Input/output utilities of a bit-basis file
Project description
bitio
Utilities to read or write files by bit or bits
How to use
from bitio import bit_open
f = bit_open(file_name, "r")
x = f.read() # return 1 or 0
x = f.read_bits(count) # return int
f = bit_open(file_name, "w")
f.write(bit) # write 1 if bit else 0
f.write_bits(bits, count) # write 'count bits'
f.close()
These are the same
f.write_bits(bits, count)
for i in range(count-1, -1, -1):
if bits & (1 << i):
f.write(1)
else:
f.write(0)
Another interface
l = []
wrapper = ByteWrapper(l.append)
f = bit_wrap(wrapper, "w")
f.write_bits(0b110000101, 10)
print(l) # [b"a"]
f.close()
print(l) # [b"a", b"@"]
