Re: Superbe article !

Voilà:

#include <clang/Frontend/FrontendAction.h>
#include <clang/Tooling/Tooling.h>
#include <clang/AST/ASTConsumer.h>
#include <clang/AST/Decl.h>
#include <iostream>
struct MyASTConsumer : clang::ASTConsumer {
 void HandleTagDeclDefinition(clang::TagDecl* D) override {
 // if it's a struct or a class
 if (D->isRecord())
 std::cout << "Found a class: " << D->getNameAsString() << std::endl;
 }
};
struct MyAction : clang::ASTFrontendAction {
 virtual clang::ASTConsumer *CreateASTConsumer(clang::CompilerInstance &CI,
 llvm::StringRef) override {
 return new MyASTConsumer();
 }
};
int main(int argc, const char **argv)
{
 std::vector<std::string> Argv;
 // Just forward all the arguments to the tool
 for (int I = 0 ; I < argc; ++I)
 Argv.push_back(argv[I]);
 clang::FileManager FM({"."});
 clang::tooling::ToolInvocation Inv(Argv, new MyAction, &FM);
 return !Inv.run();
}

Ça s'utilise comme ça:

./a.out mylib.h -c -x c++ -I/usr/include

Et ça affiche toute les classes (y compris toutes celle de la stdlib)
