read-line not working in clojure REPL

Whenever I call a clojure function that gets a users' console input using (read-line) through SLIME or a normal REPL, the function returns immediately. I've resorted to jar'ing up my project and running it to test but this obviously isn't quick or sustainable.

Is there some trick to getting console interaction through a REPL working or is it not possible? If not are there any good workarounds?

Solution

  • This will work now with swank-clojure 1.4.0-SNAPSHOT if you wrap the call to read-line in swank.core/with-read-line-support like this

    (with-read-line-support (println "a line from Emacs:" (read-line))
