I need help debugging this please

[MigGat]

Hi all,


I wrote a really simple addon with autoresponses to whisper. There are some filters to select different automessage but that's not the point.

The problem is that when I recieve a whisper (and the addon is active), game almost freeze. Fps drops to 2, and addon memory usage goes from 63MB to 80MB.

So it looks like and endless loop or something, but I can't find it. Is there any tool I could use to debug? With breakpoints and that stuff... (i guess no).

Or maybe can you see anything wrong in this code?

This function is called when a whisper is recieved:

function evAYChatWhisp(sender, msg)	
	isinstance, instancetype = IsInInstance();
	if fixedMsgEnabled==true then 
		SendChatMessage("Automessage: " .. parseAYMessage(FixedMsgText), "WHISPER", nil, sender);
	elseif -- Not relevant code
end

This function is called from the previous function:

function parseAYMessage(msg, sender)
	instancenamename, type, difficulty = GetInstanceInfo()

	if string.find(msg, "@user") == nil then else
		msg = string.gsub(msg, "@user", sender);
	end
	
	if string.find(msg, "@instance") == nil then else
		msg = string.gsub(msg, "@instance", instancenamename);
	end
	
	return msg;
end

Your current code doesn't show anything that could cause a freeze - please post your full code. (maybe via pastey.net)

By the way:
if string.find(msg, "@instance") == nil then else
is better written as:
if string.find(msg, "@instance") then

I never encountered a "then else" without anything in between

You are also missing "local" before your "isinstance"- and "instancenamename"-variables.

What caused the freeze was GetInstanceInfo() function while I was OUTSIDE any instance :S

I expected to get a nil, not this but.. it's solved now.

As for

if string.find(msg, "@instance") == nil then else is better written as: if string.find(msg, "@instance") then

Are oposite things :P I didn't find a "not-equal operator" it is "!=" maybe?

I'm really confused with lua, as I always use c# at work.. :S

Not equal is ~= or you can put "if not string.find" for example.

You seem to be only feeding your function parseAYMessage() with one parameter yet it's not coded to check if both are set or not ?

Thanks! Argument error fired when I solved the GetInstanceInfo() thing, and now it's working just fine.

Thank you all again
