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/base/3rdparty/fmt/args.h b/src/base/3rdparty/fmt/args.h deleted file mode 100644 index 562e8ab11..000000000 --- a/src/base/3rdparty/fmt/args.h +++ /dev/null @@ -1,232 +0,0 @@ -// Formatting library for C++ - dynamic format arguments -// -// Copyright (c) 2012 - present, Victor Zverovich -// All rights reserved. -// -// For the license information refer to format.h. - -#ifndef FMT_ARGS_H_ -#define FMT_ARGS_H_ - -#include // std::reference_wrapper -#include // std::unique_ptr -#include - -#include "core.h" - -FMT_BEGIN_NAMESPACE - -namespace detail { - -template struct is_reference_wrapper : std::false_type {}; -template -struct is_reference_wrapper> : std::true_type {}; - -template const T& unwrap(const T& v) { return v; } -template const T& unwrap(const std::reference_wrapper& v) { - return static_cast(v); -} - -class dynamic_arg_list { - // Workaround for clang's -Wweak-vtables.
