clojure lein (read-line) stdin woes

Question

So regular clojure repl works fine, (read-line) collects input, then echos it. Using lein repl though, never echoes any input characters, nor does it ever allows me to return from any stdin reading commands.

I'm sure it has something to do with rebinding in, but was wondering if there is a workaround/fix?

Thanks.

Answer 1

Connect to the REPL via telnet.

$ lein repl
REPL started; server listening on localhost:63849.
user=> 
[1]+  Stopped                 lein repl
$ telnet localhost 63849
Trying ::1...
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
user=> (read-line)
hello
"hello"
user=>

This is due to a bug in ant; it prevents the stdin stream from the subprocess it launches from being used. But the telnet trick should work since lein repl launches a socket repl server; it works fine here.
