Where is inventory parser

[isXander]

Hey! I was looking to make a discord bot similar to this so I was thinking I could translate your nbt parser to python but can't seem to find the code that does it. Could you link the file and line number?

src/lib.js#L227

Here's a version already in python if you still need it It also doesn't use any nonstandard libraries

`from base64 import b64decode as one from gzip import decompress as two from io import BytesIO as three from struct import unpack def decode_inventory_data(raw, backpack=False): if backpack: raw = three(two(raw))
else: raw = three(two(one(raw))) # Unzip raw string from the api

def read(type, length):
    if type in 'chil':
        return int.from_bytes(raw.read(length), byteorder='big')
    if type == 's':
        return raw.read(length).decode('utf-8')
    return unpack(f'>{type}', raw.read(length))[0]

def parse_list():
    subtype = read('c', 1)
    payload = []
    for _ in range(read('i', 4)):
        parse_next_tag(payload, subtype)
    return payload

def parse_compound():
    payload = {}
    while parse_next_tag(payload) != 0:  # Parse tags until we find an endcap (type == 0)
        pass  # Nothing needs to happen here
    return payload

What variable does raw have to be? String doesnt work

[notnotmelon]

It must be a binary string (created with b"")
