colorguard 0.4

Better bit manipulation that allows indexing, and automatic bit flags.

Color Guard provides simple bit manipulation and bit flags in Python. Everything is built on the int type so no number functionality is lost, while making it possible to index and slice binary numbers like strings.

---

Basic usage:

>>> num = Bits(20)
>>> num
Bits(0b10100)
>>> num * 3
Bits(0b111100)
>>> num[:4]
Bits(0b1010)
>>> num.bit_length()
5
>>> num.join(0b101)
Bits(0b10100101)

Color Guard also supports conversion to and from other Python data types.

>>> Bits.from_binary("111101001101")
Bits(0b111101001101)
>>> Bits.from_hex("abc123")
Bits(0b101010111100000100100011)
>>> Bits.from_bytes(b"abc")
Bits(0b11000010110001001100011)

>>> bytes(Bits(367))
b'\x01o'
>>> int(Bits(0b1011010))
90
>>> list(Bits(367))
[1, 0, 1, 1, 0, 1, 1, 1, 1]
