Scheme

In this area, choose the code style scheme and change it as required. Code style scheme settings are automatically applied every time CLion generates, refactors, or reformats your code.

Code styles are defined at the project level and at the IDE level (global).

  • At the Project level, settings are grouped under the Project scheme, which is predefined and is marked in bold. The Project style scheme is applied to the current project only.

    You can copy the Project scheme to the IDE level, using the Copy to IDE... command.

  • At the IDE level, settings are grouped under the predefined Default scheme (marked in bold), and any other scheme created by the user by the Duplicate command (marked as plain text). Global settings are used when the user doesn't want to keep code style settings with the project and share them.

    You can copy the IDE scheme to the current project, using the Copy to Project... command.

Description

Scheme

From this drop-down list, select the scheme to be used. The predefined schemes are shown bold. The custom schemes, ones created as copies of the predefined schemes, are in plain text. The location where the scheme is stored is written next to each scheme, for example, the Default scheme is stored in the IDE, the Project scheme is stored in the project.

Custom schemes

Line Separators

CLion lets you configure line separator and indentation options for various languages. When reformatting source code, CLion will apply the specified indentation behavior and skip the sections denoted with the special formatting off/on markers.

Item

Description

Line Separator (for new files)

Use this drop-down list to specify which line separator is to be used in files created by CLion. The available options are:
  • System dependent - choose this option to use the default selection.

  • Unix and macOS (\n) - choose this option to use the Unix and macOS line separator.

  • Windows (\r\n) - choose this option to use the Windows line separator.

  • Classic Mac (\r) - choose this option to use the Classic Mac line separator.

Hard wrap at

In this text box, specify the number of columns to be used to display pages in the editor.

Wrap on typing

Select this checkbox to ensure that edited text always fits in the specified right margin.

Visual guides

In this field, 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.

Default Indent Options

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, CLion uses spaces instead of tabs.

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 checkbox is selected) to be inserted for each indent level.

Keep indents on empty lines

Use this checkbox to keep the same indentation on empty lines as on lines containing code when the Reformat Code command is used.

Detect and use existing file indents for editing

Use this checkbox to detect code style settings in the currently edited file on the fly. In this case, when you open a file in the editor, indentation that was used in that file is preserved automatically. For example, if tabs were used for the indentation then in copy, paste or enter actions, tabs are used. Also, note that if you use the Reformat Code command then CLion applies default code style settings and uses them in the editor.

Formatter Control

In this area, specify the markers to limit code fragments that you want to exclude from reformatting. In the source code, formatting markers are written inside line comments.

Item

Description

Enable formatter markers in comments

  • If this checkbox is selected, fragments of code between line comments with the formatting markers will not be reformatted and will preserve the original formatting. After you select this checkbox, the fields below become available and you can specify the character strings to be treated as formatting markers.

  • If the checkbox is cleared, the formatting markers will be ignored and the code between the line comments with markers will be reformatted.

Markers

Formatter off:

In this text box, specify the character string that will indicate the beginning of a code fragment which you want to exclude from reformatting. Type a character string with the @ symbol in preposition or leave the predefined value @formatter:off.

Formatter on:

In this text box, specify the character string that will indicate the end of a code fragment which you want to exclude from reformatting. Type a character string with the @ symbol in preposition or leave the predefined value @formatter:on.

Regular expressions

Select this checkbox to use regular expressions instead of specifying the formatting markers explicitly. CLion matches formatter on/off markers using the regular expression specified instead of the exact string.
