fmtlib: updated to 10.2.1
10.2.1 - 2024-01-03
- Fixed ABI compatibility with earlier 10.x versions
10.2.0 - 2024-01-01
- Added support for the `%j` specifier (the number of days) for
`std::chrono::duration`
- Added support for the chrono suffix for days and changed
the suffix for minutes from "m" to the correct "min"
For example ([godbolt](https://godbolt.org/z/9KhMnq9ba)):
```c++
#include <fmt/chrono.h>
int main() {
fmt::print("{}\n", std::chrono::days(42)); // prints "42d"
}
```
- Fixed an overflow in `std::chrono::time_point` formatting with large dates
- Added a formatter for `std::source_location`
For example ([godbolt](https://godbolt.org/z/YajfKjhhr)):
```c++
#include <source_location>
#include <fmt/std.h>
int main() {
fmt::print("{}\n", std::source_location::current());
}
```
prints
```
/app/example.cpp:5:51: int main()
```
- Added a formatter for `std::bitset`
```c++
#include <bitset>
#include <fmt/std.h>
int main() {
fmt::print("{}\n", std::bitset<6>(42)); // prints \
"101010"
}
```
- Added an experimental `nested_formatter` that provides an easy way of
applying a formatter to one or more subobjects while automatically handling
width, fill and alignment. For example:
```c++
#include <fmt/format.h>
struct point {
double x, y;
};
template <>
struct fmt::formatter<point> : nested_formatter<double> {
auto format(point p, format_context& ctx) const {
return write_padded(ctx, [=](auto out) {
return format_to(out, "({}, {})", nested(p.x), nested(p.y));
});
}
};
int main() {
fmt::print("[{:>20.2f}]", point{1, 2});
}
```
prints
```
[ (1.00, 2.00)]
```
- Added the generic representation (`g`) to `std::filesystem::path`
```c++
#include <filesystem>
#include <fmt/std.h>
int main() {
fmt::print("{:g}\n", std::filesystem::path("C:\\foo"));
}
```
prints `"C:/foo"` on Windows.
- Made `format_as` work with references
- Fixed formatting of invalid UTF-8 with precision
- Fixed an inconsistency between `fmt::to_string` and `fmt::format`
- Disallowed unsafe uses of `fmt::styled`
```c++
auto s = fmt::styled(std::string("dangle"), fmt::emphasis::bold);
fmt::print("{}\n", s); // compile error
```
Pass `fmt::styled(...)` as a parameter instead.
- Added a null check when formatting a C string with the `s` specifier
- Disallowed the `c` specifier for `bool`
- Made the default formatting unlocalized in `fmt::ostream_formatter` for
consistency with the rest of the library
- Fixed localized formatting in bases other than decimal
- Fixed a performance regression in experimental `fmt::ostream::print`
- Added synchronization with the underlying output stream when writing to
the Windows console
- Changed to only export `format_error` when {fmt} is built as a shared
library
- Made `fmt::streamed` `constexpr`.
- Enabled `consteval` on older versions of MSVC
- Added an option to build without `wchar_t` support on Windows
- Improved build and CI configuration
- Fixed various warnings, compilation and test issues
- Improved documentation and README
- Updated CI dependencies

Log message:
fmtlib: update to 10.0.0.
10.0.0 - 2023-05-09
-------------------
* Replaced Grisu with a new floating-point formatting algorithm for given
precision
The new algorithm is based on Dragonbox already used for the
shortest representation and gives substantial performance improvement:
* Replaced ``snprintf``-based hex float formatter with an internal
implementation
This removes the last usage of ``s(n)printf`` in {fmt}.
* Fixed alignment of floating-point numbers with localization
* Improved C++20 module support
Switched to the `modules CMake library <https://github.com/vitaut/modules>`_
which allows building {fmt} as a C++20 module with clang::
CXX=clang++ cmake -DFMT_MODULE=ON .
make
* Made ``format_as`` work with any user-defined type and not just enums.
For example (`godbolt <https://godbolt.org/z/b7rqhq5Kh>`__):
.. code:: c++
#include <fmt/format.h>
struct floaty_mc_floatface {
double value;
};
auto format_as(floaty_mc_floatface f) { return f.value; }
int main() {
fmt::print("{:8}\n", floaty_mc_floatface{0.42}); // prints \
" 0.42"
}
* Removed deprecated implicit conversions for enums and conversions to primitive
types for compatibility with ``std::format`` and to prevent potential ODR
violations. Use ``format_as`` instead.
* Added support for fill, align and width to the time point formatter
* Implemented formatting of subseconds
* Added precision support to ``%S``
* Added support for ``std::utc_time``
* Switched formatting of ``std::chrono::system_clock`` from local time to UTC
for compatibility with the standard
* Added support for ``%Ez`` and ``%Oz`` to chrono formatters.
* Improved validation of format specifiers for ``std::chrono::duration``
* Fixed formatting of time points before the epoch
* Experimental: implemented glibc extension for padding seconds, minutes and
hours
* Added a formatter for ``std::exception``
* Moved ``std::error_code`` formatter from ``fmt/os.h`` to ``fmt/std.h``.
* Added formatters for standard container adapters: ``std::priority_queue``,
``std::queue`` and ``std::stack``
* Added a formatter for ``std::optional`` to ``fmt/std.h``.
* Fixed formatting of valueless by exception variants
* Made ``fmt::ptr`` accept ``unique_ptr`` with a custom deleter
* Fixed formatting of noncopyable ranges and nested ranges of chars
* Fixed issues with formatting of paths and ranges of paths
* Improved handling of invalid Unicode in paths.
* Enabled compile-time checks on Apple clang 14 and later
* Improved compile-time checks of named arguments
* Fixed formatting when both alignment and ``0`` are given
* Improved Unicode support in the experimental file API on Windows
* Unified UTF transcoding
* Added support for UTF-8 digit separators via an experimental locale facet
* Added an overload of ``formatted_size`` that takes a locale
* Removed the deprecated ``FMT_DEPRECATED_OSTREAM``.
* Fixed a UB when using a null ``std::string_view`` with ``fmt::to_string``
or format string compilation
* Added ``starts_with`` to the fallback ``string_view`` implementation
* Added ``fmt::basic_format_string::get()`` for compatibility with
``basic_format_string``
* Added ``println`` for compatibility with C++23
* Improved documentation
* Improved build configuration and tests
* Fixed a regression in handling empty format specifiers after a colon (``{:}``)
* Worked around a broken implementation of ``std::is_constant_evaluated`` in
some versions of libstdc++ on clang
* Fixed formatting of volatile variables
* Fixed various warnings and compilation issues

Log message:
fmtlib: update to 9.1.0
From Wongboo via Github pull request.
Closes NetBSD/pkgsrc#111.
9.1.0 - 2022-08-27
------------------
* ``fmt::formatted_size`` now works at compile time
. For example
(`godbolt <https://godbolt.org/z/1MW5rMdf8>`__):
.. code:: c++
#include <fmt/compile.h>
int main() {
using namespace fmt::literals;
constexpr size_t n = fmt::formatted_size("{}"_cf, 42);
fmt::print("{}\n", n); // prints 2
}
* Fixed handling of invalid UTF-8.
* Improved Unicode support in ``ostream`` overloads of ``print``.
* Fixed handling of the sign specifier in localized formatting on systems with
32-bit ``wchar_t`` .
* Added support for wide streams to ``fmt::streamed``.
* Added the ``n`` specifier that disables the output of delimiters when
formatting ranges.
For example (`godbolt <https://godbolt.org/z/roKqGdj8c>`__):
.. code:: c++
#include <fmt/ranges.h>
#include <vector>
int main() {
auto v = std::vector{1, 2, 3};
fmt::print("{:n}\n", v); // prints 1, 2, 3
}
* Worked around problematic ``std::string_view`` constructors introduced in
C++23
* Improve handling (exclusion) of recursive ranges
* Improved error reporting in format string compilation.
* Improved the implementation of
`Dragonbox <https://github.com/jk-jeon/dragonbox>`_, the algorithm used for
the default floating-point formatting.
* Fixed issues with floating-point formatting on exotic platforms.
* Improved the implementation of chrono formatting.
* Improved documentation.
* Improved build configuration.
* Fixed various warnings and compilation issues.
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 <https://godbolt.org/z/G37PTeG3b>`__):
.. code:: c++
#include <array>
#include <fmt/compile.h>
consteval auto compile_time_dtoa(double value) -> std::array<char, \
10> {
auto result = std::array<char, 10>();
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 <https://github.com/jk-jeon/dragonbox>`_, the algorithm used for
the default floating-point formatting.
* 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 <https://godbolt.org/z/5sEc5qMsf>`__):
.. code:: c++
#include <fmt/ostream.h>
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<date> : 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 <https://godbolt.org/z/5G3346G1f>`__):
.. code:: c++
#include <thread>
#include <fmt/ostream.h>
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.
For example (`godbolt <https://godbolt.org/z/KG9z6cq68>`__):
.. code:: c++
#include <variant>
#include <fmt/std.h>
int main() {
auto v = std::variant<int, std::string>(42);
fmt::print("{}\n", v);
}
prints::
variant(42)
Thanks `@jehelset <https://github.com/jehelset>`_.
* Added experimental ``std::filesystem::path`` formatting support
(`#2865 <https://github.com/fmtlib/fmt/issues/2865>`_,
`#2902 <https://github.com/fmtlib/fmt/pull/2902>`_,
`#2917 <https://github.com/fmtlib/fmt/issues/2917>`_,
`#2918 <https://github.com/fmtlib/fmt/pull/2918>`_).
For example (`godbolt <https://godbolt.org/z/o44dMexEb>`__):
.. code:: c++
#include <filesystem>
#include <fmt/std.h>
int main() {
fmt::print("There is no place like {}.", \
std::filesystem::path("/home"));
}
prints::
There is no place like "/home".
* Added a ``std::thread::id`` formatter to ``fmt/std.h``.
For example (`godbolt <https://godbolt.org/z/j1azbYf3E>`__):
.. code:: c++
#include <thread>
#include <fmt/std.h>
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.
.
For example (`godbolt <https://godbolt.org/z/vWGW7v5M6>`__):
.. code:: c++
#include <fmt/chrono.h>
#include <fmt/color.h>
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");
}
* Made ``fmt::print`` overload for text styles correctly handle UTF-8.
* Fixed Unicode handling when writing to an ostream.
* Added support for nested specifiers to range formatting:
.. code:: c++
#include <vector>
#include <fmt/ranges.h>
int main() {
fmt::print("{::#x}\n", std::vector{10, 20, 30});
}
prints ``[0xa, 0x14, 0x1e]``.
* Implemented escaping of wide strings in ranges.
* Added support for ranges with ``begin`` / ``end`` found via the
argument-dependent lookup.
* Fixed formatting of certain kinds of ranges of ranges.
* Fixed handling of maps with element types other than ``std::pair``.
* Made tuple formatter enabled only if elements are formattable.
* Made ``fmt::join`` compatible with format string compilation.
* Made compile-time checks work with named arguments of custom types and
``std::ostream`` ``print`` overloads.
* Removed ``make_args_checked`` because it is no longer needed for compile-time.
* 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``.
* Removed a redundant buffer resize when formatting to ``std::ostream``.
* Made precision computation for strings consistent with width.
.
* Fixed handling of locale separators in floating point formatting.
* Made sign specifiers work with ``__int128_t``.
* Improved support for systems such as CHERI with extra data stored in pointers.
* Improved documentation.
* Improved build configuration.
* Fixed various warnings and compilation issues.

* Fixed chorno formatting on big endian systems
* Fixed a linkage error with mingw
8.1.0 - 2022-01-02
------------------
* Optimized chrono formatting
Processing of some specifiers such as ``%z`` and ``%Y`` is now up to 10-20
times faster, for example on GCC 11 with libstdc++::
----------------------------------------------------------------------------
Benchmark Before After
----------------------------------------------------------------------------
FMTFormatter_z 261 ns 26.3 ns
FMTFormatterCompile_z 246 ns 11.6 ns
FMTFormatter_Y 263 ns 26.1 ns
FMTFormatterCompile_Y 244 ns 10.5 ns
----------------------------------------------------------------------------

int main() {
fmt::print("{:%S}", std::chrono::milliseconds(1234));
}
prints "01.234".
* Fixed handling of precision 0 when formatting chrono durations
* Fixed an overflow on invalid inputs in the ``tm`` formatter
* Added ``fmt::group_digits`` that formats integers with a non-localized digit
separator (comma) for groups of three digits.
For example (`godbolt <https://godbolt.org/z/TxGxG9Poq>`__):
.. code:: c++
#include <fmt/format.h>
int main() {
fmt::print("{} dollars", fmt::group_digits(1000000));

using namespace fmt::literals;
fmt::print("{answer:s}", "answer"_a=42);
}
gives a compile-time error on compilers with C++20 ``consteval`` and non-type
template parameter support (gcc 10+) because ``s`` is not a valid format
specifier for an integer.
* Implemented escaping of string range elements.
For example (`godbolt <https://godbolt.org/z/rKvM1vKf3>`__):
.. code:: c++
#include <fmt/ranges.h>

fmt::print("{}", std::vector<std::string>{"\naan"});
}
is now printed as::
["\naan"]
instead of::
["
aan"]
* Switched to JSON-like representation of maps and sets for consistency with
Python's ``str.format``.
For example (`godbolt <https://godbolt.org/z/seKjoY9W5>`__):
.. code:: c++
#include <fmt/ranges.h>
#include <map>
int main() {
fmt::print("{}", std::map<std::string, \
int>{{"answer", 42}});
}
is now printed as::
{"answer": 42}
