c++ Clang格式:在索引前防止中断

我有一个格式问题与以下(代码编辑的宏是大写,增加了一个混合的情况下版本以及)-

for (i = 0; i < 3; ++i)
{
    MACRO_ARRAY_CALL(param)[i] = MACRO_ARRAY_CALL(param2)[i];
    Macro_array_call(param)[i] = Macro_array_call(param2)[i];
}

其中macro_array_call访问属于param的长度为3的数组(这是一个struct对象)。出于某种原因,我的clang格式文件将此重新格式化为

for (i = 0; i < 3; ++i)
{
    MACRO_ARRAY_CALL(param)
    [i] = MACRO_ARRAY_CALL(param2)[i];
    Macro_array_call(param)[i] = Macro_array_call(param2)[i];
}

我没有看到任何在clang格式,表明一个休息会发生之前,这样的事情。有趣的是,只有当宏观经济完全资本化时才会发生这种情况。到目前为止,我还没有在其他地方看到类似的行为。如果同一个宏是小写和大写的组合,或者只有小写,则不会发生这种情况。
这是我的clang格式文件。我是否需要修改某些内容以获得正确的行为?

找到一些有用的东西。这里的问题似乎是,一个完全资本化的宏观被分解成多行,没有明显的原因。
将其添加为TypenameMacro(可从clangformat9获得),问题就不再出现。

mnemlml8

mnemlml82#

经过几次实验,我找到了一个解决方案:

WhitespaceSensitiveMacros:
  - MACRO_ARRAY_CALL

我不确定它是否修复了已经格式化的代码,但它至少不会破坏手动格式化。如果我找到更好的解决方案,我会更新我的答案。
