Scheme

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

The 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 bold. The Project style scheme applies to the current project only.

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

  • At the IDE level, settings are grouped under the predefined Default scheme (marked bold), and any other scheme created by the user by the command Dulpicate (marked plain text). The 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 command Copy to Project.... So doing, the following dialog box appears:

    /help/img/idea/2017.1/overwrite_settings.png

    Clicking Yes results in overwring the project code style settings, clicking No cancels the operation.

ItemDescription
SchemeFrom 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. Next to each scheme it is written where the scheme is stored, for example, the Default scheme is stored in the IDE, the Project scheme is stored with the project.

Default Indent Options

ItemDescription
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, CLion uses spaces instead of tabs.
Tab sizeIn this text box, specify the number of spaces included in a tab.
IndentIn 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.
Keep indents on empty linesUse this check box 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 editingUse this check box 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, see more in Reformatting Source Code. In the source code, formatting markers are written inside line comments, see Commenting and Uncommenting Blocks of Code.

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