Vim中异步运行外部命令, 并在独立窗口中捕获其写向stdout/stderr的输出

import os,time,thread
import vim
import subprocess

def child(tid):
    pip = subprocess.Popen(['/home/zrf/test.sh'], shell=False, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
    while True:
        pip.poll()
        if pip.returncode != None:
            break
        line = pip.stdout.readline()

        # Store current window
        cur_win = vim.eval("winnr()")
        # Switch to the last window
        vim.command( vim.eval("winnr('$')") + "wincmd w" )
        vim.current.buffer.append(line)
        vim.command("redraw | $")
        # Restore the origin window
        vim.command( cur_win + "wincmd w")
        #time.sleep(0.1)

    # Store current window
    cur_win = vim.eval("winnr()")
    # Switch to the last window
    vim.command( vim.eval("winnr('$')") + "wincmd w" )
    vim.current.buffer.append("===== Finished =====")
    vim.command("redraw | $")
    # Restore the origin window
    vim.command( cur_win + "wincmd w")
