• Have you built your formula locally with HOMEBREW_NO_INSTALL_FROM_API=1 brew install --build-from-source <formula>, where <formula> is the name of the formula you're submitting?
• Is your test running fine brew test <formula>, where <formula> is the name of the formula you're submitting?
• Does your build pass brew audit --strict <formula> (after doing HOMEBREW_NO_INSTALL_FROM_API=1 brew install --build-from-source <formula>)? If this is a new formula, does it pass brew audit --new <formula>?

This is a replacement for #191869 and #192460. This doesn't add a mamba symlink to micromamba, since micromamba and mamba do not have the same interface.

  CMake Error at cmake/Checks.cmake:9 (message):
    Expected type "STATIC_LIBRARY" for target "yaml-cpp::yaml-cpp" but found
    "SHARED_LIBRARY"

I noticed that the yaml-cpp is build with the shared option.

homebrew-core/Formula/y/yaml-cpp.rb

Lines 23 to 26 in 5406dc1

	def install
	system "cmake", ".", *std_cmake_args, "-DYAML_BUILD_SHARED_LIBS=ON",
	"-DYAML_CPP_BUILD_TESTS=OFF"
	system "make", "install"

Digging more history about why it is build with shared option.

Maybe no reason :)

From the yaml-cpp documentation,

yaml-cpp builds a static library by default, you may want to build a shared library by specifying -DYAML_BUILD_SHARED_LIBS=ON. ...

so we may require to build and use the static one.

[carlocab]

We ship the shared libraries according to Homebrew policy: https://docs.brew.sh/Acceptable-Formulae#shared-vs-static-libraries

Formulae should link to shared libraries. There are some intransigent build systems that refuse to do so, but we should fix those wherever we can.

This requires C++17, and it looks like macOS 13 & linux are having issues. Is there something that needs to be done for full C++17 support?

macOS 13:

Why is it skipping the testing part?

I've applied mamba-org/mamba#3613. Though I'm having an issue testing this locally, it's quickly quitting and not telling me why.

[SMillerDev]

Why is it skipping the testing part?

Because of the syntax/style error.

[henryiii]

Ahh, missed that, that was it, thanks!

Thanks @henryiii!
