Question

I’m using rlwrap, but I don’t have tab-completion, and characters with accents get mangled. This is on OSX 10.6 in Terminal.app.

Answer 1

Use the -f flag to rlwrap to enable tab completion. It’s going to be static completion though, based on a static list of symbols in some file you specify. If you want dynamic completion (based on any symbol that’s currently defined in your running REPL), you should try Emacs + SLIME or equivalent.

In any case, here’s one way to generate a list of symbols to tab-complete. You will have to regenerate this file from time to time because new symbols are added to Clojure’s core in every version. (This code works with bleeding edge clojure-contrib; clojure.contrib.io was called duck-streams in earlier versions.)

user> (use 'clojure.contrib.io)
nil
user> (with-out-writer "/home/user/.clj-tabcompletion"
        (doseq [[sym _] (ns-publics 'clojure.core)]
          (println sym)))
nil

Then:

$ rlwrap -f ~/.clj-tabcompletion java -jar clojure.jar
Clojure 1.2.0-master-SNAPSHOT
user=> def<TAB>
definline    defmacro     defmethod    defmulti     defn         defonce      defprotocol  defstruct    deftype
user=> def

If your terminal is mangling characters with accents, you likely have an encoding or locale problem. It works fine for me. I don’t use OS X and don’t know what terminal you use, so I can’t help. In Konsole in Linux, inside rlwrap:

user=> (println "àèìòùáéíóúäëïöüâêîôûãõñ")
àèìòùáéíóúäëïöüâêîôûãõñ
nil
user=> (println "牛が牧場で草を食べている。")
牛が牧場で草を食べている。
nil
