[ACCEPTED]-How to run .clj file as a script using leningen?-leiningen
There are several ways with lein repl:
- Very slow:
cat your_file.clj | lein repl - Slow:
echo '(load-file "your_file.clj")' | lein repl - Fast:
lein repl(load-file "your_file.clj")- repeat

use lein-exec plugin, example from readme.md (updated 1 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
leiningen can create an 'uberjar' for you 11 with all your dependencies....
lein uberjar
will create 10 a jar for you in the target subdirectory. The 9 jar will contain all the dependencies listed 8 in your project.clj, so you don't need to worry about 7 constructing a complex classpath to invoke 6 your code.
You can reference this uberjar 5 as a single entry in your java classpath 4 in the normal way or, specify a main-class 3 in the project.clj invoke it as an executable jar.
e.g. a 2 project.clj like this:
(defproject clj-scratch "1.0.0-SNAPSHOT"
:description "FIXME: write description"
:dependencies [[org.clojure/clojure "1.4.0"]
:main clj-scratch.core)
will invoke the -main function in 1 clj-scratch.core namespace
if you run:
java -jar target/clj-scratch-1.0.0-SNAPSHOT-standalone.jar
I like to use inlein for that.
#!/usr/bin/env inlein
'{:dependencies [[org.clojure/clojure "1.8.0"]
[com.hypirion/primes "0.2.1"]]}
(require '[com.hypirion.primes :as p])
(when-not (first *command-line-args*)
(println "Usage:" (System/getProperty "$0") "prime-number")
(System/exit 1))
(-> (first *command-line-args*)
(Long/parseLong)
(p/get)
println)
Then just chmod +x script.clj and run 1 it!
Alternatively you can just inlein script.clj my args here as well.
