2x Error loading WTF\Account\KALDARA\SavedVariables\MacroParser-1.0.0.lua

This only occurs on the first execution of the addon with no saved data file yet in existence.

This is my TOC file.

## Author: KaldaraWorks

MP_Initialize.lua
MacroParser.lua

This is the ONLY place where MP_SavedData appears in my code (verified by search).

function f.Initialization()

	local frame									= CreateFrame('Frame')
	frame:RegisterEvent('ADDON_LOADED')
	frame:RegisterEvent('PLAYER_ENTERING_WORLD')
	frame:RegisterEvent('PLAYER_LEAVING_WORLD')
	
	frame:SetScript("OnEvent", function(self, event, ...)
		if     (event == 'ADDON_LOADED') then
			if  MP_SavedData and
				(MP_SavedData.SysEmotesSize or 0) > 0 and
				(MP_SavedData.SysCmdsSize	or 0) > 0 then
				d.SysEmotes						= CopyTable(MP_SavedData.SysEmotes)
				d.SysEmotesSize					= MP_SavedData.SysEmotesSize
				d.SysCmds						= CopyTable(MP_SavedData.SysCmds)
				d.SysCmdsSize					= MP_SavedData.SysCmdsSize
			else
				MP_SavedData					= {}
			end
		elseif (event == 'PLAYER_ENTERING_WORLD') then
			if     MP_SavedData 
			and MP_SavedData.SysCmdsSize	and MP_SavedData.SysCmdsSize	> 0
			and MP_SavedData.SysEmotesSize	and MP_SavedData.SysEmotesSize	> 0 then
				d.AddOnCmds, d.AddOnCmdsSize	= f.GetAddOnCmdsList()
			elseif f.SysCmdsEligible("Initialization") then
				MP_SavedData					= {}
				d.SysEmotes, d.SysEmotesSize	= f.GetEmotesList()
				d.SysCmds  , d.SysCmdsSize		= f.GetSysCmdsList()
				d.AddOnCmds, d.AddOnCmdsSize	= f.GetAddOnCmdsList()
			else
				MP_SavedData					= {}
			end
		elseif (event == 'PLAYER_LEAVING_WORLD') then
			MP_SavedData						= CopyTable(d)
		end
		
	end)

end

If I run it a second time, it works just fine.

I know I could just run it a second time and be done with it but this is going to eventually be a distributed addon and it feels sloppy to have this happen. None of the other addons I have did this on first run and I’d like to get rid of the error.

If you delete your SavedVariables file while logged in and then do a /reload, because it caches these things, the game thinks the file should till exist hence the error.

If you delete your SV file(s), exit the game entirely before re-logging.

Okay, I’ll give that a shot. I was only logging out not exiting the game. I’ll delete the files and come in cold and see if it shows up.

Yup. That did it.

So far it’s doing what it should do. I was just worried about that error but on a fresh install it won’t happen and unless someone actively deletes the saved data it won’t happen either.

Thanks, Fizzy.
