ok here is another try, which reads all output and errors too, in a separate thread and communicates via Queue.
I know it is not perfect(e.g. command with delayed output will not work and there output will get into next commnd for example tryr sleep 1; date) and replicating whole bash not trivial but for few commands i tested it seems to work fine
Regarding API of wx.py.shell I just implemented those method which Shell class was calling for Interpreter, if you go thru source code of Shell you will understand.
basically
here is the source code
import threading
import Queue
import time
import wx
import wx.py
from subprocess import Popen, PIPE
class BashProcessThread(threading.Thread):
def __init__(self, readlineFunc):
threading.Thread.__init__(self)
self.readlineFunc = readlineFunc
self.outputQueue = Queue.Queue()
self.setDaemon(True)
def run(self):
while True:
line = self.readlineFunc()
self.outputQueue.put(line)
def getOutput(self):
""" called from other thread """
lines = []
while True:
try:
line = self.outputQueue.get_nowait()
lines.append(line)
except Queue.Empty:
break
return ''.join(lines)
class MyInterpretor(object):
def __init__(self, locals, rawin, stdin, stdout, stderr):
self.introText = "Welcome to stackoverflow bash shell"
self.locals = locals
self.revision = 1.0
self.rawin = rawin
self.stdin = stdin
self.stdout = stdout
self.stderr = stderr
self.more = False
# bash process
self.bp = Popen('bash', shell=False, stdout=PIPE, stdin=PIPE, stderr=PIPE)
# start output grab thread
self.outputThread = BashProcessThread(self.bp.stdout.readline)
self.outputThread.start()
# start err grab thread
self.errorThread = BashProcessThread(self.bp.stderr.readline)
self.errorThread.start()
def getAutoCompleteKeys(self):
return [ord('')]
def getAutoCompleteList(self, *args, **kwargs):
return []
def getCallTip(self, command):
return ""
def push(self, command):
command = command.strip()
if not command: return
self.bp.stdin.write(command+"
")
# wait a bit
time.sleep(.1)
# print output
self.stdout.write(self.outputThread.getOutput())
# print error
self.stderr.write(self.errorThread.getOutput())
app = wx.PySimpleApp()
frame = wx.py.shell.ShellFrame(InterpClass=MyInterpretor)
frame.Show()
app.SetTopWindow(frame)
app.MainLoop()
