Use a Datomic archive for clojure REPL

Now clojure's latest stable version is 1.4.0, and 1.5.0-RC4 is as a beta.

They have a REPL (Read-Eval-Print-Loop) environment, but it's a bit poor because of no history, complement and edit feature.

I planned to add the features to the REPL and found a good library jline2 which supports all functions I want.

When I built a set of projects for the both on my eclipse, I found a new good one which already has great editable REPL environtment for clojure. It's Datomic, which is a one of database products which has new architecture. (This is very interesting for me! I'll check this later!)

Download a free version from here, extract it and change current directory. You can see repl-jline in the bin directory.

$ ./bin/repl-jline
Clojure 1.4.0

Congraturation!
you got very useful REPL environment!
