Re: Fast jump to error lines?

Hi Charles,

Thanks for your question.
May I ask where you found the link to this Mailing List ?
We have been trying to deprecate IPython-User in favor of
[email protected] which is much more active.

If you want more chance to get a response I would suggest asking
questions there.

I can still give you hint.
You probably do not want to parse the string, but to access the last
traceback raised.

see https://docs.python.org/3.5/library/sys.html#sys.last_traceback
and also the %debug magic of IPython.

Your request make sens imho, it will have a few edge cases (not all
file may exists), so if I was you I would open a feature request on
IPython, or even send a Draft PR. It's easier to review code and link
to existing code on GitHub.

How does that sound ?
