common-lisp CLOS Meta-Object Protocol Obtain the slot names of a Class
Example
Lets say we have a class as
(defclass person ()
(name email age))
To obtain the names of the slots of the class we use the function class-slots. This can be found in the closer-mop package, provided by the closer-mop system. To load it the running lisp image we use (ql:quickload :closer-mop). We also have to make sure the class is finalized before calling class-slots.
(let ((class (find-class 'person)))
(c2mop:ensure-finalized class)
(c2mop:class-slots class))
which returns a list of effective slot definition objects:
(#<SB-MOP:STANDARD-EFFECTIVE-SLOT-DEFINITION S/TRANSFORMATIONS::NAME>
#<SB-MOP:STANDARD-EFFECTIVE-SLOT-DEFINITION S/TRANSFORMATIONS::EMAIL>
#<SB-MOP:STANDARD-EFFECTIVE-SLOT-DEFINITION S/TRANSFORMATIONS::AGE>)
