Code Style. ActionScript

Use this page to configure formatting options for ActionScript files. When you change these settings, the Preview pane shows how this will affect your code.

Tabs and Indents

Item	Description
Use tab character	If this checkbox is selected, tab characters are used: On pressing the `Tab` key For indentation For code reformatting When the checkbox is cleared, IntelliJ IDEA uses spaces instead of tabs.
Smart tabs	If this checkbox is selected, the part of indentation defined by the nesting of code blocks, is made of the tabs and (if necessary) spaces, while the part of indentation defined by the alignment is made only of spaces. If this checkbox 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 checkbox is available if the Use tab character checkbox is selected.
Tab size	In this field, specify the number of spaces included in a tab.
Indent	In this field, specify the number of spaces to be inserted for each indent level.
Continuation indent	In this field, specify the number of spaces to be inserted between the elements of an array, in expressions, method declarations and method calls.

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 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 the preview.

Alignment takes precedence over indentation options.

Hard wrap at

Use the Hard wrap at field to specify a margin space required on the right side of an element. If you select the 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:

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.

Visual guides

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.

Wrapping options

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

Item	Description
Wrapping style	From this 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.

Braces placement options

Item Description

Braces placement style

Item	Description
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: End of line: select this option to have the opening brace placed at the declaration line end.

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 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 statement occupies more than one line. Note that IntelliJ IDEA analyzes the number of lines in the entire statement but not only its condition. IntelliJ IDEA will insert braces automatically: Always: select this checkbox to have braces always introduced automatically.

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. : use this button to add a rule. The empty rule area opens. : use this button to remove the rule from the list. : use this button to edit an existing rule. To see this button, navigate to the rule that you want to edit and click the button. In popup that opens, modify the rule fields. : use these buttons to move the selected rule up or down.
Empty rule	Use this area 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. Note that clicking a type keyword twice negates the condition. Modifier: use this filter to select the types of modifiers for the rule. Note that clicking a modifier keyword twice negates the condition. 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 so on. The filter supports regular expressions and uses a standard syntax. The match is performed against the entire name. Order: use this list 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. Aliases: this option displays aliases that were defined in the Rules Alias Definition dialog. You can remove the ones you do not need.
	This icon appears when you select Order by Name from the Order list. The icon indicates that the items in this rule are sorted alphabetically.
