Hi --
Thanks so much, Laurent!
I was actually kind of close (you told me not to peep, so I didn't hehe).
(defn pt30 [file]
(def ^:dynamic *asb* (StringBuilder.))
(let [afr (FileReader. file)
bfr (BufferedReader. afr)]
(loop [x (.read bfr)
*asb* (StringBuilder.)]
(when (not (= x -1))
(recur (.read bfr) (.append *asb* (java.lang.Character/toChars
x)))))))
with (def ribs "/path/to/ribs.txt")
which looks similar. But, for some reason, the *asb* variable didn't
populate with rib advertisements:
user> (pt30 ribs)
nil
user> *asb*
#object[java.lang.StringBuilder 0x29f4eb0c ""]
When I convert this practically to the same you did,
user> (defn pt34 [file]
(let [afr (FileReader. file)
bfr (BufferedReader. afr)]
(loop [x (.read bfr)
sb (StringBuilder.)]
(if (not (= x -1))
(.toString sb1)
(recur (.read bfr) (.append sb (char x)))))))
#'user/pt34
user> (pt34 ribs)
""
I still get no beef (err, ribs). Doesn't print anything either.
Weird. Just weird.
