Preferences

Preferences are per-character settings you manage with the set command. They control colour, paging, notifications, GMCP, and — for wizards — a handful of custom messages and debugging aids.

Setting a Preference

set <preference> <value>     set a preference
set <preference>             clear a preference
set                          list your current preferences

For any preference whose name ends in _colour, you can pick a colour interactively instead of typing a code:

set highlight_colour prompt

Player Preferences

These apply to every character.

Administrator Preferences

These additional preferences are available to wizards. The custom-message preferences substitute tokens into the text you provide; you may also write your name in literally if you prefer.

Preference	Description
`log_level`	Verbosity of body/user event logging to `debug.log`, `1` (least) to `4` (most). `0` or unset disables it. Generates a lot of output — remember to turn it off.
`look_filename`	Show source filenames on `look`. `on` shows for rooms only, `all` shows for rooms and objects, `off` shows neither.
`custom_clone`	Message printed when you clone an object. `$N` -> your name, `$O` -> the object’s name.
`custom_dest`	Message printed when you destruct an object. `$N` -> your name, `$O` -> the object’s name.
`move_in`	Message shown to the room you move into. `$N` -> your name, `$D` -> the exit used.
`move_out`	Message shown to the room you move out of. `$N` -> your name, `$D` -> the exit used.
`teleport_in`	Message shown to the room you teleport into. `$N` -> your name, `$D` -> the destination.
`teleport_out`	Message shown to the room you teleport from. `$N` -> your name, `$D` -> the origin.
`start_location`	Where you log in. Defaults to the workroom in your home directory if it exists, otherwise the standard player start.
