How could I set up a configuration to debug a package?

[Dyson]

I'm developing a Python package and would like to be able to run debugpy with this package, and debug it from within nvim, but I don't know how to do that.

I've got the package installed in a virtual environment (in editable mode) and can run it with python -m package_name. In PyCharm, I can set breakpoints in a file, run the package_name module, and debug from the breakpoints.

I don't know how to use debugpy, but I assume this is possible, and would love an example configuration for this behaviour. Thanks :)

If you want to debug a module instead of a file you'd use a configuration like this:

table.insert(require('dap').configurations.python, {
  type = 'python',
  request = 'launch',
  name = 'My custom launch configuration',
  module = 'module_name', -- 💀 change this to your module name
})
