在sbcl中,我知道在defun中同時使用&可選鍵和&鍵時,我可以消除預期的消息,但這似乎在defmacro中不起作用。 (我應該重新設計/重寫,我知道,但是這是遺留代碼)sbcl:defmacro中的馬弗風格警告

當我編譯這個文件......

(declaim (sb-ext:muffle-conditions style-warning)) 

(defun wilma (&optional wilma1 &key wilma2 wilma3) 
    (declare (ignore wilma1 wilma2 wilma3))) 

(defmacro betty (&optional betty1 &key betty2 betty3) 
    (declare (ignore betty1 betty2 betty3))) 

......發生這種情況:

home:~/sbcl/experiments/style-warning.d$ sbcl --noinform 
* (compile-file "5.lisp") 

; compiling file "/u/home/sbcl/experiments/style-warning.d/5.lisp" (written 09 OCT 2017 03:31:44 PM): 
; compiling (DECLAIM (MUFFLE-CONDITIONS STYLE-WARNING)) 
; compiling (DEFUN WILMA ...) 
; compiling (DEFMACRO BETTY ...) 
; file: /u/home/sbcl/experiments/style-warning.d/5.lisp 
; in: DEFMACRO BETTY 
;  (DEFMACRO BETTY (&OPTIONAL BETTY1 &KEY BETTY2 BETTY3) 
;  (DECLARE (IGNORE BETTY1 BETTY2 BETTY3))) 
; 
; caught STYLE-WARNING: 
; &OPTIONAL and &KEY found in the same lambda list: (&OPTIONAL BETTY1 &KEY BETTY2 
;              BETTY3) 
; 
; compilation unit finished 
; caught 1 STYLE-WARNING condition 


; /u/home/sbcl/experiments/style-warning.d/5.fasl written 
; compilation finished in 0:00:00.018 
#P"/u/home/sbcl/experiments/style-warning.d/5.fasl" 
T 
NIL 
* (exit) 
home:~/sbcl/experiments/style-warning.d$ 

我如何抑制這些診斷?

編輯1:

由於這是遺留代碼,我會只是按摩它SBCL就緒,然後息事寧人,沒有理由我不能做這樣的事情的任何代碼使用它:

home:~/sbcl/experiments/style-warning.d$ sbcl --noinform 
* (with-open-file (*error-output* "/dev/null" :direction :output :if-exists :append) 
(compile-file "5.lisp")) 

; compiling file "/u/home/sbcl/experiments/style-warning.d/5.lisp" (written 09 OCT 2017 03:31:44 PM): 
; compiling (DECLAIM (MUFFLE-CONDITIONS STYLE-WARNING)) 
; compiling (DEFUN WILMA ...) 
; compiling (DEFMACRO BETTY ...) 

; /u/home/sbcl/experiments/style-warning.d/5.fasl written 
; compilation finished in 0:00:00.017 
#P"/u/home/sbcl/experiments/style-warning.d/5.fasl" 
T 
NIL 
* (exit) 
home:~/sbcl/experiments/style-warning.d$ 

但是有什麼可以抑制宏定義中的樣式警告嗎?

您需要之前運行

(declaim (sb-ext:muffle-conditions style-warning)) 

形式(defmacro betty ...)編譯。要做到這一點

一種方法是

$ sbcl --non-interactive --eval '(declaim (sb-ext:muffle-conditions style-warning))' --eval '(compile-file "5")' 
This is SBCL 1.4.0, an implementation of ANSI Common Lisp.

; /Users/sds/lisp/5.fasl written

該文件5.lisp只包含wilmabetty

(defun wilma (&optional wilma1 &key wilma2 wilma3) 
    (declare (ignore wilma1 wilma2 wilma3))) 

(defmacro betty (&optional betty1 &key betty2 betty3) 
    (declare (ignore betty1 betty2 betty3)))
