Re: [webkit-dev] Using C++20 in WebKit

2022-01-21 Thread Alex Christensen via webkit-dev 
Related to the C++20 change, I’m working on moving the Visual Studio build to 
Visual Studio 2022.  I’ve informed several involved parties directly, but now 
I’ve informed everyone.  If anyone has a reason not to move to VS2022, please 
let me know.

 As a result, we can use some of C++20 features.
 I wonder if we can flip C++20 now. While some of C++20 features cannot
 be used since GCC 8.3.0 does not support, but some of features can be
 used, and it is super useful.

It sounds nice! New CMake (3.21~) already supports VS 2022.

 From the PoV of WebKitGTK I think it is Ok to enable now the building
 with C++-20 support and to start using the C++-20 features already
 supported by GCC 8.3.0
 
 Check here: https://gcc.gnu.org/projects/cxx-status.html 
  which C++-20
 features are supported by GCC 8
 
 Before using them I think it would be a good idea to double-check if
 those are also supported by the minimum version of Clang that we want to
 support.
 And maybe also to check if those are supported by MS Visual C++ ?
 I say maybe because I'm not sure if we support this compiler.

Re: [webkit-dev] Using C++20 in WebKit

2022-01-21 Thread Alex Christensen via webkit-dev 
While we’re updating things, is there any objection to updating the minimum 
version of CMake required?  Right now it is 3.12, which was released in 2018.  
Does anyone have any limitations we should consider when picking a new minimum 
version?
