# Diagnostics

Zed 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.

# Regular diagnostics

By default, Zed displays all diagnostics as underlined text in the editor and the scrollbar.

Editor diagnostics could be filtered with the

```json 
"diagnostics_max_severity": null
```

editor setting (possible values: `"off"`, `"error"`, `"warning"`, `"info"`, `"hint"`, `null` (default, all diagnostics)).

The scrollbar ones are configured with the

```json 
"scrollbar": {
  "diagnostics": "all",
}
```

configuration (possible values: `"none"`, `"error"`, `"warning"`, `"information"`, `"all"` (default))

The diagnostics could be hovered to display a tooltip with a full, rendered diagnostic message.
Or, `editor::GoToDiagnostic` and `editor::GoToPreviousDiagnostic` could be used to navigate between diagnostics in the editor, showing a popover for the currently active diagnostic.

# Inline diagnostics (Error lens)

Zed supports showing diagnostics as a lens to the right of the code.
This is disabled by default, but can either be temporarily turned on (or off) using the editor menu, or permanently, using the

```json 
"diagnostics": {
  "inline": {
    "enabled": true,
    "max_severity": null, // same values as the `diagnostics_max_severity` from the editor settings
  }
}
```

# Other UI places

## Project Panel

Project panel can have its entries coloured based on the severity of the diagnostics in the file.

To configure, use

```json 
"project_panel": {
  "show_diagnostics": "all",
}
```

configuration (possible values: `"off"`, `"errors"`, `"all"` (default))

## Editor tabs

Similar to the project panel, editor tabs can be colorized with the

```json 
"tabs": {
  "show_diagnostics": "off",
}
```

configuration (possible values: `"off"` (default), `"errors"`, `"all"`)
