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 ligthweight, 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/external/CppFormat/LICENSE.rst b/external/CppFormat/LICENSE.rst index b1c96ca0..eb6be650 100644 --- a/external/CppFormat/LICENSE.rst +++ b/external/CppFormat/LICENSE.rst @@ -1,4 +1,4 @@ -Copyright (c) 2012 - 2015, Victor Zverovich +Copyright (c) 2012 - 2016, Victor Zverovich All rights reserved. diff --git a/external/CppFormat/README.rst b/external/CppFormat/README.rst deleted file mode 100644 index 29f43348..00000000 --- a/external/CppFormat/README.rst +++ /dev/null @@ -1,409 +0,0 @@ -C++ Format -========== - -.. image:: https://travis-ci.org/cppformat/cppformat.png?branch=master - :target: https://travis-ci.org/cppformat/cppformat - -.. image:: https://ci.appveyor.com/api/projects/status/qk0bhyhqp1ekpat8 - :target: https://ci.appveyor.com/project/vitaut/cppformat - -.. image:: https://webapi.biicode.com/v1/badges/vitaut/vitaut/cppformat/master?dummy - :target: https://www.biicode.com/vitaut/cppformat - -.. image:: https://badges.gitter.im/Join%20Chat.svg - :alt: Join the chat at https://gitter.im/cppformat/cppformat - :target: https://gitter.im/cppformat/cppformat?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge - -C++ Format is an open-source formatting library for C++. -It can be used as a safe alternative to printf or as a fast -alternative to IOStreams. - -`Documentation `_ - -Features --------- - -* Two APIs: faster concatenation-based write API and slower (but still - very fast) replacement-based format API with positional arguments for - localization. -* Write API similar to the one used by IOStreams but stateless allowing - faster implementation. -* Format API with `format string syntax - `_ - similar to the one used by `str.format - `_ in Python. -* Safe `printf implementation - `_ - including the POSIX extension for positional arguments. -* Support for user-defined types. -* High speed: performance of the format API is close to that of - glibc's `printf `_ - and better than performance of IOStreams.

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 mostly solved 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, referred to this situation with -IOStreams as "chevron hell". IOStreams doesn't support positional arguments -by design. - -The good part is that IOStreams supports user-defined types and is safe -although error reporting is awkward. - -Boost Format library -~~~~~~~~~~~~~~~~~~~~ - -This is a very powerful library which supports both printf-like format -strings and positional arguments. The main its 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. - -Loki SafeFormat -~~~~~~~~~~~~~~~ - -SafeFormat is a formatting library which uses printf-like format strings -and is type safe. It doesn't support user-defined types or positional -arguments. It makes unconventional use of ``operator()`` for passing -format arguments. - -Tinyformat -~~~~~~~~~~ - -This library supports printf-like format strings and is very small and -fast. Unfortunately it doesn't support positional arguments and wrapping -it in C++98 is somewhat difficult. Also its performance and code compactness -are limited by IOStreams. - -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::Writer`` on Karma's own benchmark, -see `Fast integer to string conversion in C++ -`_. - -Benchmarks ----------- - -Speed tests -~~~~~~~~~~~ - -The following speed tests results were generated by building -``tinyformat_test.cpp`` on Ubuntu GNU/Linux 14.04.1 with -``g++-4.8.2 -O3 -DSPEED_TEST -DHAVE_FORMAT``, and taking the best of three -runs.
