The LambdaMOO Programmer's Manual is a complete reference for all database-independent aspects of the LambdaMOO system, including the programming language, built-in functions, and command parser.
The Programmer"s Manual is available at ftp://ftp.research.att.com/dist/eostrom/MOO The file name is `ProgrammersManual.*' where `*' is the format tag. It is available in DVI, PostScript, TeXInfo, and plain text formats.
There is no easy way to merge databases. The easiest thing to do is just snag the code from LambdaMOO or somewhere and build/rebuild the objects by hand. (For information on how to do so, see `help @dump' on LambdaMOO.)
As documented in the Programmer's Manual Getting and Setting the Values of Properties, $name refers to the property on the system object (#0) named "name".
Therefore, object references such as `$player' are created by adding a property of that name to the system object (#0) and storing the appropriate object's number in that property. For example, referencing $room is the same as referencing #0.room.
When the verb
@make-core-database is run, it searches the
system object for these links in order to determine which objects
belong in the core. Newer releases of the LambdaMOO core include
the wizard verb
@corify which will add the specified object to
the core in the manner illustrated as well as checking additional
features such as an `init_for_core' verb being programmed on the
Mr. Spell is so large that he can't be deleted in the conventional manner. What you need to do is this:
;recycle($spell) @rmprop #0.spell
This leaves a hole in the database however. You can easily live with it but if you find that you can't, just fill it by doing this:
Another option is to call $spell:clearall() and recycle the object as usual. This takes longer, but it does leave you the option of using $spell later, or with a smaller dictionary (by not recycling it). $spell without the dictionary is not very big.
When the server starts, it calls the verb #0:server_started. Create or alter that verb to have it call the verb you want to execute.
If a task has suspended or forked, and its execution is still pending when the server checkpoints or is shutdown, that task is saved along with the rest of the database. Thus, when the server is restarted, that task will be resumed.
When something is said in a room, each object in that room is sent
that text via the verb
tell. You can change this verb to do whatever
you want it to whenever anything is said or done in a room.
Change the value of the property
#0.dump_interval to the desired
number of seconds between dumps; the change will take effect after the
