package manhole provides a means to dynamically interact with registered Go objects in a live process, using a Lua shell.

Inspiration is mainly from Twisted's library of the same name: https://twistedmatrix.com/documents/current/api/twisted.conch.manhole.html

Example usage:

package main

import (
	"github.com/jtolds/go-manhole"
)

type MyType struct{ x int }

func (m *MyType) Set(x int) { m.x = x }
func (m *MyType) Get() int  { return m.x }

func main() {
	manhole.RegisterType("MyType", MyType{})
	panic(manhole.ListenAndServe(2222))
}

After running the above program, you can now connect via telnet or netcat to localhost:2222, and run the following interaction:

> x = MyType.new()
> print(x.Get())
0
> x.Set(5)
> print(x.Get())
5
