9.1.0 - 2022-08-27
------------------
* ``fmt::formatted_size`` now works at compile time
(`#3026
`_). For example
(`godbolt `__):
.. code:: c++
#include
int main() {
using namespace fmt::literals;
constexpr size_t n = fmt::formatted_size("{}"_cf, 42);
fmt::print("{}\n", n); // prints 2
}
Thanks `@marksantaniello (Mark Santaniello)
`_.
* Fixed handling of invalid UTF-8
(`#3038 `_,
`#3044 `_,
`#3056 `_).
Thanks `@phprus (Vladislav Shchapov) `_ and
`@skeeto (Christopher Wellons) `_.
* Improved Unicode support in ``ostream`` overloads of ``print``
(`#2994 `_,
`#3001 `_,
`#3025 `_).
Thanks `@dimztimz (Dimitrij Mijoski) `_.

(`#2994 `_).
Thanks `@phprus (Vladislav Shchapov) `_.

auto v = std::vector{1, 2, 3};
fmt::print("{:n}\n", v); // prints 1, 2, 3
}
Thanks `@BRevzin (Barry Revzin) `_.

9.0.0 - 2022-07-04
------------------
* Switched to the internal floating point formatter for all decimal presentation
formats. In particular this results in consistent rounding on all platforms
and removing the ``s[n]printf`` fallback for decimal FP formatting.
* Compile-time floating point formatting no longer requires the header-only
mode. For example (`godbolt `__):
.. code:: c++
#include
#include
consteval auto compile_time_dtoa(double value) -> std::array {
auto result = std::array();
fmt::format_to(result.data(), FMT_COMPILE("{}"), value);
return result;
}
constexpr auto answer = compile_time_dtoa(0.42);
works with the default settings.
* Improved the implementation of
`Dragonbox `_, the algorithm used for
the default floating-point formatting
(`#2713 `_,
`#2750 `_).
Thanks `@jk-jeon (Junekey Jeon) `_.
* Made ``fmt::to_string`` work with ``__float128``. This uses the internal
FP formatter and works even on system without ``__float128`` support in
``[s]printf``.
* Disabled automatic ``std::ostream`` insertion operator (``operator<<``)
discovery when ``fmt/ostream.h`` is included to prevent ODR violations.
You can get the old behavior by defining ``FMT_DEPRECATED_OSTREAM`` but this
will be removed in the next major release. Use ``fmt::streamed`` or
``fmt::ostream_formatter`` to enable formatting via ``std::ostream`` instead.
* Added ``fmt::ostream_formatter`` that can be used to write ``formatter``
specializations that perform formatting via ``std::ostream``.
For example (`godbolt `__):
.. code:: c++
#include
struct date {
int year, month, day;
friend std::ostream& operator<<(std::ostream& os, const date& d) {
return os << d.year << '-' << d.month << '-' << d.day;
}
};
template <> struct fmt::formatter : ostream_formatter {};
std::string s = fmt::format("The date is {}", date{2012, 12, 9});
// s == "The date is 2012-12-9"
* Added the ``fmt::streamed`` function that takes an object and formats it
via ``std::ostream``.
For example (`godbolt `__):
.. code:: c++
#include
#include
int main() {
fmt::print("Current thread id: {}\n",
fmt::streamed(std::this_thread::get_id()));
}
Note that ``fmt/std.h`` provides a ``formatter`` specialization for
``std::thread::id`` so you don't need to format it via ``std::ostream``.
* Deprecated implicit conversions of unscoped enums to integers for consistency
with scoped enums.
* Added an argument-dependent lookup based ``format_as`` extension API to
simplify formatting of enums.
* Added experimental ``std::variant`` formatting support
(`#2941 `_).
For example (`godbolt `__):
.. code:: c++
#include
#include
int main() {
auto v = std::variant(42);
fmt::print("{}\n", v);
}
prints::
variant(42)
Thanks `@jehelset `_.
* Added experimental ``std::filesystem::path`` formatting support
(`#2865 `_,
`#2902 `_,
`#2917 `_,
`#2918 `_).
For example (`godbolt `__):
.. code:: c++
#include
#include
int main() {
fmt::print("There is no place like {}.", std::filesystem::path("/home"));
}
prints::
There is no place like "/home".
Thanks `@phprus (Vladislav Shchapov) `_.
* Added a ``std::thread::id`` formatter to ``fmt/std.h``.
For example (`godbolt `__):
.. code:: c++
#include
#include
int main() {
fmt::print("Current thread id: {}\n", std::this_thread::get_id());
}
* Added ``fmt::styled`` that applies a text style to an individual argument
(`#2793 `_).
For example (`godbolt `__):
.. code:: c++
#include
#include
int main() {
auto now = std::chrono::system_clock::now();
fmt::print(
"[{}] {}: {}\n",
fmt::styled(now, fmt::emphasis::bold),
fmt::styled("error", fg(fmt::color::red)),
"something went wrong");
}
prints

Thanks `@rbrugo (Riccardo Brugo) `_.
* Made ``fmt::print`` overload for text styles correctly handle UTF-8
(`#2681 `_,
`#2701 `_).
Thanks `@AlexGuteniev (Alex Guteniev) `_.
* Fixed Unicode handling when writing to an ostream.
* Added support for nested specifiers to range formatting
(`#2673 `_).
For example (`godbolt `__):
.. code:: c++
#include
#include
int main() {
fmt::print("{::#x}\n", std::vector{10, 20, 30});
}
prints ``[0xa, 0x14, 0x1e]``.
Thanks `@BRevzin (Barry Revzin) `_.
* Implemented escaping of wide strings in ranges
(`#2904 `_).
Thanks `@phprus (Vladislav Shchapov) `_.
* Added support for ranges with ``begin`` / ``end`` found via the
argument-dependent lookup
(`#2807 `_).
Thanks `@rbrugo (Riccardo Brugo) `_.
* Fixed formatting of certain kinds of ranges of ranges
(`#2787 `_).
Thanks `@BRevzin (Barry Revzin) `_.
* Fixed handling of maps with element types other than ``std::pair``
(`#2944 `_).
Thanks `@BrukerJWD (Jonathan W) `_.
* Made tuple formatter enabled only if elements are formattable
(`#2939 `_,
`#2940 `_).
Thanks `@jehelset `_.
* Made ``fmt::join`` compatible with format string compilation
(`#2719 `_,
`#2720 `_).
Thanks `@phprus (Vladislav Shchapov) `_.
* Made compile-time checks work with named arguments of custom types and
``std::ostream`` ``print`` overloads
(`#2816 `_,
`#2817 `_,
`#2819 `_).
Thanks `@timsong-cpp `_.
* Removed ``make_args_checked`` because it is no longer needed for compile-time
checks (`#2760 `_).
Thanks `@phprus (Vladislav Shchapov) `_.
* Removed the following deprecated APIs: ``_format``, ``arg_join``,
the ``format_to`` overload that takes a memory buffer,
``[v]fprintf`` that takes an ``ostream``.
* Removed the deprecated implicit conversion of ``[const] signed char*`` and
``[const] unsigned char*`` to C strings.
* Removed the deprecated ``fmt/locale.h``.
* Replaced the deprecated ``fileno()`` with ``descriptor()`` in
``buffered_file``.
* Moved ``to_string_view`` to the ``detail`` namespace since it's an
implementation detail.
* Made access mode of a created file consistent with ``fopen`` by setting
``S_IWGRP`` and ``S_IWOTH``
(`#2733 `_).
Thanks `@arogge (Andreas Rogge) `_.
* Removed a redundant buffer resize when formatting to ``std::ostream``
(`#2842 `_,
`#2843 `_).
Thanks `@jcelerier (Jean-Michaël Celerier) `_.
* Made precision computation for strings consistent with width
(`#2888 `_).
* Fixed handling of locale separators in floating point formatting
(`#2830 `_).
* Made sign specifiers work with ``__int128_t``
(`#2773 `_).
* Improved support for systems such as CHERI with extra data stored in pointers
(`#2932 `_).
Thanks `@davidchisnall (David Chisnall) `_.
* Improved documentation
(`#2706 `_,
`#2712 `_,
`#2789 `_,
`#2803 `_,
`#2805 `_,
`#2815 `_,
`#2924 `_).
