WebIntroduction. This program allows you to visualize an AST as it is generated by Clang when analyzing some source code. Clang does a pretty decent work of displaying a static AST in text mode, but the goal of this program is to make it easier to navigate this AST. Currently, it provides three major benefits: WebLibTooling is a Clang C++ library that supports the con-struction of tools that leverage the Clang parsing front-end [7]. LibTooling can be used to extract both syntactic and semantic information about a program by permitting access to the Clang abstract syntax tree (AST), which contains both syntactic and semantic information about the program
