Clojure Command Language

The Clojure Command Language mod provides a versatile wrapper that extends the capabilities of Minecraft's standard command system by implementing the full-featured Clojure programming language. This solution is Turing-complete, allowing Minecraft commands to utilize programming elements such as variables, loops, conditional statements, and other structures for executing command templates.

Main Commands

The mod adds two key commands: /ccl and /cclfile.

/ccl Command

This command provides access to an interactive command line operating on Clojure. However, for executing complex scenarios, its use is not recommended - the file-based approach is preferable. Minecraft imposes restrictions on the use of slashes in commands, so instead of direct slashes, the '|' symbol should be used, which will be automatically converted before execution.

/cclfile Command

This tool proves much more practical in use. Upon first mod launch, a 'ccl_scripts' folder is automatically created in your modpack's root directory (not inside /config/), where you can place scripts with *.clj extension. The advantage is that after saving a file, it immediately becomes available for use - no reloading is required.

To execute a file located at path /my_modpack/ccl_scripts/sayhi.clj, simply enter the command /cclfile sayhi.

Practical Example

Consider the makeline.clj script demonstrating the mod's capabilities:

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

The author acknowledges that Clojure may not suit all users, but currently, there are no plans to change the programming language or add support for other languages.
