That API is documented at <a href="http://clang.llvm.org/doxygen/" target="_blank">http://clang.llvm.org/doxygen/</a> , but I understand that throwing that at somebody unfamiliar with it must be scaring (hint: the most commonly needed is the class hiearchy starting from clang::Stmt, as those are classes representing the program in the AST). I myself actually find it easier to read directly doxygen docs in the includes, mostly Decl*.h Expr*.h Stmt*.h in include/clang/AST/ . The API is however rather intuitive and straightforward, once one gets into it. And finding out how a particular piece of code is represented in the AST is a matter of compiling it with 'clang++ -Xclang -ast-dump' and matching the output to Clang classes. If you want to give it a try now, look under compilerplugins/ in the LO sources.</blockquote><div> I don't find this more intimidating than Eclipse's documentation for "org.eclipse.cdt.core.dom.ast.cpp" (Eclipse CDT's AST parser for C++) or "org.eclipse.jdt.core.dom" (Eclipse JDT's AST parser for Java). Only clang doc is harder to go through but it has nice graphics :). I might take a look at this. Thanks for sharing this info. </div></div>
