C++ Format v0.12.0 Release Notes

Release Date: 2014-10-25 // over 9 years ago
    • [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/>_:
