c++ - 函数参数继续

Question

我正在查看Clang-Format Style Options，但找不到以下选项。如果函数及其自变量破坏了ColumnLimit，我想在新行上继续自变量。

// Good
SomeLongFunction(first_argument,
                 second_argument,
                 third_argument,
                 fourth_argument,
                 fifth_argument);

// Bad
SomeLongFunction(first_argument, second_argument, third_argument,
                 fourth_argument, fifth_argument);

看来 AlignAfterOpenBracket至少会让我配置决定继续下一行时缩进的位置，但是我找不到让我指定的东西来分解参数。

您可能想要:

BinPackParameters: false

这样，您的不良示例将被格式化为良好示例。文档:

BinPackParameters (bool)

If false, a function declaration’s or function definition’s parameters will either all be on the same line or will have one line each.

true:
void f(int aaaaaaaaaaaaaaaaaaaa, int aaaaaaaaaaaaaaaaaaaa,
       int aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa) {}

false:
void f(int aaaaaaaaaaaaaaaaaaaa,
       int aaaaaaaaaaaaaaaaaaaa,
       int aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa) {}

另外:

AllowAllParametersOfDeclarationOnNextLine: false

如果您希望中断所有参数，即使它们在单次中断后适合放在单行中，也可能很有用。说明文件:

AllowAllParametersOfDeclarationOnNextLine (bool)

If the function declaration doesn’t fit on a line, allow putting all parameters of a function declaration onto the next line even if BinPackParameters is false.

true:
void myFunction(
    int a, int b, int c, int d, int e);

false:
void myFunction(int a,
                int b,
                int c,
                int d,
                int e);
