usage

    const sexpect = require("nv-cli-simple-expect");
    var [we,w,quit,cache] = sexpect();

    await we("login",":");
    await we("dev",  ":");
    await we("xxxxpasswd",  "# ");
    ....
    await quit()


    //when using a expect_ptrn THAT WILL NEVER MATCH, can goto the history-cache mode

    var p = we("ls-l", "xx$$%@!@%%@%")

    cache()  to get the history

APIS

  ExpectFunc  : async (
     data,       //newest  ondata
     cache,      //Array<String>   the last-element IS data
     cfg,        //---config WHEN init
     _pty        //---pty
  ) => Boolean

  Expect      : RegExp | String | ExpectFunc
       RegExp.test(data)
       String.includes(data)
       ExpectFunc(data,cache,cfg,_pty)

• async we(cmd:String,expect:Expect=DFLT_EXPECT):Array //auto append "\r"
• async w(cmd:String,expect:Expect=DFLT_EXPECT):Array
• async quit() //must be called WHEN finish using
• cache():Array //debug using , temperary ondata buf

EXAMPLE

    > await we("ls -l","# ")
    [
      'ls -l\r\n',
      'total 8\r\n',

        'root@dev2:~# '
    ]

    > await we("login",": ")
    [ 'login\r\n', 'dev2 login: ' ]

    > await we("root",": ")
    [ 'root\r\n', 'Password: ' ]

    > await we("my-xxxx-passwd","# ")

    await quit();  // !!------MUST CALL this BEFORE EXIT

dont resolve , history cache mode
