 6# Diagnostics
 7
 8Zed gets its diagnostics from the language servers and supports both push and pull variants of the LSP which makes it compatible with all existing language servers.
 9
10# Regular diagnostics
11
12By default, Zed displays all diagnostics as underlined text in the editor and the scrollbar.
13
14Editor diagnostics could be filtered with the
15
16```json [settings]
17"diagnostics_max_severity": null
18```
19
20editor setting (possible values: `"off"`, `"error"`, `"warning"`, `"info"`, `"hint"`, `null` (default, all diagnostics)).
21
22The scrollbar ones are configured with the
23
24```json [settings]
25"scrollbar": {
26  "diagnostics": "all",
27}
28```
29
30configuration (possible values: `"none"`, `"error"`, `"warning"`, `"information"`, `"all"` (default))
31
32The diagnostics could be hovered to display a tooltip with full, rendered diagnostic message.
33Or, `editor::GoToDiagnostic` and `editor::GoToPreviousDiagnostic` could be used to navigate between diagnostics in the editor, showing a popover for the currently active diagnostic.
34
35# Inline diagnostics (Error lens)
36
37Zed supports showing diagnostic as lens to the right of the code.
38This is disabled by default, but can either be temporarily turned on (or off) using the editor menu, or permanently, using the
39
40```json [settings]
41"diagnostics": {
42  "inline": {
43    "enabled": true,
44    "max_severity": null, // same values as the `diagnostics_max_severity` from the editor settings
45  }
46}
47```
