Overview

Package inspect defines an Analyzer that provides an AST inspector (golang.org/x/tools/go/ast/inspect.Inspect) 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
}
