scratch VS PL3D-KC

pbmview, an image viewer (windows subsystem).

For comparison (for those following along): https://github.com/skeeto/scratch/blob/master/parsers/qoi.c https://github.com/skeeto/scratch/blob/master/parsers/ini.c

Another option I learned a couple years ago is embedding a UTF-8 manifest ([details])[https://github.com/skeeto/scratch/tree/master/libwinsane]. Also put the console in UTF-8 mode (SetConsoleOutputCP(CP_UTF8)), and you're done. Works on Windows 10 and later. This covers everything: argv is UTF-8 and fopen accepts UTF-8 paths. (This is exactly how CRTs should have worked all along.)

I was thinking more about this and I realized it's quite easy to do it in arbitrary precision, so here's my take: https://github.com/skeeto/scratch/blob/master/misc/bswap.c

As was linked from my QOI article, here's my full decoder with comments: qoi.c. Each pixel decodes to a 32-bit integer, ABGR. That corresponds to SDL's SDL_PIXELFORMAT_ABGR8888. SDL_UpdateTexture copies that data into the texture's internal storage, and font is no longer needed. (In a real program I'd allocate it in a scratch arena, reset after initialization.)

A recent, interesting experience with function+context allocation: For more than a decade, Windows accidentally exposed part of zlib in a public DLL, and (overly-)clever applications can exploit this as a "system zlib." Though it doesn't export the "end" functions, so cleanup seems impossible. However, custom allocation works, so doesn't matter. I plugged it into an arena.

PiSHi LE (PL) is a subset of the 3D graphics library used in King's Crook. FW LE is a subset of the windowing library used in King's Crook. Just like King's Crook, this code follows the same restrictions: 1. Everything must be done in software, no explicit usage of hardware acceleration. 2. No floating point types or literals, everything must be integer only. 3. No 3rd party libraries, only C standard library and OS libraries for window, input, etc. 4. No languages used besides C. 5. No compiler specific features and no SIMD. 6. Single threaded. https://github.com/LMP88959/PL3D-KC If you are using macOS, go to fw.h and change FW_X11_IS_MACOS to 1. Compiling for macOS/Linux: cd PL3D-KC gcc -lX11 -lXext -O3 *.c fw/*.c -o pl ./pl Compiling for Win32 is a bit more involved, I've only used Visual Studio to develop for Windows but this program doesn't use anything other than the Win32 library and winmm.lib (don't forget to link against winmm.lib!). Of course, you're not limited to using Visual Studio, feel free to use any build system you're comfortable with under Windows. Don't forget to compile with max optimization!
