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

SharkPCB QMK firmware

sharkpcb

The SharkPCB is an open-source ortholinear 40% layout designed by Gondolindrim for the AcheronProject.

  • Keyboard Maintainer: Gondolindrim
  • Hardware Availability: you can get release Beta SharkPCBs using the JLCPCB manufacturer using the files at its documentation

How to flash

Enter bootloader

Release Alpha:

The DFU state in the bootloader can be accessed in 2 ways:

  • Bootmagic reset: hold down the key at (0,0) in the matrix (usually the top left key or Escape) and plug in the keyboard
  • Physical reset button: press the button on the back of the PCB
  • Keycode in layout: press the key mapped to QK_BOOT if it is available (ESC key at layer 1 in the default layout)

Release Beta:

The DFU state in the bootloader can be accessed in 3 ways:

  • Bootmagic reset: hold down the key at (0,0) in the matrix (usually the top left key or Escape) and plug in the keyboard
  • Physical reset button: press the button on the back of the PCB, for at least five seconds
  • Keycode in layout: press the key mapped to QK_BOOT if it is available (ESC key at layer 1 in the default layout)

Compile firmware

Release Alpha

After accessing the DFU state in your PCB, build the default layout using:

make acheron/shark/alpha:default

Release Beta

After accessing the DFU state in your PCB, build the default layout using:

make acheron/shark/beta:default

Then download the resulting binary *bin file using dfu-util or QMK Toolbox.
