B4J Question jShell - force reading stdOut inputStream

[Daestrum]

Is there a way to force the sh_stdOut to re-read the inputStream in case bytes have arrived since the last read.

If I use Process I can use this construct to ensure I get all the data.

Sub outputToCons
 Dim buf(consOut.BytesAvailable) As Byte
 If consOut.BytesAvailable > 0 Then
  consOut.ReadBytes(buf,0,consOut.BytesAvailable)
  Dim st As String = BytesToString(buf,0,buf.Length,"utf8")
  TextArea1.text = TextArea1.text & st
  TextArea1.SelectAll
  TextArea1.SetSelection(TextArea1.SelectionEnd,TextArea1.SelectionEnd)
 End If
 Sleep(20)
 If consOut.BytesAvailable>0 Then outputToCons
End Sub

Just wondered if there was a method within jshell I could use to do the same.

Not sure that I understand. All the data will be available through the StdOut event. You can use StringBuilder or BytesBuilder to collect the data and work with it whenever you like.

I will try and explain.

(trying jshell and directly coding a Process)

I am trying to get the output from a persistent command prompt window (started with /k).
The first data returned from it is ok, the headers for the shell.
But subsequent data returned on _stdOut in response to WriteToInputStream(…) is patchy, I may get the top part or the last few lines, but never the complete response unless it's really short.

Where does consOut come from?

Start with:

Sub shl_StdOut(StdOut (Buffer() As Byte, Length As Int)
 Log(BytesToString(Buffer, 0, Length, "utf8"))
End Sub

It should print the full logs.

Note that StdOut / StdErr events are raised on a different thread.

consOut is the stream from p.getInputStream() ( the process inputstream from the processbuilder)
