User:Fleeting Frames/itemage

Tested in 43.03 only at present. Usage as console command requires only adding the bottom code chunk on this page into itemage.lua file as text, then selecting an item and typing itemage into console or typing itemage itemid into console (where itemid is number given by item's id).

Usage as dwarfmonitor plugin needs these additional steps at present:

1. Add the line

pcall(function() Widget_itemage = dfhack.script_environment('itemage').Widget_itemage end)

into /hack/lua/plugins/dwarfmonitor.lua on an empty line somewhere before the return _ENV line on newline near the very end. 2. Add

		,{
		"memory": true,
		"type": "itemage",
		"x": -17,
		"y": 2
	}

Into dfhack-config/dwarfmonitor.json after the last widget.

Either way, you need the below in itemage.lua to have it work:

--Prints the selected item age or provided age
--Or provides a widget for dwarfmonitor

--TODO toggle enable/disable on click while displaying

--[[

		{
		"memory": false,
		"type": "itemage",
		"x": -17,
		"y": 2
	},

]]
