How to integrate with iron.nvim

[noprompt]

Here is how I was able to get edgy working with iron.

In your iron configuration define repl_open_cmd as follows:

{
  config = {
    repl_open_cmd = function(bufnr)
        -- iron doesn't set the filetype for the buffers it creates so we need
        -- to provide one.
        vim.api.nvim_set_option_value("filetype", "iron", { buf = bufnr })
        -- Create a window and return it's id.
        return require("iron.view").split.vertical.botright(40)(bufnr)
      end,
    }
}

You can now wire up iron to edgy. For example, here is what I have currently:

{
  bottom = {
    {
      title = "Iron",
      ft = "iron",
      size = { height = 0.4 },
      filter = function(buf)
        -- We only want buffers which iron is managing.
        return require("iron.lowlevel").repl_exists({ bufnr = buf })
      end,
    }
  }
}

If there is a better way to do this, please let me know!
