Tabs and indents

Item Description
Use tab character
  • If this check box is selected, tab characters are used:
    • On pressing the TabTabTabTabTabTabTabTabTabTabTabTab 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, but fine alignment to a necessary column is done only via spaces without replacing them with tabs. This is done in order to preserve visual representation of the source code, when the Tab Size is changed.
  • 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 at the next line in case of a construct break.

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.

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.

Note

Alignment takes precedence over indentation options.

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 brakes check box is selected. If your code contains lines that are shorter than a standard convention, you can convert them by disabling the Line brakes 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.

    Note

    If this option is 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.
  • 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.
  • Wrap always - select this option to have all elements in lists wrapped so that there is one element per line with proper indentation.

Alignment options

Item Description
<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.
New line after <character> Select this check box to have the code after the specified character moved to a new line.
Place on new line Use this check box to have the corresponding statements or characters moved to the next line.
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.
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.

Braces placement options

Item Description
Braces placement style Use this drop-down list to specify the position of the opening brace in class declarations, method declarations, and other types of declarations. The available options are:
  • End of line - select this option to have the opening brace placed at the declaration line end.
  • Next line if wrapped - select this option to have the opening brace placed at the beginning of the line after the multiline declaration line.
  • Next line - select this option to have the opening brace placed at the beginning of the line after the declaration line.
  • Next line shifted - select this option to have the opening brace placed at the line after the declaration line being shifted to the corresponding indent level.
  • Next line each shifted - select this option to have the opening brace placed at the line after the declaration line being shifted to the corresponding indent level, and have the next line shifted to the next indent level as well.
Force braces From this drop-down list, choose the braces introduction method for if, for, while, and do () while statements. The available options are:
  • Do not force - select this option to suppress introducing braces automatically.
  • When multiline - select this option to have braces introduced automatically, if a code construct occupies more than one line.
  • Always - select this check box to have braces always introduced automatically.

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.
Minimum Blank Lines In the text boxes in this area, specify the number of blank lines to be present in the specified locations.

Warning

These settings do not influence the number of blank lines before the first and after the last item.

Other

Item Description
Indent package statement children Select this check box to have the nested statements of package statements indented on code reformatting.
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.
Field prefix In this text box, specify the prefix to be used in ActionScript fields.
Property prefix In this text box, specify the prefix to be used in ActionScript properties.
Use semicolon to terminate statements Select this check box to have statements terminated with a semicolon.
Spaces before type reference colon ':' Select this check box to separate type reference with the space before colon.
Spaces after type reference colon ':' Select this check box to separate type reference with the space after colon.

Arrangement

This tab lets you define a set of rules that rearranges your code according to your preferences.

Item Description
Grouping Rules Use this area to set the grouping rules.
  • Group property field with corresponding getter/setter
Matching rules Use this area to define elements order as a list of rules, where every rule has a set of matches such as modifier or type.
  • add - use this button to add a rule. The empty rule dialog window opens.
  • delete - use this button to remove the rule from the list.
  • edit1 - use this button to edit an existing rule. To see this button, navigate to the rule that you want to edit and click on the button. In pop-up window that opens, modify the rule fields.
  • arrowUp arrowDown - use these buttons to move the selected rule up or down.
Empty rule Use this window to create a new matching rule or edit an existing one. You can select from the following filters:
  • Type - use this filter to choose classes or methods for your rule.
  • Modifier - use this filter to select the types of modifiers for the rule.
  • Name - use this field to specify entry names in the rule. This filter matches only entry names such as field names, method names, class names and etc. The filter supports regular expressions and uses a standard syntax. The match is performed against the entire name.
  • Order - use this option to select the sorting order for the rule. This option is useful when more than one element uses the same matching rule. In this case, selecting Keep order will keep the same order as was set before the rearrangement and selecting Order by Name will sort the elements with the same matching rule by their names.
icon_sort This icon appears when you select Order by Name in Order option. The icon indicates that the items in this rule are alphabetized.
