This is probably the most compelling example of C++ reflection I've seen yet. Deriving a debug printer or stringifying the names of enums is one thing, but this is clearly quite a powerful abstraction one could get 'for free'

It's a bit heavy handed, but the VSCode "Live Server" plugin is the closest I've come. If I set code as the default file association for `.html`, then it's just one extra click to get it open in a browser with a loc

I mean, we already have a sort-of answer, because the "Bedrock Edition" of Minecraft is written in C++, and it is indeed less popular on PC (on console, it's the only option, so _overall_ it might win out) and does lack any r

I still think it is a shame that `match` isn't valid as an expression, requiring things like the helper function here that could be a lambda or part of a comprehension otherwise

No idea how plug-n-playable it is, but the source seems to be self contained: https://github.com/mcy/mcy.github.io/blob/master/public/js/m...

Note that MinGW uses libwinpthread, which is known to have slow TLS behavior anyway (I've observed a 100% overhead compared to running the same program under WSL using a linux-native GCC). c.f. https://github.com/msys2&

I can't find the exact link now (very well might have been a video without a searchable transcript), but I recall someone asking Linus that (specifically re his previous comments on C++), and his answer was something like he saw Rust s

“strict aliasing” refers to disallowing pointers of different types to alias. In the context of a function that accepts two arrays of floats, for example, it doesn’t apply

Some other languages have equivalents (OCaml comes to mind), but usually they’re less necessary

I mean, maybe? But if you hover over the function you just completed, the same LSP will also show you the documentation. This is how I personally use it for discovery, anyway. The other day I was writing some Rust code and needed to remove

One of my first ever public projects actually had a bug report that ended up being the Turkish i problem. Didn’t know there were more!

The Fn trait could be used, which prevents mutation, but allows a lot of useful closures. I should note, a motivated user could provide a junk function no matter what the type accepted is

Is there a technical reason to now allow closures as the integrand?

It seems like it is lacking the functionality R's integrate has for handling infinite boundaries, but I suppose you could implement that yourself on the outside. For what it's worth, use integrate::adaptive_quadrature::simps

I’d be shocked if jart didn’t know this, but it seems unlikely that an LLM would generate one of these most vexing parses, unless explicitly asked

I wonder how much of this has to do with Covid interrupting a lot of recent grads’ time in college and forcing a large percentage of their courses to be online for a time It seems pretty obvious to me that the quality of both teaching and a

It’s sadly a bit more of a proof of concept than a hackable project. The docker build in the readme did work last time I tried, and there is a demo site at https://jprendes.github.io/emception/ , but I’ve failed to modi

If what I want is not an executable but a shared library, does this get me anything? I currently have a use case that uses a server running an emscripten build (using SMODULARIZE and some exports, I suppose it’s not a true dylib)

The closest I’ve found in terms of description is https://github.com/feschber/lan-mouse , but the lack of encryption on the connection has discouraged me from using it. I’m also a paid Synergy user, and it’s frankly com

It seems a little odd to me that this is not just… a vscode extension pack?

I think a challenge to this evolution path is the same as what motivated Sutter’s cpp2: defaults I think the premise that a lot of experienced programmers can write good C++ is at least somewhat valid. They know to not use raw pointers, whi

extern “C” on everything, if you care about linking compatibility, gets you another chunk of the way there by also disabling overloading etc.

I feel like most RAII fans will openly admit that it’s the worst name in the world for such an idea. The idea is that any time you acquire a resource, you should initialize an object with said resource. But I guess “resource allocation shou

If you’re very careful with forward-vs-back slashes and your username isn’t “Firstname Lastname”, sure. But in practice there are tons of issues especially for non expert users
