Bug ID: 106201
Summary: filesystem::directory_iterator is a borrowable range?
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: prlw1 at cam dot ac.uk
Target Milestone: ---
In the following:
#include <algorithm>
#include <filesystem>
#include <iostream>
#include <ranges>
int main()
{
auto print = [](const auto& x) {std::cout << x << '\n';} ;
std::ranges::for_each(
std::views::iota(1) | std::views::take(5),
print
);
std::ranges::for_each(
std::filesystem::directory_iterator("/"),
print
);
std::ranges::for_each(
std::filesystem::directory_iterator("/") | std::views::take(3),
print
);
}
the first two for_each clauses compile and execute correctly, even with g++
10.3.0.
Is my expectation that the third clause is valid incorrect?
(I just tried with today's head, g++ (GCC) 13.0.0 20220705 (experimental) and
it failed to compile.)
Oh: https://cplusplus.github.io/LWG/issue3480
But: it says "could be fixed ... (as libstdc++ currently does anyway)"
Issue looks resolved?
Thoughts?
