5.2.0 - TBD
2018-08-11 14:22:41 +00:00
-----------
2018-08-11 14:12:52 +00:00
2018-09-13 00:34:16 +00:00
* Optimized format string parsing and argument processing which resulted in up
to 5x speed up on long format strings and significant performance boost on
various benchmarks. For example, version 5.2 is 2.2x faster than 5.1 on
decimal integer formatting with ``format_to`` (macOS, clang-902.0.39.2):
================== ======= =======
Method Time, s Speedup
================== ======= =======
fmt::format 5.1 0.58
fmt::format 5.2 0.35 1.66
fmt::format_to 5.1 0.51
fmt::format_to 5.2 0.23 2.22
sprintf 0.71
================== ======= =======
2018-09-12 17:39:08 +00:00
* Changed the ``fmt`` macro from opt-out to opt-in to prevent name collisions.
To enable it define the ``FMT_STRING_ALIAS`` macro to 1 before including
``fmt/format.h``:
.. code:: c++
#define FMT_STRING_ALIAS 1
#include <fmt/format.h>
std::string answer = format(fmt("{}"), 42);
2018-09-12 17:39:08 +00:00
* Added compile-time format string checks to ``format_to`` overload that takes
``fmt::memory_buffer`` (`#783 <https://github.com/fmtlib/fmt/issues/783>`_):
2018-09-12 17:39:08 +00:00
.. code:: c++
fmt::memory_buffer buf;
// Compile-time error: invalid type specifier.
fmt::format_to(buf, fmt("{:d}"), "foo");
* Moved experimental color support to ``fmt/color.h`` and enabled the
new API by default. The old API can be enabled by defining the
``FMT_DEPRECATED_COLORS`` macro.
2018-09-12 17:39:08 +00:00
* Added formatting support for types explicitly convertible to
``fmt::string_view``:
.. code:: c++
struct foo {
explicit operator fmt::string_view() const { return "foo"; }
};
auto s = format("{}", foo());
In particular, this makes formatting function work with
``folly::StringPiece``.
* Implemented preliminary support for ``char*_t`` by replacing the ``format``
function overloads with a single function template parameterized on the string
type.
2018-08-11 14:12:52 +00:00
* Added support for dynamic argument lists
(`#814 <https://github.com/fmtlib/fmt/issues/814>`_,
2018-09-12 17:39:08 +00:00
`#819 <https://github.com/fmtlib/fmt/pull/819>`_).
2018-08-11 14:12:52 +00:00
Thanks `@MikePopoloski (Michael Popoloski)
<https://github.com/MikePopoloski>`_.
* Reduced executable size overhead for embedded targets using newlib nano by
making locale dependency optional
(`#839 <https://github.com/fmtlib/fmt/pull/839>`_).
Thanks `@teajay-fr (Thomas Benard) <https://github.com/teajay-fr>`_.
2018-09-12 17:39:08 +00:00
* Keep ``noexcept`` specifier when exceptions are disabled
(`#801 <https://github.com/fmtlib/fmt/issues/801>`_,
`#810 <https://github.com/fmtlib/fmt/pull/810>`_).
Thanks `@qis (Alexej Harm) <https://github.com/qis>`_.
* Fixed formatting of user-defined types providing ``operator<<`` with
``format_to_n``
(`#806 <https://github.com/fmtlib/fmt/pull/806>`_).
Thanks `@mkurdej (Marek Kurdej) <https://github.com/mkurdej>`_.
* Fixed dynamic linkage of new symbols
(`#808 <https://github.com/fmtlib/fmt/issues/808>`_).
* Fixed global initialization issue
(`#807 <https://github.com/fmtlib/fmt/issues/807>`_):
.. code:: c++
// This works on compilers with constexpr support.
static const std::string answer = fmt::format("{}", 42);
* Fixed various compiler warnings and errors
(`#804 <https://github.com/fmtlib/fmt/pull/804>`_,
`#809 <https://github.com/fmtlib/fmt/issues/809>`_,
`#811 <https://github.com/fmtlib/fmt/pull/811>`_,
`#822 <https://github.com/fmtlib/fmt/issues/822>`_,

`#852 <https://github.com/fmtlib/fmt/pull/852>`_,
`#854 <https://github.com/fmtlib/fmt/pull/854>`_).
Thanks `@henryiii (Henry Schreiner) <https://github.com/henryiii>`_,
`@medithe <https://github.com/medithe>`_, and
`@eliasdaler (Elias Daler) <https://github.com/eliasdaler>`_.

5.1.0 - 2018-07-05
------------------
2018-07-04 23:00:06 +00:00
* Added experimental support for RGB color output enabled with
the ``FMT_EXTENDED_COLORS`` macro:
.. code:: c++
#define FMT_EXTENDED_COLORS
#define FMT_HEADER_ONLY // or compile fmt with FMT_EXTENDED_COLORS defined
#include <fmt/format.h>
fmt::print(fmt::color::steel_blue, "Some beautiful text");
The old API (the ``print_colored`` and ``vprint_colored`` functions and the
``color`` enum) is now deprecated.
(`#762 <https://github.com/fmtlib/fmt/issues/762>`_
`#767 <https://github.com/fmtlib/fmt/pull/767>`_).
2018-08-11 14:12:52 +00:00
thanks `@remotion (remo) <https://github.com/remotion>`_.
2018-07-04 23:00:06 +00:00
* Added quotes to strings in ranges and tuples
(`#766 <https://github.com/fmtlib/fmt/pull/766>`_).
Thanks `@Remotion (Remo) <https://github.com/Remotion>`_.
* Made ``format_to`` work with ``basic_memory_buffer``
(`#776 <https://github.com/fmtlib/fmt/issues/776>`_).
* Added ``vformat_to_n`` and ``wchar_t`` overload of ``format_to_n``
(`#764 <https://github.com/fmtlib/fmt/issues/764>`_,
`#769 <https://github.com/fmtlib/fmt/issues/769>`_).
* Made ``is_range`` and ``is_tuple_like`` part of public (experimental) API
to allow specialization for user-defined types
(`#751 <https://github.com/fmtlib/fmt/issues/751>`_,
`#759 <https://github.com/fmtlib/fmt/pull/759>`_).
Thanks `@drrlvn (Dror Levin) <https://github.com/drrlvn>`_.
* Added more compilers to continuous integration and increased ``FMT_PEDANTIC``
warning levels
(`#736 <https://github.com/fmtlib/fmt/pull/736>`_).
Thanks `@eliaskosunen (Elias Kosunen) <https://github.com/eliaskosunen>`_.
* Fixed compilation with MSVC 2013.
* Fixed handling of user-defined types in ``format_to``
(`#793 <https://github.com/fmtlib/fmt/issues/793>`_).
* Forced linking of inline ``vformat`` functions into the library
(`#795 <https://github.com/fmtlib/fmt/issues/795>`_).
* Fixed incorrect call to on_align in ``'{:}='``
(`#750 <https://github.com/fmtlib/fmt/issues/750>`_).
* Fixed floating-point formatting to a non-back_insert_iterator with sign &
numeric alignment specified
(`#756 <https://github.com/fmtlib/fmt/issues/756>`_).
* Fixed formatting to an array with ``format_to_n``
(`#778 <https://github.com/fmtlib/fmt/issues/778>`_).
* Fixed formatting of more than 15 named arguments
(`#754 <https://github.com/fmtlib/fmt/issues/754>`_).
* Fixed handling of compile-time strings when including ``fmt/ostream.h``.
(`#768 <https://github.com/fmtlib/fmt/issues/768>`_).

2018-07-04 23:00:06 +00:00
2018-05-22 04:00:04 +00:00
5.0.0 - 2018-05-21
------------------
2018-05-12 16:10:11 +00:00
2018-05-13 19:42:55 +00:00
* Added a requirement for partial C++11 support, most importantly variadic
templates and type traits, and dropped ``FMT_VARIADIC_*`` emulation macros.
Variadic templates are available since GCC 4.4, Clang 2.9 and MSVC 18.0 (2013).
For older compilers use {fmt} `version 4.x
2018-05-13 15:53:16 +00:00
<https://github.com/fmtlib/fmt/releases/tag/4.1.0>`_ which continues to be
2018-05-13 19:42:55 +00:00
maintained and works with C++98 compilers.
2018-05-12 16:10:11 +00:00
2018-05-13 15:53:16 +00:00
* Renamed symbols to follow standard C++ naming conventions and proposed a subset
of the library for standardization in `P0645R2 Text Formatting
<https://wg21.link/P0645>`_.
2018-05-12 16:10:11 +00:00
2018-05-19 17:31:49 +00:00
* Implemented ``constexpr`` parsing of format strings and `compile-time format
string checks
<http://fmtlib.net/dev/api.html#compile-time-format-string-checks>`_. For
example
.. code:: c++
#include <fmt/format.h>
2018-05-20 23:00:39 +00:00
2018-05-19 17:31:49 +00:00
std::string s = format(fmt("{:d}"), "foo");
2018-05-19 18:46:55 +00:00
gives a compile-time error because ``d`` is an invalid specifier for strings
2018-05-22 03:38:07 +00:00
(`godbolt <https://godbolt.org/g/rnCy9Q>`__)::
2018-05-19 17:31:49 +00:00
...
<source>:4:19: note: in instantiation of function template specialization 'fmt::v5::format<S, char [4]>' requested here
std::string s = format(fmt("{:d}"), "foo");
^
format.h:1337:13: note: non-constexpr function 'on_error' cannot be used in a constant expression
handler.on_error("invalid type specifier");
2018-05-13 19:42:55 +00:00
2018-05-19 18:46:55 +00:00
Compile-time checks require relaxed ``constexpr`` (C++14 feature) support. If
the latter is not available, checks will be performed at runtime.
2018-05-13 19:42:55 +00:00
* Separated format string parsing and formatting in the extension API to enable
compile-time format string processing. For example
2018-05-13 15:53:16 +00:00
.. code:: c++
2018-05-22 03:27:58 +00:00
struct Answer {};
2018-05-13 15:53:16 +00:00
namespace fmt {
template <>
2018-05-22 03:27:58 +00:00
struct formatter<Answer> {
2018-05-13 15:53:16 +00:00
constexpr auto parse(parse_context& ctx) {
auto it = ctx.begin();
spec = *it;
if (spec != 'd' && spec != 's')
throw format_error("invalid specifier");
2018-05-13 19:42:55 +00:00
return ++it;
2018-05-13 15:53:16 +00:00
}
template <typename FormatContext>
2018-05-22 03:27:58 +00:00
auto format(Answer, FormatContext& ctx) {
2018-05-13 15:53:16 +00:00
return spec == 's' ?
format_to(ctx.begin(), "{}", "fourty-two") :
format_to(ctx.begin(), "{}", 42);
}
char spec = 0;
};
}
2018-05-22 03:27:58 +00:00
std::string s = format(fmt("{:x}"), Answer());
2018-05-13 15:53:16 +00:00
2018-05-19 17:31:49 +00:00
gives a compile-time error due to invalid format specifier (`godbolt
2018-05-22 03:38:07 +00:00
<https://godbolt.org/g/2jQ1Dv>`__)::
2018-05-13 15:53:16 +00:00
...
<source>:12:45: error: expression '<throw-expression>' is not a constant expression
throw format_error("invalid specifier");
2018-05-16 14:58:43 +00:00
* Added `iterator support
<http://fmtlib.net/dev/api.html#output-iterator-support>`_:
.. code:: c++
#include <vector>
#include <fmt/format.h>
std::vector<char> out;
fmt::format_to(std::back_inserter(out), "{}", 42);
2018-05-19 18:46:55 +00:00
* Added the `format_to_n
<http://fmtlib.net/dev/api.html#_CPPv2N3fmt11format_to_nE8OutputItNSt6size_tE11string_viewDpRK4Args>`_
function that restricts the output to the specified number of characters
(`#298 <https://github.com/fmtlib/fmt/issues/298>`_):
.. code:: c++
char out[4];
fmt::format_to_n(out, sizeof(out), "{}", 12345);
// out == "1234" (without terminating '\0')
2018-05-16 15:19:26 +00:00
* Added the `formatted_size
2018-05-19 14:13:06 +00:00
<http://fmtlib.net/dev/api.html#_CPPv2N3fmt14formatted_sizeE11string_viewDpRK4Args>`_
function for computing the output size:
2018-05-16 15:19:26 +00:00
.. code:: c++
#include <fmt/format.h>
auto size = fmt::formatted_size("{}", 12345); // size == 5
2018-05-13 19:42:55 +00:00
* Improved compile times by reducing dependencies on standard headers and
providing a lightweight `core API <http://fmtlib.net/dev/api.html#core-api>`_:
.. code:: c++
#include <fmt/core.h>
fmt::print("The answer is {}.", 42);
See `Compile time and code bloat
<https://github.com/fmtlib/fmt#compile-time-and-code-bloat>`_.
2018-05-13 15:53:16 +00:00
* Added the `make_format_args
<http://fmtlib.net/dev/api.html#_CPPv2N3fmt16make_format_argsEDpRK4Args>`_
function for capturing formatting arguments:
2018-05-12 16:10:11 +00:00
.. code:: c++
// Prints formatted error message.
void vreport_error(const char *format, fmt::format_args args) {
fmt::print("Error: ");
fmt::vprint(format, args);
}
template <typename... Args>
void report_error(const char *format, const Args & ... args) {
vreport_error(format, fmt::make_format_args(args...));
}
2018-07-04 23:00:06 +00:00
* Added the ``make_printf_args`` function for capturing ``printf`` arguments
(`#687 <https://github.com/fmtlib/fmt/issues/687>`_,
2018-05-20 23:00:39 +00:00
`#694 <https://github.com/fmtlib/fmt/pull/694>`_).
2018-05-19 18:46:55 +00:00
Thanks `@Kronuz (Germán Méndez Bravo) <https://github.com/Kronuz>`_.
2018-05-13 15:53:16 +00:00
* Added prefix ``v`` to non-variadic functions taking ``format_args`` to
distinguish them from variadic ones:
2018-05-12 16:10:11 +00:00
.. code:: c++
std::string vformat(string_view format_str, format_args args);
template <typename... Args>
2018-05-12 16:42:59 +00:00
std::string format(string_view format_str, const Args & ... args);
2018-05-20 23:00:39 +00:00
* Added experimental support for formatting ranges, containers and tuple-like
types in ``fmt/ranges.h`` (`#735 <https://github.com/fmtlib/fmt/pull/735>`_):
.. code:: c++
#include <fmt/ranges.h>
std::vector<int> v = {1, 2, 3};
fmt::print("{}", v); // prints {1, 2, 3}
Thanks `@Remotion (Remo) <https://github.com/Remotion>`_.
* Implemented ``wchar_t`` date and time formatting
(`#712 <https://github.com/fmtlib/fmt/pull/712>`_):
.. code:: c++
#include <fmt/time.h>
std::time_t t = std::time(nullptr);
auto s = fmt::format(L"The date is {:%Y-%m-%d}.", *std::localtime(&t));
Thanks `@DanielaE (Daniela Engert) <https://github.com/DanielaE>`_.
* Provided more wide string overloads
(`#724 <https://github.com/fmtlib/fmt/pull/724>`_).
Thanks `@DanielaE (Daniela Engert) <https://github.com/DanielaE>`_.
2018-05-13 15:53:16 +00:00
* Switched from a custom null-terminated string view class to ``string_view``
in the format API and provided ``fmt::string_view`` which implements a subset
of ``std::string_view`` API for pre-C++17 systems.
2018-05-16 14:58:43 +00:00
* Added support for ``std::experimental::string_view``
(`#607 <https://github.com/fmtlib/fmt/pull/607>`_):
.. code:: c++
#include <fmt/core.h>
#include <experimental/string_view>
fmt::print("{}", std::experimental::string_view("foo"));
Thanks `@virgiliofornazin (Virgilio Alexandre Fornazin)
2018-05-22 03:38:07 +00:00
<https://github.com/virgiliofornazin>`__.
2018-05-16 14:58:43 +00:00
2018-05-13 19:42:55 +00:00
* Allowed mixing named and automatic arguments:
.. code:: c++
fmt::format("{} {two}", 1, fmt::arg("two", 2));
2018-05-13 15:53:16 +00:00
* Removed the write API in favor of the `format API
<http://fmtlib.net/dev/api.html#format-api>`_ with compile-time handling of
format strings.
2018-05-12 16:42:59 +00:00
2018-05-13 19:42:55 +00:00
* Disallowed formatting of multibyte strings into a wide character target
(`#606 <https://github.com/fmtlib/fmt/pull/606>`_).
2018-07-04 23:00:06 +00:00
* Improved documentation
(`#515 <https://github.com/fmtlib/fmt/pull/515>`_,

2018-05-12 16:42:59 +00:00
Thanks `@chronoxor (Ivan Shynkarenka) <https://github.com/chronoxor>`_.
2018-05-19 18:46:55 +00:00
* Moved ``fmt/*.h`` to ``include/fmt/*.h`` to prevent irrelevant files and
directories appearing on the include search paths when fmt is used as a
subproject and moved source files to the ``src`` directory.
2018-05-19 14:13:06 +00:00
* Added qmake project file ``support/fmt.pro``
(`#641 <https://github.com/fmtlib/fmt/pull/641>`_).
Thanks `@cowo78 (Giuseppe Corbelli) <https://github.com/cowo78>`_.

2018-01-21 01:39:15 +00:00
2018-05-13 19:42:55 +00:00
* Fixed a name conflict with the macro ``CHAR_WIDTH`` in glibc
(`#616 <https://github.com/fmtlib/fmt/pull/616>`_).
Thanks `@aroig (Abdó Roig-Maranges) <https://github.com/aroig>`_.

------------------
2016-05-04 15:49:29 +00:00
* The project has been renamed from C++ Format (cppformat) to fmt for
consistency with the used namespace and macro prefix

.. code:: c++
#include "fmt/format.h"

2016-05-07 15:59:19 +00:00
The documentation is now available at http://fmtlib.net.

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
2016-04-28 13:45:50 +00:00
(`#79 <https://github.com/fmtlib/fmt/issues/79>`_).
2015-03-05 16:04:27 +00:00
This eliminates size computation for string literals on reasonable optimizing
compilers.
* Fix formatting of types with overloaded ``operator <<`` for ``std::wostream``
2016-04-28 13:45:50 +00:00
(`#86 <https://github.com/fmtlib/fmt/issues/86>`_):
2015-03-05 16:04:27 +00:00
.. code:: c++
fmt::format(L"The date is {0}", Date(2012, 12, 9));
* Fix linkage of tests on Arch Linux
2016-04-28 13:45:50 +00:00
(`#89 <https://github.com/fmtlib/fmt/issues/89>`_).
2015-03-05 16:04:27 +00:00
* Allow precision specifier for non-float arguments
2016-04-28 13:45:50 +00:00
(`#90 <https://github.com/fmtlib/fmt/issues/90>`_):
2015-03-05 16:04:27 +00:00
.. code:: c++
fmt::print("{:.3}\n", "Carpet"); // prints "Car"
* Fix build on Android NDK
2016-04-28 13:45:50 +00:00
(`#93 <https://github.com/fmtlib/fmt/issues/93>`_)
2015-03-05 16:04:27 +00:00
* 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.
2015-03-05 15:26:44 +00:00
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
2016-04-28 13:45:50 +00:00
(`#69 <https://github.com/fmtlib/fmt/issues/69>`_)
2015-03-05 15:26:44 +00:00
* Formatting functions now accept `signed char` and `unsigned char` strings as
2016-04-28 13:45:50 +00:00
arguments (`#73 <https://github.com/fmtlib/fmt/issues/73>`_):
2015-03-05 15:26:44 +00:00
.. code:: c++
auto s = format("GLSL version: {}", glGetString(GL_VERSION));
* Reduced code bloat. According to the new `benchmark results
2016-04-28 13:45:50 +00:00
<https://github.com/fmtlib/fmt#compile-time-and-code-bloat>`_,
2015-03-05 15:26:44 +00:00
cppformat is close to ``printf`` and by the order of magnitude better than
Boost Format in terms of compiled code size.
2015-03-05 15:31:27 +00:00
* 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);
2015-03-05 03:02:59 +00:00
* Arguments of ``char`` type can now be formatted as integers
2016-04-28 13:45:50 +00:00
(Issue `#55 <https://github.com/fmtlib/fmt/issues/55>`_):
2015-03-05 02:49:23 +00:00
.. 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.
2015-03-05 02:30:00 +00:00
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'
2016-05-01 10:29:21 +00:00
lifetimes. Because the wrapper functions are very lightweight, this doesn't
2015-03-05 02:30:00 +00:00
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
2015-03-05 03:02:59 +00:00
CapitalizedWords.
2016-04-28 13:45:50 +00:00
Issue `#50 <https://github.com/fmtlib/fmt/issues/50>`_.
2015-03-05 02:30:00 +00:00
* 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).
2015-03-05 02:10:08 +00:00
0.9.0 - 2014-05-13
------------------
* More efficient implementation of variadic formatting functions.
2015-03-05 02:16:26 +00:00
* ``Writer::Format`` now has a variadic overload:
.. code:: c++
2015-03-05 02:10:08 +00:00
Writer out;
out.Format("Look, I'm {}!", "variadic");
* For efficiency and consistency with other overloads, variadic overload of
2015-03-05 02:16:26 +00:00
the ``Format`` function now returns ``Writer`` instead of ``std::string``.
Use the ``str`` function to convert it to ``std::string``:
.. code:: c++
2015-03-05 02:10:08 +00:00
std::string s = str(Format("Look, I'm {}!", "variadic"));
2015-03-05 02:16:26 +00:00
* 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
2015-03-05 02:10:08 +00:00
2015-03-05 02:16:26 +00:00
.. code:: c++
2015-03-05 02:10:08 +00:00
FILE *f = fopen(filename, "r");
if (!f)
ThrowSystemError(errno, "Failed to open file '{}'") << filename;
2015-03-05 02:16:26 +00:00
will throw ``SystemError`` exception with description
2015-03-05 02:10:08 +00:00
"Failed to open file '<filename>': No such file or directory" if file
doesn't exist.
2015-03-05 02:49:23 +00:00
* Support for AppVeyor continuous integration platform.
2015-03-05 02:10:08 +00:00
2015-03-05 02:16:26 +00:00
* ``Format`` now throws ``SystemError`` in case of I/O errors.
2015-03-05 02:10:08 +00:00
* Improve test infrastructure. Print functions are now tested by redirecting
the output to a pipe.
0.8.0 - 2014-04-14
