Code Completion

Use this page to configure code completion and parameter information.

Item	Description
Match case	Select this option if you want letter case to be taken into account when suggesting matches for code completion. Choose whether you want to match case for the first letter of for all letters.
Automatically insert single suggestions for	Choose whether you want to automatically complete your code if there's just one code completion suggestion for basic and/or type-matching completion.
Sort suggestions alphabetically	Choose this option if you want to sort items in the suggestions list in the alphabetical order instead of sorting them by relevance. You can change this behavior at any time by clicking the or icons in the suggestion list.
Show suggestions as you type	Select this checkbox if you want the suggestions list to be invoked automatically, without having to call completion explicitly.
Insert selected suggestion by pressing space, dot, or other context-dependent keys	Select if you want to insert the selected suggestion by typing certain keys that depend on the language, your context, and so on.
Show the documentation popup in	Select this checkbox to have GoLand automatically show a popup for each item in the suggestions list with the documentation for the class, method, or field currently highlighted in the lookup list. In the field to the right, specify the delay (in milliseconds), after which the popup should appear.
Machine Learning-Assisted Completion	Select if you want to utilize machine learning models to rank most suitable items higher in the suggestions list. This feature is experimental, so ranking might not change noticeably.

JavaScript

In this area, configure code completion in the JavaScript context. Learn more from Configuring code completion settings.

Item	Description
Only type-based completion	By default, GoLand suggests completion for symbols regardless of their types. With this approach, in complicated cases the list shows multiple completion variants. To make completion more precise, select the checkbox. The completion list will strongly depend on the GoLand inference. As a result, the list may remain empty in case of poor inference.
Suggest items with optional chaining for nullable types	By default, GoLand suggests completion for symbols with the optional chaining operator (?). To suppress showing such suggestions, clear the checkbox.
Expand method bodies in completion for overrides	By default, when you want to override a method from the parent class or interface and select this method from the list of completion suggestions, GoLand automatically adds parameters, generates a `super()` call, and adds the type information, if possible. Clear the Expand method bodies in completion for overrides checkbox to suppress automatic generation of method bodies for overrides during completion.
Completion of names	Suggest variable and parameter names: By default, the checkbox is cleared. When it is selected, GoLand suggests names for new variables and parameters during their declaration. These suggestions are based on the names of classes, types, and interfaces that are defined in your project, in the libraries you are using, and in standard APIs. Suggest names for class fields The option is by default turned off. Add type annotations for suggested parameter names: Select this checkbox to supply each completion suggestion with information on its type. The checkbox is available only when the Suggest variable and parameter names checkbox is selected.

Parameter Info

Item	Description
Show the parameter info popup in	Select this checkbox to have GoLand automatically show a popup with all available method signatures when an opening bracket is typed in the editor, or a method is selected from the suggestions list. In the text field to the right, specify the delay (in milliseconds) after when the popup window should appear. If this checkbox is not selected, use `Ctrl+P` to show parameter info.
Show full method signatures	If this checkbox is selected, the parameter info displays full signatures, including method name and returned type.
