LDMud is a game engine for text based multi-user dungeon games (MUDs),
in the "LP" heritage. In essence it is a virtual machine that allows
developers to implement MUD games ("mudlibs" in LD parlance) using the
LPC programming language.
In the project's own words:
> This is 'LDMud', a gamedriver for LPMuds. (LPC compiler, interpreter
> and runtime environment.)
>
> LDMud started as a project to clean up and modernize Amylaar's LPMud
> gamedriver. Primary goals are full documentation, a commented source
> body and out-of-the-box support for the major mudlibs, of which the

For nixpkgs the new LDMud addition is largely a standard derivation for
an autoreconf/automake based project. Some small tweaks are required to
get everything lined up between the Nix environment and the LDMud build
system.
The new LDMud derivation is placed in `pkgs/games/ldmud/` alongside
other MUD-related projects in the games category (e.g. `mudlet`,
`blightmud`).
LD offers a variety of optional features, some of which require heavier
dependencies (e.g. MySQL/Postgres client libraries). To support both
a minimal default build equal to what one gets using the upstream build
with no customization, and to also support a more useful fully featured
build, the LDMud derivation is added to `all-packages.nix` twice:
1. the `ldmud` attribute builds the minimal default configuration (just
the optional gcrypt and pcre options enabled, matching upstream).
2. the `ldmud-full` attribute builds LDMud with all of the optional
features enabled (database support, Python support, TLS support,
etc).

LDMud started as a project to clean up and modernize Amylaar's LPMud
|
|
gamedriver. Primary goals are full documentation, a commented source body
|
|
and out-of-the-box support for the major mudlibs, of which the commented
|
|
source body has been pretty much completed. During the course of work
|
|
a lot of bug fixes and improvements found their way into the driver - much
|
|
more than originally expected, and definitely enough to make LDMud
|
|
a driver in its own right.
