通过clang格式对几乎精确的结构进行不同的格式化

Question

我想使用clang-format自动格式化我的源代码，但是我无法理解类似结构的行为。请参见以下C ++代码：

static someStructLongName structInstanceLong{
    Method1LongLong,       
    structInstanceMethod1, 
    structInstanceMethod1,
    structInstanceMethod3,
    structInstanceMethod4,
    structInstanceMethod5,
    structInstanceMethod6,
    structInstanceMethod7,
    structInstanceMethod8
};

static someStructLongName structInstanceLong{
    Method1,
    structInstanceMethod1,
    structInstanceMethod1,
    structInstanceMethod3,
    structInstanceMethod4,
    structInstanceMethod5,
    structInstanceMethod6,
    structInstanceMethod7,
    structInstanceMethod8
};

当我使用自定义配置文件（附在文章底部）以clang格式对其进行格式化时，得到以下输出：

static someStructLongName structInstanceLong{Method1LongLing,       structInstanceMethod1, structInstanceMethod1,
                                             structInstanceMethod3, structInstanceMethod4, structInstanceMethod5,
                                             structInstanceMethod6, structInstanceMethod7, structInstanceMethod8};

static someStructLongName structInstanceLong{Method1,
                                             structInstanceMethod1,
                                             structInstanceMethod1,
                                             structInstanceMethod3,
                                             structInstanceMethod4,
                                             structInstanceMethod5,
                                             structInstanceMethod6,
                                             structInstanceMethod7,
                                             structInstanceMethod8};

首选第二个选项，但我不知道哪个规则负责此行为，因此要更改什么以强制所有结构使用此结果。

有趣的事情-当我使用此在线工具时： https://zed0.co.uk/clang-format-configurator/ 加载我的配置和上面的代码，一切看起来都像预期的那样。

下面是clang格式的自定义配置：

我使用了一个名为clang-format configurator的工具，它将像第二个选项一样格式化您的代码

BasedOnStyle：铬

AlignEscapedNewlinesLeft：'true'

AlignTrailingComments：'true'

AllowAllParametersOfDeclarationOnNextLine：'false'

AllowShortBlocksOnASingleLine：'true'

AllowShortFunctionsOnASingleLine：全部

BreakBeforeBinaryOperators：'true'

ConstructorInitializerAllOnOneLineOrOnePerLine：'true'

IndentWidth：'1'

IndentWrappedFunctionNames：'true'

KeepEmptyLinesAtTheStartOfBlocks：'false'

SpaceBeforeAssignmentOperators：'false'
