Debugpy path mapping problems

[rlnt]

Hello,

first of all, I would like to thank you for this plugin. Finally being able to use Debugpy with PyCharm is a great relief, as I don't like the VSCode debugger very much.

There is only one small problem, and it may be due to the path mapping. If I have a Python source file and a breakpoint is hit in this file, then a second tab opens with the same file, but as read-only. Is it possible for the debugger to stop in the actual source file so I don't always have to jump back and forth between tabs?

My project is related to modding a game that uses Python in the modding interface. This modding framework also starts the debugpy server, which I then access via remote debug.
For proper version control, I have the source files of my modification in a separate folder and have linked it to the game folder via a symbolic link (Windows). For example, my source file is “C:\repositories\myproject\mod.py”, while the debugger breakpoint opens the read-only file in the following directory “C:\games\game1\mods\mod.py”. So I would have to somehow tell the debugger that this is the same path.

Is that possible?

Thanks so much!

If you like LSP4IJ DAP support, don't hesitate to add a review in the Jetbrains Marketplace to help us to promote LSP4IJ.

Have you the same problem with vscode?

Will do!

No, there was a setting in the launch profile where I could configure a path mapping between the local root and the remote root.

Sorry I don't understand if you declare pathMapping (like you did in vscode) in the Attach JSON editor of the DAP configuration of LSP4IJ, it doesn't work?

The only thing about mappings I found was here https://github.com/redhat-developer/lsp4ij/blob/main/docs/dap/user-defined-dap/python-debugpy.md#configure-file-mappings

But I am not sure how to configure my paths with it.

[angelozerr]

No it is different, it is just to provide the capability to add breakpoint to python file.

I suggest that you read doc of debugpy or doc of vscode with debugpy like https://code.visualstudio.com/docs/python/debugging#_remote-script-debugging-with-ssh

You will see that you can define a pathMappings.

Oh I didn't realize I can edit the JSON within the run config directly. That works, thank you!
One more question. Is it possible to stop the debug session without it terminating the attached process? In VSCode, there is a disconnect button for the debug run config but in PyCharm I only have stop and that seems to send a stop to my app as well.

It was a bug that I fixed. I plan to do a release next week, but you can install for now
