First start up the REPL by issuing this command:

clj -Sdeps '{:deps {github-mfikes/e00202b2de7cc2352fedcf92b1fe60dc {:git/url "https://gist.github.com/mfikes/e00202b2de7cc2352fedcf92b1fe60dc" :sha "c18479fa4fdf4bb2af3d971cb1aaeb2cbd8c909c"}}}' -m cljs.main -i @index.cljs -r

Once the REPL is waiting for the browser to connect, if it doesn't automatically, open http://localhost:9000 in your browser.

You will now be running Bocko. The following forms evaluated in the REPL will draw an American flag.

#Array Flattener

The main program file is flatarray.rb, in order to run it you can simply, require_relative 'flatarray' in irband then call the program as follows :

m = FlatArray.new([[1,2,[3]],4, [5,6,[7,8],[9]]]) And then execute m.squash

Two gentlemen and their rant on languages.

Rant

• Racket & scheme are orders of magnitude faster than clojure.
• I like lisp but I hate this clojure movement. Especially when 60% of it is written in Java.
• Are there major java libraries for which there is no scheme implementations?
• Why did people pick up clojure rather than racket. Hype?

Sorry, I have to disagree with the entire premise here.
