mt-api

Type definitions for using the minetest API

using

Install dev dependency in your typescript project:

npm i @repcomm/mt-api --save-dev

And use:

import type {} from "@repcomm/mt-api";

The module declares the minetest global the same way you'd use it in lua
you can also utilize the types it provides in your own code by importing them:

import type { MtVec3 } from "@repcomm/mt-api";

let myVec: MtVec3 = { x: 0, y: 0, z: 0 };

implemented

  • minetest global namespace
minetest.register_on_joinplayer( (player)=>{
  let playername = player:get_player_name();

  minetest.chat_send_player(playername, "Welcome!")
} );

Users of minetest's lua api will noticed a lack of ":" in typescript

Lua uses obj:method and obj.func to differentiate with obj is passed as self as the first argument

For instance:

local obj = {
  method = function (self)
    --"self" refers to obj, similar to "this" in typescript
  end

  func = function ()
    --no self variable here
  end
};

obj.method() -- self will be nil
obj:method() -- self will be obj

obj.func() -- self will be nil
obj:func() -- self will still be nil because its not declared in function args

In typescript this is handled by providing a this definition:

interface MinetestGlobal {
  register_on_joinplayer (this: void, cb: MtPlayerJoinCallback): void;
}
declare global minetest: MinetestGlobal;

Because

this: void

TypeScript calls to minetest.register_on_joinplayer() will properly output: minetest.register_on_joinplayer() in lua

Without providing this: void, this would generate: minetest:register_on_joinplayer() as typescript-to-lua compiler assumes we want to provide a self reference as first argument

On the flip-side:

function handle_player_join (player) --player is ObjRef
  player:get_player_name() -- passes player as first arg to get_player_name code
end

minetest.register_on_joinplayer ( handle_player_join )

In typescript definitions:

interface ObjRef {
  //implicit this: ObjRef
  get_player_name(): string;
  //same as
  get_player_name(this: ObjRef): string;
}

Which both properly output:

player:get_player_name()
