+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 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>`_).

+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:
+
+ .. image:: https://user-images.githubusercontent.com/576385/
+ 50405788-b66e7500-076e-11e9-9592-7324d1f951d8.png
+
+ 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:
+
+ .. image:: https://user-images.githubusercontent.com/576385/
+ 50405925-dbfc7e00-0770-11e9-9b85-333fab0af9ac.png
+
+ Thanks `@Rakete1111 (Nicolas) <https://github.com/Rakete1111>`_.
+

+ `#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``

+ `@DarkDimius (Dmitry Petrashko) <https://github.com/DarkDimius>`_,
+ `@HecticSerenity <https://github.com/HecticSerenity>`_.
+
+* Added pkgconfig support which makes it easier to consume the library from
+ meson and other build systems
+ (`#916 <https://github.com/fmtlib/fmt/pull/916>`_).
+ Thanks `@colemickens (Cole Mickens) <https://github.com/colemickens>`_.

+
+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>`_,

+ `@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>`_,

+
+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/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
+ <https://fmt.dev/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
+ <https://fmt.dev/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
+ <https://fmt.dev/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 <https://fmt.dev/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
+ <https://fmt.dev/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
+ <https://fmt.dev/dev/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>`_,
+ `#617 <https://github.com/fmtlib/fmt/pull/617>`_,

+ `@mihaitodor (Mihai Todor) <https://github.com/mihaitodor>`_, and
+ `@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>`_.

+
+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>`_).
+ Thanks to `@dean0x7d (Dean Moldovan) <https://github.com/dean0x7d>`_ and
+ `@speth (Ray Speth) <https://github.com/speth>`_.

+
+ .. 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

+
+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/>`_:
+
+ .. |old| image:: https://cloud.githubusercontent.com/assets/576385/4792130/

+ | Old | New |
+ +-------+-------+
+ | |old| | |new| |
+ +-------+-------+
+
+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

+**{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 <https://fmt.dev/latest/>`__
+
+Q&A: ask questions on `StackOverflow with the tag fmt <http://stackoverflow.com/questions/tagged/fmt>`_.
+
+Features
+--------
+
+* Replacement-based `format API <https://fmt.dev/dev/api.html>`_ with
+ positional arguments for localization.
+* `Format string syntax <https://fmt.dev/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
+ <https://fmt.dev/latest/api.html#printf-formatting>`_ including
+ the POSIX extension for positional arguments.
+* Implementation of `C++20 std::format <https://fmt.dev/Text%20Formatting.html>`__.
+* Support for user-defined types.
+* High performance: faster than common standard library implementations of
+ `printf <http://en.cppreference.com/w/cpp/io/c/fprintf>`_ and
+ 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 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 can be
+ reported at compile time, automatic memory management prevents buffer overflow
+ errors.
+* Ease of use: small self-contained code base, no external dependencies,
+ permissive MIT `license
+ <https://github.com/fmtlib/fmt/blob/master/LICENSE.rst>`_
+* `Portability <https://fmt.dev/latest/index.html#portability>`_ with
+ consistent output across platforms and support for older compilers.
+* Clean warning-free codebase even on high warning levels
+ (``-Wall -Wextra -pedantic``).
+* Support for wide strings.
+* Optional header-only configuration enabled with the ``FMT_HEADER_ONLY`` macro.
+
+See the `documentation <https://fmt.dev/latest/>`_ for more details.
+
+Examples
+--------
+
+Print ``Hello, world!`` to ``stdout``:
+
+.. code:: c++
+
+ fmt::print("Hello, {}!", "world"); // Python-like format string syntax
+ fmt::printf("Hello, %s!", "world"); // printf format string syntax
+
+Format a string and use positional arguments:
+
+.. code:: c++
+
+ std::string s = fmt::format("I'd rather be {1} than {0}.", "right", "happy");
+ // s == "I'd rather be happy than right."
+
+Check a format string at compile time:
+
+.. code:: c++
+
+ // test.cc
+ #define FMT_STRING_ALIAS 1
+ #include <fmt/format.h>
+ std::string s = format(fmt("{2}"), 42);
+
+.. code::
+
+ $ c++ -Iinclude -std=c++14 test.cc
+ ...
+ test.cc:4:17: note: in instantiation of function template specialization 'fmt::v5::format<S, int>' requested here
+ std::string s = format(fmt("{2}"), 42);
+ ^
+ include/fmt/core.h:778:19: note: non-constexpr function 'on_error' cannot be used in a constant expression
+ ErrorHandler::on_error(message);
+ ^
+ include/fmt/format.h:2226:16: note: in call to '&checker.context_->on_error(&"argument index out of range"[0])'
+ context_.on_error("argument index out of range");
+ ^
+
+Use {fmt} as a safe portable replacement for ``itoa``
+(`godbolt <https://godbolt.org/g/NXmpU4>`_):
+
+.. code:: c++
+
+ fmt::memory_buffer buf;
+ format_to(buf, "{}", 42); // replaces itoa(42, buffer, 10)
+ format_to(buf, "{:x}", 42); // replaces itoa(42, buffer, 16)
+ // access the string with to_string(buf) or buf.data()
+
+Format objects of user-defined types via a simple `extension API
+<https://fmt.dev/latest/api.html#formatting-user-defined-types>`_:
+
+.. 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.out(), "{}-{}-{}", 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"
+
+Create your own functions similar to `format
+<https://fmt.dev/latest/api.html#format>`_ and
+`print <https://fmt.dev/latest/api.html#print>`_
+which take arbitrary arguments (`godbolt <https://godbolt.org/g/MHjHVf>`_):
+
+.. 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...));
+ }
+
+ report_error("file not found: {}", path);
+
+Note that ``vreport_error`` is not parameterized on argument types which can
+improve compile times and reduce code size compared to a fully parameterized
+version.

+Benchmarks
+----------
+
+Speed tests
+~~~~~~~~~~~
+
+================= ============= ===========
+Library Method Run Time, s
+================= ============= ===========
+libc printf 1.01
+libc++ std::ostream 3.04
+{fmt} 1632f72 fmt::print 0.86
+tinyformat 2.0.1 tfm::printf 3.23
+Boost Format 1.67 boost::format 7.98
+Folly Format folly::format 2.23
+================= ============= ===========
+
+{fmt} is the fastest of the benchmarked methods, ~17% faster than ``printf``.
+
+The above results were generated by building ``tinyformat_test.cpp`` on macOS
+10.14.3 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>`_:
+
+.. image:: https://user-images.githubusercontent.com/576385/54883977-9fe8c000-4e28-11e9-8bde-272d122e7c52.jpg

+
+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.
+
+**Optimized build (-O3)**
+
+============= =============== ==================== ==================
+Method Compile Time, s Executable size, KiB Stripped size, KiB
+============= =============== ==================== ==================
+printf 2.6 29 26
+printf+string 16.4 29 26
+iostreams 31.1 59 55
+{fmt} 19.0 37 34
+tinyformat 44.0 103 97
+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.
+
+**Non-optimized build**
+
+============= =============== ==================== ==================
+Method Compile Time, s Executable size, KiB Stripped size, KiB
+============= =============== ==================== ==================
+printf 2.2 33 30
+printf+string 16.0 33 30
+iostreams 28.3 56 52
+{fmt} 18.2 59 50
+tinyformat 32.6 88 82
+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 and tinyformat are
+header-only libraries so they don't provide any linkage options.
+
+Running the tests
+~~~~~~~~~~~~~~~~~
+
+Please refer to `Building the library`__ for the instructions on how to build
+the library and run the unit tests.
+
+__ https://fmt.dev/latest/usage.html#building-the-library
+
+Benchmarks reside in a separate repository,
+`format-benchmarks <https://github.com/fmtlib/format-benchmark>`_,
+so to run the benchmarks you first need to clone this repository and
+generate Makefiles with CMake::
+
+ $ git clone --recursive https://github.com/fmtlib/format-benchmark.git
+ $ cd format-benchmark
+ $ cmake .
+
+Then you can run the speed test::
+
+ $ make speed-test
+
+or the bloat test::
+
+ $ make bloat-test

+
+Motivation
+----------
+
+So why yet another formatting library?
+
+There are plenty of methods for doing this task, from standard ones like
+the printf family of function and iostreams to Boost Format and FastFormat
+libraries. The reason for creating a new library is that every existing
+solution that I found either had serious issues or didn't provide
+all the features I needed.
+
+printf
+~~~~~~
+
+The good thing about ``printf`` is that it is pretty fast and readily available
+being a part of the C standard library. The main drawback is that it
+doesn't support user-defined types. ``printf`` also has safety issues although
+they are somewhat mitigated with `__attribute__ ((format (printf, ...))
+<http://gcc.gnu.org/onlinedocs/gcc/Function-Attributes.html>`_ in GCC.
+There is a POSIX extension that adds positional arguments required for
+`i18n <https://en.wikipedia.org/wiki/Internationalization_and_localization>`_
+to ``printf`` but it is not a part of C99 and may not be available on some
+platforms.
+
+iostreams
+~~~~~~~~~
+
+The main issue with iostreams is best illustrated with an example:
+
+.. code:: c++
+
+ std::cout << std::setprecision(2) << std::fixed << 1.23456 << "\n";
+
+which is a lot of typing compared to printf:
+
+.. code:: c++
+
+ printf("%.2f\n", 1.23456);
+
+Matthew Wilson, the author of FastFormat, called this "chevron hell". iostreams
+don't support positional arguments by design.
+
+The good part is that iostreams support user-defined types and are safe although
+error handling is awkward.
+
+Boost Format
+~~~~~~~~~~~~
+
+This is a very powerful library which supports both ``printf``-like format
+strings and positional arguments. Its main drawback is performance. According to
+various benchmarks it is much slower than other methods considered here. Boost
+Format also has excessive build times and severe code bloat issues (see
+`Benchmarks`_).
+
+FastFormat
+~~~~~~~~~~
+
+This is an interesting library which is fast, safe and has positional
+arguments. However it has significant limitations, citing its author:
+
+ Three features that have no hope of being accommodated within the
+ current design are:
+
+ * Leading zeros (or any other non-space padding)
+ * Octal/hexadecimal encoding
+ * Runtime width/alignment specification
+
+It is also quite big and has a heavy dependency, STLSoft, which might be
+too restrictive for using it in some projects.
+
+Loki SafeFormat
+~~~~~~~~~~~~~~~
+
+SafeFormat is a formatting library which uses ``printf``-like format strings and
+is type safe. It doesn't support user-defined types or positional arguments and
+makes unconventional use of ``operator()`` for passing format arguments.
+
+Tinyformat
+~~~~~~~~~~
+
+This library supports ``printf``-like format strings and is very small .
+It doesn't support positional arguments and wrapping it in C++98 is somewhat
+difficult. Tinyformat relies on iostreams which limits its performance.
+
+Boost Spirit.Karma
+~~~~~~~~~~~~~~~~~~
+
+This is not really a formatting library but I decided to include it here for
+completeness. As iostreams, it suffers from the problem of mixing verbatim text
+with arguments. The library is pretty fast, but slower on integer formatting
+than ``fmt::format_int`` on Karma's own benchmark,
+see `Fast integer to string conversion in C++
+<http://zverovich.net/2013/09/07/integer-to-string-conversion-in-cplusplus.html>`_.
+
+FAQ
+---
+
+Q: how can I capture formatting arguments and format them later?
+
+A: use ``std::tuple``:
+
+.. code:: c++
+
+ template <typename... Args>
+ auto capture(const Args&... args) {
+ return std::make_tuple(args...);
+ }
+
+ auto print_message = [](const auto&... args) {
+ fmt::print(args...);
+ };
+
+ // Capture and store arguments:
+ auto args = capture("{} {}", 42, "foo");
+ // Do formatting:
+ std::apply(print_message, args);

+*************
+API Reference
+*************
+
+The {fmt} library API consists of the following parts:
+
+* :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/chrono.h <chrono-api>`: date and time formatting
+* :ref:`fmt/ostream.h <ostream-api>`: ``std::ostream`` support
+* :ref:`fmt/printf.h <printf-api>`: ``printf`` formatting
+
+All functions and types provided by the library reside in namespace ``fmt`` and
+macros have prefix ``FMT_`` or ``fmt``.
+
+.. _core-api:
+
+Core API
+========
+
+``fmt/core.h`` defines the core API which provides argument handling facilities
+and a lightweight subset of formatting functions. In the header-only mode
+include ``fmt/format.h`` instead of ``fmt/core.h``.
+
+The following functions use :ref:`format string syntax <syntax>`
+similar 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. A function taking *format_str* doesn't
+participate in an overload resolution if the latter is not a string.
+
+*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_STRING
+.. 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.out(), "({:.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/chrono.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);
+ }
+ };
+
+You can also write a formatter for a hierarchy of classes::
+
+ #include <type_traits>
+ #include <fmt/format.h>
+
+ struct A {
+ virtual ~A() {}
+ virtual std::string name() const { return "A"; }
+ };
+
+ struct B : A {
+ virtual std::string name() const { return "B"; }
+ };
+
+ template <typename T>
+ struct fmt::formatter<T, std::enable_if_t<std::is_base_of<A, T>::value, char>> :
+ fmt::formatter<std::string> {
+ template <typename FormatCtx>
+ auto format(const A& a, FormatCtx& ctx) {
+ return fmt::formatter<std::string>::format(a.name(), ctx);
+ }
+ };
+
+ int main() {
+ B b;
+ A& a = b;
+ fmt::print("{}", a); // prints "B"
+ }
+
+Output Iterator Support
+-----------------------
+
+.. doxygenfunction:: fmt::format_to(OutputIt, const S&, Args&&...)
+.. doxygenfunction:: fmt::format_to_n(OutputIt, std::size_t, string_view, Args&&...)
+.. doxygenstruct:: fmt::format_to_n_result

+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::buffer_range<char>>;
+
+ // 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_parse_context* parse_ctx = nullptr,
+ fmt::format_specs* spec = nullptr)
+ : arg_formatter(ctx, parse_ctx, spec) {}
+
+ using arg_formatter::operator();
+
+ auto operator()(int value) {
+ if (specs() && specs()->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...));
+ }
+
+ std::string s = custom_format("{:x}", -42); // s == "ffffffd6"
+
+.. doxygenclass:: fmt::arg_formatter
+ :members:
+
+.. _chrono-api:
+
+Date and Time Formatting
+========================
+
+The library supports `strftime
+<http://en.cppreference.com/w/cpp/chrono/c/strftime>`_-like date and time
+formatting::
+
+ #include <fmt/chrono.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));
+
+The format string syntax is described in the documentation of
+`strftime <http://en.cppreference.com/w/cpp/chrono/c/strftime>`_.
+
+.. _ostream-api:
+
+``std::ostream`` Support
+========================
+
+``fmt/ostream.h`` provides ``std::ostream`` support including formatting of
+user-defined types that have overloaded ``operator<<``::
+
+ #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"
+
+.. doxygenfunction:: print(std::basic_ostream<Char>&, const S&, Args&&...)
+
+.. _printf-api:
+
+``printf`` Formatting
+=====================
+
+The header ``fmt/printf.h`` provides ``printf``-like formatting functionality.
+The following functions use `printf format string syntax
+<http://pubs.opengroup.org/onlinepubs/009695399/functions/fprintf.html>`_ with
+the POSIX extension for positional arguments. Unlike their standard
+counterparts, the ``fmt`` functions are type-safe and throw an exception if an
+argument type doesn't match its format specification.
+
+.. doxygenfunction:: printf(const S&, const Args&...)
+
+.. doxygenfunction:: fprintf(std::FILE *, const S&, const Args&...)
+
+.. doxygenfunction:: fprintf(std::basic_ostream<Char>&, const S&, const Args&...)
+
+.. doxygenfunction:: sprintf(const S&, const Args&...)

+Overview
+========
+
+**fmt** is an open-source formatting library.
+It can be used as a fast and safe alternative to printf and IOStreams.
+
+.. raw:: html
+
+ <div class="panel panel-default">
+ <div class="panel-heading">What users say:</div>
+ <div class="panel-body">
+ Thanks for creating this library. It’s been a hole in C++ for a long
+ time. I’ve used both boost::format and loki::SPrintf, and neither felt
+ like the right answer. This does.
+ </div>
+ </div>
+
+.. _format-api-intro:
+
+Format API
+----------
+
+The replacement-based Format API provides a safe alternative to ``printf``,
+``sprintf`` and friends with comparable or `better performance
+<http://zverovich.net/2013/09/07/integer-to-string-conversion-in-cplusplus.html>`_.
+The `format string syntax <syntax.html>`_ is similar to the one used by
+`str.format <http://docs.python.org/3/library/stdtypes.html#str.format>`_
+in Python:
+
+.. code:: c++
+
+ fmt::format("The answer is {}.", 42);
+
+The ``fmt::format`` function returns a string "The answer is 42.". You can use
+``fmt::memory_buffer`` to avoid constructing ``std::string``:
+
+.. code:: c++
+
+ fmt::memory_buffer out;
+ format_to(out, "For a moment, {} happened.", "nothing");
+ out.data(); // returns a pointer to the formatted data
+
+The ``fmt::print`` function performs formatting and writes the result to a stream:
+
+.. code:: c++
+
+ fmt::print(stderr, "System error code = {}\n", errno);
+
+The file argument can be omitted in which case the function prints to
+``stdout``:
+
+.. code:: c++
+
+ fmt::print("Don't {}\n", "panic");
+
+The Format API also supports positional arguments useful for localization:
+
+.. code:: c++
+
+ fmt::print("I'd rather be {1} than {0}.", "right", "happy");
+
+Named arguments can be created with ``fmt::arg``. This makes it easier to track
+what goes where when multiple values are being inserted:
+
+.. code:: c++
+
+ fmt::print("Hello, {name}! The answer is {number}. Goodbye, {name}.",
+ fmt::arg("name", "World"), fmt::arg("number", 42));
+
+If your compiler supports C++11 user-defined literals, the suffix ``_a`` offers
+an alternative, slightly terser syntax for named arguments:
+
+.. code:: c++
+
+ fmt::print("Hello, {name}! The answer is {number}. Goodbye, {name}.",
+ "name"_a="World", "number"_a=42);
+
+The ``_format`` suffix may be used to format string literals similar to Python:
+
+.. code:: c++
+
+ std::string message = "{0}{1}{0}"_format("abra", "cad");
+
+Other than the placement of the format string on the left of the operator,
+``_format`` is functionally identical to ``fmt::format``. In order to use the
+literal operators, they must be made visible with the directive
+``using namespace fmt::literals;``. Note that this brings in only ``_a`` and
+``_format`` but nothing else from the ``fmt`` namespace.
+
+.. _safety:
+
+Safety
+------
+
+The library is fully type safe, automatic memory management prevents buffer
+overflow, errors in format strings are reported using exceptions or at compile
+time. For example, the code
+
+.. code:: c++
+
+ fmt::format("The answer is {:d}", "forty-two");
+
+throws a ``format_error`` exception with description "unknown format code 'd' for
+string", because the argument ``"forty-two"`` is a string while the format code
+``d`` only applies to integers, while
+
+.. code:: c++
+
+ format(fmt("The answer is {:d}"), "forty-two");
+
+reports a compile-time error for the same reason on compilers that support
+relaxed ``constexpr``. See `here <api.html#c.fmt>`_ for how to enable
+compile-time checks.
+
+The following code
+
+.. code:: c++
+
+ fmt::format("Cyrillic letter {}", L'\x42e');
+
+produces a compile-time error because wide character ``L'\x42e'`` cannot be
+formatted into a narrow string. You can use a wide format string instead:
+
+.. code:: c++
+
+ fmt::format(L"Cyrillic letter {}", L'\x42e');
+
+For comparison, writing a wide character to ``std::ostream`` results in
+its numeric value being written to the stream (i.e. 1070 instead of letter 'ю'
+which is represented by ``L'\x42e'`` if we use Unicode) which is rarely what is
+needed.
+
+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);
+ }
+
+compiles to just
+
+.. code:: asm
+
+ main: # @main
+ sub rsp, 24
+ mov qword ptr [rsp], 42
+ mov rcx, rsp
+ mov edi, offset .L.str
+ mov esi, 17
+ mov edx, 2
+ call fmt::v5::vprint(fmt::v5::basic_string_view<char>, fmt::v5::format_args)
+ xor eax, eax
+ add rsp, 24
+ ret
+ .L.str:
+ .asciz "The answer is {}."
+
+.. _portability:
+
+Portability
+-----------
+
+The library is highly portable and relies only on a small set of C++11 features:
+
+* variadic templates
+* type traits
+* rvalue references
+* decltype
+* trailing return types
+* deleted functions
+* alias templates
+
+These are available since GCC 4.8, Clang 3.0 and MSVC 19.0 (2015). 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.
+
+The output of all formatting functions is consistent across platforms. In
+particular, formatting a floating-point infinity always gives ``inf`` while the
+output of ``printf`` is platform-dependent in this case. For example,
+
+.. code::
+
+ fmt::print("{}", std::numeric_limits<double>::infinity());
+
+always prints ``inf``.
+
+.. _ease-of-use:
+
+Ease of Use
+-----------
+
+fmt has a small self-contained code base with the core library consisting of
+just three header files and no external dependencies.
+A permissive BSD `license <https://github.com/fmtlib/fmt#license>`_ allows
+using the library both in open-source and commercial projects.

+A. HISTORY OF THE SOFTWARE
+==========================
+
+Python was created in the early 1990s by Guido van Rossum at Stichting
+Mathematisch Centrum (CWI, see http://www.cwi.nl) in the Netherlands
+as a successor of a language called ABC. Guido remains Python's
+principal author, although it includes many contributions from others.
+
+In 1995, Guido continued his work on Python at the Corporation for
+National Research Initiatives (CNRI, see http://www.cnri.reston.va.us)
+in Reston, Virginia where he released several versions of the
+software.
+
+In May 2000, Guido and the Python core development team moved to
+BeOpen.com to form the BeOpen PythonLabs team. In October of the same
+year, the PythonLabs team moved to Digital Creations (now Zope
+Corporation, see http://www.zope.com). In 2001, the Python Software
+Foundation (PSF, see http://www.python.org/psf/) was formed, a
+non-profit organization created specifically to own Python-related
+Intellectual Property. Zope Corporation is a sponsoring member of
+the PSF.
+
+All Python releases are Open Source (see http://www.opensource.org for
+the Open Source Definition). Historically, most, but not all, Python
+releases have also been GPL-compatible; the table below summarizes
+the various releases.

+Footnotes:
+
+(1) GPL-compatible doesn't mean that we're distributing Python under
+ the GPL. All Python licenses, unlike the GPL, let you distribute
+ a modified version without making your changes open source. The
+ GPL-compatible licenses make it possible to combine Python with
+ other software that is released under the GPL; the others don't.
+
+(2) According to Richard Stallman, 1.6.1 is not GPL-compatible,
+ because its license has a choice of law clause. According to
+ CNRI, however, Stallman's lawyer has told CNRI's lawyer that 1.6.1
+ is "not incompatible" with the GPL.
+
+Thanks to the many outside volunteers who have worked under Guido's
+direction to make these releases possible.

+Format String Syntax
+********************
+
+Formatting functions such as :ref:`fmt::format() <format>` and
+:ref:`fmt::print() <print>` use the same format string syntax described in this
+section.
+
+Format strings contain "replacement fields" surrounded by curly braces ``{}``.
+Anything that is not contained in braces is considered literal text, which is
+copied unchanged to the output. If you need to include a brace character in the
+literal text, it can be escaped by doubling: ``{{`` and ``}}``.
+
+The grammar for a replacement field is as follows:
+
+.. productionlist:: sf
+ replacement_field: "{" [`arg_id`] [":" `format_spec`] "}"
+ arg_id: `integer` | `identifier`
+ integer: `digit`+
+ digit: "0"..."9"
+ identifier: `id_start` `id_continue`*
+ id_start: "a"..."z" | "A"..."Z" | "_"
+ id_continue: `id_start` | `digit`
+
+In less formal terms, the replacement field can start with an *arg_id*
+that specifies the argument whose value is to be formatted and inserted into
+the output instead of the replacement field.
+The *arg_id* is optionally followed by a *format_spec*, which is preceded
+by a colon ``':'``. These specify a non-default format for the replacement value.
+
+See also the :ref:`formatspec` section.
+
+If the numerical arg_ids in a format string are 0, 1, 2, ... in sequence,
+they can all be omitted (not just some) and the numbers 0, 1, 2, ... will be
+automatically inserted in that order.
+
+Named arguments can be referred to by their names or indices.
+
+Some simple format string examples::
+
+ "First, thou shalt count to {0}" // References the first argument
+ "Bring me a {}" // Implicitly references the first argument
+ "From {} to {}" // Same as "From {0} to {1}"
+
+The *format_spec* field contains a specification of how the value should be
+presented, including such details as field width, alignment, padding, decimal
+precision and so on. Each value type can define its own "formatting
+mini-language" or interpretation of the *format_spec*.
+
+Most built-in types support a common formatting mini-language, which is
+described in the next section.
+
+A *format_spec* field can also include nested replacement fields in certain
+positions within it. These nested replacement fields can contain only an
+argument id; format specifications are not allowed. This allows the formatting
+of a value to be dynamically specified.
+
+See the :ref:`formatexamples` section for some examples.
+
+.. _formatspec:
+
+Format Specification Mini-Language
+==================================
+
+"Format specifications" are used within replacement fields contained within a
+format string to define how individual values are presented (see
+:ref:`syntax`). Each formattable type may define how the format
+specification is to be interpreted.
+
+Most built-in types implement the following options for format specifications,
+although some of the formatting options are only supported by the numeric types.
+
+The general form of a *standard format specifier* is:
+
+.. productionlist:: sf
+ format_spec: [[`fill`]`align`][`sign`]["#"]["0"][`width`]["." `precision`][`type`]
+ fill: <a character other than '{', '}' or '\0'>
+ align: "<" | ">" | "=" | "^"
+ sign: "+" | "-" | " "
+ width: `integer` | "{" `arg_id` "}"
+ precision: `integer` | "{" `arg_id` "}"
+ type: `int_type` | "a" | "A" | "c" | "e" | "E" | "f" | "F" | "g" | "G" | "p" | "s"
+ int_type: "b" | "B" | "d" | "n" | "o" | "x" | "X"
+
+The *fill* character can be any character other than '{', '}' or '\\0'. The
+presence of a fill character is signaled by the character following it, which
+must be one of the alignment options. If the second character of *format_spec*
+is not a valid alignment option, then it is assumed that both the fill character
+and the alignment option are absent.
+
+The meaning of the various alignment options is as follows:
+
++---------+----------------------------------------------------------+
+| Option | Meaning |
++=========+==========================================================+
+| ``'<'`` | Forces the field to be left-aligned within the available |
+| | space (this is the default for most objects). |
++---------+----------------------------------------------------------+
+| ``'>'`` | Forces the field to be right-aligned within the |
+| | available space (this is the default for numbers). |
++---------+----------------------------------------------------------+
+| ``'^'`` | Forces the field to be centered within the available |
+| | space. |
++---------+----------------------------------------------------------+
+
+Note that unless a minimum field width is defined, the field width will always
+be the same size as the data to fill it, so that the alignment option has no
+meaning in this case.
+
+The *sign* option is only valid for number types, and can be one of the
+following:
+
++---------+----------------------------------------------------------+
+| Option | Meaning |
++=========+==========================================================+
+| ``'+'`` | indicates that a sign should be used for both |
+| | positive as well as negative numbers. |
++---------+----------------------------------------------------------+
+| ``'-'`` | indicates that a sign should be used only for negative |
+| | numbers (this is the default behavior). |
++---------+----------------------------------------------------------+
+| space | indicates that a leading space should be used on |
+| | positive numbers, and a minus sign on negative numbers. |
++---------+----------------------------------------------------------+
+
+The ``'#'`` option causes the "alternate form" to be used for the
+conversion. The alternate form is defined differently for different
+types. This option is only valid for integer and floating-point types.
+For integers, when binary, octal, or hexadecimal output is used, this
+option adds the prefix respective ``"0b"`` (``"0B"``), ``"0"``, or
+``"0x"`` (``"0X"``) to the output value. Whether the prefix is
+lower-case or upper-case is determined by the case of the type
+specifier, for example, the prefix ``"0x"`` is used for the type ``'x'``
+and ``"0X"`` is used for ``'X'``. For floating-point numbers the
+alternate form causes the result of the conversion to always contain a
+decimal-point character, even if no digits follow it. Normally, a
+decimal-point character appears in the result of these conversions
+only if a digit follows it. In addition, for ``'g'`` and ``'G'``
+conversions, trailing zeros are not removed from the result.
+
+.. ifconfig:: False
+
+ The ``','`` option signals the use of a comma for a thousands separator.
+ For a locale aware separator, use the ``'n'`` integer presentation type
+ instead.
+
+*width* is a decimal integer defining the minimum field width. If not
+specified, then the field width will be determined by the content.
+
+Preceding the *width* field by a zero (``'0'``) character enables sign-aware
+zero-padding for numeric types. It forces the padding to be placed after the
+sign or base (if any) but before the digits. This is used for printing fields in
+the form '+000000120'. This option is only valid for numeric types and it has no
+effect on formatting of infinity and NaN.
+
+The *precision* is a decimal number indicating how many digits should be
+displayed after the decimal point for a floating-point value formatted with
+``'f'`` and ``'F'``, or before and after the decimal point for a floating-point
+value formatted with ``'g'`` or ``'G'``. For non-number types the field
+indicates the maximum field size - in other words, how many characters will be
+used from the field content. The *precision* is not allowed for integer,
+character, Boolean, and pointer values.
+
+Finally, the *type* determines how the data should be presented.
+
+The available string presentation types are:
+
++---------+----------------------------------------------------------+
+| Type | Meaning |
++=========+==========================================================+
+| ``'s'`` | String format. This is the default type for strings and |
+| | may be omitted. |
++---------+----------------------------------------------------------+
+| none | The same as ``'s'``. |
++---------+----------------------------------------------------------+
+
+The available character presentation types are:
+
++---------+----------------------------------------------------------+
+| Type | Meaning |
++=========+==========================================================+
+| ``'c'`` | Character format. This is the default type for |
+| | characters and may be omitted. |
++---------+----------------------------------------------------------+
+| none | The same as ``'c'``. |
++---------+----------------------------------------------------------+
+
+The available integer presentation types are:
+
++---------+----------------------------------------------------------+
+| Type | Meaning |
++=========+==========================================================+
+| ``'b'`` | Binary format. Outputs the number in base 2. Using the |
+| | ``'#'`` option with this type adds the prefix ``"0b"`` |
+| | to the output value. |
++---------+----------------------------------------------------------+
+| ``'B'`` | Binary format. Outputs the number in base 2. Using the |
+| | ``'#'`` option with this type adds the prefix ``"0B"`` |
+| | to the output value. |
++---------+----------------------------------------------------------+
+| ``'d'`` | Decimal integer. Outputs the number in base 10. |
++---------+----------------------------------------------------------+
+| ``'o'`` | Octal format. Outputs the number in base 8. |
++---------+----------------------------------------------------------+
+| ``'x'`` | Hex format. Outputs the number in base 16, using |
+| | lower-case letters for the digits above 9. Using the |
+| | ``'#'`` option with this type adds the prefix ``"0x"`` |
+| | to the output value. |
++---------+----------------------------------------------------------+
+| ``'X'`` | Hex format. Outputs the number in base 16, using |
+| | upper-case letters for the digits above 9. Using the |
+| | ``'#'`` option with this type adds the prefix ``"0X"`` |
+| | to the output value. |
++---------+----------------------------------------------------------+
+| ``'n'`` | Number. This is the same as ``'d'``, except that it uses |
+| | the current locale setting to insert the appropriate |
+| | number separator characters. |
++---------+----------------------------------------------------------+
+| none | The same as ``'d'``. |
++---------+----------------------------------------------------------+
+
+Integer presentation types can also be used with character and Boolean values.
+Boolean values are formatted using textual representation, either ``true`` or
+``false``, if the presentation type is not specified.
+
+The available presentation types for floating-point values are:
+
++---------+----------------------------------------------------------+
+| Type | Meaning |
++=========+==========================================================+
+| ``'a'`` | Hexadecimal floating point format. Prints the number in |
+| | base 16 with prefix ``"0x"`` and lower-case letters for |
+| | digits above 9. Uses ``'p'`` to indicate the exponent. |
++---------+----------------------------------------------------------+
+| ``'A'`` | Same as ``'a'`` except it uses upper-case letters for |
+| | the prefix, digits above 9 and to indicate the exponent. |
++---------+----------------------------------------------------------+
+| ``'e'`` | Exponent notation. Prints the number in scientific |
+| | notation using the letter 'e' to indicate the exponent. |
++---------+----------------------------------------------------------+
+| ``'E'`` | Exponent notation. Same as ``'e'`` except it uses an |
+| | upper-case ``'E'`` as the separator character. |
++---------+----------------------------------------------------------+
+| ``'f'`` | Fixed point. Displays the number as a fixed-point |
+| | number. |
++---------+----------------------------------------------------------+
+| ``'F'`` | Fixed point. Same as ``'f'``, but converts ``nan`` to |
+| | ``NAN`` and ``inf`` to ``INF``. |
++---------+----------------------------------------------------------+
+| ``'g'`` | General format. For a given precision ``p >= 1``, |
+| | this rounds the number to ``p`` significant digits and |
+| | then formats the result in either fixed-point format |
+| | or in scientific notation, depending on its magnitude. |
+| | |
+| | A precision of ``0`` is treated as equivalent to a |
+| | precision of ``1``. |
++---------+----------------------------------------------------------+
+| ``'G'`` | General format. Same as ``'g'`` except switches to |
+| | ``'E'`` if the number gets too large. The |
+| | representations of infinity and NaN are uppercased, too. |
++---------+----------------------------------------------------------+
+| ``'n'`` | Number. This is the same as ``'g'``, except that it uses |
+| | the current locale setting to insert the appropriate |
+| | number separator characters. |
++---------+----------------------------------------------------------+
+| ``'%'`` | Fixed point as a percentage. This is similar to ``'f'``, |
+| | but the argument is multiplied by 100 and a percent sign |
+| | ``%`` is appended. |
++---------+----------------------------------------------------------+
+| none | Similar to ``'g'``, except that fixed-point notation, |
+| | when used, has at least one digit past the decimal |
+| | point. The default precision is as high as needed to |
+| | represent the particular value. |
++---------+----------------------------------------------------------+
+
+.. ifconfig:: False
+
+ +---------+----------------------------------------------------------+
+ | | The precise rules are as follows: suppose that the |
+ | | result formatted with presentation type ``'e'`` and |
+ | | precision ``p-1`` would have exponent ``exp``. Then |
+ | | if ``-4 <= exp < p``, the number is formatted |
+ | | with presentation type ``'f'`` and precision |
+ | | ``p-1-exp``. Otherwise, the number is formatted |
+ | | with presentation type ``'e'`` and precision ``p-1``. |
+ | | In both cases insignificant trailing zeros are removed |
+ | | from the significand, and the decimal point is also |
+ | | removed if there are no remaining digits following it. |
+ | | |
+ | | Positive and negative infinity, positive and negative |
+ | | zero, and nans, are formatted as ``inf``, ``-inf``, |
+ | | ``0``, ``-0`` and ``nan`` respectively, regardless of |
+ | | the precision. |
+ | | |
+ +---------+----------------------------------------------------------+
+
+The available presentation types for pointers are:
+
++---------+----------------------------------------------------------+
+| Type | Meaning |
++=========+==========================================================+
+| ``'p'`` | Pointer format. This is the default type for |
+| | pointers and may be omitted. |
++---------+----------------------------------------------------------+
+| none | The same as ``'p'``. |
++---------+----------------------------------------------------------+

+
+Format Examples
+===============
+
+This section contains examples of the format syntax and comparison with
+the printf formatting.
+
+In most of the cases the syntax is similar to the printf formatting, with the
+addition of the ``{}`` and with ``:`` used instead of ``%``.
+For example, ``"%03.2f"`` can be translated to ``"{:03.2f}"``.
+
+The new format syntax also supports new and different options, shown in the
+following examples.
+
+Accessing arguments by position::
+
+ format("{0}, {1}, {2}", 'a', 'b', 'c');
+ // Result: "a, b, c"
+ format("{}, {}, {}", 'a', 'b', 'c');
+ // Result: "a, b, c"
+ format("{2}, {1}, {0}", 'a', 'b', 'c');
+ // Result: "c, b, a"
+ format("{0}{1}{0}", "abra", "cad"); // arguments' indices can be repeated
+ // Result: "abracadabra"
+
+Aligning the text and specifying a width::
+
+ format("{:<30}", "left aligned");
+ // Result: "left aligned "
+ format("{:>30}", "right aligned");
+ // Result: " right aligned"
+ format("{:^30}", "centered");
+ // Result: " centered "
+ format("{:*^30}", "centered"); // use '*' as a fill char
+ // Result: "***********centered***********"
+
+Dynamic width::
+
+ format("{:<{}}", "left aligned", 30);
+ // Result: "left aligned "
+
+Dynamic precision::
+
+ format("{:.{}f}", 3.14, 1);
+ // Result: "3.1"
+
+Replacing ``%+f``, ``%-f``, and ``% f`` and specifying a sign::
+
+ format("{:+f}; {:+f}", 3.14, -3.14); // show it always
+ // Result: "+3.140000; -3.140000"
+ format("{: f}; {: f}", 3.14, -3.14); // show a space for positive numbers
+ // Result: " 3.140000; -3.140000"
+ format("{:-f}; {:-f}", 3.14, -3.14); // show only the minus -- same as '{:f}; {:f}'
+ // Result: "3.140000; -3.140000"
+
+As a percentage::
+
+ format("{0:f} or {0:%}", .635);
+ // Result: "0.635000 or 63.500000%"
+ format("{:*^{}.{}%}", 1., 15, 2); // With fill, dynamic width and dynamic precision.
+ // Result: "****100.00%****"
+
+Replacing ``%x`` and ``%o`` and converting the value to different bases::
+
+ format("int: {0:d}; hex: {0:x}; oct: {0:o}; bin: {0:b}", 42);
+ // Result: "int: 42; hex: 2a; oct: 52; bin: 101010"
+ // with 0x or 0 or 0b as prefix:
+ format("int: {0:d}; hex: {0:#x}; oct: {0:#o}; bin: {0:#b}", 42);
+ // Result: "int: 42; hex: 0x2a; oct: 052; bin: 0b101010"
+
+Padded hex byte with prefix and always prints both hex characters::
+
+ format("{:#04x}", 0);
+ // Result: "0x00"
+
+.. ifconfig:: False
+
+ Using the comma as a thousands separator::
+
+ format("{:,}", 1234567890);
+ '1,234,567,890'
+
+ Using type-specific formatting::
+
+ >>> import datetime
+ >>> d = datetime.datetime(2010, 7, 4, 12, 15, 58)
+ Format("{:%Y-%m-%d %H:%M:%S}") << d)
+ '2010-07-04 12:15:58'
+
+ Nesting arguments and more complex examples::
+
+ >>> for align, text in zip('<^>', ['left', 'center', 'right']):
+ ... '{0:{fill}{align}16}") << text, fill=align, align=align)
+ ...
+ 'left<<<<<<<<<<<<'
+ '^^^^^center^^^^^'
+ '>>>>>>>>>>>right'
+ >>>
+ >>> octets = [192, 168, 0, 1]
+ Format("{:02X}{:02X}{:02X}{:02X}") << *octets)
+ 'C0A80001'
+ >>> int(_, 16)
+ 3232235521
+ >>>
+ >>> width = 5
+ >>> for num in range(5,12):
+ ... for base in 'dXob':
+ ... print('{0:{width}{base}}") << num, base=base, width=width), end=' ')
+ ... print()
+ ...
+ 5 5 5 101
+ 6 6 6 110
+ 7 7 7 111
+ 8 8 10 1000
+ 9 9 11 1001
+ 10 A 12 1010
+ 11 B 13 1011

+*****
+Usage
+*****
+
+To use the {fmt} library, add :file:`fmt/core.h`, :file:`fmt/format.h`,
+:file:`fmt/format-inl.h`, :file:`src/format.cc` and optionally other headers
+from a `release archive <https://github.com/fmtlib/fmt/releases/latest>`_ or
+the `Git repository <https://github.com/fmtlib/fmt>`_ to your project.
+Alternatively, you can :ref:`build the library with CMake <building>`.
+
+.. _building:
+
+Building the Library
+====================
+
+The included `CMake build script`__ can be used to build the fmt
+library on a wide range of platforms. CMake is freely available for
+download from http://www.cmake.org/download/.
+
+__ https://github.com/fmtlib/fmt/blob/master/CMakeLists.txt
+
+CMake works by generating native makefiles or project files that can
+be used in the compiler environment of your choice. The typical
+workflow starts with::
+
+ mkdir build # Create a directory to hold the build output.
+ cd build
+ cmake .. # Generate native build scripts.
+
+where :file:`{<path/to/fmt>}` is a path to the ``fmt`` repository.
+
+If you are on a \*nix system, you should now see a Makefile in the
+current directory. Now you can build the library by running :command:`make`.
+
+Once the library has been built you can invoke :command:`make test` to run
+the tests.
+
+You can control generation of the make ``test`` target with the ``FMT_TEST``
+CMake option. This can be useful if you include fmt as a subdirectory in
+your project but don't want to add fmt's tests to your ``test`` target.
+
+If you use Windows and have Visual Studio installed, a :file:`FMT.sln`
+file and several :file:`.vcproj` files will be created. You can then build them
+using Visual Studio or msbuild.
+
+On Mac OS X with Xcode installed, an :file:`.xcodeproj` file will be generated.
+
+To build a `shared library`__ set the ``BUILD_SHARED_LIBS`` CMake variable to
+``TRUE``::
+
+ cmake -DBUILD_SHARED_LIBS=TRUE ...
+
+__ http://en.wikipedia.org/wiki/Library_%28computing%29#Shared_libraries
+
+Installing the Library
+======================
+
+After building the library you can install it on a Unix-like system by running
+:command:`sudo make install`.
+
+Usage with CMake
+================
+
+You can add the ``fmt`` library directory into your project and include it in
+your ``CMakeLists.txt`` file::
+
+ add_subdirectory(fmt)
+
+or
+
+::
+
+ add_subdirectory(fmt EXCLUDE_FROM_ALL)
+
+to exclude it from ``make``, ``make all``, or ``cmake --build .``.
+
+You can detect and use an installed version of {fmt} as follows::
+
+ find_package(fmt)
+ target_link_libraries(<your-target> fmt::fmt)
+
+Setting up your target to use a header-only version of ``fmt`` is equally easy::
+
+ target_link_libraries(<your-target> PRIVATE fmt::fmt-header-only)
+
+Building the Documentation
+==========================
+
+To build the documentation you need the following software installed on your
+system:
+
+* `Python <https://www.python.org/>`_ with pip and virtualenv
+* `Doxygen <http://www.stack.nl/~dimitri/doxygen/>`_
+* `Less <http://lesscss.org/>`_ with ``less-plugin-clean-css``.
+ Ubuntu doesn't package the ``clean-css`` plugin so you should use ``npm``
+ instead of ``apt`` to install both ``less`` and the plugin::
+
+ sudo npm install -g less less-plugin-clean-css.
+
+First generate makefiles or project files using CMake as described in
+the previous section. Then compile the ``doc`` target/project, for example::
+
+ make doc
+
+This will generate the HTML documentation in ``doc/html``.
+
+Android NDK
+===========
+
+fmt provides `Android.mk file`__ that can be used to build the library
+with `Android NDK <https://developer.android.com/tools/sdk/ndk/index.html>`_.
+For an example of using fmt with Android NDK, see the
+`android-ndk-example <https://github.com/fmtlib/android-ndk-example>`_
+repository.
+
+__ https://github.com/fmtlib/fmt/blob/master/Android.mk
+
+Homebrew
+========
+
+fmt can be installed on OS X using `Homebrew <http://brew.sh/>`_::
+
+ brew install fmt

+in fmt. It is a part of the continous fuzzing at
+[oss-fuzz](https://github.com/google/oss-fuzz).
+
+The source code is modified to make the fuzzing possible without locking up on
+resource exhaustion:
+```cpp
+#ifdef FUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION
+if(spec.precision>100000) {
+ throw std::runtime_error("fuzz mode - avoiding large precision");
+}
+#endif
+```
+This macro is the defacto standard for making fuzzing practically possible, see
+[the libFuzzer documentation](https://llvm.org/docs/LibFuzzer.html#fuzzer-friendly-build-mode).
+
+## Running the fuzzers locally
+
+There is a [helper script](build.sh) to build the fuzzers, which has only been
+tested on Debian and Ubuntu linux so far. There should be no problems fuzzing on
+Windows (using clang>=8) or on Mac, but the script will probably not work out of
+the box.
+
+Something along
+```sh
+mkdir build
+cd build
+export CXX=clang++
+export CXXFLAGS="-fsanitize=fuzzer-no-link -DFUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION= -g"
+cmake .. -DFMT_SAFE_DURATION_CAST=On -DFMT_FUZZ=On -DFMT_FUZZ_LINKMAIN=Off -DFMT_FUZZ_LDFLAGS="-fsanitize=fuzzer"
+cmake --build .
+```
+should work to build the fuzzers for all platforms which clang supports.
+
+Execute a fuzzer with for instance
+```sh
+cd build
+export UBSAN_OPTIONS=halt_on_error=1
+mkdir out_chrono
+bin/fuzzer_chrono_duration out_chrono
+```

+// 0 and it is destroyed, preventing the child from acquiring it. The
+// parent now has to release it, or read operations on the read end of
+// the pipe will not return when the child terminates.
+// 5. The parent reads child's output through the pipe (outcome code and
+// any possible error messages) from the pipe, and its stderr and then

+// bipartite matching. Flow is considered to be from left to right.
+// There is an implicit source node that is connected to all of the left
+// nodes, and an implicit sink node that is connected to all of the
+// right nodes. All edges have unit capacity.
+//
+// Neither the flow graph nor the residual flow graph are represented
+// explicitly. Instead, they are implied by the information in 'graph' and
+// a vector<int> called 'left_' whose elements are initialized to the
+// value kUnused. This represents the initial state of the algorithm,
+// where the flow graph is empty, and the residual flow graph has the
+// following edges:
+// - An edge from source to each left_ node
+// - An edge from each right_ node to sink
+// - An edge from each left_ node to each right_ node, if the
+// corresponding edge exists in 'graph'.
+//
+// When the TryAugment() method adds a flow, it sets left_[l] = r for some
+// nodes l and r. This induces the following changes:
+// - The edges (source, l), (l, r), and (r, sink) are added to the
+// flow graph.
+// - The same three edges are removed from the residual flow graph.
+// - The reverse edges (l, source), (r, l), and (sink, r) are added
+// to the residual flow graph, which is a directional graph
+// representing unused flow capacity.
+//
+// When the method augments a flow (moving left_[l] from some r1 to some
+// other r2), this can be thought of as "undoing" the above steps with
+// respect to r1 and "redoing" them with respect to r2.
+//
+// It bears repeating that the flow graph and residual flow graph are
+// never represented explicitly, but can be derived by looking at the
+// information in 'graph' and in left_.
+//
+// As an optimization, there is a second vector<int> called right_ which
+// does not provide any new information. Instead, it enables more
+// efficient queries about edges entering or leaving the right-side nodes
+// of the flow or residual flow graphs. The following invariants are
+// maintained:

+// The ACTION* family of macros can be used in a namespace scope to
+// define custom actions easily. The syntax:
+//
+// ACTION(name) { statements; }
+//
+// will define an action with the given name that executes the
+// statements. The value returned by the statements will be used as
+// the return value of the action. Inside the statements, you can
+// refer to the K-th (0-based) argument of the mock function by
+// 'argK', and refer to its type by 'argK_type'. For example:
+//
+// ACTION(IncrementArg1) {
+// arg1_type temp = arg1;
+// return ++(*temp);
+// }
+//
+// allows you to write
+//
+// ...WillOnce(IncrementArg1());
+//
+// You can also refer to the entire argument tuple and its type by
+// 'args' and 'args_type', and refer to the mock function type and its
+// return type by 'function_type' and 'return_type'.
+//
+// Note that you don't need to specify the types of the mock function
+// arguments. However rest assured that your code is still type-safe:
+// you'll get a compiler error if *arg1 doesn't support the ++
+// operator, or if the type of ++(*arg1) isn't compatible with the
+// mock function's return type, for example.
+//
+// Sometimes you'll want to parameterize the action. For that you can use
+// another macro:
+//
+// ACTION_P(name, param_name) { statements; }
+//
+// For example:
+//
+// ACTION_P(Add, n) { return arg0 + n; }
+//
+// will allow you to write:
+//
+// ...WillOnce(Add(5));
+//
+// Note that you don't need to provide the type of the parameter
+// either. If you need to reference the type of a parameter named
+// 'foo', you can write 'foo_type'. For example, in the body of
+// ACTION_P(Add, n) above, you can write 'n_type' to refer to the type
+// of 'n'.
+//
+// We also provide ACTION_P2, ACTION_P3, ..., up to ACTION_P10 to support
+// multi-parameter actions.
+//
+// For the purpose of typing, you can view
+//
+// ACTION_Pk(Foo, p1, ..., pk) { ... }
+//
+// as shorthand for
+//
+// template <typename p1_type, ..., typename pk_type>
+// FooActionPk<p1_type, ..., pk_type> Foo(p1_type p1, ..., pk_type pk) { ... }
+//
+// In particular, you can provide the template type arguments
+// explicitly when invoking Foo(), as in Foo<long, bool>(5, false);
+// although usually you can rely on the compiler to infer the types
+// for you automatically. You can assign the result of expression
+// Foo(p1, ..., pk) to a variable of type FooActionPk<p1_type, ...,
+// pk_type>. This can be useful when composing actions.
+//
+// You can also overload actions with different numbers of parameters:
+//
+// ACTION_P(Plus, a) { ... }
+// ACTION_P2(Plus, a, b) { ... }
+//
+// While it's tempting to always use the ACTION* macros when defining
+// a new action, you should also consider implementing ActionInterface
+// or using MakePolymorphicAction() instead, especially if you need to
+// use the action a lot. While these approaches require more work,
+// they give you more control on the types of the mock function
+// arguments and the action parameters, which in general leads to
+// better compiler error messages that pay off in the long run. They
+// also allow overloading actions based on parameter types (as opposed
+// to just based on the number of parameters).
+//
+// CAVEAT:
+//
+// ACTION*() can only be used in a namespace scope. The reason is
+// that C++ doesn't yet allow function-local types to be used to
+// instantiate templates. The up-coming C++0x standard will fix this.
+// Once that's done, we'll consider supporting using ACTION*() inside
+// a function.

+// an integral constant, or a template. p_i is the name of the i-th
+// value parameter.
+//
+// Example:
+//
+// // DuplicateArg<k, T>(output) converts the k-th argument of the mock
+// // function to type T and copies it to *output.
+// ACTION_TEMPLATE(DuplicateArg,
+// HAS_2_TEMPLATE_PARAMS(int, k, typename, T),

+// }
+// ...
+// int n;
+// EXPECT_CALL(mock, Foo(_, _))
+// .WillOnce(DuplicateArg<1, unsigned char>(&n));
+//
+// To create an instance of an action template, write:
+//
+// ActionName<t1, ..., t_m>(v1, ..., v_n)
+//
+// where the ts are the template arguments and the vs are the value
+// arguments. The value argument types are inferred by the compiler.
+// If you want to explicitly specify the value argument types, you can
+// provide additional template arguments:
+//
+// ActionName<t1, ..., t_m, u1, ..., u_k>(v1, ..., v_n)
+//
+// where u_i is the desired type of v_i.
+//
+// ACTION_TEMPLATE and ACTION/ACTION_P* can be overloaded on the
+// number of value parameters, but not on the number of template
+// parameters. Without the restriction, the meaning of the following
+// is unclear:
+//
+// OverloadedAction<int, bool>(x);
+//
+// Are we using a single-template-parameter action where 'bool' refers

+//
+// Implementation notes:

+// GMOCK_INTERNAL_*_HAS_m_TEMPLATE_PARAMS and

+// (0-based) argument, which must be a k-ary callable, of the mock

+//
+// Notes:
+//
+// 1. The arguments are passed by value by default. If you need to
+// pass an argument by reference, wrap it inside ByRef(). For
+// example,
+//
+// InvokeArgument<1>(5, string("Hello"), ByRef(foo))
+//
+// passes 5 and string("Hello") by value, and passes foo by
+// reference.
+//
+// 2. If the callable takes an argument by reference but ByRef() is
+// not used, it will receive the reference to a copy of the value,
+// instead of the original value. For example, when the 0-th
+// argument of the mock function takes a const string&, the action
+//
+// InvokeArgument<0>(string("Hello"))
+//
+// makes a copy of the temporary string("Hello") object and passes a
+// reference of the copy, instead of the original temporary object,
+// to the callable. This makes it easy for a user to define an
+// InvokeArgument action from temporary values and have it performed
+// later.

+// A MockFunction<F> class has one mock method whose type is F. It is
+// useful when you just want your test code to emit some messages and
+// have Google Mock verify the right messages are sent (and perhaps at
+// the right times). For example, if you are exercising code:
+//
+// Foo(1);
+// Foo(2);
+// Foo(3);
+//
+// and want to verify that Foo(1) and Foo(3) both invoke
+// mock.Bar("a"), but Foo(2) doesn't invoke anything, you can write:
+//
+// TEST(FooTest, InvokesBarCorrectly) {
+// MyMock mock;
+// MockFunction<void(string check_point_name)> check;
+// {
+// InSequence s;
+//
+// EXPECT_CALL(mock, Bar("a"));
+// EXPECT_CALL(check, Call("1"));
+// EXPECT_CALL(check, Call("2"));
+// EXPECT_CALL(mock, Bar("a"));
+// }
+// Foo(1);
+// check.Call("1");
+// Foo(2);
+// check.Call("2");
+// Foo(3);
+// }
+//
+// The expectation spec says that the first Bar("a") must happen
+// before check point "1", the second Bar("a") must happen after check
+// point "2", and nothing should happen between the two check
+// points. The explicit check points make it easy to tell which
+// Bar("a") is called by which call to Foo().

+// Implements class templates NiceMock, NaggyMock, and StrictMock.
+//
+// Given a mock class MockFoo that is created using Google Mock,
+// NiceMock<MockFoo> is a subclass of MockFoo that allows
+// uninteresting calls (i.e. calls to mock methods that have no
+// EXPECT_CALL specs), NaggyMock<MockFoo> is a subclass of MockFoo
+// that prints a warning when an uninteresting call occurs, and
+// StrictMock<MockFoo> is a subclass of MockFoo that treats all
+// uninteresting calls as errors.
+//
+// Currently a mock is naggy by default, so MockFoo and
+// NaggyMock<MockFoo> behave like the same. However, we will soon
+// switch the default behavior of mocks to be nice, as that in general
+// leads to more maintainable tests. When that happens, MockFoo will
+// stop behaving like NaggyMock<MockFoo> and start behaving like
+// NiceMock<MockFoo>.
+//
+// NiceMock, NaggyMock, and StrictMock "inherit" the constructors of
+// their respective base class, with up-to 10 arguments. Therefore
+// you can write NiceMock<MockFoo>(5, "a") to construct a nice mock
+// where MockFoo has a constructor that accepts (int, const char*),
+// for example.
+//
+// A known limitation is that NiceMock<MockFoo>, NaggyMock<MockFoo>,
+// and StrictMock<MockFoo> only works for mock methods defined using
+// the MOCK_METHOD* family of macros DIRECTLY in the MockFoo class.
+// If a mock method is defined in a base class of MockFoo, the "nice"
+// or "strict" modifier may not affect it, depending on the compiler.
+// In particular, nesting NiceMock, NaggyMock, and StrictMock is NOT
+// supported.
+//
+// Another known limitation is that the constructors of the base mock
+// cannot have arguments passed by non-const reference, which are
+// banned by the Google C++ style guide anyway.

+
+
+// The MATCHER* family of macros can be used in a namespace scope to
+// define custom matchers easily.
+//
+// Basic Usage
+// ===========
+//
+// The syntax
+//
+// MATCHER(name, description_string) { statements; }
+//
+// defines a matcher with the given name that executes the statements,
+// which must return a bool to indicate if the match succeeds. Inside
+// the statements, you can refer to the value being matched by 'arg',
+// and refer to its type by 'arg_type'.
+//
+// The description string documents what the matcher does, and is used
+// to generate the failure message when the match fails. Since a
+// MATCHER() is usually defined in a header file shared by multiple
+// C++ source files, we require the description to be a C-string
+// literal to avoid possible side effects. It can be empty, in which
+// case we'll use the sequence of words in the matcher name as the
+// description.
+//
+// For example:
+//
+// MATCHER(IsEven, "") { return (arg % 2) == 0; }
+//
+// allows you to write
+//
+// // Expects mock_foo.Bar(n) to be called where n is even.
+// EXPECT_CALL(mock_foo, Bar(IsEven()));
+//
+// or,
+//
+// // Verifies that the value of some_expression is even.
+// EXPECT_THAT(some_expression, IsEven());
+//
+// If the above assertion fails, it will print something like:
+//
+// Value of: some_expression
+// Expected: is even
+// Actual: 7
+//
+// where the description "is even" is automatically calculated from the
+// matcher name IsEven.
+//
+// Argument Type
+// =============
+//
+// Note that the type of the value being matched (arg_type) is
+// determined by the context in which you use the matcher and is
+// supplied to you by the compiler, so you don't need to worry about
+// declaring it (nor can you). This allows the matcher to be
+// polymorphic. For example, IsEven() can be used to match any type
+// where the value of "(arg % 2) == 0" can be implicitly converted to
+// a bool. In the "Bar(IsEven())" example above, if method Bar()
+// takes an int, 'arg_type' will be int; if it takes an unsigned long,
+// 'arg_type' will be unsigned long; and so on.
+//
+// Parameterizing Matchers
+// =======================
+//
+// Sometimes you'll want to parameterize the matcher. For that you
+// can use another macro:
+//
+// MATCHER_P(name, param_name, description_string) { statements; }
+//
+// For example:
+//
+// MATCHER_P(HasAbsoluteValue, value, "") { return abs(arg) == value; }
+//
+// will allow you to write:
+//
+// EXPECT_THAT(Blah("a"), HasAbsoluteValue(n));
+//
+// which may lead to this message (assuming n is 10):
+//
+// Value of: Blah("a")
+// Expected: has absolute value 10
+// Actual: -9
+//
+// Note that both the matcher description and its parameter are
+// printed, making the message human-friendly.
+//
+// In the matcher definition body, you can write 'foo_type' to
+// reference the type of a parameter named 'foo'. For example, in the
+// body of MATCHER_P(HasAbsoluteValue, value) above, you can write
+// 'value_type' to refer to the type of 'value'.
+//
+// We also provide MATCHER_P2, MATCHER_P3, ..., up to MATCHER_P10 to
+// support multi-parameter matchers.
+//
+// Describing Parameterized Matchers
+// =================================
+//
+// The last argument to MATCHER*() is a string-typed expression. The
+// expression can reference all of the matcher's parameters and a
+// special bool-typed variable named 'negation'. When 'negation' is
+// false, the expression should evaluate to the matcher's description;
+// otherwise it should evaluate to the description of the negation of
+// the matcher. For example,
+//
+// using testing::PrintToString;
+//
+// MATCHER_P2(InClosedRange, low, hi,
+// string(negation ? "is not" : "is") + " in range [" +
+// PrintToString(low) + ", " + PrintToString(hi) + "]") {
+// return low <= arg && arg <= hi;
+// }
+// ...
+// EXPECT_THAT(3, InClosedRange(4, 6));
+// EXPECT_THAT(3, Not(InClosedRange(2, 4)));
+//
+// would generate two failures that contain the text:
+//
+// Expected: is in range [4, 6]
+// ...
+// Expected: is not in range [2, 4]
+//
+// If you specify "" as the description, the failure message will
+// contain the sequence of words in the matcher name followed by the
+// parameter values printed as a tuple. For example,
+//
+// MATCHER_P2(InClosedRange, low, hi, "") { ... }
+// ...
+// EXPECT_THAT(3, InClosedRange(4, 6));
+// EXPECT_THAT(3, Not(InClosedRange(2, 4)));
+//
+// would generate two failures that contain the text:
+//
+// Expected: in closed range (4, 6)
+// ...
+// Expected: not (in closed range (2, 4))
+//
+// Types of Matcher Parameters
+// ===========================
+//
+// For the purpose of typing, you can view
+//
+// MATCHER_Pk(Foo, p1, ..., pk, description_string) { ... }
+//
+// as shorthand for
+//
+// template <typename p1_type, ..., typename pk_type>
+// FooMatcherPk<p1_type, ..., pk_type>
+// Foo(p1_type p1, ..., pk_type pk) { ... }
+//
+// When you write Foo(v1, ..., vk), the compiler infers the types of
+// the parameters v1, ..., and vk for you. If you are not happy with
+// the result of the type inference, you can specify the types by
+// explicitly instantiating the template, as in Foo<long, bool>(5,
+// false). As said earlier, you don't get to (or need to) specify
+// 'arg_type' as that's determined by the context in which the matcher
+// is used. You can assign the result of expression Foo(p1, ..., pk)
+// to a variable of type FooMatcherPk<p1_type, ..., pk_type>. This
+// can be useful when composing matchers.
+//
+// While you can instantiate a matcher template with reference types,
+// passing the parameters by pointer usually makes your code more
+// readable. If, however, you still want to pass a parameter by
+// reference, be aware that in the failure message generated by the
+// matcher you will see the value of the referenced object but not its
+// address.
+//
+// Explaining Match Results
+// ========================
+//
+// Sometimes the matcher description alone isn't enough to explain why
+// the match has failed or succeeded. For example, when expecting a
+// long string, it can be very helpful to also print the diff between
+// the expected string and the actual one. To achieve that, you can
+// optionally stream additional information to a special variable
+// named result_listener, whose type is a pointer to class
+// MatchResultListener:
+//
+// MATCHER_P(EqualsLongString, str, "") {
+// if (arg == str) return true;
+//
+// *result_listener << "the difference: "
+/// << DiffStrings(str, arg);
+// return false;
+// }
+//
+// Overloading Matchers
+// ====================
+//
+// You can overload matchers with different numbers of parameters:
+//
+// MATCHER_P(Blah, a, description_string1) { ... }
+// MATCHER_P2(Blah, a, b, description_string2) { ... }
+//
+// Caveats
+// =======
+//
+// When defining a new matcher, you should also consider implementing
+// MatcherInterface or using MakePolymorphicMatcher(). These
+// approaches require more work than the MATCHER* macros, but also
+// give you more control on the types of the value being matched and
+// the matcher parameters, which may leads to better compiler error
+// messages when the matcher is used wrong. They also allow
+// overloading matchers based on parameter types (as opposed to just
+// based on the number of parameters).
+//
+// MATCHER*() can only be used in a namespace scope. The reason is
+// that C++ doesn't yet allow function-local types to be used to
+// instantiate templates. The up-coming C++0x standard will fix this.
+// Once that's done, we'll consider supporting using MATCHER*() inside
+// a function.
+//
+// More Information
+// ================

+// GTEST_HAS_EXCEPTIONS - Define it to 1/0 to indicate that exceptions
+// are enabled.
+// GTEST_HAS_GLOBAL_STRING - Define it to 1/0 to indicate that ::string
+// is/isn't available (some systems define
+// ::string, which is different to std::string).
+// GTEST_HAS_GLOBAL_WSTRING - Define it to 1/0 to indicate that ::string
+// is/isn't available (some systems define

+// Google Test as a shared library (known as
+// DLL on Windows).
+// GTEST_CREATE_SHARED_LIBRARY
+// - Define to 1 when compiling Google Test itself
+// as a shared library.
+
+// This header defines the following utilities:

+//
+// Template meta programming:
+// is_pointer - as in TR1; needed on Symbian and IBM XL C/C++ only.

+// regex - A regex that a macro such as EXPECT_DEATH would use to test

+// compiled but not evaluated by this macro, to ensure that
+// this macro only accepts expressions that a macro such as
+// EXPECT_DEATH would accept.

+//
+// 1. It generates a warning if there is more than one active
+// thread. This is because it's safe to fork() or clone() only
+// when there is a single thread.
+//
+// 2. The parent process clone()s a sub-process and runs the death
+// test in it; the sub-process exits with code 0 at the end of the
+// death test, if it hasn't exited already.
+//
+// 3. The parent process waits for the sub-process to terminate.
+//
+// 4. The parent process checks the exit code and error message of
+// the sub-process.
+//
+// Examples:
+//
+// ASSERT_DEATH(server.SendMessage(56, "Hello"), "Invalid port number");
+// for (int i = 0; i < 5; i++) {
+// EXPECT_DEATH(server.ProcessRequest(i),
+// "Invalid request .* in ProcessRequest()")
+// << "Failed to die on request " << i;
+// }
+//
+// ASSERT_EXIT(server.ExitNow(), ::testing::ExitedWithCode(0), "Exiting");
+//
+// bool KilledBySIGHUP(int exit_code) {
+// return WIFSIGNALED(exit_code) && WTERMSIG(exit_code) == SIGHUP;
+// }
+//
+// ASSERT_EXIT(client.HangUpServer(), KilledBySIGHUP, "Hanging up!");
+//
+// On the regular expressions used in death tests:
+//
+// On POSIX-compliant systems (*nix), we use the <regex.h> library,
+// which uses the POSIX extended regex syntax.
+//
+// On other platforms (e.g. Windows), we only support a simple regex
+// syntax implemented as part of Google Test. This limited
+// implementation should be enough most of the time when writing
+// death tests; though it lacks many features you can find in PCRE
+// or POSIX extended regex syntax. For example, we don't support
+// union ("x|y"), grouping ("(xy)"), brackets ("[xy]"), and
+// repetition count ("x{5,7}"), among others.
+//
+// Below is the syntax that we do support. We chose it to be a
+// subset of both PCRE and POSIX extended regex, so it's easy to
+// learn wherever you come from. In the following: 'A' denotes a
+// literal character, period (.), or a single \\ escape sequence;
+// 'x' and 'y' denote regular expressions; 'm' and 'n' are for
+// natural numbers.
+//
+// c matches any literal character c
+// \\d matches any decimal digit
+// \\D matches any character that's not a decimal digit
+// \\f matches \f
+// \\n matches \n
+// \\r matches \r
+// \\s matches any ASCII whitespace, including \n
+// \\S matches any character that's not a whitespace
+// \\t matches \t
+// \\v matches \v
+// \\w matches any letter, _, or decimal digit
+// \\W matches any character that \\w doesn't match
+// \\c matches any literal character c, which must be a punctuation
+// . matches any single character except \n
+// A? matches 0 or 1 occurrences of A
+// A* matches 0 or many occurrences of A
+// A+ matches 1 or many occurrences of A
+// ^ matches the beginning of a string (not that of each line)
+// $ matches the end of a string (not that of each line)
+// xy matches x followed by y
+//
+// If you accidentally use PCRE or POSIX extended regex features
+// not implemented by us, you will get a run-time failure. In that
+// case, please try to rewrite your regular expression within the
+// above syntax.
+//
+// This implementation is *not* meant to be as highly tuned or robust
+// as a compiled regex library, but should perform well enough for a
+// death test, which already incurs significant overhead by launching
+// a child process.
+//
+// Known caveats:
+//
+// A "threadsafe" style death test obtains the path to the test
+// program from argv[0] and re-executes it in the sub-process. For
+// simplicity, the current implementation doesn't search the PATH
+// when launching the sub-process. This means that the user must
+// invoke the test program via a path that contains at least one
+// path separator (e.g. path/to/foo_test and
+// /absolute/path/to/bar_test are fine, but foo_test is not). This
+// is rarely a problem as people usually don't put the test binary
+// directory in PATH.

+// Value-parameterized tests allow you to test your code with different
+// parameters without writing multiple copies of the same test.
+//
+// Here is how you use value-parameterized tests:
+
+#if 0
+
+// To write value-parameterized tests, first you should define a fixture
+// class. It is usually derived from testing::TestWithParam<T> (see below for
+// another inheritance scheme that's sometimes useful in more complicated
+// class hierarchies), where the type of your parameter values.
+// TestWithParam<T> is itself derived from testing::Test. T can be any
+// copyable type. If it's a raw pointer, you are responsible for managing the
+// lifespan of the pointed values.
+
+class FooTest : public ::testing::TestWithParam<const char*> {
+ // You can implement all the usual class fixture members here.
+};
+
+// Then, use the TEST_P macro to define as many parameterized tests
+// for this fixture as you want. The _P suffix is for "parameterized"
+// or "pattern", whichever you prefer to think.
+
+TEST_P(FooTest, DoesBlah) {
+ // Inside a test, access the test parameter with the GetParam() method
+ // of the TestWithParam<T> class:
+ EXPECT_TRUE(foo.Blah(GetParam()));
+ ...
+}
+
+TEST_P(FooTest, HasBlahBlah) {
+ ...
+}
+
+// Finally, you can use INSTANTIATE_TEST_CASE_P to instantiate the test
+// case with any set of parameters you want. Google Test defines a number
+// of functions for generating test parameters. They return what we call
+// (surprise!) parameter generators. Here is a summary of them, which
+// are all in the testing namespace:
+//
+//
+// Range(begin, end [, step]) - Yields values {begin, begin+step,
+// begin+step+step, ...}. The values do not
+// include end. step defaults to 1.
+// Values(v1, v2, ..., vN) - Yields values {v1, v2, ..., vN}.
+// ValuesIn(container) - Yields values from a C-style array, an STL
+// ValuesIn(begin,end) container, or an iterator range [begin, end).
+// Bool() - Yields sequence {false, true}.
+// Combine(g1, g2, ..., gN) - Yields all combinations (the Cartesian product
+// for the math savvy) of the values generated
+// by the N generators.
+//
+// For more details, see comments at the definitions of these functions below
+// in this file.
+//
+// The following statement will instantiate tests from the FooTest test case
+// each with parameter values "meeny", "miny", and "moe".
+
+INSTANTIATE_TEST_CASE_P(InstantiationName,
+ FooTest,
+ Values("meeny", "miny", "moe"));
+
+// To distinguish different instances of the pattern, (yes, you
+// can instantiate it more then once) the first argument to the
+// INSTANTIATE_TEST_CASE_P macro is a prefix that will be added to the
+// actual test case name. Remember to pick unique prefixes for different
+// instantiations. The tests from the instantiation above will have
+// these names:
+//
+// * InstantiationName/FooTest.DoesBlah/0 for "meeny"
+// * InstantiationName/FooTest.DoesBlah/1 for "miny"
+// * InstantiationName/FooTest.DoesBlah/2 for "moe"
+// * InstantiationName/FooTest.HasBlahBlah/0 for "meeny"
+// * InstantiationName/FooTest.HasBlahBlah/1 for "miny"
+// * InstantiationName/FooTest.HasBlahBlah/2 for "moe"
+//
+// You can use these names in --gtest_filter.
+//
+// This statement will instantiate all tests from FooTest again, each
+// with parameter values "cat" and "dog":
+
+const char* pets[] = {"cat", "dog"};
+INSTANTIATE_TEST_CASE_P(AnotherInstantiationName, FooTest, ValuesIn(pets));
+
+// The tests from the instantiation above will have these names:
+//
+// * AnotherInstantiationName/FooTest.DoesBlah/0 for "cat"
+// * AnotherInstantiationName/FooTest.DoesBlah/1 for "dog"
+// * AnotherInstantiationName/FooTest.HasBlahBlah/0 for "cat"
+// * AnotherInstantiationName/FooTest.HasBlahBlah/1 for "dog"
+//
+// Please note that INSTANTIATE_TEST_CASE_P will instantiate all tests
+// in the given test case, whether their definitions come before or
+// AFTER the INSTANTIATE_TEST_CASE_P statement.
+//
+// Please also note that generator expressions (including parameters to the
+// generators) are evaluated in InitGoogleTest(), after main() has started.
+// This allows the user on one hand, to adjust generator parameters in order
+// to dynamically determine a set of tests to run and on the other hand,
+// give the user a chance to inspect the generated tests with Google Test
+// reflection API before RUN_ALL_TESTS() is executed.
+//
+// You can see samples/sample7_unittest.cc and samples/sample8_unittest.cc
+// for more examples.
+//
+// In the future, we plan to publish the API for defining new parameter
+// generators. But for now this interface remains part of the internal
+// implementation and is subject to change.
+//
+//
+// A parameterized test fixture must be derived from testing::Test and from
+// testing::WithParamInterface<T>, where T is the type of the parameter
+// values. Inheriting from TestWithParam<T> satisfies that requirement because
+// TestWithParam<T> inherits from both Test and WithParamInterface. In more
+// complicated hierarchies, however, it is occasionally useful to inherit
+// separately from Test and WithParamInterface. For example:
+
+class BaseTest : public ::testing::Test {
+ // You can inherit all the usual members for a non-parameterized test
+ // fixture here.
+};
+
+class DerivedTest : public BaseTest, public ::testing::WithParamInterface<int> {
+ // The usual test fixture members go here too.
+};
+
+TEST_F(BaseTest, HasFoo) {
+ // This is an ordinary non-parameterized test.
+}
+
+TEST_P(DerivedTest, DoesBlah) {
+ // GetParam works just the same here as if you inherit from TestWithParam.
+ EXPECT_TRUE(foo.Blah(GetParam()));

+// A "smart" pointer type with reference tracking. Every pointer to a
+// particular object is kept on a circular linked list. When the last pointer
+// to an object is destroyed or reassigned, the object is deleted.
+//
+// Used properly, this deletes the object when the last reference goes away.
+// There are several caveats:
+// - Like all reference counting schemes, cycles lead to leaks.
+// - Each smart pointer is actually two pointers (8 bytes instead of 4).
+// - Every time a pointer is assigned, the entire list of pointers to that
+// object is traversed. This class is therefore NOT SUITABLE when there
+// will often be more than two or three pointers to a particular object.
+// - References are only tracked as long as linked_ptr<> objects are copied.
+// If a linked_ptr<> is converted to a raw pointer and back, BAD THINGS
+// will happen (double deletion).
+//
+// A good use of this class is storing object references in STL containers.
+// You can safely put linked_ptr<> in a vector<>.
+// Other uses may not be as good.
+//
+// Note: If you use an incomplete type with linked_ptr<>, the class
+// *containing* linked_ptr<> must have a constructor and destructor (even
+// if they do nothing!).
+//
+// Bill Gibbons suggested we use something like this.
+//
+// Thread Safety:
+// Unlike other linked_ptr implementations, in this implementation
+// a linked_ptr object is thread-safe in the sense that:
+// - it's safe to copy linked_ptr objects concurrently,
+// - it's safe to copy *from* a linked_ptr and read its underlying
+// raw pointer (e.g. via get()) concurrently, and
+// - it's safe to write to two linked_ptrs that point to the same
+// shared object concurrently.
+// TODO(wan@google.com): rename this to safe_linked_ptr to avoid
+// confusion with normal linked_ptr.

+// This file implements a universal value printer that can print a
+// value of any type T:
+//
+// void ::testing::internal::UniversalPrinter<T>::Print(value, ostream_ptr);
+//
+// A user can teach this function how to print a class type T by
+// defining either operator<<() or PrintTo() in the namespace that
+// defines T. More specifically, the FIRST defined function in the
+// following list will be used (assuming T is defined in namespace
+// foo):
+//
+// 1. foo::PrintTo(const T&, ostream*)
+// 2. operator<<(ostream&, const T&) defined in either foo or the
+// global namespace.
+//
+// If none of the above is defined, it will print the debug string of
+// the value if it is a protocol buffer, or print the raw bytes in the
+// value otherwise.
+//
+// To aid debugging: when T is a reference type, the address of the
+// value is also printed; when T is a (const) char pointer, both the
+// pointer value and the NUL-terminated string it points to are
+// printed.
+//
+// We also provide some convenient wrappers:
+//
+// // Prints a value to a string. For a (const or not) char
+// // pointer, the NUL-terminated string (but not the pointer) is
+// // printed.
+// std::string ::testing::PrintToString(const T& value);
+//
+// // Prints a value tersely: for a reference type, the referenced
+// // value (but not the address) is printed; for a (const or not) char
+// // pointer, the NUL-terminated string (but not the pointer) is
+// // printed.
+// void ::testing::internal::UniversalTersePrint(const T& value, ostream*);
+//
+// // Prints value using the type inferred by the compiler. The difference
+// // from UniversalTersePrint() is that this function prints both the
+// // pointer and the NUL-terminated string for a (const or not) char pointer.
+// void ::testing::internal::UniversalPrint(const T& value, ostream*);
+//
+// // Prints the fields of a tuple tersely to a string vector, one
+// // element for each field. Tuple support must be enabled in
+// // gtest-port.h.
+// std::vector<string> UniversalTersePrintTupleFieldsToStrings(
+// const Tuple& value);
+//
+// Known limitation:
+//
+// The print primitives print the elements of an STL-style container
+// using the compiler-inferred type of *iter where iter is a
+// const_iterator of the container. When const_iterator is an input
+// iterator but not a forward iterator, this inferred type may not
+// match value_type, and the print output may be incorrect. In
+// practice, this is rarely a problem as for most containers
+// const_iterator is a forward iterator. We'll fix this if there's an
+// actual need for it. Note that this fix cannot rely on value_type
+// being defined as many user-defined container types don't have
+// value_type.

+// Google Test uses these generators to produce parameters for value-
+// parameterized tests. When a parameterized test case is instantiated
+// with a particular generator, Google Test creates and runs tests
+// for each element in the sequence produced by the generator.
+//
+// In the following sample, tests from test case FooTest are instantiated
+// each three times with parameter values 3, 5, and 8:
+//
+// class FooTest : public TestWithParam<int> { ... };
+//
+// TEST_P(FooTest, TestThis) {

+// }

+
+// Range() returns generators providing sequences of values in a range.
+//
+// Synopsis:
+// Range(start, end)
+// - returns a generator producing a sequence of values {start, start+1,
+// start+2, ..., }.
+// Range(start, end, step)
+// - returns a generator producing a sequence of values {start, start+step,
+// start+step+step, ..., }.
+// Notes:
+// * The generated sequences never include end. For example, Range(1, 5)
+// returns a generator producing a sequence {1, 2, 3, 4}. Range(1, 9, 2)
+// returns a generator producing {1, 3, 5, 7}.
+// * start and end must have the same type. That type may be any integral or
+// floating-point type or a user defined type satisfying these conditions:
+// * It must be assignable (have operator=() defined).
+// * It must have operator+() (operator+(int-compatible type) for
+// two-operand version).
+// * It must have operator<() defined.
+// Elements in the resulting sequences will also have that type.
+// * Condition start < end must be satisfied in order for resulting sequences
+// to contain any elements.

+// - returns a generator producing sequences with elements coming from

+// Combine can have up to 10 arguments. This number is currently limited
+// by the maximum number of elements in the tuple implementation used by Google
+// Test.
+//
+// Example:
+//
+// This will instantiate tests in test case AnimalTest each one with

+// INSTANTIATE_TEST_CASE_P(AnimalVariations, AnimalTest,
+// Combine(Values("cat", "dog"),
+// Values(BLACK, WHITE)));
+//
+// This will instantiate tests in FlagDependentTest with all variations of two
+// Boolean flags:
+//
+// class FlagDependentTest
+// : public testing::TestWithParam<tuple<bool, bool> > {
+// virtual void SetUp() {
+// // Assigns external_flag_1 and external_flag_2 values from the tuple.
+// tie(external_flag_1, external_flag_2) = GetParam();

+// repeated for each type in the list. The typedef is necessary for
+// the macro to parse correctly.
+typedef testing::Types<char, int, unsigned int> MyTypes;
+TYPED_TEST_CASE(FooTest, MyTypes);
+
+// If the type list contains only one type, you can write that type
+// directly without Types<...>:
+// TYPED_TEST_CASE(FooTest, int);
+
+// Then, use TYPED_TEST() instead of TEST_F() to define as many typed
+// tests for this test case as you want.
+TYPED_TEST(FooTest, DoesBlah) {
+ // Inside a test, refer to TypeParam to get the type parameter.
+ // Since we are inside a derived class template, C++ requires use to

+ // prefix.
+ n += TestFixture::shared_;

+
+// Type-parameterized tests are abstract test patterns parameterized
+// by a type. Compared with typed tests, type-parameterized tests
+// allow you to define the test pattern without knowing what the type
+// parameters are. The defined pattern can be instantiated with
+// different types any number of times, in any number of translation
+// units.
+//
+// If you are designing an interface or concept, you can define a
+// suite of type-parameterized tests to verify properties that any
+// valid implementation of the interface/concept should have. Then,
+// each implementation can easily instantiate the test suite to verify
+// that it conforms to the requirements, without having to write
+// similar tests repeatedly. Here's an example:
+
+#if 0
+
+// First, define a fixture class template. It should be parameterized
+// by a type. Remember to derive it from testing::Test.
+template <typename T>
+class FooTest : public testing::Test {
+ ...
+};
+
+// Next, declare that you will define a type-parameterized test case
+// (the _P suffix is for "parameterized" or "pattern", whichever you
+// prefer):
+TYPED_TEST_CASE_P(FooTest);
+
+// Then, use TYPED_TEST_P() to define as many type-parameterized tests
+// for this type-parameterized test case as you want.

+ // Inside a test, refer to TypeParam to get the type parameter.
+ TypeParam n = 0;
+ ...
+}
+
+TYPED_TEST_P(FooTest, HasPropertyA) { ... }
+
+// Now the tricky part: you need to register all test patterns before
+// you can instantiate them. The first argument of the macro is the
+// test case name; the rest are the names of the tests in this test
+// case.
+REGISTER_TYPED_TEST_CASE_P(FooTest,
+ DoesBlah, HasPropertyA);
+
+// Finally, you are free to instantiate the pattern with the types you
+// want. If you put the above code in a header file, you can #include
+// it in multiple C++ source files and instantiate it multiple times.
+//

+// remembers a non-empty message that describes how it failed.
+//
+// To create an instance of this class, use one of the factory functions
+// (AssertionSuccess() and AssertionFailure()).
+//
+// This class is useful for two purposes:
+// 1. Defining predicate functions to be used with Boolean test assertions
+// EXPECT_TRUE/EXPECT_FALSE and their ASSERT_ counterparts
+// 2. Defining predicate-format functions to be
+// used with predicate assertions (ASSERT_PRED_FORMAT*, etc).
+//
+// For example, if you define IsEven predicate:
+//
+// testing::AssertionResult IsEven(int n) {
+// if ((n % 2) == 0)
+// return testing::AssertionSuccess();
+// else
+// return testing::AssertionFailure() << n << " is odd";
+// }
+//
+// Then the failed expectation EXPECT_TRUE(IsEven(Fib(5)))
+// will print the message
+//
+// Value of: IsEven(Fib(5))
+// Actual: false (5 is odd)
+// Expected: true
+//
+// instead of a more opaque
+//
+// Value of: IsEven(Fib(5))
+// Actual: false
+// Expected: true
+//
+// in case IsEven is a simple Boolean predicate.
+//
+// If you expect your predicate to be reused and want to support informative
+// messages in EXPECT_FALSE and ASSERT_FALSE (negative assertions show up
+// about half as often as positive ones in our tests), supply messages for
+// both success and failure cases:
+//
+// testing::AssertionResult IsEven(int n) {
+// if ((n % 2) == 0)
+// return testing::AssertionSuccess() << n << " is even";
+// else
+// return testing::AssertionFailure() << n << " is odd";
+// }
+//
+// Then a statement EXPECT_FALSE(IsEven(Fib(6))) will print
+//
+// Value of: IsEven(Fib(6))
+// Actual: true (8 is even)
+// Expected: false
+//
+// NB: Predicates that support negative Boolean assertions have reduced
+// performance in positive ones so be careful not to use them in tests
+// that have lots (tens of thousands) of positive Boolean assertions.
+//
+// To use this class with EXPECT_PRED_FORMAT assertions such as:
+//
+// // Verifies that Foo() returns an even number.
+// EXPECT_PRED_FORMAT1(IsEven, Foo());
+//
+// you need to define:
+//
+// testing::AssertionResult IsEven(const char* expr, int n) {
+// if ((n % 2) == 0)
+// return testing::AssertionSuccess();
+// else
+// return testing::AssertionFailure()
+// << "Expected: " << expr << " is even\n Actual: it's " << n;
+// }
+//
+// If Foo() returns 5, you will see the following message:
+//
+// Expected: Foo() is even
+// Actual: it's 5

+// 1. It is possible to make a user-defined type work with

+// Usage Guide. Therefore, you are advised to use the
+// {ASSERT|EXPECT}_TRUE() macro to assert that two objects are
+// equal.
+//
+// 2. The {ASSERT|EXPECT}_??() macros do pointer comparisons on
+// pointers (in particular, C strings). Therefore, if you use it
+// with two C strings, you are testing how their locations in memory
+// are related, not how their content is related. To compare two C
+// strings by content, use {ASSERT|EXPECT}_STR*().
+//
