Question

This is the second question after Is there a standalone Clojure package within Leiningen?

For example, I have a file hello_world.clj, and I can run it using

java -cp clojure.jar clojure.main hello_world.clj.

Since lein already contains Clojure (because I can run lein repl directly), is there a way to do the same thing like

lein script hello_world.clj by lein?

Answer 1

use lein-exec plugin, example from readme.md (updated with “lein” instead of “lein2”)

cat foo.clj | lein exec
lein exec -e '(println "foo" (+ 20 30))'
lein exec -ep "(use 'foo.bar) (pprint (map baz (range 200)))"
lein exec -p script/run-server.clj -p 8088
lein exec ~/common/delete-logs.clj
