Install

npm i -g @kszongic/bitmask-cli

Usage

bitmask and 0xFF 0x0F        # 15 (0b00001111)
bitmask or 0b1010 0b0101     # 15 (0b00001111)
bitmask xor 12 7             # 11 (0b00001011)
bitmask not 0                # -1 (0b11111111111111111111111111111111)
bitmask lshift 1 8           # 256 (0b100000000)
bitmask rshift 256 4         # 16 (0b10000)
bitmask set 0 3              # 8 (0b00001000)
bitmask clear 0xFF 4         # 239 (0b11101111)
bitmask toggle 0b1010 1      # 8 (0b00001000)
bitmask check 0xFF 7         # 1 (bit 7 is set)
bitmask bits 255             # 11111111
bitmask popcount 0xFF        # 8
bitmask mask 8               # 255 (0b11111111)

Numbers can be decimal, hex (0x), octal (0o), or binary (0b).
