Hook after function?

[Froali]

Hi there,

I'm fairly new to the ESO Ui API and stumbled upon the ZO_PreHook function to take action before some function is processed. Is there an similiar function to take action after some function is finished? I was looking for something like ZO_PostHook, but didn't find anything using zGoo.

Some hints or workarounds would be nice

I think you just have to make your own postHook. Only tested this in the Lua emulator..

foo = function()
	print("Foo")
end

local bar = function()
	print("Bar")
end

local postHook = function(funcName, callback)
	local tmp = _G[funcName]
	_G[funcName] = function()
		tmp()
		callback()
	end
end

postHook("foo", bar)

foo() -- Prints "Foo\nBar"

Thanks! That bit of code did the work. I just had to modify it a little to support a variable amount of parameters:

local postHook = function(funcName, callback)
  local tmp = _G[funcName]
  _G[funcName] = function(...)
    tmp(...)
    callback()
  end
end

Any chance you could give a code example of it in use in the game?

Like, any way to hook the mouse menu that appears when you right click an item in your inventory, or a way to see what 'command' is executed when you select any of those menu options?

Tried to dig through it in Zgoo but couldn't really get very far with it.
