DataGrip 2020.2 Help

Search for usages

When you write or edit code, you might come across a code element that you want to change or delete. Before you make the changes, it is a good practice to see where the code element is used and how it affects the application. With the Find Usages actions you can search for the references of your code element throughout the whole codebase.

You can manage the search process, and search only in a single file, extend your search to the whole project, or create a certain search scope. Moreover, you can configure the color of the usages highlighting or disable the automatic highlighting of usages altogether.

Search for usages in a file

  1. In the editor, select a symbol you want to find, DataGrip automatically highlights all found usages in the file. If the highlighting of usages is disabled, press Ctrl+Shift+F7 to highlight all usages in the file.

  2. From the main menu, select Edit | Find Usages | Find Usages in File Ctrl+F7. DataGrip selects the first usage occurrence in the file.

    Use the F3 and Shift+F3 shortcuts to navigate between highlighted symbols.

Search for usages in a project

  1. Select a symbol for which you want to find usages, right-click the symbol, and select Find Usages from its context menu or press Alt+F7.

  2. Check the results in the Find tool window.

    If you need, you can group (the Group By icon) the results by files, packages, directories, and so on.

    To open the Find Usages dialog, click Settings icon on the toolbar in the Find tool window or press Ctrl+Alt+Shift+F7.

Show usages in a separate window

You can view usages of the selected symbol in a separate window that you can move to different parts of your screen and use for quick navigation.

  1. In the editor, select a symbol for which you want to see the usages.

  2. From the main menu, select Edit | Find Usages | Show Usages Ctrl+Alt+F7.

    The usages window shows the current scope and total count of usages. If you want to quickly switch to the default scope, press Ctrl+Alt+F7.

    If the search results have too many entries, then DataGrip shows the first hundred usages found and the more usages option on the bottom of the window which you can click to display another hundred usages, and so on until the search is finished.

    Use filters on the top of the window to show or hide the certain search entries.

View recent usages search results

DataGrip remembers your Find Usages results, so you don't need to run the action again.

  • From the main menu, select Edit | Find | Recent Find Usages and then select the usage query.

Manage the Find Usages scope

Sometimes, you might want to find usages only in certain files or libraries of your project.

  1. Press Ctrl+Alt+Shift+F7 to open the Find Usages dialog.

  2. In the Find Usages dialog, in the Scope field, select a scope for your search. For example, you can search for usages only in Open Files or only Recently Changed Files.

    You can also set a custom scope by clicking the ellipsis icon. For example, you can create a custom scope to exclude certain files from the search for usages, such as test files. When you are done setting a new scope, click Find.

  3. If DataGrip doesn't return any results, it will display a message suggesting that you opt for more options.

    No usages found popup

    You can follow the link or press Ctrl+Alt+Shift+F7 to open the Find Usages dialog again and set a new scope for your search.

Disable automatic highlighting of usages

When you place the caret at a symbol, the IDE highlights all usages of this symbol in the current file.

If necessary, you can disable the automatic highlighting.

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

  2. Clear the Highlight usages of element at caret checkbox.

When automatic highlighting is disabled, and you want to highlight usages of a symbol in the current file, select this symbol and press Ctrl+Shift+F7. This will highlight all usages of the symbol in the current file.

Change the background color of the highlighted usages

  1. In the Settings/Preferences dialog Ctrl+Alt+S, go to Editor | Color Scheme | General.

  2. From the options on the right, open the Code node and select Identifier under caret.

  3. In the Background field, specify the color you need and save the changes.

Search for the base method or method's implementations

When you search for usages of a method, DataGrip prompts you to choose whether you want to search for the base method or method's implementations.

If you select the Remember, don't ask again checkbox, DataGrip will no longer display the prompt, and the selected search option will be used as default. If necessary, you can restore the prompt.

  1. In the Settings/Preferences dialog Ctrl+Alt+S, go to Editor | General | Smart Keys.

  2. In the PHP area, select the Show additional options when searching for method usages checkbox.
