This parsing example parses GO code at runtime:

package main

import (
    "fmt"
    "go/parser"
    "go/token"
)

func main() {
    fset := token.NewFileSet() // positions are relative to fset

    src := `package foo

import (
    "fmt"
    "time"
)

func bar() {
    fmt.Println(time.Now())
}`

    // Parse src but stop after processing the imports.
    f, err := parser.ParseFile(fset, "", src, parser.ImportsOnly)
    if err != nil {
        fmt.Println(err)
        return
    }

    // Print the imports from the file's AST.
    for _, s := range f.Imports {
        fmt.Println(s.Path.Value)
    }

}
