@racketmodname[scribble/comment-reader] uses @racket[unsyntax] to
The implementation of @racketmodname[scribble/comment-reader] uses @racket[unsyntax] to
typeset comments. When using @racketmodname[scribble/comment-reader]
with, for instance, @racket[RACKETBLOCK], which specifies
@racket[UNSYNTAX] as @racket[escape-id], this causes problems. You can
pass a new @racket[escape-id] for
@racketmodname[scribble/comment-reader] by using @racket[#:escape-id]:
with, for instance, @racket[RACKETBLOCK], @racket[unsyntax] does not escape,
since @racket[RACKETBLOCK] uses @racket[UNSYNTAX] as its escape form. You can
declare an escape identifier for
@racketmodname[scribble/comment-reader] with @racket[#:escape-id]. For example,
@verbatim[#:indent 2]|{
@#reader scribble/comment-reader #:escape-id UNSYNTAX
(RACKETBLOCK
(define-syntax (m syn)
(syntax-case syn ()
(define-syntax (m stx)
(syntax-case stx ()
[(_ x)
;; Well this was silly
#`(#,x)]))
