Enable/disable and suppress inspections

Some inspections may report problems that you currently do not want to see. In this case, you can disable or suppress them.

When you disable an inspection, you turn it off. It means that the code analysis engine stops searching project files for the problem that this inspection is designed to detect. Note that when you disable an inspection, you disable it in the current inspection profile; it remains enabled in other profiles.

Disable inspections

Disable an inspection in the settings

  1. In the Settings/Preferences dialog (Ctrl+Alt+S), select Editor | Inspections.

  2. Locate the inspection you want to disable, and clear the checkbox next to it.

    Enable inspection
  3. Apply the changes and close the dialog.

Disable an inspection in the editor

  1. Place the caret at the highlighted line and press Alt+Enter (or click the Intention action icon to use the intention action).

  2. Click the arrow next to the inspection you want to disable, and select Disable inspection.

    Disable an inspection in the editor

Disabling inspections in the Problems tool window

  1. In the Inspection Results tool window (after running code analysis), right-click the inspection you want to disable and select Disable inspection.

  2. Click the Filter resolved items icon to hide the disabled inspection alerts.

Suppress inspections

When you suppress an inspection, the code analysis engine doesn't highlight the problem found by this inspection in the specific piece of code (file, statement, function, or line).

Suppress an inspection in the editor

  1. Place the caret at the highlighted line and press Alt+Enter (or click the Intention action icon to use the intention action).

  2. Click the arrow next to the inspection you want to suppress, and select the necessary suppress action.

    Suppress inspection in the editor

You can also suppress inspections from the Results tool window.

For C/C++ code, CLion uses the #pragma clang diagnostic to suppress inspections. For example, when you suppress one of the Clang-Tidy inspections, modernize-avoid-bind, for a selected function, the following code appears above and below the declaration:

Suppressing an inspection for a function

Clang-Tidy inspections have the additional Suppress for line option, which adds the // NOLINT comment, forcing Clang-Tidy to ignore the current line:

Suppressing an inspection for a lilne

To re-enable a suppressed inspection, delete the #pragma lines or // NOLINT comments.

Disable highlighting, but keep the fix

Inspections have severities according to which they highlight code problems in the editor. You can quickly disable code highlighting for an inspection without opening the settings. In this case, the inspection remains enabled and provides a fix, but the severity changes to No highlighting (fix available).

  1. Place the caret at a code element highlighted by an inspection in the editor and press Alt+Enter.

    A list with available fixes and context actions opens. Locate the inspection fix that is marked with Intention action icon.

  2. Click the right arrow Platform impl general chevron right next to the fix to open the inspection's options and select Disable highlighting, keep fix.

The name of the inspection for which you are changing the severity is written above the inspection's options.

If you want to restore the highlighting, press Ctrl+Alt+S to open the IDE settings and select Editor | Inspections. Find the necessary inspection in the list and change its severity as you like. For more information, refer to Change inspection severity in all scopes.

Change the highlighting level for a file

  • By default, CLion highlights all detected code problems. Hover the mouse over the widget in top-right corner of the editor and select another level from the Highlight list:

    • None: turn highlighting off.

    • Syntax: highlight syntax problems only.

    • All Problems: (default) highlight syntax problems and problems found by inspections.

    Changing highlighting level for a file
  • You can also change the highlighting level from the main menu. Select or press Ctrl+Alt+Shift+H.
