Making Clojure App Finalize Leiningen Setup and Get a Clojure Build Hello-World App First, make the Target Folder: mkdir $HOME/Documents/Clojure&&cd $HOME/Documents/Clojure And then Create it: lein new myapp The Command First, Finalize Leiningen Installation and then Create a Skeleton of a simple Clojure App... The Core of the App is in the myapp/src/myapp/core.cli File. Default content: (ns myapp.core) (defn foo"I don't do a whole lot." (println x "Hello, World!")) Note that the Namespace declaration Matches the Folder Structure. Since the core namespace is inside the myapp folder, its name is myapp.core. 4. Editing Clojure App Then Specify a Namespace in the project.cli File to Make a Working App Access the Target: cd myapp And then Edit it: (Here for simplicity with the nano Editor, but you can just use Anyone.) nano project.cli For example, we could Set the foo Function from the myapp.core namespace as the Entry Point for the application Using the :main Key like: (defproject myapp "0.1.0-SNAPSHOT" :description "FIXME: write description" :url "http://example.com/FIXME" :license {:name "Eclipse Public License" :url "http://www.eclipse.org/legal/epl-v10.html"} :dependencies ] ;;this will set foo as the main function :main myapp.core/foo) Ctrl+x to Save & Exit from nano Editor :) 5. Running Clojure App The you can Run the Clojure Hello-World App With: lein run Happy That will Return as Output: Happy Hello, World!
