- <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>
