Clojure Command Language is a simple turing-complete wrapper for the minecraft command system using the Clojure programming language. This means that you are allowed to use things like variables, loops, conditionals, and more to execute templates of commands

There are two basic commands: /ccl and /cclfile

First is /ccl which provides access to a clojure command line. I don't recommend using this for executing commands though, as it can get quite messy (see last example in this section). Minecraft doesn't allow any slashes in commands beyond the first character, so please use '|' instead and a slash will be substituted back in before evaluation.

/ccl 0
=> 0
/ccl (+ 3 2)
=> 5
/ccl (defn double-it [n] (* 2 n))
=> #'clojure.core/double-it</p>
/ccl (def x 5)
=> #'clojure.core/x</p>
/ccl (double-it x)
=> 10
/ccl (let [y (+ 2 5)] (lib|exec ["say " y]))
=> [playername] 7

The second command is /cclfile which will probably be more useful. Upon first load the mod will create a directory called 'ccl_scripts' in your modpack parent directory (not /config/) where you can put your *.clj scripts. No reloading is required; once you save a file it is ready to use.

If you have a file, let's say, at path /my_modpack/ccl_scripts/sayhi.clj

you would call it by using the command /cclfile sayhi

Here is an example to demonstrate the power of the mod

makeline.clj

(dotimes [x 50]
         (let [meta (mod x 15)]
              (lib/exec ["setblock ~" x " ~0 ~1 wool " meta])))

I recognize that Clojure isn't everyones cup of tea, but at the present I have no intention of changing the language or supporting additional languages.
