clang-format堆栈所有if语句参数，如果它们太长 [英] clang-format stack all if-statement arguments if they are too long

问题描述

我有一个if语句，该语句具有几个or ed参数.为了便于阅读，我将它们垂直堆叠如下.

I have an if statement that has several ored arguments. I have stacked them vertically as below for readability.

    if (health.flag_a || 
       health.flag_b ||
       health.flag_c ||
       health.flag_d ||
       health.flag_e ||
       health.flag_f ||
       health.flag_g ||
       health.flag_h ||
       health.flag_i ||
       health.flag_k) {
    do_something();
    return false;
}

clang-format将此转换为:

if (health.flag_a || health.flag_b || health.flag_c || health.flag_d || health.flag_e || health.flag_f || health.flag_g || health.flag_h ||
    health.flag_i || health.flag_k) {
    do_something();
    return false;
}

如果它们不能排成一行，我希望clang-format像上面那样堆叠它们. 我期望BinPackArguments做到这一点，但是我没有任何运气.

I want clang-format to stack them like above if they don't fit on one line. I expected BinPackArguments do this, but I'm not having any luck.

这可以实现吗?

请参阅下面的.clang-format.

感谢您的帮助.

推荐答案

不直接，但是您可以使用BreakBeforeBinaryOperators来实现类似目的.尝试将此值设置为NonAssignment.但是，这会将您的||运算符放在每个其他条件之前 ，而不是放在它们之后.

Not directly, but you can achieve something like it with BreakBeforeBinaryOperators. Try setting this value to NonAssignment. This will put your || operators before each additional condition, though, not after them.
