This does not support the Minecraft education edition level.dat files. about nbtlib HOT 3 CLOSED

@DudleyFox I just published version 1.2.0, which now supports little-endian nbt data. I added a byteorder argument to most functions and methods. It defaults to 'big' for backward compatibility but you can set it to 'little' to use the little-endian format.

parsed_compound = Compound.parse(some_file, byteorder='little')

I also added an example in the examples folder that showcases how you could use nbtlib to read and edit level.dat files from Bedrock-based Minecraft editions. The level_dat_bedrock.py example defines a BedrockLevelFile class that takes care of parsing the header and the content of the file using the little-endian format.

# This is how you would edit a level.dat file

with BedrockLevelFile.load('level.dat') as level_data:
    level_data['LevelName'] = 'Something'

For the sake of convenience, I attached a schema that matches the structure of the level.dat file to the BedrockLevelFile class, but that's completely optional.

nbtlib currently uses big-endian byte ordering, which is the format used by the original version of Minecraft. I know that versions of Minecraft based on the pocket edition use little-endian ordering, so making it possible to choose the endianness when reading and writing nbt data is on my todo list.

However, nbtlib is not a library for working with Minecraft files specifically. It's an implementation of the official nbt specification. Nbt data is used in a lot of different ways, and it's often integrated within other file formats. This library is supposed to let you read sections of files that contain spec-conforming nbt data. It won't work out of the box on files that do not contain raw nbt data, such as the Minecraft Education level.dat file since it has a header that you'll need to parse yourself before getting to the section that contains actual nbt data.

That is very nice. Thank you!
