 | `popup-border` | Draw border around `popup`, `menu`, `all`, or `none` | `none` |
 | `indent-heuristic` | How the indentation for a newly inserted line is computed: `simple` just copies the indentation level from the previous line, `tree-sitter` computes the indentation based on the syntax tree and `hybrid` combines both approaches. If the chosen heuristic is not available, a different one will be used as a fallback (the fallback order being `hybrid` -> `tree-sitter` -> `simple`). | `hybrid`
 | `jump-label-alphabet` | The characters that are used to generate two character jump labels. Characters at the start of the alphabet are used first. | `"abcdefghijklmnopqrstuvwxyz"`
+| `enable-diagnostics` | Whether to show diagnostics, such as inline diagnostics and overlay diagnostics | `true` |
 | `end-of-line-diagnostics` | Minimum severity of diagnostics to render at the end of the line. Set to `disable` to disable entirely. Refer to the setting about `inline-diagnostics` for more details | "disable"
 | `clipboard-provider` | Which API to use for clipboard interaction. One of `pasteboard` (MacOS), `wayland`, `x-clip`, `x-sel`, `win-32-yank`, `termux`, `tmux`, `windows`, `termcode`, `none`, or a custom command set. | Platform and environment specific. |
