I'm trying to use the TelnetRepl in an android Service but cannot
figure out how to put bindings into the environment


import android.app.Service
import android.content.Intent
import android.os.Binder
import android.os.IBinder
import android.util.Log
import gnu.expr.Language
import gnu.mapping.Environment
import gnu.mapping.Symbol
import kawa.TelnetRepl

/**

class ReplService : Service() {
    val TAG = "ReplService"
    override fun onCreate() {
        Thread(Runnable {
            Log.e(TAG, "repl")
            try {
                val ssocket = java.net.ServerSocket(9999)
                val port = ssocket.localPort
                val lang = Language.getInstance(null as String?)
                Language.setDefaults(lang)
                Log.e(TAG, "repl listening on port " + port)

                while (true) {
                    Log.e(TAG, "waiting ... ")
                    val client = ssocket.accept()
                    Log.e(TAG, "got connection from "
                            + client.inetAddress
                            + " port:" + client.port)
                    TelnetRepl.serve(lang, client)
                    val env = Environment.getCurrent()
                    env.put(Symbol.makeUninterned("context", null),
applicationContext)
                }
            } catch (ex: java.io.IOException) {
                Log.e(TAG, ex.toString())
                throw Error(ex.toString())
            }
        }).start()
    }

    override fun onBind(i: Intent): IBinder {
        return Binder();
    }
}

I can telnet to it but the "context" symbol is not available

#|kawa:4|# context
/dev/stdin:4:1: unbound location: context

at java.lang.Thread.run(Thread.java:764)

Do I have the wrong environment? if so how to get the correct environment?

thanks,
Sonny
