| // Package inspect defines an Analyzer that provides an AST inspector |
| // (golang.org/x/tools/go/ast/inspector.Inspector) for the syntax trees |
| // of a package. It is only a building block for other analyzers. |
| // |
| // Example of use in another analysis: |
| // |
| // import ( |
| // "golang.org/x/tools/go/analysis" |
| // "golang.org/x/tools/go/analysis/passes/inspect" |
| // "golang.org/x/tools/go/ast/inspector" |
| // ) |
| // |
| // var Analyzer = &analysis.Analyzer{ |
| // ... |
| // Requires: []*analysis.Analyzer{inspect.Analyzer}, |
| // } |
| // |
| // func run(pass *analysis.Pass) (interface{}, error) { |
| // inspect := pass.ResultOf[inspect.Analyzer].(*inspector.Inspector) |
| // inspect.Preorder(nil, func(n ast.Node) { |
| // ... |
| // }) |
| // return nil, nil |
| // } |
