This question has been asked before, but I couldn't find a good answer. So, I am trying to ask again.
I would like my ipdb to remember commands across sessions. Right now, it can pull up commands executed in Ipython sessions but not from old ipdb sessions. It would be a huge time saver, if I could have this feature.
Does anyone have a solution to this problem?
I had your same problem, so I forked the project and add a patch for persistent history. You can install the forked version of ipdb with pip:
pip install git+https://github.com/michelesr/ipdb.git
Just make sure that your IPython version is 5.0 or higher. Implementation info can be found in this article.
If you are wiling to use another debugger, trepan has does save history across sessions.
