This capability relies on bytecode indexes, and can also be used to locate the following hidden elements that are not present in the source code “as is”: You can navigate from implicits definitions to their usages using the Find Usages action. Minimal unique type to show method chains: you can change the number of unique types in a chain that are required to show the hints. Hide identical types in method chains: with this option you can omit hints when the type is obvious. Show method chain hints: clear this option to disable the hints.Īlign type hints in method chains: by default, IntelliJ IDEA displays the hints as a separate column, which helps you easily view the type flow. In the Settings/Preferences dialog ( Ctrl+Alt+S), go to Editor | Inlay Hints | Scala.įrom the list, select Method chains and select or clear the following options:

From the same menu you can control how to display the inlay hints and what hints to hide. You can disable the inlay hints if you right-click the hint and from the context menu uncheck the Show method chain inlay hints option. IntelliJ IDEA automatically displays type hints for long expression chains. Press Ctrl+Alt+Shift+ - to collapse the hints.

If you press the same shortcut again, IntelliJ IDEA expands the implicit hints to show you more detailed information. In the editor, right-click the hint and from the popup menu, select the appropriate action in order to expand the existing hint, disable the mode, or to see the implicit arguments.Īlternatively, while in the editor, you can press Ctrl+Alt+Shift+ + to enable the implicit hints. On the main toolbar, select View | Show Implicit Hints. IntelliJ IDEA lets you enable, expand and collapse editor hints for implicit conversions and arguments to help you read your code. Turn simple string into the interpolated one adding a variable reference. On the Scala page, select the Multi-line strings tab. In the main menu, select File | Setting | Editor | Code Style | Scala. Use the Multi-line strings tab in Scala settings to set a different format for multi-line strings' options such as Margin char indent or disable a multi-line strings support. You can inject languages into multiline string literals with margins. For more information, refer to the Language Injections documentation. Use the Inject Language/Reference intention to insert a language or a reference into your multi-line string literals. This intention lets you keep the caret at the correct place on the next line in the multi-line strings regardless of what operating system you have at the moment.Įnter a multi-line string, press Alt+Enter and select the appropriate intention from the list. The white spaces are also preserved.Īdd the. The stripMargin method removes the left-hand part of a multi-line string up to a specified delimiter. If you press Enter, it will automatically invoke the stripMargin method. To enter a multi-line string, type triple quotes in your editor.

Select Convert to 'string' and press Enter. Press Alt+Enter to open the list of intentions. You also can convert the multi-line string into the regular string. Insert gap with concatenation ('+ +') into a string.Ĭonvert a string into a multi-line string using the Convert to '''string''' intention and vice versa.Ĭonverting to multi-line strings removes escaped sequences such as '\' or ' '.Įnter your string, press Alt+Enter and from the list of intentions, select Convert to '''string'''. Use a Scala worksheet to quickly evaluate your results. You can add different intentions for strings, perform different actions, and set a different format for multi-line strings. IntelliJ IDEA lets you use different Scala intention actions, convert your code from Java to Scala, and use different Scala templates while working in the IntelliJ IDEA editor.
