Creating my own datapack was pretty straightforward once I figured out the directory structure. I needed to put functions in <world-name>/datapacks/sachac/data/sachac/functions. Inside <world-name>/datapacks/sachac, I created pack.mcmeta with the following contents:

{
    "pack": {
        "pack_format": 10,
        "description": "sachac's tweaks"
    }
}

Inside <world-name>/datapacks/sachac/data/sachac/functions, I created a command_book.mcfunction file with the command to give me the book. I updated my command book function to remove the / from the beginning.

I used /reload to reload my Minecraft configuration and /datapack list to confirm that my datapack was loaded. Then /function sachac:command_book ran the function to give me the command book, so that all worked out. I replaced the command in the command block with the function call.

The next step was to update it directly from Emacs, including reloading. First, I needed a function to give me the filename of a function file.

(defun my-minecraft-datapack-function-file-name (world datapack-name function-name)
  "Return the filename for a mcfunction file given WORLD, DATAPACK-NAME, and FUNCTION-NAME."
  (seq-reduce
   (lambda (path subdir) (expand-file-name subdir path))
   (list "datapacks"
         datapack-name
         "data"
         datapack-name
         "functions"
         (concat function-name ".mcfunction"))
   world))

I used C-c C-x p (org-set-property) to add a WORLD property to my Org subtree. For example, my snapshot world is at /ssh:desktop:~/.minecraft/saves/Snapshot. Then I can get the correct value within the subtree by using org-entry-get-with-inheritance. This is how I wrote the command book function for my snapshot world:

#+begin_src emacs-lisp :var body=mc-snapshot :var team=mc-team :var quick=mc-quick :var effects=mc-effects :var items=mc-items :results silent
(with-temp-file
    (my-minecraft-datapack-function-file-name
     (org-entry-get-with-inheritance "WORLD")
     "sachac"
     "command_book")
  (insert (my-minecraft-book "Commands 8.5" "Mom" (append team quick body effects items))))
(mcf-eval "reload")
#+end_src

So now I can use C-c C-c to execute the Emacs Lisp block and have my Minecraft world updated. Then I just need to right-click on my command block's button or run the function in order to get the new version.

I'm looking forward to learning more about mcfunctions so that I can write a function that automatically replaces the book in everyone's inventories. Could be fun.
