Replicating the full macOS ABC Extended Keyboard with XKB

In the previous post I created a fix for some of the missing dead keys in the us(mac) layout I use on NixOS

Today I thought, why not simply replicate the entire layout?

A quick search (with ChatGPT) gave me this great resource with an entire spec for the ABC Extended layout.

It was only a matter of giving ChatGPT an example and telling it to convert everything to xkb. Here’s the result, althought I haven’t actually tested every single case:

default partial default alphanumeric_keys
xkb_symbols "extended" {
  name[Group1]= "ABC Extended (macOS)";

  key.type[group1]="FOUR_LEVEL";

  // Numbers row
  key <TLDE> { [ grave, asciitilde, dead_grave, dead_horn ] };
