Commands that the client sends to the bridge.
Each client is expected to send discrete commands that will
be processed individually.
The command format is identical to the message format, and is meant
to be very easy for the client to generate. Clients should typically
flush the stream after printing their command to ensure that the server
gets the input.
The type of the command governs how the server should send the result
back to the client. The currently supported command types are:
- LISP -- send only the first return value, and just use prin1 to
- LISP_MV -- send all of the return values, essentially by doing
prin1 on the multiple-value-list of the result.
- JSON -- send the json-encoding of the first return value. Note
that this encoder only handles good ACL2 objects.
- JSON_MV -- send the json-encoding of the
multiple-value-list of the result. Note that this encoder only handles
good ACL2 objects.
Adding other types would be trivial. For instance, it might be useful to
