Given that eglot has been part of the core emacs, I believe this is a long lasting wish for a lot of emacsers that has finally been fulfilled. (a stand alone DAP implementation that does not rely on LSP-mode)

How would you attach a DAP python debugger to a running instance of (i)Python? Is there some import debugpy; debugpy.start() command or similar?

[–] FreeAd7233@alien.top 1 points 1 year ago (1 children)

I believe this is out of the scope of the DAP protocol, I believe even VSCode cannot do it based on my understanding.

If you want to debug a running session, just use ipdb or pdb.

No it isn't. DAP can definitely do this. It can even attach to a PID.

This is what I complained about it in my post: I could not get dape to work with this.

I see, thanks for correcting me.

I see that this post https://github.com/Microsoft/vscode-python/issues/1078 suggested that debugpy can already attach to a local Python process.

Seems like in-process debuggers like iPDB are far more practical for interactive debugging of long running shells.
