- 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
#include
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
#include
int main() {
std::tuple 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
#include
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,
#1345, #1347, #1349, #1354, #1362, #1366, #1364, #1370,
#1371, #1385, #1388, #1397, #1414, #1416, #1422, #1427,
#1431, #1433)
