[cfe-dev] How to Provide C Source Code Files as Input to RecursiveASTVisitor based CLANG Tool

[Firat Kasmis via cfe-dev]

Hi Sunny,

you can do as follows:

static cl::OptionCategory MySampleCategory("clang-tool options");

int main(int argc, const char *argv[])
{
  CommonOptionsParser OptionsParser(argc, argv, MySampleCategory);
  ClangTool Tool(OptionsParser.getCompilations(),
OptionsParser.getSourcePathList());

  return Tool.run(newFrontendActionFactory<FindNamedClassAction>().get());
}

Take a look at Matchers as well. It might be more handy for you:

Of course, you could also just read the specified files into a string
variable and pass it to runToolOnCode:

std::string FileContent;
// fill it from the files specified in argv

runToolOnCode(new FindNamedClassAction, FileContent);
