Code Style. Groovy

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.

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.

If this checkbox is cleared, IntelliJ IDEA will delete the tab characters and spaces.

Label indent

In this field, specify the number of spaces 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.

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 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.

General

In this area, configure general import options.

Options:

• Use single class import: import only a particular class from a package during code generation or import optimization. Otherwise, a statement that imports an entire package is inserted.

• Use fully qualified class names: use the fully qualified name of the class to be imported during code generation or import optimization. Otherwise, a normal import statement is inserted.

• Insert imports for inner classes: create imports for the inner classes referenced in your code.

• Use fully qualified names in JavaDoc: use fully qualified class names in Javadocs. Otherwise, a class is imported.

• Class count to use import with '*': specify the number of classes to be imported from a single package until all statements that import a single class are substituted with a statement that imports an entire package.

• Names count to use static import with '*': in this field, specify the number of members to be imported from a single class until all statements that import a single member are substituted with a statement that imports an entire class.

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.

Options:

• Prefer comma separated import list: select this option to import statements organized in a comma separated list.

• Prefer one import statement per page directive: select this option to have one import statement created per line.

Packages to Use Import with '*'

In this area, configure a list of packages and classes to be always imported completely.

Options:

• Static: select this checkbox, if you want to declare static import for the selected class.

• Package: in the text fields of this column, specify the packages and classes to be always imported completely.

  Note that IntelliJ IDEA automatically adds .* at the end of the package name once you finish typing.

• With Subpackages: select this checkbox to have all the subpackages of the selected package imported completely.

• Add Package: click this button to add a new entry to the list of packages and classes.

• Add Blank: click this button to add an empty separator to the list of packages and classes.

• Remove: click this button to delete the selected package or class from the list.

Import Layout

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.

Options:

• Layout static imports separately: if this checkbox is selected, all static imports will be kept in a separate section. Otherwise, all import statements will be sorted according to the specified layout rules.

• Static: select this checkbox, if you want to declare static import for the selected package.

• Package: in the text fields of this column, specify the packages to be imported.

• With Subpackages: select this checkbox to have IntelliJ IDEA apply the layout rules to all the subpackages of the selected package.

• Add Package: click this button to add a new entry to the list of packages.

• Add Blank: click this button to have a blank line inserted after the selected entry, which indicates that a blank line should be inserted between the corresponding import statements.

• Move Up / Move Down: click these buttons to move a package or a blank line up or down in the list thus defining the order of import statements.

• Remove: click this button to delete the selected package from the list.

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.

Comment Code

Use this area to configure code style for generated comments (line Ctrl+/ and block Ctrl+Shift+/):

• Line comment at first column: start line comments (Ctrl+/) at the first column. If you disable the option, the comments will be aligned with your code.

• Add a space at comment start: insert a space between the line comment character and the first character of the commented line.

• Enforce on reformat: insert a space between a line comment character and the first character of a commented line in existing comments when you're reformatting your code. Note that the first character has to be an alphanumeric symbol, otherwise the space won't be inserted. For example, the //&Lorem ipsum comment will be ignored by the reformatter.

  This option becomes available when Add a space at comment start is enabled.

• Block comment at first column: start block comments (Ctrl+Shift+/) at the first column. If you disable the option, the comments will be aligned with your code.

• Add spaces around block comments: insert a space between the block comment character and the first character of the commented text.
