Write and edit source code
When you work with code, DataGrip ensures that your work is stress-free. It offers various shortcuts and features to help you add, select, copy, move, edit, fold, find occurrences, and save code.
For navigation inside the editor, refer to Editor basics.
If you do not remember a shortcut for the action you want to use, press Ctrl+Shift+A to find any action by name.
You can use the same dialog to find classes, files, or symbols. For more information, refer to Searching Everywhere.
Add a new file or a scratch file
In the Files tool window ( ), press Ctrl+Alt+Insert to add a file.
To create a new Scratch file, press Ctrl+Alt+Shift+Insert.
DataGrip creates a temporary file that you can run and debug. For more information, refer to Scratch files.
Toggle read-only attribute of a file
If a file is read-only, it is marked with the closed lock icon in the status bar, in its editor tab, or in the Project tool window. If a file is writable, it is marked with the open lock icon in the Status bar.
Open file in the editor or select it in the Project tool window.
Do one of the following:
From the main menu, select, or .
Click the lock icon in the status bar.
If a read-only status is set by a version control system, it's suggested that you use DataGrip version control integration features. For more information, see Version control.
Select code constructs
In the editor, place the caret at the item you want to select and press Ctrl+W/ Ctrl+Shift+W to extend or shrink your selection.
For example, in a plain text file, the selection starts within the whole word then extends to the sentence, paragraph, and so on.
If you need just to highlight your braces, place the caret immediately after the block closing brace/bracket or before the block opening brace/bracket.
You can quickly locate all occurrences of the selected element in a file, make a multiple selection, or select the next or the previous occurrences.
To make a multiple selection of occurrences in a file, select the needed element in your code, then press Alt+J. Press the same key to find the next occurrence.
Alternatively, keeping Shift+Alt pressed, double-click or drag over the text you want to add to the selection.
- To move the caret to the next or the previous occurrence, press F3 or Shift+F3 respectively.
When you pressF3, DataGrip automatically removes the selection of the current occurrence and selects the next one.
To select all occurrences in the file, press Ctrl+Alt+Shift+J.
To find the next or the previous occurrence of the selected identifier, press Alt+Wheel up or Alt+Wheel down.
Configure tabs and indents
In the Settings/Preferences dialog Ctrl+Alt+S , go to .
Select a language for which you want to configure the indentation.
From the options on the right, on the Tabs and Indents, select the Use tab character for the editor to use tabs when you press Tab, indent, or reformat code. You can also configure the tab size if you need. If you don't select this option, DataGrip will use spaces.
Copy and paste code
You can use the standard shortcuts to copy Ctrl+C and paste Ctrl+V any selected code fragment. If nothing is selected, DataGrip automatically copies the whole line where the caret is located.
By default, when you paste anything in the editor, DataGrip performs "smart" paste, for example, pasting multiple lines in comments will automatically add the appropriate markers to the lines you are pasting. If you need to paste just plain text, press Ctrl+Alt+Shift+V.
Place the caret at a line or a symbol and press Ctrl+Alt+Shift+C/Ctrl+V.
- DataGrip keeps track of everything you copy to the clipboard. To paste from history, press Ctrl+Shift+V. In the dialog that opens, select your entry and click Paste.
Lines of code
DataGrip offers several useful shortcuts for manipulating code lines.
To add a line after the current one, press Shift+Enter. DataGrip moves the caret to the next line.
To add a line before the current one, press Ctrl+Alt+Enter. DataGrip moves the caret to the previous line.
To duplicate a line, press Ctrl+D.
To sort lines alphabetically in the whole file or in a code selection, from the main menu, select Keyboard shortcuts for more information.or . These actions might be helpful when you work with property files, data sets, text files, log files, and so on. If you need to assign shortcuts to those actions, refer to
To delete a line, place the caret at the line you need and press Ctrl+Y.
To join lines, place the caret at the line to which you want to join the other lines and press Ctrl+Shift+J. Keep pressing the keys until all the needed elements are joined.
You can also join string literals, a field or variable declaration, and a statement. Note that DataGrip checks the code style settings and eliminates unwanted spaces and redundant characters.
To split string literals into two parts, press Enter.
DataGrip splits the string and provides the correct syntax. You can also use the Break string on '\n' intention to split string literals. Press Alt+Enter or click to select this intention.
To comment a line of code, place the caret at the appropriate line and press Ctrl+/.
To move a line up or down, press Alt+Shift+Up or Alt+Shift+Down respectively.
In the editor, place the caret at the needed statement and press Ctrl+Shift+Up to move a statement up or Ctrl+Shift+Down to move a statement down. DataGrip moves the selected statement performing a syntax check.
Complete current statement
In the editor, press Ctrl+Shift+Enter or from the main menu select. DataGrip inserts the required trailing comma automatically in structs, slices, and other composite literals. The caret is moved to the position where you can start typing the next statement.
Move and copy code fragments by dragging them in the editor.
To move a code fragment, select it and drag the selection to the target location.
To copy a code selection, keeping Ctrl pressed, drag it to the target location.
The drag functionality is enabled by default. To disable it, in the Settings/Preferences dialog Ctrl+Alt+S, go to and clear the Enable Drag'n'Drop functionality in editor checkbox in the Mouse section.
To toggle between the upper and lower case for the selected code fragment, press Ctrl+Shift+U.
Note that when you apply the toggle case action to the CamelCase name format, DataGrip converts the name to the lower case.
To comment or uncomment a code fragment, select it and press Ctrl+Shift+/.
To configure settings for commenting behavior, use options in the Comment Code section, on the Code Generation tab located in the language-specific pages under .
You can edit multiple lines simultaneously. For example, you can add comment markers to multiple lines, or remove some characters in several occurrences of a word.
To add or remove multiple carets, press and hold Shift+Alt and click at the next location of the caret.
Alternatively, to add multiple carets, you can press Ctrl twice, and then without releasing it, press the Up or Down arrow keys. You can also make a multiple selection by pressing Shift+Alt and dragging the caret.
To delete all added carets, press Escape.
You can make a multiple selection of code in columns. To enable or disable the column selection mode, press Alt+Shift+Insert or use the context menu of the editor.
This mode is helpful when you want to edit several lines of code simultaneously. Place the caret at a symbol you need and either drag it up or down, or select a block of code and press the specified shortcut to achieve the same result.
You can change the behavior of the caret move when you press Alt+↑/↓. The default behavior is to move the caret to the end of the current word. To change this setting, open settings Ctrl+Alt+S and navigate to Caret Movement section, select an appropriate behavior from the list.. In the
Parameter hints show the names of parameters in methods and functions to make your code easier to read. By default, parameter hints are enabled and shown only for values that are literals or function expressions but not for named objects.
Configure parameter hints
Open the Settings/Preferences dialog Ctrl+Alt+S and go to .
Select Parameter hints from the list, make sure the Show parameter hints checkbox is selected, and then specify the context where you want parameter hints shown.
