Clang-Tidy : readability-function-cognitive-complexity.DescribeBasicIncrements 值没有影响

如何解决Clang-Tidy : readability-function-cognitive-complexity.DescribeBasicIncrements 值没有影响

在 https://clang.llvm.org/extra/clang-tidy/checks/readability-function-cognitive-complexity.html 提供的示例代码上运行 clang-tidy 时，请参阅函数 3。

使用下面的命令

clang-tidy.exe Example.cpp -config="{Checks: '-*,readability-*',CheckOptions: [{key: readability-function-cognitive-complexity.Threshold,value: 2},{key: readability-function-cognitive-complexity.DescribeBasicIncrements,value: false} ]}"

我得到低于输出。

\Example.cpp:2:5: warning: function 'function3' has cognitive complexity of 3 (threshold 2) [readability-function-cognitive-complexity]
int function3(bool var1,bool var2) {
    ^
\Example.cpp:3:3: note: +1,including nesting penalty of 0,nesting level increased to 1
  if(var1) { // +1,nesting level +1
  ^
\Example.cpp:4:5: note: +2,including nesting penalty of 1,nesting level increased to 2
    if(var2)  // +2 (1 + current nesting level of 1),nesting level +1
    ^
\Example.cpp:4:13: warning: statement should be inside braces [readability-braces-around-statements]
    if(var2)  // +2 (1 + current nesting level of 1),nesting level +1
            ^
             {
\Example.cpp:5:14: warning: 42 is a magic number; consider replacing it with a named constant [readability-magic-numbers]
      return 42;

所以，键 readability-function-cognitive-complexity.DescribeBasicIncrements 似乎没有任何作用。我也试过

{key: readability-function-cognitive-complexity.DescribeBasicIncrements,value: 'false'}`
{key: readability-function-cognitive-complexity.DescribeBasicIncrements,value: '0'}
{key: readability-function-cognitive-complexity.DescribeBasicIncrements,value: 0} 

但仍然获得了增加认知复杂性的额外诊断。 所以，我认为 readability-function-cognitive-complexity.DescribeBasicIncrements 坏了还是我做错了什么？

附加信息：

• clang 12.0 版

解决方法

这是您问题的根源：

附加信息：

• clang 12.0 版

DescribeBasicIncrements 选项是在 this commit 中引入的，它不是 clang 12.0 的一部分

安装最新的 clang 版本，它应该可以正常工作。
