6.1.0 - TBD
-----------
* {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);
}
2019-11-28 15:43:22 +00:00
prints ``3.141592653589793``.
2019-11-28 00:15:42 +00:00
2019-11-28 15:43:22 +00:00
* Made the fast binary to decimal floating-point formatter the default and
2019-11-28 00:15:42 +00:00
sligthly improved its performance. {fmt} is now 15x faster than libc++'s
``std::ostringstream``, 11x faster than ``printf`` and 10% faster than
2019-11-28 15:43:22 +00:00
double-conversion on dtoa-benchmark:

2019-11-28 15:43:22 +00:00
* {fmt} no longer converts ``float`` arguments to ``double``. In particular this
improves the default (shortest) representation of ``float``s and makes
``fmt::format`` consistent with ``std::format`` specs
(`#1336 <https://github.com/fmtlib/fmt/issues/1336>`_,
`#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>`_.
2019-11-28 00:15:42 +00:00
* Added support for ``int128_t``
(`#1287 <https://github.com/fmtlib/fmt/pull/1287>`_):
.. code:: c++
fmt::print("{}", std::numeric_limits<__int128_t>::max());
2019-11-28 15:43:22 +00:00
prints ``170141183460469231731687303715884105727``.
2019-11-28 00:15:42 +00:00
Thanks `@denizevrenci (Deniz Evrenci) <https://github.com/denizevrenci>`_.
2019-11-28 15:43:22 +00:00
* 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>`_.
2019-11-28 00:15:42 +00:00
2019-11-28 15:43:22 +00:00
* 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>`_):
2019-11-28 00:15:42 +00:00
2019-11-28 15:43:22 +00:00
.. 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 "0o0" to "0":
.. code:: c++
fmt::print("{:#o}", 0);
prints ``0``.
2019-11-28 00:15:42 +00:00
* 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>`_.
* 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>`_.
2019-11-28 15:43:22 +00:00
* {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>`__
`package <https://github.com/conda-forge/fmt-feedstock>`__
(`#1410 <https://github.com/fmtlib/fmt/pull/1410>`_)::
conda install -c conda-forge fmt
Thanks `@tdegeus (Tom de Geus) <https://github.com/tdegeus>`_.
* Added a CUDA test (`#1285 <https://github.com/fmtlib/fmt/pull/1285>`_,
`#1317 <https://github.com/fmtlib/fmt/pull/1317>`_).
Thanks `@luncliff (Park DongHa) <https://github.com/luncliff>`_ and
`@risa2000 <https://github.com/risa2000>`_.
2019-11-28 00:15:42 +00:00

6.0.0 - 2019-08-26
------------------
2019-07-12 16:54:02 +00:00
2019-08-24 13:32:47 +00:00
* 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.
2019-08-10 17:01:23 +00:00
* Floating-point formatting is now locale-independent by default:
2019-07-12 23:21:13 +00:00
.. 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".
2019-08-04 16:20:49 +00:00
* Added an experimental Grisu floating-point formatting algorithm
2019-08-10 14:59:33 +00:00
implementation (disabled by default). To enable it compile with the
2019-08-10 16:56:13 +00:00
``FMT_USE_GRISU`` macro defined to 1:
2019-08-04 16:20:49 +00:00
.. code:: c++
#define FMT_USE_GRISU 1
#include <fmt/format.h>
auto s = fmt::format("{}", 4.2); // formats 4.2 using Grisu
2019-08-04 17:38:33 +00:00
With Grisu enabled, {fmt} is 13x faster than ``std::ostringstream`` (libc++)
2019-08-10 14:59:33 +00:00
and 10x faster than ``sprintf`` on `dtoa-benchmark
<https://github.com/fmtlib/dtoa-benchmark>`_ (`full results
<https://fmt.dev/unknown_mac64_clang10.0.html>`_):

54883977-9fe8c000-4e28-11e9-8bde-272d122e7c52.jpg
2019-08-24 13:32:47 +00:00
* Separated formatting and parsing contexts for consistency with
2019-08-24 13:34:19 +00:00
`C++20 std::format <http://eel.is/c++draft/format>`_, removing the
2019-08-24 13:32:47 +00:00
undocumented ``basic_format_context::parse_context()`` function.
2019-08-10 16:56:13 +00:00
* Added `oss-fuzz <https://github.com/google/oss-fuzz>`_ support
2019-08-10 14:59:33 +00:00
(`#1199 <https://github.com/fmtlib/fmt/pull/1199>`_).
2019-08-10 17:01:23 +00:00
Thanks `@pauldreik (Paul Dreik) <https://github.com/pauldreik>`_.
2019-08-04 16:20:49 +00:00
2019-08-04 14:28:48 +00:00
* ``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
2019-08-10 14:59:33 +00:00
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>`_):
2019-07-25 15:44:40 +00:00
.. code:: c++
2019-07-25 16:59:59 +00:00
#include <fmt/compile.h>
auto f = fmt::compile<int>("{}");
2019-08-04 14:28:48 +00:00
std::string s = fmt::format(f, 42); // can be called multiple times to format
// different values
2019-07-25 16:59:59 +00:00
// s == "42"
2019-07-25 15:44:40 +00:00
2019-08-04 14:28:48 +00:00
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>`_.
2019-08-04 16:20:49 +00:00
* Added the ``%`` format specifier that formats floating-point values as
percentages (`#1060 <https://github.com/fmtlib/fmt/pull/1060>`_,
2019-08-10 16:56:13 +00:00
`#1069 <https://github.com/fmtlib/fmt/pull/1069>`_,
2019-08-04 16:20:49 +00:00
`#1071 <https://github.com/fmtlib/fmt/pull/1071>`_):
.. code:: c++
auto s = fmt::format("{:.1%}", 0.42); // s == "42.0%"
2019-08-10 17:01:23 +00:00
Thanks `@gawain-bolton (Gawain Bolton) <https://github.com/gawain-bolton>`_.
2019-08-04 16:20:49 +00:00
2019-08-04 14:28:48 +00:00
* 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>`_):
2019-08-04 16:20:49 +00:00
.. code:: c++
auto value = fmt::format("{:%Q}", 42s); // value == "42"
auto unit = fmt::format("{:%q}", 42s); // unit == "s"
2019-08-04 14:28:48 +00:00
Thanks `@DanielaE (Daniela Engert) <https://github.com/DanielaE>`_.
2019-07-25 15:44:40 +00:00
* Fixed handling of dynamic width in chrono formatter:
2019-07-25 16:59:59 +00:00
.. code:: c++
2019-07-25 15:44:40 +00:00
2019-07-25 16:59:59 +00:00
auto s = fmt::format("{0:{1}%H:%M:%S}", std::chrono::seconds(12345), 12);
// ^ width argument index ^ width
// s == "03:25:45 "
2019-07-25 15:44:40 +00:00
Thanks Howard Hinnant.
2019-08-04 16:20:49 +00:00
* Removed deprecated ``fmt/time.h``. Use ``fmt/chrono.h`` instead.
2019-07-25 16:59:59 +00:00
* Added ``fmt::format`` and ``fmt::vformat`` overloads that take ``text_style``
2019-07-25 15:44:40 +00:00
(`#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>`_.
2019-08-10 14:59:33 +00:00
* Removed the deprecated color API (``print_colored``). Use the new API, namely
``print`` overloads that take ``text_style`` instead.
2019-08-04 17:38:33 +00:00
* Made ``std::unique_ptr`` and ``std::shared_ptr`` formattable as pointers via
2019-08-10 16:25:16 +00:00
``fmt::ptr`` (`#1121 <https://github.com/fmtlib/fmt/pull/1121>`_):
2019-08-04 17:38:33 +00:00
.. code:: c++
std::unique_ptr<int> p = ...;
fmt::print("{}", fmt::ptr(p)); // prints p as a pointer
2019-08-10 16:25:16 +00:00
Thanks `@sighingnow (Tao He) <https://github.com/sighingnow>`_.
2019-08-04 17:38:33 +00:00
* 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>`_.
2019-08-04 14:28:48 +00:00
* 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>`_.
2019-08-10 14:59:33 +00:00
* Modernized the codebase using more C++11 features and removing workarounds.
Most importantly, ``buffer_context`` is now an alias template, so
2019-08-24 13:46:43 +00:00
use ``buffer_context<T>`` instead of ``buffer_context<T>::type``.
2019-09-13 01:20:48 +00:00
These features require GCC 4.8 or later.
2019-08-10 14:59:33 +00:00
* ``formatter`` specializations now always take precedence over implicit
conversions to ``int`` and the undocumented ``convert_to_int`` trait
is now deprecated.
2019-08-04 16:20:49 +00:00
* Moved the undocumented ``basic_writer``, ``writer``, and ``wwriter`` types
to the ``internal`` namespace.
2019-08-10 14:59:33 +00:00
* 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.
2019-08-04 16:20:49 +00:00
* Moved SFINAE to template parameters to reduce symbol sizes.
2019-08-10 16:25:16 +00:00
* 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>`_).
2019-08-10 14:59:33 +00:00
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>`_.
2019-08-04 17:38:33 +00:00
* Added support for exotic platforms without ``uintptr_t`` such as IBM i
2019-08-10 14:59:33 +00:00
(AS/400) which has 128-bit pointers and only 64-bit integers

5.3.0 - 2018-12-28
------------------
2018-12-24 17:37:52 +00:00
2018-12-24 19:47:06 +00:00
* 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:

Any object of type ``S`` that has an overloaded ``to_string_view(const S&)``
2018-12-24 19:47:06 +00:00
returning ``fmt::string_view`` can be used as a format string:
2018-12-24 17:37:52 +00:00
.. code:: c++
namespace my_ns {
2018-12-24 18:02:41 +00:00
inline string_view to_string_view(const my_string& s) {
return {s.data(), s.length()};
2018-12-24 17:37:52 +00:00
}
}
2018-12-24 18:02:41 +00:00

* 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>`_.
2018-12-24 18:56:13 +00:00
* 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

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>`_.

5.2.0 - 2018-09-13
------------------
2018-08-11 14:12:52 +00:00
2018-09-13 00:34:16 +00:00
* Optimized format string parsing and argument processing which resulted in up
to 5x speed up on long format strings and significant performance boost on
2018-09-13 02:00:26 +00:00
various benchmarks. For example, version 5.2 is 2.22x faster than 5.1 on
2018-09-13 00:34:16 +00:00
decimal integer formatting with ``format_to`` (macOS, clang-902.0.39.2):

================== ======= =======
2018-09-12 17:39:08 +00:00
* 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);
2018-09-12 17:39:08 +00:00
* Added compile-time format string checks to ``format_to`` overload that takes
``fmt::memory_buffer`` (`#783 <https://github.com/fmtlib/fmt/issues/783>`_):
2018-09-12 17:39:08 +00:00
.. 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.
2018-09-12 17:39:08 +00:00
* 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.
2018-08-11 14:12:52 +00:00
* Added support for dynamic argument lists
(`#814 <https://github.com/fmtlib/fmt/issues/814>`_,
2018-09-12 17:39:08 +00:00
`#819 <https://github.com/fmtlib/fmt/pull/819>`_).

Thanks `@MikePopoloski (Michael Popoloski)
<https://github.com/MikePopoloski>`_.

making locale dependency optional
(`#839 <https://github.com/fmtlib/fmt/pull/839>`_).
Thanks `@teajay-fr (Thomas Benard) <https://github.com/teajay-fr>`_.
2018-09-12 17:39:08 +00:00

``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
(`#807 <https://github.com/fmtlib/fmt/issues/807>`_):
.. code:: c++
// This works on compilers with constexpr support.
static const std::string answer = fmt::format("{}", 42);

5.1.0 - 2018-07-05
------------------
2018-07-04 23:00:06 +00:00
* 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.

* Added quotes to strings in ranges and tuples
(`#766 <https://github.com/fmtlib/fmt/pull/766>`_).
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
(`#795 <https://github.com/fmtlib/fmt/issues/795>`_).
* Fixed incorrect call to on_align in ``'{:}='``
(`#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
(`#754 <https://github.com/fmtlib/fmt/issues/754>`_).
* Fixed handling of compile-time strings when including ``fmt/ostream.h``.
(`#768 <https://github.com/fmtlib/fmt/issues/768>`_).

5.0.0 - 2018-05-21
------------------
2018-05-12 16:10:11 +00:00
2018-05-13 19:42:55 +00:00
* 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
2018-05-13 15:53:16 +00:00
<https://github.com/fmtlib/fmt/releases/tag/4.1.0>`_ which continues to be
2018-05-13 19:42:55 +00:00
maintained and works with C++98 compilers.
2018-05-12 16:10:11 +00:00
2018-05-13 15:53:16 +00:00
* 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>`_.
2018-05-12 16:10:11 +00:00
2018-05-19 17:31:49 +00:00
* Implemented ``constexpr`` parsing of format strings and `compile-time format
string checks
2019-05-17 22:42:00 +00:00
<https://fmt.dev/dev/api.html#compile-time-format-string-checks>`_. For
2018-05-19 17:31:49 +00:00
example
.. code:: c++
#include <fmt/format.h>
2018-05-20 23:00:39 +00:00
2018-05-19 17:31:49 +00:00
std::string s = format(fmt("{:d}"), "foo");
2018-05-19 18:46:55 +00:00
gives a compile-time error because ``d`` is an invalid specifier for strings
2018-05-22 03:38:07 +00:00
(`godbolt <https://godbolt.org/g/rnCy9Q>`__)::
2018-05-19 17:31:49 +00:00
...
<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");
2018-05-13 19:42:55 +00:00
2018-05-19 18:46:55 +00:00
Compile-time checks require relaxed ``constexpr`` (C++14 feature) support. If
the latter is not available, checks will be performed at runtime.
2018-05-13 19:42:55 +00:00
* Separated format string parsing and formatting in the extension API to enable
compile-time format string processing. For example
2018-05-13 15:53:16 +00:00
.. code:: c++
2018-05-22 03:27:58 +00:00
struct Answer {};
2018-05-13 15:53:16 +00:00
namespace fmt {
template <>

2018-05-19 18:46:55 +00:00
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')
2018-05-16 15:19:26 +00:00

3.0.0 - 2016-05-07
------------------
2016-05-04 15:49:29 +00:00
* 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"
2016-05-05 15:20:12 +00:00
Including ``format.h`` from the ``cppformat`` directory is deprecated
2016-05-04 15:49:29 +00:00
but works via a proxy header which will be removed in the next major version.
2016-05-07 15:59:19 +00:00
2019-05-17 22:42:00 +00:00
The documentation is now available at https://fmt.dev.
2016-05-04 15:49:29 +00:00
2016-05-07 14:50:56 +00:00
* Added support for `strftime <http://en.cppreference.com/w/cpp/chrono/c/strftime>`_-like
2019-05-17 22:42:00 +00:00
`date and time formatting <https://fmt.dev/3.0.0/api.html#date-and-time-formatting>`_
2016-05-07 14:50:56 +00:00
(`#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));
2016-05-07 15:50:51 +00:00
* ``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"
2016-05-07 14:50:56 +00:00
* Added support for `custom argument formatters
2019-05-17 22:42:00 +00:00
<https://fmt.dev/3.0.0/api.html#argument-formatters>`_
2016-05-07 14:50:56 +00:00
(`#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
2016-05-07 14:50:56 +00:00
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>`_).
2016-05-04 15:49:29 +00:00
* Fixed detection of user-defined literal support on Intel C++ compiler

2015-03-05 16:04:27 +00:00
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
2016-04-28 13:45:50 +00:00
(`#79 <https://github.com/fmtlib/fmt/issues/79>`_).

2015-03-05 16:04:27 +00:00
* 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.
2015-03-05 15:26:44 +00:00
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
2016-04-28 13:45:50 +00:00
(`#69 <https://github.com/fmtlib/fmt/issues/69>`_)
2015-03-05 15:26:44 +00:00
* Formatting functions now accept `signed char` and `unsigned char` strings as
2016-04-28 13:45:50 +00:00
arguments (`#73 <https://github.com/fmtlib/fmt/issues/73>`_):
2015-03-05 15:26:44 +00:00
.. code:: c++
auto s = format("GLSL version: {}", glGetString(GL_VERSION));
* Reduced code bloat. According to the new `benchmark results
2016-04-28 13:45:50 +00:00
<https://github.com/fmtlib/fmt#compile-time-and-code-bloat>`_,
2015-03-05 15:26:44 +00:00
cppformat is close to ``printf`` and by the order of magnitude better than
Boost Format in terms of compiled code size.
2015-03-05 15:31:27 +00:00
* 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);
2015-03-05 03:02:59 +00:00
* Arguments of ``char`` type can now be formatted as integers
2016-04-28 13:45:50 +00:00
(Issue `#55 <https://github.com/fmtlib/fmt/issues/55>`_):
2015-03-05 02:49:23 +00:00
.. 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.
2015-03-05 02:30:00 +00:00
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'
2016-05-01 10:29:21 +00:00
lifetimes. Because the wrapper functions are very lightweight, this doesn't
2015-03-05 02:30:00 +00:00
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
2015-03-05 03:02:59 +00:00
CapitalizedWords.
2016-04-28 13:45:50 +00:00
Issue `#50 <https://github.com/fmtlib/fmt/issues/50>`_.
2015-03-05 02:30:00 +00:00
* 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).
2015-03-05 02:10:08 +00:00
0.9.0 - 2014-05-13
------------------
* More efficient implementation of variadic formatting functions.
2015-03-05 02:16:26 +00:00
* ``Writer::Format`` now has a variadic overload:
.. code:: c++
2015-03-05 02:10:08 +00:00
Writer out;
out.Format("Look, I'm {}!", "variadic");
* For efficiency and consistency with other overloads, variadic overload of
2015-03-05 02:16:26 +00:00
the ``Format`` function now returns ``Writer`` instead of ``std::string``.
Use the ``str`` function to convert it to ``std::string``:
.. code:: c++
2015-03-05 02:10:08 +00:00
std::string s = str(Format("Look, I'm {}!", "variadic"));
2015-03-05 02:16:26 +00:00
* 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
2015-03-05 02:10:08 +00:00
2015-03-05 02:16:26 +00:00
.. code:: c++
2015-03-05 02:10:08 +00:00
FILE *f = fopen(filename, "r");
if (!f)
ThrowSystemError(errno, "Failed to open file '{}'") << filename;
2015-03-05 02:16:26 +00:00
will throw ``SystemError`` exception with description
