Windows上安装libclang的方法
在官网https://llvm.org/下载LLVM Win Installer。安装完成后,在安装目录下找libclang.dll。
Mac上安装libclang的python绑定的方法
pip install clang
Mac上libclang的位置
With the latest (appstore) XCode 4.3.2, the location changed, it can now be found in
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/libclang.dylib
The /Developer
directory, among others, no longer exists by default. Everything is now packaged inside the XCode application, so that delta updates from the appstore work.
找不到Cursor_ref方法的问题
AttributeError: module 'clang.cindex' has no attribute 'Cursor_ref'
您需要将ref_node = clang.cindex.Cursor_ref(node)
更改为ref_node = node.get_definition()
,以避免获得AttributeError
,因为Cursor_ref
不再是clang.cindex
模块的属性。
Python代码find_ref.py
1 #!/usr/bin/env python 2 """ Usage: call with <filename> <typename> 3 """ 4 5 import sys 6 import clang.cindex 7 8 def find_typerefs(node, typename): 9 """ Find all references to the type named 'typename' 10 """ 11 if node.kind.is_reference(): 12 ref_node = node.get_definition() 13 if ref_node.spelling == typename: 14 print('Found %s [line=%s, col=%s]' % (typename, node.location.line, node.location.column)) 15 16 # Recurse for children of this node 17 for c in node.get_children(): 18 find_typerefs(c, typename) 19 20 index = clang.cindex.Index.create() 21 tu = index.parse(sys.argv[1]) 22 print('Translation unit:', tu.spelling) 23 find_typerefs(tu.cursor, sys.argv[2])
C++代码person.cpp
1 class Person { 2 }; 3 4 5 class Room { 6 public: 7 void add_person(Person person) 8 { 9 // do stuff 10 } 11 12 private: 13 Person* people_in_room; 14 }; 15 16 17 template <class T, int N> 18 class Bag<T, N> { 19 }; 20 21 22 int main() 23 { 24 Person* p = new Person(); 25 Bag<Person, 42> bagofpersons; 26 27 return 0; 28 }
运行
python3 find_ref.py person.cpp Person
