Defining item stack with a one-liner. Keep in mind that it should not contain any spaces, and in case you need to define space for something like item name or item lore, use an underscore like _ and in case you need an actual underscore, then use double, like __
Examples of more complicated items
diamondsword;{#Gray}My_Uber_Sword;&2Goblin_Slayer!\n{#pink}With_Love!;sharpness:3,durability:3;hideenchants
bow;AttackDamage:1.5:multiply_base:Mainhand,Luck:1:multiply_base:Head;unbreakable;hideunbreakable
leatherchestplate;#pink;Redstone:Coast
Material
Item definition needs to start with a material name. For example snowball or SNOWBALL or even SNOW_BALL will be accepted.
Sub values
Sub-values are separated with ; followed with an indicator to define what type it is, and its value is enclosed with {}. If you need ; inside a name or lore, then use ;;
No spaces allowed; use _ for space and __ for underscore.
Amount
Amount is defined after material by separating material name with -, for example, ACACIA_PRESSURE_PLATE-5 which will define 5 items. If the amount is not defined then 1 will be used.
Alternatively, you can separate the amount with ; like ACACIA_PRESSURE_PLATE;5
Item Name
The item name is defined as n{&2Custom_Item_Name} or clean &2Custom_Item_Name if this is the first entry as a text that can’t be recognized as any other variable, ignored if it contains \n, which will be used for lore entry instead
Example: BREAD-12;&2Tasty! or BREAD-12;n{&2Tasty_food!}
Item Lore
Item lore is defined as l{&2First_Line\n&3Second_line} or clean &2First_Line\n&3Second_lineseparate lore lines can be defined by including \n, no empty spaces in it. If it is a single line, then it will need to be enclosed with l{} or have an item name already defined before it.
For example: BREAD-12;l{&2Eat_Me!} or BREAD-12;&2Eat_Me!\n{#blue}Tasty!
Enchants
Item enchants are defined as sharpness:2,durability:5 separate enchants if you want to include more than one.
Example: Bow;durability:5,power:1
Custom Model Data
Item custom model data is defined as cm{123456} this needs to contain an integer-type number
Example: carrot;cm{1234}
Attributes
Item attributes are defined as AttackDamage:1.5:add:Mainhand,Luck:1:multiply_base:Head the first value will define the attribute type, followed by the amount it needs to change. This can be any fractional value that will be used in a defined operation. The operation can be defined by numbers 0, 1, 2 or by operation names add, multiply_base, multiply

Spawner type
It is only applicable for spawners. Spawner type can be defined in a basic way as creeper or any other entity type existing in your server version.
Side note: setting the spawner name will change the spawner’s custom name, and if you are defining items’ custom name without using n{[name]} format, then you should set the name before setting the spawner name; the name will be shifted into the lore section.
