Scripting with Ba·bash·ka

Babashka is a native, stand-alone Clojure interpreter built for scripting - https://github.com/babashka/babashka

This is the time it takes to run a simple script from JMV/Clojure:

	./toycalc.clj  4.49s user 0.15s system 295% cpu 1.569 total

This is the same script in Babashka:

	./toycalc.bb  0.43s user 0.04s system 74% cpu 0.484 total

'nuff said, right?

Differences

• In the sample script, we import libraries (including cli-matic) right from the script itself, so you can have single-file scripts. As an alternative, for example if you have multiple scripts with the same deps and you don't want to change them all when you upgrade a library, you can to have a bb.edn file with the libraries you need. Look at the example_bb.edn file here for a minimal working solution.
• You do not need an external namespace, but you can simply (require '[cli-matic.core :refer [run-cmd]])
• You don't need a main function, but you just call (run-cmd *command-line-args* CONFIGURATION)

Good luck!
