The signature for build-path/convention-type is: (build-path/convention-type type base sub ...) → path-for-some-system?
type : (or/c 'unix 'windows) base : (or/c path-string? path-for-some-system? 'up 'same) sub : (or/c (and/c (or/c path-string? path-for-some-system?) (not/c complete-path?)) (or/c 'up 'same)) I'm running on OSX 10.11.6 (El Capitan) and I don't understand the results I'm getting: -> (define p "C:\\foo\\bar") -> (build-path p) #<path:C:\foo\bar> ; NB: This is *not* a windows path, despite looking like one -> (build-path/convention-type 'windows 'up 'up) #<windows-path:..\..> ; NB: this is a Windows path -> (build-path/convention-type 'windows p) ; build-path/convention-type: specified convention incompatible with string ; path element ; path element: "C:\\foo\\bar" ; convention: 'windows ; [,bt for context] -> (build-path/convention-type 'windows "/foo/bar") (build-path/convention-type 'windows "/foo/bar") ; build-path/convention-type: specified convention incompatible with string ; path element ; path element: "/foo/bar" ; convention: 'windows ; [,bt for context] What gives? Also, while we're at it, what do REL and RED stand for in the docs? https://docs.racket-lang.org/reference/windowspaths.html -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
