I am trying to get hold on Clang. So, I would like to view the AST generated by Clang after parsing the given program. Is it possible to dump AST in .dot or .viz format? Is there any tool out there?

Clang's AST nodes are modeled on a class hierarchy that does not have a common ancestor. Instead, there are multiple larger hierarchies for basic node types like Decl and Stmt. Many important AST nodes derive from Type, Decl, DeclContext or Stmt, with some classes deriving from both Decl and DeclContext.
Running clang-check without any options runs the -fsyntax-only mode (checking for correct syntax). Only if you specify -analyze , the static analysis tool is executed, see http://clang-analyzer.llvm.org/available_checks.html for a full list of executed checks.
clang-query is a tool that allows you to quickly iterate and develop the difficult part of a matcher. Once the design of the matcher is completed, it can be transferred to a C++ clang-tidy plugin, similar to the ones in mozilla-central.
The method with -cc1 invocation will have problem with includes and recognizing C++.
For full-featured parsing, use:
clang -Xclang -ast-dump file.cpp If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
