Code reference information

Definitions

In DataGrip, you can see where and how symbols, such as variables, arguments, or functions are defined in your project. For this purpose, the IDE features the Quick Definition popup.

  • To view definition of a symbol, select it in the editor and press Ctrl+Shift+I (or click View | Quick Definition).

Quick Definition popup

Alternatively, with the Ctrl key pressed, hover the cursor over any symbol. DataGrip displays the symbol as a link and shows its definition in a tooltip. Click this link to jump to the definition of the symbol.

Jump to the selected definition

You can open a definition in the Find tool window. To do so, click the Options icon in the top-right corner of the popup and click Open in Find tool window Open in Find Tool Window.

To open the source code of the definition for editing and close the popup, click the Options icon and then click Edit Edit Source (F4).

Parameter info

The Parameter Info popup shows the names of parameters in method and function calls. DataGrip automatically shows a popup with all available method signatures within 1 second (1000 milliseconds) after you type an opening bracket in the editor, or select a method from the suggestions list.

You can explicitly invoke the popup if it has closed or if your IDE is configured not to show the popup automatically. To do so, press Ctrl+P (or click View | Parameter Info).

View Parameter Info

Configure the parameter info popup

  1. In the Settings/Preferences dialog (Ctrl+Alt+S) , go to Editor | General | Code Completion.

  2. In the Show the parameter info popup in ... milliseconds field, specify the time in milliseconds after which the popup should appear.

If you don't want the popup to appear automatically, clear the Show the parameter info popup in ... milliseconds checkbox.

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).

Parameter hints

Some of the hints are enabled by default.

You can fine-tune inlay hints in Settings/Preferences | Editor | Inlay Hints.

Configure the parameter hints exception list

You can configure the list with exceptions for parameter hints.

  1. In the Settings/Preferences dialog (Ctrl+Alt+S) , select Editor | Inlay Hints and click the necessary language.

  2. Select Parameter hints in the list in the middle section.

    The options for configuring hints become available on the right.

  3. Add cases for which you do not want to see the hints to the Exclude list section. To add a case, click the inline hint in your code, press Alt+Enter and select Do not show hints for current method.

  4. Apply the changes and close the dialog.

Quick documentation

You can get quick information for any symbol or method signature right from the editor by means of the Quick Documentation feature that shows you code documentation in a popup as you hover the mouse over code elements.

View quick documentation

  • Hover the mouse over the necessary symbol in the editor.

  • You can also place the caret at the symbol and press Ctrl+Q (View | Quick Documentation).

    Press Ctrl+Q again to open this documentation in the Documentation tool window.

    Quick Documentation popup

Click the Show Options Menu icon in the popup to change the font size, display the quick documentation toolbar, or go to the source code.

Disable quick documentation on hover

By default, the quick documentation popup appears as you hover the mouse pointer over code elements. You can configure the IDE to display the popup only after you explicitly invoke the Quick Documentation feature.

  • In the Settings/Preferences dialog (Ctrl+Alt+S) , go to Editor | Code Editing | Quick Documentation and clear the Show quick documentation on hover checkbox.

    You can also click the Show Options Menu icon in the popup and disable the Show on Mouse Move option.

In this case, to view documentation for a symbol at caret, press Ctrl+Q or select View | Quick Documentation from the main menu. The documentation will be shown in the popup, but you can configure the IDE to display it in the tool window right away.

Open documentation in the tool window

With the default settings, pressing Ctrl+Q (View | Quick Documentation) opens quick documentation in a popup. You can change the setting to view it in the tool window.

  • In the quick documentation popup, click the Show Options Menu icon and disable the Show Documentation Popup First option.

  • In the Documentation tool window, click the Show Options Menu icon on the tool window toolbar and disable the Show Documentation Popup First option.

Keep documentation in the tool window

You can open a piece of documentation for a specific code element in the tool window and keep viewing documentation for other elements in your current file.

  1. Place the caret at the required code element and press Ctrl+Q. If the popup appears, press Ctrl+Q again to switch to the tool window.

    The asterisk symbol (*) on the documentation tab means that the tab is not pinned, so its content will be replaced by documentation for another code element that you select in the editor.

  2. Right-click the tab with the documentation or click the Show Options Menu icon on the tool window toolbar and enable the Keep This Documentation option.

    After that, the current documentation tab will be pinned while you can return to the editor and browse through documentation for other code elements that will open either in the popup or in a new tab in the tool window.

When you are viewing code documentation in the tool window, it is displayed on the unpinned tab (the tab marked with the asterisk symbol (*). There are several ways in which you can work with it:

Type Info

In DataGrip, you can identify the type of an expression in the following way:

  • Place the caret at the necessary code element and press Ctrl+Shift+P (or select View | Type Info from the main menu).
