scratch VS chars

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.

All of mine are CLI...

https://github.com/jftuga/less-Windows - [not really mine, but I just help maintain the port] - GNU less compiled for Windows 10 & 11. Stand-alone version with no dependencies.

https://github.com/jftuga/gofwd - A cross-platform TCP port forwarder with Duo 2FA and Geo-IP integration

https://github.com/jftuga/spotprice - Quickly get AWS spot instance pricing - a bit easier to use than the aws cli; is also faster and has more features

https://github.com/jftuga/tcpscan - A standalone, fast, simple, multi-threaded cross-platform IPv4 TCP port scanner

https://github.com/jftuga/ipinfo - Return IP address info including geographic location and distance when given IP address, email address, host name or URL

https://github.com/jftuga/photo_id_resizer - Resize photo ID images using face recognition technology

https://github.com/jftuga/chars - Determine the end-of-line format, tabs, bom, and nul characters
