(ns rrs.io-helpers
(:import
(java.io FileWriter
BufferedWriter)))
(defmacro dcmfail
[]
`(BufferedWriter. (FileWriter. "stand-back")))
(defmacro ncmsucceed
[]
`(new BufferedWriter (new FileWriter "careful")))
(defn dcsucceed
[]
(BufferedWriter. (FileWriter. "watch-out")))
user=> (dcmfail)
java.lang.IllegalArgumentException: Unable to resolve classname:
BufferedWriter (repl-1:2)
user=> (ncmsucceed)
#<BufferedWriter java.io.bufferedwri...@a9255c>
user=> (dcsucceed)
#<BufferedWriter java.io.bufferedwri...@193f6e2>
Following the test, "careful" and "watch-out" exist, "stand-back" does
not.
