你非常接近,小的编辑会给你一个有效的解决方案。问题是你在混合符号和字符串。这将起作用:
(defmacro ssm-list-prop-defun (field)
;; note that concat operates on strings
`(defun ,(intern (concat "ssm-list-" field))
(one-list)
;; note that you need a symbol here, so quote the
;; result of the call to intern
;; and, if you're always using symbols,
;; might as well use assq
(cdr (assq ',(intern field) (car (cdr one-list))))))
;; pass in a string
(ssm-list-prop-defun "name")
下面是使用符号的变体:
;; variant that works off a symbol
(defmacro ssm-list-prop-defun (field)
`(defun ,(intern (concat "ssm-list-" (symbol-name field)))
(one-list)
(cdr (assq ',field (car (cdr one-list))))))
(ssm-list-prop-defun name)
