@ -6,13 +6,11 @@ API Reference
The {fmt} library API consists of the following parts:
* :ref:`fmt/core.h <core-api>`: the core API providing argument handling
facilities and a lightweight subset of formatting functions
* :ref:`fmt/format.h <format-api>`: the full format API providing compile-time
format string checks, wide string, output iterator and user-defined type
support
* :ref:`fmt/ranges.h <ranges-api>`: additional formatting support for ranges
and tuples
* :ref:`fmt/core.h <core-api>`: the core API providing main formatting functions
for ``char``/UTF-8 with compile-time checks and minimal dependencies
* :ref:`fmt/format.h <format-api>`: the full format API providing additional
formatting functions and locale support
* :ref:`fmt/ranges.h <ranges-api>`: formatting of ranges and tuples
* :ref:`fmt/chrono.h <chrono-api>`: date and time formatting
* :ref:`fmt/compile.h <compile-api>`: format string compilation
* :ref:`fmt/color.h <color-api>`: terminal color and text style

Core API
========
``fmt/core.h`` defines the core API which provides argument handling facilities
and a lightweight subset of formatting functions. It is only beneficial when
using {fmt} as a library and not in the header-only mode.
``fmt/core.h`` defines the core API which provides main formatting functions for
``char``/UTF-8 with compile-time checks. It has minimal include dependencies for
better compile times. This header is only beneficial when using {fmt} as a

Compile-time Format String Checks
---------------------------------
Compile-time checks are enabled when using ``FMT_STRING``. They support built-in
and string types as well as user-defined types with ``constexpr`` ``parse``
functions in their ``formatter`` specializations.
.. doxygendefine:: FMT_STRING
To force the use of compile-time checks, define the preprocessor variable
``FMT_ENFORCE_COMPILE_STRING``. When set, functions accepting ``FMT_STRING``
will fail to compile with regular strings. Runtime-checked
formatting is still possible using ``fmt::vformat``, ``fmt::vprint``, etc.
