### Serialized
This is called "stackstring" or "itemstring". It is a simple string with
1-3 components: the full item identifier, an optional amount and an optional
wear value. Syntax:
1-4 components:
<identifier> [<amount>[ <wear>]]
1. Full item identifier ("item name")
2. Optional amount
3. Optional wear value
4. Optional item metadata
Syntax:
<identifier> [<amount>[ <wear>[ <metadata>]]]

* `"default:dirt 5"`: 5 dirt
* `"default:pick_stone"`: a new stone pickaxe
* `"default:pick_wood 1 21323"`: a wooden pickaxe, ca. 1/3 worn out
* `[[default:pick_wood 1 21323 "\u0001description\u0002My worn out pick\u0003"]]`:
* a wooden pickaxe from the `default` mod,
* amount must be 1 (pickaxe is a tool), ca. 1/3 worn out (it's a tool),
* with the `description` field set to `"My worn out pick"` in its metadata
* `[[default:dirt 5 0 "\u0001description\u0002Special dirt\u0003"]]`:
* analogeous to the above example
* note how the wear is set to `0` as dirt is not a tool
You should ideally use the `ItemStack` format to build complex item strings
(especially if they use item metadata)
without relying on the serialization format. Example:
local stack = ItemStack("default:pick_wood")
stack:set_wear(21323)
stack:get_meta():set_string("description", "My worn out pick")
local itemstring = stack:to_string()
Additionally the methods `minetest.itemstring_with_palette(item, palette_index)`
and `minetest.itemstring_with_color(item, colorstring)` may be used to create
item strings encoding color information in their metadata.
