2 Introduction to the Clang AST
5 This document gives a gentle introduction to the mysteries of the Clang
7 Clang, or use tools that work based on Clang's AST, like the AST
19 Clang's AST is different from ASTs produced by some other compilers in
23 Clang's AST a good fit for refactoring tools.
25 Documentation for all Clang AST nodes is available via the generated
26 `Doxygen <http://clang.llvm.org/doxygen>`_. The doxygen online
28 make a search for clang and the AST node's class name usually turn up
30 clang ParenExpr).
35 A good way to familarize yourself with the Clang AST is to actually look
36 at it on some simple example code. Clang has a builtin AST-dump mode,
49 # Clang by default is a frontend for many tools; -Xclang is used to pass
51 $ clang -Xclang -ast-dump -fsyntax-only test.cc

95 Clang's AST nodes are modeled on a class hierarchy that does not have a

120 The two most basic nodes in the Clang AST are statements
121 (`Stmt <http://clang.llvm.org/doxygen/classclang_1_1Stmt.html>`_) and
123 (`Decl <http://clang.llvm.org/doxygen/classclang_1_1Decl.html>`_). Note
125 (`Expr <http://clang.llvm.org/doxygen/classclang_1_1Expr.html>`_) are
126 also statements in Clang's AST.
