Use a macro to compute the size of arrays at compile time (#18044)
* Add ARRAY_SIZE and CEILING utility macros

* Apply a coccinelle patch to use ARRAY_SIZE

* fix up some straggling items

* Fix 'make test:secure'

* Enhance ARRAY_SIZE macro to reject acting on pointers

The previous definition would not produce a diagnostic for
```
int *p;
size_t num_elem = ARRAY_SIZE(p)
```
but the new one will.

* explicitly get definition of ARRAY_SIZE

* Convert to ARRAY_SIZE when const is involved

The following spatch finds additional instances where the array is
const and the division is by the size of the type, not the size of
the first element:
```
@ rule5a using "empty.iso" @
type T;
const T[] E;
@@

- (sizeof(E)/sizeof(T))
+ ARRAY_SIZE(E)

@ rule6a using "empty.iso" @
type T;
const T[] E;
@@

- sizeof(E)/sizeof(T)
+ ARRAY_SIZE(E)
```

* New instances of ARRAY_SIZE added since initial spatch run

* Use `ARRAY_SIZE` in docs (found by grep)

* Manually use ARRAY_SIZE

hs_set is expected to be the same size as uint16_t, though it's made
of two 8-bit integers

* Just like char, sizeof(uint8_t) is guaranteed to be 1

This is at least true on any plausible system where qmk is actually used.

Per my understanding it's universally true, assuming that uint8_t exists:

* Run qmk-format on core C files touched in this branch

Included Keyboards

QMK runs on a diverse range of keyboards. Some of these keyboards are well maintained and see constant community contributions, while others are part of the repository for historical reasons.

Official QMK Keyboards

Ortholinear Keyboards - Jack Humbert

What makes OLKB keyboards shine is a combo of lean aesthetics, compact size, and killer tactile feel. These are available through olkb.com as well as through Massdrop from time to time, as easy to assemble kits.

  • Planck — A 40% DIY powerhouse of customizability and modification capability. It's a lean, mean, typing machine.
  • Preonic — Like the Planck, but bigger. 50%.
  • Atomic — Imagine the size of the Planck. Now imagine the size of the Preonic. Now imagine bigger. That is the Atomic. A 60% keyboard.

Clueboard - Zach White

Designed and built in Felton, CA, Clueboards keyboard emphasize quality and locally sourced components, available on clueboard.co

  • Clueboard — The 66% custom keyboard.
  • Cluecard — A small board to help you hack on QMK.
  • Cluepad — A mechanical numpad with QMK superpowers.

ErgoDox EZ and Planck EZ - ZSA Technology Labs

ZSA Technology Labs maintains its own fork of QMK which feeds its configurator, for stability and legal purposes. The ZSA boards are:

  • ErgoDox EZ — A powerful split mechanical keyboard.
  • Planck EZ — A 40% DIY powerhouse of customizability and modification capability. It's a lean, mean, typing machine, which ships fully assembled with a two-year warranty.

Community-supported QMK Keyboards

These keyboards are part of the QMK repository, but their manufacturers are not official maintainers of the repository.

Since there are too many to list here and keep updated, please see the folder listing instead.
