I wrote a zig macro.

import 'ffi'


macro zig = (code)->
	import 'md5'
	dir, fn = 'embed/', md5.sumhexa(code) -- without ext (.zig/.h/.so)
	with io.open(dir..fn..'.zig', 'w')
		\write(code)
		\close()
	cmd = code\match('^//#(.-)\n') or 'zig build-lib -dynamic -O ReleaseSmall' -- -fstrip -fsingle-threaded'
	-- os.execute(command or "pushd &>/dev/null #{dir} && #{cmd} #{fn}.zig -femit-h -target x86_64-windows-gnu && popd &>/dev/null")
	os.execute(command or "pushd &>/dev/null #{dir} && #{cmd} #{fn}.zig -femit-h && popd &>/dev/null")
	_h = io.open(dir..fn..'.h')\read('*a')\gsub('#include "zig.h"\n', '')\gsub('zig_extern ', '')--\gsub('\n','')
	"rawget({ffi.cdef\'#{_h}\', ffi.load\'#{dir}lib#{fn}.so\'}, 2)"


fib = $zig[[
export fn fib(n: i32) i32 {
    if (n == 0 or n == 1) return n;
    return fib(n - 1) + fib(n - 2);
}
]]


print fib.fib(10)
print 250 + 10
print 250 |>$zig[[export fn u8addwrap(a: u8, b:u8) u8 {return a +% b;}]].u8addwrap 10
print 250 |>$zig[[export fn u8addsatu(a: u8, b:u8) u8 {return a +| b;}]].u8addsatu 10

brighten = $zig[[

    var idx: usize = 0;
    const add_vec = @Vector(4, u8){ 10, 10, 10, 0 };
    while (idx < len) : (idx += 4) {
        const image_vec = @Vector(4, u8){ image[idx + 0], image[idx + 1], image[idx + 2], image[idx + 3] };

    }
}
]]

image = string.char unpack [math.random(0, 255) for _ = 1, 1200]
print string.byte image, 1, 10
for _=1,9
	brighten.brightenSIMD(ffi.cast('uint8_t *', image), #image)
	print string.byte image, 1, 10


qoi = $zig[[
//# cp -f ../qoi.h qoi.h && zig build-lib -dynamic -O ReleaseSmall -I. -I/usr/include

	var desc = qoi.qoi_desc{.width = 0, .height = 0, .channels = 0, .colorspace = 0};
	var result = qoi.qoi_read(filename, &desc, 4);
	pwidth.* = desc.width;
	pheight.* = desc.height;
	return result;

}
]]

pwidth, pheight = ffi.new('uint32_t[1]'), ffi.new('uint32_t[1]')
pixels = qoi.read('dice.qoi', pwidth, pheight)
-- gr.newImage(love.image.newImageData(pwidth[0], pheight[0], 'rgba8', ffi.string(pixels, pwidth[0] * pheight[0] * 4)))
print pwidth[0], pheight[0]

The issue only provides an inline YueScript/Lua macro and embedded Zig examples; no repository file, test, or entry point is named. Read the macro and its Zig build commands first, then clarify the intended project change and acceptance criteria before starting.
