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

THIS IS THE DEVELOP BRANCH

Warning- This is the develop branch of QMK Firmware. You may encounter broken code here. Please see Breaking Changes for more information.

Quantum Mechanical Keyboard Firmware

Current Version Discord Docs Status GitHub contributors GitHub forks

This is a keyboard firmware based on the tmk_keyboard firmware with some useful features for Atmel AVR and ARM controllers, and more specifically, the OLKB product line, the ErgoDox EZ keyboard, and the Clueboard product line.

Documentation

The docs are powered by Docsify and hosted on GitHub. They are also viewable offline; see Previewing the Documentation for more details.

You can request changes by making a fork and opening a pull request, or by clicking the "Edit this page" link at the bottom of any page.

Supported Keyboards

The project also includes community support for lots of other keyboards.

Maintainers

QMK is developed and maintained by Jack Humbert of OLKB with contributions from the community, and of course, Hasu. The OLKB product firmwares are maintained by Jack Humbert, the Ergodox EZ by ZSA Technology Labs, the Clueboard by Zach White, and the Atreus by Phil Hagelberg.

Official Website

qmk.fm is the official website of QMK, where you can find links to this page, the documentation, and the keyboards supported by QMK.
