'read' and 'read-string' are what you're looking for. They each read a
single Clojure object from an input source (PushbackReader for read,
String for read-string).

Alternatively, something like this can read all top-level forms from a
file:

(defn read-all
  "Reads all top-level forms from f, which will be coerced by
  clojure.java.io/reader into a suitable input source. Not lazy."
  [f]
  (with-open [pbr (java.io.PushbackReader. (clojure.java.io/reader
f))]
    (doall
     (take-while
      #(not=3D ::eof %)
      (repeatedly #(read pbr false ::eof))))))

(read-all "/some/clojure/file.clj")
=3D> ((foo :bar) (baz))
