| <h1>AST Matcher Reference</h1> |
| |
| <p>This document shows all currently implemented matchers. The matchers are grouped |
| by category and node type they match. You can click on matcher names to show the |
| matcher's source documentation.</p> |
| |
| <p>There are three different basic categories of matchers: |
| <ul> |
| <li><a href="#decl-matchers">Node Matchers:</a> Matchers that match a specific type of AST node.</li> |
| <li><a href="#narrowing-matchers">Narrowing Matchers:</a> Matchers that match attributes on AST nodes.</li> |
| <li><a href="#traversal-matchers">Traversal Matchers:</a> Matchers that allow traversal between AST nodes.</li> |
| </ul> |
| </p> |
| |
| <p>Within each category the matchers are ordered by node type they match on. |
| Note that if a matcher can match multiple node types, it will it will appear |
| multiple times. This means that by searching for Matcher<Stmt> you can |
| find all matchers that can be used to match on Stmt nodes.</p> |
| |
| <p>The exception to that rule are matchers that can match on any node. Those |
| are marked with a * and are listed in the beginning of each category.</p> |
| |
| <p>Note that the categorization of matchers is a great help when you combine |
| them into matcher expressions. You will usually want to form matcher expressions |
| that read like english sentences by alternating between node matchers and |
| narrowing or traversal matchers, like this: |
| <pre> |
| recordDecl(hasDescendant( |
| ifStmt(hasTrueExpression( |
| expr(hasDescendant( |
| ifStmt())))))) |
| </pre> |
| </p> |
| |
| <!-- ======================================================================= --> |
| <h2 id="decl-matchers">Node Matchers</h2> |
| <!-- ======================================================================= --> |
| |
| <p>Node matchers are at the core of matcher expressions - they specify the type |
| of node that is expected. Every match expression starts with a node matcher, |
| which can then be further refined with a narrowing or traversal matcher. All |
| traversal matchers take node matchers as their arguments.</p> |
| |
| <p>For convenience, all node matchers take an arbitrary number of arguments |
| and implicitly act as allOf matchers.</p> |
| |
| <p>Node matchers are the only matchers that support the bind("id") call to |
| bind the matched node to the given string, to be later retrieved from the |
| match callback.</p> |
| |
| <p>It is important to remember that the arguments to node matchers are |
| predicates on the same node, just with additional information about the type. |
| This is often useful to make matcher expression more readable by inlining bind |
| calls into redundant node matchers inside another node matcher: |
| <pre> |
| // This binds the CXXRecordDecl to "id", as the decl() matcher will stay on |
| // the same node. |
| recordDecl(decl().bind("id"), hasName("::MyClass")) |
| </pre> |
| </p> |
