Question

Hy, i am new here. I would like to know if there is a way to see where errors are in a file in my statusline (for example, line of the first error).

As i understand it right now "E4" means there are 4 errors, but on top of that I would like to know if I can see the actual lines.

Thank you.

Welcome!

Correct, here is the description.

... but on top of that I would like to know if I can see the actual lines.

It is possible in theory, but I wouldn't recommend having that. Statusline content is meant to be quickly executed and making that information available quickly is not entirely straightforward (requires caching data inside a dedicated DiagnosticChanged event and then going through the process of customizing whole statusline content).

What I would recommend is to use a dedicated mapping that navigates to the first error (or any diagnostic in general) in the current buffer. You can do that with 'mini.bracketed' and its diagnostic target:

• Pressing [D will navigate to the first diagnostic in the current regardless of its type (error, warning, info, or hint).

• Create custom mapping to navigate errors. Something like this:

  local make_bracketed_error = function(lhs, direction, desc)
    local rhs = function()
      MiniBracketed.diagnostic(direction, { severity = { vim.diagnostic.severity.ERROR } })
    end
    vim.keymap.set('n', lhs, rhs, { desc = desc })
  end
  
  make_bracketed_error('[E', 'first', 'First error')
  make_bracketed_error('[e', 'backward', 'Previous error')
  make_bracketed_error(']e', 'forward', 'Next error')
  make_bracketed_error(']E', 'last', 'Last error')

  This way you can press [E to go to first error in the buffer, 2[E to the second, [e - to the previous, ]e - to the next, ]E to the last.
