In particular this results in consistent rounding on all platforms - and removing the ``s[n]printf`` fallback for decimal FP formatting. - -* Compile-time floating point formatting no longer requires the header-only - mode. For example (`godbolt `__): - - .. code:: c++ - - #include - #include - - consteval auto compile_time_dtoa(double value) -> std::array { - auto result = std::array(); - fmt::format_to(result.data(), FMT_COMPILE("{}"), value); - return result; - } - - constexpr auto answer = compile_time_dtoa(0.42); - - works with the default settings. - -* Improved the implementation of - `Dragonbox `_, the algorithm used for - the default floating-point formatting - (`#2713 `_, - `#2750 `_). - Thanks `@jk-jeon (Junekey Jeon) `_. - -* Made ``fmt::to_string`` work with ``__float128``. This uses the internal - FP formatter and works even on system without ``__float128`` support in - ``[s]printf``. - -* Disabled automatic ``std::ostream`` insertion operator (``operator<<``) - discovery when ``fmt/ostream.h`` is included to prevent ODR violations. - You can get the old behavior by defining ``FMT_DEPRECATED_OSTREAM`` but this - will be removed in the next major release. Use ``fmt::streamed`` or - ``fmt::ostream_formatter`` to enable formatting via ``std::ostream`` instead. - -* Added ``fmt::ostream_formatter`` that can be used to write ``formatter`` - specializations that perform formatting via ``std::ostream``. - For example (`godbolt `__): - - .. code:: c++ - - #include - - struct date { - int year, month, day; - - friend std::ostream& operator<<(std::ostream& os, const date& d) { - return os << d.year << '-' << d.month << '-' << d.day; - } - }; - - template <> struct fmt::formatter : ostream_formatter {}; - - std::string s = fmt::format("The date is {}", date{2012, 12, 9}); - // s == "The date is 2012-12-9" - -* Added the ``fmt::streamed`` function that takes an object and formats it - via ``std::ostream``. - For example (`godbolt `__): - - .. code:: c++ - - #include - #include - - int main() { - fmt::print("Current thread id: {}\n", - fmt::streamed(std::this_thread::get_id())); - } - - Note that ``fmt/std.h`` provides a ``formatter`` specialization for - ``std::thread::id`` so you don't need to format it via ``std::ostream``. - -* Deprecated implicit conversions of unscoped enums to integers for consistency - with scoped enums. - -* Added an argument-dependent lookup based ``format_as`` extension API to - simplify formatting of enums. - -* Added experimental ``std::variant`` formatting support - (`#2941 `_). - For example (`godbolt `__): - - .. code:: c++ - - #include - #include - - int main() { - auto v = std::variant(42); - fmt::print("{}\n", v); - } - - prints:: - - variant(42) - - Thanks `@jehelset `_. - -* Added experimental ``std::filesystem::path`` formatting support - (`#2865 `_, - `#2902 `_, - `#2917 `_, - `#2918 `_). - For example (`godbolt `__): - - .. code:: c++ - - #include - #include - - int main() { - fmt::print("There is no place like {}.", std::filesystem::path("/home")); - } - - prints:: - - There is no place like "/home". - - Thanks `@phprus (Vladislav Shchapov) `_. - -* Added a ``std::thread::id`` formatter to ``fmt/std.h``. - For example (`godbolt `__): - - .. code:: c++ - - #include - #include - - int main() { - fmt::print("Current thread id: {}\n", std::this_thread::get_id()); - } - -* Added ``fmt::styled`` that applies a text style to an individual argument - (`#2793 `_). - For example (`godbolt `__): - - .. code:: c++ - - #include - #include - - int main() { - auto now = std::chrono::system_clock::now(); - fmt::print( - "[{}] {}: {}\n", - fmt::styled(now, fmt::emphasis::bold), - fmt::styled("error", fg(fmt::color::red)), - "something went wrong"); - } - - prints - - .. image:: https://user-images.githubusercontent.com/576385/ - 175071215-12809244-dab0-4005-96d8-7cd911c964d5.png - - Thanks `@rbrugo (Riccardo Brugo) `_. - -* Made ``fmt::print`` overload for text styles correctly handle UTF-8 - (`#2681 `_, - `#2701 `_). - Thanks `@AlexGuteniev (Alex Guteniev) `_. - -* Fixed Unicode handling when writing to an ostream. - -* Added support for nested specifiers to range formatting - (`#2673 `_). - For example (`godbolt `__): - - .. code:: c++ - - #include - #include - - int main() { - fmt::print("{::#x}\n", std::vector{10, 20, 30}); - } - - prints ``[0xa, 0x14, 0x1e]``. - - Thanks `@BRevzin (Barry Revzin) `_. - -* Implemented escaping of wide strings in ranges - (`#2904 `_). - Thanks `@phprus (Vladislav Shchapov) `_. - -* Added support for ranges with ``begin`` / ``end`` found via the - argument-dependent lookup - (`#2807 `_). - Thanks `@rbrugo (Riccardo Brugo) `_. - -* Fixed formatting of certain kinds of ranges of ranges - (`#2787 `_). - Thanks `@BRevzin (Barry Revzin) `_. - -* Fixed handling of maps with element types other than ``std::pair`` - (`#2944 `_). - Thanks `@BrukerJWD (Jonathan W) `_. - -* Made tuple formatter enabled only if elements are formattable - (`#2939 `_, - `#2940 `_). - Thanks `@jehelset `_. - -* Made ``fmt::join`` compatible with format string compilation - (`#2719 `_, - `#2720 `_). - Thanks `@phprus (Vladislav Shchapov) `_. - -* Made compile-time checks work with named arguments of custom types and - ``std::ostream`` ``print`` overloads - (`#2816 `_, - `#2817 `_, - `#2819 `_). - Thanks `@timsong-cpp `_. - -* Removed ``make_args_checked`` because it is no longer needed for compile-time - checks (`#2760 `_). - Thanks `@phprus (Vladislav Shchapov) `_. -

Thanks `@vtta `_. - -* Replaced the ``fmt::system_error`` exception with a function of the same - name that constructs ``std::system_error`` - (`#2266 `_). - -* Replaced the ``fmt::windows_error`` exception with a function of the same - name that constructs ``std::system_error`` with the category returned by - ``fmt::system_category()`` - (`#2274 `_, - `#2275 `_). - The latter is similar to ``std::sytem_category`` but correctly handles UTF-8. -

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 `_. - -* 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 '': 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 ------------------- - -* Initial release diff --git a/third_party/fmt-9.1.0/README.rst b/third_party/fmt-9.1.0/README.rst deleted file mode 100644 index cc6d7c41a..000000000 --- a/third_party/fmt-9.1.0/README.rst +++ /dev/null @@ -1,531 +0,0 @@ -.. image:: https://user-images.githubusercontent.com/ - 576385/156254208-f5b743a9-88cf-439d-b0c0-923d53e8d551.png - :width: 25% - :alt: {fmt} - -.. image:: https://github.com/fmtlib/fmt/workflows/linux/badge.svg - :target: https://github.com/fmtlib/fmt/actions?query=workflow%3Alinux - -.. image:: https://github.com/fmtlib/fmt/workflows/macos/badge.svg - :target: https://github.com/fmtlib/fmt/actions?query=workflow%3Amacos - -.. image:: https://github.com/fmtlib/fmt/workflows/windows/badge.svg - :target: https://github.com/fmtlib/fmt/actions?query=workflow%3Awindows - -.. image:: https://oss-fuzz-build-logs.storage.googleapis.com/badges/fmt.svg - :alt: fmt is continuously fuzzed at oss-fuzz - :target: https://bugs.chromium.org/p/oss-fuzz/issues/list?\ - colspec=ID%20Type%20Component%20Status%20Proj%20Reported%20Owner%20\ - Summary&q=proj%3Dfmt&can=1 - -.. image:: https://img.shields.io/badge/stackoverflow-fmt-blue.svg - :alt: Ask questions at StackOverflow with the tag fmt - :target: https://stackoverflow.com/questions/tagged/fmt - -**{fmt}** is an open-source formatting library providing a fast and safe -alternative to C stdio and C++ iostreams. - -If you like this project, please consider donating to one of the funds that -help victims of the war in Ukraine: https://www.stopputin.net/. - -`Documentation `__ - -`Cheat Sheets `__ - -Q&A: ask questions on `StackOverflow with the tag fmt -`_. - -Try {fmt} in `Compiler Explorer `_. - -Features --------- - -* Simple `format API `_ with positional arguments - for localization -* Implementation of `C++20 std::format - `__ -* `Format string syntax `_ similar to Python's - `format `_ -* Fast IEEE 754 floating-point formatter with correct rounding, shortness and - round-trip guarantees -* Safe `printf implementation - `_ including the POSIX - extension for positional arguments -* Extensibility: `support for user-defined types - `_ -* High performance: faster than common standard library implementations of - ``(s)printf``, iostreams, ``to_string`` and ``to_chars``, see `Speed tests`_ - and `Converting a hundred million integers to strings per second - `_ -* Small code size both in terms of source code with the minimum configuration - consisting of just three files, ``core.h``, ``format.h`` and ``format-inl.h``, - and compiled code;

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, ...)) -`_ in GCC. -There is a POSIX extension that adds positional arguments required for -`i18n `_ -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. - -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_to`` with format string compilation on Karma's own benchmark, -see `Converting a hundred million integers to strings per second -`_. - -License -------- - -{fmt} is distributed under the MIT `license -`_. - -Documentation License ---------------------- - -The `Format String Syntax `_ -section in the documentation is

with C++20 compile-time checks. It has minimal include -dependencies for better compile times. This header is only beneficial when -using {fmt} as a library and not in the header-only mode. - -The following functions use :ref:`format string syntax ` -similar to that of Python's `str.format -`_. -They take *fmt* and *args* as arguments. - -*fmt* 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. `~fmt::format_string` is a format string which can be -implicitly constructed from a string literal or a ``constexpr`` string and is -checked at compile time in C++20. To pass a runtime format string wrap it in -`fmt::runtime`. - -*args* is an argument list representing objects to be formatted. - -.. _format: - -.. doxygenfunction:: format(format_string fmt, T&&... args) -> std::string -.. doxygenfunction:: vformat(string_view fmt, format_args args) -> std::string - -.. doxygenfunction:: format_to(OutputIt out, format_string fmt, T&&... args) -> OutputIt -.. doxygenfunction:: format_to_n(OutputIt out, size_t n, format_string fmt, T&&... args) -> format_to_n_result -.. doxygenfunction:: formatted_size(format_string fmt, T&&... args) -> size_t - -.. doxygenstruct:: fmt::format_to_n_result - :members: - -.. _print: - -.. doxygenfunction:: fmt::print(format_string fmt, T&&... args) -.. doxygenfunction:: fmt::vprint(string_view fmt, format_args args) - -.. doxygenfunction:: print(std::FILE *f, format_string fmt, T&&... args) -.. doxygenfunction:: vprint(std::FILE *f, string_view fmt, format_args args) - -Compile-Time Format String Checks ---------------------------------- - -Compile-time checks are enabled by default on compilers that support C++20 -``consteval``. On older compilers you can use the ``FMT_STRING`` macro defined -in ``fmt/format.h`` instead.

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++ - - using namespace fmt::literals; - fmt::print("Hello, {name}!

For example, the code - -.. code:: c++ - - fmt::format("The answer is {:d}", "forty-two"); - -throws the ``format_error`` exception because the argument ``"forty-two"`` is a -string while the format code ``d`` only applies to integers. - -The code - -.. code:: c++ - - format(FMT_STRING("The answer is {:d}"), "forty-two"); - -reports a compile-time error on compilers that support relaxed ``constexpr``. -See `here `_ for details. - -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. 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 desirable. - -Compact Binary Code -------------------- - -The library produces compact per-call compiled code.

API Reference

-

The {fmt} library API consists of the following parts:

- -

All functions and types provided by the library reside in namespace fmt and -macros have prefix FMT_.

-
-

Core API

-

fmt/core.h defines the core API which provides main formatting functions -for char/UTF-8 with C++20 compile-time checks. It has minimal include -dependencies for better compile times. This header is only beneficial when -using {fmt} as a library and not in the header-only mode.

-

The following functions use format string syntax -similar to that of Python’s str.format. -They take fmt and args as arguments.

-

fmt 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. format_string is a format string which can be -implicitly constructed from a string literal or a constexpr string and is -checked at compile time in C++20. To pass a runtime format string wrap it in -fmt::runtime().

-

args is an argument list representing objects to be formatted.

-
-
-template<typename ...T>
auto fmt::format(format_string<T...> fmt, T&&... args) -> std::string
-

Formats args according to specifications in fmt and returns the result -as a string.

-

Example:

-
#include <fmt/core.h>
-std::string message = fmt::format("The answer is {}.", 42);
-
-
-

-

-
- -
-
-auto fmt::vformat(string_view fmt, format_args args) -> std::string
-
- -
-
-template<typename OutputIt, typename ...T>
auto fmt::format_to(OutputIt out, format_string<T...> fmt, T&&... args) -> OutputIt
-

Formats args according to specifications in fmt, writes the result to -the output iterator out and returns the iterator past the end of the output -range. format_to() does not append a terminating null character.

-

Example:

-
auto out = std::vector<char>();
-fmt::format_to(std::back_inserter(out), "{}", 42);
-
-
-

-

-
- -
-
-template<typename OutputIt, typename ...T>
auto fmt::format_to_n(OutputIt out, size_t n, format_string<T...> fmt, T&&... args) -> format_to_n_result<OutputIt>
-

Formats args according to specifications in fmt, writes up to n -characters of the result to the output iterator out and returns the total -(not truncated) output size and the iterator past the end of the output range. -format_to_n() does not append a terminating null character.

-

-

-
- -
-
-template<typename ...T>
auto fmt::formatted_size(format_string<T...> fmt, T&&... args) -> size_t
-

Returns the number of chars in the output of format(fmt, args...).

-
- -
-
-template<typename OutputIt>
struct fmt::format_to_n_result
-
-

Public Members

-
-
-OutputIt out
-

Iterator past the end of the output range.

-
- -
-
-size_t size
-

Total (not truncated) output size.

-
- -
-
- -
-
-template<typename ...T>
void fmt::print(format_string<T...> fmt, T&&... args)
-

Formats args according to specifications in fmt and writes the output -to stdout.

-

Example:

-
fmt::print("Elapsed time: {0:.2f} seconds", 1.23);
-
-
-

-

-
- -
-
-void fmt::vprint(string_view fmt, format_args args)
-
- -
-
-template<typename ...T>
void fmt::print(std::FILE *f, format_string<T...> fmt, T&&... args)
-

Formats args according to specifications in fmt and writes the -output to the file f.

-

Example:

-
fmt::print(stderr, "Don't {}!", "panic");
-
-
-

-

-
- -
-
-void fmt::vprint(std::FILE *f, string_view fmt, format_args args)
-
- -
-

Compile-Time Format String Checks

-

Compile-time checks are enabled by default on compilers that support C++20 -consteval. On older compilers you can use the FMT_STRING macro defined -in fmt/format.h instead. It requires C++14 and is a no-op in C++11.

-
-
-FMT_STRING(s)
-

Constructs a compile-time format string from a string literal s.

-

Example:

-
// A compile-time error because 'd' is an invalid specifier for strings.
-std::string s = fmt::format(FMT_STRING("{:d}"), "foo");
-
-
-

-

-
- -

To force the use of legacy compile-time checks, define the preprocessor variable -FMT_ENFORCE_COMPILE_STRING. When set, functions accepting FMT_STRING -will fail to compile with regular strings. Runtime-checked formatting is still -possible using fmt::vformat, fmt::vprint, etc.

-
-
-template<typename Char, typename ...Args>
class basic_format_string
-

A compile-time format string.

-
- -
-
-template<typename ...Args>
using fmt::format_string = basic_format_string<char, type_identity_t<Args>...>
-
- -
-
-auto fmt::runtime(string_view s) -> basic_runtime<char>
-

Creates a runtime format string.

-

Example:

-
// Check format string at runtime instead of compile-time.
-fmt::print(fmt::runtime("{:d}"), "I am not a number");
-
-
-

-

-
- -
-
-

Named Arguments

-
-
-template<typename Char, typename T>
auto fmt::arg(const Char *name, const T &arg) -> detail::named_arg<Char, T>
-

Returns a named argument to be used in a formatting function. -It should only be used in a call to a formatting function or -dynamic_format_arg_store::push_back.

-

Example:

-
fmt::print("Elapsed time: {s:.2f} seconds", fmt::arg("s", 1.23));
-
-
-

-

-
- -

Named arguments are not supported in compile-time checks at the moment.

-
-
-

Argument Lists

-

You can create your own formatting function with compile-time checks and small -binary footprint, for example (https://godbolt.org/z/oba4Mc):

-
#include <fmt/format.h>
-
-void vlog(const char* file, int line, fmt::string_view format,
-          fmt::format_args args) {
-  fmt::print("{}: {}: ", file, line);
-  fmt::vprint(format, args);
-}
-
-template <typename S, typename... Args>
-void log(const char* file, int line, const S& format, Args&&... args) {
-  vlog(file, line, format, fmt::make_format_args(args...));
-}
-
-#define MY_LOG(format, ...) \
-  log(__FILE__, __LINE__, FMT_STRING(format), __VA_ARGS__)
-
-MY_LOG("invalid squishiness: {}", 42);
-
-
-

Note that vlog is not parameterized on argument types which improves compile -times and reduces binary code size compared to a fully parameterized version.

-
-
-template<typename Context = format_context, typename ...Args>
constexpr auto fmt::make_format_args(Args&&... args) -> format_arg_store<Context, remove_cvref_t<Args>...>
-

Constructs a format_arg_store object that contains references to -arguments and can be implicitly converted to format_args. Context -can be omitted in which case it defaults to context. -See arg() for lifetime considerations.

-

-

-
- -
-
-template<typename Context, typename ...Args>
class format_arg_store
-

An array of references to arguments. It can be implicitly converted into -basic_format_args for passing into type-erased formatting functions -such as vformat().

-

-

-
- -
-
-template<typename Context>
class dynamic_format_arg_store
-
- -
-
-template<typename Context>
class fmt::basic_format_args
-

A view of a collection of formatting arguments. To avoid lifetime issues it -should only be used as a parameter type in type-erased functions such as -vformat:

-
void vlog(string_view format_str, format_args args);  // OK
-format_args args = make_format_args(42);  // Error: dangling reference
-
-
-

-

-
-

-
- -
-
- -
-
-using fmt::string_view = basic_string_view<char>
-
- -
-
-

Locale

-

All formatting is locale-independent by default. Use the 'L' format -specifier to insert the appropriate number separator characters from the -locale:

-
#include <fmt/core.h>
-#include <locale>
-
-std::locale::global(std::locale("en_US.UTF-8"));
-auto s = fmt::format("{:L}", 1000000);  // s == "1,000,000"
-
-
-
-
-
-

Format API

-

fmt/format.h defines the full format API providing additional formatting -functions and locale support.

-
-

Formatting User-Defined Types

-

The {fmt} library provides formatters for many standard C++ types. -See fmt/ranges.h for ranges and tuples including standard -containers such as std::vector, fmt/chrono.h for date -and time formatting and fmt/std.h for path and variant -formatting.

-

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;
-};
-
-template <> struct fmt::formatter<point> {
-  // Presentation format: 'f' - fixed, 'e' - exponential.
-  char presentation = 'f';
-
-  // Parses format specifications of the form ['f' | 'e'].
-  constexpr auto parse(format_parse_context& ctx) -> decltype(ctx.begin()) {
-    // [ctx.begin(), ctx.end()) is a character range that contains a part of
-    // the format string starting from the format specifications to be parsed,
-    // e.g. in
-    //
-    //   fmt::format("{:f} - point of interest", point{1, 2});
-    //
-    // the range will contain "f} - point of interest". The formatter should
-    // parse specifiers until '}' or the end of the range. In this example
-    // the formatter should parse the 'f' specifier and return an iterator
-    // pointing to '}'.
-
-    // Please also note that this character range may be empty, in case of
-    // the "{}" format string, so therefore you should check ctx.begin()
-    // for equality with ctx.end().
-
-    // Parse the presentation format and store it in the formatter:
-    auto it = ctx.begin(), end = ctx.end();
-    if (it != end && (*it == 'f' || *it == 'e')) presentation = *it++;
-
-    // Check if reached the end of the range:
-    if (it != end && *it != '}') throw format_error("invalid format");
-
-    // Return an iterator past the end of the parsed range:
-    return it;
-  }
-
-  // Formats the point p using the parsed format specification (presentation)
-  // stored in this formatter.
-  template <typename FormatContext>
-  auto format(const point& p, FormatContext& ctx) const -> decltype(ctx.out()) {
-    // ctx.out() is an output iterator to write to.
-    return presentation == 'f'
-              ? fmt::format_to(ctx.out(), "({:.1f}, {:.1f})", p.x, p.y)
-              : fmt::format_to(ctx.out(), "({:.1e}, {:.1e})", 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("{:f}", p);
-// s == "(1.0, 2.0)"
-
-
-

You can also reuse existing formatters via inheritance or composition, 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) const {
-    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);
-  }
-};
-
-
-

Since parse is inherited from formatter<string_view> it will recognize -all string format specifications, for example

-
fmt::format("{:>10}", color::blue)
-
-
-

will return "      blue".

-

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) const {
-    return fmt::formatter<std::string>::format(a.name(), ctx);
-  }
-};
-
-int main() {
-  B b;
-  A& a = b;
-  fmt::print("{}", a); // prints "B"
-}
-
-
-

If a type provides both a formatter specialization and an implicit -conversion to a formattable type, the specialization takes precedence over the -conversion.

-

For enums {fmt} also provides the format_as extension API. To format an enum -via this API define format_as that takes this enum and converts it to the -underlying type. format_as should be defined in the same namespace as the -enum.

-

Example (https://godbolt.org/z/r7vvGE1v7):

-
#include <fmt/format.h>
-
-namespace kevin_namespacy {
-enum class film {
-  house_of_cards, american_beauty, se7en = 7
-};
-auto format_as(film f) { return fmt::underlying(f); }
-}
-
-int main() {
-  fmt::print("{}\n", kevin_namespacy::film::se7en); // prints "7"
-}
-
-
-
-
-

Literal-Based API

-

The following user-defined literals are defined in fmt/format.h.

-
-
-template<detail_exported::fixed_string Str>
constexpr auto fmt::operator""_a()
-

User-defined literal equivalent of fmt::arg().

-

Example:

-
using namespace fmt::literals;
-fmt::print("Elapsed time: {s:.2f} seconds", "s"_a=1.23);
-
-
-

-

-
- -
-
-

Utilities

-
-
-template<typename T>
auto fmt::ptr(T p) -> const void*
-

Converts p to const void* for pointer formatting.

-

Example:

-
auto s = fmt::format("{}", fmt::ptr(p));
-
-
-

-

-
- -
-
-template<typename T>
auto fmt::ptr(const std::unique_ptr<T> &p) -> const void*
-
- -
-
-template<typename T>
auto fmt::ptr(const std::shared_ptr<T> &p) -> const void*
-
- -
-
-template<typename Enum>
constexpr auto fmt::underlying(Enum e) noexcept -> underlying_t<Enum>
-

Converts e to the underlying type.

-

Example:

-
enum class color { red, green, blue };
-auto s = fmt::format("{}", fmt::underlying(color::red));
-
-
-

-

-
- -
-
-template<typename T>
auto fmt::to_string(const T &value) -> std::string
-

Converts value to std::string using the default format for type T.

-

Example:

-
#include <fmt/format.h>
-
-std::string answer = fmt::to_string(42);
-
-
-

-

-
- -
-
-template<typename Range>
auto fmt::join(Range &&range, string_view sep) -> join_view<detail::iterator_t<Range>, detail::sentinel_t<Range>>
-

Returns a view that formats range with elements separated by sep.

-

Example:

-
std::vector<int> v = {1, 2, 3};
-fmt::print("{}", fmt::join(v, ", "));
-// Output: "1, 2, 3"
-
-
-

fmt::join applies passed format specifiers to the range elements:

-
fmt::print("{:02}", fmt::join(v, ", "));
-// Output: "01, 02, 03"
-
-
-

-

-
- -
-
-template<typename It, typename Sentinel>
auto fmt::join(It begin, Sentinel end, string_view sep) -> join_view<It, Sentinel>
-

Returns a view that formats the iterator range [begin, end) with elements separated by sep.

-
- -
-
-template<typename T>
auto fmt::group_digits(T value) -> group_digits_view<T>
-

Returns a view that formats an integer value using ‘,’ as a locale-independent -thousands separator.

-

Example:

-
fmt::print("{}", fmt::group_digits(12345));
-// Output: "12,345"
-
-
-

-

-
- -
-
-template<typename T>
class fmt::detail::buffer
-

A contiguous memory buffer with an optional growing ability. It is an internal -class and shouldn’t be used directly, only via basic_memory_buffer.

-

-

-

Subclassed by fmt::basic_memory_buffer< bigit, bigits_capacity >, fmt::basic_memory_buffer< wchar_t >, fmt::basic_memory_buffer< T, SIZE, Allocator >, fmt::detail::iterator_buffer< OutputIt, T, Traits >, fmt::detail::iterator_buffer< T *, T >, fmt::detail::iterator_buffer< T *, T, fixed_buffer_traits >

-
-

-
- -
-
-constexpr auto capacity() const noexcept -> size_t
-

Returns the capacity of this buffer.

-
- -
-
-auto data() noexcept -> T*
-

Returns a pointer to the buffer data.

-
- -
-
-auto data() const noexcept -> const T*
-

Returns a pointer to the buffer data.

-
- -
-
-void clear()
-

-
- -
-
-template<typename U>

-

Appends data to the end of the buffer.

-
- -
-
- -
-
-template<typename T, size_t SIZE = inline_buffer_size, typename Allocator = std::allocator<T>>
class fmt::basic_memory_buffer : public fmt::detail::buffer<T>
-

A dynamically growing memory buffer for trivially copyable/constructible types -with the first SIZE elements stored in the object itself.

-

You can use the memory_buffer type alias for char instead.

-

Example:

-
auto out = fmt::memory_buffer();
-format_to(std::back_inserter(out), "The answer is {}.", 42);
-
-
-

This will append the following output to the out object:

-
The answer is 42.
-
-
-

The output can be converted to an std::string with to_string(out).

-

-

-
-

Public Functions

-
-
-basic_memory_buffer(basic_memory_buffer &&other) noexcept
-

Constructs a fmt::basic_memory_buffer object moving the content -of the other object to it.

-

-

-
- -
-
-auto operator=(basic_memory_buffer &&other) noexcept -> basic_memory_buffer&
-

Moves the content of the other basic_memory_buffer object to this one.

-

-

-
- -
-
-void resize(size_t count)

Resizes the buffer to contain count elements.

-

If T is a POD type new elements may not be initialized.

-
- -
-
-void reserve(size_t new_capacity)
-

Increases the buffer capacity to new_capacity.

-
- -
-
-

Protected Functions

-
-
-void grow(size_t size) override
-

-
- -
-
- -
-
-

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.

-
-
-template<typename ...T>
auto fmt::system_error(int error_code, format_string<T...> fmt, T&&... args) -> std::system_error
-

Constructs std::system_error with a message formatted with -fmt::format(fmt, args...).

-
-

error_code is a system error code as given by errno.

-
-

Example:

-
// This throws std::system_error with the description
-//   cannot open file 'madeup': No such file or directory
-// or similar (system message may vary).
-const char* filename = "madeup";
-std::FILE* file = std::fopen(filename, "r");
-if (!file)
-  throw fmt::system_error(errno, "cannot open file '{}'", filename);
-
-
-

-

-
- -
-
-void fmt::format_system_error(detail::buffer<char> &out, int error_code, const char *message) noexcept
-

Formats an error message for an error returned by an operating system or a -language runtime, for example a file opening error, and writes it to out. -The format is the same as the one used by std::system_error(ec, message) -where ec is std::error_code(error_code, std::generic_category()}). -It is implementation-defined but normally looks like:

-
<message>: <system-message>
-

where <message> is the passed message and <system-message> is the system -message corresponding to the error code. -error_code is a system error code as given by errno.

-

-

-
- -
-
-

Custom Allocators

-

The {fmt} library supports custom dynamic memory allocators. -A custom allocator class can be specified as a template argument to -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) {
-  auto buf = custom_memory_buffer(alloc);
-  fmt::vformat_to(std::back_inserter(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. Formatting functions -normally don’t do any allocations for built-in and string types except for -non-default floating-point formatting that occasionally falls back on -sprintf.

-
-
-
-

Range and Tuple Formatting

-

The library also supports convenient formatting of ranges and tuples:

-
#include <fmt/ranges.h>
-
-std::tuple<char, int, float> t{'a', 1, 2.0f};
-// Prints "('a', 1, 2.0)"
-fmt::print("{}", t);
-
-
-

NOTE: currently, the overload of fmt::join for iterables exists in the main -format.h header, but expect this to change in the future.

-

Using fmt::join, you can separate tuple elements with a custom separator:

-
#include <fmt/ranges.h>
-
-std::tuple<int, char> t = {1, 'a'};
-// Prints "1, a"
-fmt::print("{}", fmt::join(t, ", "));
-
-
-
-
-

Date and Time Formatting

-

fmt/chrono.h provides formatters for

- -

The format syntax is described in Chrono Format Specifications.

-

Example:

-
#include <fmt/chrono.h>
-
-int main() {
-  std::time_t t = std::time(nullptr);
-
-  // Prints "The date is 2020-11-07." (with the current date):
-  fmt::print("The date is {:%Y-%m-%d}.", fmt::localtime(t));
-
-  using namespace std::literals::chrono_literals;
-
-  // Prints "Default format: 42s 100ms":
-  fmt::print("Default format: {} {}\n", 42s, 100ms);
-
-  // Prints "strftime-like format: 03:15:30":
-  fmt::print("strftime-like format: {:%H:%M:%S}\n", 3h + 15min + 30s);
-}
-
-
-
-
-std::tm fmt::localtime(std::time_t time)
-

Converts given time since epoch as std::time_t value into calendar time, expressed in local time.

-

Unlike std::localtime, this function is thread-safe on most platforms.

-
- -
-
-std::tm fmt::gmtime(std::time_t time)
-

Converts given time since epoch as std::time_t value into calendar time, expressed in Coordinated Universal Time (UTC).

-

Unlike std::gmtime, this function is thread-safe on most platforms.

-
- -
-
-

Standard Library Types Formatting

-

fmt/std.h provides formatters for:

- -
-

Formatting Variants

-

A std::variant is only formattable if every variant alternative is formattable, and requires the -__cpp_lib_variant library feature.

-

Example:

-
#include <fmt/std.h>
-
-std::variant<char, float> v0{'x'};
-// Prints "variant('x')"
-fmt::print("{}", v0);
-
-std::variant<std::monostate, char> v1;
-// Prints "variant(monostate)"
-
-
-
-
-
-

Format String Compilation

-

fmt/compile.h provides format string compilation enabled via the -FMT_COMPILE macro or the _cf user-defined literal. Format strings -marked with FMT_COMPILE or _cf are parsed, checked and converted into -efficient formatting code at compile-time. This supports arguments of built-in -and string types as well as user-defined types with constexpr parse -functions in their formatter specializations. Format string compilation can -generate more binary code compared to the default API and is only recommended in -places where formatting is a performance bottleneck.

-
-
-FMT_COMPILE(s)
-

Converts a string literal s into a format string that will be parsed at -compile time and converted into efficient formatting code. Requires C++17 -constexpr if compiler support.

-

Example:

-
// Converts 42 into std::string using the most efficient method and no
-// runtime format string processing.
-std::string s = fmt::format(FMT_COMPILE("{}"), 42);
-
-
-

-

-
- -
-
-template<detail_exported::fixed_string Str>
constexpr auto fmt::operator""_cf()
-
- -
-
-

Terminal Color and Text Style

-

fmt/color.h provides support for terminal color and text style output.

-
-
-template<typename S, typename ...Args>
void fmt::print(const text_style &ts, const S &format_str, const Args&... args)
-

Formats a string and prints it to stdout using ANSI escape sequences to -specify text formatting.

-

Example:

-
fmt::print(fmt::emphasis::bold | fg(fmt::color::red),
-           "Elapsed time: {0:.2f} seconds", 1.23);
-
-
-

-

-
- -
-
-text_style fmt::fg(detail::color_type foreground) noexcept
-

Creates a text style from the foreground (text) color.

-
- -
-
-text_style fmt::bg(detail::color_type background) noexcept
-

Creates a text style from the background color.

-
- -
-
-template<typename T>
auto fmt::styled(const T &value, text_style ts) -> detail::styled_arg<remove_cvref_t<T>>
-

Returns an argument that will be formatted using ANSI escape sequences, -to be used in a formatting function.

-

Example:

-
fmt::print("Elapsed time: {0:.2f} seconds",
-           fmt::styled(1.23, fmt::fg(fmt::color::green) |
-                             fmt::bg(fmt::color::blue)));
-
-
-

-

-
- -
-
-

System APIs

-
-
-class fmt::ostream : private fmt::detail::buffer<char>
-

A fast output stream which is not thread-safe.

-
-

Public Functions

-
-
-template<typename ...T>
void print(format_string<T...> fmt, T&&... args)
-

Formats args according to specifications in fmt and writes the output to the file.

-
- -
-
-

Friends

-
-
-template<typename ...T>
ostream output_file(cstring_view path, T... params)
-

Opens a file for writing. Supported parameters passed in params:

-
    -

  • <integer>: Flags passed to open -(file::WRONLY | file::CREATE | file::TRUNC by default)

    • -

  • buffer_size=<integer>: Output buffer size

    • -
-

Example:

-
auto out = fmt::output_file("guide.txt");
-out.print("Don't {}", "Panic");
-
-
-

-

-
- -
-
- -
-
-

std::ostream Support

-

fmt/ostream.h provides std::ostream support including formatting of -user-defined types that have an overloaded insertion operator (operator<<). -In order to make a type formattable via std::ostream you should provide a -formatter specialization inherited from ostream_formatter:

-
#include <fmt/ostream.h>
-
-struct date {
-  int year, month, day;
-
-  friend std::ostream& operator<<(std::ostream& os, const date& d) {
-    return os << d.year << '-' << d.month << '-' << d.day;
-  }
-};
-
-template <> struct fmt::formatter<date> : ostream_formatter {};
-
-std::string s = fmt::format("The date is {}", date{2012, 12, 9});
-// s == "The date is 2012-12-9"
-
-
-
-
-template<typename T>
auto fmt::streamed(const T &value) -> detail::streamed_view<T>
-

Returns a view that formats value via an ostream operator<<.

-

Example:

-
fmt::print("Current thread id: {}\n",
-           fmt::streamed(std::this_thread::get_id()));
-
-
-

-

-
- -
-
-template<typename ...T>
void fmt::print(std::ostream &os, format_string<T...> fmt, T&&... args)
-

Prints formatted data to the stream os.

-

Example:

-
fmt::print(cerr, "Don't {}!", "panic");
-
-
-

-

-
- -
-
-

printf Formatting

-

The header fmt/printf.h provides printf-like formatting functionality. -The following functions use printf format string syntax 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.

-
-
-template<typename S, typename ...T>
auto fmt::printf(const S &fmt, const T&... args) -> int
-

Prints formatted data to stdout.

-

Example:

-
fmt::printf("Elapsed time: %.2f seconds", 1.23);
-
-
-

-

-
- -
-
-template<typename S, typename ...T, typename Char = char_t<S>>
auto fmt::fprintf(std::FILE *f, const S &fmt, const T&... args) -> int
-

Prints formatted data to the file f.

-

Example:

-
fmt::fprintf(stderr, "Don't %s!", "panic");
-
-
-

-

-
- -
-
-template<typename S, typename ...T, typename Char = enable_if_t<detail::is_string<S>::value, char_t<S>>>
auto fmt::sprintf(const S &fmt, const T&... args) -> std::basic_string<Char>
-

Formats arguments and returns the result as a string.

-

Example:

-
std::string message = fmt::sprintf("The answer is %d", 42);
-
-
-

-

-
- -
-
-

wchar_t Support

-

The optional header fmt/xchar.h provides support for wchar_t and exotic -character types.

-
-
-template<typename T>
struct is_char : public std::false_type
-

Specifies if T is a character type.

-

Can be specialized by users.

-
- -
-
-using fmt::wstring_view = basic_string_view<wchar_t>
-
- -
-
-using fmt::wformat_context = buffer_context<wchar_t>
-
- -
-
-template<typename T>
auto fmt::to_wstring(const T &value) -> std::wstring
-

Converts value to std::wstring using the default format for type T.

-
- -
-
-

Compatibility with C++20 std::format

-

{fmt} implements nearly all of the C++20 formatting library with the following -differences:

-
    -

  • Names are defined in the fmt namespace instead of std to avoid -collisions with standard library implementations.

    • -

  • Width calculation doesn’t use grapheme clusterization. The latter has been -implemented in a separate branch but hasn’t been integrated yet.

    • -

  • Most C++20 chrono types are not supported yet.

    • -

{fmt} is an open-source formatting library providing a fast and safe -alternative to C stdio and C++ iostreams.

-
-
What users say:
-
- 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. -
-
-

Format API

-

The format API is similar in spirit to the C printf family of function but -is safer, simpler and several times faster -than common standard library implementations. -The format string syntax is similar to the one used by -str.format in -Python:

-
std::string s = 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:

-
auto out = fmt::memory_buffer();
-fmt::format_to(std::back_inserter(out),
-          "For a moment, {} happened.", "nothing");
-auto data = out.data(); // pointer to the formatted data
-auto size = out.size(); // size of the formatted data
-
-
-

The fmt::print function performs formatting and writes the result to a stream:

-
fmt::print(stderr, "System error code = {}\n", errno);
-
-
-

If you omit the file argument the function will print to stdout:

-
fmt::print("Don't {}\n", "panic");
-
-
-

The format API also supports positional arguments useful for localization:

-
fmt::print("I'd rather be {1} than {0}.", "right", "happy");
-
-
-

You can pass named arguments with fmt::arg:

-
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:

-
using namespace fmt::literals;
-fmt::print("Hello, {name}! The answer is {number}. Goodbye, {name}.",
-           "name"_a="World", "number"_a=42);
-
-
-
-
-

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

-
fmt::format("The answer is {:d}", "forty-two");
-
-
-

throws the format_error exception because the argument "forty-two" is a -string while the format code d only applies to integers.

-

The code

-
format(FMT_STRING("The answer is {:d}"), "forty-two");
-
-
-

reports a compile-time error on compilers that support relaxed constexpr. -See here for details.

-

The following code

-
fmt::format("Cyrillic letter {}", L'\x42e');
-
-
-

produces a compile-time error because wide character L'\x42e' cannot be -formatted into a narrow string. 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 desirable.

-
-
-

Compact Binary Code

-

The library produces compact per-call compiled code. For example -(godbolt),

-
#include <fmt/core.h>
-
-int main() {
-  fmt::print("The answer is {}.", 42);
-}
-
-
-

compiles to just

-
main: # @main
-  sub rsp, 24
-  mov qword ptr [rsp], 42
-  mov rcx, rsp
-  mov edi, offset .L.str
-  mov esi, 17
-  mov edx, 1
-  call fmt::v7::vprint(fmt::v7::basic_string_view<char>, fmt::v7::format_args)
-  xor eax, eax
-  add rsp, 24
-  ret
-.L.str:
-  .asciz "The answer is {}."
-
-
-
-
-

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 in GCC 4.8, Clang 3.4, MSVC 19.0 (2015) and more recent -compiler version. For older compilers use {fmt} version 4.x which is maintained and -only requires C++98.

-

The output of all formatting functions is consistent across platforms. -For example,

-
fmt::print("{}", std::numeric_limits<double>::infinity());
-
-
-

always prints inf while the output of printf is platform-dependent.

-
-
-

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 MIT license allows -using the library both in open-source and commercial projects.

Format String Syntax

-

Formatting functions such as fmt::format() and -fmt::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:

-
-replacement_field ::=  "{" [arg_id] [":" (format_spec | chrono_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 Format Specification Mini-Language 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 Format Examples section for some examples.

-
-

Format Specification Mini-Language

-

“Format specifications” are used within replacement fields contained within a -format string to define how individual values are presented (see -Format String 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:

-
-format_spec ::=  [[fill]align][sign]["#"]["0"][width]["." precision]["L"][type]
-fill        ::=  <a character other than '{' or '}'>
-align       ::=  "<" | ">" | "^"
-sign        ::=  "+" | "-" | " "
-width       ::=  integer | "{" [arg_id] "}"
-precision   ::=  integer | "{" [arg_id] "}"
-type        ::=  "a" | "A" | "b" | "B" | "c" | "d" | "e" | "E" | "f" | "F" | "g" | "G" |
-                 "o" | "p" | "s" | "x" | "X"
-
-

The fill character can be any Unicode code point other than '{' or -'}'. 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 -nonnegative 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 -nonnegative 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.

-

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. Note that a C string must be -null-terminated even if precision is specified.

-

The 'L' option uses the current locale setting to insert the appropriate -number separator characters. This option is only valid for numeric types.

-

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.

'c'

Character format. Outputs the number as a character.

'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.

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.

none

Similar to 'g', except that the default precision is -as high as needed to represent the particular value.

-

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'.

Chrono Format Specifications

-

Format specifications for chrono types and std::tm have the following -syntax:

-
-chrono_format_spec ::=  [[fill]align][width]["." precision][chrono_specs]
-chrono_specs       ::=  [chrono_specs] conversion_spec | chrono_specs literal_char
-conversion_spec    ::=  "%" [modifier] chrono_type
-literal_char       ::=  <a character other than '{', '}' or '%'>
-modifier           ::=  "E" | "O"
-chrono_type        ::=  "a" | "A" | "b" | "B" | "c" | "C" | "d" | "D" | "e" | "F" |
-                        "g" | "G" | "h" | "H" | "I" | "j" | "m" | "M" | "n" | "p" |
-                        "q" | "Q" | "r" | "R" | "S" | "t" | "T" | "u" | "U" | "V" |
-                        "w" | "W" | "x" | "X" | "y" | "Y" | "z" | "Z" | "%"
-
-

Literal chars are copied unchanged to the output. Precision is valid only for -std::chrono::duration types with a floating-point representation type.

-

The available presentation types (chrono_type) for chrono durations and time -points are:

- ---- - - - - - - - - - - - - - - - - -

Type

Meaning

'H'

The hour (24-hour clock) as a decimal number. If the result is a -single digit, it is prefixed with 0. The modified command %OH -produces the locale’s alternative representation.

'M'

The minute as a decimal number. If the result is a single digit, -it is prefixed with 0. The modified command %OM produces the -locale’s alternative representation.

'S'

Seconds as a decimal number. If the number of seconds is less than -10, the result is prefixed with 0. If the precision of the input -cannot be exactly represented with seconds, then the format is a -decimal floating-point number with a fixed format and a precision -matching that of the precision of the input (or to a microseconds -precision if the conversion to floating-point decimal seconds -cannot be made within 18 fractional digits). The character for the -decimal point is localized according to the locale. The modified -command %OS produces the locale’s alternative representation.

-

Specifiers that have a calendaric component such as 'd' (the day of month) -are valid only for std::tm and not durations or time points.

-
-
-

Range Format Specifications

-

Format specifications for range types have the following syntax:

-
-range_format_spec ::=  [":" [underlying_spec]]
-
-

The underlying_spec is parsed based on the formatter of the range’s -reference type.

-

By default, a range of characters or strings is printed escaped and quoted. But -if any underlying_spec is provided (even if it is empty), then the characters -or strings are printed according to the provided specification.

-

Examples:

-
fmt::format("{}", std::vector{10, 20, 30});
-// Result: [10, 20, 30]
-fmt::format("{::#x}", std::vector{10, 20, 30});
-// Result: [0xa, 0x14, 0x13]
-fmt::format("{}", vector{'h', 'e', 'l', 'l', 'o'});
-// Result: ['h', 'e', 'l', 'l', 'o']
-fmt::format("{::}", vector{'h', 'e', 'l', 'l', 'o'});
-// Result: [h, e, l, l, o]
-fmt::format("{::d}", vector{'h', 'e', 'l', 'l', 'o'});
-// Result: [104, 101, 108, 108, 111]
-
-
-
-
-

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:

-
fmt::format("{0}, {1}, {2}", 'a', 'b', 'c');
-// Result: "a, b, c"
-fmt::format("{}, {}, {}", 'a', 'b', 'c');
-// Result: "a, b, c"
-fmt::format("{2}, {1}, {0}", 'a', 'b', 'c');
-// Result: "c, b, a"
-fmt::format("{0}{1}{0}", "abra", "cad");  // arguments' indices can be repeated
-// Result: "abracadabra"
-
-
-

Aligning the text and specifying a width:

-
fmt::format("{:<30}", "left aligned");
-// Result: "left aligned                  "
-fmt::format("{:>30}", "right aligned");
-// Result: "                 right aligned"
-fmt::format("{:^30}", "centered");
-// Result: "           centered           "
-fmt::format("{:*^30}", "centered");  // use '*' as a fill char
-// Result: "***********centered***********"
-
-
-

Dynamic width:

-
fmt::format("{:<{}}", "left aligned", 30);
-// Result: "left aligned                  "
-
-
-

Dynamic precision:

-
fmt::format("{:.{}f}", 3.14, 1);
-// Result: "3.1"
-
-
-

Replacing %+f, %-f, and % f and specifying a sign:

-
fmt::format("{:+f}; {:+f}", 3.14, -3.14);  // show it always
-// Result: "+3.140000; -3.140000"
-fmt::format("{: f}; {: f}", 3.14, -3.14);  // show a space for positive numbers
-// Result: " 3.140000; -3.140000"
-fmt::format("{:-f}; {:-f}", 3.14, -3.14);  // show only the minus -- same as '{:f}; {:f}'
-// Result: "3.140000; -3.140000"
-
-
-

Replacing %x and %o and converting the value to different bases:

-
fmt::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:
-fmt::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:

-
fmt::format("{:#04x}", 0);
-// Result: "0x00"
-
-
-

Box drawing using Unicode fill:

-
fmt::print(
-  "┌{0:─^{2}}┐\n"
-  "│{1: ^{2}}│\n"
-  "└{0:─^{2}}┘\n", "", "Hello, world!", 20);
-
-
-

prints:

-
┌────────────────────┐
-│   Hello, world!    │
-└────────────────────┘
-
-
-

Using type-specific formatting:

-
#include <fmt/chrono.h>
-
-auto t = tm();
-t.tm_year = 2010 - 1900;
-t.tm_mon = 7;
-t.tm_mday = 4;
-t.tm_hour = 12;
-t.tm_min = 15;
-t.tm_sec = 58;
-fmt::print("{:%Y-%m-%d %H:%M:%S}", t);
-// Prints: 2010-08-04 12:15:58
-
-
-

Using the comma as a thousands separator:

-
#include <fmt/format.h>
-
-auto s = fmt::format(std::locale("en_US.UTF-8"), "{:L}", 1234567890);
-// s == "1,234,567,890"

Usage

-

To use the {fmt} library, add fmt/core.h, fmt/format.h, -fmt/format-inl.h, src/format.cc and optionally other headers -from a release archive or -the Git repository to your project. -Alternatively, you can build the library with CMake.

-
-

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 https://www.cmake.org/download/.

-

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 <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 make.

-

Once the library has been built you can invoke 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 FMT.sln -file and several .vcproj files will be created. You can then build them -using Visual Studio or msbuild.

-

On Mac OS X with Xcode installed, an .xcodeproj file will be generated.

-

To build a shared library set the BUILD_SHARED_LIBS CMake variable to -TRUE:

-
cmake -DBUILD_SHARED_LIBS=TRUE ...
-
-
-

To build a static library with position independent code (required if the main -consumer of the fmt library is a shared library i.e. a Python extension) set the -CMAKE_POSITION_INDEPENDENT_CODE CMake variable to TRUE:

-
cmake -DCMAKE_POSITION_INDEPENDENT_CODE=TRUE ...
-
-
-
-
-

Installing the Library

-

After building the library you can install it on a Unix-like system by running -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)
-
-
-
-
-

Usage with build2

-

You can use build2, a dependency manager and a -build-system combined, to use fmt.

-

Currently this package is available in these package repositories:

- -

Usage:

-
    -

  • build2 package name: fmt

    • -

  • Library target name : lib{fmt}

    • -
-

For example, to make your build2 project depend on fmt:

-
    -

  • Add one of the repositories to your configurations, or in your -repositories.manifest, if not already there:

    -
    :
-role: prerequisite
-location: https://pkg.cppget.org/1/stable
-
    -
    -
    • -

  • Add this package as a dependency to your ./manifest file -(example for v7.0.x):

    -
    depends: fmt ~7.0.0
-
    -
    -
    • -

  • Import the target and use it as a prerequisite to your own target -using fmt in the appropriate buildfile:

    -
    import fmt = fmt%lib{fmt}
-lib{mylib} : cxx{**} ... $fmt
-
    -
    -
    • -
-

Then build your project as usual with b or bdep update.

-

For build2 newcomers or to get more details and use cases, you can read the -build2 -toolchain introduction.

-
-
-

Building the Documentation

-

To build the documentation you need the following software installed on your -system:

-
    -

  • Python with pip and virtualenv

    • -

  • Doxygen

    • -

  • Less 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.

-
-
-

Conda

-

fmt can be installed on Linux, macOS and Windows with -Conda, using its -conda-forge -package, as follows:

-
conda install -c conda-forge fmt
-
-
-
-
-

Vcpkg

-

You can download and install fmt using the vcpkg dependency manager:

-
git clone https://github.com/Microsoft/vcpkg.git
-cd vcpkg
-./bootstrap-vcpkg.sh
-./vcpkg integrate install
-./vcpkg install fmt
-
-
-

The fmt port in vcpkg is kept up to date by Microsoft team members and community -contributors. If the version is out of date, please create an issue or pull -request on the vcpkg repository.

-
-
-

LHelper

-

You can download and install fmt using -lhelper dependency manager:

-
lhelper activate <some-environment>
-lhelper install fmt
-
-
-

All the recipes for lhelper are kept in the -lhelper’s recipe repository.

-
-
-

Android NDK

-

fmt provides Android.mk file that can be used to build the library -with Android NDK. -For an example of using fmt with Android NDK, see the -android-ndk-example -repository.

-
-
-

Homebrew

-

fmt can be installed on OS X using Homebrew:

-
brew install fmt

You can get the old behavior by defining + `FMT_DEPRECATED_OSTREAM` but this will be removed in the next major + release. Use `fmt::streamed` or `fmt::ostream_formatter` to enable + formatting via `std::ostream` instead. + +- Added `fmt::ostream_formatter` that can be used to write `formatter` + specializations that perform formatting via `std::ostream`.

It can be used instead of the `FMT_COMPILE` macro + (https://github.com/fmtlib/fmt/pull/2043, + https://github.com/fmtlib/fmt/pull/2242): + + ```c++ + #include + + using namespace fmt::literals; + auto s = fmt::format(FMT_COMPILE("{}"), 42); // 🙁 not modern + auto s = fmt::format("{}"_cf, 42); // 🙂 modern as hell + ``` + + It requires compiler support for class types in non-type template + parameters (a C++20 feature) which is available in GCC 9.3+. + Thanks @alexezeder. + +- Format string compilation now requires `format` functions of + `formatter` specializations for user-defined types to be `const`: + + ```c++ + template <> struct fmt::formatter: formatter { + template + auto format(my_type obj, FormatContext& ctx) const { // Note const here. + // ... + } + }; + ``` + +- Added UDL-based named argument support to format string compilation + (https://github.com/fmtlib/fmt/pull/2243, + https://github.com/fmtlib/fmt/pull/2281). For example: + + ```c++ + #include + + using namespace fmt::literals; + auto s = fmt::format(FMT_COMPILE("{answer}"), "answer"_a = 42); + ``` + + Here the argument named \"answer\" is resolved at compile time with + no runtime overhead. Thanks @alexezeder. + +- Added format string compilation support to `fmt::print` + (https://github.com/fmtlib/fmt/issues/2280, + https://github.com/fmtlib/fmt/pull/2304). Thanks @alexezeder. + +- Added initial support for compiling {fmt} as a C++20 module + (https://github.com/fmtlib/fmt/pull/2235, + https://github.com/fmtlib/fmt/pull/2240, + https://github.com/fmtlib/fmt/pull/2260, + https://github.com/fmtlib/fmt/pull/2282, + https://github.com/fmtlib/fmt/pull/2283, + https://github.com/fmtlib/fmt/pull/2288, + https://github.com/fmtlib/fmt/pull/2298, + https://github.com/fmtlib/fmt/pull/2306, + https://github.com/fmtlib/fmt/pull/2307, + https://github.com/fmtlib/fmt/pull/2309, + https://github.com/fmtlib/fmt/pull/2318, + https://github.com/fmtlib/fmt/pull/2324, + https://github.com/fmtlib/fmt/pull/2332, + https://github.com/fmtlib/fmt/pull/2340). Thanks @DanielaE. + +- Made symbols private by default reducing shared library size + (https://github.com/fmtlib/fmt/pull/2301). For example + there was a \~15% reported reduction on one platform. Thanks @sergiud. + +- Optimized includes making the result of preprocessing `fmt/format.h` + \~20% smaller with libstdc++/C++20 and slightly improving build + times (https://github.com/fmtlib/fmt/issues/1998). + +- Added support of ranges with non-const `begin` / `end` + (https://github.com/fmtlib/fmt/pull/1953). Thanks @kitegi. + +- Added support of `std::byte` and other formattable types to + `fmt::join` (https://github.com/fmtlib/fmt/issues/1981, + https://github.com/fmtlib/fmt/issues/2040, + https://github.com/fmtlib/fmt/pull/2050, + https://github.com/fmtlib/fmt/issues/2262). For example: + + ```c++ + #include + #include + #include + + int main() { + auto bytes = std::vector{std::byte(4), std::byte(2)}; + fmt::print("{}", fmt::join(bytes, "")); + } + ``` + + prints \"42\". + + Thanks @kamibo. + +- Implemented the default format for `std::chrono::system_clock` + (https://github.com/fmtlib/fmt/issues/2319, + https://github.com/fmtlib/fmt/pull/2345). For example: + + ```c++ + #include + + int main() { + fmt::print("{}", std::chrono::system_clock::now()); + } + ``` + + prints \"2021-06-18 15:22:00\" (the output depends on the current + date and time). Thanks @sunmy2019. + +- Made more chrono specifiers locale independent by default. Use the + `'L'` specifier to get localized formatting. For example: + + ```c++ + #include + + int main() { + std::locale::global(std::locale("ru_RU.UTF-8")); + auto monday = std::chrono::weekday(1); + fmt::print("{}\n", monday); // prints "Mon" + fmt::print("{:L}\n", monday); // prints "пн" + } + ``` + +- Improved locale handling in chrono formatting + (https://github.com/fmtlib/fmt/issues/2337, + https://github.com/fmtlib/fmt/pull/2349, + https://github.com/fmtlib/fmt/pull/2350). Thanks @phprus. + +- Deprecated `fmt/locale.h` moving the formatting functions that take + a locale to `fmt/format.h` (`char`) and `fmt/xchar` (other + overloads). This doesn\'t introduce a dependency on `` so + there is virtually no compile time effect. + +- Deprecated an undocumented `format_to` overload that takes + `basic_memory_buffer`. + +- Made parameter order in `vformat_to` consistent with `format_to` + (https://github.com/fmtlib/fmt/issues/2327). + +- Added support for time points with arbitrary durations + (https://github.com/fmtlib/fmt/issues/2208). For example: + + ```c++ + #include + + int main() { + using tp = std::chrono::time_point< + std::chrono::system_clock, std::chrono::seconds>; + fmt::print("{:%S}", tp(std::chrono::seconds(42))); + } + ``` + + prints \"42\". + +- Formatting floating-point numbers no longer produces trailing zeros + by default for consistency with `std::format`. For example: + + ```c++ + #include + + int main() { + fmt::print("{0:.3}", 1.1); + } + ``` + + prints \"1.1\". Use the `'#'` specifier to keep trailing zeros. + +- Dropped a limit on the number of elements in a range and replaced + `{}` with `[]` as range delimiters for consistency with Python\'s + `str.format`. + +- The `'L'` specifier for locale-specific numeric formatting can now + be combined with presentation specifiers as in `std::format`. For + example: + + ```c++ + #include + #include + + int main() { + std::locale::global(std::locale("fr_FR.UTF-8")); + fmt::print("{0:.2Lf}", 0.42); + } + ``` + + prints \"0,42\". The deprecated `'n'` specifier has been removed. + +- Made the `0` specifier ignored for infinity and NaN + (https://github.com/fmtlib/fmt/issues/2305, + https://github.com/fmtlib/fmt/pull/2310). Thanks @Liedtke. + +- Made the hexfloat formatting use the right alignment by default + (https://github.com/fmtlib/fmt/issues/2308, + https://github.com/fmtlib/fmt/pull/2317). Thanks @Liedtke. + +- Removed the deprecated numeric alignment (`'='`). Use the `'0'` + specifier instead. + +- Removed the deprecated `fmt/posix.h` header that has been replaced + with `fmt/os.h`. + +- Removed the deprecated `format_to_n_context`, `format_to_n_args` and + `make_format_to_n_args`. They have been replaced with + `format_context`, `` format_args` and ``make_format_args\`\` + respectively. + +- Moved `wchar_t`-specific functions and types to `fmt/xchar.h`. You + can define `FMT_DEPRECATED_INCLUDE_XCHAR` to automatically include + `fmt/xchar.h` from `fmt/format.h` but this will be disabled in the + next major release. + +- Fixed handling of the `'+'` specifier in localized formatting + (https://github.com/fmtlib/fmt/issues/2133). + +- Added support for the `'s'` format specifier that gives textual + representation of `bool` + (https://github.com/fmtlib/fmt/issues/2094, + https://github.com/fmtlib/fmt/pull/2109). For example: + + ```c++ + #include + + int main() { + fmt::print("{:s}", true); + } + ``` + + prints \"true\". Thanks @powercoderlol. + +- Made `fmt::ptr` work with function pointers + (https://github.com/fmtlib/fmt/pull/2131). For example: + + ```c++ + #include + + int main() { + fmt::print("My main: {}\n", fmt::ptr(main)); + } + ``` + + Thanks @mikecrowe. + +- The undocumented support for specializing `formatter` for pointer + types has been removed. + +- Fixed `fmt::formatted_size` with format string compilation + (https://github.com/fmtlib/fmt/pull/2141, + https://github.com/fmtlib/fmt/pull/2161). Thanks @alexezeder. + +- Fixed handling of empty format strings during format string + compilation (https://github.com/fmtlib/fmt/issues/2042): + + ```c++ + auto s = fmt::format(FMT_COMPILE("")); + ``` + + Thanks @alexezeder. + +- Fixed handling of enums in `fmt::to_string` + (https://github.com/fmtlib/fmt/issues/2036). + +- Improved width computation + (https://github.com/fmtlib/fmt/issues/2033, + https://github.com/fmtlib/fmt/issues/2091). For example: + + ```c++ + #include + + int main() { + fmt::print("{:-<10}{}\n", "你好", "世界"); + fmt::print("{:-<10}{}\n", "hello", "world"); + } + ``` + + prints + + ![](https://user-images.githubusercontent.com/576385/119840373-cea3ca80-beb9-11eb-91e0-54266c48e181.png) + + on a modern terminal. + +- The experimental fast output stream (`fmt::ostream`) is now + truncated by default for consistency with `fopen` + (https://github.com/fmtlib/fmt/issues/2018). For example: + + ```c++ + #include + + int main() { + fmt::ostream out1 = fmt::output_file("guide"); + out1.print("Zaphod"); + out1.close(); + fmt::ostream out2 = fmt::output_file("guide"); + out2.print("Ford"); + } + ``` + + writes \"Ford\" to the file \"guide\". To preserve the old file + content if any pass `fmt::file::WRONLY | fmt::file::CREATE` flags to + `fmt::output_file`. + +- Fixed moving of `fmt::ostream` that holds buffered data + (https://github.com/fmtlib/fmt/issues/2197, + https://github.com/fmtlib/fmt/pull/2198). Thanks @vtta. + +- Replaced the `fmt::system_error` exception with a function of the + same name that constructs `std::system_error` + (https://github.com/fmtlib/fmt/issues/2266). + +- Replaced the `fmt::windows_error` exception with a function of the + same name that constructs `std::system_error` with the category + returned by `fmt::system_category()` + (https://github.com/fmtlib/fmt/issues/2274, + https://github.com/fmtlib/fmt/pull/2275). The latter is + similar to `std::sytem_category` but correctly handles UTF-8. + Thanks @phprus. + +- Replaced `fmt::error_code` with `std::error_code` and made it + formattable (https://github.com/fmtlib/fmt/issues/2269, + https://github.com/fmtlib/fmt/pull/2270, + https://github.com/fmtlib/fmt/pull/2273). Thanks @phprus. + +- Added speech synthesis support + (https://github.com/fmtlib/fmt/pull/2206). + +- Made `format_to` work with a memory buffer that has a custom + allocator (https://github.com/fmtlib/fmt/pull/2300). + Thanks @voxmea. + +- Added `Allocator::max_size` support to `basic_memory_buffer`. + (https://github.com/fmtlib/fmt/pull/1960). Thanks @phprus. + +- Added wide string support to `fmt::join` + (https://github.com/fmtlib/fmt/pull/2236).

You can use this macro for + defining your own portable variadic functions: + + ```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: + + ```c++ + std::string s = format("The answer is {}.", 42); + ``` + + Previously it required 2 function calls: + + ```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`: + + ```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.

Use the `str` function to convert it to + `std::string`: + + ```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 + + ```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 \'\\': 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.

+ +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, +\...))](https://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: + +``` c++ +std::cout << std::setprecision(2) << std::fixed << 1.23456 << "\n"; +``` + +which is a lot of typing compared to printf: + +``` 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 that 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](#benchmarks)). + +## FastFormat + +This is an interesting library that 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. + +## Boost Spirit.Karma + +This is not 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_to` with format string compilation +on Karma\'s own benchmark, see [Converting a hundred million integers to +strings per +second](http://www.zverovich.net/2020/06/13/fast-int-to-string-revisited.html). + +# License + +{fmt} is distributed under the MIT +[license](https://github.com/fmtlib/fmt/blob/master/LICENSE). + +# Documentation License + +The [Format String Syntax](https://fmt.dev/latest/syntax.html) section +in the documentation is based on the one from Python [string module +documentation](https://docs.python.org/3/library/string.html#module-string). +For this reason, the documentation is distributed under the Python +Software Foundation license available in +[doc/python-license.txt](https://raw.github.com/fmtlib/fmt/master/doc/python-license.txt). +It only applies if you distribute the documentation of {fmt}. + +# Maintainers + +The {fmt} library is maintained by Victor Zverovich +([vitaut](https://github.com/vitaut)) with contributions from many other +people.

The ``format_as`` function should take an +object of your type and return an object of a formattable type. It should be +defined in the same namespace as your type. + +Example (https://godbolt.org/z/nvME4arz8):: + + #include + + namespace kevin_namespacy { + enum class film { + house_of_cards, american_beauty, se7en = 7 + }; + auto format_as(film f) { return fmt::underlying(f); } + } + + int main() { + fmt::print("{}\n", kevin_namespacy::film::se7en); // prints "7" + } + +Using specialization is more complex but gives you full control over parsing and +formatting. To use this method specialize the ``formatter`` struct template for +your type and implement ``parse`` and ``format`` methods. + +The recommended way of defining a formatter is by reusing an existing one via +inheritance or composition. This way you can support standard format specifiers +without implementing them yourself. For example:: + + // color.h: + #include + + enum class color {red, green, blue}; + + template <> struct fmt::formatter: formatter { + // parse is inherited from formatter. + + auto format(color c, format_context& ctx) const; + }; + + // color.cc: + #include "color.h" + #include + + auto fmt::formatter::format(color c, format_context& ctx) const { + 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::format(name, ctx); + } + +Note that ``formatter::format`` is defined in ``fmt/format.h`` so +it has to be included in the source file. Since ``parse`` is inherited from +``formatter`` it will recognize all string format specifications, +for example + +.. code-block:: c++ + + fmt::format("{:>10}", color::blue) + +will return ``" blue"``. + +The experimental ``nested_formatter`` provides an easy way of applying a +formatter to one or more subobjects. + +For example:: + + #include + + struct point { + double x, y; + }; + + template <> + struct fmt::formatter : nested_formatter { + auto format(point p, format_context& ctx) const { + return write_padded(ctx, [=](auto out) { + return format_to(out, "({}, {})", nested(p.x), nested(p.y)); + }); + } + }; + + int main() { + fmt::print("[{:>20.2f}]", point{1, 2}); + } + +prints:: + + [ (1.00, 2.00)] + +Notice that fill, align and width are applied to the whole object which is the +recommended behavior while the remaining specifiers apply to elements. + +In general the formatter has the following form:: + + template <> struct fmt::formatter { + // Parses format specifiers and stores them in the formatter. + // + // [ctx.begin(), ctx.end()) is a, possibly empty, character range that + // contains a part of the format string starting from the format + // specifications to be parsed, e.g. in + // + // fmt::format("{:f} continued", ...); + // + // the range will contain "f} continued".
