- Update to version 7.1.0
* Switched from Grisu3 to Dragonbox for the default
floating-point formatting which gives the shortest decimal
representation with round-trip guarantee and correct rounding.
This makes {fmt} up to 20-30x faster than common
implementations of std::ostringstream and sprintf on
dtoa-benchmark and faster than double-conversion and Ryū. It
is possible to get even better performance at the cost of
larger binary size by compiling with the
FMT_USE_FULL_CACHE_DRAGONBOX macro set to 1.
* Added an experimental unsynchronized file output API which,
together with format string compilation can give 5-9 times
speed up compared to fprintf on common platforms.
* Added a formatter for std::chrono::time_point<system_clock>
* Added support for ranges with non-const begin/end to fmt::join
* Added a memory_buffer::append overload that takes a range.
* Improved handling of single code units in FMT_COMPILE.
* Added dynamic width support to format string compilation.
* Improved error reporting for unformattable types: now you'll
get the type name directly in the error message instead of
the note.
* Added the make_args_checked function template that allows
you to write formatting functions with compile-time format
string checks and avoid binary code bloat.
* Replaced snprintf fallback with a faster internal IEEE 754
float and double formatter for arbitrary precision.
* Made format_to_n and formatted_size part of the core API.
* Added fmt::format_to_n overload with format string
compilation.
* Added fmt::format_to overload that take text_style.
* Made the # specifier emit trailing zeros in addition to the
decimal point.
* Changed the default floating point format to not include .0
for consistency with std::format and std::to_chars. It is
possible to get the decimal point and trailing zero with the
# specifier.
* Fixed an issue with floating-point formatting that could
result in addition of a non-significant trailing zero in
rare cases e.g. 1.00e-34 instead of 1.0e-34.
* Made fmt::to_string fallback on ostream insertion operator
if the formatter specialization is not provided.
* Added support for the append mode to the experimental file
API and improved fcntl.h detection.
* Fixed handling of types that have both an implicit
conversion operator and an overloaded ostream insertion
operator.
* Fixed a slicing issue in an internal iterator type.
* Fixed an issue in locale-specific integer formatting.
* Fixed handling of exotic code unit types.
* Improved FMT_ALWAYS_INLINE.
* Improved documentation.
* Added the FMT_REDUCE_INT_INSTANTIATIONS CMake option that
reduces the binary code size at the cost of some integer
formatting performance. This can be useful for extremely
memory-constrained embedded systems.
* Added the FMT_USE_INLINE_NAMESPACES macro to control usage
of inline namespaces.
* Improved build configuration.
* Fixed various warnings and compilation issues.
- Add fmt-7.1.0-LTO.patch
OBS-URL: https://build.opensuse.org/request/show/844381
OBS-URL: https://build.opensuse.org/package/show/devel:libraries:c_c++/fmt?expand=0&rev=33
- Update to version 7.0.1
* Updated the inline version namespace name.
* Worked around a gcc bug in mangling of alias templates
* Fixed minor issues with the documentation.
- Update to version 7.0.0
* Reduced the library size.
* Added a simpler and more efficient format string compilation
API. The old fmt::compile API is now deprecated.
* Optimized integer formatting: format_to with format string
compilation and a stack-allocated buffer is now faster than
to_chars on both libc++ and libstdc++.
* Optimized handling of small format strings.
* Applied extern templates to improve compile times when using
the core API and fmt/format.h. It is still recommended to use
fmt/core.h instead of fmt/format.h but the compile time
difference is now smaller.
* Named arguments are now stored on stack (no dynamic memory
allocations) and the compiled code is more compact and
efficient.
* Implemented compile-time checks for dynamic width and
precision.
* Added sentinel support to fmt::join.
* Added support for named args, clear and reserve to
dynamic_format_arg_store.
* Added support for the 'c' format specifier to integral types
for compatibility with std::format.
* Replaced the 'n' format specifier with 'L' for compatibility
with std::format. The 'n' specifier can be enabled via the
FMT_DEPRECATED_N_SPECIFIER macro.
* The '=' format specifier is now disabled by default for
compatibility with std::format. It can be enabled via the
FMT_DEPRECATED_NUMERIC_ALIGN macro.
* Removed the following deprecated APIs:
+ FMT_STRING_ALIAS and fmt macros - replaced by
FMT_STRING
+ fmt::basic_string_view::char_type - replaced by
fmt::basic_string_view::value_type
+ convert_to_int

+ *parse_context - replaced by *format_parse_context
+ FMT_DEPRECATED_INCLUDE_OS
+ FMT_DEPRECATED_PERCENT - incompatible with
std::format
+ *writer - replaced by compiled format API
* Renamed the internal namespace to detail. The former is
still provided as an alias if the FMT_USE_INTERNAL macro is
defined.
* Improved compatibility between fmt::printf with the standard
specs.
* Fixed handling of operator<< overloads that use copyfmt.
* Added the FMT_OS CMake option to control inclusion of
OS-specific APIs in the fmt target. This can be useful for
embedded platforms.
* Replaced FUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION with the
FMT_FUZZ macro to prevent interferring with fuzzing of
projects using {fmt}.
* Fixed compatibility with emscripten.
* Improved documentation.
* Implemented various build configuration fixes and
improvements.
* Fixed various warnings and compilation issues.

a non-formattable type:
* Reduced library size by ~10%.
* Always print decimal point if # is specified (#1476, #1498):
* Implemented the 'L' specifier for locale-specific numeric
formatting to improve compatibility with std::format. The 'n'
specifier is now deprecated and will be removed in the next
major release.
* Moved OS-specific APIs such as windows_error from
fmt/format.h to fmt/os.h. You can define
FMT_DEPRECATED_INCLUDE_OS to automatically include fmt/os.h from
fmt/format.h for compatibility but this will be disabled in the
next major release.

- Update to version 6.1.2
* Fixed ABI compatibility with libfmt.so.6.0.0 (#1471).
* Fixed handling types convertible to std::string_view (#1451).
Thanks @denizevrenci (Deniz Evrenci).
* Made CUDA test an opt-in enabled via the FMT_CUDA_TEST CMake
option.
* Fixed sign conversion warnings (#1440). Thanks @0x8000-0000
(Florin Iucha).
- Update to version 6.1.1
* Added a missing decimal point in exponent notation with
trailing zeros.
* Removed deprecated format_arg_store::TYPES.
- Update to version 6.1.0
* {fmt} now formats IEEE 754 ``float`` and ``double`` using
the shortest decimal representation with correct rounding by
default:
.. code:: c++
#include <cmath>
#include <fmt/core.h>
int main() {
fmt::print("{}", M_PI);
}
prints ``3.141592653589793``.
* Made the fast binary to decimal floating-point formatter the
default, simplified it and improved performance. {fmt} is now
15 times faster than libc++'s ``std::ostringstream``, 11
times faster than ``printf`` and 10% faster than
double-conversion on `dtoa-benchmark
(https://github.com/fmtlib/dtoa-benchmark)
================== ========= =======
Function Time (ns) Speedup
================== ========= =======
ostringstream 1,346.30 1.00x
ostrstream 1,195.74 1.13x
sprintf 995.08 1.35x
doubleconv 99.10 13.59x
fmt 88.34 15.24x
================== ========= =======
* {fmt} no longer converts ``float`` arguments to ``double``.
In particular this improves the default (shortest)
representation of floats and makes
``fmt::format`` consistent with ``std::format`` specs
(#1336, #1353, #1360, #1361)
.. code:: c++
fmt::print("{}", 0.1f);
prints ``0.1`` instead of ``0.10000000149011612``.
* Made floating-point formatting output consistent with
``printf``/iostreams (#1376, #1417)
* Added support for 128-bit integers (#1287)
.. code:: c++
fmt::print("{}", std::numeric_limits<__int128_t>::max());
prints ``170141183460469231731687303715884105727``.
* The overload of ``print`` that takes ``text_style`` is now
atomic, i.e. the output from different threads doesn't
interleave (#1351)
* Made compile time in the header-only mode ~20% faster by
reducing the number of template instantiations. ``wchar_t``
overload of ``vprint`` was moved from
``fmt/core.h`` to ``fmt/format.h``.
* Added an overload of ``fmt::join`` that works with tuples
(#1322, #1330)
.. code:: c++
#include <tuple>
#include <fmt/ranges.h>
int main() {
std::tuple<char, int, float> t{'a', 1, 2.0f};
fmt::print("{}", t);
}
prints ``('a', 1, 2.0)``.
* Changed formatting of octal zero with prefix from "0o0" to
"0":
.. code:: c++
fmt::print("{:#o}", 0);
prints ``0``.
* The locale is now passed to ostream insertion (``<<``)
operators (#1406)
.. code:: c++
#include <fmt/locale.h>
#include <fmt/ostream.h>
struct S {
double value;
};
std::ostream& operator<<(std::ostream& os, S s) {
return os << s.value;
}
int main() {
auto s = fmt::format(std::locale("fr_FR.UTF-8"), "{}", S{0.42});
// s == "0,42"
}
* Locale-specific number formatting now uses grouping (#1393,
#1394)
* Fixed handling of types with deleted implicit rvalue
conversion to ``const char**`` (#1421)
.. code:: c++
struct mystring {
operator const char*() const&;
operator const char*() &;
operator const char*() const&& = delete;
operator const char*() && = delete;
};
mystring str;
fmt::print("{}", str); // now compiles
* Enums are now mapped to correct underlying types instead of
``int`` (#1286)
* Enum classes are no longer implicitly converted to ``int``
(#1424)
* Added ``basic_format_parse_context`` for consistency with
C++20 ``std::format`` and deprecated ``basic_parse_context``.
* Fixed handling of UTF-8 in precision (#1389, #1390)
* Added a CUDA test (#1285, #1317)
* Improved documentation (#1276, #1291, #1296, #1315, #1332,
#1337, #1395, #1418)
* Various code improvements (#1358, #1407)
* Fixed compile-time format string checks for user-defined
types (#1292)
* Worked around a false positive in
``unsigned-integer-overflow`` sanitizer (#1377)
* Fixed various warnings and compilation issues (#1273, #1278,
#1280, #1281, #1288, #1290, #1301, #1305, #1306, #1309,
#1312, #1313, #1316, #1319, #1320, #1326, #1328, #1344,
