Implement P2328R1 `join_view` Should Join All Views Of Ranges by miscco · Pull Request #2038 · microsoft/STL

miscco · 2021-07-03T12:02:06Z

Fixes #1985

I am still baffled why array<string, 5>{{{}, "Hello ", {}, "World!", {}}} | views::join was not fixed 😿

Fixes microsoft#1985

Derp, I did not update the can_test boolean that enables the test...

I am still baffled why array<string, 5>{{{}, "Hello ", {}, "World!", {}}} | views::join was not fixed 😿

I see nothing to fix, other than perhaps making array a view?

I also note that the paper title is incorrectly transcribed.

I also note that the paper title is incorrectly transcribed.

I'm tempted to veto the Stephan-casing of the title; "Views of Ranges" doesn't have the same meaning as the intended "views of ranges". @StephanTLavavej, could you live with "P2328R11 join_view Should Join All views Of ranges"?

Remove extraneous blank line.

@miscco FYI I pushed a change that removed all of the _Dummy members from the optional-alike types in <ranges>. We don't need them in C++20, since we can get away with initializing no union member even in a constexpr constructor.

StephanTLavavej

Looks good to me, after @timsong-cpp's comments are addressed.

miscco · 2021-08-05T14:08:56Z

@timsong-cpp I think I managed to get it working as you suggested.

StephanTLavavej

Looks good, I'll push a trivial change to take (int) instead of (const int).

StephanTLavavej · 2021-08-07T00:22:04Z

FYI @CaseyCarter, @miscco and I pushed changes after you approved.

StephanTLavavej · 2021-08-09T22:08:55Z

Mirrored to internal MSVC-PR-343332. Please notify me if any further changes are pushed to this branch.

StephanTLavavej · 2021-08-09T23:54:03Z

@miscco @CaseyCarter This failed in the internal test harness so I had to drop the || defined(MSVC_INTERNAL_TESTING) logic.
