lars Pensjö retired from LPMud development, Joern Rennecke (Amylaar) took over development of the LPMud driver and produced the 3.2 series of LPMud. This is sometimes known as the Amylaar driver.

- Source code not found in any repository, but the [MUDBytes files archives](http://mudbytes.net/files/tags/LPMud/) seems to have some versions uploaded.

##### MudOS

Another group of people started working from the LPMud v3.0 in 1992, and renamed it to MudOS, which will have several versions until 2003. (_mudos.org_, its original webpage is defunct, but you can find some of the last versions in the [maldorne repository](https://github.com/maldorne/mudos), and use them with Docker). It could use sockets at mudlib level (with LPC code), which allowed to create a TCP intermud network. This protocol evolved until [Intermud 3](#Intermud).

- [Code repository](https://github.com/maldorne/mudos) (fork).

- [History of MudOS](./docs/lpmuds/mudos-history.md) (recovered file from some driver distributions).

##### FluffOS

In parallel to the last versions of Mudos (the last one was v22.2b14, 2003), the Discworld developers forked it and renamed it as [FluffOS](http://fluffos.info/). [Still maintained](https://github.com/fluffos/fluffos). It had versions 1.0 to 1.36, 2.0 to 2.27, and since 3.0 the maintainer is [Yucong Sun](https://github.com/thefallentree), and major versions has been released with the names FluffOS 2017 and 2019.

- [Official code repository](https://github.com/fluffos/fluffos).

##### LDMud

Lars Düning continued the development of the LPMud driver renaming it to [LDMud](http://www.ldmud.eu) (but keeping the Amylaar version numbers, so starting with 3.2.2). LDMud is still [being maintained](https://github.com/ldmud/ldmud).

- [Official code repository](https://github.com/ldmud/ldmud).

##### CD MUD

- [Code repository](https://github.com/cotillion/cd-gamedriver).

##### DGD

Felix 'Dworkin' Croes developed in 1993 [DGD](http://www.dworkin.nl/dgd/) (Dworkin Game/Generic Driver), not derived from LPMud (so not using the same license) but compatible with LPC language. [Still maintained](https://github.com/dworkin/dgd), and open source since v1.4 (2010).

- [Official code repository](https://github.com/dworkin/dgd).

- [Self Conscious DGD](https://noahgibbs.github.io/self_conscious_dgd/), book about LPC for DGD written by [Noah Gibbs](https://codefol.io/).

### DikuMUD

Inspired by [AberMUD](#AberMUD) and [LPMud](#LPMud), created in 1990/91 at DIKU (*Datalogisk Institut Københavns Universitet* —the department of computer science at the University of Copenhagen—) in Copenhagen, Denmark.

- [DikuMUD III source code](https://github.com/Seifert69/DikuMUD3), using HTML, websockets and Discord integration, being worked on, LGPL license.

- The [DikuMUD Omnibus Github repository](https://github.com/DikuMUDOmnibus) stores more than a hundred Diku-related software projects.

Some well-known derivatives of DikuMUD: [CircleMUD](https://muds.fandom.com/wiki/CircleMUD) ([web](https://www.circlemud.org/), [source](https://www.circlemud.org/pub/CircleMUD/)), [MERC](https://muds.fandom.com/wiki/Merc), [Envy](https://muds.fandom.com/wiki/Envy), [ROM](https://muds.fandom.com/wiki/ROM), [SMAUG](https://muds.fandom.com/wiki/SMAUG), [GodWars](https://muds.fandom.com/wiki/GodWars), [AwakeMUD](https://muds.fandom.com/wiki/AwakeMUD) ([web](https://www.awakemud.com/), [source](https://github.com/luciensadi/AwakeMUD)).

## Protocols 

- Some info taken from the [tintin/mudhalla protocols and standards documentation](https://tintin.mudhalla.net/protocols/). 

- The [Mudlet wiki](https://wiki.mudlet.org/w/Main_Page) has a main page about all the [supported protocols](https://wiki.mudlet.org/w/Manual:Supported_Protocols) that could be useful too.

- CryoSphere MUD has a [page about MUD client/server interaction](http://cryosphere.net/mud-protocol.html) with some more useful information.

### Generic protocols for remote connections

#### Character Mode

Directly transmit the mud client's input, required for BBSes, \*NIX servers, Roguelike MUDs, and interaction with other console software.

#### NAWS

*Negotiate About Window Size*. Sends the mud client's window size to the server. [RFC 1073](https://www.rfc-editor.org/rfc/rfc1073).

### Specific protocols for MUDs

There are two **RFCs** about telnet negotiation: [854](https://www.rfc-editor.org/rfc/rfc854.html) and [855](https://www.rfc-editor.org/rfc/rfc855.html). Some of the next protocols are implemented as telnet options, expanding on these two.

#### GMCP

*Generic Mud Communication Protocol*. GMCP is implemented as a Telnet option. Uses JSON syntax to define structured and typed data.
