  New library with various C++20 concepts.

• fcppt.container

  • Added fcppt::container::uncons.

• fcppt.mpl

  New library that replaces Metal.

  • Added operator-> to fcppt::recursive.

Changed functionality

Removed functionality

• fcppt.assert

  • Removed FCPPT_ASSERT_UNIMPLEMENTED_MESSAGE.
  • Removed FCPPT_ASSERT_PRE and FCPPT_ASSERT_PRE_MESSAGE.

• fcppt.container

  • Removed fcppt::container::contains. In C++20, maps have a contains member function.

• fcppt.endianness

  • Removed fcppt::endianness::format, fcppt::endianness::is_big_endian, fcppt::endianness::is_little_endian and fcppt::endianness::host_format. Use std::endian instead.

• fcppt.math

  • Removed fcppt::math::pi and fcppt::math::twopi. Use std::numbers::pi_v instead.

• fcpptmetal

  This has been removed in favor of fcppt.mpl.

Bugfixes

• fcppt.string

  • Fixed failure condition of fcppt::extract_from_string, fcppt::extract_from_string_fmt and fcppt::extract_from_string_locale_fmt. It was previously possible that every character of the string has been consumed but EOF has not been reached either.
