[FeatureRequest] more user friendly lua parsing/execution

[Bia10]

Currently the way that Lua is parsed and executes is kind of confusing:

public void ClickOnTrainButton()
{
   LuaDoString("LoadAddOn\"Blizzard_TrainerUI\"f=ClassTrainerTrainButton;f.e=0;if f:GetScript\"OnUpdate\"then f:SetScript(\"OnUpdate\",nil)else f:SetScript(\"OnUpdate\",function(f,a)f.e=f.e+a;if f.e>.01 then f.e=0;f:Click()end end)end");
}

• Annoyingly long lines, not suitable for diff comparison
• Stripping of whitespace makes it hardly readable
• Need to escape strings from Lua code

Why can't we have it like this?

public void ClickOnTrainButton()
{
	LuaDoString(@"
	LoadAddOn"Blizzard_TrainerUI"
	local trainButton = ClassTrainerTrainButton
	trainButton.e = 0

	if trainButton:GetScript"OnUpdate" then
	   trainButton:SetScript("OnUpdate", nil)
	else
	     trainButton:SetScript("OnUpdate", function(trainButton, e)
	     trainButton.e = trainButton.e + e
		 if trainButton.e > .01 then
		    trainButton.e = 0
	            trainButton:Click()
		 end
	     end)
	end")
}
