Hook into Filter Change

Any way I could have a script execute anytime the At filter changes?

So I think I answered my own question, here is where I arrived at the moment.

I noticed that the callback runs twice each filter change so added this runonce expression to get around that.

local my_handle = select(4,...);

local function main()

local runonce = y

local hookObject = CurrentEnvironment().AtFilter

local pluginHandle = my_handle:Parent();

local callbackFunction = function(obj)

if runonce == "y" then

FilterName = tostring(CurrentEnvironment().AtFilter.FilterRef.Name)

Printf(FilterName)

runonce = "n"

else

runonce = "y"

end

end

HookObjectChange(callbackFunction, hookObject, pluginHandle)

end

return main
