NBT library for C++17

You can read and save files in NBT format with this library. It supports different formats: NBT Java Edition, NBT Bedrock Edition (both network and file formats) and Mojangson.

Usage

#include <nbt.hpp>
#include <fstream>

using namespace nbt;

int main() {
    std::ifstream input("java.nbt");
    tags::compound_tag root;
    input >> contexts::java >> root;
    std::ofstream output("mojangson.txt");
    output << contexts::mojangson << root;
}

By default all lists have their own specialization for each tag. If you want to get something simple like std::vector<nbt::tags::tag> as list values you can use nbt::tags::tag_compound::make_heavy and nbt::tags::list_tag::as_tags. After that all lists in NBT subtree would be nbt::tags::tag_list_tag objects.

NBTC

There are also a simple converter between NBT formats: nbtc.

./nbtc FROM TO

Parameters:

• FROM read stdin as FROM NBT format
• TO write NBT tag to stdout as TO format

NBT formats:

• java Minecraft Java Edition NBT
• bedrock or bedrock-disk Minecraft Bedrock Edition storage NBT format
• bedrock-net Minecraft Bedrock Edition network NBT format
• mojangson text NBT representation
• kbt HandTruth NBT extension
