Fixes#2952. The testsuite indirectly called strftime() with conversion
specifiers defined only in C99. In MSVCRT this function conforms only to
C89. Only in the updated UCRT this functon provides the functionality of
C99.
* Implement range_formatter and format_kind
* Attempted gcc 4.8 fix
* gcc 4.8 interprets inaccessible as a hard error (instead of... not available)
* Attempting to delete set_debug_format.
* clang-format
* Different implementation of FMT_STATICALLY_WIDEN
* Renaming copy_str_range to copy_str.
* I guess I need a definition
* Forgot to delete these.
* Other PR comments.
* 2954: Add test case
* Eliminate extra-test and merge it into existing std-test instead. Add conditionals for filesystem::path testing that does not run into the ambiguity problem.
* #2968: Introduce additional compile-time predicate to detect recursive ranges and reject them in formatter specialization for ranges. In addition, introduce additional wrapper traits for the individual logical operands of the complete range constraints
* #2968: Eliminate preprocessor condition that enables the formatter specialization for std::filesystem::path
* #2968: Eliminate preprocessor condition that enables the test for the formatter specialization for std::filesystem::path
* Use own bool_constant, which is available for all C++ versions
* Reintroduce previous workaround but restrict to VS 2015 for now
* Comma fix
* - Rename is_not_recursive_range to is_nonrecursive_range and add comment that explains it being depending on is_range being true
- Merge has_fallback_formatter_delayed into is_formattable_delayed and add comment that explains it being depending on is_not_recursive_range being true
- Replace disjunction in formatter specialization by has_fallback_formatter_delayed
- Get rid of unneeded detail:: prefixes within namespace detail
* #2954: Provide std::conjunction and std::disjunction substitutes
* #2954: Use conjunction and disjunction substitute to make formatter specializations for ranges and maps more robust (especially for Visual Studio compiler family)
* #2954: As workaround for older MSVC compilers split formatter<std::filesystem::path> partial template specialization into two explicit specialization.
* 2954: Add test case
* Provide simplified implementations of conjunction and disjunction
* Remove workaround explicit specializations if the partial specialization would cause an ambiguity error
* Eliminate extra-test and merge it into existing std-test instead. Add conditionals for filesystem::path testing that does not run into the ambiguity problem.
Add support for 'std::variant' in C++17.
For C++17, if all the alternatives of a variant are formattable
the variant is now also formattable. In addition 'std::monostate'
is now formattable.
Moves implementation into 'std.h', and tests into 'std-test.cc'.
Avoid fold-expression since MSVC was crashing.
Add section for 'fmt/std.h' in API-docs.
