create_recipe(name, content, datapack?, zipped?)
Add functions to add a new recipe/loot_table with the specified name and content (from a map*).
by default it will be generated in the script_name unzipped datapack, but it is possible to change it.

*example of map:

{
  'type' -> 'minecraft:smithing',
  'base' -> {
    'item' -> 'minecraft:deepslate_coal_ore'
  },
  'addition' -> {
    'item' -> 'minecraft:stone'
  },
  'result' -> {
    'item' -> 'minecraft:coal_ore'
  }
}

isn't that only a wrapper around a datapack? This is why I removed 'custom_dimension' since it is just a datapack? Trying to be more generic here.

nah...

suggesting updating the docs to include an example recipe and loottable modification instead of adding a function. Do you have a good examples of such?

I'll make a pool request this evening 😉
