c++ - 如何使 Clang-Format 在 : operator in class/struct 之前插入换行符

Question

我正在尝试使用 clang-format 3.7 格式化一些代码。

我有一个看起来有点像这样的结构:

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

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

这很好，但是 clang-format 坚持这样格式化它:

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，并且更愿意将大括号放在同一行，但我可以没有它。

这是我当前的 .clang-format 文件，有什么办法可以改变它吗？

Answer 1

你有 BreakConstructorInitializersBeforeComma: false 你想要 true。
