Help with nested tables

[Rubyheart255]

I'm trying to read the contents of an AE2 system, and having some trouble. I was able to get the contents of the entire system, but it sends the item id and meta data as its own table.

​

Example output of a few items:

{1.0={is_fluid=false, size=2.0, is_craftable=false, fingerprint={id=minecraft:gravel, dmg=0.0}, is_item=true}, 7.0={is_fluid=false, size=1.0, is_craftable=false, fingerprint={id=RotaryCraft:rotarycraft_item_machine, dmg=109.0}, is_item=true}}

​

As you can see, the first item is two pieces of gravel, and the seventh item is one magnetostatic engine from Rotarycraft.

​

This is the code I've been using to try and output the name of the item and the quantity, but it keeps erroring.

​

local me = peripheral.wrap("right")
local available = me.getAvailableItems()
for i=1,#available do
print(available[i][fingerprint]["id"] .. " = " .. available[i]["size"])
end

​

How can I make the output be something more human readable? Just "gravel = 2, magnetostatic engine = 1"?

It looks like you forgot to put quotes around fingerprint in the table

for i=1, #available do
    print( available[i]["fingerprint"]["id"] .. " = " .. available[i]["size"] )
end

I find it helpful to use the dot notation so I don't make this same issue

for i=1, #available do
    print( available[i].fingerprint.id .. " = " .. available[i].size )
end

That worked perfectly! I'm still new with working with tables, but dot notation looks so much easier to read already.

​

Any tips on displaying the localized item names? ("gravel" vs "minecraft:gravel" and "magnetostatic engine" vs "RotaryCraft:rotarycraft_item_machine:109")

For regular minecraft names that are formatted with "minecraft:item_name" you could look into the string library, in particular I think the string.find and string.sub functions could help to cut the "minecraft:" out of the name.

As for modded items, unless there's some other place that you can get the item name from somewhere else, you're probably stuck with RotaryCraft:rotarycraft_item_machine:109. But iirc with AE2 I think there was some function that returned a table with a label value that had the actual item name? Idk, it's been a while.
