|
||
Processing of some specifiers such as ``%z`` and ``%Y`` is now up to 10-20
|
||
times faster, for example on GCC 11 with libstdc++::

Thanks `@phprus (Vladislav Shchapov) <https://github.com/phprus>`_ and
|
||
`@toughengineer (Pavel Novikov) <https://github.com/toughengineer>`_.
|
||
|
||
* Implemented subsecond formatting for chrono durations
|
||
(`#2623 <https://github.com/fmtlib/fmt/pull/2623>`_).
|
||
For example (`godbolt <https://godbolt.org/z/es7vWTETe>`__):
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/chrono.h>
|
||
|
||
int main() {
|
||
fmt::print("{:%S}", std::chrono::milliseconds(1234));
|
||
}
|
||
|
||
prints "01.234".
|
||
|
||
Thanks `@matrackif <https://github.com/matrackif>`_.
|
||
|
||
* Fixed handling of precision 0 when formatting chrono durations
|
||
(`#2587 <https://github.com/fmtlib/fmt/issues/2587>`_,
|
||
`#2588 <https://github.com/fmtlib/fmt/pull/2588>`_).
|
||
Thanks `@lukester1975 <https://github.com/lukester1975>`_.
|
||
|
||
* Fixed an overflow on invalid inputs in the ``tm`` formatter
|
||
(`#2564 <https://github.com/fmtlib/fmt/pull/2564>`_).
|
||
Thanks `@phprus (Vladislav Shchapov) <https://github.com/phprus>`_.
|
||
|
||
* 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));
|
||
}
|
||
|
||
prints "1,000,000 dollars".
|
||
|
||
* Added support for faint, conceal, reverse and blink text styles
|
||
(`#2394 <https://github.com/fmtlib/fmt/pull/2394>`_):
|
||
|
||
https://user-images.githubusercontent.com/576385/147710227-c68f5317-f8fa-42c3-9123-7c4ba3c398cb.mp4
|
||
|
||
Thanks `@benit8 (Benoît Lormeau) <https://github.com/benit8>`_ and
|
||
`@data-man (Dmitry Atamanov) <https://github.com/data-man>`_.
|
||
|
||
* Added experimental support for compile-time floating point formatting
|
||
(`#2426 <https://github.com/fmtlib/fmt/pull/2426>`_,
|
||
`#2470 <https://github.com/fmtlib/fmt/pull/2470>`_).
|
||
It is currently limited to the header-only mode.
|
||
Thanks `@alexezeder (Alexey Ochapov) <https://github.com/alexezeder>`_.
|
||
|
||
* Added UDL-based named argument support to compile-time format string checks
|
||
(`#2640 <https://github.com/fmtlib/fmt/issues/2640>`_,
|
||
`#2649 <https://github.com/fmtlib/fmt/pull/2649>`_).
|
||
For example (`godbolt <https://godbolt.org/z/ohGbbvonv>`__):
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/format.h>
|
||
|
||
int main() {
|
||
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.
|
||
|
||
Thanks `@alexezeder (Alexey Ochapov) <https://github.com/alexezeder>`_.
|
||
|
||
* Implemented escaping of string range elements.
|
||
For example (`godbolt <https://godbolt.org/z/rKvM1vKf3>`__):
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/ranges.h>
|
||
#include <vector>
|
||
|
||
int main() {
|
||
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}
|
||
|
||
* Extended ``fmt::join`` to support C++20-only ranges
|
||
(`#2549 <https://github.com/fmtlib/fmt/pull/2549>`_).
|
||
Thanks `@BRevzin (Barry Revzin) <https://github.com/BRevzin>`_.
|
||
|
||
* Optimized handling of non-const-iterable ranges and implemented initial
|
||
support for non-const-formattable types.
|
||
|
||
* Disabled implicit conversions of scoped enums to integers that was
|
||
accidentally introduced in earlier versions
|
||
(`#1841 <https://github.com/fmtlib/fmt/pull/1841>`_).
|
||
|
||
* Deprecated implicit conversion of ``[const] signed char*`` and
|
||
``[const] unsigned char*`` to C strings.
|
||
|
||
* Deprecated ``_format``, a legacy UDL-based format API
|
||
(`#2646 <https://github.com/fmtlib/fmt/pull/2646>`_).
|
||
Thanks `@alexezeder (Alexey Ochapov) <https://github.com/alexezeder>`_.
|
||
|
||
* Marked ``format``, ``formatted_size`` and ``to_string`` as ``[[nodiscard]]``
|
||
(`#2612 <https://github.com/fmtlib/fmt/pull/2612>`_).
|
||
`@0x8000-0000 (Florin Iucha) <https://github.com/0x8000-0000>`_.
|
||
|
||
* Added missing diagnostic when trying to format function and member pointers
|
||
as well as objects convertible to pointers which is explicitly disallowed
|
||

8.0.0 - 2021-06-21
|
||
------------------
|
||
|
||
* Enabled compile-time format string checks by default.
|
||
For example (`godbolt <https://godbolt.org/z/sMxcohGjz>`__):
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/core.h>
|
||
|
||
int main() {
|
||
fmt::print("{:d}", "I am not a number");
|
||
}
|
||
|
||
gives a compile-time error on compilers with C++20 ``consteval`` support
|
||
(gcc 10+, clang 11+) because ``d`` is not a valid format specifier for a
|
||
string.
|
||
|
||
To pass a runtime string wrap it in ``fmt::runtime``:
|
||
|
||
.. code:: c++
|
||
|
||
fmt::print(fmt::runtime("{:d}"), "I am not a number");
|
||
|
||
* Added compile-time formatting

`#2129 <https://github.com/fmtlib/fmt/pull/2129>`_,
|
||
`#2326 <https://github.com/fmtlib/fmt/pull/2326>`_).
|
||
For example (`godbolt <https://godbolt.org/z/Mxx9d89jM>`__):
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/compile.h>
|
||
|
||
consteval auto compile_time_itoa(int 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_itoa(42);
|
||
|
||
Most of the formatting functionality is available at compile time with a
|
||
notable exception of floating-point numbers and pointers.
|
||
Thanks `@alexezeder (Alexey Ochapov) <https://github.com/alexezeder>`_.
|
||
|
||
* Optimized handling of format specifiers during format string compilation.
|
||
For example, hexadecimal formatting (``"{:x}"``) is now 3-7x faster than
|
||
before when using ``format_to`` with format string compilation and a
|
||
stack-allocated buffer (`#1944 <https://github.com/fmtlib/fmt/issues/1944>`_).

||

|
||
|
||
In other cases, especially involving ``std::string`` construction, the
|
||
speed up is usually lower because handling format specifiers takes a smaller
|
||
fraction of the total time.
|
||
|
||
* Added the ``_cf`` user-defined literal to represent a compiled format string.
|
||
It can be used instead of the ``FMT_COMPILE`` macro
|
||
(`#2043 <https://github.com/fmtlib/fmt/pull/2043>`_,
|
||
`#2242 <https://github.com/fmtlib/fmt/pull/2242>`_):
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/compile.h>
|
||
|
||
using namespace fmt::literals;
|
||
auto s = fmt::format(FMT_COMPILE("{}"), 42); // 🙁 not modern
|
||
auto s = fmt::format("{}"_cf, 42); // 🙂 modern as hell
|
||
|
||
It requires compiler support for class types in non-type template parameters
|
||
(a C++20 feature) which is available in GCC 9.3+.
|
||
Thanks `@alexezeder (Alexey Ochapov) <https://github.com/alexezeder>`_.
|
||
|
||
* Format string compilation now requires ``format`` functions of ``formatter``
|
||
specializations for user-defined types to be ``const``:
|
||
|
||
.. code:: c++
|
||
|
||
template <> struct fmt::formatter<my_type>: formatter<string_view> {
|
||
template <typename FormatContext>
|
||
auto format(my_type obj, FormatContext& ctx) const { // Note const here.
|
||
// ...
|
||
}
|
||
};
|
||
|
||
* Added UDL-based named argument support to format string compilation
|
||
(`#2243 <https://github.com/fmtlib/fmt/pull/2243>`_,
|
||
`#2281 <https://github.com/fmtlib/fmt/pull/2281>`_). For example:
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/compile.h>
|
||
|
||
using namespace fmt::literals;
|
||
auto s = fmt::format(FMT_COMPILE("{answer}"), "answer"_a = 42);
|
||
|
||
Here the argument named "answer" is resolved at compile time with no
|
||
runtime overhead.
|
||
Thanks `@alexezeder (Alexey Ochapov) <https://github.com/alexezeder>`_.
|
||
|
||
* Added format string compilation support to ``fmt::print``
|
||
(`#2280 <https://github.com/fmtlib/fmt/issues/2280>`_,
|
||
`#2304 <https://github.com/fmtlib/fmt/pull/2304>`_).
|
||
Thanks `@alexezeder (Alexey Ochapov) <https://github.com/alexezeder>`_.
|
||
|
||
* Added initial support for compiling {fmt} as a C++20 module
|
||
(`#2235 <https://github.com/fmtlib/fmt/pull/2235>`_,
|
||
`#2240 <https://github.com/fmtlib/fmt/pull/2240>`_,

||
`#2332 <https://github.com/fmtlib/fmt/pull/2332>`_,
|
||
`#2340 <https://github.com/fmtlib/fmt/pull/2340>`_).
|
||
Thanks `@DanielaE (Daniela Engert) <https://github.com/DanielaE>`_.
|
||
|
||
* Made symbols private by default reducing shared library size
|
||
(`#2301 <https://github.com/fmtlib/fmt/pull/2301>`_). For example there was
|
||
a ~15% reported reduction on one platform.
|
||
Thanks `@sergiud (Sergiu Deitsch) <https://github.com/sergiud>`_.
|
||
|
||
* Optimized includes making the result of preprocessing ``fmt/format.h``
|
||
~20% smaller with libstdc++/C++20 and slightly improving build times
|
||
(`#1998 <https://github.com/fmtlib/fmt/issues/1998>`_).
|
||
|
||
* Added support of ranges with non-const ``begin`` / ``end``
|
||
(`#1953 <https://github.com/fmtlib/fmt/pull/1953>`_).
|
||
Thanks `@kitegi (sarah) <https://github.com/kitegi>`_.
|
||
|
||
* Added support of ``std::byte`` and other formattable types to ``fmt::join``
|
||
(`#1981 <https://github.com/fmtlib/fmt/issues/1981>`_,
|
||
`#2040 <https://github.com/fmtlib/fmt/issues/2040>`_,
|
||
`#2050 <https://github.com/fmtlib/fmt/pull/2050>`_,
|
||
`#2262 <https://github.com/fmtlib/fmt/issues/2262>`_). For example:
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/format.h>
|
||
#include <cstddef>
|
||
#include <vector>
|
||
|
||
int main() {
|
||
auto bytes = std::vector{std::byte(4), std::byte(2)};
|
||
fmt::print("{}", fmt::join(bytes, ""));
|
||
}
|
||
|
||
prints "42".
|
||
|
||
Thanks `@kamibo (Camille Bordignon) <https://github.com/kamibo>`_.
|
||
|
||
* Implemented the default format for ``std::chrono::system_clock``
|
||
(`#2319 <https://github.com/fmtlib/fmt/issues/2319>`_,
|
||
`#2345 <https://github.com/fmtlib/fmt/pull/2345>`_). For example:
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/chrono.h>
|
||
|
||
int main() {
|
||
fmt::print("{}", std::chrono::system_clock::now());
|
||
}
|
||
|
||
prints "2021-06-18 15:22:00" (the output depends on the current date and
|
||
time). Thanks `@sunmy2019 <https://github.com/sunmy2019>`_.
|
||
|
||
* Made more chrono specifiers locale independent by default. Use the ``'L'``
|
||
specifier to get localized formatting. For example:
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/chrono.h>
|
||
|
||
int main() {
|
||
std::locale::global(std::locale("ru_RU.UTF-8"));
|
||
auto monday = std::chrono::weekday(1);
|
||
fmt::print("{}\n", monday); // prints "Mon"
|
||
fmt::print("{:L}\n", monday); // prints "пн"
|
||
}
|
||
|
||
* Improved locale handling in chrono formatting
|
||
(`#2337 <https://github.com/fmtlib/fmt/issues/2337>`_,
|
||
`#2349 <https://github.com/fmtlib/fmt/pull/2349>`_,
|
||
`#2350 <https://github.com/fmtlib/fmt/pull/2350>`_).
|
||
Thanks `@phprus (Vladislav Shchapov) <https://github.com/phprus>`_.
|
||
|
||
* Deprecated ``fmt/locale.h`` moving the formatting functions that take a
|
||
locale to ``fmt/format.h`` (``char``) and ``fmt/xchar`` (other overloads).
|
||
This doesn't introduce a dependency on ``<locale>`` so there is virtually no
|
||
compile time effect.
|
||
|
||
* Deprecated an undocumented ``format_to`` overload that takes
|
||
``basic_memory_buffer``.
|
||
|
||
* Made parameter order in ``vformat_to`` consistent with ``format_to``
|
||
(`#2327 <https://github.com/fmtlib/fmt/issues/2327>`_).
|
||
|
||
* Added support for time points with arbitrary durations
|
||
(`#2208 <https://github.com/fmtlib/fmt/issues/2208>`_). For example:
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/chrono.h>
|
||
|
||
int main() {
|
||
using tp = std::chrono::time_point<
|
||
std::chrono::system_clock, std::chrono::seconds>;
|
||
fmt::print("{:%S}", tp(std::chrono::seconds(42)));
|
||
}
|
||
|
||
prints "42".
|
||
|
||
* Formatting floating-point numbers no longer produces trailing zeros by default
|
||
for consistency with ``std::format``. For example:
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/core.h>
|
||
|
||
int main() {
|
||
fmt::print("{0:.3}", 1.1);
|
||
}
|
||
|
||
prints "1.1". Use the ``'#'`` specifier to keep trailing zeros.
|
||
|
||
* Dropped a limit on the number of elements in a range and replaced ``{}`` with
|
||
``[]`` as range delimiters for consistency with Python's ``str.format``.
|
||
|
||
* The ``'L'`` specifier for locale-specific numeric formatting can now be
|
||
combined with presentation specifiers as in ``std::format``. For example:
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/core.h>
|
||
#include <locale>
|
||
|
||
int main() {
|
||
std::locale::global(std::locale("fr_FR.UTF-8"));
|
||
fmt::print("{0:.2Lf}", 0.42);
|
||
}
|
||
|
||
prints "0,42". The deprecated ``'n'`` specifier has been removed.
|
||
|
||
* Made the ``0`` specifier ignored for infinity and NaN
|
||
(`#2305 <https://github.com/fmtlib/fmt/issues/2305>`_,
|
||
`#2310 <https://github.com/fmtlib/fmt/pull/2310>`_).
|
||
Thanks `@Liedtke (Matthias Liedtke) <https://github.com/Liedtke>`_.
|
||
|
||
* Made the hexfloat formatting use the right alignment by default
|
||
(`#2308 <https://github.com/fmtlib/fmt/issues/2308>`_,
|
||
`#2317 <https://github.com/fmtlib/fmt/pull/2317>`_).
|
||
Thanks `@Liedtke (Matthias Liedtke) <https://github.com/Liedtke>`_.
|
||
|
||
* Removed the deprecated numeric alignment (``'='``). Use the ``'0'`` specifier
|
||
instead.
|
||
|
||
* Removed the deprecated ``fmt/posix.h`` header that has been replaced with
|
||
``fmt/os.h``.
|
||
|
||
* Removed the deprecated ``format_to_n_context``, ``format_to_n_args`` and
|
||
``make_format_to_n_args``. They have been replaced with ``format_context``,
|
||
``format_args` and ``make_format_args`` respectively.
|
||
|
||
* Moved ``wchar_t``-specific functions and types to ``fmt/xchar.h``.
|
||
You can define ``FMT_DEPRECATED_INCLUDE_XCHAR`` to automatically include
|
||
``fmt/xchar.h`` from ``fmt/format.h`` but this will be disabled in the next
|
||
major release.
|
||
|
||
* Fixed handling of the ``'+'`` specifier in localized formatting
|
||
(`#2133 <https://github.com/fmtlib/fmt/issues/2133>`_).
|
||
|
||
* Added support for the ``'s'`` format specifier that gives textual
|
||
representation of ``bool``
|
||
(`#2094 <https://github.com/fmtlib/fmt/issues/2094>`_,
|
||
`#2109 <https://github.com/fmtlib/fmt/pull/2109>`_). For example:
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/core.h>
|
||
|
||
int main() {
|
||
fmt::print("{:s}", true);
|
||
}
|
||
|
||
prints "true".
|
||
Thanks `@powercoderlol (Ivan Polyakov) <https://github.com/powercoderlol>`_.
|
||
|
||
* Made ``fmt::ptr`` work with function pointers
|
||
(`#2131 <https://github.com/fmtlib/fmt/pull/2131>`_). For example:
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/format.h>
|
||
|
||
int main() {
|
||
fmt::print("My main: {}\n", fmt::ptr(main));
|
||
}
|
||
|
||
Thanks `@mikecrowe (Mike Crowe) <https://github.com/mikecrowe>`_.
|
||
|
||
* The undocumented support for specializing ``formatter`` for pointer types
|
||
has been removed.
|
||
|
||
* Fixed ``fmt::formatted_size`` with format string compilation
|
||
(`#2141 <https://github.com/fmtlib/fmt/pull/2141>`_,
|
||
`#2161 <https://github.com/fmtlib/fmt/pull/2161>`_).
|
||
Thanks `@alexezeder (Alexey Ochapov) <https://github.com/alexezeder>`_.
|
||
|
||
* Fixed handling of empty format strings during format string compilation
|
||
(`#2042 <https://github.com/fmtlib/fmt/issues/2042>`_):
|
||
|
||
.. code:: c++
|
||
|
||
auto s = fmt::format(FMT_COMPILE(""));
|
||
|
||
Thanks `@alexezeder (Alexey Ochapov) <https://github.com/alexezeder>`_.
|
||
|
||
* Fixed handling of enums in ``fmt::to_string``
|
||
(`#2036 <https://github.com/fmtlib/fmt/issues/2036>`_).
|
||
|
||
* Improved width computation
|
||
(`#2033 <https://github.com/fmtlib/fmt/issues/2033>`_,
|
||
`#2091 <https://github.com/fmtlib/fmt/issues/2091>`_). For example:
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/core.h>
|
||
|
||
int main() {
|
||
fmt::print("{:-<10}{}\n", "你好", "世界");
|
||
fmt::print("{:-<10}{}\n", "hello", "world");
|
||
}
|
||
|
||
prints

119840373-cea3ca80-beb9-11eb-91e0-54266c48e181.png
|
||
|
||
on a modern terminal.
|
||
|
||
* The experimental fast output stream (``fmt::ostream``) is now truncated by
|
||
default for consistency with ``fopen``
|
||
(`#2018 <https://github.com/fmtlib/fmt/issues/2018>`_). For example:
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/os.h>
|
||
|
||
int main() {
|
||
fmt::ostream out1 = fmt::output_file("guide");
|
||
out1.print("Zaphod");
|
||
out1.close();
|
||
fmt::ostream out2 = fmt::output_file("guide");
|
||
out2.print("Ford");
|
||
}
|
||
|
||
writes "Ford" to the file "guide". To preserve the old file content if any
|
||
pass ``fmt::file::WRONLY | fmt::file::CREATE`` flags to ``fmt::output_file``.
|
||
|
||
* Fixed moving of ``fmt::ostream`` that holds buffered data
|
||
(`#2197 <https://github.com/fmtlib/fmt/issues/2197>`_,
|
||
`#2198 <https://github.com/fmtlib/fmt/pull/2198>`_).
|
||
Thanks `@vtta <https://github.com/vtta>`_.
|
||
|
||
* Replaced the ``fmt::system_error`` exception with a function of the same
|
||
name that constructs ``std::system_error``
|
||
(`#2266 <https://github.com/fmtlib/fmt/issues/2266>`_).
|
||
|
||
* Replaced the ``fmt::windows_error`` exception with a function of the same
|
||
name that constructs ``std::system_error`` with the category returned by
|
||
``fmt::system_category()``
|
||
(`#2274 <https://github.com/fmtlib/fmt/issues/2274>`_,
|
||
`#2275 <https://github.com/fmtlib/fmt/pull/2275>`_).
|
||
The latter is similar to ``std::sytem_category`` but correctly handles UTF-8.
|
||
Thanks `@phprus (Vladislav Shchapov) <https://github.com/phprus>`_.
|
||
|
||
* Replaced ``fmt::error_code`` with ``std::error_code`` and made it formattable
|
||
(`#2269 <https://github.com/fmtlib/fmt/issues/2269>`_,
|
||
`#2270 <https://github.com/fmtlib/fmt/pull/2270>`_,
|
||
`#2273 <https://github.com/fmtlib/fmt/pull/2273>`_).
|
||
Thanks `@phprus (Vladislav Shchapov) <https://github.com/phprus>`_.
|
||
|
||
* Added speech synthesis support
|
||
(`#2206 <https://github.com/fmtlib/fmt/pull/2206>`_).
|
||
|
||
* Made ``format_to`` work with a memory buffer that has a custom allocator
|
||
(`#2300 <https://github.com/fmtlib/fmt/pull/2300>`_).
|
||
Thanks `@voxmea <https://github.com/voxmea>`_.
|
||
|
||
* Added ``Allocator::max_size`` support to ``basic_memory_buffer``.
|
||
(`#1960 <https://github.com/fmtlib/fmt/pull/1960>`_).
|
||
Thanks `@phprus (Vladislav Shchapov) <https://github.com/phprus>`_.
|
||
|
||
* Added wide string support to ``fmt::join``
|
||
(`#2236 <https://github.com/fmtlib/fmt/pull/2236>`_).
|
||
Thanks `@crbrz <https://github.com/crbrz>`_.
|
||
|
||
* Made iterators passed to ``formatter`` specializations via a format context
|
||
satisfy C++20 ``std::output_iterator`` requirements
|
||
(`#2156 <https://github.com/fmtlib/fmt/issues/2156>`_,
|
||
`#2158 <https://github.com/fmtlib/fmt/pull/2158>`_,
|
||
`#2195 <https://github.com/fmtlib/fmt/issues/2195>`_,

`#2204 <https://github.com/fmtlib/fmt/pull/2204>`_).
|
||
Thanks `@randomnetcat (Jason Cobb) <https://github.com/randomnetcat>`_.
|
||
|
||
* Optimized the ``printf`` implementation

7.1.3 - 2020-11-24
|
||
------------------
|
||
|
||
* Fixed handling of buffer boundaries in ``format_to_n``
|
||
(`#1996 <https://github.com/fmtlib/fmt/issues/1996>`_,
|
||
`#2029 <https://github.com/fmtlib/fmt/issues/2029>`_).
|
||
|
||
* Fixed linkage errors when linking with a shared library
|
||
(`#2011 <https://github.com/fmtlib/fmt/issues/2011>`_).
|
||
|
||
* Reintroduced ostream support to range formatters
|
||
(`#2014 <https://github.com/fmtlib/fmt/issues/2014>`_).
|
||
|
||
* Worked around an issue with mixing std versions in gcc
|
||
(`#2017 <https://github.com/fmtlib/fmt/issues/2017>`_).
|
||
|
||
7.1.2 - 2020-11-04
|
||
------------------
|
||
|
||
* Fixed floating point formatting with large precision
|
||
(`#1976 <https://github.com/fmtlib/fmt/issues/1976>`_).
|
||
|
||
7.1.1 - 2020-11-01
|
||
------------------
|
||
|
||
* Fixed ABI compatibility with 7.0.x
|
||
(`#1961 <https://github.com/fmtlib/fmt/issues/1961>`_).
|
||
|
||
* Added the ``FMT_ARM_ABI_COMPATIBILITY`` macro to work around ABI
|
||
incompatibility between GCC and Clang on ARM
|
||
(`#1919 <https://github.com/fmtlib/fmt/issues/1919>`_).
|
||
|
||
* Worked around a SFINAE bug in GCC 8
|
||
(`#1957 <https://github.com/fmtlib/fmt/issues/1957>`_).
|
||
|
||
* Fixed linkage errors when building with GCC's LTO
|
||
(`#1955 <https://github.com/fmtlib/fmt/issues/1955>`_).
|
||
|
||
* Fixed a compilation error when building without ``__builtin_clz`` or equivalent
|
||
(`#1968 <https://github.com/fmtlib/fmt/pull/1968>`_).
|
||
Thanks `@tohammer (Tobias Hammer) <https://github.com/tohammer>`_.
|
||
|
||
* Fixed a sign conversion warning
|
||
(`#1964 <https://github.com/fmtlib/fmt/pull/1964>`_).
|
||
Thanks `@OptoCloud <https://github.com/OptoCloud>`_.
|
||
|
||
7.1.0 - 2020-10-25
|
||
------------------
|
||
|
||
* Switched from `Grisu3
|
||
<https://www.cs.tufts.edu/~nr/cs257/archive/florian-loitsch/printf.pdf>`_
|
||
to `Dragonbox <https://github.com/jk-jeon/dragonbox>`_ for the default
|
||
floating-point formatting which gives the shortest decimal representation
|
||
with round-trip guarantee and correct rounding
|
||
(`#1882 <https://github.com/fmtlib/fmt/pull/1882>`_,
|
||
`#1887 <https://github.com/fmtlib/fmt/pull/1887>`_,
|
||
`#1894 <https://github.com/fmtlib/fmt/pull/1894>`_). This makes {fmt} up to
|
||
20-30x faster than common implementations of ``std::ostringstream`` and
|
||
``sprintf`` on `dtoa-benchmark <https://github.com/fmtlib/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.
|
||
|
||
Thanks `@jk-jeon (Junekey Jeon) <https://github.com/jk-jeon>`_.
|
||
|
||
* Added an experimental unsynchronized file output API which, together with
|
||
`format string compilation <https://fmt.dev/latest/api.html#compile-api>`_,
|
||
can give `5-9 times speed up compared to fprintf
|
||
<https://www.zverovich.net/2020/08/04/optimal-file-buffer-size.html>`_
|
||
on common platforms (`godbolt <https://godbolt.org/z/nsTcG8>`__):
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/os.h>
|
||
|
||
int main() {
|
||
auto f = fmt::output_file("guide");
|
||
f.print("The answer is {}.", 42);
|
||
}
|
||
|
||
* Added a formatter for ``std::chrono::time_point<system_clock>``
|
||
(`#1819 <https://github.com/fmtlib/fmt/issues/1819>`_,
|
||
`#1837 <https://github.com/fmtlib/fmt/pull/1837>`_). For example
|
||
(`godbolt <https://godbolt.org/z/c4M6fh>`__):
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/chrono.h>
|
||
|
||
int main() {
|
||
auto now = std::chrono::system_clock::now();
|
||
fmt::print("The time is {:%H:%M:%S}.\n", now);
|
||
}
|
||
|
||
Thanks `@adamburgess (Adam Burgess) <https://github.com/adamburgess>`_.
|
||
|
||
* Added support for ranges with non-const ``begin``/``end`` to ``fmt::join``

(`#1784 <https://github.com/fmtlib/fmt/issues/1784>`_,
|
||
`#1786 <https://github.com/fmtlib/fmt/pull/1786>`_). For example
|
||
(`godbolt <https://godbolt.org/z/jP63Tv>`__):
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/ranges.h>

#include <range/v3/view/filter.hpp>
|

int main() {

fmt::print("{}\n", fmt::join(range, ""));

prints "accc".
|
||
|
||
Thanks `@tonyelewis (Tony E Lewis) <https://github.com/tonyelewis>`_.
|
||
|
||
* Added a ``memory_buffer::append`` overload that takes a range
|
||
(`#1806 <https://github.com/fmtlib/fmt/pull/1806>`_).
|
||
Thanks `@BRevzin (Barry Revzin) <https://github.com/BRevzin>`_.
|
||
|
||
* Improved handling of single code units in ``FMT_COMPILE``. For example:
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/compile.h>
|
||
|
||
char* f(char* buf) {
|
||
return fmt::format_to(buf, FMT_COMPILE("x{}"), 42);
|
||
}
|
||
|
||
compiles to just (`godbolt <https://godbolt.org/z/5vncz3>`__):
|
||
|
||
.. code:: asm
|
||
|
||
_Z1fPc:
|
||
movb $120, (%rdi)
|
||
xorl %edx, %edx
|
||
cmpl $42, _ZN3fmt2v76detail10basic_dataIvE23zero_or_powers_of_10_32E+8(%rip)
|
||
movl $3, %eax
|
||
seta %dl
|
||
subl %edx, %eax
|
||
movzwl _ZN3fmt2v76detail10basic_dataIvE6digitsE+84(%rip), %edx
|
||
cltq
|
||
addq %rdi, %rax
|
||
movw %dx, -2(%rax)
|
||
ret
|
||
|
||
Here a single ``mov`` instruction writes ``'x'`` (``$120``) to the output
|
||
buffer.
|
||
|
||
* Added dynamic width support to format string compilation
|
||
(`#1809 <https://github.com/fmtlib/fmt/issues/1809>`_).
|
||
|
||
* Improved error reporting for unformattable types: now you'll get the type name
|
||
directly in the error message instead of the note:
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/core.h>
|
||
|
||
struct how_about_no {};
|
||
|
||
int main() {
|
||
fmt::print("{}", how_about_no());
|
||
}
|
||
|
||
Error (`godbolt <https://godbolt.org/z/GoxM4e>`__):
|
||
|
||
``fmt/core.h:1438:3: error: static_assert failed due to requirement
|
||

|
||
To make type T formattable provide a formatter<T> specialization:
|
||
https://fmt.dev/latest/api.html#udt"
|
||
...``
|
||
|
||
* Added the `make_args_checked <https://fmt.dev/7.1.0/api.html#argument-lists>`_
|
||
function template that allows you to write formatting functions with
|
||
compile-time format string checks and avoid binary code bloat
|
||
(`godbolt <https://godbolt.org/z/PEf9qr>`__):
|
||
|
||
.. code:: c++

void vlog(const char* file, int line, fmt::string_view format,
|
||
fmt::format_args args) {

log(__FILE__, __LINE__, FMT_STRING(format), __VA_ARGS__)

MY_LOG("invalid squishiness: {}", 42);
|
||
|
||
* Replaced ``snprintf`` fallback with a faster internal IEEE 754 ``float`` and
|
||
``double`` formatter for arbitrary precision. For example
|
||
(`godbolt <https://godbolt.org/z/dPhWvj>`__):
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/core.h>
|
||
|
||
int main() {
|
||
fmt::print("{:.500}\n", 4.9406564584124654E-324);
|
||
}
|
||
|
||
prints
|
||
|
||
``4.9406564584124654417656879286822137236505980261432476442558568250067550727020875186529983636163599237979656469544571773092665671035593979639877479601078187812630071319031140452784581716784898210368871863605699873072305000638740915356498438731247339727316961514003171538539807412623856559117102665855668676818703956031062493194527159149245532930545654440112748012970999954193198940908041656332452475714786901472678015935523861155013480352649347201937902681071074917033322268447533357208324319360923829e-324``.
|
||
|
||
* Made ``format_to_n`` and ``formatted_size`` part of the `core API
|
||
<https://fmt.dev/latest/api.html#core-api>`__
|
||
(`godbolt <https://godbolt.org/z/sPjY1K>`__):
|
||
|

||
#include <fmt/core.h>

||
int main() {
|
||
char buffer[10];
|
||
auto result = fmt::format_to_n(buffer, sizeof(buffer), "{}", 42);
|
||
}
|
||
|
||
* Added ``fmt::format_to_n`` overload with format string compilation
|
||
(`#1764 <https://github.com/fmtlib/fmt/issues/1764>`_,
|
||
`#1767 <https://github.com/fmtlib/fmt/pull/1767>`_,
|
||
`#1869 <https://github.com/fmtlib/fmt/pull/1869>`_). For example
|
||
(`godbolt <https://godbolt.org/z/93h86q>`__):
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/compile.h>
|
||
|
||
int main() {
|

fmt::format_to_n(buffer, sizeof(buffer), FMT_COMPILE("{}"), 42);

|
||
Thanks `@Kurkin (Dmitry Kurkin) <https://github.com/Kurkin>`_,
|
||
`@alexezeder (Alexey Ochapov) <https://github.com/alexezeder>`_.
|
||
|
||
* Added ``fmt::format_to`` overload that take ``text_style``
|
||
(`#1593 <https://github.com/fmtlib/fmt/issues/1593>`_,
|
||
`#1842 <https://github.com/fmtlib/fmt/issues/1842>`_,
|
||
`#1843 <https://github.com/fmtlib/fmt/pull/1843>`_). For example
|
||
(`godbolt <https://godbolt.org/z/91153r>`__):
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/color.h>
|
||
|
||
int main() {
|
||
std::string out;
|
||
fmt::format_to(std::back_inserter(out),
|
||
fmt::emphasis::bold | fg(fmt::color::red),
|
||
"The answer is {}.", 42);
|
||
}
|
||
|
||
Thanks `@Naios (Denis Blank) <https://github.com/Naios>`_.
|
||
|
||
* Made the ``'#'`` specifier emit trailing zeros in addition to the decimal
|
||
point (`#1797 <https://github.com/fmtlib/fmt/issues/1797>`_). For example
|
||
(`godbolt <https://godbolt.org/z/bhdcW9>`__):
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/core.h>
|
||
|
||
int main() {
|
||
fmt::print("{:#.2g}", 0.5);
|
||
}
|
||
|
||
prints ``0.50``.
|
||
|
||
* Changed the default floating point format to not include ``.0`` for
|
||
consistency with ``std::format`` and ``std::to_chars``
|
||
(`#1893 <https://github.com/fmtlib/fmt/issues/1893>`_,
|
||
`#1943 <https://github.com/fmtlib/fmt/issues/1943>`_). 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`` (`#1873 <https://github.com/fmtlib/fmt/issues/1873>`_,
|
||
`#1917 <https://github.com/fmtlib/fmt/issues/1917>`_).
|
||
|
||
* Made ``fmt::to_string`` fallback on ``ostream`` insertion operator if
|
||
the ``formatter`` specialization is not provided
|
||
(`#1815 <https://github.com/fmtlib/fmt/issues/1815>`_,
|
||
`#1829 <https://github.com/fmtlib/fmt/pull/1829>`_).
|
||
Thanks `@alexezeder (Alexey Ochapov) <https://github.com/alexezeder>`_.
|
||
|
||
* Added support for the append mode to the experimental file API and
|
||
improved ``fcntl.h`` detection.
|
||
(`#1847 <https://github.com/fmtlib/fmt/pull/1847>`_,
|
||
`#1848 <https://github.com/fmtlib/fmt/pull/1848>`_).
|
||
Thanks `@t-wiser <https://github.com/t-wiser>`_.
|
||
|
||
* Fixed handling of types that have both an implicit conversion operator and
|
||
an overloaded ``ostream`` insertion operator
|
||
(`#1766 <https://github.com/fmtlib/fmt/issues/1766>`_).
|
||
|
||
* Fixed a slicing issue in an internal iterator type
|
||
(`#1822 <https://github.com/fmtlib/fmt/pull/1822>`_).
|
||
Thanks `@BRevzin (Barry Revzin) <https://github.com/BRevzin>`_.
|
||
|
||
* Fixed an issue in locale-specific integer formatting
|
||
(`#1927 <https://github.com/fmtlib/fmt/issues/1927>`_).
|
||
|
||
* Fixed handling of exotic code unit types
|
||
(`#1870 <https://github.com/fmtlib/fmt/issues/1870>`_,
|
||
`#1932 <https://github.com/fmtlib/fmt/issues/1932>`_).
|
||
|
||
* Improved ``FMT_ALWAYS_INLINE``
|
||
(`#1878 <https://github.com/fmtlib/fmt/pull/1878>`_).
|
||
Thanks `@jk-jeon (Junekey Jeon) <https://github.com/jk-jeon>`_.
|
||
|
||
* Removed dependency on ``windows.h``
|
||
(`#1900 <https://github.com/fmtlib/fmt/pull/1900>`_).
|
||
Thanks `@bernd5 (Bernd Baumanns) <https://github.com/bernd5>`_.
|
||
|
||
* Optimized counting of decimal digits on MSVC
|
||
(`#1890 <https://github.com/fmtlib/fmt/pull/1890>`_).
|
||
Thanks `@mwinterb <https://github.com/mwinterb>`_.
|

|

|
||
* 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
|
||
(`#1778 <https://github.com/fmtlib/fmt/issues/1778>`_,

namespaces (`#1945 <https://github.com/fmtlib/fmt/pull/1945>`_).
|
||
Thanks `@darklukee <https://github.com/darklukee>`_.

||
(`#1782 <https://github.com/fmtlib/fmt/issues/1782>`_,
|
||
`#1801 <https://github.com/fmtlib/fmt/issues/1801>`_).
|
||
|
||
7.0.2 - 2020-07-29
|
||
------------------
|
||
|
||
* Worked around broken ``numeric_limits`` for 128-bit integers
|
||
(`#1725 <https://github.com/fmtlib/fmt/issues/1725>`_).

|
||
* Fixed minor issues with the documentation.
|
||
|
||
7.0.0 - 2020-07-05
|
||
------------------
|
||
|
||
* Reduced the library size. For example, on macOS a stripped test binary
|
||
statically linked with {fmt} `shrank from ~368k to less than 100k
|
||
<http://www.zverovich.net/2020/05/21/reducing-library-size.html>`_.
|
||
|
||
* Added a simpler and more efficient `format string compilation API
|
||
<https://fmt.dev/7.0.0/api.html#compile-api>`_:
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/compile.h>
|
||
|
||
// Converts 42 into std::string using the most efficient method and no
|
||
// runtime format string processing.
|
||
std::string s = fmt::format(FMT_COMPILE("{}"), 42);
|
||
|
||
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++
|
||
<http://www.zverovich.net/2020/06/13/fast-int-to-string-revisited.html>`_.
|
||
|
||
* Optimized handling of small format strings. For example,
|
||
|
||
.. code:: c++
|
||
|
||
fmt::format("Result: {}: ({},{},{},{})", str1, str2, str3, str4, str5)
|
||
|
||
is now ~40% faster (`#1685 <https://github.com/fmtlib/fmt/issues/1685>`_).
|
||
|
||
* Applied extern templates to improve compile times when using the core API
|
||
and ``fmt/format.h`` (`#1452 <https://github.com/fmtlib/fmt/issues/1452>`_).
|
||
For example, on macOS with clang the compile time of a test translation unit
|
||
dropped from 2.3s to 0.3s with ``-O2`` and from 0.6s to 0.3s with the default
|
||
settings (``-O0``).
|
||
|
||
Before (``-O2``)::
|
||
|
||
% time c++ -c test.cc -I include -std=c++17 -O2
|
||
c++ -c test.cc -I include -std=c++17 -O2 2.22s user 0.08s system 99% cpu 2.311 total
|
||
|
||
After (``-O2``)::
|
||
|
||
% time c++ -c test.cc -I include -std=c++17 -O2
|
||
c++ -c test.cc -I include -std=c++17 -O2 0.26s user 0.04s system 98% cpu 0.303 total
|
||
|
||
Before (default)::
|
||
|
||
% time c++ -c test.cc -I include -std=c++17
|
||
c++ -c test.cc -I include -std=c++17 0.53s user 0.06s system 98% cpu 0.601 total
|
||
|
||
After (default)::
|
||
|
||
% time c++ -c test.cc -I include -std=c++17
|
||
c++ -c test.cc -I include -std=c++17 0.24s user 0.06s system 98% cpu 0.301 total
|
||
|
||
It is still recommended to use ``fmt/core.h`` instead of ``fmt/format.h`` but
|
||
the compile time difference is now smaller. Thanks
|
||
`@alex3d <https://github.com/alex3d>`_ for the suggestion.
|
||
|
||
* Named arguments are now stored on stack (no dynamic memory allocations) and
|
||
the compiled code is more compact and efficient. For example
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/core.h>
|
||
|
||
int main() {
|
||
fmt::print("The answer is {answer}\n", fmt::arg("answer", 42));
|
||
}
|
||
|
||
compiles to just (`godbolt <https://godbolt.org/z/NcfEp_>`__)
|
||
|
||
.. code:: asm
|
||
|
||
.LC0:
|
||
.string "answer"
|
||
.LC1:
|
||
.string "The answer is {answer}\n"
|
||
main:
|
||
sub rsp, 56
|
||
mov edi, OFFSET FLAT:.LC1
|
||
mov esi, 23
|
||
movabs rdx, 4611686018427387905
|
||
lea rax, [rsp+32]
|
||
lea rcx, [rsp+16]
|
||
mov QWORD PTR [rsp+8], 1
|
||
mov QWORD PTR [rsp], rax
|
||
mov DWORD PTR [rsp+16], 42
|
||
mov QWORD PTR [rsp+32], OFFSET FLAT:.LC0
|
||
mov DWORD PTR [rsp+40], 0
|
||
call fmt::v6::vprint(fmt::v6::basic_string_view<char>,
|
||
fmt::v6::format_args)
|
||
xor eax, eax
|
||
add rsp, 56
|
||
ret
|
||
|
||
.L.str.1:
|
||
.asciz "answer"
|
||
|
||
* Implemented compile-time checks for dynamic width and precision
|
||
(`#1614 <https://github.com/fmtlib/fmt/issues/1614>`_):
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/format.h>
|
||
|
||
int main() {
|
||
fmt::print(FMT_STRING("{0:{1}}"), 42);
|
||
}
|
||
|
||
now gives a compilation error because argument 1 doesn't exist::
|
||
|
||
In file included from test.cc:1:
|
||
include/fmt/format.h:2726:27: error: constexpr variable 'invalid_format' must be
|
||
initialized by a constant expression
|
||
FMT_CONSTEXPR_DECL bool invalid_format =
|
||

|
||
...
|
||
include/fmt/core.h:569:26: note: in call to
|
||
'&checker(s, {}).context_->on_error(&"argument not found"[0])'
|
||
if (id >= num_args_) on_error("argument not found");
|
||
^
|
||
|
||
* Added sentinel support to ``fmt::join``
|
||
(`#1689 <https://github.com/fmtlib/fmt/pull/1689>`_)
|
||
|
||
.. code:: c++
|
||
|
||
struct zstring_sentinel {};
|
||
bool operator==(const char* p, zstring_sentinel) { return *p == '\0'; }
|
||
bool operator!=(const char* p, zstring_sentinel) { return *p != '\0'; }
|
||
|
||
struct zstring {
|
||
const char* p;
|
||
const char* begin() const { return p; }
|
||
zstring_sentinel end() const { return {}; }
|
||
};
|
||
|
||
auto s = fmt::format("{}", fmt::join(zstring{"hello"}, "_"));
|
||
// s == "h_e_l_l_o"
|
||
|
||
Thanks `@BRevzin (Barry Revzin) <https://github.com/BRevzin>`_.
|
||
|
||
* Added support for named arguments, ``clear`` and ``reserve`` to
|
||
``dynamic_format_arg_store``
|
||
(`#1655 <https://github.com/fmtlib/fmt/issues/1655>`_,
|
||
`#1663 <https://github.com/fmtlib/fmt/pull/1663>`_,
|
||
`#1674 <https://github.com/fmtlib/fmt/pull/1674>`_,
|
||
`#1677 <https://github.com/fmtlib/fmt/pull/1677>`_).
|
||
Thanks `@vsolontsov-ll (Vladimir Solontsov)
|
||
<https://github.com/vsolontsov-ll>`_.
|
||
|
||
* Added support for the ``'c'`` format specifier to integral types for
|
||
compatibility with ``std::format``
|
||
(`#1652 <https://github.com/fmtlib/fmt/issues/1652>`_).
|
||
|
||
* Replaced the ``'n'`` format specifier with ``'L'`` for compatibility with
|
||
``std::format`` (`#1624 <https://github.com/fmtlib/fmt/issues/1624>`_).
|
||
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``
|
||
* ``format_arg_store::types``
|
||
* ``*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``
|
||
(`#1538 <https://github.com/fmtlib/fmt/issues/1538>`_). 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
|
||
(`#1595 <https://github.com/fmtlib/fmt/issues/1595>`_,
|
||
`#1682 <https://github.com/fmtlib/fmt/pull/1682>`_,

||
`#1687 <https://github.com/fmtlib/fmt/pull/1687>`_,

||
`#1699 <https://github.com/fmtlib/fmt/pull/1699>`_).
|
||
Thanks `@rimathia <https://github.com/rimathia>`_.
|
||
|
||
* Fixed handling of ``operator<<`` overloads that use ``copyfmt``
|
||
(`#1666 <https://github.com/fmtlib/fmt/issues/1666>`_).
|
||
|
||
* Added the ``FMT_OS`` CMake option to control inclusion of OS-specific APIs
|
||
in the fmt target. This can be useful for embedded platforms
|
||
(`#1654 <https://github.com/fmtlib/fmt/issues/1654>`_,
|
||
`#1656 <https://github.com/fmtlib/fmt/pull/1656>`_).
|
||
Thanks `@kwesolowski (Krzysztof Wesolowski)
|
||
<https://github.com/kwesolowski>`_.
|
||
|
||
* Replaced ``FUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION`` with the ``FMT_FUZZ``
|
||
macro to prevent interferring with fuzzing of projects using {fmt}
|
||
(`#1650 <https://github.com/fmtlib/fmt/pull/1650>`_).
|
||
Thanks `@asraa (Asra Ali) <https://github.com/asraa>`_.
|
||
|
||
* Fixed compatibility with emscripten
|
||
(`#1636 <https://github.com/fmtlib/fmt/issues/1636>`_,
|
||
`#1637 <https://github.com/fmtlib/fmt/pull/1637>`_).
|

6.2.1 - 2020-05-09
|
||
------------------
|
||
|
||
* Fixed ostream support in ``sprintf``
|
||
(`#1631 <https://github.com/fmtlib/fmt/issues/1631>`_).
|
||
|
||
* Fixed type detection when using implicit conversion to ``string_view`` and
|
||
ostream ``operator<<`` inconsistently
|
||
(`#1662 <https://github.com/fmtlib/fmt/issues/1662>`_).
|
||
|
||
6.2.0 - 2020-04-05
|
||
------------------
|
||
|
||
* Improved error reporting when trying to format an object of a non-formattable
|
||
type:
|
||
|
||
.. code:: c++
|
||
|
||
fmt::format("{}", S());
|
||
|
||
now gives::
|
||
|
||
include/fmt/core.h:1015:5: error: static_assert failed due to requirement
|
||
'formattable' "Cannot format argument. To make type T formattable provide a
|
||
formatter<T> specialization:
|
||
https://fmt.dev/latest/api.html#formatting-user-defined-types"
|
||
static_assert(
|
||
^
|
||
...
|
||
note: in instantiation of function template specialization
|
||
'fmt::v6::format<char [3], S, char>' requested here
|
||
fmt::format("{}", S());
|
||
^
|
||
|
||
if ``S`` is not formattable.
|
||
|
||
* Reduced the library size by ~10%.
|
||
|
||
* Always print decimal point if ``#`` is specified
|
||
(`#1476 <https://github.com/fmtlib/fmt/issues/1476>`_,
|
||
`#1498 <https://github.com/fmtlib/fmt/issues/1498>`_):
|
||
|
||
.. code:: c++
|
||
|
||
fmt::print("{:#.0f}", 42.0);
|
||
|
||
now prints ``42.``
|
||
|
||
* 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.
|
||
|
||
* Added precision overflow detection in floating-point formatting.
|
||
|
||
* Implemented detection of invalid use of ``fmt::arg``.
|
||
|
||
* Used ``type_identity`` to block unnecessary template argument deduction.
|
||
Thanks Tim Song.
|
||
|
||
* Improved UTF-8 handling
|
||
(`#1109 <https://github.com/fmtlib/fmt/issues/1109>`_):
|
||
|
||
.. code:: c++
|
||
|
||
fmt::print("┌{0:─^{2}}┐\n"
|
||
"│{1: ^{2}}│\n"
|
||
"└{0:─^{2}}┘\n", "", "Привет, мир!", 20);
|
||
|
||
now prints::
|
||
|
||
┌────────────────────┐
|
||
│ Привет, мир! │
|
||
└────────────────────┘
|
||
|
||
on systems that support Unicode.
|
||
|
||
* Added experimental dynamic argument storage
|
||
(`#1170 <https://github.com/fmtlib/fmt/issues/1170>`_,
|
||
`#1584 <https://github.com/fmtlib/fmt/pull/1584>`_):
|
||
|
||
.. code:: c++
|
||
|
||
fmt::dynamic_format_arg_store<fmt::format_context> store;
|
||
store.push_back("answer");
|
||
store.push_back(42);
|
||
fmt::vprint("The {} is {}.\n", store);
|
||
|
||
prints::
|
||
|
||
The answer is 42.
|
||
|
||
Thanks `@vsolontsov-ll (Vladimir Solontsov)
|
||
<https://github.com/vsolontsov-ll>`_.
|
||
|
||
* Made ``fmt::join`` accept ``initializer_list``
|
||
(`#1591 <https://github.com/fmtlib/fmt/pull/1591>`_).

6.1.2 - 2019-12-11
|
||
------------------
|
||
|
||
* Fixed ABI compatibility with ``libfmt.so.6.0.0``
|
||
(`#1471 <https://github.com/fmtlib/fmt/issues/1471>`_).
|
||
|
||
* Fixed handling types convertible to ``std::string_view``
|
||
(`#1451 <https://github.com/fmtlib/fmt/pull/1451>`_).
|
||
Thanks `@denizevrenci (Deniz Evrenci) <https://github.com/denizevrenci>`_.
|
||
|
||
* Made CUDA test an opt-in enabled via the ``FMT_CUDA_TEST`` CMake option.
|
||
|
||
* Fixed sign conversion warnings
|
||
(`#1440 <https://github.com/fmtlib/fmt/pull/1440>`_).
|
||
Thanks `@0x8000-0000 (Florin Iucha) <https://github.com/0x8000-0000>`_.
|
||
|
||
6.1.1 - 2019-12-04
|
||
------------------
|
||
|
||
* Fixed shared library build on Windows
|
||
(`#1443 <https://github.com/fmtlib/fmt/pull/1443>`_,
|
||
`#1445 <https://github.com/fmtlib/fmt/issues/1445>`_,
|
||
`#1446 <https://github.com/fmtlib/fmt/pull/1446>`_,
|
||
`#1450 <https://github.com/fmtlib/fmt/issues/1450>`_).
|
||
Thanks `@egorpugin (Egor Pugin) <https://github.com/egorpugin>`_,
|
||
`@bbolli (Beat Bolli) <https://github.com/bbolli>`_.
|
||
|
||
* Added a missing decimal point in exponent notation with trailing zeros.
|
||
|
||
* Removed deprecated ``format_arg_store::TYPES``.
|
||
|
||
6.1.0 - 2019-12-01
|
||
------------------
|
||
|
||
* {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>`_:

|
||
|
||
* {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 <https://github.com/fmtlib/fmt/issues/1336>`_,
|
||
`#1353 <https://github.com/fmtlib/fmt/issues/1353>`_,
|
||
`#1360 <https://github.com/fmtlib/fmt/pull/1360>`_,
|
||
`#1361 <https://github.com/fmtlib/fmt/pull/1361>`_):
|
||
|
||
.. code:: c++
|
||
|
||
fmt::print("{}", 0.1f);
|
||
|
||
prints ``0.1`` instead of ``0.10000000149011612``.
|
||
|
||
Thanks `@orivej (Orivej Desh) <https://github.com/orivej>`_.
|
||
|
||
* Made floating-point formatting output consistent with ``printf``/iostreams
|
||
(`#1376 <https://github.com/fmtlib/fmt/issues/1376>`_,
|
||
`#1417 <https://github.com/fmtlib/fmt/issues/1417>`_).
|
||
|
||
* Added support for 128-bit integers
|
||
(`#1287 <https://github.com/fmtlib/fmt/pull/1287>`_):
|
||
|
||
.. code:: c++
|
||
|
||
fmt::print("{}", std::numeric_limits<__int128_t>::max());
|
||
|
||
prints ``170141183460469231731687303715884105727``.
|
||
|
||
Thanks `@denizevrenci (Deniz Evrenci) <https://github.com/denizevrenci>`_.
|
||
|
||
* The overload of ``print`` that takes ``text_style`` is now atomic, i.e. the
|
||
output from different threads doesn't interleave
|
||
(`#1351 <https://github.com/fmtlib/fmt/pull/1351>`_).
|
||
Thanks `@tankiJong (Tanki Zhang) <https://github.com/tankiJong>`_.
|
||
|
||
* 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 <https://github.com/fmtlib/fmt/issues/1322>`_,
|
||
`#1330 <https://github.com/fmtlib/fmt/pull/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)``.
|
||
|
||
Thanks `@jeremyong (Jeremy Ong) <https://github.com/jeremyong>`_.
|
||
|
||
* Changed formatting of octal zero with prefix from "00" to "0":
|
||
|
||
.. code:: c++
|
||
|
||
fmt::print("{:#o}", 0);
|
||
|
||
prints ``0``.
|
||
|
||
* The locale is now passed to ostream insertion (``<<``) operators
|
||
(`#1406 <https://github.com/fmtlib/fmt/pull/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"
|
||
}
|
||
|
||
Thanks `@dlaugt (Daniel Laügt) <https://github.com/dlaugt>`_.
|
||
|
||
* Locale-specific number formatting now uses grouping
|
||
(`#1393 <https://github.com/fmtlib/fmt/issues/1393>`_
|
||
`#1394 <https://github.com/fmtlib/fmt/pull/1394>`_).
|
||
Thanks `@skrdaniel <https://github.com/skrdaniel>`_.
|
||
|
||
* Fixed handling of types with deleted implicit rvalue conversion to
|
||
``const char**`` (`#1421 <https://github.com/fmtlib/fmt/issues/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 <https://github.com/fmtlib/fmt/pull/1286>`_).
|
||
Thanks `@agmt (Egor Seredin) <https://github.com/agmt>`_.
|
||
|
||
* Enum classes are no longer implicitly converted to ``int``
|
||
(`#1424 <https://github.com/fmtlib/fmt/issues/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 <https://github.com/fmtlib/fmt/issues/1389>`_,
|
||
`#1390 <https://github.com/fmtlib/fmt/pull/1390>`_).
|
||
Thanks `@tajtiattila (Attila Tajti) <https://github.com/tajtiattila>`_.
|
||
|
||
* {fmt} can now be installed on Linux, macOS and Windows with
|
||
`Conda <https://docs.conda.io/en/latest/>`__ using its

6.0.0 - 2019-08-26
|
||
------------------
|
||
|
||
* Switched to the `MIT license
|
||
<https://github.com/fmtlib/fmt/blob/5a4b24613ba16cc689977c3b5bd8274a3ba1dd1f/LICENSE.rst>`_
|
||
with an optional exception that allows distributing binary code without
|
||
attribution.
|
||
|
||
* Floating-point formatting is now locale-independent by default:
|
||
|
||
.. code:: c++
|
||
|
||
#include <locale>
|
||
#include <fmt/core.h>
|
||
|
||
int main() {
|
||
std::locale::global(std::locale("ru_RU.UTF-8"));
|
||
fmt::print("value = {}", 4.2);
|
||
}
|
||
|
||
prints "value = 4.2" regardless of the locale.
|
||
|
||
For locale-specific formatting use the ``n`` specifier:
|
||
|
||
.. code:: c++
|
||
|
||
std::locale::global(std::locale("ru_RU.UTF-8"));
|
||
fmt::print("value = {:n}", 4.2);
|
||
|
||
prints "value = 4,2".
|
||
|
||
* Added an experimental Grisu floating-point formatting algorithm
|
||
implementation (disabled by default). To enable it compile with the
|
||
``FMT_USE_GRISU`` macro defined to 1:
|
||
|
||
.. code:: c++
|
||
|
||
#define FMT_USE_GRISU 1
|
||
#include <fmt/format.h>
|
||
|
||
auto s = fmt::format("{}", 4.2); // formats 4.2 using Grisu
|
||
|
||
With Grisu enabled, {fmt} is 13x faster than ``std::ostringstream`` (libc++)
|
||
and 10x faster than ``sprintf`` on `dtoa-benchmark
|
||
<https://github.com/fmtlib/dtoa-benchmark>`_ (`full results
|
||
<https://fmt.dev/unknown_mac64_clang10.0.html>`_):
|
||
|
||
.. image:: https://user-images.githubusercontent.com/576385/
|
||
54883977-9fe8c000-4e28-11e9-8bde-272d122e7c52.jpg
|
||
|
||
* Separated formatting and parsing contexts for consistency with
|
||
`C++20 std::format <http://eel.is/c++draft/format>`_, removing the
|
||
undocumented ``basic_format_context::parse_context()`` function.
|
||
|
||
* Added `oss-fuzz <https://github.com/google/oss-fuzz>`_ support
|
||
(`#1199 <https://github.com/fmtlib/fmt/pull/1199>`_).
|
||
Thanks `@pauldreik (Paul Dreik) <https://github.com/pauldreik>`_.
|
||
|
||
* ``formatter`` specializations now always take precedence over ``operator<<``
|
||
(`#952 <https://github.com/fmtlib/fmt/issues/952>`_):
|
||
|
||
.. code:: c++
|
||
|
||
#include <iostream>
|
||
#include <fmt/ostream.h>
|
||
|
||
struct S {};
|
||
|
||
std::ostream& operator<<(std::ostream& os, S) {
|
||
return os << 1;
|
||
}
|
||
|
||
template <>
|
||
struct fmt::formatter<S> : fmt::formatter<int> {
|
||
auto format(S, format_context& ctx) {
|
||
return formatter<int>::format(2, ctx);
|
||
}
|
||
};
|
||
|
||
int main() {
|
||
std::cout << S() << "\n"; // prints 1 using operator<<
|
||
fmt::print("{}\n", S()); // prints 2 using formatter
|
||
}
|
||
|
||
* Introduced the experimental ``fmt::compile`` function that does format string
|
||
compilation (`#618 <https://github.com/fmtlib/fmt/issues/618>`_,
|
||
`#1169 <https://github.com/fmtlib/fmt/issues/1169>`_,
|
||
`#1171 <https://github.com/fmtlib/fmt/pull/1171>`_):
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/compile.h>
|
||
|
||
auto f = fmt::compile<int>("{}");
|
||
std::string s = fmt::format(f, 42); // can be called multiple times to
|
||
// format different values
|
||
// s == "42"
|
||
|
||
It moves the cost of parsing a format string outside of the format function
|
||
which can be beneficial when identically formatting many objects of the same
|
||
types. Thanks `@stryku (Mateusz Janek) <https://github.com/stryku>`_.
|
||
|
||
* Added experimental ``%`` format specifier that formats floating-point values
|
||
as percentages (`#1060 <https://github.com/fmtlib/fmt/pull/1060>`_,
|
||
`#1069 <https://github.com/fmtlib/fmt/pull/1069>`_,
|
||
`#1071 <https://github.com/fmtlib/fmt/pull/1071>`_):
|
||
|
||
.. code:: c++
|
||
|
||
auto s = fmt::format("{:.1%}", 0.42); // s == "42.0%"
|
||
|
||
Thanks `@gawain-bolton (Gawain Bolton) <https://github.com/gawain-bolton>`_.
|
||
|
||
* Implemented precision for floating-point durations
|
||
(`#1004 <https://github.com/fmtlib/fmt/issues/1004>`_,
|
||
`#1012 <https://github.com/fmtlib/fmt/pull/1012>`_):
|
||
|
||
.. code:: c++
|
||
|
||
auto s = fmt::format("{:.1}", std::chrono::duration<double>(1.234));
|
||
// s == 1.2s
|
||
|
||
Thanks `@DanielaE (Daniela Engert) <https://github.com/DanielaE>`_.
|
||
|
||
* Implemented ``chrono`` format specifiers ``%Q`` and ``%q`` that give the value
|
||
and the unit respectively (`#1019 <https://github.com/fmtlib/fmt/pull/1019>`_):
|
||
|
||
.. code:: c++
|
||
|
||
auto value = fmt::format("{:%Q}", 42s); // value == "42"
|
||
auto unit = fmt::format("{:%q}", 42s); // unit == "s"
|
||
|
||
Thanks `@DanielaE (Daniela Engert) <https://github.com/DanielaE>`_.
|
||
|
||
* Fixed handling of dynamic width in chrono formatter:
|
||
|
||
.. code:: c++
|
||
|
||
auto s = fmt::format("{0:{1}%H:%M:%S}", std::chrono::seconds(12345), 12);
|
||
// ^ width argument index ^ width
|
||
// s == "03:25:45 "
|
||
|
||
Thanks Howard Hinnant.
|
||
|
||
* Removed deprecated ``fmt/time.h``. Use ``fmt/chrono.h`` instead.
|
||
|
||
* Added ``fmt::format`` and ``fmt::vformat`` overloads that take ``text_style``
|
||
(`#993 <https://github.com/fmtlib/fmt/issues/993>`_,
|
||
`#994 <https://github.com/fmtlib/fmt/pull/994>`_):
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/color.h>
|
||
|
||
std::string message = fmt::format(fmt::emphasis::bold | fg(fmt::color::red),
|
||
"The answer is {}.", 42);
|
||
|
||
Thanks `@Naios (Denis Blank) <https://github.com/Naios>`_.
|
||
|
||
* Removed the deprecated color API (``print_colored``). Use the new API, namely
|
||
``print`` overloads that take ``text_style`` instead.
|
||
|
||
* Made ``std::unique_ptr`` and ``std::shared_ptr`` formattable as pointers via
|
||
``fmt::ptr`` (`#1121 <https://github.com/fmtlib/fmt/pull/1121>`_):
|
||
|
||
.. code:: c++
|
||
|
||
std::unique_ptr<int> p = ...;
|
||
fmt::print("{}", fmt::ptr(p)); // prints p as a pointer
|
||
|
||
Thanks `@sighingnow (Tao He) <https://github.com/sighingnow>`_.
|
||
|
||
* Made ``print`` and ``vprint`` report I/O errors
|
||
(`#1098 <https://github.com/fmtlib/fmt/issues/1098>`_,
|
||
`#1099 <https://github.com/fmtlib/fmt/pull/1099>`_).
|
||
Thanks `@BillyDonahue (Billy Donahue) <https://github.com/BillyDonahue>`_.
|
||
|
||
* Marked deprecated APIs with the ``[[deprecated]]`` attribute and removed
|
||
internal uses of deprecated APIs
|
||
(`#1022 <https://github.com/fmtlib/fmt/pull/1022>`_).
|
||
Thanks `@eliaskosunen (Elias Kosunen) <https://github.com/eliaskosunen>`_.
|
||
|
||
* Modernized the codebase using more C++11 features and removing workarounds.
|
||
Most importantly, ``buffer_context`` is now an alias template, so
|
||
use ``buffer_context<T>`` instead of ``buffer_context<T>::type``.
|
||
These features require GCC 4.8 or later.
|
||
|
||
* ``formatter`` specializations now always take precedence over implicit
|
||
conversions to ``int`` and the undocumented ``convert_to_int`` trait
|
||
is now deprecated.
|
||
|
||
* Moved the undocumented ``basic_writer``, ``writer``, and ``wwriter`` types
|
||
to the ``internal`` namespace.
|
||
|
||
* Removed deprecated ``basic_format_context::begin()``. Use ``out()`` instead.
|
||
|
||
* Disallowed passing the result of ``join`` as an lvalue to prevent misuse.
|
||
|
||
* Refactored the undocumented structs that represent parsed format specifiers
|
||
to simplify the API and allow multibyte fill.
|
||
|
||
* Moved SFINAE to template parameters to reduce symbol sizes.
|
||
|
||
* Switched to ``fputws`` for writing wide strings so that it's no longer
|
||
required to call ``_setmode`` on Windows
|
||
(`#1229 <https://github.com/fmtlib/fmt/issues/1229>`_,
|
||
`#1243 <https://github.com/fmtlib/fmt/pull/1243>`_).
|
||
Thanks `@jackoalan (Jack Andersen) <https://github.com/jackoalan>`_.
|
||
|
||
* Improved literal-based API
|
||
(`#1254 <https://github.com/fmtlib/fmt/pull/1254>`_).
|
||
Thanks `@sylveon (Charles Milette) <https://github.com/sylveon>`_.
|
||
|
||
* Added support for exotic platforms without ``uintptr_t`` such as IBM i
|
||
(AS/400) which has 128-bit pointers and only 64-bit integers
|
||
(`#1059 <https://github.com/fmtlib/fmt/issues/1059>`_).
|
||
|
||
* Added `Sublime Text syntax highlighting config
|
||
<https://github.com/fmtlib/fmt/blob/master/support/C%2B%2B.sublime-syntax>`_
|
||
(`#1037 <https://github.com/fmtlib/fmt/issues/1037>`_).
|
||
Thanks `@Kronuz (Germán Méndez Bravo) <https://github.com/Kronuz>`_.
|
||
|
||
* Added the ``FMT_ENFORCE_COMPILE_STRING`` macro to enforce the use of
|
||
compile-time format strings
|
||
(`#1231 <https://github.com/fmtlib/fmt/pull/1231>`_).
|
||
Thanks `@jackoalan (Jack Andersen) <https://github.com/jackoalan>`_.
|
||
|
||
* Stopped setting ``CMAKE_BUILD_TYPE`` if {fmt} is a subproject
|
||
(`#1081 <https://github.com/fmtlib/fmt/issues/1081>`_).
|
||
|
||

5.3.0 - 2018-12-28
|
||
------------------
|
||
|
||
* Introduced experimental chrono formatting support:
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/chrono.h>
|
||
|
||
int main() {
|
||
using namespace std::literals::chrono_literals;
|
||
fmt::print("Default format: {} {}\n", 42s, 100ms);
|
||
fmt::print("strftime-like format: {:%H:%M:%S}\n", 3h + 15min + 30s);
|
||
}
|
||
|
||
prints::
|
||
|
||
Default format: 42s 100ms
|
||
strftime-like format: 03:15:30
|
||
|
||
* Added experimental support for emphasis (bold, italic, underline,
|
||
strikethrough), colored output to a file stream, and improved colored
|
||
formatting API
|
||
(`#961 <https://github.com/fmtlib/fmt/pull/961>`_,
|
||
`#967 <https://github.com/fmtlib/fmt/pull/967>`_,
|
||
`#973 <https://github.com/fmtlib/fmt/pull/973>`_):
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/color.h>
|
||
|
||
int main() {
|
||
print(fg(fmt::color::crimson) | fmt::emphasis::bold,
|
||
"Hello, {}!\n", "world");
|
||
print(fg(fmt::color::floral_white) | bg(fmt::color::slate_gray) |
|
||
fmt::emphasis::underline, "Hello, {}!\n", "мир");
|
||
print(fg(fmt::color::steel_blue) | fmt::emphasis::italic,
|
||
"Hello, {}!\n", "世界");
|
||
}
|
||
|
||
prints the following on modern terminals with RGB color support:

|
||
|
||
Thanks `@Rakete1111 (Nicolas) <https://github.com/Rakete1111>`_.
|
||
|
||
* Added support for 4-bit terminal colors
|
||
(`#968 <https://github.com/fmtlib/fmt/issues/968>`_,
|
||
`#974 <https://github.com/fmtlib/fmt/pull/974>`_)
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/color.h>
|
||
|
||
int main() {
|
||
print(fg(fmt::terminal_color::red), "stop\n");
|
||
}
|
||
|
||
Note that these colors vary by terminal:

|
||
|
||
Thanks `@Rakete1111 (Nicolas) <https://github.com/Rakete1111>`_.
|
||
|
||
* Parameterized formatting functions on the type of the format string
|
||
(`#880 <https://github.com/fmtlib/fmt/issues/880>`_,
|
||
`#881 <https://github.com/fmtlib/fmt/pull/881>`_,
|
||
`#883 <https://github.com/fmtlib/fmt/pull/883>`_,
|
||
`#885 <https://github.com/fmtlib/fmt/pull/885>`_,
|
||
`#897 <https://github.com/fmtlib/fmt/pull/897>`_,
|
||
`#920 <https://github.com/fmtlib/fmt/issues/920>`_).
|
||
Any object of type ``S`` that has an overloaded ``to_string_view(const S&)``
|
||
returning ``fmt::string_view`` can be used as a format string:
|
||
|
||
.. code:: c++
|
||
|
||
namespace my_ns {
|
||
inline string_view to_string_view(const my_string& s) {
|
||
return {s.data(), s.length()};
|
||
}
|
||
}
|
||
|
||
std::string message = fmt::format(my_string("The answer is {}."), 42);
|
||
|
||
Thanks `@DanielaE (Daniela Engert) <https://github.com/DanielaE>`_.
|
||
|
||
* Made ``std::string_view`` work as a format string
|
||
(`#898 <https://github.com/fmtlib/fmt/pull/898>`_):
|
||
|
||
.. code:: c++
|
||
|
||
auto message = fmt::format(std::string_view("The answer is {}."), 42);
|
||
|
||
Thanks `@DanielaE (Daniela Engert) <https://github.com/DanielaE>`_.
|
||
|
||
* Added wide string support to compile-time format string checks
|
||
(`#924 <https://github.com/fmtlib/fmt/pull/924>`_):
|
||
|
||
.. code:: c++
|
||
|
||
print(fmt(L"{:f}"), 42); // compile-time error: invalid type specifier
|
||
|
||
Thanks `@XZiar <https://github.com/XZiar>`_.
|
||
|
||
* Made colored print functions work with wide strings
|
||
(`#867 <https://github.com/fmtlib/fmt/pull/867>`_):
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/color.h>
|
||
|
||
int main() {
|
||
print(fg(fmt::color::red), L"{}\n", 42);
|
||
}
|
||
|
||
Thanks `@DanielaE (Daniela Engert) <https://github.com/DanielaE>`_.
|
||
|
||
* Introduced experimental Unicode support
|
||
(`#628 <https://github.com/fmtlib/fmt/issues/628>`_,
|
||
`#891 <https://github.com/fmtlib/fmt/pull/891>`_):
|
||
|
||
.. code:: c++
|
||
|
||
using namespace fmt::literals;
|
||
auto s = fmt::format("{:*^5}"_u, "🤡"_u); // s == "**🤡**"_u
|
||
|
||
* Improved locale support:
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/locale.h>
|
||
|
||
struct numpunct : std::numpunct<char> {
|
||
protected:
|
||
char do_thousands_sep() const override { return '~'; }
|
||
};
|
||
|
||
std::locale loc;
|
||
auto s = fmt::format(std::locale(loc, new numpunct()), "{:n}", 1234567);
|
||
// s == "1~234~567"
|
||
|
||
* Constrained formatting functions on proper iterator types
|
||
(`#921 <https://github.com/fmtlib/fmt/pull/921>`_).
|
||
Thanks `@DanielaE (Daniela Engert) <https://github.com/DanielaE>`_.
|
||
|
||
* Added ``make_printf_args`` and ``make_wprintf_args`` functions
|
||
(`#934 <https://github.com/fmtlib/fmt/pull/934>`_).
|
||
Thanks `@tnovotny <https://github.com/tnovotny>`_.
|
||
|
||
* Deprecated ``fmt::visit``, ``parse_context``, and ``wparse_context``.
|
||
Use ``fmt::visit_format_arg``, ``format_parse_context``, and
|
||
``wformat_parse_context`` instead.
|
||
|
||
* Removed undocumented ``basic_fixed_buffer`` which has been superseded by the
|
||
iterator-based API
|
||
(`#873 <https://github.com/fmtlib/fmt/issues/873>`_,
|
||
`#902 <https://github.com/fmtlib/fmt/pull/902>`_).
|
||
Thanks `@superfunc (hollywood programmer) <https://github.com/superfunc>`_.
|
||
|
||
* Disallowed repeated leading zeros in an argument ID:
|
||
|
||
.. code:: c++
|
||
|
||
fmt::print("{000}", 42); // error
|
||
|
||
* Reintroduced support for gcc 4.4.
|
||
|
||
* Fixed compilation on platforms with exotic ``double``
|
||
(`#878 <https://github.com/fmtlib/fmt/issues/878>`_).

5.2.1 - 2018-09-21
|
||
------------------
|
||
|
||
* Fixed ``visit`` lookup issues on gcc 7 & 8
|
||
(`#870 <https://github.com/fmtlib/fmt/pull/870>`_).
|
||
Thanks `@medithe <https://github.com/medithe>`_.
|
||
|
||
* Fixed linkage errors on older gcc.
|
||
|
||
* Prevented ``fmt/range.h`` from specializing ``fmt::basic_string_view``
|
||
(`#865 <https://github.com/fmtlib/fmt/issues/865>`_,
|
||
`#868 <https://github.com/fmtlib/fmt/pull/868>`_).
|
||
Thanks `@hhggit (dual) <https://github.com/hhggit>`_.
|
||
|
||
* Improved error message when formatting unknown types
|
||
(`#872 <https://github.com/fmtlib/fmt/pull/872>`_).
|
||
Thanks `@foonathan (Jonathan Müller) <https://github.com/foonathan>`_,
|
||
|
||
* Disabled templated user-defined literals when compiled under nvcc
|
||
(`#875 <https://github.com/fmtlib/fmt/pull/875>`_).
|
||
Thanks `@CandyGumdrop (Candy Gumdrop) <https://github.com/CandyGumdrop>`_,
|
||
|
||
* Fixed ``format_to`` formatting to ``wmemory_buffer``
|
||
(`#874 <https://github.com/fmtlib/fmt/issues/874>`_).
|
||
|
||
5.2.0 - 2018-09-13
|
||
------------------
|
||
|
||
* Optimized format string parsing and argument processing which resulted in up
|
||
to 5x speed up on long format strings and significant performance boost on
|
||
various benchmarks. For example, version 5.2 is 2.22x faster than 5.1 on
|
||
decimal integer formatting with ``format_to`` (macOS, clang-902.0.39.2):
|
||
|
||
================== ======= =======
|
||
Method Time, s Speedup
|
||
================== ======= =======
|
||
fmt::format 5.1 0.58
|
||
fmt::format 5.2 0.35 1.66x
|
||
fmt::format_to 5.1 0.51
|
||
fmt::format_to 5.2 0.23 2.22x
|
||
sprintf 0.71
|
||
std::to_string 1.01
|
||
std::stringstream 1.73
|
||
================== ======= =======
|
||
|
||
* Changed the ``fmt`` macro from opt-out to opt-in to prevent name collisions.
|
||
To enable it define the ``FMT_STRING_ALIAS`` macro to 1 before including
|
||
``fmt/format.h``:
|
||
|
||
.. code:: c++
|
||
|
||
#define FMT_STRING_ALIAS 1
|
||
#include <fmt/format.h>
|
||
std::string answer = format(fmt("{}"), 42);
|
||
|
||
* Added compile-time format string checks to ``format_to`` overload that takes
|
||
``fmt::memory_buffer`` (`#783 <https://github.com/fmtlib/fmt/issues/783>`_):
|
||
|
||
.. code:: c++
|
||
|
||
fmt::memory_buffer buf;
|
||
// Compile-time error: invalid type specifier.
|
||
fmt::format_to(buf, fmt("{:d}"), "foo");
|
||
|
||
* Moved experimental color support to ``fmt/color.h`` and enabled the
|
||
new API by default. The old API can be enabled by defining the
|
||
``FMT_DEPRECATED_COLORS`` macro.
|
||
|
||
* Added formatting support for types explicitly convertible to
|
||
``fmt::string_view``:
|
||
|
||
.. code:: c++
|
||
|
||
struct foo {
|
||
explicit operator fmt::string_view() const { return "foo"; }
|
||
};
|
||
auto s = format("{}", foo());
|
||
|
||
In particular, this makes formatting function work with
|
||
``folly::StringPiece``.
|
||
|
||
* Implemented preliminary support for ``char*_t`` by replacing the ``format``
|
||
function overloads with a single function template parameterized on the string
|
||
type.
|
||
|
||
* Added support for dynamic argument lists
|
||
(`#814 <https://github.com/fmtlib/fmt/issues/814>`_,

||
`#819 <https://github.com/fmtlib/fmt/pull/819>`_).
|
||
Thanks `@MikePopoloski (Michael Popoloski)
|
||
<https://github.com/MikePopoloski>`_.
|
||
|
||
* Reduced executable size overhead for embedded targets using newlib nano by
|
||
making locale dependency optional
|
||
(`#839 <https://github.com/fmtlib/fmt/pull/839>`_).
|
||
Thanks `@teajay-fr (Thomas Benard) <https://github.com/teajay-fr>`_.
|
||
|
||
* Keep ``noexcept`` specifier when exceptions are disabled
|
||

|
||
`#810 <https://github.com/fmtlib/fmt/pull/810>`_).
|
||
Thanks `@qis (Alexej Harm) <https://github.com/qis>`_.
|
||
|
||
* Fixed formatting of user-defined types providing ``operator<<`` with
|
||
``format_to_n``
|
||
(`#806 <https://github.com/fmtlib/fmt/pull/806>`_).
|
||
Thanks `@mkurdej (Marek Kurdej) <https://github.com/mkurdej>`_.
|
||
|
||
* Fixed dynamic linkage of new symbols
|
||
(`#808 <https://github.com/fmtlib/fmt/issues/808>`_).
|
||
|
||
* Fixed global initialization issue
|
||

|
||
|
||
.. code:: c++
|
||
|
||
// This works on compilers with constexpr support.
|
||
static const std::string answer = fmt::format("{}", 42);
|
||
|
||
* Fixed various compiler warnings and errors

5.1.0 - 2018-07-05
|
||
------------------
|
||
|
||
* Added experimental support for RGB color output enabled with
|
||
the ``FMT_EXTENDED_COLORS`` macro:
|
||
|
||
.. code:: c++
|
||
|
||
#define FMT_EXTENDED_COLORS
|
||
#define FMT_HEADER_ONLY // or compile fmt with FMT_EXTENDED_COLORS defined
|
||
#include <fmt/format.h>
|
||
|
||
fmt::print(fmt::color::steel_blue, "Some beautiful text");
|
||
|
||
The old API (the ``print_colored`` and ``vprint_colored`` functions and the
|
||
``color`` enum) is now deprecated.
|
||
(`#762 <https://github.com/fmtlib/fmt/issues/762>`_

|
||
Thanks `@Remotion (Remo) <https://github.com/Remotion>`_.
|
||
|
||
* Made ``format_to`` work with ``basic_memory_buffer``
|
||
(`#776 <https://github.com/fmtlib/fmt/issues/776>`_).
|
||
|
||
* Added ``vformat_to_n`` and ``wchar_t`` overload of ``format_to_n``
|
||
(`#764 <https://github.com/fmtlib/fmt/issues/764>`_,
|
||
`#769 <https://github.com/fmtlib/fmt/issues/769>`_).
|
||
|
||
* Made ``is_range`` and ``is_tuple_like`` part of public (experimental) API
|
||
to allow specialization for user-defined types
|
||
(`#751 <https://github.com/fmtlib/fmt/issues/751>`_,
|
||
`#759 <https://github.com/fmtlib/fmt/pull/759>`_).
|
||
Thanks `@drrlvn (Dror Levin) <https://github.com/drrlvn>`_.
|
||
|
||
* Added more compilers to continuous integration and increased ``FMT_PEDANTIC``
|
||
warning levels
|
||
(`#736 <https://github.com/fmtlib/fmt/pull/736>`_).
|
||
Thanks `@eliaskosunen (Elias Kosunen) <https://github.com/eliaskosunen>`_.
|
||
|
||
* Fixed compilation with MSVC 2013.
|
||
|

* Fixed handling of user-defined types in ``format_to``
|
||
(`#793 <https://github.com/fmtlib/fmt/issues/793>`_).
|
||
|
||
* Forced linking of inline ``vformat`` functions into the library
|

(`#750 <https://github.com/fmtlib/fmt/issues/750>`_).
|
||
|
||
* Fixed floating-point formatting to a non-back_insert_iterator with sign &
|
||
numeric alignment specified
|
||
(`#756 <https://github.com/fmtlib/fmt/issues/756>`_).
|
||
|
||
* Fixed formatting to an array with ``format_to_n``
|
||
(`#778 <https://github.com/fmtlib/fmt/issues/778>`_).
|
||
|
||
* Fixed formatting of more than 15 named arguments
|

|
||
5.0.0 - 2018-05-21
|
||
------------------
|
||
|
||
* Added a requirement for partial C++11 support, most importantly variadic
|
||
templates and type traits, and dropped ``FMT_VARIADIC_*`` emulation macros.
|
||
Variadic templates are available since GCC 4.4, Clang 2.9 and MSVC 18.0 (2013).
|
||
For older compilers use {fmt} `version 4.x
|
||
<https://github.com/fmtlib/fmt/releases/tag/4.1.0>`_ which continues to be
|
||
maintained and works with C++98 compilers.
|
||
|
||
* Renamed symbols to follow standard C++ naming conventions and proposed a subset
|
||
of the library for standardization in `P0645R2 Text Formatting
|
||
<https://wg21.link/P0645>`_.
|
||
|
||
* Implemented ``constexpr`` parsing of format strings and `compile-time format
|
||
string checks
|
||
<https://fmt.dev/latest/api.html#compile-time-format-string-checks>`_. For
|
||
example
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/format.h>
|
||
|
||
std::string s = format(fmt("{:d}"), "foo");
|
||
|
||
gives a compile-time error because ``d`` is an invalid specifier for strings
|
||
(`godbolt <https://godbolt.org/g/rnCy9Q>`__)::
|
||
|
||
...
|
||
<source>:4:19: note: in instantiation of function template specialization 'fmt::v5::format<S, char [4]>' requested here
|
||
std::string s = format(fmt("{:d}"), "foo");
|
||
^
|
||
format.h:1337:13: note: non-constexpr function 'on_error' cannot be used in a constant expression
|
||
handler.on_error("invalid type specifier");
|
||
|
||
Compile-time checks require relaxed ``constexpr`` (C++14 feature) support. If
|
||
the latter is not available, checks will be performed at runtime.
|
||
|
||
* Separated format string parsing and formatting in the extension API to enable
|
||
compile-time format string processing. For example
|
||
|
||
.. code:: c++
|
||
|
||
struct Answer {};
|
||
|
||
namespace fmt {
|
||
template <>
|
||
struct formatter<Answer> {
|
||
constexpr auto parse(parse_context& ctx) {
|
||
auto it = ctx.begin();
|
||
spec = *it;
|
||
if (spec != 'd' && spec != 's')
|
||
throw format_error("invalid specifier");
|
||
return ++it;
|
||
}
|
||
|
||
template <typename FormatContext>
|
||
auto format(Answer, FormatContext& ctx) {
|
||
return spec == 's' ?
|
||
format_to(ctx.begin(), "{}", "fourty-two") :
|
||
format_to(ctx.begin(), "{}", 42);
|
||
}
|
||
|
||
char spec = 0;
|
||
};
|
||
}
|
||
|
||
std::string s = format(fmt("{:x}"), Answer());
|
||
|
||
gives a compile-time error due to invalid format specifier (`godbolt
|
||
<https://godbolt.org/g/2jQ1Dv>`__)::
|
||
|
||
...
|
||
<source>:12:45: error: expression '<throw-expression>' is not a constant expression
|
||
throw format_error("invalid specifier");
|
||
|
||
* Added `iterator support
|
||
<https://fmt.dev/latest/api.html#output-iterator-support>`_:
|
||
|
||
.. code:: c++
|
||
|
||
#include <vector>
|
||
#include <fmt/format.h>
|
||
|
||
std::vector<char> out;
|
||
fmt::format_to(std::back_inserter(out), "{}", 42);
|
||
|
||
* Added the `format_to_n
|
||
<https://fmt.dev/latest/api.html#_CPPv2N3fmt11format_to_nE8OutputItNSt6size_tE11string_viewDpRK4Args>`_
|
||
function that restricts the output to the specified number of characters
|
||
(`#298 <https://github.com/fmtlib/fmt/issues/298>`_):
|
||
|
||
.. code:: c++
|
||
|
||
char out[4];
|
||
fmt::format_to_n(out, sizeof(out), "{}", 12345);
|
||
// out == "1234" (without terminating '\0')
|
||
|
||
* Added the `formatted_size
|
||
<https://fmt.dev/latest/api.html#_CPPv2N3fmt14formatted_sizeE11string_viewDpRK4Args>`_
|
||
function for computing the output size:
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/format.h>
|
||
|
||
auto size = fmt::formatted_size("{}", 12345); // size == 5
|
||
|
||
* Improved compile times by reducing dependencies on standard headers and
|
||
providing a lightweight `core API <https://fmt.dev/latest/api.html#core-api>`_:
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/core.h>
|
||
|
||
fmt::print("The answer is {}.", 42);
|
||
|
||
See `Compile time and code bloat
|
||
<https://github.com/fmtlib/fmt#compile-time-and-code-bloat>`_.
|
||
|
||
* Added the `make_format_args
|
||
<https://fmt.dev/latest/api.html#_CPPv2N3fmt16make_format_argsEDpRK4Args>`_
|
||
function for capturing formatting arguments:
|
||
|
||
.. code:: c++
|
||
|
||
// Prints formatted error message.
|
||
void vreport_error(const char *format, fmt::format_args args) {
|
||
fmt::print("Error: ");
|
||
fmt::vprint(format, args);
|
||
}
|
||
template <typename... Args>
|
||
void report_error(const char *format, const Args & ... args) {
|
||
vreport_error(format, fmt::make_format_args(args...));
|
||
}
|
||
|
||
* Added the ``make_printf_args`` function for capturing ``printf`` arguments
|
||
(`#687 <https://github.com/fmtlib/fmt/issues/687>`_,
|
||
`#694 <https://github.com/fmtlib/fmt/pull/694>`_).
|
||
Thanks `@Kronuz (Germán Méndez Bravo) <https://github.com/Kronuz>`_.
|
||
|
||
* Added prefix ``v`` to non-variadic functions taking ``format_args`` to
|
||
distinguish them from variadic ones:
|
||
|
||
.. code:: c++
|
||
|
||
std::string vformat(string_view format_str, format_args args);
|
||
|
||
template <typename... Args>
|
||
std::string format(string_view format_str, const Args & ... args);
|
||
|
||
* Added experimental support for formatting ranges, containers and tuple-like
|
||
types in ``fmt/ranges.h`` (`#735 <https://github.com/fmtlib/fmt/pull/735>`_):
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/ranges.h>
|
||
|
||
std::vector<int> v = {1, 2, 3};
|
||
fmt::print("{}", v); // prints {1, 2, 3}
|
||
|
||
Thanks `@Remotion (Remo) <https://github.com/Remotion>`_.
|
||
|
||
* Implemented ``wchar_t`` date and time formatting
|
||
(`#712 <https://github.com/fmtlib/fmt/pull/712>`_):
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/time.h>
|
||
|
||
std::time_t t = std::time(nullptr);
|
||
auto s = fmt::format(L"The date is {:%Y-%m-%d}.", *std::localtime(&t));
|
||
|
||
Thanks `@DanielaE (Daniela Engert) <https://github.com/DanielaE>`_.
|
||
|
||
* Provided more wide string overloads
|
||
(`#724 <https://github.com/fmtlib/fmt/pull/724>`_).
|
||
Thanks `@DanielaE (Daniela Engert) <https://github.com/DanielaE>`_.
|
||
|
||
* Switched from a custom null-terminated string view class to ``string_view``
|
||
in the format API and provided ``fmt::string_view`` which implements a subset
|
||
of ``std::string_view`` API for pre-C++17 systems.
|
||
|
||
* Added support for ``std::experimental::string_view``
|
||
(`#607 <https://github.com/fmtlib/fmt/pull/607>`_):
|
||
|
||
.. code:: c++
|
||
|
||
#include <fmt/core.h>
|
||
#include <experimental/string_view>
|
||
|
||
fmt::print("{}", std::experimental::string_view("foo"));
|
||
|
||
Thanks `@virgiliofornazin (Virgilio Alexandre Fornazin)
|
||
<https://github.com/virgiliofornazin>`__.
|
||
|
||
* Allowed mixing named and automatic arguments:
|
||
|
||
.. code:: c++
|
||
|
||
fmt::format("{} {two}", 1, fmt::arg("two", 2));
|
||
|
||
* Removed the write API in favor of the `format API
|
||
<https://fmt.dev/latest/api.html#format-api>`_ with compile-time handling of
|
||
format strings.
|
||
|
||
* Disallowed formatting of multibyte strings into a wide character target
|
||
(`#606 <https://github.com/fmtlib/fmt/pull/606>`_).
|
||
|
||
* Improved documentation
|
||
(`#515 <https://github.com/fmtlib/fmt/pull/515>`_,
|
||
`#614 <https://github.com/fmtlib/fmt/issues/614>`_,

|
||
`@johnthagen <https://github.com/johnthagen>`_.
|
||
|
||
* Implemented more efficient handling of large number of format arguments.
|
||
|
||
* Introduced an inline namespace for symbol versioning.
|
||
|
||
* Added debug postfix ``d`` to the ``fmt`` library name
|
||
(`#636 <https://github.com/fmtlib/fmt/issues/636>`_).
|
||
|
||
* Removed unnecessary ``fmt/`` prefix in includes
|
||
(`#397 <https://github.com/fmtlib/fmt/pull/397>`_).
|
||
Thanks `@chronoxor (Ivan Shynkarenka) <https://github.com/chronoxor>`_.
|
||
|
||
* Moved ``fmt/*.h`` to ``include/fmt/*.h`` to prevent irrelevant files and
|
||
directories appearing on the include search paths when fmt is used as a
|
||
subproject and moved source files to the ``src`` directory.
|
||
|
||
* Added qmake project file ``support/fmt.pro``
|
||
(`#641 <https://github.com/fmtlib/fmt/pull/641>`_).
|
||
Thanks `@cowo78 (Giuseppe Corbelli) <https://github.com/cowo78>`_.

|
||
|
||
* Removed ``FMT_CPPFORMAT`` CMake option.
|
||
|
||

|
||
(`#616 <https://github.com/fmtlib/fmt/pull/616>`_).
|
||
Thanks `@aroig (Abdó Roig-Maranges) <https://github.com/aroig>`_.
|
||
|
||
* Fixed handling of nested braces in ``fmt::join``
|
||
(`#638 <https://github.com/fmtlib/fmt/issues/638>`_).
|
||
|
||
* Added ``SOURCELINK_SUFFIX`` for compatibility with Sphinx 1.5
|
||
(`#497 <https://github.com/fmtlib/fmt/pull/497>`_).
|
||
Thanks `@ginggs (Graham Inggs) <https://github.com/ginggs>`_.
|
||
|
||
* Added a missing ``inline`` in the header-only mode
|
||
(`#626 <https://github.com/fmtlib/fmt/pull/626>`_).
|
||
Thanks `@aroig (Abdó Roig-Maranges) <https://github.com/aroig>`_.

3.0.0 - 2016-05-07
|
||
------------------
|
||
|
||
* The project has been renamed from C++ Format (cppformat) to fmt for
|
||
consistency with the used namespace and macro prefix
|
||
(`#307 <https://github.com/fmtlib/fmt/issues/307>`_).
|
||
Library headers are now located in the ``fmt`` directory:
|
||
|
||
.. code:: c++
|
||
|
||
#include "fmt/format.h"
|
||
|
||
Including ``format.h`` from the ``cppformat`` directory is deprecated
|
||
but works via a proxy header which will be removed in the next major version.
|
||
|
||
The documentation is now available at https://fmt.dev.
|
||
|
||
* Added support for `strftime <http://en.cppreference.com/w/cpp/chrono/c/strftime>`_-like
|
||
`date and time formatting <https://fmt.dev/3.0.0/api.html#date-and-time-formatting>`_
|
||
(`#283 <https://github.com/fmtlib/fmt/issues/283>`_):
|
||
|
||
.. code:: c++
|
||
|
||
#include "fmt/time.h"
|
||
|
||
std::time_t t = std::time(nullptr);
|
||
// Prints "The date is 2016-04-29." (with the current date)
|
||
fmt::print("The date is {:%Y-%m-%d}.", *std::localtime(&t));
|
||
|
||
* ``std::ostream`` support including formatting of user-defined types that provide
|
||
overloaded ``operator<<`` has been moved to ``fmt/ostream.h``:
|
||
|
||
.. code:: c++
|
||
|
||
#include "fmt/ostream.h"
|
||
|
||
class Date {
|
||
int year_, month_, day_;
|
||
public:
|
||
Date(int year, int month, int day) : year_(year), month_(month), day_(day) {}
|
||
|
||
friend std::ostream &operator<<(std::ostream &os, const Date &d) {
|
||
return os << d.year_ << '-' << d.month_ << '-' << d.day_;
|
||
}
|
||
};
|
||
|
||
std::string s = fmt::format("The date is {}", Date(2012, 12, 9));
|
||
// s == "The date is 2012-12-9"
|
||
|
||
* Added support for `custom argument formatters
|
||
<https://fmt.dev/3.0.0/api.html#argument-formatters>`_
|
||
(`#235 <https://github.com/fmtlib/fmt/issues/235>`_).
|
||
|
||
* Added support for locale-specific integer formatting with the ``n`` specifier
|
||
(`#305 <https://github.com/fmtlib/fmt/issues/305>`_):
|
||
|
||
.. code:: c++
|
||
|
||
std::setlocale(LC_ALL, "en_US.utf8");
|
||
fmt::print("cppformat: {:n}\n", 1234567); // prints 1,234,567
|
||
|
||
* Sign is now preserved when formatting an integer with an incorrect ``printf``
|
||
format specifier (`#265 <https://github.com/fmtlib/fmt/issues/265>`_):
|
||
|
||
.. code:: c++
|
||
|
||
fmt::printf("%lld", -42); // prints -42
|
||
|
||
Note that it would be an undefined behavior in ``std::printf``.
|
||
|
||
* Length modifiers such as ``ll`` are now optional in printf formatting
|
||
functions and the correct type is determined automatically
|
||
(`#255 <https://github.com/fmtlib/fmt/issues/255>`_):
|
||
|
||
.. code:: c++
|
||
|
||
fmt::printf("%d", std::numeric_limits<long long>::max());
|
||
|
||
Note that it would be an undefined behavior in ``std::printf``.
|
||
|
||
* Added initial support for custom formatters
|
||
(`#231 <https://github.com/fmtlib/fmt/issues/231>`_).
|
||
|
||
* Fixed detection of user-defined literal support on Intel C++ compiler
|
||
(`#311 <https://github.com/fmtlib/fmt/issues/311>`_,
|
||
`#312 <https://github.com/fmtlib/fmt/pull/312>`_).

------------------
|
||
|
||
* Project layout and build system improvements
|
||
(`#267 <https://github.com/fmtlib/fmt/pull/267>`_):
|

|
||
Including ``format.h`` from the top-level directory is deprecated
|
||
but works via a proxy header which will be removed in the next
|
||
major version.
|
||
|
||
* C++ Format CMake targets now have proper interface definitions.
|
||
|
||
* Installed version of the library now supports the header-only
|
||
configuration.
|
||
|
||
* Targets ``doc``, ``install``, and ``test`` are now disabled if C++ Format
|

is included as a CMake subproject. They can be enabled by setting
|
||
``FMT_DOC``, ``FMT_INSTALL``, and ``FMT_TEST`` in the parent project.
|
||
|

2.0.0 - 2015-12-01
|
||
------------------
|
||
|
||
General
|
||
~~~~~~~
|
||
|
||
* [Breaking] Named arguments
|
||
(`#169 <https://github.com/fmtlib/fmt/pull/169>`_,
|
||
`#173 <https://github.com/fmtlib/fmt/pull/173>`_,
|
||
`#174 <https://github.com/fmtlib/fmt/pull/174>`_):
|

fmt::print("The answer is {answer}.", fmt::arg("answer", 42));
|
||
|
||
Thanks to `@jamboree <https://github.com/jamboree>`_.
|
||
|
||
* [Experimental] User-defined literals for format and named arguments
|
||
(`#204 <https://github.com/fmtlib/fmt/pull/204>`_,
|
||
`#206 <https://github.com/fmtlib/fmt/pull/206>`_,
|
||
`#207 <https://github.com/fmtlib/fmt/pull/207>`_):
|
||
|
||
.. code:: c++
|
||
|
||
using namespace fmt::literals;
|
||
fmt::print("The answer is {answer}.", "answer"_a=42);
|
||
|
||
Thanks to `@dean0x7d (Dean Moldovan) <https://github.com/dean0x7d>`_.
|
||
|
||
* [Breaking] Formatting of more than 16 arguments is now supported when using
|
||
variadic templates
|
||
(`#141 <https://github.com/fmtlib/fmt/issues/141>`_).
|
||
Thanks to `@Shauren <https://github.com/Shauren>`_.
|
||
|
||
* Runtime width specification
|
||
(`#168 <https://github.com/fmtlib/fmt/pull/168>`_):
|
||
|
||
.. code:: c++
|
||
|
||
fmt::format("{0:{1}}", 42, 5); // gives " 42"
|
||
|
||
Thanks to `@jamboree <https://github.com/jamboree>`_.
|
||
|
||
* [Breaking] Enums are now formatted with an overloaded ``std::ostream`` insertion

(`#232 <https://github.com/fmtlib/fmt/issues/232>`_).
|
||
|
||
* [Breaking] Changed default ``bool`` format to textual, "true" or "false"
|
||
(`#170 <https://github.com/fmtlib/fmt/issues/170>`_):
|
||
|
||
.. code:: c++
|
||
|
||
fmt::print("{}", true); // prints "true"
|
||
|
||
To print ``bool`` as a number use numeric format specifier such as ``d``:
|
||
|
||
.. code:: c++
|
||
|
||
fmt::print("{:d}", true); // prints "1"
|
||
|
||
* ``fmt::printf`` and ``fmt::sprintf`` now support formatting of ``bool`` with the
|
||
``%s`` specifier giving textual output, "true" or "false"
|
||
(`#223 <https://github.com/fmtlib/fmt/pull/223>`_):
|
||
|
||
.. code:: c++
|
||
|
||
fmt::printf("%s", true); // prints "true"
|
||
|
||
Thanks to `@LarsGullik <https://github.com/LarsGullik>`_.
|
||
|
||
* [Breaking] ``signed char`` and ``unsigned char`` are now formatted as integers by default
|
||
(`#217 <https://github.com/fmtlib/fmt/pull/217>`_).

||
(`#223 <https://github.com/fmtlib/fmt/pull/223>`_):
|
||
|
||
.. code:: c++
|
||
|
||
fmt::print("{:p}", "test"); // prints pointer value
|
||
|
||
Thanks to `@LarsGullik <https://github.com/LarsGullik>`_.
|
||
|
||
* [Breaking] ``fmt::printf`` and ``fmt::sprintf`` now print null pointers as ``(nil)``
|
||
and null strings as ``(null)`` for consistency with glibc
|
||
(`#226 <https://github.com/fmtlib/fmt/pull/226>`_).
|
||
Thanks to `@LarsGullik <https://github.com/LarsGullik>`_.
|
||
|
||
* [Breaking] ``fmt::(s)printf`` now supports formatting of objects of user-defined types
|
||
that provide an overloaded ``std::ostream`` insertion operator (``operator<<``)
|
||
(`#201 <https://github.com/fmtlib/fmt/issues/201>`_):
|
||
|
||
.. code:: c++
|
||
|
||
fmt::printf("The date is %s", Date(2012, 12, 9));
|
||
|
||
* [Breaking] The ``Buffer`` template is now part of the public API and can be used
|
||
to implement custom memory buffers
|
||
(`#140 <https://github.com/fmtlib/fmt/issues/140>`_).
|
||
Thanks to `@polyvertex (Jean-Charles Lefebvre) <https://github.com/polyvertex>`_.
|
||
|
||

|
||
`std::experimental::basic_string_view
|
||
<http://en.cppreference.com/w/cpp/experimental/basic_string_view>`_
|
||
(`#100 <https://github.com/fmtlib/fmt/issues/100>`_,
|
||
`#159 <https://github.com/fmtlib/fmt/issues/159>`_,
|
||
`#183 <https://github.com/fmtlib/fmt/issues/183>`_):
|
||
|
||
- Comparison operators now compare string content, not pointers
|
||
- ``BasicStringRef::c_str`` replaced by ``BasicStringRef::data``
|
||
- ``BasicStringRef`` is no longer assumed to be null-terminated
|
||
|
||
References to null-terminated strings are now represented by a new class,
|
||
``BasicCStringRef``.
|
||
|
||
* Dependency on pthreads introduced by Google Test is now optional
|
||
(`#185 <https://github.com/fmtlib/fmt/issues/185>`_).
|
||
|

|
||
generation of ``doc``, ``install`` and ``test`` targets respectively, on by default
|
||
(`#197 <https://github.com/fmtlib/fmt/issues/197>`_,
|
||
`#198 <https://github.com/fmtlib/fmt/issues/198>`_,
|

(`#171 <https://github.com/fmtlib/fmt/issues/171>`_).
|
||
Thanks to `@alfps (Alf P. Steinbach) <https://github.com/alfps>`_.
|
||
|
||
* [Breaking] ``windows.h`` is now included with ``NOMINMAX`` unless
|
||
``FMT_WIN_MINMAX`` is defined. This is done to prevent breaking code using
|
||
``std::min`` and ``std::max`` and only affects the header-only configuration
|
||
(`#152 <https://github.com/fmtlib/fmt/issues/152>`_,

`#208 <https://github.com/fmtlib/fmt/pull/208>`_).
|
||
Thanks to `@JodiTheTigger <https://github.com/JodiTheTigger>`_.

Optimization
|
||
~~~~~~~~~~~~
|
||

|
||
(`#92 <https://github.com/fmtlib/fmt/issues/92>`_,
|
||
`#230 <https://github.com/fmtlib/fmt/pull/230>`_).
|

|
||
(`#115 <https://github.com/fmtlib/fmt/pull/115>`_,
|
||
`#116 <https://github.com/fmtlib/fmt/pull/116>`_,

|
||
|
||
You can now install C++ Format with ``make install`` command.
|
||
|
||
* Improved `Biicode <http://www.biicode.com/>`_ support
|
||
(`#98 <https://github.com/fmtlib/fmt/pull/98>`_ and
|
||
`#104 <https://github.com/fmtlib/fmt/pull/104>`_). Thanks to
|
||
`@MariadeAnton <https://github.com/MariadeAnton>`_ and
|
||
`@franramirez688 <https://github.com/franramirez688>`_.
|
||
|
||
* Improved support for building with `Android NDK
|
||
<https://developer.android.com/tools/sdk/ndk/index.html>`_
|
||
(`#107 <https://github.com/fmtlib/fmt/pull/107>`_).
|
||
Thanks to `@newnon <https://github.com/newnon>`_.
|
||
|
||
The `android-ndk-example <https://github.com/fmtlib/android-ndk-example>`_

repository provides and example of using C++ Format with Android NDK:
|
||
|
||

master/screenshot.png
|
||
|
||
* Improved documentation of ``SystemError`` and ``WindowsError``
|
||
(`#54 <https://github.com/fmtlib/fmt/issues/54>`_).
|
||
|
||
* Various code improvements
|
||
(`#110 <https://github.com/fmtlib/fmt/pull/110>`_,
|
||
`#111 <https://github.com/fmtlib/fmt/pull/111>`_
|
||
`#112 <https://github.com/fmtlib/fmt/pull/112>`_).
|
||
Thanks to `@CarterLi <https://github.com/CarterLi>`_.
|
||
|
||
* Improved compile-time errors when formatting wide into narrow strings
|
||
(`#117 <https://github.com/fmtlib/fmt/issues/117>`_).
|
||
|
||
* Fixed ``BasicWriter::write`` without formatting arguments when C++11 support
|
||
is disabled (`#109 <https://github.com/fmtlib/fmt/issues/109>`_).
|
||
|
||
* Fixed header-only build on OS X with GCC 4.9
|
||
(`#124 <https://github.com/fmtlib/fmt/issues/124>`_).
|
||
|
||
* Fixed packaging issues (`#94 <https://github.com/fmtlib/fmt/issues/94>`_).

|
||
(`#103 <https://github.com/fmtlib/fmt/issues/103>`_).
|
||
|
||
1.0.0 - 2015-02-05
|
||
------------------
|
||
|
||
* Add support for a header-only configuration when ``FMT_HEADER_ONLY`` is
|
||
defined before including ``format.h``:
|
||
|
||
.. code:: c++
|
||
|
||
#define FMT_HEADER_ONLY
|
||
#include "format.h"
|
||
|
||
* Compute string length in the constructor of ``BasicStringRef``
|
||
instead of the ``size`` method
|
||
(`#79 <https://github.com/fmtlib/fmt/issues/79>`_).
|
||
This eliminates size computation for string literals on reasonable optimizing
|
||
compilers.
|
||
|
||
* Fix formatting of types with overloaded ``operator <<`` for ``std::wostream``
|
||
(`#86 <https://github.com/fmtlib/fmt/issues/86>`_):
|
||
|
||
.. code:: c++
|
||
|
||
fmt::format(L"The date is {0}", Date(2012, 12, 9));
|
||
|
||
* Fix linkage of tests on Arch Linux
|
||
(`#89 <https://github.com/fmtlib/fmt/issues/89>`_).
|
||
|
||
* Allow precision specifier for non-float arguments
|
||
(`#90 <https://github.com/fmtlib/fmt/issues/90>`_):
|
||
|
||
.. code:: c++
|
||
|
||
fmt::print("{:.3}\n", "Carpet"); // prints "Car"
|
||
|
||
* Fix build on Android NDK
|
||
(`#93 <https://github.com/fmtlib/fmt/issues/93>`_)
|
||
|
||
* Improvements to documentation build procedure.
|
||
|
||
* Remove ``FMT_SHARED`` CMake variable in favor of standard `BUILD_SHARED_LIBS
|
||
<http://www.cmake.org/cmake/help/v3.0/variable/BUILD_SHARED_LIBS.html>`_.
|
||
|
||
* Fix error handling in ``fmt::fprintf``.
|
||
|
||
* Fix a number of warnings.
|
||
|
||
0.12.0 - 2014-10-25
|
||
-------------------
|
||
|
||
* [Breaking] Improved separation between formatting and buffer management.
|
||
``Writer`` is now a base class that cannot be instantiated directly.
|
||
The new ``MemoryWriter`` class implements the default buffer management
|
||
with small allocations done on stack. So ``fmt::Writer`` should be replaced
|
||
with ``fmt::MemoryWriter`` in variable declarations.
|
||
|
||
Old code:
|
||
|
||
.. code:: c++
|
||
|
||
fmt::Writer w;
|
||
|
||
New code:
|
||
|
||
.. code:: c++
|
||
|
||
fmt::MemoryWriter w;
|
||
|
||
If you pass ``fmt::Writer`` by reference, you can continue to do so:
|
||
|
||
.. code:: c++
|
||
|
||
void f(fmt::Writer &w);
|
||
|
||
This doesn't affect the formatting API.
|
||
|
||
* Support for custom memory allocators
|
||
(`#69 <https://github.com/fmtlib/fmt/issues/69>`_)
|
||
|
||
* Formatting functions now accept `signed char` and `unsigned char` strings as
|
||
arguments (`#73 <https://github.com/fmtlib/fmt/issues/73>`_):
|
||
|
||
.. code:: c++
|
||
|
||
auto s = format("GLSL version: {}", glGetString(GL_VERSION));
|
||
|
||
* Reduced code bloat. According to the new `benchmark results
|
||
<https://github.com/fmtlib/fmt#compile-time-and-code-bloat>`_,
|
||
cppformat is close to ``printf`` and by the order of magnitude better than
|
||
Boost Format in terms of compiled code size.
|
||
|
||
* Improved appearance of the documentation on mobile by using the `Sphinx
|
||
Bootstrap theme <http://ryan-roemer.github.io/sphinx-bootstrap-theme/>`_:

0.11.0 - 2014-08-21
|
||
-------------------
|
||
|
||
* Safe printf implementation with a POSIX extension for positional arguments:
|
||
|
||
.. code:: c++
|
||
|
||
fmt::printf("Elapsed time: %.2f seconds", 1.23);
|
||
fmt::printf("%1$s, %3$d %2$s", weekday, month, day);
|
||
|
||
* Arguments of ``char`` type can now be formatted as integers
|
||
(Issue `#55 <https://github.com/fmtlib/fmt/issues/55>`_):
|
||
|
||
.. code:: c++
|
||
|
||
fmt::format("0x{0:02X}", 'a');
|
||
|
||
* Deprecated parts of the API removed.
|
||
|
||
* The library is now built and tested on MinGW with Appveyor in addition to
|
||
existing test platforms Linux/GCC, OS X/Clang, Windows/MSVC.
|
||
|
||
0.10.0 - 2014-07-01
|
||
-------------------
|
||
|
||
**Improved API**
|
||
|
||
* All formatting methods are now implemented as variadic functions instead
|
||
of using ``operator<<`` for feeding arbitrary arguments into a temporary
|
||
formatter object. This works both with C++11 where variadic templates are
|
||
used and with older standards where variadic functions are emulated by
|
||
providing lightweight wrapper functions defined with the ``FMT_VARIADIC``
|
||
macro. You can use this macro for defining your own portable variadic
|
||
functions:
|
||
|
||
.. code:: c++
|
||
|
||
void report_error(const char *format, const fmt::ArgList &args) {
|
||
fmt::print("Error: {}");
|
||
fmt::print(format, args);
|
||
}
|
||
FMT_VARIADIC(void, report_error, const char *)
|
||
|
||
report_error("file not found: {}", path);
|
||
|
||
Apart from a more natural syntax, this also improves performance as there
|
||
is no need to construct temporary formatter objects and control arguments'
|
||
lifetimes. Because the wrapper functions are very lightweight, this doesn't
|
||
cause code bloat even in pre-C++11 mode.
|
||
|
||
* Simplified common case of formatting an ``std::string``. Now it requires a
|
||
single function call:
|
||
|
||
.. code:: c++
|
||
|
||
std::string s = format("The answer is {}.", 42);
|
||
|
||
Previously it required 2 function calls:
|
||
|
||
.. code:: c++
|
||
|
||
std::string s = str(Format("The answer is {}.") << 42);
|
||
|
||
Instead of unsafe ``c_str`` function, ``fmt::Writer`` should be used directly
|
||
to bypass creation of ``std::string``:
|
||
|
||
.. code:: c++
|
||
|
||
fmt::Writer w;
|
||
w.write("The answer is {}.", 42);
|
||
w.c_str(); // returns a C string
|
||
|
||
This doesn't do dynamic memory allocation for small strings and is less error
|
||
prone as the lifetime of the string is the same as for ``std::string::c_str``
|
||
which is well understood (hopefully).
|
||
|
||
* Improved consistency in naming functions that are a part of the public API.
|
||
Now all public functions are lowercase following the standard library
|
||
conventions. Previously it was a combination of lowercase and
|
||
CapitalizedWords.
|
||
Issue `#50 <https://github.com/fmtlib/fmt/issues/50>`_.
|
||
|
||
* Old functions are marked as deprecated and will be removed in the next
|
||
release.
|
||
|
||
**Other Changes**
|
||
|
||
* Experimental support for printf format specifications (work in progress):
|
||
|
||
.. code:: c++
|
||
|
||
fmt::printf("The answer is %d.", 42);
|
||
std::string s = fmt::sprintf("Look, a %s!", "string");
|
||
|
||
* Support for hexadecimal floating point format specifiers ``a`` and ``A``:
|
||
|
||
.. code:: c++
|
||
|
||
print("{:a}", -42.0); // Prints -0x1.5p+5
|
||
print("{:A}", -42.0); // Prints -0X1.5P+5
|
||
|
||
* CMake option ``FMT_SHARED`` that specifies whether to build format as a
|
||
shared library (off by default).
|
||
|
||
0.9.0 - 2014-05-13
|
||
------------------
|
||
|
||
* More efficient implementation of variadic formatting functions.
|
||
|
||
* ``Writer::Format`` now has a variadic overload:
|
||
|
||
.. code:: c++
|
||
|
||
Writer out;
|
||
out.Format("Look, I'm {}!", "variadic");
|
||
|
||
* For efficiency and consistency with other overloads, variadic overload of
|
||
the ``Format`` function now returns ``Writer`` instead of ``std::string``.
|
||
Use the ``str`` function to convert it to ``std::string``:
|
||
|
||
.. code:: c++
|
||
|
||
std::string s = str(Format("Look, I'm {}!", "variadic"));
|
||
|
||
* Replaced formatter actions with output sinks: ``NoAction`` -> ``NullSink``,
|
||
``Write`` -> ``FileSink``, ``ColorWriter`` -> ``ANSITerminalSink``.
|
||
This improves naming consistency and shouldn't affect client code unless
|
||
these classes are used directly which should be rarely needed.
|
||
|
||
* Added ``ThrowSystemError`` function that formats a message and throws
|
||
``SystemError`` containing the formatted message and system-specific error
|
||
description. For example, the following code
|
||
|
||
.. code:: c++
|
||
|
||
FILE *f = fopen(filename, "r");
|
||
if (!f)
|
||
ThrowSystemError(errno, "Failed to open file '{}'") << filename;
|
||
|
||
will throw ``SystemError`` exception with description
|
||
"Failed to open file '<filename>': No such file or directory" if file
|
||
doesn't exist.
|
||
|
||
* Support for AppVeyor continuous integration platform.
|
||
|
||
* ``Format`` now throws ``SystemError`` in case of I/O errors.
|
||
|
||
* Improve test infrastructure. Print functions are now tested by redirecting
|
||
the output to a pipe.

||

||
0.8.0 - 2014-04-14
