The default traceback mode will now skip frames that are marked with
|
|
|
|
|
|
12
|
``__tracebackhide__ = True`` and show how many traceback frames have been
|
|
|
|
|
|
13
|
skipped. This can be toggled by using :magic:`xmode` with the ``--show`` or
|
|
|
|
|
|
14
|
``--hide`` attribute. It will have no effect on non verbose traceback modes.
|
|
|
|
|
|
15
|
|
|
|
|
|
|
16
|
The ipython debugger also now understands ``__tracebackhide__`` as well and will
|
|
|
|
|
|
17
|
skip hidden frames when displaying. Movement up and down the stack will skip the
|
|
|
|
|
|
18
|
hidden frames and will show how many frames were hidden. Internal IPython frames
|
|
|
|
|
|
19
|
are also now hidden by default. The behavior can be changed with the
|
|
|
|
|
|
20
|
``skip_hidden`` while in the debugger, command and accepts "yes", "no", "true"
|
|
|
|
|
|
21
|
and "false" case insensitive parameters.
