'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= ::eof %)
(repeatedly #(read pbr false ::eof))))))
(read-all "/some/clojure/file.clj")
=> ((foo :bar) (baz))
