Question

say i create a program in clojure and i have to deliver it to a client. the client does have some computer knowledge but he does not know/want to start the repl, load my program, and run it. he wants to double click an exe file or run a shell script

how do i package my program and deliver (the program itself with the clojure jars) ?

Answer 1

You have a few choices:

• Compile the program into Java classes, and give one a main method. Package them into an executable jar.
• Per above, if you use Leiningen then you can assemble everything nicely with lein uberjar, making sure that you have declared a main class.
• You can alternately package your project into a non-executable jar (no main class) and create a shell script/batch file to execute the proper class e.g. java -cp ./clojure.jar:./myprogram.jar com.my.runthis.class
• Just package your .clj files into a jar, and use a shell/batch script to start a repl and then automatically issue commands e.g. java -cp ./clojure.jar:./myprogram.jar clojure.main -e "(in-ns 'your-ns)(start-your-program)" -r
