Code Style

Scheme

From this 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.

Click this button to invoke the list of commands to manage the schemes:

• Copy to IDE: select this option to copy the scheme settings to CLion.

  tip

  The option is available only for the Project scheme.

• Export: select this option to export the selected scheme in the IntelliJ IDEA code style XML or .clang-format File format (if the CLang Format plugin is enabled).

  tip

  The option is available for the Project and IDE schemes.

• Import Scheme: select this option to import the scheme of the selected type from the specified location.

  tip

  The option is available for the Project and IDE schemes.

• Copy to Project: select this option to overwrite your current project code style settings with the settings from the selected IDE code style scheme.

  tip

  The option is available only for IDE schemes.

• Duplicate: select this option to create a copy of the selected scheme.

  tip

  The option is available only for IDE schemes.

• Reset: select this option to reset the default or bundled color scheme to the initial defaults shipped with CLion. This command becomes available only if some changes have been done.

  tip

  The option is available only for IDE schemes.

• Rename: select this option to change the name of the selected custom scheme. Press Enter to save changes, or Escape to cancel.

  tip

  The option is available only for IDE schemes.

Line Separator

Use this list to specify which line separator is to be used in files created by CLion. The available options are:

• System-Dependent: select this option to use the default selection.

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

• Windows (\r\n): select this option to use the Windows line separator.

• Classic Mac OS (\r): select this option to use the \r line separator, which was used in Classic Mac OS (up to Mac OS 9).

Hard wrap at

In this field, 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.

Enable ClangFormat with clangd server

Select this checkbox to turn on ClangFormat as alternative code formatter (ClangFormat settings override the IDE code style settings). Note that ClangFormat requires the Clangd language engine to be enabled.

Do not format

In this field, specify a glob pattern with the names of files and directories that you want to exclude from reformatting, code arrangement, and import optimization.

Turn formatter on/off with markers in code comments

• If this option is enabled, fragments of code between line comments with the formatting markers will be reformatted according to these markers: code fragments with on-markers will be reformatted, and the fragments with off-markers will remain intact after you reformat your code. See Example of using formatting markers.

  After you select this checkbox, the fields below become available, and you can specify the character strings to be treated as formatting markers.

• If this option is disabled, the formatting markers will be ignored and the code between the line comments with markers will be reformatted.

Off:

In this field, 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.

On:

In this field, 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.

Enable regular expressions in formatter markers

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.

For example, using regular expressions allows you to have several markers for enabling the formatter and for disabling it. In that case, you can use the following regular expressions: @formatter:(off|disable|no) and @formatter:(on|enable|yes).
