Install Clojure

As of , current Clojure version is 1.8

Unpack it, by tar xvfz filename.

For example, after unpacking, i have this file clojure-1.8.0.jar.

Start Clojure REPL

Clojure REPL

Start Clojure like this:

# start clojure repl
java -cp /home/xah/clojure-1.8.0.jar clojure.main

(make sure the Clojure jar file path above is where you have it)

To make it convenient, set a alias in your ~/.bashrc, like this:

alias clojure="java -cp /home/xah/.m2/repository/org/clojure/clojure/1.8.0/clojure-1.8.0.jar clojure.main"

Now you can start Clojure REPL by just typing “clojure”.

[see Bash Init, .bashrc .profile .bash_profile]

(REPL = “Read Eval Print Loop”. It is a command line interface, like bash.)
