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
`conda-forge <https://conda-forge.org>`__

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>

struct S {};
std::ostream& operator<<(std::ostream& os, S) {

}
* 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 the ``%`` 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>`_).
* Various build improvements
(`#1039 <https://github.com/fmtlib/fmt/pull/1039>`_,

Folly Format folly::format 2.23
================= ============= ===========
{fmt} is the fastest of the benchmarked methods, ~35% faster than ``printf``.
The above results were generated by building ``tinyformat_test.cpp`` on macOS
10.14.6 with ``clang++ -O3 -DSPEED_TEST -DHAVE_FORMAT``, and taking the best of
three runs. In the test, the format string ``"%0.10f:%04d:%+g:%s:%p:%c:%%\n"``
or equivalent is filled 2,000,000 times with output sent to ``/dev/null``; for
further details refer to the `source
<https://github.com/fmtlib/format-benchmark/blob/master/tinyformat_test.cpp>`_.
{fmt} is 10x faster than ``std::ostringstream`` and ``sprintf`` on floating-point
formatting (`dtoa-benchmark <https://github.com/fmtlib/dtoa-benchmark>`_)
and as fast as `double-conversion <https://github.com/google/double-conversion>`_:

Compile time and code bloat
~~~~~~~~~~~~~~~~~~~~~~~~~~~
The script `bloat-test.py
<https://github.com/fmtlib/format-benchmark/blob/master/bloat-test.py>`_
from `format-benchmark <https://github.com/fmtlib/format-benchmark>`_
tests compile time and code bloat for nontrivial projects.
It generates 100 translation units and uses ``printf()`` or its alternative
five times in each to simulate a medium sized project. The resulting
executable size and compile time (Apple LLVM version 8.1.0 (clang-802.0.42),
macOS Sierra, best of three) is shown in the following tables.

{fmt} 19.0 37 34
Boost Format 91.9 226 203
Folly Format 115.7 101 88
============= =============== ==================== ==================
As you can see, {fmt} has 60% less overhead in terms of resulting binary code
size compared to iostreams and comes pretty close to ``printf``. Boost Format
and Folly Format have the largest overheads.
``printf+string`` is the same as ``printf`` but with extra ``<string>``
include to measure the overhead of the latter.

Boost Format 54.1 365 303
Folly Format 79.9 445 430
============= =============== ==================== ==================
``libc``, ``lib(std)c++`` and ``libfmt`` are all linked as shared libraries to
compare formatting function overhead only. Boost Format is a
header-only library so it doesn't provide any linkage options.

SafeFormat is a formatting library which uses printf-like format strings

This library supports printf-like format strings and is very small and

it in C++98 is somewhat difficult. Also its performance and code compactness
are limited by IOStreams.

Speed tests
~~~~~~~~~~~
The following speed tests results were generated by building
``tinyformat_test.cpp`` on Ubuntu GNU/Linux 14.04.1 with
``g++-4.8.2 -O3 -DSPEED_TEST -DHAVE_FORMAT``, and taking the best of three
runs. In the test, the format string ``"%0.10f:%04d:%+g:%s:%p:%c:%%\n"`` or

Tinyformat is quite good coming close to IOStreams. Unfortunately tinyformat
cannot be faster than the IOStreams because it uses them internally.
Performance of fmt is close to that of printf, being `faster than printf on integer
