Is there a simple way to change the file name format for new notes?

[trev-dev]

I like that I can use ,nn to create a new note on the fly. I don't like that the file names end up having the same case/spaces. I would prefer that:

Given a new note title such as "All about Neorg"
When I create a new note using ,nn and type in 'All about Neorg"
I then get a new note file with the name all-about-neorg.norg, with a title inside the norg file that reads "All about Neorg"

Is there a setting/hack I can use to do this simply?

I wrote a very nasty workaround a while ago, which might help you out. I'm not actually sure if it works right now.
This only replaces spaces with _ so change the code to your liking.

I ended up just using space contained file names as they didn't bring as much trouble as I initially thought.

local neorg_aug = vim.api.nvim_create_augroup("NeorgWritePre", { clear = true })

local function rename_file_with_spaces(_)
  vim.api.nvim_create_autocmd("BufWinEnter", {
    group = neorg_aug,
    pattern = "*.norg",
    desc = "Neorg: rename file if filename contains whitespace to underscore",
    callback = function()
      local file = vim.fn.expand("<afile>")
      local dir, file_name = vim.fn.fnamemodify(file, ":p:h"), vim.fn.fnamemodify(file, ":p:t")

      local new_name = string.gsub(file_name, " ", "_")
      -- TODO: you may want to string.lower here

      if file_name == new_name then
        return
      end
      local res, err = os.rename(dir .. "/" .. file_name, dir .. "/" .. new_name)
      if not res then
        vim.notify(err or string.format("Failed to rename: `%s` -> `%s`", file_name, new_name), vim.log.levels.ERROR)
        return
      end
      vim.schedule(function()
        vim.api.nvim_buf_delete(0, {})
        vim.cmd.edit(dir .. "/" .. new_name)
      end)
    end,
  })
end```
