Invalid Window ID for DAP_REPL

[HudsonMC16]

Here is the relevant details on my setup:

DAP config in init.lua:

local dap = require('dap')
dap.adapters.python = {
  type = 'executable';
  command = os.getenv('USERPROFILE') .. '\\AppData\\Local\\nvim\\debugpy\\Scripts\\python.exe';
  args = { '-m', 'debugpy.adapter' };
}
dap.configurations.python = {
  {
    type = 'python';
    request = 'launch';
    name = "Launch file";
    program = "${file}";
    pythonPath = vim.fn.getcwd() .. '\\.venv\\Scripts\\python.exe';
    console = 'integratedTerminal';
  },
}
require('dapui').setup()

starting the DAP with :lua require('dap').continue() works wonderfully, and all the windows are properly setup. The DAP repl works great and as expected also. When .exit is executed at the repl, though, things break down. I added print(vim.inspect(sidebar_windows)) and print(vim.inspect(tray_windows)) here and here, and here is the output when .exit is run at the repl:

{
  [1003] = {
    float_defaults = {
      enter = true,
      height = 20,
      width = 80
    },
    name = "DAP REPL",
    on_close = <function 1>,
    on_open = <function 2>,
    setup = <function 3>
  }
}

    },
    name = "DAP REPL",
    on_close = <function 1>,
    on_open = <function 2>,
    setup = <function 3>
  }
}

Press ENTER or type command to continue

I haven't dug into it too much further than that, but maybe can over the weekend. I'm no lua pro, though. I figured I'd get it in front of you first. Few things I'm confused about:

1. 1003 is showing up in both the sidebar and tray window tables
2. None of the other windows are showing up in either table
3. 1003 appears to be a valid window id, so I'm not sure why nvim is complaining about an invalid window id.

I know windows is probably not your target platform, so let me know if I need to do any more testing to help with this.

And forgot to add: thanks so much for putting this together. Can't wait to switch to this from pdb and vimspector. I really like the UI you've put together.

Thanks for the great report and the feedback, great to hear from people using the project!

Don't worry this is just a simple fix, I've never used .exit before so I hadn't encountered it. It closes the REPL before nvim-dap-ui does and so it tries to close a window that doesn't exist anymore (hence the invalid ID).

[HudsonMC16]

@rcarriga ah interesting. So what's the intended workflow with this? Maybe I'm misunderstanding. If you're not using .exit, how do you exit or restart the debugger?

[rcarriga]

Oh that's a perfectly valid workflow, it's just that I do the vast majority of my debugging with vim-ultest and so I just follow the programs to completion as they are tests. I don't really have the need to exit from the program before it completes.
