# go-touchbar [](https://pkg.go.dev/github.com/LouisBrunner/go-touchbar) Go library to integrate the MacBook Touch Bar ## Installation ```bash go get github.com/LouisBrunner/go-touchbar ``` ## Usage ```go // Setup your window code (including NSApplication/NSWindow on macOS) tb := touchbar.New(touchbar.Options{}) err := tb.Install(Configuration: touchbar.Configuration{ // Add your configuration here }) if err != nil { // handle } // run your application // when you want to update the touchbar (even from another routine), call do err = tb.Update(Configuration: touchbar.Configuration{ // Add your updated configuration here }) if err != nil { // handle } err = tb.Uninstall() if err != nil { // handle } ``` ### Configuration https://user-images.githubusercontent.com/7120871/197391736-450bef36-4dd6-4c79-8ae7-3bd68a932eec.mp4 See [example application](./examples/tester/main.go) for a real-life example. Note: most of the widgets are direct translations of the one in Apple's documentation and have similar options. Please refer to [the official documentation](https://developer.apple.com/documentation/appkit/touch_bar/creating_and_customizing_the_touch_bar?language=objc) for more details. You configure this library by specifying a list of items from the following options: - `Button`: a button that can be clicked (has an event handler) - **NOT IMPLEMENTED** `Candidates`: a list of text options, allows to give custom recommendations for the current text field - **NOT IMPLEMENTED** `ColorPicker`: used to choose a color (has an event handler) - **NOT IMPLEMENTED** `Custom`: can render anything you want, feedback any touch with a X position (has an event handler) - **NOT IMPLEMENTED** `Group`: used to group other items - `Label`: allows to display text and images - **NOT IMPLEMENTED** `Picker`: used to pick one or more options from a list of choices, equivalent to radio/checkbox buttons (has an event handler) - `Popover`: a button which shows more options when clicked, equivalent to a modal or collapse widget - **NOT IMPLEMENTED** `Scrubber`: allows to select items from a list, which supports scrolling (has an event handler) - **NOT IMPLEMENTED** `SegmentedControl`: shows multiple buttons grouped together, similar to `Picker` (has an event handler) - **NOT IMPLEMENTED** `Sharer`: allows to share using the standard macOS sharing system - `Slider`: a slider used to pick value in a range (has an event handler) - **NOT IMPLEMENTED** `Stepper`: a control to pick a value in a range through increments (has an event handler) But also from this list of standard Apple widgets which have no customizable options: - `OtherItemsProxy`: where to display other Touch Bar closer to the first responder - `SpaceSmall`: a small space - `SpaceLarge`: a bigger space - `SpaceFlexible`: a space that grows as much as possible <!-- - `CharacterPicker`: opens the macOS character picker (e.g. to pick an emoji) - `CandidateList`: shows the standard macOS predictive text widget - `TextFormat`: a group of text formatting options - `TextAlignment`: allows to pick text alignement - `TextColorPicker`: allows to pick text color - `TextList`: allows to pick text listing options - `TextStyle`: allows to pick text style --> ## Further work Check TODO/FIXME as well - (!!!) Finish implementing widgets - Allow user customization (`customizationLabel`, `templateItems`, etc) - Layout constraints (e.g. sizing) - More options for widgets: - Color-picker - Custom - Popover - Support standard/UI colors - Support custom images - Better validation in Go (validator on the structs?) - A few random crashes: `signal arrived during cgo execution` and `[touchBar itemIdentifiers] was mutated while items array was being built` (in `[WindowController setupTouchBar]`) ## Acknowledgements This library's API was influenced by [Electron's](https://www.electronjs.org/docs/latest/api/touch-bar). The [demo application](./examples/tester/demo.go) is a reimplementation of [`electron-touch-bar`](https://github.com/pahund/electron-touch-bar). The [catalog](./examples/tester/catalog.go) was influenced by [Apple's](https://developer.apple.com/documentation/appkit/touch_bar/creating_and_customizing_the_touch_bar?language=objc), which also helped with the Objective-C part of the implementation.
