Problem Description

If I have cells in my code that take a long time to run, I want to avoid having to re run everything. Yet, if I want to debug just a part of my code, this is what I need to do. It would be great to use a mechanism similar to runcell (called debugcell) to debug a single cell.

The logic is implemented in https://github.com/spyder-ide/spyder-kernels/pull/112, but I wonder if there should be a keyboard shortcut or something to trigger that from spyder.

If https://github.com/spyder-ide/spyder-kernels/pull/112 is merged, should there be a mechanism to trigger the cell debugging? For now I type debugcell('mycell') in the console.

How about just a line in the menu and a keyboard shortcut?

The simplest way to start debugging a cell is to put

import pdb; pdb.set_trace()

anywhere on it. I don’t think we need more than that, do we?
