SpiceKey

Global Shortcuts for macOS written in Swift.

Requirements

• Development with Xcode 15.0.1+
• Written in Swift 5.9
• swift-tools-version: 5.8
• Compatible with macOS 11.0+

Demo

Demo App is in this Project.

Usage

• Register a shortcut

Set ⌘ + A shortcut.

let key = Key.a
let modifierFlags = ModifierFlags.cmd
let keyCombo = KeyCombination(key, modifierFlags)
let spiceKey = SpiceKey(keyCombo, keyDownHandler: {
    // process (key down)
}, keyUpHandler: {
    // process (key up)
})
spiceKey.register()

Set press both side of ⌘ shortcut.

let flag = ModifierFlag.command
let spiceKey = SpiceKey(flag, bothModifierKeysPressHandler: {
    // process (press)
}, releaseKeyHandler: {
    // process (release)
})
spiceKey.register()

Set long press ⌘ shortcut.

// run after 0.6 sec
let flags = ModifierFlags.cmd
let spiceKey = SpiceKey(flags, 0.6, modifierKeysLongPressHandler: {
    // process (press)
}, releaseKeyHandler: {
    // process (release)
})
spiceKey.register()

• Create a Key and a ModifierFlags from NSEvent.

func example(event: NSEvent) {
    let key = Key(keyCode: event.keyCode)
    let flags = event.modifierFlags.intersection(.deviceIndependentFlagsMask)
    let modifierFlags = ModifierFlags(flags: flags)
}

• Get a description of the shortcut

let description = modifierFlags.string + key.string
// or
let description = keyCombination.string

• Unregister a shortcut

spiceKey.unregister()

• Save shortcut

SpiceKeyData supports NSCoding & Codable.

let key = Key.a
let flags = ModifierFlags.optCmd
let spiceKey = SpiceKey(...)

let spiceKeyData = SpiceKeyData(
    _ primaryKey: String,
    _ keyCode: CGKeyCode,  // key.keyCode
    _ control: Bool,       // flags.containsControl
    _ option: Bool,        // flags.containsOption
    _ shift: Bool,         // flags.containsShift
    _ command: Bool,       // flags.containsCommand
    _ spiceKey: SpiceKey   // spiceKey
)
// OR
let spiceKeyData = SpiceKeyData(
    _ primaryKey: String,
    _ key: Key,
    _ modifierFlags: ModifierFlags,
    _ spiceKey: SpiceKey
)
// OR
let spiceKeyData = SpiceKeyData(
    _ primaryKey: String,
    _ keyCombination: KeyCombination,
    _ spiceKey: SpiceKey
)

// NSCoding
let data = try! NSKeyedArchiver.archivedData(withRootObject: spiceKeyData,
                                             requiringSecureCoding: false)
UserDefaults.standard.set(data, forKey: "spiceKeyData")

// Codable
let data = try! JSONEncoder().encode(spiceKeyData)
UserDefaults.standard.set(data, forKey: "spiceKeyData")

• Load shortcut

// NSCoding
let data = UserDefaults.standard.data(forKey: "spiceKeyData")!
let spiceKeyData = try! NSKeyedUnarchiver
    .unarchiveTopLevelObjectWithData(data) as! SpiceKeyData

// Codable
let data = UserDefaults.standard.data(forKey: "spiceKeyData")!
let spiceKeyData = try! JSONDecoder().decode(SpiceKeyData.self, from: data)

SpiceKeyField & SKTextField

A special text field that can be used to register SpiceKey.

• SpiceKeyField is for AppKit only.
• SKTextField is a SpiceKeyField made available from SwiftUI.

Please see the Demo App for detailed instructions.
