-
-*fmt* is a format string that contains literal text and replacement fields

-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

-      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.

-Formatting User-Defined Types
------------------------------
-
-The {fmt} library provides formatters for many standard C++ types.
-See :ref:`fmt/ranges.h <ranges-api>` for ranges and tuples including standard
-containers such as ``std::vector``, :ref:`fmt/chrono.h <chrono-api>` for date
-and time formatting and :ref:`fmt/std.h <std-api>` 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
-
-.. code-block:: c++
-
-   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``.
-
-.. doxygenfunction:: operator""_a()
-
-Utilities
----------
-
-.. doxygenfunction:: fmt::ptr(T p) -> const void*
-.. doxygenfunction:: fmt::ptr(const std::unique_ptr<T> &p) -> const void*
-.. doxygenfunction:: fmt::ptr(const std::shared_ptr<T> &p) -> const void*
-
-.. doxygenfunction:: fmt::underlying(Enum e) -> typename std::underlying_type<Enum>::type

-
-.. doxygenfunction:: fmt::join(Range &&range, string_view sep) -> join_view<detail::iterator_t<Range>, detail::sentinel_t<Range>>
-
-.. doxygenfunction:: fmt::join(It begin, Sentinel end, string_view sep) -> join_view<It, Sentinel>
-
-.. doxygenfunction:: fmt::group_digits(T value) -> group_digits_view<T>
-
-.. doxygenclass:: fmt::detail::buffer
-   :members:
-
-.. doxygenclass:: fmt::basic_memory_buffer
-   :protected-members:
-   :members:
-
-System Errors
--------------
-
-{fmt} does not use ``errno`` to communicate errors to the user, but it may call
-system functions which set ``errno``. Users should not make any assumptions
-about the value of ``errno`` being preserved by library functions.
-
-.. doxygenfunction:: fmt::system_error
-
-.. doxygenfunction:: fmt::format_system_error
-
-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) {
-      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``.
-
-.. _ranges-api:
-
-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, ", "));
-
-.. _chrono-api:
-
-Date and Time Formatting
-========================
-
-``fmt/chrono.h`` provides formatters for
-
-* `std::chrono::duration <https://en.cppreference.com/w/cpp/chrono/duration>`_
-* `std::chrono::time_point
-  <https://en.cppreference.com/w/cpp/chrono/time_point>`_
-* `std::tm <https://en.cppreference.com/w/cpp/chrono/c/tm>`_
-
-The format syntax is described in :ref:`chrono-specs`.
-
-**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);
-  }
-
-.. doxygenfunction:: localtime(std::time_t time)
-
-.. doxygenfunction:: gmtime(std::time_t time)
-
-.. _std-api:
-
-Standard Library Types Formatting
-=================================
-
-``fmt/std.h`` provides formatters for:
-
-* `std::filesystem::path <https://en.cppreference.com/w/cpp/filesystem/path>`_
-* `std::thread::id <https://en.cppreference.com/w/cpp/thread/thread/id>`_
-* `std::monostate <https://en.cppreference.com/w/cpp/utility/variant/monostate>`_
-* `std::variant <https://en.cppreference.com/w/cpp/utility/variant/variant>`_
-
-Formatting Variants
--------------------
-
-A ``std::variant`` is only formattable if every variant alternative is formattable, and requires the
-``__cpp_lib_variant`` `library feature <https://en.cppreference.com/w/cpp/feature_test>`_.
-  
-**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)"
-
-.. _compile-api:
-
-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.
-
-.. doxygendefine:: FMT_COMPILE
-
-.. doxygenfunction:: operator""_cf()
-
-.. _color-api:
-
-Terminal Color and Text Style
-=============================
-
-``fmt/color.h`` provides support for terminal color and text style output.
-
-.. doxygenfunction:: print(const text_style &ts, const S &format_str, const Args&... args)
-
-.. doxygenfunction:: fg(detail::color_type)
-
-.. doxygenfunction:: bg(detail::color_type)
-
-.. doxygenfunction:: styled(const T& value, text_style ts)
-

-.. doxygenclass:: fmt::ostream
-   :members:
-
-.. doxygenfunction:: fmt::windows_error
-   :members:
-
-.. _ostream-api:
-
-``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"
-
-.. doxygenfunction:: streamed(const T &)
-
-.. doxygenfunction:: print(std::ostream &os, format_string<T...> fmt, T&&... args)
-
-.. _printf-api:
-
-``printf`` Formatting
-=====================
-
-The header ``fmt/printf.h`` provides ``printf``-like formatting functionality.
-The following functions use `printf format string syntax
-<https://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 &format_str, const T&... args)
-
-.. doxygenfunction:: fprintf(std::FILE *f, const S &fmt, const T&... args) -> int
-
-.. doxygenfunction:: sprintf(const S&, const T&...)
-
-.. _xchar-api:
-
-``wchar_t`` Support
-===================
-
-The optional header ``fmt/xchar.h`` provides support for ``wchar_t`` and exotic
-character types.
-
-.. doxygenstruct:: fmt::is_char
-
-.. doxygentypedef:: fmt::wstring_view
-
-.. doxygentypedef:: fmt::wformat_context
-
-.. doxygenfunction:: fmt::to_wstring(const T &value)
-
-Compatibility with C++20 ``std::format``
-========================================
-
-{fmt} implements nearly all of the `C++20 formatting library
-<https://en.cppreference.com/w/cpp/utility/format>`_ 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.

-Overview
-========
-
-**{fmt}** is an open-source formatting library providing a fast and safe
-alternative to C stdio and C++ 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 <code>boost::format</code> and
-       <code>loki::SPrintf</code>, and neither felt like the right answer.
-       This does.
-     </div>
-   </div>
-
-.. _format-api-intro:
-
-Format API
-----------
-
-The format API is similar in spirit to the C ``printf`` family of function but
-is safer, simpler and several times `faster
-<https://www.zverovich.net/2020/06/13/fast-int-to-string-revisited.html>`_
-than common standard library implementations.
-The `format string syntax <syntax.html>`_ is similar to the one used by
-`str.format <https://docs.python.org/3/library/stdtypes.html#str.format>`_ in
-Python:
-
-.. code:: c++
-
-  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``:
-
-.. code:: c++
-
-  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:
-
-.. code:: c++
-
-  fmt::print(stderr, "System error code = {}\n", errno);
-
-If you omit the file argument the function will print 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");
-
-You can pass named arguments with ``fmt::arg``:
-
-.. 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++
-
-  using namespace fmt::literals;
-  fmt::print("Hello, {name}! The answer is {number}. Goodbye, {name}.",
-             "name"_a="World", "number"_a=42);
-
-.. _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 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 <api.html#compile-time-format-string-checks>`_ 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. 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, 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:
-
-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
-<https://github.com/fmtlib/fmt/releases/tag/4.1.0>`_ which is maintained and
-only requires C++98.
-
-The output of all formatting functions is consistent across platforms.
-For example,
-
-.. code::
-
-  fmt::print("{}", std::numeric_limits<double>::infinity());
-
-always prints ``inf`` while the output of ``printf`` is platform-dependent.
-
-.. _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 MIT `license <https://github.com/fmtlib/fmt#license>`_ allows
-using the library both in open-source and commercial projects.

-.. _syntax:
-
-********************
-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` | `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 :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:

-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.
-
-.. ifconfig:: False
-
-   The ``','`` option signals the use of a comma for a thousands separator.
-   For a locale aware separator, use the ``'L'`` 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. 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.                                          |

-+=========+==========================================================+
-| ``'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.     |
-+---------+----------------------------------------------------------+
-
-.. 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.                                           |
-   |         |                                                          |

-
-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:
-
-.. productionlist:: sf
-   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]
-
-.. _formatexamples:
-
-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>

-*****
-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 https://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 ...
-
-__ https://en.wikipedia.org/wiki/Library_%28computing%29#Shared_libraries
-
-
-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
-: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)
-
-Usage with build2
-=================
-
-You can use `build2 <https://build2.org>`_, a dependency manager and a
-build-system combined, to use ``fmt``.
-
-Currently this package is available in these package repositories:
-
-- **https://cppget.org/fmt/** for released and published versions.
-- `The git repository with the sources of the build2 package of fmt <https://github.com/build2-packaging/fmt.git>`_
-  for unreleased or custom revisions of ``fmt``.
-
-**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 <https://build2.org/build2-toolchain/doc/build2-toolchain-intro.xhtml>`_.
-
-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``.
-
-Conda
-=====
-
-fmt can be installed on Linux, macOS and Windows with
-`Conda <https://docs.conda.io/en/latest/>`__, using its
-`conda-forge <https://conda-forge.org>`__
-`package <https://github.com/conda-forge/fmt-feedstock>`__, as follows::
-
-  conda install -c conda-forge fmt
-
-Vcpkg
-=====
-
-You can download and install fmt using the `vcpkg
-<https://github.com/Microsoft/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 <https://github.com/Microsoft/vcpkg>`__ on the vcpkg repository.
-
-LHelper
-=======
-
-You can download and install fmt using
-`lhelper <https://github.com/franko/lhelper>`__ dependency manager::
-
-  lhelper activate <some-environment>
-  lhelper install fmt
-
-All the recipes for lhelper are kept in the
-`lhelper's recipe <https://github.com/franko/lhelper-recipes>`__ repository.
-
-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/support/Android.mk
-
-Homebrew
-========
-
-fmt can be installed on OS X using `Homebrew <https://brew.sh/>`_::
-
-  brew install fmt

-<h1>Overview<a class="headerlink" href="#overview" title="Permalink to this headline">¶</a></h1>
-<p><strong>{fmt}</strong> is an open-source formatting library providing a fast and safe
-alternative to C stdio and C++ iostreams.</p>
-<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 <code>boost::format</code> and
-    <code>loki::SPrintf</code>, and neither felt like the right answer.
-    This does.

-<span id="format-api-intro"></span><h2>Format API<a class="headerlink" href="#format-api" title="Permalink to this headline">¶</a></h2>
-<p>The format API is similar in spirit to the C <code class="docutils literal notranslate"><span class="pre">printf</span></code> family of function but
-is safer, simpler and several times <a class="reference external" href="https://www.zverovich.net/2020/06/13/fast-int-to-string-revisited.html">faster</a>
-than common standard library implementations.
-The <a class="reference external" href="syntax.html">format string syntax</a> is similar to the one used by
-<a class="reference external" href="https://docs.python.org/3/library/stdtypes.html#str.format">str.format</a> in
-Python:</p>
-<div class="highlight-c++ notranslate"><div class="highlight"><pre><span></span><span class="n">std</span><span class="o">::</span><span class="n">string</span><span class="w"> </span><span class="n">s</span><span class="w"> </span><span class="o">=</span><span class="w"> </span><span class="n">fmt</span><span class="o">::</span><span class="n">format</span><span class="p">(</span><span class="s">&quot;The answer is {}.&quot;</span><span class="p">,</span><span class="w"> </span><span class="mi">42</span><span class="p">);</span><span class="w"></span>
-</pre></div>
-</div>
-<p>The <code class="docutils literal notranslate"><span class="pre">fmt::format</span></code> function returns a string “The answer is 42.”. You can use
-<code class="docutils literal notranslate"><span class="pre">fmt::memory_buffer</span></code> to avoid constructing <code class="docutils literal notranslate"><span class="pre">std::string</span></code>:</p>
-<div class="highlight-c++ notranslate"><div class="highlight"><pre><span></span><span class="k">auto</span><span class="w"> </span><span class="n">out</span><span class="w"> </span><span class="o">=</span><span class="w"> </span><span class="n">fmt</span><span class="o">::</span><span class="n">memory_buffer</span><span class="p">();</span><span class="w"></span>

-<span class="k">auto</span><span class="w"> </span><span class="n">data</span><span class="w"> </span><span class="o">=</span><span class="w"> </span><span class="n">out</span><span class="p">.</span><span class="n">data</span><span class="p">();</span><span class="w"> </span><span class="c1">// pointer to the formatted data</span>

-</pre></div>
-</div>
-<p>The <code class="docutils literal notranslate"><span class="pre">fmt::print</span></code> function performs formatting and writes the result to a stream:</p>
-<div class="highlight-c++ notranslate"><div class="highlight"><pre><span></span><span class="n">fmt</span><span class="o">::</span><span class="n">print</span><span class="p">(</span><span class="n">stderr</span><span class="p">,</span><span class="w"> </span><span class="s">&quot;System error code = {}</span><span class="se">\n</span><span class="s">&quot;</span><span class="p">,</span><span class="w"> </span><span class="n">errno</span><span class="p">);</span><span class="w"></span>
-</pre></div>
-</div>
-<p>If you omit the file argument the function will print to <code class="docutils literal notranslate"><span class="pre">stdout</span></code>:</p>
-<div class="highlight-c++ notranslate"><div class="highlight"><pre><span></span><span class="n">fmt</span><span class="o">::</span><span class="n">print</span><span class="p">(</span><span class="s">&quot;Don&#39;t {}</span><span class="se">\n</span><span class="s">&quot;</span><span class="p">,</span><span class="w"> </span><span class="s">&quot;panic&quot;</span><span class="p">);</span><span class="w"></span>
-</pre></div>
-</div>
-<p>The format API also supports positional arguments useful for localization:</p>
-<div class="highlight-c++ notranslate"><div class="highlight"><pre><span></span><span class="n">fmt</span><span class="o">::</span><span class="n">print</span><span class="p">(</span><span class="s">&quot;I&#39;d rather be {1} than {0}.&quot;</span><span class="p">,</span><span class="w"> </span><span class="s">&quot;right&quot;</span><span class="p">,</span><span class="w"> </span><span class="s">&quot;happy&quot;</span><span class="p">);</span><span class="w"></span>
-</pre></div>
-</div>
-<p>You can pass named arguments with <code class="docutils literal notranslate"><span class="pre">fmt::arg</span></code>:</p>
-<div class="highlight-c++ notranslate"><div class="highlight"><pre><span></span><span class="n">fmt</span><span class="o">::</span><span class="n">print</span><span class="p">(</span><span class="s">&quot;Hello, {name}! The answer is {number}. Goodbye, {name}.&quot;</span><span class="p">,</span><span class="w"></span>
-<span class="w">           </span><span class="n">fmt</span><span class="o">::</span><span class="n">arg</span><span class="p">(</span><span class="s">&quot;name&quot;</span><span class="p">,</span><span class="w"> </span><span class="s">&quot;World&quot;</span><span class="p">),</span><span class="w"> </span><span class="n">fmt</span><span class="o">::</span><span class="n">arg</span><span class="p">(</span><span class="s">&quot;number&quot;</span><span class="p">,</span><span class="w"> </span><span class="mi">42</span><span class="p">));</span><span class="w"></span>
-</pre></div>
-</div>
-<p>If your compiler supports C++11 user-defined literals, the suffix <code class="docutils literal notranslate"><span class="pre">_a</span></code> offers
-an alternative, slightly terser syntax for named arguments:</p>
-<div class="highlight-c++ notranslate"><div class="highlight"><pre><span></span><span class="k">using</span><span class="w"> </span><span class="k">namespace</span><span class="w"> </span><span class="nn">fmt</span><span class="o">::</span><span class="nn">literals</span><span class="p">;</span><span class="w"></span>
-<span class="n">fmt</span><span class="o">::</span><span class="n">print</span><span class="p">(</span><span class="s">&quot;Hello, {name}! The answer is {number}. Goodbye, {name}.&quot;</span><span class="p">,</span><span class="w"></span>
-<span class="w">           </span><span class="s">&quot;name&quot;</span><span class="n">_a</span><span class="o">=</span><span class="s">&quot;World&quot;</span><span class="p">,</span><span class="w"> </span><span class="s">&quot;number&quot;</span><span class="n">_a</span><span class="o">=</span><span class="mi">42</span><span class="p">);</span><span class="w"></span>

-<span id="id1"></span><h2>Safety<a class="headerlink" href="#safety" title="Permalink to this headline">¶</a></h2>
-<p>The library is fully type safe, automatic memory management prevents buffer
-overflow, errors in format strings are reported using exceptions or at compile

-<div class="highlight-c++ notranslate"><div class="highlight"><pre><span></span><span class="n">fmt</span><span class="o">::</span><span class="n">format</span><span class="p">(</span><span class="s">&quot;The answer is {:d}&quot;</span><span class="p">,</span><span class="w"> </span><span class="s">&quot;forty-two&quot;</span><span class="p">);</span><span class="w"></span>
-</pre></div>
-</div>
-<p>throws the <code class="docutils literal notranslate"><span class="pre">format_error</span></code> exception because the argument <code class="docutils literal notranslate"><span class="pre">&quot;forty-two&quot;</span></code> is a

-<code class="docutils literal notranslate"><span class="pre">std::ostream</span></code> results in its numeric value being written to the stream
-(i.e. 1070 instead of letter ‘ю’ which is represented by <code class="docutils literal notranslate"><span class="pre">L'\x42e'</span></code> if we

-<p>Formatting functions such as <a class="reference internal" href="api.html#format"><span class="std std-ref">fmt::format()</span></a> and
-<a class="reference internal" href="api.html#print"><span class="std std-ref">fmt::print()</span></a> use the same format string syntax described in this
-section.</p>
-<p>Format strings contain “replacement fields” surrounded by curly braces <code class="docutils literal notranslate"><span class="pre">{}</span></code>.
-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: <code class="docutils literal notranslate"><span class="pre">{{</span></code> and <code class="docutils literal notranslate"><span class="pre">}}</span></code>.</p>
-<p>The grammar for a replacement field is as follows:</p>
-<pre>
-<strong id="grammar-token-sf-replacement_field"><span id="grammar-token-replacement-field"></span>replacement_field</strong> ::=  &quot;{&quot; [<a class="reference internal" href="#grammar-token-sf-arg_id"><code class="xref docutils literal notranslate"><span class="pre">arg_id</span></code></a>] [&quot;:&quot; (<a class="reference internal" href="#grammar-token-sf-format_spec"><code class="xref docutils literal notranslate"><span class="pre">format_spec</span></code></a> | <a class="reference internal" href="#grammar-token-sf-chrono_format_spec"><code class="xref docutils literal notranslate"><span class="pre">chrono_format_spec</span></code></a>)] &quot;}&quot;
-<strong id="grammar-token-sf-arg_id"><span id="grammar-token-arg-id"></span>arg_id           </strong> ::=  <a class="reference internal" href="#grammar-token-sf-integer"><code class="xref docutils literal notranslate"><span class="pre">integer</span></code></a> | <a class="reference internal" href="#grammar-token-sf-identifier"><code class="xref docutils literal notranslate"><span class="pre">identifier</span></code></a>

-<strong id="grammar-token-sf-digit"><span id="grammar-token-digit"></span>digit            </strong> ::=  &quot;0&quot;...&quot;9&quot;
-<strong id="grammar-token-sf-identifier"><span id="grammar-token-identifier"></span>identifier       </strong> ::=  <a class="reference internal" href="#grammar-token-sf-id_start"><code class="xref docutils literal notranslate"><span class="pre">id_start</span></code></a> <a class="reference internal" href="#grammar-token-sf-id_continue"><code class="xref docutils literal notranslate"><span class="pre">id_continue</span></code></a>*
-<strong id="grammar-token-sf-id_start"><span id="grammar-token-id-start"></span>id_start         </strong> ::=  &quot;a&quot;...&quot;z&quot; | &quot;A&quot;...&quot;Z&quot; | &quot;_&quot;
-<strong id="grammar-token-sf-id_continue"><span id="grammar-token-id-continue"></span>id_continue      </strong> ::=  <a class="reference internal" href="#grammar-token-sf-id_start"><code class="xref docutils literal notranslate"><span class="pre">id_start</span></code></a> | <a class="reference internal" href="#grammar-token-sf-digit"><code class="xref docutils literal notranslate"><span class="pre">digit</span></code></a>
-</pre>
-<p>In less formal terms, the replacement field can start with an <em>arg_id</em>
-that specifies the argument whose value is to be formatted and inserted into
-the output instead of the replacement field.
-The <em>arg_id</em> is optionally followed by a <em>format_spec</em>, which is preceded by a
-colon <code class="docutils literal notranslate"><span class="pre">':'</span></code>.  These specify a non-default format for the replacement value.</p>
-<p>See also the <a class="reference internal" href="#formatspec"><span class="std std-ref">Format Specification Mini-Language</span></a> section.</p>
-<p>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.</p>
-<p>Named arguments can be referred to by their names or indices.</p>
-<p>Some simple format string examples:</p>
-<div class="highlight-c++ notranslate"><div class="highlight"><pre><span></span><span class="s">&quot;First, thou shalt count to {0}&quot;</span><span class="w"> </span><span class="c1">// References the first argument</span>
-<span class="s">&quot;Bring me a {}&quot;</span><span class="w">                  </span><span class="c1">// Implicitly references the first argument</span>
-<span class="s">&quot;From {} to {}&quot;</span><span class="w">                  </span><span class="c1">// Same as &quot;From {0} to {1}&quot;</span>
-</pre></div>
-</div>
-<p>The <em>format_spec</em> 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 <em>format_spec</em>.</p>
-<p>Most built-in types support a common formatting mini-language, which is
-described in the next section.</p>
-<p>A <em>format_spec</em> 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.</p>
-<p>See the <a class="reference internal" href="#formatexamples"><span class="std std-ref">Format Examples</span></a> section for some examples.</p>

-<p>“Format specifications” are used within replacement fields contained within a
-format string to define how individual values are presented (see
-<a class="reference internal" href="#syntax"><span class="std std-ref">Format String Syntax</span></a>).  Each formattable type may define how the format
-specification is to be interpreted.</p>
-<p>Most built-in types implement the following options for format specifications,
-although some of the formatting options are only supported by the numeric types.</p>
-<p>The general form of a <em>standard format specifier</em> is:</p>

-                 &quot;o&quot; | &quot;p&quot; | &quot;s&quot; | &quot;x&quot; | &quot;X&quot;
-</pre>
-<p>The <em>fill</em> character can be any Unicode code point other than <code class="docutils literal notranslate"><span class="pre">'{'</span></code> or
-<code class="docutils literal notranslate"><span class="pre">'}'</span></code>. 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
-<em>format_spec</em> is not a valid alignment option, then it is assumed that both the
-fill character and the alignment option are absent.</p>
-<p>The meaning of the various alignment options is as follows:</p>
-<table class="docutils align-default">
-<colgroup>
-<col style="width: 13%" />
-<col style="width: 87%" />
-</colgroup>
-<thead>
-<tr class="row-odd"><th class="head"><p>Option</p></th>

-<tr class="row-even"><td><p><code class="docutils literal notranslate"><span class="pre">'&lt;'</span></code></p></td>
-<td><p>Forces the field to be left-aligned within the available

-</tr>
-<tr class="row-odd"><td><p><code class="docutils literal notranslate"><span class="pre">'&gt;'</span></code></p></td>
-<td><p>Forces the field to be right-aligned within the
-available space (this is the default for numbers).</p></td>
-</tr>
-<tr class="row-even"><td><p><code class="docutils literal notranslate"><span class="pre">'^'</span></code></p></td>
-<td><p>Forces the field to be centered within the available
-space.</p></td>
-</tr>
-</tbody>
-</table>
-<p>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.</p>
-<p>The <em>sign</em> option is only valid for number types, and can be one of the
-following:</p>
-<table class="docutils align-default">
-<colgroup>
-<col style="width: 13%" />
-<col style="width: 87%" />
-</colgroup>
-<thead>
-<tr class="row-odd"><th class="head"><p>Option</p></th>
-<th class="head"><p>Meaning</p></th>
-</tr>
-</thead>
-<tbody>
-<tr class="row-even"><td><p><code class="docutils literal notranslate"><span class="pre">'+'</span></code></p></td>
-<td><p>indicates that a sign should be used for both
-nonnegative as well as negative numbers.</p></td>
-</tr>
-<tr class="row-odd"><td><p><code class="docutils literal notranslate"><span class="pre">'-'</span></code></p></td>
-<td><p>indicates that a sign should be used only for negative
-numbers (this is the default behavior).</p></td>
-</tr>
-<tr class="row-even"><td><p>space</p></td>
-<td><p>indicates that a leading space should be used on
-nonnegative numbers, and a minus sign on negative numbers.</p></td>
-</tr>
-</tbody>
-</table>
-<p>The <code class="docutils literal notranslate"><span class="pre">'#'</span></code> 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 <code class="docutils literal notranslate"><span class="pre">&quot;0b&quot;</span></code> (<code class="docutils literal notranslate"><span class="pre">&quot;0B&quot;</span></code>), <code class="docutils literal notranslate"><span class="pre">&quot;0&quot;</span></code>, or
-<code class="docutils literal notranslate"><span class="pre">&quot;0x&quot;</span></code> (<code class="docutils literal notranslate"><span class="pre">&quot;0X&quot;</span></code>) 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 <code class="docutils literal notranslate"><span class="pre">&quot;0x&quot;</span></code> is used for the type <code class="docutils literal notranslate"><span class="pre">'x'</span></code>
-and <code class="docutils literal notranslate"><span class="pre">&quot;0X&quot;</span></code> is used for <code class="docutils literal notranslate"><span class="pre">'X'</span></code>.  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 <code class="docutils literal notranslate"><span class="pre">'g'</span></code> and <code class="docutils literal notranslate"><span class="pre">'G'</span></code>
-conversions, trailing zeros are not removed from the result.</p>
-<p><em>width</em> is a decimal integer defining the minimum field width.  If not
-specified, then the field width will be determined by the content.</p>
-<p>Preceding the <em>width</em> field by a zero (<code class="docutils literal notranslate"><span class="pre">'0'</span></code>) 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.</p>
-<p>The <em>precision</em> is a decimal number indicating how many digits should be
-displayed after the decimal point for a floating-point value formatted with
-<code class="docutils literal notranslate"><span class="pre">'f'</span></code> and <code class="docutils literal notranslate"><span class="pre">'F'</span></code>, or before and after the decimal point for a floating-point
-value formatted with <code class="docutils literal notranslate"><span class="pre">'g'</span></code> or <code class="docutils literal notranslate"><span class="pre">'G'</span></code>.  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 <em>precision</em> is not allowed for integer,
-character, Boolean, and pointer values. Note that a C string must be
-null-terminated even if precision is specified.</p>
-<p>The <code class="docutils literal notranslate"><span class="pre">'L'</span></code> option uses the current locale setting to insert the appropriate
-number separator characters. This option is only valid for numeric types.</p>
-<p>Finally, the <em>type</em> determines how the data should be presented.</p>

-<h2>Range Format Specifications<a class="headerlink" href="#range-format-specifications" title="Permalink to this headline">¶</a></h2>
-<p>Format specifications for range types have the following syntax:</p>
-<pre>
-<strong id="grammar-token-sf-range_format_spec"><span id="grammar-token-range-format-spec"></span>range_format_spec</strong> ::=  [&quot;:&quot; [<code class="xref docutils literal notranslate"><span class="pre">underlying_spec</span></code>]]
-</pre>
-<p>The <code class="xref cpp cpp-any docutils literal notranslate"><span class="pre">underlying_spec</span></code> is parsed based on the formatter of the range’s
-reference type.</p>
-<p>By default, a range of characters or strings is printed escaped and quoted. But
-if any <code class="xref cpp cpp-any docutils literal notranslate"><span class="pre">underlying_spec</span></code> is provided (even if it is empty), then the characters
-or strings are printed according to the provided specification.</p>

-<p>This section contains examples of the format syntax and comparison with
-the printf formatting.</p>
-<p>In most of the cases the syntax is similar to the printf formatting, with the
-addition of the <code class="docutils literal notranslate"><span class="pre">{}</span></code> and with <code class="docutils literal notranslate"><span class="pre">:</span></code> used instead of <code class="docutils literal notranslate"><span class="pre">%</span></code>.
-For example, <code class="docutils literal notranslate"><span class="pre">&quot;%03.2f&quot;</span></code> can be translated to <code class="docutils literal notranslate"><span class="pre">&quot;{:03.2f}&quot;</span></code>.</p>
-<p>The new format syntax also supports new and different options, shown in the
-following examples.</p>

-<code class="file docutils literal notranslate"><span class="pre">fmt/format-inl.h</span></code>, <code class="file docutils literal notranslate"><span class="pre">src/format.cc</span></code> and optionally other headers

-<span id="building"></span><h2>Building the Library<a class="headerlink" href="#building-the-library" title="Permalink to this headline">¶</a></h2>
-<p>The included <a class="reference external" href="https://github.com/fmtlib/fmt/blob/master/CMakeLists.txt">CMake build script</a> can be used to build the fmt
-library on a wide range of platforms. CMake is freely available for
-download from <a class="reference external" href="https://www.cmake.org/download/">https://www.cmake.org/download/</a>.</p>
-<p>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:</p>
-<div class="highlight-c++ notranslate"><div class="highlight"><pre><span></span>mkdir build          # Create a directory to hold the build output.
-cd build
-cmake ..  # Generate native build scripts.
-</pre></div>

-<p>where <code class="file docutils literal notranslate"><em><span class="pre">&lt;path/to/fmt&gt;</span></em></code> is a path to the <code class="docutils literal notranslate"><span class="pre">fmt</span></code> repository.</p>
-<p>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 <strong class="command">make</strong>.</p>
-<p>Once the library has been built you can invoke <strong class="command">make test</strong> to run
-the tests.</p>
-<p>You can control generation of the make <code class="docutils literal notranslate"><span class="pre">test</span></code> target with the <code class="docutils literal notranslate"><span class="pre">FMT_TEST</span></code>
-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 <code class="docutils literal notranslate"><span class="pre">test</span></code> target.</p>
-<p>If you use Windows and have Visual Studio installed, a <code class="file docutils literal notranslate"><span class="pre">FMT.sln</span></code>
-file and several <code class="file docutils literal notranslate"><span class="pre">.vcproj</span></code> files will be created. You can then build them
-using Visual Studio or msbuild.</p>
-<p>On Mac OS X with Xcode installed, an <code class="file docutils literal notranslate"><span class="pre">.xcodeproj</span></code> file will be generated.</p>
