v2.0-beta4

Whats changed

• Improved error handling
• New method (LuaAPI/LuaCoroutine).set_hook this allows you to set a Callable as a lua hook. See example below.
• New method LuaAPI.get_running_thread. As the name implies this method returns the coroutine which is currently running. Intended to be called from a hook.
• New method LuaCoroutine.yield_state As the name implies this method yields the coroutine state. Intended to be called from a hook.
• LuaJIT support for gdExtension (only Linux, Windows and MacOS for now)

Hook code example:

extends Node2D

var lua: LuaAPI
var coroutine: LuaCoroutine

func _lua_hook(lua: LuaAPI, event: int, line: int):
	var co: LuaCoroutine = lua.get_running_coroutine()
	co.yield_state([1])

func _ready():
	lua = LuaAPI.new()
	# Despite the name, this is not like a OS coroutine. It is a coroutine.
	coroutine = lua.new_coroutine()
	coroutine.set_hook(_lua_hook, LuaAPI.HOOK_MASK_COUNT, 4)
	coroutine.load_string("
	while true do
		print('Hello world!')
	end
	")

var yieldTime = 0
var timeSince = 0
var goodBye = false
func _process(delta):
	
	timeSince += delta
	# If the coroutine has finished executing or if not enough time has passed, do not resume the coroutine.
	if coroutine.is_done() || timeSince <= yieldTime:
		if !goodBye:
			lua.do_string("""
			for i = 0,10,1 do 
				print('Good Bye World!')
			end
			""")
			goodBye=true
		return
	goodBye=false
	# coroutine.resume will either return a LuaError or an Array.
	var ret = coroutine.resume()
	if ret is LuaError:
		print("ERROR %d: " % ret.type + ret.message)
		return
	# Assumes the user will always pass the number of seconds to pause the coroutine for.
	yieldTime = ret[0]
	timeSince = 0
