Please update defclass-std source #2454
Description
defclass-std provides a shorter defclass macro, and now a define-print-object/std macro.
- old source: https://github.com/EuAndreh/defclass-std but they archived the repository. So I didn't ping them.
- new source: https://github.com/lisp-maintainers/defclass-std where I added the short PRINT-OBJECT macro. The lisp-maintainers org isn't tied to one person.
(defclass/std example ()
((slot1 slot2 slot3)))
;; even shorter:
;; (class/std classname slot1 slot2 slot3)
(define-print-object/std example)expands to
(DEFCLASS EXAMPLE ()
((SLOT1 :ACCESSOR SLOT1 :INITARG :SLOT1 :INITFORM NIL)
(SLOT2 :ACCESSOR SLOT2 :INITARG :SLOT2 :INITFORM NIL)
(SLOT3 :ACCESSOR SLOT3 :INITARG :SLOT3 :INITFORM NIL)))
(defmethod print-object ((obj example) stream)
(print-unreadable-object (obj stream :type t :identity t)
(format stream \"~{~a~^ ~}\" (collect-object-slots obj))))
result:
(make-instance 'example)
;; #<EXAMPLE (SLOT1 NIL) (SLOT2 NIL) (SLOT3 NIL) {100ADFFF73}>While certainly a rite of passage, having such a quick macro is nice for prototyping and the upcoming AOC :p
Comparison to other libraries: this one is very light on dependencies and doesn't go too far.
