Code Style. Groovy
Use this section to configure formatting options for Groovy files. When you change these settings, results of a change are displayed in the Preview pane.
Tabs and Indents
Use tab character
The Smart Tabs checkbox is available if the Use tab character checkbox is selected.
In this field, specify the number of spaces included in a tab.
In this field, specify the number of spaces (or tabs if the Use tab character checkbox is selected) to be inserted for each indent level.
Keep indents on empty lines
If this checkbox is selected, IntelliJ IDEA will keep indents on the empty lines as if they contained some code.
In this field, specify the number of spaces (or tabs if the Use tab character checkbox is selected) to be inserted at the next line before a label statement.
Absolute label indent
If this checkbox is selected, label indentation is counted as an absolute number of spaces. Otherwise, label indentation is counted relative to previous indent levels.
Use this tab to specify where you want spaces in your code. To have IntelliJ IDEA automatically insert a space at a location, select the checkbox next to this location in the list. The results are displayed in the Preview pane.
Wrapping and braces
In this tab, customize the code style options, which IntelliJ IDEA will apply on reformatting the source code. The left-hand pane contains the list of exceptions (Keep when reformatting), and placement and alignment options for the various code constructs (lists, statements, operations, annotations, and so on) The right-hand pane shows preview.
Alignment takes precedence over indentation options.
Right Margin (columns)
Use the Hard wrap at field to specify a margin space required on the right side of an element. If you select Default option then a value of the right margin from the global settings is used.
Wrap on typing
Use the Wrap on typing settings to specify how the edited text is fitted in the specified Hard wrap at. You can select one the following options:
Default: in this case IntelliJ IDEA uses the Wrap on typing option that is specified in the global settings.
Yes: in this case IntelliJ IDEA uses the value specified in the Right Margin field.
No: in this case this option is switched off and a line can exceed the value specified in the right margin.
Use the Visual guides field to specify multiple right margins. You can leave a default value or enter the number of spaces for your margin. If you want to specify several margins, enter numbers separated by comma.
Keep when reformatting
Use the checkboxes to configure exceptions that IntelliJ IDEA will make when reformatting the source code. For example, by default, the Line breaks checkbox is selected. If your code contains lines that are shorter than a standard convention, you can convert them by disabling the Line breaks checkbox before you reformat the source code.
The wrapping style applies to the various code constructs, specified in the left-hand pane (for example, method call arguments, or assignment statements).
From this list, select the desired wrapping style:
Align when multiline
If this checkbox is selected, a code construct starts at the same column on each next line. Otherwise, the position of a code construct is determined by the current indentation level.
Select this checkbox to have the specified character or characters moved to the next line when the lines are wrapped.
'else' on new line
Use this checkbox to have the corresponding statements or characters moved to the next line.
New line after
Select this checkbox to have the code after the specified character moved to a new line.
Special else if treatment
If this checkbox is selected,
Indent case branches
If this checkbox is selected, the

Braces placement style
Use this list to specify the position of the opening brace in class declarations, method declarations, and other types of declarations. The available options are:
From this list, choose the braces introduction method for
Use this tab to define where and how many blank lines you want IntelliJ IDEA to retain and insert in your code after reformatting. For each type of location, specify the number of blank lines to be inserted. The results are displayed in the Preview pane.
Keep Maximum Blank Lines
In this area, specify the number of blank lines to be kept after reformatting in the specified locations.
Minimum Blank Lines
In the text boxes in this area, specify the number of blank lines to be present in the specified locations.
This table lists actions to be performed when imports are optimized.
In this area, configure general import options.
JSP Imports Layout
In this area, configure how JSP import statements should be organized in your code. The introduced changes are displayed in the Preview pane below.
Packages to Use Import with '*'
In this area, configure a list of packages and classes to be always imported completely.
In this area, configure how import statements should be organized in your code. You can set up certain classes to be positioned first, or last, or one after another. Imported classes will be grouped as per their packages and sorted alphabetically within a package.
Order of Members
Use this area to configure a sorting hierarchy of your code members. You can move the list items up or down using or arrow keys.
Use this area to configure code style for generated comments. For example, you can use the default selected options to start the line and block comments at the first column. If you clear those options, the comments will be aligned in your code.
You can select Add a space at comment start option to insert a space between a line comment character and the first character of a commented line.
