Clang-tidy 是一个比较实用的代码检查程序，它可以检测出很多笔误等低级错误，也会提出一些已经得到广泛验证的 best practice，不过提供的检查数量众多，有些过于严苛，还有一些互相矛盾（比如 fuchsia-trailing-return 建议你永远不要写 尾随返回类型，但 modernize-use-trailing-return-type 建议你总是这样写），所以我们必须有选择地打开一部分真正有必要的检查。 我过了一遍目前（2022-01-19）提供的 所有检查项目，然后根据 CLion 默认设置的建议，以及很少量的个人经验，列出了比较推荐打开的检查（可以直接粘贴到 CLion 设置中），我筛选的原则是： 平台相关的（比如安卓）检查项目不列入；特定第三方库相关的检查项目不列入；矛盾的两个项目，都不列入；与某些 无害的 编程习惯有关，且对可读性影响也不大的，由于因人而异，不列入（比如：应该写 if {... return;} else {... return;} 还是 if {... return;} ... return;？）；少数会引起警告，但太过普遍的做法，不列入（比如：将数组名退化为首地址指针作实参，会引起警告；字符数组退化为字符常量指针也不例外）；如果一个检查项目会干扰 常见的、故意设计的行为，且这样写的后果能够在字面上立即预测出时，不列入该项目（比如：某个检查会在随机数发生器使用确定数字作为种子时发出警告，提示“这会产生可预期的随机序列”，而这显然正是我们的意图）；除以上情况之外，都列入。 -* bugprone-assert-side-effect bugprone-bad-signal-to-kill-thread

原生提供的检查重合了，不需要打开的项目（其它 IDE 如果没提供类似的检查，则建议打开）： bugprone-argument-comment 参考链接：CLion 本身具有函数调用时的参数名内联提示，除非你们的代码规范要求给每个函数调用写参数注解，否则这个可能没必要；bugprone-infinite-loop 参考链接：CLion 本身具有无限循环检查，功能重复；misc-unused-parameters 参考链接：CLion 本身具有未使用参数检查。 |
