C++ Type Name Hints

Use this settings page to configure inlay hints for type names at variables and expressions.

General

Use compact type name presentation

Sometimes type names can be too long.

When this option is enabled, a shortened type name is displayed in the hint.

Hide if type name is evident from variable name

This option hides type name hints in cases similar to the following one:

Show type name hints in dependent C++ code

This option lets you show type name hints in cases similar to the following one:

Function return type after function calls

These hints will appear after methods if the next method in the chain is written in a new line:

Visibility

Use the selector to choose how inlay hints for method return type should be displayed in the editor: choose Default to apply the general visibility preference from the Editor | Inlay Hints | General page of JetBrains Rider settings , choose Show Always or Never Show to always show or hide hints, or choose Push-to-Hint to hide the hints by default but show them when you press and hold Ctrl.

Hide for single function calls and one-line function call chains

This option hides return type hints for single methods and one-liner chains.

Hide for the last function call when hint is irrelevant

This option hides an irrelevant return type hint for the last invocation.

Join hints for sequences of function calls with the same return type

This option hides repetitive return types in a sequence of invocations.

Mode

Choose whether function return type hints should be shown for the first or last call in a sequence.

Implicitly typed variables

This kind of hints is available for variables with automatically deduced type, which use the auto or decltype(auto) type specifiers.

Visibility

Use the selector to choose how type name hints for implicitly typed variables should be displayed in the editor: choose Default to apply the general visibility preference from the Editor | Inlay Hints | General page of JetBrains Rider settings , choose Show Always or Never Show to always show or hide hints, or choose Push-to-Hint to hide the hints by default but show them when you press and hold Ctrl.

Hide if type of variable is evident

This option is enabled by default so that hints of this kind will not appear where they are not necessary for understanding the type. For example, when the initializer is a constructor call, a constant, or an explicit cast.

Function return types in function declarations

The return types of functions can be automatically deduced from the return statement when they are omitted in the code. If this is the case, JetBrains Rider shows you a hint with the deduced type.

Function return types in function declarations

Use the Visibility selector to choose how type name hints in function returns should be displayed in the editor: choose Default to apply the general visibility preference from the Editor | Inlay Hints | General page of JetBrains Rider settings , choose Show Always or Never Show to always show or hide hints, or choose Push-to-Hint to hide the hints by default but show them when you press and hold Ctrl.

Lambda return types

The return type of a lambda expression is automatically deduced. If the lambda body contains one return statement, the return type will be deduced from the type of the return expression. Otherwise, the return type will be void.

Lambda return types

Use the Visibility selector to choose how type name hints in lambda expressions should be displayed in the editor: choose Default to apply the general visibility preference from the Editor | Inlay Hints | General page of JetBrains Rider settings , choose Show Always or Never Show to always show or hide hints, or choose Push-to-Hint to hide the hints by default but show them when you press and hold Ctrl.
