flecs

48 5,475 9.7 C

A fast entity component system (ECS) for C & C++

Project mention: ECS, Finally | news.ycombinator.com | 2023-12-30

I've also been enjoying building My First Game™ in Bevy using ECS. The community around Bevy really shines, but Flecs (https://github.com/SanderMertens/flecs) is arguably a more mature, open-source ECS implementation. You don't get to write in Rust, though, which makes it less cool in my book :)
I'm not very proud of the code I've written because I've found writing a game to be much more confusing than building websites + backends, but, as the author notes, it certainly feels more elegant than OOP or globals given the context.
I'm building for WASM and Bevy's parallelism isn't supported in that context (yet? https://github.com/bevyengine/bevy/issues/4078), so the performance wins are just so-so. Sharing a thread with UI rendering suuucks.

metalang99

42 763 3.7 C

Full-blown preprocessor metaprogramming

Project mention: How to convert an enum to string in C++ | news.ycombinator.com | 2023-09-30

There are also other approaches. Macro variants making use of `__VA_ARGS__` would be probably the best trade-off. If you want a slightly more ergonomic syntax, something like Metalang99 [1] will help (and the author even wrote a post about this exact subject [2]). Codegen is another option which may work better than other options depending on the situation and exact implementation strategy. And there is always the Reflection TS [3], which may or may not be incorporated to C++26...

LVGLBuilder

1 381 1.8 C

GUI Builder for littlevgl.
fdpp

4 182 9.2 C

FreeDOS plus-plus, 64bit DOS

Project mention: Programming with DOS Debugger (2003) | news.ycombinator.com | 2024-04-07

Some implementations are 64 bits, such as this one: https://github.com/dosemu2/fdpp
I wish there were an ARM-compatible version of DOS, if possible stateless. It would often be more suitable for an ARM board than a full-fledged Linux, given its almost non-existent attack surface, low resource consumption, and simplicity. Heck, I'd even like to see stateless DOS based microservices on nano-VMs.
