For a while now I have been dabbling with zig and as a small test writing a NES-emulator (everyone should have written an 8-bit emulator in their life right?). While doing this I stumbled upon a kind of neat trick that you can do in zig that I thought was worth sharing… with kind of a “anti-climactic” end!

Some background

While writing some debug-tools I decided that I wanted to switch between ppu-palettes when displaying some data. At this time the available palettes were all described with an enum.

Hashing strings in c++ at compile time has been possible since c++11 but is it worth doing? Me and a few colleagues was discussed this over a few beers and it reminded me that I have already written about it here (8 years ago… ARGH I’m getting old!).

But a lot of time has passed since I wrote that… and I didn’t make any measurements in that article! shame! SHAME I SAY!

Note: before we begin, finding a name for this post was really hard!

In this post I’m going to touch on a c++-technique to handle callbacks that I have not seen written about before and that many of my colleagues hadn’t seen before either. Probably it’s not something new and some of you will probably just say “yeah yeah, nothing new under the sun” but it’s probably worth a few words!
