# MenuLock
implements CMD+L for windows enthusiasts
To be more precise, it puts display to sleep.

To lock your computer, you need to have `System Preferences > Security & Privacy > Require the password Immediately after sleep saver begins`, and a password set.

(Hi, Cédric!)

# Why ? 
- Because Keychain Access' menubar introduce the question: "Why lock keychain?"
- Because ctrl+shift+power/eject can become halt or reboot if user is not careful
- Because Hot Corners are not loved by everyone (and they only start screensaver)

# Some details

## Building the App

### Workspace Setup
This app uses [Cocoapods](https://cocoapods.org). Please first install it (usually with `sudo gem install cocoapods`).
Then follow this:

- `git clone https://github.com/ftiff/MenuLock.git`
- `cd MenuLock`
- `pod install`
- `open MenuLock.xcworkspace/`

Then go to `Product > Scheme > Edit Scheme…` and make sure `Run > Executable` is set to "MenuLock.app".

### Build
- Modify APP_VERSION in Build Settings (see https://ftiff.wordpress.com/2016/04/01/xcode-automatically-sign-and-build-package/)
- In Terminal.app, navigate to the MenuLock directory
- `xcodebuild -workspace MenuLock.xcworkspace -scheme MenuLock install`

### install
- `sudo installer -target / -pkg /tmp/MenuLock-1.1.pkg`
- `sudo launchctl load /Library/LaunchAgents/io.fti.MenuLock.plist`

## Key Modifiers

`let keyMask: NSEventModifierFlags = [ .AlternateKeyMask, .ShiftKeyMask]`

event modifier flag | Description
--------------------|------------
AlphaShiftKeyMask | Caps Lock 
ShiftKeyMask | Shift
ControlKeyMask | Control
AlternateKeyMask | Alt
CommandKeyMask | Command
NumericPadKeyMask | Set if any key in the numeric keypad is pressed (and arrows)
HelpKeyMask  | Help Key (does this still exists?)
FunctionKeyMask | The function keys include the F keys at the top of most keyboards (F1, F2, and so on) and the navigation keys in the center of most keyboards (Help, Forward Delete, Home, End, Page Up, Page Down, and the arrow keys).

## Key Code

`let keyCode = UInt(0x25)`

These are defined in `/System/Library/Frameworks/Carbon.framework/Versions/A/Frameworks/HIToolbox.framework/Versions/A/Headers/Events.h`. Be careful these work for US Keyboards. I'd love to learn a better way to do this.
