mem-cpu-load component

[pbnj]

Similar to tmux-mem-cpu-load, it would be nice if there is a way to show memory and cpu consumption in the statusline.

At first, I tried doing it very crudely:

local function mem_cpu()
  return vim.call('system', 'tmux-mem-cpu-load')
end

require('lualine').setup({
  sections = {
    lualine_x = { mem_cpu }
  }
})

But, performance was terrible.

So, I tried reducing the refresh interval to 3 seconds:

local function mem_cpu()
	return vim.call('system', 'tmux-mem-cpu-load')
end

require('lualine').setup({
	sections = {
		lualine_x = { mem_cpu }
	}
})

if _G.Statusline_timer == nil then
    _G.Statusline_timer = vim.loop.new_timer()
else
    _G.Statusline_timer:stop()
end
_G.Statusline_timer:start(0, 3000, vim.schedule_wrap(function() vim.api.nvim_command('redrawstatus') end))

But, that did not seem to be any better.

I am curious if anyone else has thought about a similar idea or knows of a tip/trick to make this work?

You are still executing the command on every redraw by calling redraw in timer you're actually making it worse in this case. Do something like this

• have a cache variable string the result in local scope
• use a function as component that displays from the cache var
• setup a separate function in timer that updates the cached value.
