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 <https://github.com/cppformat/cppformat/issues/69>`_) + +* Formatting functions now accept `signed char` and `unsigned char` strings as + arguments (`#73 <https://github.com/cppformat/cppformat/issues/73>`_): + + .. code:: c++ + + auto s = format("GLSL version: {}", glGetString(GL_VERSION)); + +* Reduced code bloat. According to the new `benchmark results + <https://github.com/cppformat/cppformat#compile-time-and-code-bloat>`_, + 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 <http://ryan-roemer.github.io/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 <https://github.com/cppformat/cppformat/issues/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 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 <https://github.com/cppformat/cppformat/issues/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 '<filename>': 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/dep/cppformat/LICENSE b/dep/cppformat/LICENSE new file mode 100644 index 00000000000..2ee9ec93495 --- /dev/null +++ b/dep/cppformat/LICENSE @@ -0,0 +1,22 @@ +Copyright (c) 2014 - 2015, Victor Zverovich +All rights reserved. + +Redistribution and use in source and binary forms, with or without +modification, are permitted provided that the following conditions are met: + +1.
