I have a macro (let's called it X) that generates unique symbols at
all its uses. I need all its uses to be distinguishable from each
other.
(define-syntax X
(syntax-parser
[(_ stx)
(define label (gensym 'L))
#`(log-error "at ~a (~a) ; ~a ~a"
'#,label
(quote-srcloc-string #,#'stx)
'#,(current-module-declare-name)
'#,(current-module-declare-source))]))
X is also used in many other macros:
(define-simple-macro (USE)
(void (vector (X 'USE)))) ;; A
(X (or 'here #f))
(X 'there)
(USE) ;; B
(USE) ;; C
It works, but it would be better if (X 'USE) can log information about
its uses at B and C in addition to the source location A for debugging
purpose. If I don't want to change the implementation of USE, is there
a way for X to obtain the source information of B and C?
Currently, the only information I can get is the client module that
uses USE, obtained by checking (current-module-declare-name) at
expansion time in X.
