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
(`#801 <https://github.com/fmtlib/fmt/issues/801>`_,
`#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
(`#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);
* Fixed various compiler warnings and errors
(`#804 <https://github.com/fmtlib/fmt/pull/804>`_,
`#809 <https://github.com/fmtlib/fmt/issues/809>`_,
`#811 <https://github.com/fmtlib/fmt/pull/811>`_,

`#852 <https://github.com/fmtlib/fmt/pull/852>`_,

Thanks `@henryiii (Henry Schreiner) <https://github.com/henryiii>`_,
`@medithe <https://github.com/medithe>`_, and
`@eliasdaler (Elias Daler) <https://github.com/eliasdaler>`_.
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>`_
`#767 <https://github.com/fmtlib/fmt/pull/767>`_).
thanks `@remotion (remo) <https://github.com/remotion>`_.
* 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>`_).
* Fixed various compiler warnings and errors
(`#742 <https://github.com/fmtlib/fmt/issues/742>`_,

`@0x8000-0000 (Sign Bit) <https://github.com/0x8000-0000>`_.
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
<http://fmtlib.net/dev/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
<http://fmtlib.net/dev/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
<http://fmtlib.net/dev/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
<http://fmtlib.net/dev/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 <http://fmtlib.net/dev/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
<http://fmtlib.net/dev/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
<http://fmtlib.net/dev/api.html#format-api>`_ with compile-time handling of
format strings.

**{fmt}** is an open-source formatting library for C++.
It can be used as a safe and fast alternative to (s)printf and IOStreams.
`Documentation <http://fmtlib.net/latest/>`_
`Documentation <http://fmtlib.net/latest/>`__
This is a development branch that implements the C++ standards proposal `P0645
Text Formatting <http://fmtlib.net/Text%20Formatting.html>`__.
Released versions are available from the `Releases page
<https://github.com/fmtlib/fmt/releases>`__.
Features
--------
* Two APIs: faster concatenation-based `write API
<http://fmtlib.net/latest/api.html#write-api>`_ and slower,
but still very fast, replacement-based `format API
<http://fmtlib.net/latest/api.html#format-api>`_ with positional arguments
for localization.
* Write API similar to the one used by IOStreams but stateless allowing
faster implementation.
* Format API with `format string syntax
<http://fmtlib.net/latest/syntax.html>`_
similar to the one used by `str.format
<https://docs.python.org/2/library/stdtypes.html#str.format>`_ in Python.
* Replacement-based `format API <http://fmtlib.net/dev/api.html>`_ with
positional arguments for localization.
* `Format string syntax <http://fmtlib.net/dev/syntax.html>`_ similar to the one
of `str.format <https://docs.python.org/2/library/stdtypes.html#str.format>`_
in Python.
* Safe `printf implementation
<http://fmtlib.net/latest/api.html#printf-formatting-functions>`_
including the POSIX extension for positional arguments.
<http://fmtlib.net/latest/api.html#printf-formatting-functions>`_ including
the POSIX extension for positional arguments.
* Support for user-defined types.
* High speed: performance of the format API is close to that of
glibc's `printf <http://en.cppreference.com/w/cpp/io/c/fprintf>`_
and better than the performance of IOStreams. See `Speed tests`_ and

`Fast integer to string conversion in C++
<http://zverovich.net/2013/09/07/integer-to-string-conversion-in-cplusplus.html>`_.
* Small code size both in terms of source code (the core library consists of a single
header file and a single source file) and compiled code.
See `Compile time and code bloat`_.
* Small code size both in terms of source code (the minimum configuration
consists of just three header files, ``core.h``, ``format.h`` and
``format-inl.h``) and compiled code. See `Compile time and code bloat`_.
* Reliability: the library has an extensive set of `unit tests
<https://github.com/fmtlib/fmt/tree/master/test>`_.
* Safety: the library is fully type safe, errors in format strings are
reported using exceptions, automatic memory management prevents buffer
overflow errors.

* Ease of use: small self-contained code base, no external dependencies,
permissive BSD `license

* `Portability <http://fmtlib.net/latest/index.html#portability>`_ with consistent output
across platforms and support for older compilers.

* Support for wide strings.
* Optional header-only configuration enabled with the ``FMT_HEADER_ONLY`` macro.

`extension API <http://fmtlib.net/latest/api.html#formatting-user-defined-types>`_:
friend std::ostream &operator<<(std::ostream &os, const Date &d) {
return os << d.year_ << '-' << d.month_ << '-' << d.day_;
.. code:: c++
#include "fmt/format.h"
struct date {
int year, month, day;
};
template <>
struct fmt::formatter<date> {
template <typename ParseContext>
constexpr auto parse(ParseContext &ctx) { return ctx.begin(); }
template <typename FormatContext>
auto format(const date &d, FormatContext &ctx) {
return format_to(ctx.begin(), "{}-{}-{}", d.year, d.month, d.day);
}
};
std::string s = fmt::format("The date is {}", Date(2012, 12, 9));
std::string s = fmt::format("The date is {}", date{2012, 12, 9});
// s == "The date is 2012-12-9"

API Reference
*************
All functions and classes provided by the fmt library reside
in namespace ``fmt`` and macros have prefix ``FMT_``. For brevity the
namespace is usually omitted in examples.
The {fmt} library API consists of the following parts:
Format API
==========
* :ref:`fmt/core.h <core-api>`: the core API providing argument handling
facilities and a lightweight subset of formatting functions
* :ref:`fmt/format.h <format-api>`: the full format API providing compile-time
format string checks, output iterator and user-defined type support
* :ref:`fmt/time.h <time-api>`: date and time formatting
* :ref:`fmt/ostream.h <ostream-api>`: ``std::ostream`` support
* :ref:`fmt/printf.h <printf-api>`: ``printf`` formatting
The following functions defined in ``fmt/format.h`` use :ref:`format string
syntax <syntax>` similar to the one used by Python's `str.format
<http://docs.python.org/3/library/stdtypes.html#str.format>`_ function.
All functions and types provided by the library reside in namespace ``fmt`` and

Core API
========
``fmt/core.h`` defines the core API which provides argument handling facilities
and a lightweight subset of formatting functions.
The following functions use :ref:`format string syntax <syntax>`
imilar to that of Python's `str.format
<http://docs.python.org/3/library/stdtypes.html#str.format>`_.
They take *format_str* and *args* as arguments.
*format_str* is a format string that contains literal text and replacement
fields surrounded by braces ``{}``. The fields are replaced with formatted
arguments in the resulting string.
*args* is an argument list representing arbitrary arguments.
The `performance of the format API
<https://github.com/fmtlib/fmt/blob/master/README.rst#speed-tests>`_ is close
to that of glibc's ``printf`` and better than the performance of IOStreams.
For even better speed use the `write API`_.
*args* is an argument list representing objects to be formatted.

Format API
==========
``fmt/format.h`` defines the full format API providing compile-time format
string checks, output iterator and user-defined type support.
Compile-time format string checks
---------------------------------
.. doxygendefine:: fmt
Formatting user-defined types
-----------------------------
To make a user-defined type formattable, specialize the ``formatter<T>`` struct
template and implement ``parse`` and ``format`` methods::
#include <fmt/format.h>
struct point { double x, y; };
namespace fmt {
template <>
struct formatter<point> {
template <typename ParseContext>
constexpr auto parse(ParseContext &ctx) { return ctx.begin(); }
template <typename FormatContext>
auto format(const point &p, FormatContext &ctx) {
return format_to(ctx.begin(), "({:.1f}, {:.1f})", p.x, p.y);
}
};
}
Then you can pass objects of type ``point`` to any formatting function::
point p = {1, 2};
std::string s = fmt::format("{}", p);
// s == "(1.0, 2.0)"
In the example above the ``formatter<point>::parse`` function ignores the
contents of the format string referred to by ``ctx.begin()`` so the object will
always be formatted in the same way. See ``formatter<tm>::parse`` in
:file:`fmt/time.h` for an advanced example of how to parse the format string and
customize the formatted output.
You can also reuse existing formatters, for example::
enum class color {red, green, blue};
template <>
struct fmt::formatter<color>: formatter<string_view> {
// parse is inherited from formatter<string_view>.
template <typename FormatContext>
auto format(color c, FormatContext &ctx) {
string_view name = "unknown";
switch (c) {
case color::red: name = "red"; break;
case color::green: name = "green"; break;
case color::blue: name = "blue"; break;
}
return formatter<string_view>::format(name, ctx);
}
};
This section shows how to define a custom format function for a user-defined
type. The next section describes how to get ``fmt`` to use a conventional stream
output ``operator<<`` when one is defined for a user-defined type.

.. doxygenfunction:: fmt::format_to_n(OutputIt, std::size_t, string_view, const Args&...)

:members:

System errors
-------------
fmt does not use ``errno`` to communicate errors to the user, but it may call
system functions which set ``errno``. Users should not make any assumptions about
the value of ``errno`` being preserved by library functions.

Custom allocators
-----------------
The {fmt} library supports custom dynamic memory allocators.
A custom allocator class can be specified as a template argument to
:class:`fmt::basic_memory_buffer`::
using custom_memory_buffer =
fmt::basic_memory_buffer<char, fmt::inline_buffer_size, custom_allocator>;
It is also possible to write a formatting function that uses a custom
allocator::
using custom_string =
std::basic_string<char, std::char_traits<char>, custom_allocator>;
custom_string vformat(custom_allocator alloc, fmt::string_view format_str,
fmt::format_args args) {
custom_memory_buffer buf(alloc);
fmt::vformat_to(buf, format_str, args);
return custom_string(buf.data(), buf.size(), alloc);
}
template <typename ...Args>
inline custom_string format(custom_allocator alloc,
fmt::string_view format_str,
const Args & ... args) {
return vformat(alloc, format_str, fmt::make_format_args(args...));
}
The allocator will be used for the output container only. If you are using named
arguments, the container that stores pointers to them will be allocated using
the default allocator. Also floating-point formatting falls back on ``sprintf``
which may do allocations.
Custom formatting of built-in types
-----------------------------------
It is possible to change the way arguments are formatted by providing a
custom argument formatter class::
using arg_formatter =
fmt::arg_formatter<fmt::back_insert_range<fmt::internal::buffer>>;
// A custom argument formatter that formats negative integers as unsigned
// with the ``x`` format specifier.
class custom_arg_formatter : public arg_formatter {
public:
custom_arg_formatter(fmt::format_context &ctx, fmt::format_specs &spec)
: arg_formatter(ctx, spec) {}
using arg_formatter::operator();
auto operator()(int value) {
if (spec().type() == 'x')
return (*this)(static_cast<unsigned>(value)); // convert to unsigned and format
return arg_formatter::operator()(value);
}
};
std::string custom_vformat(fmt::string_view format_str, fmt::format_args args) {
fmt::memory_buffer buffer;
// Pass custom argument formatter as a template arg to vformat_to.
fmt::vformat_to<custom_arg_formatter>(buffer, format_str, args);
return fmt::to_string(buffer);
}
template <typename ...Args>
inline std::string custom_format(
fmt::string_view format_str, const Args &... args) {
return custom_vformat(format_str, fmt::make_format_args(args...));

The format string syntax is described in the documentation of
`strftime <http://en.cppreference.com/w/cpp/chrono/c/strftime>`_.
Formatting user-defined types
-----------------------------
A custom ``format_arg`` function may be implemented and used to format any
user-defined type. That is how date and time formatting described in the
previous section is implemented in :file:`fmt/time.h`. The following example
shows how to implement custom formatting for a user-defined structure.
::
struct MyStruct { double a, b; };
void format_arg(fmt::BasicFormatter<char> &f,
const char *&format_str, const MyStruct &s) {
f.writer().write("[MyStruct: a={:.1f}, b={:.2f}]", s.a, s.b);
}
MyStruct m = { 1, 2 };
std::string s = fmt::format("m={}", n);
// s == "m=[MyStruct: a=1.0, b=2.00]"
Note in the example above the ``format_arg`` function ignores the contents of
``format_str`` so the type will always be formatted as specified. See
``format_arg`` in :file:`fmt/time.h` for an advanced example of how to use
the ``format_str`` argument to customize the formatted output.
This technique can also be used for formatting class hierarchies::
namespace local {
struct Parent {
Parent(int p) : p(p) {}
virtual void write(fmt::Writer &w) const {
w.write("Parent : p={}", p);
}
int p;
};
struct Child : Parent {
Child(int c, int p) : Parent(p), c(c) {}
virtual void write(fmt::Writer &w) const {
w.write("Child c={} : ", c);
Parent::write(w);
}
int c;
};
void format_arg(fmt::BasicFormatter<char> &f,
const char *&format_str, const Parent &p) {
p.write(f.writer());
}
}
Local::Child c(1,2);
Local::Parent &p = c;
fmt::print("via ref to base: {}\n", p);
fmt::print("direct to child: {}\n", c);

The write API provides classes for writing formatted data into character

may result in larger compiled code size. The main writer class is

Custom allocators
=================
The fmt library supports custom dynamic memory allocators.
A custom allocator class can be specified as a template argument to
:class:`fmt::BasicMemoryWriter`::
typedef fmt::BasicMemoryWriter<char, CustomAllocator> CustomMemoryWriter;
It is also possible to write a formatting function that uses a custom
allocator::
typedef std::basic_string<char, std::char_traits<char>, CustomAllocator>
CustomString;
CustomString format(CustomAllocator alloc, fmt::CStringRef format_str,
fmt::ArgList args) {
CustomMemoryWriter writer(alloc);
writer.write(format_str, args);
return CustomString(writer.data(), writer.size(), alloc);
}

Note that fmt does not use the value of the ``errno`` global to communicate
errors to the user, but it may call system functions which set ``errno``. Since
fmt does not attempt to preserve the value of ``errno``, users should not make
any assumptions about it and always set it to ``0`` before making any system
calls that convey error information via ``errno``.
Compact binary code
-------------------
The library is designed to produce compact per-call compiled code. For example
(`godbolt <https://godbolt.org/g/TZU4KF>`_),
.. code:: c++
#include <fmt/core.h>
int main() {
fmt::print("The answer is {}.", 42);
}

.. _portability:
Portability
-----------
The library is highly portable. Here is an incomplete list of operating systems
and compilers where it has been tested and known to work:
The library is highly portable and relies only on a small set of C++11 features:
* 64-bit (amd64) GNU/Linux with GCC 4.4.3,
`4.6.3 <https://travis-ci.org/fmtlib/fmt>`_, 4.7.2, 4.8.1, and Intel C++
Compiler (ICC) 14.0.2
* variadic templates
* type traits
* rvalue references
* decltype
* trailing return types
* deleted functions
* 32-bit (i386) GNU/Linux with GCC 4.4.3, 4.6.3
* Mac OS X with GCC 4.2.1 and Clang 4.2, 5.1.0
* 64-bit Windows with Visual C++ 2010, 2013 and
`2015 <https://ci.appveyor.com/project/vitaut/fmt>`_
* 32-bit Windows with Visual C++ 2010
Although the library uses C++11 features when available, it also works with
older compilers and standard library implementations. The only thing to keep in
mind for C++98 portability:
* Variadic templates: minimum GCC 4.4, Clang 2.9 or VS2013. This feature allows
the Format API to accept an unlimited number of arguments. With older
compilers the maximum is 15.
* User-defined literals: minimum GCC 4.7, Clang 3.1 or VS2015. The suffixes
``_format`` and ``_a`` are functionally equivalent to the functions
``fmt::format`` and ``fmt::arg``.
These 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 only requires C++98.

A ``printf`` argument formatter based on the `curiously recurring template

To use `~fmt::BasicPrintfArgFormatter` define a subclass that implements some

`~fmt::ArgVisitor`, for example, `~fmt::ArgVisitor::visit_int()`.
Pass the subclass as the *Impl* template parameter. When a formatting
function processes an argument, it will dispatch to a visit method
specific to the argument type. For example, if the argument type is
``double`` then the `~fmt::ArgVisitor::visit_double()` method of a subclass
will be called. If the subclass doesn't contain a method with this signature,
then a corresponding method of `~fmt::BasicPrintfArgFormatter` or its
