Interesting; while I knew about `preserve_all` and `preserve_most` attributes, I didn't have an inkling that they've added `preserve_none`. But that's much cleaner that the traditi…

.* does NOT match newlines, so always will stop a match at the end of a line.

For me, I’ve got use cases where it’s valuable to keep event data interleaved because it will also get used in flight. It works well enough I also use it for things where it’s not …

BTW, should be noted that the need to issue a cache line lock on x86 does seem to slow down 128-bit CAS quite a bit on x86-64 platforms. On arm64, there's no reason to skimp with a…

You can use a 64-bit CAS if you want to use a 32-bit epoch and a pointer compression scheme of any kind, or just a 32-bit index into regions that are thread specific. I think I did…

Yes, I meant to clarify the memory model discussion; I had tried to simplify and did a poor job; I got similar feedback after it was published, and never remembered to get to it. W…

So that work came after mine, and seems to be a FIFO not a ring buffer. The library I built at the time also had FIFOs and LIFOs that were tweaks on previous algorithms, but nothin…

I don't think I even saw this until I published the article. I don't think it was academically published, or googled well back in 2000. Nor did it match my needs for a ring buffer …

Well, when I was doing the original work on it (about 5 years ago now), I spent a lot of time trying to find something else in the literature. I couldn't find anything that wasn't …

Agreed that this is not a critical problem, and the cooperative side channel can be useful in otherwise uncooperative environments. The article does mention wanting to coordinate a…

By the way, the run-time type checking is one of the use cases where I really would like to have a tractable interface for hashing at compile time, preventing unbounded strcmps, an…

Oh, this is very good. Some of the stuff you're doing in the library I've also been doing recently, and has been working well, like using the string of the type name to allow for r…

No, should have said '50'. Have fixed that, thanks.

From my read, that article doesn't have anything in it that isn't standards compliant C. My memory is getting worse as I get older, but I'd say by C17 all that was standard, and de…

It is-- if you click in to their full list, you should see it near the top in their "above the water" section, under `#pragma once`. I suspect it was added after the meme image was…

To be clear, the example I provided for the other person explains the bit you're missing where the names aren't working... if you carefully follow the rules, the # and ## operators…

If my google fu is that bad, it's pretty much impossible to be.

Thanks. Also, per another person in the thread, here are the two annotations he or she was asking for, heavily annotated. They are both only a couple lines, but it deals with thing…

Okay, finally found some time to provide you with a fully annotated example of your original ask here, assuming you wanted to transform the arguments passed to F into IDs, and the …

If you can give me specifics on how it's not clear, I'd very much want to improve it. Please DM me about it.

Yes, 100%. And since CPP doesn't actually understand C, it's not too hard to do some lightweight preprocessing that requires some real additional parsing. But while CPP is pretty f…

Well, I've done it that way if I'm willing to limit myself to pointers or ints up to a pointer size, but that doesn't work with floats or doubles, for instance. Ergonomically, I ha…

Wow, you are a braver person than I. Well done.
