    To activate the syntax highlighting, add the following at the end of your .zshrc:

      source #{HOMEBREW_PREFIX}/share/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh

    You will also need to force reload of your .zshrc:

      source ~/.zshrc

    Additionally, if your receive "highlighters directory not found" error message,
    you may need to add the following to your .zshenv:

      export ZSH_HIGHLIGHT_HIGHLIGHTERS_DIR=#{HOMEBREW_PREFIX}/share/zsh-syntax-highlighting/highlighters
    EOS
  end

  test do
    assert_match "#{version}\n",
      shell_output("zsh -c '. #{share}/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh && echo $ZSH_HIGHLIGHT_VERSION'")
  end
end
