Is it possible to render nothing when render function return nil

[fitrh]

For example, I have something like this in my render function

  if props.focused then
    local ok, gps = pcall(require, "nvim-gps")
    if not ok or not gps.is_available() or (gps.get_location() == "") then
      return nil
    end

    return { gps.get_location() }
  end

The result

I still get a little box when the result is nil

Is it possible to completely get rid of the render result when we return nil ?

I had the same issue when I wanted to hide incline when my cursor is on the same line, so it doesn't hide source.

My current workaround is an autocmd:

vim.api.nvim_create_autocmd({ "CursorMoved", "CursorMovedI" }, {
	group = vim.api.nvim_create_augroup("hide_incline_on_first_line", {}),
	buffer = 0,
	callback = function()
		local incline = require("incline")
		if vim.fn.line(".", vim.api.nvim_get_current_win()) == 1 then
			incline.disable()
		else
			incline.enable()
		end
	end,
})

There is probably a better way to do this.

( I also probably will start digging into incline itself for a PR, but that takes more time)

In addition to fitrh’s suggestion, I plan to add a configuration option to hide the incline window if the cursor is on the same line.

oh, that would be awesome! ❤️

This isn’t currently possible but it’s a great idea. I will implement it soon.

Update:

This is now implemented. If render returns nil, that statusline is temporarily hidden until render returns non-nil. See :help incline-config-render.

Also added config.hide.cursorline. See :help incline-config-hide.cursorline.

By the way @fitrh I really like your idea of using Incline to display gps info. Would you like to contribute a screenshot/screencast to the showcase? And if so, would it be okay if I add it to the README?

[fitrh]

Sure, I will do it when I have time
