Yes, the path separator is O/S dependent: user> (import '(java.io File)) java.io.File user> (reduce #(File. %1 %2) ["one" "two" ".." "three"]) #<File one/two/../three> user> (.getCanonicalFile (reduce #(File. %1 %2) ["one" "two" ".." "three"])) #<File /Developer/workspace/worldsingles/ws/model/clojure/worldsingles/one/three> user> (.getPath (reduce #(File. %1 %2) ["one" "two" ".." "three"])) "one/two/../three"
Note that .getCanonicalFile renders the file path relative to the directory in which the REPL's JVM instance was started.
