Python libclang怎么用编译数据库？

Question

这个问题已经被问过两次了，一个答案似乎很受欢迎：

另一个没那么多： How to use compile_commands.json with llvm clang (version 7.0.1) python bindings?

然而，这两种解决方案似乎都不起作用。如果您尝试最流行的解决方案，即如果您这样做：

    index = clang.cindex.Index.create()
    compdb = clang.cindex.CompilationDatabase.fromDirectory('/home/makogan/neverengine_personal/build/')
    file_args = compdb.getCompileCommands(path)
    translation_unit = index.parse(path, file_args)

你会得到这个错误：

Traceback (most recent call last):
  File "/home/makogan/neverengine_personal/Source/../Scripts/notebook_generator.py", line 178, in <module>
    main()
  File "/home/makogan/neverengine_personal/Source/../Scripts/notebook_generator.py", line 175, in main
    CreateNotebookFromHeader(args.path, args.out_path)
  File "/home/makogan/neverengine_personal/Source/../Scripts/notebook_generator.py", line 165, in CreateNotebookFromHeader
    nb['cells'] = GetHeaderCellPrototypes(path)
  File "/home/makogan/neverengine_personal/Source/../Scripts/notebook_generator.py", line 148, in GetHeaderCellPrototypes
    tokens = ExtractTokensOfInterest(path)
  File "/home/makogan/neverengine_personal/Source/../Scripts/notebook_generator.py", line 54, in ExtractTokensOfInterest
    translation_unit = index.parse(path, file_args)
  File "/home/makogan/.local/lib/python3.9/site-packages/clang/cindex.py", line 2688, in parse
    return TranslationUnit.from_source(path, args, unsaved_files, options,
  File "/home/makogan/.local/lib/python3.9/site-packages/clang/cindex.py", line 2783, in from_source
    args_array = (c_char_p * len(args))(*[b(x) for x in args])
  File "/home/makogan/.local/lib/python3.9/site-packages/clang/cindex.py", line 2783, in <listcomp>
    args_array = (c_char_p * len(args))(*[b(x) for x in args])
  File "/home/makogan/.local/lib/python3.9/site-packages/clang/cindex.py", line 109, in b
    return x.encode('utf8')
AttributeError: 'CompileCommand' object has no attribute 'encode'

如果您尝试第二个选项：

即这个：

print( list(iter(file_args).next().arguments))

您收到此错误：

AttributeError: 'iterator' object has no attribute 'next'

人们如何让第一个解决方案为他们工作？

正确的做法似乎是这样做：

    index = clang.cindex.Index.create()
    token_dict = {}
    compdb = clang.cindex.CompilationDatabase.fromDirectory('/home/makogan/neverengine_personal/build/')
    commands = compdb.getCompileCommands(path)

    file_args = []
    for command in commands:
        for argument in command.arguments:
            file_args.append(argument)

    translation_unit = index.parse(path, file_args)
