Client Messages

These are "out of band" commands sent from the client up to the server. The line prefix "#$#" ensures that the server grants special handling to the incoming line. It will neither pass it on for parsing as a user command, nor allow it to be read into a buffer (a la /INFO). The number of commands is fairly few, largely because #$# options does a better job than this interface.

There are only two messages which can be safely sent prior to the completion of the login process: #$# ping and #$# options. The former because it depends in no way on the state or validity of the user attached to the connection. The latter because the information is specially preserved in a list attached to the connection. When the login completes the list of options is then processed by the user object.

#$# client clientname version

Provides information about the connecting client and its revision number. This information is useful for temporary patches to the server when output is changed, and is provides statistical information for client developers themselves (see /DISPLAY CLIENTS). Older clients used this command to register with the server. The server would then assign options based on the client name and version. Newer clients use the #$# options command. It is still strongly advised you use this command so the server administrators can record client use for statistical reasons, and so older servers will properly assign at least default options.
 

#$# client_name clientname

Deprecated, please use #$# client instead.
 

#$# client_version version

Deprecated, please use #$# client instead.
 

#$# delimiters predelimiter postdelimiter

Deprecated, please use #$# options +leaf-cmd instead.
 

#$# export_file filetype lines [object]

Used to send files from the client into the lilyCore server. Please see FileManagement for more information on this command.
 

#$# help_indicies

Would the author of this message please document it?
 

#$# import_file

Used to fetch files to the client from the lilyCore server. Please see FileManagement for more information on this command.
 

#$# master_objects

This lists all of the properties, one per line, in root (#0) which are defined as an object number, and which contain property or verb definitions. This message is only for use by lilyPAD, and was built to help populate the 'Objects' dialog.
 

#$# options ...

Toggles support for a variety of client options. Some of these will change the nature of the connection between the client and the server, while others simply generate a message. See ClientOptions.
 

#$# ping

Enables an out-of-band mechanism for connection keepalives at the server-level. Previously clients used NOP statements like /WHY to manage a keep-alive, but this often resulted in such commands being made part of info and memo buffers. The reply to a #$# ping client message is the server message %PONG.
 

#$# props object

This lists all of the properties, one per line, on the object listed. The object can either be in standard MOO format, #number, or in root (#0) property name format, $foo.
 

#$# screen_width size

This sets the screen width used by the Core to format a wide variety of events, including CONNECT messages and emotes, for non-SLCP clients. The value must be between 40 and 300, inclusive. The user may check the current value with the /SET command. This value is nearly useless for SLCP clients since they have access to native screen size information.
 

#$# slcp-sync

Retransmits the entire SLCP database of %USER, %DISC, and %DATA messages. This command can be used to reload an SLCP database in the client if an object is missing.
 

#$# verbs object

This lists all of the verbs, one per line, on the object listed. The object can either be in standard MOO format, #number, or in root (#0) property name format, $foo.
 

#$# what object

This command is currently unimplemented.
 

#$# who object

This command is currently unimplemented.
 

#$# whoami

Immediately sends the %whoami server message.
