Project mention: How to manage files in an OOP project? | reddit.com/r/learnprogramming | 2021-11-18
I agree with this, what you may do is pick a large and successful open source c++ project and mimick their structure. Here's the link to Google's V8 javascript engine (core of nodejs/Google chrome js engine) and my logic going forward would be "if it's good enough for a large company and a massive open source community it's probably good enough for me too" https://github.com/v8/v8

sol2
Sol3 (sol2 v3.0) - a C++ <-> Lua API wrapper with advanced features and top notch performance - is here, and it's great! Documentation:
Project mention: Design Issues for Foreign Function Interfaces (2004) | news.ycombinator.com | 2021-11-30Very interesting article!
Unfortunately, it doesn't mention Lua, which in my opinion has one of the most elegant C APIs that I have seen. It is entirely stack based, which means you only need to work with primitive types, such as numbers, C strings and user provided opaque pointers. As a consequence, you never have to care about memory management because Lua doesn't even let you access the actual Lua objects.
You want to create a table (= Lua's dictionary/array hybrid) and set a field "foo" to 5? lua_newtable() creates a new table and pushes it onto the stack. Then you push "foo" with lua_pushstring() and 5 with lua_pushnumber(). Finally you call lua_settable(), which pops the key and value from the stack, checks if the top of the stack contains a table, and if yes, sets the given field to the given value. The actual table structure is never exposed!
This kind of stack manipulation might seem unusual and a bit unweildy, but what you get is safety. If you mess up the stack or perform illegal operations, Lua will call an error handler, but the VM should never crash. The stack API can be seen as the fundamental layer upon which people can create nice abstractions for their host language of choice. Examples are "sol2" for C++ (https://github.com/ThePhD/sol2) or "lupa" for Python (https://github.com/scoder/lupa)
The public API is contained in "lua.h": https://github.com/lua/lua/blob/master/lua.h. "lauxlib.h" offers some useful helper functions: https://github.com/lua/lua/blob/master/lauxlib.h
For comparison, this is Python's "Limited" C API: https://docs.python.org/3/c-api/stable.html#stable
If you want to learn more about Lua's C API, have a look at section 4 in https://www.lua.org/manual/5.4/manual.html

Project mention: Requesting r/Luau, it seems to be unused and private and I would like to open it for use for people with the recent open sourcing of Roblox's Luau programming language | reddit.com/r/redditrequest | 2021-11-29
Nope, they use their own heavily modified version of Lua that has recently split off from Roblox: https://luau-lang.org

Project mention: [AskJS] C++ -> compile to both wasm for web and binary add-on for node.js? | reddit.com/r/javascript | 2021-01-29
nbind aimed to do that, but it's difficult to maintain, and it didn't take off.

open-builder
Open "Minecraft-like" game with multiplayer support and Lua scripting support for the both client and server
Project mention: Some early gameplay from my voxel game: Wanderers | reddit.com/r/VoxelGameDev | 2020-12-28For example, in this Notch article, he discussed using trilinear interpolation to speed up noise evaluation as well as to smooth out rough parts. But I tested, and both of his problems actually came mostly from using too many noise octaves. Minecraft used 16 octaves for each noise channel, and 8 octaves for the blending noise, when just 5-6 and 2-3 would be enough. The rest of the speed problems could be solved by implementing something to skip noise evaluations when they wouldn't matter, at least above/below max/min biome height if not dynamic octave skipping. See this screenshot difference.
