5.2.0 - TBD
-----------
* Optimized format string parsing and argument processing
* Added compile-time format string checks to ``format_to`` overload that takes
``fmt::memory_buffer`` (`#783 <https://github.com/fmtlib/fmt/issue/783>`_):
.. code:: c++
fmt::memory_buffer buf;
// Compile-time error: invalid type specifier.
fmt::format_to(buf, fmt("{:d}"), "foo");
* 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``.
* Added support for dynamic argument lists
(`#766 <https://github.com/fmtlib/fmt/issue/814>`_,
`#766 <https://github.com/fmtlib/fmt/pull/819>`_).
(`#814 <https://github.com/fmtlib/fmt/issue/814>`_,
`#819 <https://github.com/fmtlib/fmt/pull/819>`_).
Thanks `@MikePopoloski (Michael Popoloski)
<https://github.com/MikePopoloski>`_.
* 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>`_).
Thanks `@henryiii (Henry Schreiner) <https://github.com/henryiii>`_.
