Question
I generate some c++ codes, and store it in string, I want to construct an AST tree from the string using libclang. How to do it? I don't want to string into extra files.
Solution
OTHER TIPS
you can try such as the next code:
std::unique_ptr<ASTUnit> AST(tooling::buildASTFromCode("int x=10;x++;"));
TranslationUnitDecl *DC = AST->getASTContext().getTranslationUnitDecl();
if (DC) {
llvm::errs() << "---------dump begin----------\n";
DC->dump();
llvm::errs() << "---------dump end----------\n";
visitor.TraverseDecl(DC);
}
