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) `_. - -* Removed the following deprecated APIs: ``_format``, ``arg_join``, - the ``format_to`` overload that takes a memory buffer, - ``[v]fprintf`` that takes an ``ostream``. - -* Removed the deprecated implicit conversion of ``[const] signed char*`` and - ``[const] unsigned char*`` to C strings. - -* Removed the deprecated ``fmt/locale.h``. - -* Replaced the deprecated ``fileno()`` with ``descriptor()`` in - ``buffered_file``. - -* Moved ``to_string_view`` to the ``detail`` namespace since it's an - implementation detail. - -* Made access mode of a created file consistent with ``fopen`` by setting - ``S_IWGRP`` and ``S_IWOTH`` - (`#2733 `_). - Thanks `@arogge (Andreas Rogge) `_. - -* Removed a redundant buffer resize when formatting to ``std::ostream`` - (`#2842 `_, - `#2843 `_). - Thanks `@jcelerier (Jean-Michaël Celerier) `_. - -* Made precision computation for strings consistent with width - (`#2888 `_). - -* Fixed handling of locale separators in floating point formatting -

For example: - - .. code:: 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 (Camille Bordignon) `_. - -* Implemented the default format for ``std::chrono::system_clock`` - (`#2319 `_, - `#2345 `_).

Thanks `@sunmy2019 `_. - -* Made more chrono specifiers locale independent by default. Use the ``'L'`` - specifier to get localized formatting. For example: - - .. code:: 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 - (`#2337 `_, - `#2349 `_, - `#2350 `_). - Thanks `@phprus (Vladislav Shchapov) `_. - -* 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`` - (`#2327 `_). - -* Added support for time points with arbitrary durations - (`#2208 `_). For example: - - .. code:: 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: - - .. code:: 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: - - .. code:: 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 - (`#2305 `_, - `#2310 `_). - Thanks `@Liedtke (Matthias Liedtke) `_. - -* Made the hexfloat formatting use the right alignment by default - (`#2308 `_, - `#2317 `_). - Thanks `@Liedtke (Matthias 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 - (`#2133 `_). - -* Added support for the ``'s'`` format specifier that gives textual - representation of ``bool`` - (`#2094 `_, - `#2109 `_). For example: - - .. code:: c++ - - #include - - int main() { - fmt::print("{:s}", true); - } - - prints "true". - Thanks `@powercoderlol (Ivan Polyakov) `_. - -* Made ``fmt::ptr`` work with function pointers - (`#2131 `_). For example: - - .. code:: c++ - - #include - - int main() { - fmt::print("My main: {}\n", fmt::ptr(main)); - } - - Thanks `@mikecrowe (Mike Crowe) `_. - -* The undocumented support for specializing ``formatter`` for pointer types - has been removed. - -* Fixed ``fmt::formatted_size`` with format string compilation - (`#2141 `_, - `#2161 `_). - Thanks `@alexezeder (Alexey Ochapov) `_. - -* Fixed handling of empty format strings during format string compilation - (`#2042 `_): - - .. code:: c++ - - auto s = fmt::format(FMT_COMPILE("")); - - Thanks `@alexezeder (Alexey Ochapov) `_. - -* Fixed handling of enums in ``fmt::to_string`` - (`#2036 `_). - -* Improved width computation - (`#2033 `_, - `#2091 `_). For example: - - .. code:: c++ - - #include - - int main() { - fmt::print("{:-<10}{}\n", "你好", "世界"); - fmt::print("{:-<10}{}\n", "hello", "world"); - } - - prints - - .. image:: 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`` - (`#2018 `_). For example: - - .. code:: 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 - (`#2197 `_, - `#2198 `_). - 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. - Thanks `@phprus (Vladislav Shchapov) `_. - -* Replaced ``fmt::error_code`` with ``std::error_code`` and made it formattable - (`#2269 `_, - `#2270 `_, - `#2273 `_). - Thanks `@phprus (Vladislav Shchapov) `_. - -* Added speech synthesis support - (`#2206 `_). - -* Made ``format_to`` work with a memory buffer that has a custom allocator - (`#2300 `_). - Thanks `@voxmea `_. - -* Added ``Allocator::max_size`` support to ``basic_memory_buffer``. - (`#1960 `_). - Thanks `@phprus (Vladislav Shchapov) `_. - -* Added wide string support to ``fmt::join`` - (`#2236 `_). - Thanks `@crbrz `_. - -* Made iterators passed to ``formatter`` specializations via a format context -

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/Externals/fmt/LICENSE.rst b/Externals/fmt/LICENSE.rst deleted file mode 100755 index f0ec3db4d2..0000000000 --- a/Externals/fmt/LICENSE.rst +++ /dev/null @@ -1,27 +0,0 @@ -Copyright (c) 2012 - present, Victor Zverovich - -Permission is hereby granted, free of charge, to any person obtaining -a copy of this software and associated documentation files (the -"Software"), to deal in the Software without restriction, including -without limitation the rights to use, copy, modify, merge, publish, -distribute, sublicense, and/or sell copies of the Software, and to -permit persons to whom the Software is furnished to do so, subject to -the following conditions: - -The above copyright notice and this permission notice shall be -included in all copies or substantial portions of the Software. - -THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, -EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF -MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND -NONINFRINGEMENT.

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.
