primitives. Codepoint is an effort to extend LambdaMOO to support Unicode characters. Originally the project was started by H. Peter Anvin using libucd, a small library that implements features of the Unicode Character Database without being unwieldy. The project is now being developed by James C. Deikun, Robert Leslie, and Kenny Root with the goal of eventually integrating it into the main LambdaMOO distribution. ToastStunt is a fork of the Stunt server intended primarily to add new features. These include 64-bit integers, SQLite support, Perl-compatible regular expressions, background threaded functions, Argon2id hashing, telnet IAC capturing, profiling support, performance improvements, and dozens of additional built-in functions and improvements. Non-descendant MOOs Some servers use "MOO" style object-oriented characteristics without being descended from the original MOO server, in the sense that they use little or none of that server's source code and use internal languages that are more or less incompatible with the MOO programming language. None of them have attained the popularity of LambdaMOO or its relatives. Stephen White went on to write a new and similar system called CoolMUD, although it never obtained the same wide userbase as MOO. Another, later, attempt at a programmable object-oriented MUD server was ColdMUD, written by Greg Hudson and later maintained by Brandon Gillespie under the name "Genesis". One unusual MOO with no real relationship to the original MOO is called mooix. mooix is unique among MUDs in that it uses the underlying UNIX operating system to handle all of the multitasking and networking issues. Several unique side effects result from this, one of which is that the MOO can be programmed in any language. mooix was written after a failed attempt by Joey Hess to write a MOO entirely in Perl, called perlmoo. Access Participants (usually referred to as users) connect to a MOO using telnet or some other, more specialized, client program. Upon connection, they are usually presented with a welcome message explaining how to either create a new character or connect to an existing one. Almost every command is parsed by the server into a call on a MOO procedure, or verb, which actually does the work. Thus, programming in the MOO programming language is a central part of making non-trivial extensions to the database and hence the virtual reality. Administration All MOOs provide a flag called Wizard; when set on a player, the player gains the ability to view and modify
