Inlay Hints
Inlay hints are special markers that appear in the editor and provide you with additional information about your code, like the names of the parameters that a called method expects. Other types of hints inform you about annotations, method parameters, usages, and so on (depending on the language).
In inlay hints settings, you can configure what types of information you want to get in hints.
Change inlay hints appearance
In the Settings dialog (Control+Alt+S), go to , then select Inline hints.
Select the inlay hint type and state, and configure the font color and effects as required.
Reference
Code vision
Inheritors: shows the number of implementations for an interface and its method specifications. Click the
implementationshint to navigate to usages.
Usages: a number of usages of the class or method in the project. Click the
usageshint to navigate to usages.
Code author: code authors for a given element (for example, a type or a method). Click the name hint to open the Git blame functionality. Name of the author is displayed in the gutter.
Parameter names
Go
Show unnamed fields in structure values: show names of anonymous fields.
Show return parameters: show parameter names in
returnstatements.
Javascript
Non-literal arguments: show both literal and non-literal arguments, call expressions, objects, and array initializers.
Tagged template arguments: show tagged template arguments. This setting takes effect only over non-literal arguments and is only available when the Non-Literal arguments option is enabled.
For more information about arguments in tagged templates, refer to Tagged templates at mozilla.org.
Pipeline operators: show pipeline operators. For more information about pipeline operators, refer to Pipe Operator (|>) for JavaScript at github.com/.
SQL
In INSERT values: show names of columns in INSERT statements. Works only in query consoles, not as a language injection.
In SELECT expressions: show names of columns in SELECT statements that have context that sets column names. For example, SELECT statements inside CREATE VIEW and INSERT. Works only in query consoles, not as a language injection.
For * references: show names of columns for asterisk (*) references in SELECT statements that have context that sets column names For example, SELECT statements inside CREATE VIEW and INSERT. Works only in query consoles, not as a language injection.
For set operations (UNION, INTERSECT, EXCEPT): show names of columns in SELECT statements when they are used in set operations like UNION, INTERSECT, and EXCEPT. Works only in query consoles, not as a language injection.
TypeScript
Non-literal arguments: show both literal and named object parameters in method calls.
Tagged template arguments: show arguments in tagged templates.
Types
Javascript
Function return types in call chains: show function return types in call chains.
Type annotations: show type annotations. You can configure cases in which you want to show type annotations:
Variables and fields
Parameters in parentheses
Non-parenthesized single parameter
Function return types
TypeScript
Function return types in call chains: show function return types in call chains.
Type annotations: show type annotations. You can configure cases in which you want to show type annotations:
Variables and fields
Parameters in parentheses
Non-parenthesized single parameter
Function return types
Values
Go
Go: show values of constant definitions.
TypeScript
TypeScript: show values. Identifies places where special values (for example, null) are used.
URL path
Go
Go: show URL mappings in code. The icon provides quick access to URL testing and navigation options.
Other
Dockerfile
Docker run named stage: show an icon to quickly build or run a specific named stage in a Dockerfile.
Markdown
Table inlays: show horizontal and vertical bars around the table. Provides column and row actions.
SQL
Join cardinality: display the numerical relationship between rows of one table and rows in the other. Common cardinalities include one-to-one (
1<->1), one-to-many (1<->1..n), many-to-many(1..n<->1..n), and optional (0..n). The optional cardinality appears when the referring field is nullable.You can configure inlay hints for the following types of JOIN:
