3.0.0 - TBD
|
|
-----------
|
|
|
|
* The project has been renamed from C++ Format (cppformat) to fmt for
|
|
consistency with the used namespace and macro prefix
|
|
(`#307 <https://github.com/fmtlib/fmt/issues/307>`_).
|
|
Library headers are now located in the ``fmt`` directory:
|
|
|
|
.. code:: c++
|
|
|
|
#include "fmt/format.h"
|
|
|
|
Including ``format.h`` from the ``cppformat`` directory is deprecated
|
|
but works via a proxy header which will be removed in the next major version.
|
|
|
|
* Added support for `strftime <http://en.cppreference.com/w/cpp/chrono/c/strftime>`_-like
|
|
`date and time formatting <http://fmtlib.net/dev/api.html#date-and-time-formatting>`_
|
|
(`#283 <https://github.com/fmtlib/fmt/issues/283>`_):
|
|
|
|
.. code:: c++
|
|
|
|
#include "fmt/time.h"
|
|
|
|
std::time_t t = std::time(nullptr);
|
|
// Prints "The date is 2016-04-29." (with the current date)
|
|
fmt::print("The date is {:%Y-%m-%d}.", *std::localtime(&t));
|
|
|
|
* ``std::ostream`` support including formatting of user-defined types that provide
|
|
overloaded ``operator<<`` has been moved to ``fmt/ostream.h``:
|
|
|
|
.. code:: c++
|
|
|
|
#include "fmt/ostream.h"
|
|
|
|
class Date {
|
|
int year_, month_, day_;
|
|
public:
|
|
Date(int year, int month, int day) : year_(year), month_(month), day_(day) {}
|
|
|
|
friend std::ostream &operator<<(std::ostream &os, const Date &d) {
|
|
return os << d.year_ << '-' << d.month_ << '-' << d.day_;
|
|
}
|
|
};
|
|
|
|
std::string s = fmt::format("The date is {}", Date(2012, 12, 9));
|
|
// s == "The date is 2012-12-9"
|
|
|
|
* Added support for `custom argument formatters
|
|
<http://fmtlib.net/dev/api.html#argument-formatters>`_
|
|
(`#235 <https://github.com/fmtlib/fmt/issues/235>`_).
|
|
|
|
* Added support for locale-specific integer formatting with the ``n`` specifier
|
|
(`#305 <https://github.com/fmtlib/fmt/issues/305>`_):
|
|
|
|
.. code:: c++
|
|
|
|
std::setlocale(LC_ALL, "en_US.utf8");
|
|
fmt::print("cppformat: {:n}\n", 1234567); // prints 1,234,567
|
|
|
|
* Sign is now preserved when formatting an integer with an incorrect ``printf``
|
|
format specifier (`#265 <https://github.com/fmtlib/fmt/issues/265>`_):
|
|
|
|
.. code:: c++
|
|
|
|
fmt::printf("%lld", -42); // prints -42
|
|
|
|
Note that it would be an undefined behavior in ``std::printf``.
|
|
|
|
* Length modifiers such as `ll` are now optional in printf formatting
|
|
functions and the correct type is determined automatically
|
|
(`#255 <https://github.com/fmtlib/fmt/issues/255>`_):
|
|
|
|
.. code:: c++
|
|
|
|
fmt::printf("%d", std::numeric_limits<long long>::max());
|
|
|
|
Note that it would be an undefined behavior in ``std::printf``.
|
|
|
|
* Added initial support for custom formatters
|
|
(`#231 <https://github.com/fmtlib/fmt/issues/231>`_).
|
|
|
|
* Fixed detection of user-defined literal support on Intel C++ compiler
|
|
(`#311 <https://github.com/fmtlib/fmt/issues/311>`_,
|
|
`#312 <https://github.com/fmtlib/fmt/pull/312>`_).

------------------
|
|
|
|
* Project layout and build system improvements

|
|
major version.
|
|
|
|
* C++ Format CMake targets now have proper interface definitions.
|
|
|
|
* Installed version of the library now supports the header-only
|
|
configuration.
|
|
|
|
* Targets ``doc``, ``install``, and ``test`` are now disabled if C++ Format

Thanks to `@Shauren <https://github.com/Shauren>`_.
|
|
|
|

|
|
|
.. code:: c++
|
|
|
|
fmt::print("{:d}", true); // prints "1"
|
|
|
|
* ``fmt::printf`` and ``fmt::sprintf`` now support formatting of ``bool`` with the
|
|
``%s`` specifier giving textual output, "true" or "false"

* [Breaking] ``fmt::(s)printf`` now supports formatting of objects of user-defined types
|
|
that provide an overloaded ``std::ostream`` insertion operator (``operator<<``)
|
|
(`#201 <https://github.com/fmtlib/fmt/issues/201>`_):
|
|
|
|
.. code:: c++
|
|
|
|
fmt::printf("The date is %s", Date(2012, 12, 9));
|
|
|
|
* [Breaking] The ``Buffer`` template is now part of the public API and can be used
|
|
to implement custom memory buffers

(`#100 <https://github.com/fmtlib/fmt/issues/100>`_,
|
|
`#159 <https://github.com/fmtlib/fmt/issues/159>`_,
|
|
`#183 <https://github.com/fmtlib/fmt/issues/183>`_):

|
|
|
- Comparison operators now compare string content, not pointers
|
|
- ``BasicStringRef::c_str`` replaced by ``BasicStringRef::data``
|

|
``BasicCStringRef``.
|
|
|
|
* Dependency on pthreads introduced by Google Test is now optional
|
|
(`#185 <https://github.com/fmtlib/fmt/issues/185>`_).

|
|
`#198 <https://github.com/fmtlib/fmt/issues/198>`_,

|
|
Thanks to `@alfps (Alf P. Steinbach) <https://github.com/alfps>`_.
|
|
|
|
* [Breaking] ``windows.h`` is now included with ``NOMINMAX`` unless

is defined as 0 before including ``format.h``
|
|
(`#205 <https://github.com/fmtlib/fmt/issues/205>`_,
|
|
`#208 <https://github.com/fmtlib/fmt/pull/208>`_).
|
|
Thanks to `@JodiTheTigger <https://github.com/JodiTheTigger>`_.
|
|
|
|
* Improved detection of ``isnan``, ``isinf`` and ``signbit``.
|

|
|
Optimization
|
|
~~~~~~~~~~~~
|
|
|
|
* Made formatting of user-defined types more efficient with a custom stream buffer
|
|
(`#92 <https://github.com/fmtlib/fmt/issues/92>`_,
|
|
`#230 <https://github.com/fmtlib/fmt/pull/230>`_).
|
|
Thanks to `@NotImplemented <https://github.com/NotImplemented>`_.
|
|
|
|
* Further improved performance of ``fmt::Writer`` on integer formatting
|
|
and fixed a minor regression. Now it is ~7% faster than ``karma::generate``
|
|
on Karma's benchmark
|
|
(`#186 <https://github.com/fmtlib/fmt/issues/186>`_).
|
|
|
|
* [Breaking] Reduced `compiled code size
|
|
<https://github.com/fmtlib/fmt#compile-time-and-code-bloat>`_
|
|
(`#143 <https://github.com/fmtlib/fmt/issues/143>`_,

|
|
Thanks to `@jackyf (Eugene V. Lyubimkin) <https://github.com/jackyf>`_.
|
|
|
|
* [Breaking] Changed the library name from ``format`` to ``cppformat``
|
|
for consistency with the project name and to avoid potential conflicts
|
|
(`#178 <https://github.com/fmtlib/fmt/issues/178>`_).
|
|
Thanks to `@jackyf (Eugene V. Lyubimkin) <https://github.com/jackyf>`_.

(`#103 <https://github.com/fmtlib/fmt/issues/103>`_).
|
|
|
|
1.0.0 - 2015-02-05
|
|
------------------
|
|
|
|
* Add support for a header-only configuration when ``FMT_HEADER_ONLY`` is
|
|
defined before including ``format.h``:
|
|
|
|
.. code:: c++
|
|
|
|
#define FMT_HEADER_ONLY
|
|
#include "format.h"
|
|
|
|
* Compute string length in the constructor of ``BasicStringRef``
|
|
instead of the ``size`` method
|
|
(`#79 <https://github.com/fmtlib/fmt/issues/79>`_).
|
|
This eliminates size computation for string literals on reasonable optimizing
|
|
compilers.
|
|
|
|
* Fix formatting of types with overloaded ``operator <<`` for ``std::wostream``
|
|
(`#86 <https://github.com/fmtlib/fmt/issues/86>`_):
|
|
|
|
.. code:: c++
|
|
|
|
fmt::format(L"The date is {0}", Date(2012, 12, 9));
|
|
|
|
* Fix linkage of tests on Arch Linux
|
|
(`#89 <https://github.com/fmtlib/fmt/issues/89>`_).
|
|
|
|
* Allow precision specifier for non-float arguments
|
|
(`#90 <https://github.com/fmtlib/fmt/issues/90>`_):
|
|
|
|
.. code:: c++
|
|
|
|
fmt::print("{:.3}\n", "Carpet"); // prints "Car"
|
|
|
|
* Fix build on Android NDK
|
|
(`#93 <https://github.com/fmtlib/fmt/issues/93>`_)
|
|
|
|
* Improvements to documentation build procedure.
|
|
|
|
* Remove ``FMT_SHARED`` CMake variable in favor of standard `BUILD_SHARED_LIBS
|
|
<http://www.cmake.org/cmake/help/v3.0/variable/BUILD_SHARED_LIBS.html>`_.
|
|
|
|
* Fix error handling in ``fmt::fprintf``.
|
|
|
|
* Fix a number of warnings.
|
|
|
|
0.12.0 - 2014-10-25
|
|
-------------------
|
|
|
|
* [Breaking] Improved separation between formatting and buffer management.
|
|
``Writer`` is now a base class that cannot be instantiated directly.
|
|
The new ``MemoryWriter`` class implements the default buffer management
|
|
with small allocations done on stack. 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/fmtlib/fmt/issues/69>`_)
|
|
|
|
* Formatting functions now accept `signed char` and `unsigned char` strings as
|
|
arguments (`#73 <https://github.com/fmtlib/fmt/issues/73>`_):
|
|
|
|
.. code:: c++
|
|
|
|
auto s = format("GLSL version: {}", glGetString(GL_VERSION));
|
|
|
|
* Reduced code bloat. According to the new `benchmark results
|
|
<https://github.com/fmtlib/fmt#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/>`_:

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/fmtlib/fmt/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 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
|
|

|

CapitalizedWords.

|
Issue `#50 <https://github.com/fmtlib/fmt/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.
