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 based on the one from Python `string module +documentation `_. +For this reason the documentation is distributed under the Python Software +Foundation license available in `doc/python-license.txt +`_. +It only applies if you distribute the documentation of {fmt}. + +Maintainers +----------- + +The {fmt} library is maintained by Victor Zverovich (`vitaut +`_) and Jonathan Müller (`foonathan +`_) with contributions from many other people. +See `Contributors `_ and +`Releases `_ for some of the names. +Let us know if your contribution is not listed or mentioned incorrectly and +we'll make it right. diff --git a/src/3rdparty/fmt/chrono.h b/src/3rdparty/fmt/chrono.h new file mode 100644 index 00000000..1a3b8d5e --- /dev/null +++ b/src/3rdparty/fmt/chrono.h @@ -0,0 +1,1118 @@ +// Formatting library for C++ - chrono support +// +// Copyright (c) 2012 - present, Victor Zverovich +// All rights reserved. +// +// For the license information refer to format.h. + +#ifndef FMT_CHRONO_H_ +#define FMT_CHRONO_H_ + +#include +#include +#include +#include + +#include "format.h" +#include "locale.h" + +FMT_BEGIN_NAMESPACE + +// Enable safe chrono durations, unless explicitly disabled. +#ifndef FMT_SAFE_DURATION_CAST +# define FMT_SAFE_DURATION_CAST 1 +#endif +#if FMT_SAFE_DURATION_CAST + +// For conversion between std::chrono::durations without undefined +// behaviour or erroneous results. +// This is a stripped down version of duration_cast, for inclusion in fmt. +// See https://github.com/pauldreik/safe_duration_cast +// +// Copyright Paul Dreik 2019 +namespace safe_duration_cast { + +template ::value && + std::numeric_limits::is_signed == + std::numeric_limits::is_signed)> +FMT_CONSTEXPR To lossless_integral_conversion(const From from, int& ec) { + ec = 0; + using F = std::numeric_limits; + using T = std::numeric_limits; + static_assert(F::is_integer, "From must be integral"); + static_assert(T::is_integer, "To must be integral"); + + // A and B are both signed, or both unsigned. + if (F::digits <= T::digits) { + // From fits in To without any problem. + } else { + // From does not always fit in To, resort to a dynamic check. + if (from < (T::min)() || from > (T::max)()) { + // outside range. + ec = 1; + return {}; + } + } + return static_cast(from); +} + +/** + * converts From to To, without loss.
