python - ipython调试器: full traceback on interactive pdb?

我最近从ipython0.10切换到了ipython0.11。在ipython0.11中，当python调试器启用时(即使用%pdb)，我只看到一小段完整的追溯，而在ipython0.10中，我看到完整的追溯。据我所知，不能从pdb命令行直接访问完整的回溯-您可以使用'u'进行浏览，但不能直接看到它。

那么，有什么办法可以显示完整的追溯？如配置参数？

或者，更有用的是，有什么方法可以让ipython仅显示捕获的异常，而不是显示在代码中捕获的位置？

编辑:示例:

In [1]: pdb
Automatic pdb calling has been turned ON

In [2]: 1/0
> <ipython-input-2-05c9758a9c21>(1)<module>()
     -1 1/0

ipdb> q
---------------------------------------------------------------------------
ZeroDivisionError                         Traceback (most recent call last)
/Users/adam/<ipython-input-2-05c9758a9c21> in <module>()
----> 1 1/0

ZeroDivisionError: integer division or modulo by zero

我想看到q从pdb中出来之前的ZeroDivisionError。

最佳答案

您可以使用 sys.excepthook :

import sys

def exc_hook(type, value, traceback):
    print type

sys.excepthook = exc_hook

从 sys module documentation:



您也可以尝试将--xmode选项设置为Plain来启动ipython

从IPython reference:



这是一些示例用法。注意每个回溯的行数差异:

--xmode=Plain :

[ 19:55 jon@hozbox ~/SO/python ]$ ipython --xmode=Plain ipython-debugger-full-traceback-on-interactive-pdb.py
------------------------------------------------------------
Traceback (most recent call last):
  File "ipython-debugger-full-traceback-on-interactive-pdb.py", line 2, in <module>
    1 / 0
ZeroDivisionError: integer division or modulo by zero

--xmode=Context :

[ 19:55 jon@hozbox ~/SO/python ]$ ipython --xmode=Context ipython-debugger-full-traceback-on-interactive-pdb.py
---------------------------------------------------------------------------

----> 2 #!/usr/bin/python
      3 1 / 0
      4
      5

ZeroDivisionError: integer division or modulo by zero

--xmode=Verbose :

[ 19:54 jon@hozbox ~/SO/python ]$ ipython --xmode=Verbose ipython-debugger-full-traceback-on-interactive-pdb.py
---------------------------------------------------------------------------
ZeroDivisionError                         Traceback (most recent call last)

      3 1 / 0
      4
      5

并且不指定.py文件:

--xmode=Plain :

[ 19:55 jon@hozbox ~/SO/python ]$ ipython --xmode=Plain

In [1]: 1 / 0
------------------------------------------------------------
Traceback (most recent call last):

--xmode=Context :
