在Cmake中为clang-tidy提供标题过滤器的正确方式是什么？

Question

我有一些项目设置Clang-tidy配置，如下所示

set(CMAKE_CXX_CLANG_TIDY "clang-tidy;-checks=google-*,cppcoreguidelines-*;")

但是，我注意到它正在检查所有甚至不在当前存储库中的文件，比如

/opt/ros/melodic/include/ros/console.h

以及子模块的所有.h/.hpp文件...

我试图添加一个正则表达式来过滤目标.h文件，但无法使其正常工作……我已经给出了单个.hpp文件的绝对路径，但它仍在评估/opt/ros/melodic/include文件……

我可以有一个关于头过滤器的例子吗？？

如果hpp在过滤器中，我假设clang-tidy会检查相应的cpp文件。我说的对吗？

Answer 1

你可以看看这个例子。这是我的承诺。https://github.com/cocos2d/cocos2d-x/pull/19928

这就是我用正则表达式在两个目录上禁用clang-tidy检查的方法。

'^((?!/cocos2d-x/external/|/cocos/scripting/).)*$'

禁用对external目录和cocos/scripting目录的clang-tidy检查。

我创建了一个python脚本来测试正则表达式是否按预期工作。

#!/usr/bin/env python
import re

files = [ 
"/home/john/cocos2d-x/external/openssl/include/linux/openssl/bio.h",
"/home/john/cocos2d-x/external/tiff/include/linux/tiff.h",
"/home/john/git/cocos/cocos2d-x/cocos/scripting/lua-bindings/auto/lua_cocos2dx_3d_auto.cpp"
"/home/john/cocos2d-x/external/json/stringbuffer.h",
"/home/john/cocos2d-x/cocos/base/ccUtils.h",
"/home/john/git/cocos/cocos2d-x/cocos/scripting/js-bindings/precheader.cpp",
"/home/john/cocos2d-x/cocos/physics/CCPhysicsBody.cpp",
"/home/john/cocos2d-x/tests/cpp-tests/Classes/ActionsEaseTest/ActionsEaseTest.cpp",
"/home/john/cocos2d-x/templates/cpp-template-default/Classes/AppDelegate.cpp",
"/home/john/git/cocos/cocos2d-x/cocos/scripting/js-bindings/proj.android/CMakeLists.txt",
]

pattern = '^((?!/cocos2d-x/external/|/cocos/scripting/).)*$'

for file in files:
    m = re.search(pattern, file)
    if m:
        print m.group(0)

运行此python文件，输出为

/home/john/cocos2d-x/cocos/base/ccUtils.h
/home/john/cocos2d-x/cocos/physics/CCPhysicsBody.cpp
/home/john/cocos2d-x/tests/cpp-tests/Classes/ActionsEaseTest/ActionsEaseTest.cpp
/home/john/cocos2d-x/templates/cpp-template-default/Classes/AppDelegate.cpp

您可以修改正则表达式和python测试脚本，以查看它是否工作。
