Alternate renderer for diagnostics.. WIki? about neo-tree-diagnostics.nvim

[mrbjarksen]

I've created a wiki page for this. This has given me a few ideas for new component options though, so I might revisit it later.

I have a second variation, this one also changes the file node style. I think these changes make the information easier to parse:

  require("neo-tree").setup({
    sources = {
      "filesystem",
      "buffers",
      "git_status",
      "diagnostics",
    },
    diagnostics = {
      components = {
        linenr = function(config, node)
          local lnum = tostring(node.extra.diag_struct.lnum + 1)
          local pad = string.rep(" ", 4 - #lnum)
          return {
            {
              text = pad .. lnum,
              highlight = "LineNr",
            },
            {
              text = "▕ ",
              highlight = "NeoTreeDimText",
            }
          }
        end
      },
      renderers = {
        file = {
          { "indent" },
          { "icon" },
          { "grouped_path" },
          { "name", highlight = "NeoTreeFileNameOpened" },
          --{ "diagnostic_count", show_when_none = true },
          { "diagnostic_count", highlight = "NeoTreeDimText", severity = "Error", right_padding = 0 },
          { "diagnostic_count", highlight = "NeoTreeDimText", severity = "Warn", right_padding = 0 },
          { "diagnostic_count", highlight = "NeoTreeDimText", severity = "Info", right_padding = 0 },
          { "diagnostic_count", highlight = "NeoTreeDimText", severity = "Hint", right_padding = 0 },
          { "clipboard" },
        },
        diagnostic = {
          { "indent" },
          { "icon" },
          { "linenr" },
          { "name" },
          --{ "source" },
          --{ "code" },
        },
      },
    },
  })

Looks great, I might use this myself! A wiki page sounds good. I'll set one up for documenting the default components and to showcase custom renderers.
