I’m trying to validate emails, but I can not understand very well how regular exepression works in godot, I’m getting an error in the “.compile” lines, am I forgetting to escape some character?

func validate_email(email):
    	var exclude = RegEx.new()
    	var check = RegEx.new()
    	var checkend = RegEx.new()
    	exclude.compile("[^@-.w]|^[_@.-]|[._-]{2}|[@.]{2}|(@)[^@]*1")
    	check.compile("@[w-]+.")
    	checkend.compile(".[a-zA-Z]{2,3}$")
    	if exclude.search(email) != null || check.search(email) != null || checkend.search(email) != null:
    		return false
    	else:
    		return true
