clojure-fire

This makes it easy to create and run CLI tools in Clojure without any configuration.
The idea and name are coming from python-fire.

How does it work?

Let's say you have a function to run via -main,

(defn multiply
  [x y & more]
  (apply * (concat [x y] more))

(defn -main
  [& args]
  ;; call multiply
)

How do you handle args?
Just parsing it by hand? or using tools.cli?
Fine, there's no problem.

With fire, you can call the function like this.

(defn -main
  [& args]
  (fire))

and run it on a command line.

$ bb -m <path to file> multiply 2 3 ;; or "clj -m <path to file> ..."
6

So, all you need to do is just calling (fire) in your program and run it with a function name and args on a command line. Then fire finds the target function and calls it with the given arguments. You don't need any configuration.

More details are found on wiki.

fire works with clj, lein-exec and babashka.

Tested on Mac, should work on Linux.
Sorry, but not sure with Windows.
