Question

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

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

在通过clang-format安装的homebrew中发生了吗？我错过了什么吗？

下面是我的.clang-format文件

Answer 1

SpaceBeforeCpp11BracedList是一个相当新的选项，仅在最近的一次提交（2018年6月14日）中引入，因此在正式版的clang格式中尚未提供：

https://reviews.llvm.org/D46024

OsX和AFAIK不需要每晚进行LLVM构建，因此，如果必须选择该选项，则需要从源代码构建主干LLVM / Clang。

通过Mac OS中的Homebrew安装的clang格式的SpaceBeforeCpp11BracedList选项是否不可用？
