impast
A library for package AST importing.
Installation
go get -u github.com/orisano/impastHow to use
package main
import (
"fmt"
"log"
"github.com/orisano/impast"
)
func main() {
pkg, err := impast.ImportPackage("io")
if err != nil {
log.Fatal(err)
}
it := impast.FindInterface(pkg, "Writer")
if it == nil {
log.Fatalf("io.Writer not found")
}
methods := impast.GetRequires(it)
for _, method := range methods {
fmt.Println(method.Names[0].Name)
}
// Output:
// Write
}Useful commands
