Add dragonbox to compute the required precision to print floating point
numbers. This avoids uglification of floating point numbers that
happen by default via std::stringstream.

Numbers like 34.34 used to be converted to '34.340000000000003' as strings.
With this version they will be converted to the string '34.34'.

They were commented out before 0733aeb4, but when that commit
was reverted in 2b65c65e they were recovered uncommented.

GCC 15 will no longer include it by default, resulting in build
failures in projects that do not explicitly include it.

Error:

Tests pass.

jekyll/liquid got hung up on `{{"Daniel", 26}, {"Jesse", 24}}`.

The reason is that `{{...}}` are used as variables that are replaced by
there values. In this case we have a YAML object that looks the same.
This issue can be fixed by surrounding the block into `{% raw %}...{%
endraw %}` tags.

This reverts commit 1f5e971f.

See #1306; the previous commit caused an error with -Wpedantic:

yaml-cpp/include/yaml-cpp/emitterstyle.h:13:2: error: extra ‘;’ [-Wpedantic]

Since the original commit was to resolve warnings, reverting and the OP can produce a new one that fixes this issue.

The CMake format target does not use the correct .clang-format file in
out-of-source builds. This instructs CMake to use the project root as
the working directory for running the clang-format command so that it
finds the .clang-format file.

Since `std::string` has to be dynamically constructed and destructed,
it could be accessed before initialization or after destruction in a
multithreaded context. By using constant c-strings instead, we guarantee
that the array will be valid for the whole lifetime of the program. The
use of `constexpr` also enforces this requirement.

I have run clang-format on the file to format my changes according to
CONTRIBUTING.md.

These caused issues when used in a wasm project.

Protect from regressions due to use of undefined or
implementation-specific behavior when using `std::` containers and smart
pointers.

This only has effect on platforms with the GNU standard C++ library.

There is no need to use the embedded gtest code copy in Linux systems, if they already provide the googletest framework system-wide.
Search for it, and fallback to the embedded one if the system one is not detected.
