如何將IPython shell嵌入到使用curses模塊的Python程序中？

Question

我在我的curses程序中按'i'時試圖放入IPython shell。爲了達到這一點，我設置了一個curses窗口和其他幾個窗口。我可以使用while循環與程序進行交互，並根據按鍵進行操作。

從Embedding IPython我借了一些代碼，你可以在塊的開頭和結尾看到。

... 

from IPython.Shell import IPShellEmbed 
ipshell = IPShellEmbed() 

... 

def main(): 

stdscr = curses.initscr() 

(win_maxy, win_maxx) = stdscr.getmaxyx() 

onethirds_win_width = int(math.floor(win_maxx/3)) 
half_win_heigth = int(math.floor(win_maxy/2)) 

begin_x = 0; begin_y = 0 
height = half_win_heigth ; width = onethirds_win_width 
download_win = curses.newwin(height, width, begin_y, begin_x) 
download_win.border() 
download_win.refresh() 
download_list_win = download_win.subwin(height-2, width-2, begin_y+1, begin_x+1) 

begin_x = (half_win_heigth-1)+2 ; begin_y = 0 
height = half_win_heigth ; width = onethirds_win_width 
configs_win = curses.newwin(height, width, begin_y, begin_x) 
configs_win.border() 
configs_win.refresh() 
configs_list_win = configs_win.subwin(height-2, width-2, begin_y+1, begin_x+1) 

begin_x = 0 ; begin_y = win_maxy-1 
height = 1 ; width = win_maxx 
status_win = curses.newwin(height, width, begin_y, begin_x) 

begin_x = 0 ; begin_y = half_win_heigth+2 
height = 1 ; width = win_maxx 
input_win = curses.newwin(height, width, begin_y, begin_x) 
input_win_textbox = curses.textpad.Textbox(input_win) 
#curses.textpad.rectangle(stdscr, begin_y, begin_x, begin_y+height+1, begin_x+width+1) 

curses.noecho() 
curses.cbreak() 
stdscr.keypad(1) 

stdscr.addstr(half_win_heigth+5, 5, "MCP Fetcher. Ready.") 
stdscr.refresh() 

while 1: 
    c = stdscr.getch() 
    download_win.border() 
    if c == ord('q'): break # Exit the while() 
    elif c == ord('c'): stdscr.clear() # Clear the screen 
    elif c == ord('i'): 
     curses.nocbreak(); stdscr.keypad(0); curses.echo() 
     ipshell() # Start the ipython shell 
     curses.noecho(); curses.cbreak(); stdscr.keypad(1) 

...

和代碼繼續。

問題是IPython shell沒有echo，沒有cbreak等。我該如何解決這個問題？

感謝
