Subject: reserved-keyword in macro
Date: Wed, 2 Feb 2022 11:13:53 +0100 [thread overview]
Message-ID: <CADEOadckTDT=fR4UaG+X8eBKc3Xn=pLi2U3w3dy2kd=-UKyOjw@mail.gmail.com> (raw)
hello,
what is the best way to use a reserved keyword in a macro (a keyword for me
not already used in scheme):
if i have multiple patterns in a macro,for example:
(define-syntax macro
(syntax-rules ()
((_ arg1 arg2) code1)
((_ reserved-keyword arg) code2)))
now if i call the macro with (macro reserved-keyword 777) code1 is expansed
but not code2
i can merge code1 and code2 and do some inner test to check
reserved-keyword like this:
(if (equal? (quote arg1) (quote reserved-keyword)) ;; test
which had worked in past but is there a better way like :
(define-syntax macro
(syntax-rules (reserved-keyword)
but i can not fix it to work.
regards,
damien
