如何在Clang格式前插入换行符:类/结构中的运算符

Question

我正在尝试用clang-format 3.7格式化一些代码。

我有一个结构，看起来有点像这样：

struct NameOfStruct
{
  explicit NameOfStruct()
    : Thing1(-1), Thing2(-1)
  {}

  std::size_t objectA;
  std::size_t objectB;
};

这很好，但是clang-format坚持这样格式化：

struct NameOfStruct
{
  explicit NameOfStruct() : Thing1(-1), Thing2(-1)
  {
  }

  std::size_t objectA;
  std::size_t objectB;
};

我更愿意将Thing1和Thing2放在下一行，也更愿意把大括号放在同一行，但是没有它我也能活下去。

这是我当前的.clang-format文件，有什么方法可以改变它吗？

Answer 1

你可以在你想要true的地方使用BreakConstructorInitializersBeforeComma: false。
