How to add an import statement in a Go wrapper generated by SWIG-CodePudding

I have a wrapper generated by SWIG for the Go language. In this wrapper, I inserted some Go code that needs the package reflect. Consequently, I need to add the line import "reflect" in this wrapper. Is there an example that illustrates how to do this in SWIG?

CodePudding user response：

I think what you want is in section 23.4.10 Adding additional go code namely the part about

If you need to import other go packages, you can do this with %go_import. For example...

%go_import("fmt", _ "unusedPackage", rp "renamed/package")

%insert(go_wrapper) %{

func foo() {
  fmt.Println("Some string:", rp.GetString())
}

// Importing the same package twice is permitted,
// Go code will be generated with only the first instance of the import.
%go_import("fmt")

%insert(go_wrapper) %{

func bar() {
  fmt.Println("Hello world!")
}

%}
