  • user=> (def x [1 2 3 4 5])
    #'user/x
    user=> x
    [1 2 3 4 5]
    
    
    ;; Turn that data into a string...
    user=> (pr-str x)
    "[1 2 3 4 5]"
    
    
    ;; ...and turn that string back into data!
    user=> (read-string (pr-str x))
    [1 2 3 4 5]
    
  • ;; you can think of pr-str as the inverse of read-string
    ;; turn string into symbols
    user=> (read-string "(a b foo :bar)")
    (a b foo :bar)
    
    ;;turn symbols into a string
    user=> (pr-str '(a b foo :bar))
    "(a b foo :bar)"
  • (defn write-object
      "Serializes an object to disk so it can be opened again later.
       Careful: It will overwrite an existing file at file-path."

          (.write wr (pr-str obj)))))
