Function Entry: CLAL-DEFINE-DEBUGGER-COMMAND

clal-define-debugger-command

clautolisp Extension Function

(clal-define-debugger-command names function [doc])

• names — a list (key word …) of strings; the key must be the word initials (debugger command reference §0).
• function — a function designator; the command body, applied to the command's parsed string arguments at dispatch.
• doc — optional help string.

Register an AutoLISP debugger command (command reference §8). It funcalls the runtime's define-command hook with the unwrapped name strings, the resolved function, and the doc string. A no-op (returns nil) unless the debugger UI is loaded.

DEPRECATED: the equivalent of (clal-define-command "ALDO" names function [doc]) — new code names the interactor with clal-define-command.

Always nil.

When the debugger UI is loaded, adds a command to the debugger's command table; otherwise none.

• Whether the aldo debugger UI is loaded.

Argument-type errors propagate from unwrapping names and resolving function; otherwise none.

  '("wa" "watch")
