Mudlle

Mudlle (MUD Language for Little Extensions) is the online programming language designed especially for MUME.

It allows the creation of intelligent mobiles, rooms, and objects. One example of a mudlled object is the whetstone (if you are lucky enough to find one). Mudlle is quite similar to the programming language Scheme (a Lisp dialect).

Example code

This mudlle program on a mobile would cause it to repeat anything said by a player in the same room:

module
[
  | repeat | // Define repeat as a local variable 
 
  repeat = fn (me, who, verb, args) [
    if (verb == CMD_SAY && !is_mobile?(who))
      [ 
        // The one who said something not a mobile.
        actor = me;
        say (args)
      ];
  ];
 
  react_event (repeat, "Function that makes a mob repeat says",
               event_command);
]
