CHAPTER 27. COMMAND PROCESSING

The present presentation method for the command type must call the command unparser stored
in *command-unparser*.

If a presentation history is maintained for the command presentation type, it should be maintained
separately for each instance of an application frame.

=> command-name &key command-table [Presentation Type]
The presentation type used to represent the name of a command that is both accessible in
the command table command-table and enabled in *application-frame*. command-table is a
command table designator. If command-table is not supplied, it defaults to the command table
for the current application frame, (frame-command-table *application-frame*).

The textual representation of a command-name object is the command-line name of the command,
while the internal representation is the command name.

=> command-or-form &key command-table [Presentation Type]
The presentation type used to represent an object that is either a Lisp form, or a command and its
arguments. The command must be accessible in command-table and enabled in *application-
frame*. command-table is a command table designator. If command-table is not supplied,
it defaults to the command table for the current application frame, (frame-command-table
*application-frame*).

The accept presentation method for this type reads a Lisp form, except that if the first character
in the user's input is one of the characters in *command-dispatchers* it will read a command.
The two returned values from the accept presentation method will be the command or form
object and a presentation type specifier that is either command or form.

If a presentation history is maintained for the command-or-form presentation type, it should be
maintained separately for each instance of an application frame.

=> *command-dispatchers* [Variable]
This is a list of the characters that indicates that CLIM reads a command when it is accepting
a command-or-form. The standard set of command argument delimiters must include the colon
character, #\:.
