不幸的是,完成者中的異常被捕獲在readline黑暗深處的某個地方.你可以試試這樣的東西：

import cmd

import traceback

def log_exceptions(fun):

def wrapped(*a, **kw):

try:

return fun(*a, **kw)

except Exception:

print traceback.format_exc()

raise

return wrapped

class App(cmd.Cmd):

@log_exceptions

def complete_foo(self,*arg):

# Uncommenting this line will silently crash the progrm

# making it hard to debug.

# Is there a way to force the program to crash ?

c = 2 + "ddda"

return "d dzpo idz dza dpaoi".split(" ")

$python c.py

(Cmd) foo Traceback (most recent call last):

File "c.py", line 7, in wrapped

return fun(*a, **kw)

File "c.py", line 20, in complete_foo

c = 2 + "ddda"

TypeError: unsupported operand type(s) for +: 'int' and 'str'

在調試完成器之后刪除裝飾器,因為從readline內部打印回溯可能會弄亂您的終端.

不,你不能輕易崩潰readline.
