Let's set up clojure and run our first clojure program.

Download Clojure

Follow this official guide to install the clj and clojure binaries. For now we just need those 2. Once you're all done, come back and lets move on to the next section.

Running our first program

Let's create an empty directory to hold all our clojure source code

mkdir hello-world
cd hello-world
mkdir src
touch hello.clj

hello.clj

(ns hello)

(defn run [opts]
  (print "Hello from Clojure!"))

Finally run this command from the root of the hello-world directory clj -X hello/run

You should see the output: Hello from Clojure!

Congratulations on running your first Clojure program!
