Here goes the fixed version:
(require 'cl)
(defmacro concatenate-def-types-for-regexp (&rest symbols)
(with-output-to-string
(princ "(?\\(")
(let (not-first)
(while symbols
(if not-first
(princ "\\|")
(setq not-first t))
(princ (pop symbols))))
(princ "\\)")))
(defcustom lisp-indent-def-function-regexp
(concatenate-def-types-for-regexp
function macro compiler-macro method generic type print-object
class
condition)
"Definer types will be indented like a function definition form."
:type 'string
:group 'lisp-indent)
(defcustom lisp-indent-def-variable-regexp
(concatenate-def-types-for-regexp
variable constant load-time-constant special-variable symbol-macro
struct)
"Definer types will be indented like a variable definition form."
:type 'string
:group 'lisp-indent)
(defcustom lisp-indent-def-setf-regexp
(concatenate-def-types-for-regexp setf)
"Definer types will be indented like a setf definition form."
:type 'string
:group 'lisp-indent)
(defmacro with-position-at-def-type (position &rest body)
`(save-excursion
(goto-char ,position)
(forward-char)
(forward-sexp 1)
(while (forward-comment 1))
,@body))
(defun lisp-indent-def (path state indent-point sexp-column normal-
indent)
(lisp-indent-259
(with-position-at-def-type (elt state 1)
(cond ((looking-at lisp-indent-def-function-regexp)
'(4 4 &lambda &body))
((looking-at lisp-indent-def-variable-regexp)
'(4 4 &body))
((looking-at lisp-indent-def-setf-regexp)
'(4 4 &lambda &body))
(t
'(&body))))
path state indent-point sexp-column normal-indent))
(put 'def 'common-lisp-indent-function 'lisp-indent-def)
Pay attention that, in LISP-INDENT-DEF, if we couldn't find an
appropriate known definer type, we pass '(&body) to LISP-INDENT-259.
(Also fixed indentation routines in demacs too.)
