Is it possible to configure MiniStatusline.config.diagnostic_levels?

[HoldenLucas]

mini.nvim/lua/mini/statusline.lua

Line 470 in c77359a

H.diagnostic_levels = nil

This line makes me think "no", but I started using mini today and haven't poked around very much. Ultimately I'd like to have separate sections for Error, Warning, and Hint, each tied to their respective highlights and shown only if their respective diagnostic lists are populated. Should I just define my own sections?

Also, thank you so so much for letting me replace ~100 lines of cmp config with a one liner. mini has already replaced 30% of my plugins.

Not at the moment, no. Not really because of that line (which is actually redundant, so thank you for pointing this out :) ).

I'll think for a while about adding this here somehow, as it seems like a reasonable usage. But currently I can't see a good way of doing this that is better than custom minimal section function. Here is my version for Neovim 0.6+ (add it before call to require('mini.statusline').setup()):

local diagnostic_level = function(level, prefix)
  if MiniStatusline.is_truncated(75) then
    return ''
  end

  local n = #vim.diagnostic.get(0, { severity = vim.diagnostic.severity[level] })
  return (n == 0) and '' or ('%s%s'):format(prefix, n)
end

After that it can be used something like this:

require('mini.statusline').setup({
  content = {
    active = function()
      -- ...
      local errors = diagnostic_level('ERROR', 'E')
      local warns  = diagnostic_level('WARN', 'W')
      local hints  = diagnostic_level('HINT', 'H')
      -- ...

      return MiniStatusline.combine_groups({
        -- ...
        { hl = 'DiagnosticError', strings = { errors } },
        { hl = 'DiagnosticWarn',  strings = { warns } },
        { hl = 'DiagnosticHint',  strings = { hints } },
        -- ...
    end,
  },
})

Edit: Oh, and thank you for kind words. nvim-cmp has much, much richer functionality though, and I'd suggest using 'mini.completion' only if you fully aware that it will be enough for you (because I most likely won't implement any new features for it, only bug fixes).
