Yeah, I've added macros `vec_len` and `vec_ptr` (or, enums, actually), which help somewhat. `arr[3]` should be flagged by the compiler it is known to the compiler that you're operating on an array. You can pass `arr` as `&arr`

Thank you! I implemented this pattern initially about a year ago, but decided to write about it now. Since you liked it, it wasn't for nothing. :)

You're right, I added some more clarity in the README. Interestingly, I think my approach will work fine on CHERI, since the pointer is never dereferenced, but I didn't test this. But yeah, there are some architectures where it wo

Good point! Added `vec_ptr[vec]` and `vec_len[vec]` helpers to mitigate this somewhat.

Thanks for mentioning it, I've heard about stb, but this time around I actually looked at the code. Their approach is very nice.

Making a strict subset of some existing language (Go) be a "better C" is quite an interesting idea compared to others (D, Zig, Hare, C3, D, ...), haven't seen it elsewhere. No new syntax. And Go seems to be a pretty good choi

Yes, but you can generate JSON with other tools easily. home.md describes how you can do it with Nix, but just as easily you can use Cue or something else. Edit: mentioned this in the README explicitly. Thanks!

Yeah, in general (a bit of a tangent), ideas from Plan 9 are really powerful. For example, the Acme text editor exposes it's API as a file system (it's represented via Unix sockets in plan9port, but FUSE is available as well there

Well, if you're generating JSON with Nix, you don't have to put everything inside of one file. It would be a better idea to split it up into multiple. You can also use builtins.readFile for reading config files which don't ha

YSH looks very nice here, thanks. I thought to mention YSH, but have no experience with it, so I hoped you would comment. (I guess we're duplicating threads at this point :D)

Sure. I have tried Bash namerefs. I found them to be kinda awkward, since you need to name them uniquely. So, you have to pretend that they are global variables, even though they are declared inside a function, which makes their usage verbo

Yeah, PowerShell and nushell are pretty cool, I hope they gain more adoption.

I like your approach. (Implicitly) using [1] instead of [false] as a default is less typing for sure (but maybe a bit more confusing?). Also, objects being switched on really have to be tables in my version anyway (since overriding __call f

Honestly, not much. I found it nice how it's possible to emulate switches in Lua with so little code, without the result looking too ugly. You may find this pattern useful. That's it. The catch is that, unlike with normal switches

Thanks, fixed.

In this case it doesn't matter much I think. I suppose the api existed for ages. But I prefer openbsd or man7 pages, sure.

As I understand, Bittorrent is not a persistent data structure. Git and IPFS are. Radicle is another interesting approach. They used IPFS but switched to a custom protocol, as I understand, for performance.

Here's how I understand it. One important (and beautiful) thing to understand about C is that declarations and use in C mirror each other. Consider the same type written in Go and C: array of ten pointers to functions from int to int.
