This mod lets you sync KubeJS scripts for your mod or modpack from a git(hub at current) instance to the Minecraft instance. That probably doesn't need more explaining than that...

It's not hard to setup. For mods: put under /data/<ns>/config/kubejs_sync/repos.json or kubejs/config/kubejs_sync.json for modpacks.

{
  "id": "fee",
  "github": "your-git-name/repo-name",
  "branch": "main",
  "requires": ["modid1"],
  "enabled": true
}

Then in the git(hub) repo. Have this file structure.

packs/<name>/pack.json   # { "requires": ["mekanism"] } as the contents
packs/<name>/startup_scripts/...
packs/<name>/server_scripts/...

Warning!!!: though the mod doesn't execute files downloaded by it, and KubeJS is sandboxed. This may allow for any file type to be grabbed. If there's any future exploit allowing for files to execute on download on your system, please be werry when this mod is used/required. I don't hold responsibility for any malicious use of this mod's syncing feature under GPLv3.

This mod only grabs files under /packs but at current I haven't implemented sanity/file type checks
