Jupyter cell debugging does not support "step into" the third party library code with "justmycode:false"

[ckxckx]

Jupyter cell debugging does not support "step into" the third party library code with "justmycode:false" in launch.json.

Please fix it !

can not step into lib code even setting:
"jupyter.debugJustMyCode": false

This is explicitly hardcoded here:

vscode-jupyter/src/client/debugger/jupyter/debuggingManager.ts

Line 299 in 350a17c

justMyCode: true,

Likely because stepping into 3rd party code isn't going to do what you want. It will end up stepping through the display hooks for ipython and not the 3rd party library.

@int19h is there a way to add libs to the 'justMyCode' list?

I don't think we have anything documented for this, but pydevd exposes some environment variables to control this. Presumably you'd want the library to debug to be listed in IDE_PROJECT_ROOTS, but I'm not sure how this will interact with the default exclusion filters - @fabioz should know.

I wonder if perhaps the Jupyter extension should be using the exclusion filters on a lower level to specifically exclude all those display hooks, while leaving "justMyCode" setting to the user?

That sounds interesting too. How do we set exclusion filters?

[int19h]

It's all in the same code linked above, so currently, also via env vars (or using pydevd APIs). But we can always plumb that API through debugpy as needed.

Thanks, where does the justMyCode flag actually come in, is it implemented using those flags?
