CHAPTER 27. COMMAND PROCESSING

=> command-table-already-exists [Error Condition]
The error that is signalled when the programmer tries to create a command table that already
exists.

=> command-not-present [Error Condition]
The error that is signalled when a command is not present in a command table.

=> command-not-accessible [Error Condition]
The error that is signalled when a command is not accessible in a command table.

=> command-already-present [Error Condition]
The error that is signalled when a function tries to add a command to a command table when
it is already present in the command table.

=> add-command-to-command-table command-name command-table &key name menu keystroke
(errorp t) [Function]
Adds the command named by command-name to the command table specified by the command
table designator command-table.

name is the command-line name for the command, and can be nil, t, or a string. When it is
nil, the command will not be available via command-line interactions. When it is a string, that
string is the command-line name for the command. When it is t, the command-line name is
generated automatically. (The automatically generated name consists of the command's name
with the hyphens replaced by spaces, and the words capitalized; furthermore, if there is a prefix
of "COM-", the prefix is removed. For example, if the command name is com-show-file, the
command-line name will be "Show File".) For the purposes of command-line name lookup, the
character case of name is ignored.

menu is a menu item for the command, and can be nil, t, a string, or a cons. When it is nil,
the command will not be available via menus. When it is a string, the string will be used as
the menu name. When menu is t and name is a string, then name will be used as the menu
name. When menu is t and name is not a string, an automatically generated menu name will be
used. When menu is a cons of the form (string . menu-options), string is the menu name and
menu-options consists of keyword-value pairs. The valid keywords are :after, :documentation,
and :text-style, which are interpreted as for add-menu-item-to-command-table.

The value for keystroke is either keyboard gesture name or nil. When it is a gesture name, it
is the keystroke accelerator for the command; otherwise the command will not be available via
keystroke accelerators.

If the command is already present in the command table and errorp is true, the command- already-presenterror will be signalled. When the command is already present in the command
table and errorp is false, then the old command-line name, menu, and keystroke accelerator will
first be removed from the command table.
