Tabs and Indents

Item	Description
Use tab character	If this check box is selected, tab characters are used: On pressing the Tab key For indentation For code reformatting When the check box is cleared, IntelliJ IDEA uses spaces instead of tabs.
Smart tabs	If this check box is selected, IntelliJ IDEA inserts tabs for indentation and reformatting. IntelliJ IDEA inserts tabs in the beginning of each line until a symbol other than the tab is inserted. After that when you press the tab key, IntelliJ IDEA will enter spaces. If this check box is cleared, only tabs are used. This means that a group of spaces that fits the specified tab size is automatically replaced with a tab, which may result in breaking fine alignment. The Smart Tabs check box is available if the Use Tab Character check box is selected.
Tab size	In this text box, specify the number of spaces included in a tab.
Indent	In this text box, specify the number of spaces (or tabs if the Use Tab Character check box is selected) to be inserted for each indent level.
Continuation indent	In this text box, specify the number of spaces (or tabs if the Use Tab Character check box is selected) to be inserted between the elements of an array, in expressions, method declarations and method calls.
Keep indents on empty lines	If this check box is selected, then IntelliJ IDEA will keep indents on the empty lines as if they have contained some code. If this check box is not selected, IntelliJ IDEA will delete the tabulation characters.

Spaces

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 check box next to this location in the list. The results are displayed in the Preview pane.

Blank lines

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.

Item	Description
Keep Maximum Blank Lines	In this area, specify the number of blank lines to be kept after reformatting in the specified locations.
In code	Use this field to set the number of the blank lines.

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, etc.). The right-hand pane shows preview.

Alignment takes precedence over indentation options.

Right Margin (columns)

Use Right Margin 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 Wrap on typing settings to specify how the edited text is fitted in the specified Right margin. 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.

Keep When Reformatting

Use the check boxes to configure exceptions that IntelliJ IDEA will make when reformatting the source code. For example, by default, the Line breaks check box is selected. If your code contains lines that are shorter than a standard convention, you can convert them by disabling the Line breaks check box before you reformat the source code.

Wrapping Options

The wrapping style applies to the various code constructs, specified in the left-hand pane (for example, method call arguments, or assignment statements).

Item	Description
Wrapping style	From this drop-down list, select the desired wrapping style: Do not wrap - when this option is selected, no special wrapping style is applied. With this option selected, the nested alignment and braces settings are ignored. Wrap if long - select this option to have lines going beyond the right margin wrapped with proper indentation. Wrap always - select this option to have all elements in lists wrapped so that there is one element per line with proper indentation. Chop down if long - select this option to have elements in lists that go beyond the right margin wrapped so that there is one element per line with proper indentation.
Ensure right margin is not exceeded	If this check box is selected, the formatter will do its best to avoid having document lines exceeding the right margin. This option takes precedence over the Do not wrap wrapping style.

Alignment Options

Item	Description
Align when multiline	If this check box 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.
Align parenthesised when multiline	If this check box is selected, a parenthesised code construct starts at the column of the opening parenthesis each next line. Otherwise, the position of a code construct is determined by the current indentation level.
<character(s)> on next line	Select this check box to have the specified character or characters moved to the next line when the lines are wrapped.
'else' on new line	Use this check box to have the corresponding statements or characters moved to the next line.
New line after <character>	Select this check box to have the code after the specified character moved to a new line.
Special else if treatment	If this check box is selected, else if statements are located in the same line. Otherwise, else if statements are moved to the next line to the corresponding indent level.
Indent case branches	If this check box is selected, the case statement is located at the corresponding indent level. Otherwise, case statement is placed at the same indent level with switch.

Other

Item	Description
Align object properties	From the drop-down list, select the type of objects' alignment: Do not align: the attributes in sequential lines will be not aligned. On colon: the attributes in sequential lines will be aligned against the colon. On value: the attributes in sequential lines will be aligned against the value.
