Hard task: how to show diagnostic warnings and errors by their count numbers without icons?

[nickshiro]

I would like to show the number of errors or warnings instead of icons. Simply yellow and red numbers for each file. I've tried everything(

probably in-scope enough to be built-in but until i get around to that, you can write your own custom ui components. This is the diagnostics one for example:

neo-tree.nvim/lua/neo-tree/sources/common/components.lua

Line 188 in f3e8633

M.diagnostics = function(config, node, state)

There's a custom components page if you want an example of how to add your own to your config

the diag_state table contains all that you would need. diag_state.Error and diag_state.Warn should give you number of errors/warnings respectively if i'm not mistaken.
