Bitwiser is a collection of methods and properties that makes you work with
nibbles a piece of cake
The project is in early stages of development feel free to make pull requests for more funcionalities
- No more bit masking. Access single bit values
- Coverting from bytes array to
Dataand back has never been easier
Datainto hex string
- Set, reset, query, toggle each bit
- Chaining methods
- Extensive code coverage
- Multiplatform: iOS, macOS, tvOS, watchOS, Linux, Windows
Use Swift package manager.
Add the following dependency to your Package.swift file:
.package(url: "https://github.com/DrAma999/BitWiser.git", from: "0.0.1")
Or simply add the URL from XCode menu Swift packages.
HOW TO USE IT
Byte is simply a
UInt8 that has been extended to access single bit values.
Bit is an enumeration that can assume two values
var value = Byte(0b1010_1010) let bits = value.bits print(bits) // [0, 1, 0, 1, 0, 1, 0, 1]
Note: Bits representation is shown as an array of
Bit where the array index 0 represents the least significant bit
After creating a
Byte you can read in its position in different ways:
let bit = value
// Query the value let bit = value.bit(0) // Ask if bit is set (equal to one) let isSet = value.isBitSet(0)
let bit = value.b0
After creating a mutable
Byte you can write in its position in different ways:
value = 1
// Set the specified bit to 1 value.setBit(0) // Reset the specified bit to 0 value.resetBit(0) // Toggle the specified bit. If the bit in position zero is one it becomes zero and viceversa value.resetBit(0) // Change the value of the specified bit to one value.changeBit(0, to: .one ) // Chaining modifiers that return a new value without mutating let newValue = value .settingBit(0) .resettingBit(3) .togglingBit(4)
value.b0 = .zero
Pretty sure that if you worked in IOT you had an embedded engineer that put some infomration inside a nibble.
With bit wiser you can extract nibbles from a byte:
let value: Byte = 0b01011111 let (msb, lsb) = value.nibbles
There are also a lot of methods and facilities to work with bit bites and nibbles.
Since I’m working on this project in my spare time any help is appreciated.
Feel free to make a pull request.
