import (
	"github.com/goplus/gox"
)

func ctxRef(pkg *gox.Package, name string) gox.Ref {
	return pkg.CB().Scope().Lookup(name)
}

pkg := gox.NewPackage("", "main", nil)

fmt := pkg.Import("fmt")

v := pkg.NewParam("v", types.Typ[types.String]) // v string

pkg.NewFunc(nil, "main", nil, nil, false).BodyStart(pkg).
	DefineVarStart("a", "b").Val("Hi").Val(3).EndInit(2).   // a, b := "Hi", 3
	NewVarStart(nil, "c").Val(ctxRef(pkg, "b")).EndInit(1). // var c = b
	NewVar(gox.TyEmptyInterface, "x", "y").                 // var x, y interface{}
	Val(fmt.Ref("Println")).
	/**/ Val(ctxRef(pkg, "a")).Val(ctxRef(pkg, "b")).Val(ctxRef(pkg, "c")). // fmt.Println(a, b, c)
	/**/ Call(3).EndStmt().
	NewClosure(gox.NewTuple(v), nil, false).BodyStart(pkg).
	/**/ Val(fmt.Ref("Println")).Val(v).Call(1).EndStmt(). // fmt.Println(v)
	/**/ End().
	Val("Hello").Call(1).EndStmt(). // func(v string) { ... } ("Hello")
	End()

gox.WriteFile("./foo.go", pkg)

This will generate a Go source file named ./foo.go. The following is its content:

package main

import fmt "fmt"

func main() {
	a, b := "Hi", 3
	var c = b
	var x, y interface {
	}
	fmt.Println(a, b, c)
	func(v string) {
		fmt.Println(v)
	}("Hello")
}
