[UTIL] Inventory to String/File

Hey Guys!
JHG0 here with a very requested, long awaited, inventory to string parser
I spent hours upon hours getting everything to work.
This supports PlayerInventories, Inventories, and DoubleChestInventories (Cast to Inventory)
This doesn't currently support Enchanted Books, Written Books, Book and Quills, or Fireworks
Feel free to use it in all your plugins : )


Registration
In the Main Class

Code:

public Parser par;

In the onEnable()

Code:

par = new Parser(this.getDescription().getName());

Calling on the parser
Note: Anything in CAPS is something that you choose; Don't forget file extensions!

Code:

par.parsePlayerInventory(FOLDER, FILE NAME, PLAYER INVENTORY);
par.unparsePlayerInventory(FOLDER, FILE NAME, PLAYER INVENTORY);
par.parseInventory(FOLDER, FILE NAME, INVENTORY);
par.unparseInventory(FOLDER, FILE NAME, INVENTORY);

JHG0 Did you even know that ItemStack implements ConfigurationSerializable which allows you to save it to the config with CONFIG.set(PATH, ITEMSTACK) and get it from the config with CONFIG.getItemStack(PATH)? (These methods can be used for every kind of item and it also saves the meta of the item)

Thanks for making me feel bad
Jk

 

JHG0 Sorry, I just wanted to let you know that

 

DarkBladee12 No, you make a good point. Bukkit's built-in methods need more recognition. When you find things I think are missing from the Bukkit API, making a pull request is always a great option.

 

At least he tried his best. I will try to make this better and post some code with a better version.

 

Removed flaming and useless posts.
If you think a tutorial is not good, explain why, attacking the OP however is not acceptable and will net you a warning.

Necrodoom
Thanks.
