Here it is:
-----------------------------------------------
JSRuntime *rt;
JSContext *cx;
JSObject *glob, *it;
JSClass global_class = {
"global",0,
JS_PropertyStub,JS_PropertyStub,JS_PropertyStub,JS_PropertyStub,
JS_EnumerateStub,JS_ResolveStub,JS_ConvertStub,JS_FinalizeStub
};
rt = JS_NewRuntime(8L * 1024L * 1024L);
cx = JS_NewContext(rt, 8192);
JS_SetErrorReporter(cx, my_ErrorReporter);

glob = JS_NewObject(cx, &global_class, NULL, NULL);

JS_InitStandardClasses(cx, glob);

char line[500];
std::string cmd;
jsval rval;
JSString *str;
JSBool ok;
cmd = "";
while(gets(line))
{
    if (!*line)
    {
        JSScript *script;
        script = JS_CompileScript(cx, glob, cmd.c_str(),
strlen(cmd.c_str()),NULL,1);
        if (script)
        {
            ok = JS_ExecuteScript(cx, obj, script, &rval);
        }
         // alternatively: ok = JS_EvaluateScript(cx, glob, cmd.c_str(),
strlen(cmd.c_str()), "stdin", 1, &rval);
        if (ok)
        {
            str = JS_ValueToString(cx, rval);
            printf("script result: %s\n", JS_GetStringBytes(str));
        }
        cmd = "";
    }
    else
