Programmatische AST-Modifikation und Code-Inspektion mittels Go-Parser

package main
 
import (
	"fmt"
	"go/ast"
	"go/parser"
	"go/token"
)
 
func main() {
	fset := token.NewFileSet()
	src := `package sample; func Compute(x int) int { return x + 42 }`
	node, err := parser.ParseFile(fset, "", src, 0)
	if err != nil {
		panic(err)
	}
 
	ast.Inspect(node, func(n ast.Node) bool {
		if fn, ok := n.(*ast.FuncDecl); ok {
			fmt.Printf("Discovered function declaration: %s\n", fn.Name.Name)
		}
		return true
	})
