Not datomic but Leiningen for REPL

February 2, 2013

I described Datomic provides a better REPL which we can use command history and line-edit in.

Actually, I found a new better one, leiningen. It's a build & package manager like maven of Java.

The way to install is very easy according to its README.

$ mkdir -p ~/bin
$ PATH=$PATH:~/bin
$ wget -O ~/bin/lein https://raw.github.com/technomancy/leiningen/stable/bin/lein
$ chmod +x ~/bin/lein
$ lein

Just only!

And type to run REPL just like this, lein repl.

$ lein repl
nREPL server started on port 51856
REPL-y 0.1.9
Clojure 1.4.0
    Exit: Control+D or (exit) or (quit)
Commands: (user/help)
    Docs: (doc function-name-here)
          (find-doc "part-of-name-here")
  Source: (source function-name-here)
          (user/sourcery function-name-here)
 Javadoc: (javadoc java-object-or-class-here)
Examples from clojuredocs.org: [clojuredocs or cdoc]
          (user/clojuredocs name-here)
          (user/clojuredocs "ns-here" "name-here")

In REPL, you can use command-history, line-edit and command-complement. Command-complement is not supported in the REPL of datomic. Super wonderful!

Let's enjoy clojure life!
