c++ - SpaceBeforeCpp11BracedList 选项在 macOS 中通过 Homebrew 安装的 clang 格式中不可用吗？

Question

我使用 SpaceBeforeCpp11BracedList 选项运行 clang-format 但似乎 clang-format 不知道该选项。以下是错误消息。

YAML:98:29: error: unknown key 'SpaceBeforeCpp11BracedList'
SpaceBeforeCpp11BracedList: true
                            ^~~~
Error reading /Path/to/.clang-format: Invalid argument

它是否发生在通过 homebrew 安装的 clang-format 中？我错过了什么吗？

Answer 1

SpaceBeforeCpp11BracedList 是一个相当新的选项，仅在最近的提交(2018 年 6 月 14 日)中引入，因此在 clang-format 的正式版本中尚不可用:

AFAIK 没有针对 OsX 的夜间 LLVM 构建，因此如果您必须有该选项，则需要从源代码构建主干 LLVM/Clang。
