In particular this results in consistent rounding on all platforms - and removing the ``s[n]printf`` fallback for decimal FP formatting. - -* Compile-time floating point formatting no longer requires the header-only - mode.

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::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 -

So ``fmt::Writer`` should be replaced - with ``fmt::MemoryWriter`` in variable declarations. - - Old code: - - .. code:: c++ - - fmt::Writer w; - - New code: - - .. code:: c++ - - fmt::MemoryWriter w; - - If you pass ``fmt::Writer`` by reference, you can continue to do so: - - .. code:: c++ - - void f(fmt::Writer &w); - - This doesn't affect the formatting API. - -* Support for custom memory allocators - (`#69 `_) - -* Formatting functions now accept `signed char` and `unsigned char` strings as - arguments (`#73 `_): - - .. code:: c++ - - auto s = format("GLSL version: {}", glGetString(GL_VERSION)); - -* Reduced code bloat. According to the new `benchmark results - `_, - cppformat is close to ``printf`` and by the order of magnitude better than - Boost Format in terms of compiled code size. - -* Improved appearance of the documentation on mobile by using the `Sphinx - Bootstrap theme `_: - - .. |old| image:: https://cloud.githubusercontent.com/assets/576385/4792130/ - cd256436-5de3-11e4-9a62-c077d0c2b003.png - - .. |new| image:: https://cloud.githubusercontent.com/assets/576385/4792131/ - cd29896c-5de3-11e4-8f59-cac952942bf0.png - - +-------+-------+ - | Old | New | - +-------+-------+ - | |old| | |new| | - +-------+-------+ - -0.11.0 - 2014-08-21 -------------------- - -* Safe printf implementation with a POSIX extension for positional arguments: - - .. code:: c++ - - fmt::printf("Elapsed time: %.2f seconds", 1.23); - fmt::printf("%1$s, %3$d %2$s", weekday, month, day); - -* Arguments of ``char`` type can now be formatted as integers - (Issue `#55 `_): - - .. code:: c++ - - fmt::format("0x{0:02X}", 'a'); - -* Deprecated parts of the API removed. - -* The library is now built and tested on MinGW with Appveyor in addition to - existing test platforms Linux/GCC, OS X/Clang, Windows/MSVC. - -0.10.0 - 2014-07-01 -------------------- - -**Improved API** - -* All formatting methods are now implemented as variadic functions instead - of using ``operator<<`` for feeding arbitrary arguments into a temporary - formatter object. 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/src/base/3rdparty/fmt/LICENSE.rst b/src/base/3rdparty/fmt/LICENSE.rst deleted file mode 100644 index f0ec3db4..00000000 --- a/src/base/3rdparty/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. 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 a3966d14..00000000 --- a/src/base/3rdparty/fmt/args.h +++ /dev/null @@ -1,234 +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.
