10.1.0 - 2023-08-12
|
||||
-------------------
|
||||
|
||||
* Optimized format string compilation resulting in up to 40% speed up in
|
||||
compiled ``format_to`` and ~4x speed up in compiled ``format_to_n`` on a

`#3570 <https://github.com/fmtlib/fmt/pull/3570>`_).
|
||||
For example (`godbolt <https://godbolt.org/z/zYb79Pvn8>`__):
|
||||
|

.. code:: c++
|
||||
|
||||
#include <vector>
|

`@felix642 (Félix-Antoine Constantin) <https://github.com/felix642>`_.
|
||||
|
||||
* Fixed an ambiguous formatter specialization for containers that look like
|
||||
container adaptors such as ``boost::flat_set``
|
||||
(`#3556 <https://github.com/fmtlib/fmt/issues/3556>`_,
|
||||
`#3561 <https://github.com/fmtlib/fmt/pull/3561>`_).

||||
Thanks `@5chmidti <https://github.com/5chmidti>`_.
|
||||
|
||||
* Fixed compilation when formatting durations not convertible from
|
||||
``std::chrono::seconds`` (`#3430 <https://github.com/fmtlib/fmt/pull/3430>`_).
|
||||
Thanks `@patlkli (Patrick Geltinger) <https://github.com/patlkli>`_.
|
||||
|
||||
* Made the ``formatter`` specialization for ``char*`` const-correct
|
||||
(`#3432 <https://github.com/fmtlib/fmt/pull/3432>`_).
|
||||
Thanks `@timsong-cpp <https://github.com/timsong-cpp>`_.
|
||||
|
||||
* Made ``{}`` and ``{:}`` handled consistently during compile-time checks
|
||||
(`#3526 <https://github.com/fmtlib/fmt/issues/3526>`_).
|
||||
|
||||
* Disallowed passing temporaries to ``make_format_args`` to improve API safety
|
||||
by preventing dangling references.
|
||||
|
||||
* Improved the compile-time error for unformattable types
|
||||
(`#3478 <https://github.com/fmtlib/fmt/pull/3478>`_).

`#3450 <https://github.com/fmtlib/fmt/pull/3450>`_).
|
||||
Thanks `@florimond-collette (Florimond Collette)
|
||||
<https://github.com/florimond-collette>`_.

* Fixed handling of precision for ``long double`` larger than 64 bits.
|
||||
(`#3539 <https://github.com/fmtlib/fmt/issues/3539>`_,
|
||||
`#3564 <https://github.com/fmtlib/fmt/issues/3564>`_).
|
||||
|

10.0.0 - 2023-05-09
|
||||
-------------------
|
||||
|
||||
* Replaced Grisu with a new floating-point formatting algorithm for given
|
||||
precision (`#3262 <https://github.com/fmtlib/fmt/issues/3262>`_,
|
||||
`#2750 <https://github.com/fmtlib/fmt/issues/2750>`_,
|
||||
`#3269 <https://github.com/fmtlib/fmt/pull/3269>`_,
|
||||
`#3276 <https://github.com/fmtlib/fmt/pull/3276>`_).
|
||||
The new algorithm is based on Dragonbox already used for the
|
||||
shortest representation and gives substantial performance improvement:

||||

||||

|
||||
|
||||
* Red: new algorithm
|
||||
* Green: new algorithm with ``FMT_USE_FULL_CACHE_DRAGONBOX`` defined to 1
|
||||
* Blue: old algorithm
|
||||
|
||||
Thanks `@jk-jeon (Junekey Jeon) <https://github.com/jk-jeon>`_.
|
||||
|
||||
* Replaced ``snprintf``-based hex float formatter with an internal
|
||||
implementation (`#3179 <https://github.com/fmtlib/fmt/pull/3179>`_,
|
||||
`#3203 <https://github.com/fmtlib/fmt/pull/3203>`_).
|
||||
This removes the last usage of ``s(n)printf`` in {fmt}.
|
||||
Thanks `@phprus (Vladislav Shchapov) <https://github.com/phprus>`_.
|
||||
|
||||
* Fixed alignment of floating-point numbers with localization
|
||||
(`#3263 <https://github.com/fmtlib/fmt/issues/3263>`_,
|
||||
`#3272 <https://github.com/fmtlib/fmt/pull/3272>`_).
|
||||
Thanks `@ShawnZhong (Shawn Zhong) <https://github.com/ShawnZhong>`_.
|
||||
|
||||
* Made handling of ``#`` consistent with ``std::format``.
|
||||
|
||||
* Improved C++20 module support
|
||||
(`#3134 <https://github.com/fmtlib/fmt/pull/3134>`_,
|
||||
`#3254 <https://github.com/fmtlib/fmt/pull/3254>`_,

||||
`#3387 <https://github.com/fmtlib/fmt/pull/3387>`_,
|
||||
`#3388 <https://github.com/fmtlib/fmt/pull/3388>`_,
|
||||
`#3392 <https://github.com/fmtlib/fmt/pull/3392>`_,
|
||||
`#3397 <https://github.com/fmtlib/fmt/pull/3397>`_,
|
||||
`#3399 <https://github.com/fmtlib/fmt/pull/3399>`_,
|
||||
`#3400 <https://github.com/fmtlib/fmt/pull/3400>`_).
|
||||
Thanks `@laitingsheng (Tinson Lai) <https://github.com/laitingsheng>`_,
|
||||
`@Orvid (Orvid King) <https://github.com/Orvid>`_,
|
||||
`@DanielaE (Daniela Engert) <https://github.com/DanielaE>`_.
|
||||
Switched to the `modules CMake library <https://github.com/vitaut/modules>`_
|
||||
which allows building {fmt} as a C++20 module with clang::
|
||||
|
||||
CXX=clang++ cmake -DFMT_MODULE=ON .
|
||||
make
|
||||
|
||||
* Made ``format_as`` work with any user-defined type and not just enums.
|
||||
For example (`godbolt <https://godbolt.org/z/b7rqhq5Kh>`__):
|
||||
|
||||
.. code:: c++
|
||||
|
||||
#include <fmt/format.h>
|
||||
|
||||
struct floaty_mc_floatface {
|
||||
double value;
|
||||
};
|
||||
|
||||
auto format_as(floaty_mc_floatface f) { return f.value; }
|
||||
|
||||
int main() {
|
||||
fmt::print("{:8}\n", floaty_mc_floatface{0.42}); // prints " 0.42"
|
||||
}
|
||||
|
||||
* Removed deprecated implicit conversions for enums and conversions to primitive
|
||||
types for compatibility with ``std::format`` and to prevent potential ODR
|
||||
violations. Use ``format_as`` instead.
|
||||
|
||||
* Added support for fill, align and width to the time point formatter
|
||||
(`#3237 <https://github.com/fmtlib/fmt/issues/3237>`_,
|
||||
`#3260 <https://github.com/fmtlib/fmt/pull/3260>`_,
|
||||

||||

||||
|
||||
.. code:: c++
|
||||
|
||||
#include <fmt/chrono.h>
|
||||
|
||||
int main() {
|
||||
// prints " 2023"
|
||||
fmt::print("{:>8%Y}\n", std::chrono::system_clock::now());
|
||||
}
|
||||
|
||||
Thanks `@ShawnZhong (Shawn Zhong) <https://github.com/ShawnZhong>`_.

`#3349 <https://github.com/fmtlib/fmt/pull/3349>`_).
|

||||
|
||||
.. code:: c++
|
||||
|
||||
#include <fmt/chrono.h>
|
||||
|
||||
int main() {
|

// prints 01.234567

`#3214 <https://github.com/fmtlib/fmt/pull/3214>`_).
|
||||
Thanks `@rbrich (Radek Brich) <https://github.com/rbrich>`_.
