Python get#U包含不'；找不到标准库标题

我正在玩弄libclang的Python绑定。目前，我正在尝试执行一些非常简单的任务，例如找到C++文件中包含的所有头。我使用的代码如下：

from clang.cindex import Index

index = Index.create()
tu = index.parse("hello.cpp", args=["-std=c++14"])
for it in tu.get_includes():
    print(it.include.name)

#include <iostream>
#include <stdio.h>
#include "hello.h"

int main()
{
    std::cout << "Hello world\n";
}

#include <list>

文件

hello.cpp

如下所示：

from clang.cindex import Index

index = Index.create()
tu = index.parse("hello.cpp", args=["-std=c++14"])
for it in tu.get_includes():
    print(it.include.name)

#include <iostream>
#include <stdio.h>
#include "hello.h"

int main()
{
    std::cout << "Hello world\n";
}

#include <list>

我认为上面的代码将打印

iostream

，

stdio.h

和

hello.h

，如果考虑到可传递的包含，可能会打印

list

，甚至更多。但是，它只打印

/hello.h

，公然忽略标准库标题

我在文档中找不到任何关于它是否是设计的。这是设计的吗？如果是这样，是否有任何方法可以实际获取带有

clang.cindex

的文件包含的所有标题，包括标准库标题？

也许这会有所帮助：@SimonKraemer不幸的是，这不是真的。我在提出问题之前就发现了，但这只会增加混乱。另外，它似乎使用了一个旧版本的libclang，并且使用了一个微妙不同的API:/you尝试过将过滤器设置为include目录吗？对不起，我不熟悉这些工具。答案看起来好像OP想要的正是你想要的。@SimonKraemer过滤器是OP添加的。通过阅读libclang的代码和文档，似乎没有内置的过滤机制。
