值得一提的是, 除了format库以外,fmtlib还封装了chrono库和 包含一个ranges.h的库。 不过ranges.h只写了600行,就实现了个join函数,基本上相当于滥竽充数,而chrono库也只写了2000行,并且写的比较丑,只能简单拿来用用和标准库的质量是比不了的。 总而言之fmtlib只建议使用format部分,其他部分的代码没什么质量,...

Repro: #include "fmt/chrono.h" int main() { using namespace std::literals::chrono_literals; auto args = fmt::make_format_args(5s); } The warning was introduced in this PR: #2971
fmtlib还封装了chrono库和ranges.h库，前者提供了时间相关的功能，后者简化了字符串组合操作。然而，ranges.h的实现较为简略，只能满足基本需求，而chrono库的代码量也相对有限，设计相对粗糙。综上所述，fmtlib推荐使用其format部分，该部分功能强大、易用。而其他封装的库在实现质量和标准库相比，还有提升...

The double bind of desire between chronophobia, the fear of time, and chronophilia, the desire of a temporal being, is considered. The author argues that chronophobia and chronophilia are two aspects of the same condition. The distinction ...

With C++20 we can format all the std::chrono types using std::format, e.g., the following program #include <iostream> #include <chrono> #include <format> int main() { std::chrono::utc_time<std::chrono::nanoseconds> ts = std::chrono::utc_...

Hello I think this is a regression (judging by #1004 and #1012). #include <fmt/chrono.h> int main(int argc, char* argv[]) { std::chrono::duration<double, std::nano> a { 46.666667 }; fmt::print("{}\n", a); fmt::print("{:.0}\n", a); fmt::p...
