You can move the code, sure. It's the infrastructure that is hard to relocate (issues, pulls). If one uses references like `#123` in the history, you need to do something to keep them "alive" on a migration. GitLab itself has

I noticed this when I went to RPI (I graduated HS in 2007). My high school wasn't ranked at all (or at least no one cared where it was ranked) and AP courses weren't offered until after I graduated. Based on reports from my younge

Hmm. I see issues about finding executable-but-not-readable files, but nothing about `access(X_OK)` specifically (though GitLab's search may be failing here). Anyways, there are a number of…unfortunate behaviors that are baked in too d

If you're never using any external dependencies, it can work. It's just the no-dep C projects are few and far between. As soon as you have things like dependencies or compiler detection, CMake or other build systems really start p

Sure, but I also prefer talking directly about what you're talking about though. If you have some Windows implementations that need to talk to each other, I'd rather they use HANDLE and HMODULE than "void* winkwinknudgenudge&

Modules don't have search paths unless you toss everything into one directory. The robust way is to instead do `-fmodule-path=modname=path/to/bmi` where ambiguity is non-existent. It is IFNDR to have two modules of the same n

Because `void*` to pass `HANDLE` around is better how? Maybe if you're able to hermetically seal off platform-specific bits, but usually you'll have two parts that want to talk about Windows API types across their call boundaries…

Clang modules were basically "let's try to automate precompiled headers". It lacks the isolation offered by proper modules. Even if they're not faster, the isolation is something I'm looking forward to.

FWIW, the `#embed`/`std::embed` proposal is the preferable solution here. There's a lot of time spent in the compiler parsing those ASCII floats into bytes (and I've seen `clang-format` take ages to format a block of `0xXX`

Indeed. Mismatching headers and libraries is not all that rare. I've seen headers found from Homebrew, libraries from the macOS SDK, and some related tool from `/usr`. Things…rarely work out well, but you only find out in your tes

I'm speculating, but I think that if one enforced "module is a namespace", projects like Qt, standard libraries, and other libraries would be forced to ignore them for far longer than anyone wants due to ABI stability require

That is only if you have a global module fragment. Without that, you can start right off with `export module M;`.

There are new rules about "reachability" and "module linkage". Not to mention things like methods defined within the class declaration are no longer as-if `inline` when within a module. It's not just "a faster

The implementations have no agreement here. Clang "likes" `.cppm` while MSVC "likes" `.ixx`. I don't think there's any hope for agreement on extensions.

Probably because things that don't get "used" can still affect things. There's a lot of detail in name lookup algorithms and SFINAE where computing what you end up using and giving each TU its own view is probably not mu

Unlikely to be fixed. The module files are basically AST dumps and no compiler keeps that stable over time. Even flag selections make incompatible BMIs. So if one TU uses C++20 and another uses C++23, they'll each need their own BMI of
