Clang-Tidy：可读性-功能-认知-complexity.DescribeBasicIncrements 值无效

Question

虽然运行 clang-tidy 在 https://clang.llvm.org/extra/clang-tidy/checks/readability-function-cognitive-complexity.html 提供的示例代码中参考 function3。

使用以下命令

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，好像readability-function-cognitive-complexity.DescribeBasicIncrements这个键没有作用。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}

但仍然在增加认知复杂性的线路上进行了额外的诊断。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 版本 12.0

Answer 1

这是您问题的根源：

Additional info:

clang version 12.0

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。
