Code Editing

Highlight on Caret Movement

Matched brace

Select this checkbox to have JetBrains Rider highlight pairs of opening/closing braces when you place the caret right before the opening or right after the closing one. It also works for other delimiters such as brackets, square brackets, HTML and XML tags.

Current scope

Select this checkbox to have JetBrains Rider highlight the available scope for the code typed in the current caret location.

Usages of element at caret

Select this checkbox to have JetBrains Rider highlight all usages of the element at which the caret is currently positioned.

Formatting

Show notification after

• Reformatting code: select this checkbox to show a notification with changes in your code and a shortcut to the Reformat Code dialog every time you try to reformat the code. Otherwise, JetBrains Rider will reformat code silently.

• Imports optimization: select this checkbox to show notification with changes in your code. Otherwise, JetBrains Rider will optimize imports silently.

Refactorings

Specify refactoring options

• In the editor: select this option to enable the in-place refactoring mode for .NET languages.

  In the in-place mode, you specify all or most of the information necessary for the refactoring just by typing it, right in the editor. All the affected code fragments are highlighted and change as you type. If appropriate, additional refactoring options are selected in corresponding option boxes.

  The in-place refactoring mode is available for the following refactorings:

  • Extract Constant

  • Extract Field

  • Extract Method

  • Extract Variable

  • Rename

• In modal dialogs: select this option if you want to use the refactoring dialogs when you refactor code.

Preselect current symbol name for Rename refactoring

If this checkbox is selected, the old name of a symbol is selected in the editor or in the Rename dialog when the Rename refactoring is invoked for that symbol.

If the checkbox is cleared, the symbol to be renamed is not selected.

Show inline dialog for local variables

Select this checkbox if you want to display a confirmation dialog for the "Inline local variable" refactoring.

Error Highlighting

Error stripe mark min height (pixels)

In this field, specify the minimum size of the error and warning stripes.

Autoreparse delay (ms)

In this field, specify the time period after which JetBrains Rider starts reparsing the entered text.

The 'Next Error' action goes through

• The problems with the highest priority: select this option to have JetBrains Rider pass through the highest priority problems only (for example, errors), when executing Navigate | Next/Previous Highlighted Error command F2/Shift+F2.

• All problems: select this option to have JetBrains Rider pass through all the existing problems (for example, errors and warnings) sequentially.

Quick Documentation

Show quick documentation on hover

Select this checkbox to show quick documentation in JavaScript and TypeScript for the symbol when you move the mouse pointer over it. The quick documentation popup appears after the delay time specified in the Tooltip delay field.

Editor tooltips

Tooltip delay

Use this option to specify the delay, with which all editor tooltips appear on mouse hover. Editor tooltips include:

• Quick Documentation, which appears if the Show quick documentation on hover option is selected above on this settings page. You can press Ctrl+Q to invoke this tooltip with the keyboard.

• Error description, which appears on highlighted code issues if the design-time code inspection is enabled for the current file. You can press Ctrl+F1 to invoke this tooltip with the keyboard.
