Module for reading/writing chunk files.
pip install pychunker
example.py:
import pychunker
with pychunker.open("chunkfile.bin", "w") as cf:
# The chunk can be used via `with'.
with cf.chunk("DDAT") as ddat:
ddat.write(b'1234567890')
# Or by contacting the key (name of the chunk).
cf["SDAT"].write(b'Hello World!')
# !!! Attention !!!
# Both types of treatment use the same methods,
# namely that if you open a chunk file in read-only mode,
# and if the chunk is not in the chunk file,
# he will try to create a chunk,
# but he will not be able to do this and will give a `IONotWritableError`.
with pychunker.open("chunkfile.bin") as cf:
print(cf.chunks)Output:
[Chunk(name='DDAT', mode='r', size=10), Chunk(name='SDAT', mode='r', size=12)]
