Opening servers.dat.

[taitep]

I want to try adding some servers to the list using python, and seems this library would work. Testing it out does not go so well tho. I opened the .minecraft folder in a terminal, and in the python shell wrote the following:

>>> from nbt import nbt
>>> nbtfile = nbt.NBTFile('./servers.dat')

I get this error:
gzip.BadGzipFile: Not a gzipped file (b'\n\x00')
How do i fix this? Do i need to GZip it first?

Same for

from nbt import nbt
og_servers_dat = "src_servers.dat"

with open(og_servers_dat, "rb") as input_file:
    nbtfile = nbt.NBTFile(fileobj=input_file)

gzip.BadGzipFile: Not a gzipped file (b'\n\x00')

The approach that works for me is using the following

from nbt import nbt
with open('./servers.dat', 'rb') as reader:
    nbtfile = nbt.NBTFile(buffer=reader)
    for server in nbtfile["servers"]:
        print(server)

If you don't open the file as binary, the package will report error a bytes-like object is required, not 'str', which alternative there is do buffer=reader.buffer to get the underlying buffer of bytes from the TextIOWrapper, but better to open it binary/bytes in the first place.
