    Metadata details:

    path of file: ./repos/homebrew-core/Formula/s
    
    the code of the file until where you have to start completion: class Sdl2Ttf 
    
  def install
    inreplace "SDL2_ttf.pc.in", "@prefix@", HOMEBREW_PREFIX

    system "./autogen.sh" if build.head?

    # `--enable-harfbuzz` is the default, but we pass it
    # explicitly to generate an error when it isn't found.
    system "./configure", "--disable-freetype-builtin",
                          "--disable-harfbuzz-builtin",
                          "--enable-harfbuzz",
                          *std_configure_args
    system "make", "install"
