toggle background color for vim

toggle.vim

if exists("*ToggleBackground") == 0
	function ToggleBackground()
		if &background == "dark"
			set background=light
		else
			set background=dark
		endif
	endfunction

	command BG call ToggleBackground()
endif

nice

In lua the above can be writeen like:

local create_cmd = vim.api.nvim_create_user_command

create_cmd("ToggleBackground", function ()
    if vim.o.background == 'dark' then
        vim.cmd'set bg=light'
    else
        vim.cmd'set bg=dark'
    end
end, {})

thx
