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.

What's that?

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.

fire works with clj, lein-exec and babashka.

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