Is there a Racket equivalent of Perl's __FILE__ token?
In Perl I can do this:
I'd like to be able to access files at runtime that have a path known in
relation to the current file. I can do this:
(define-runtime-path this-dir ".")
(file-exists? (build-path this-dir (some-func-that-returns-a-path)))
...but that requires the define-runtime-path in any file I want to do this
in.
Is there a built-in version of (define-runtime-path this-dir ".") ?
Alternatively, is there a built-in version of Perl's __FILE__ token, which
gives me the absolute path to the source file in which it is used?
