title: Diagnostics - Errors and Warnings in Zed description: View and navigate errors, warnings, and code diagnostics from language servers in Zed. #

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

"diagnostics_max_severity": null

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

The scrollbar ones are configured with the

"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

"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

"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

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

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