tab-bar-notch

Adjust tab-bar height for MacBook Pro notch.

When using the non-native fullscreen mode of Emacs on modern MacBook Pro machines, it ends up rendering buffer content behind the camera notch. This package attempts to solve this by way of resizing the tab-bar to fill the vertical space taken up by the camera notch.

Obviously tab-bar-mode must be enabled with the tab-bar visible at the top of the frame for this package to be able to function.

Non-Native Fullscreen?

The default native fullscreen implementation on macOS can be rather annoying, as it moves applications over to their own separate desktop Space. This prevents you from layering windows from other applications on top it, among other things.

Emacs supports both native and non-native fullscreen modes. In the non-native mode, Emacs just acts like any other window, but stretches itself to cover the whole screen, and hides the menu bar and dock. Non-native fullscreen is enabled with:

(setq ns-use-native-fullscreen nil)

In the non-native fullscreen mode, Emacs is not aware of the physical camera notch however, so it does not know to avoid rendering things behind it.

Installation

tab-bar-notch is available via MELPA.

use-package

(use-package tab-bar-notch)

Manual

Place tab-bar-notch.el somewhere in your load-path and require it. For example ~/.emacs.d/vendor:

(add-to-list 'load-path "~/.emacs.d/vendor")
(require 'tab-bar-notch)

Usage

You must be using tab-bar-mode, with the tab-bar visible at the top of the frame above all buffers.

Then simply add tab-bar-notch-spacer to the tab-bar-format variable, for example:

(setq tab-bar-format '(tab-bar-format-history
                       tab-bar-format-tabs
                       tab-bar-separator
                       tab-bar-format-add-tab
                       tab-bar-notch-spacer))

To disable the package, simply remove tab-bar-notch-spacer, and it will unregister itself from window resizing hooks.
