See `defsetf' for a simpler way to define most setf-methods. This macro is an easy-to-use substitute for `define-setf-method' that works well for simple place forms. In the simple `defsetf' form, `setf's of the form (setf (NAME ARGS...) VAL) are transformed to function or macro -calls of the form (FUNC ARGS... VAL). Example: (defsetf aref aset). +calls of the form (FUNC ARGS... VAL). Example: + + (defsetf aref aset) + Alternate form: (defsetf NAME ARGLIST (STORE) BODY...). Here, the above `setf' call is expanded by binding the argument forms ARGS according to ARGLIST, binding the value form VAL to STORE, then executing BODY, which must return a Lisp form that does the necessary `setf' operation. Actually, ARGLIST and STORE may be bound to temporary variables which are introduced automatically to preserve proper execution order of the arguments. -Example: (defsetf nth (n x) (v) (list 'setcar (list 'nthcdr n x) v))." +Example: + + (defsetf nth (n x) (v) (list 'setcar (list 'nthcdr n x) v)) + +\(fn NAME [FUNC | ARGLIST (STORE) BODY...])" (if (listp arg1) (let* ((largs nil) (largsr nil) (temps nil) (tempsr nil) -- cgit v1.2.3
