NBTLib

NBTLib

NBTLib provides:

A convenient way to do everything you want with NBT data
Access to Minecraft/Craftbukkit code without having to import the "evil" classes (=> won't break on MC update)

The downside:

You have to catch lots of Exceptions.

If you're interested in NBT data handling, check the javadoc of the "NBT" and "Tag" classes.
If you're interested in accessing MC/CB code, check the javadoc of the NBTLib class.

Installation

Just drop the NBTLib.jar in your plugins folder.

ToDo

Write an NBT editor GUI

No problem, no worries. I completely understand, I've been there, with little free time.
It would be nice if you could post your progress as soon as you get a chance to work on it again. Other than that, take your time.

I'm sorry to say this, but I have to postpone this yet again. Some personal responsibilities came up, limiting my free time. I'm also going to be away from next Wednesday on for two and a half weeks, so I'm not gonna be able to get back to this soon. I'm really sorry. :/

Haha, I'm glad somebody actually uses this plugin. ^^
Making it compatible with MCPC turned out to be impossible to implement while keeping the current API, so I decided to rewrite it. I didn't finish that though, because I had finals I needed to pass and because of all the problems I had with VirtualPack lately (migration to UUIDs).
What I still have to do is rewrite the ClassProxy class and make my reflection classes understand the MCPC mapping files. It's the next thing I'll work on and I hope I'll have it ready next weekend.

Not trying to rush you into anything, but what's the status on making NBTLib compatible with MCPC?
I think it's a really cool plugin and I used it in Signshop to properly restore items to use in an infinite stock shop. (see here: https://github.com/wargamer/SignShop/blob/master/org/wargamer2010/signshop/blocks/NBTUtil.java)
Hope you don't mind :)

I can't really do anything about it.

How could this plugin be used to destroy anything at all?

Did he upload it somewhere?

If yes, why isn't it checked for malware?
If not, why would anyone install a plugin sent to them by a random stranger?

Someone named Digital copied your plugin claimed it was his own then used it to destroy other people's servers

I did some research on that topic and found out that MCPC actually does this kind of runtime-mapping already. I'm working on making NBTLib MCPC-compatible now.

If there were mappings (like the MCP .csv files) for the classes, fields and methods, I think I could write a plugin that modifies the bytecode of plugin classes before they are loaded and replace net.minecraft.server class names by the actual class names. Do you know if such mappings exist?

I'll test that out.

mcpc doesn't register a package called net.minecraft.server. I don't think there's as easy way to fix this. mcpc remaps the obfuscated class names.

Didn't test, but should work like this:

import java.util.HashMap;
import java.util.Map;
import org.bukkit.inventory.ItemStack;
import net.drgnome.nbtlib.NBT;
import net.drgnome.nbtlib.Tag;

ItemStack addTag(ItemStack stack)
{
    Map<String, Tag> data = NBT.itemStackToMap(stack);
    Tag<Map<String, Tag>> tag = (Tag<Map<String, Tag>>)data.get("tag");
    if(tag == null)
    {
        tag = Tag.newCompound(new HashMap<String,Tag>());
        data.put("tag", tag);
    }
    // The compound you want to add:
    Tag<Map<String,Tag>> myTag = Tag.newCompound(new HashMap<String,Tag>());
    // Fill myTag.get() here
    tag.get().put("my_NBT_key", myTag);
    return NBT.mapToItemStack(data);
}

What is the problem with MCPC?

How would I go about using this to get custom NBT from an item? When I say custom NBT i mean like a mod item with its own set of NBT tags.

I think so... the plugin itself doesn't do anything in-game, it just provides functions to other plugins (that's why it's called library).

Is it tekkit friendly? (for ex. IC2, Forestry)

This looks like a really awesome plugin to grab access to NBT data, thanks!
