Smarter way to configure dap with debugpy for a module in Anaconda/Windows?

[bva99]

Hello!

I've been trying to configure a "Neovim python IDE" in the past 5 days with mixed success. And nvim-dap seems to work best with my setup. For some reason vimspector screws with my nvim-cpm...

I tried using nvim-dap-python, but I'm not really good at Lua, Vimscript, nor json, so I've been struggling to setup nvim-dap + debugpy for a module.

I use Anaconda in Windows, so I came up with the following config in config.lua for nvim-dap and would like some tips please! Maybe how to configure a .json for the current project once, check if it exists, then reuse it if it does?

Any way, here is how I configured dap.configurations in config.lua:

-- path to python.exe of reference debugpy, installed in the (base) environment in anaconda
local std_debugpy_python = vim.fn.environ()['CONDA_PYTHON_EXE']
dap.adapters.python = {
  type = 'executable';
  command = std_debugpy_python;
  args = { '-m', 'debugpy.adapter' };
}
local dap = require('dap')
dap.configurations.python = {
  {
    name = "Python: Launch module";
    type = 'python';
    request = 'launch';
    console = 'integratedTerminal';
    module = function() return vim.fn.input('Module name: '); end;
    python = function()
      if vim.fn.environ()['CONDA_DEFAULT_ENV'] ~= 'base' then
        local active_python = vim.fn.environ()['CONDA_PREFIX'] .. '\\python.exe'
        local yes_no_active_python = vim.fn.input('Use active python.exe (' ..
                                                  active_python
                                                  .. ')? (y/n) ')
        if yes_no_active_python == 'n' or yes_no_active_python == 'N' then
          local yes_no_default_python = vim.fn.input('Use default python (' ..
                                                     std_debugpy_python
                                                     .. ')? (y/n) ')
          if yes_no == 'n' or yes_no == 'N' then
           -- python.exe from user given path
            return vim.fn.input("Input python.exe path (cwd is " .. vim.fn.getcwd() .. "): ")
          else
            -- python.exe from base anaconda environment
            return std_debugpy_python
          end
        else
          -- python.exe from active anaconda environment
          return active_python
        end
      else
        local yes_no_default_python = vim.fn.input('Use default python (' ..
                                                   std_debugpy_python
                                                   .. ')? (y/n) ')
        if yes_no == 'n' or yes_no == 'N' then
         -- python.exe from user given path
          return vim.fn.input("Input python.exe path (cwd is " .. vim.fn.getcwd() .. "): ")
        else
          -- python.exe from base anaconda environment
          return std_debugpy_python
        end
      end
    end
  }
}

I do not know how to write the aforementioned .json using Lua/Vimscript. And after that, how to use dap.ext.vscode.load_launchjs?

Edit 1: had to add a condition to check whether the active environment is the base environment. Lot's of repeated code in my example, though

Edit 2: added a check for whether the base environment was active. And changed the environment variables to work in both cmd.exe and powershell
