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.
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.
Click this button to invoke the drop-down list of commands to manage the schemes:
Copy to IDE...
Choose this command to copy the scheme settings to the IDE.
Choose this command to export the selected scheme to an xml file in the selected location:
Project and IDE
Choose this command to import the scheme of the selected type from the specified location:
Project and IDE
Copy to Project...
Choose this command to copy the scheme settings to be stored with a project.
Choose this command to create a copy of the selected scheme.
Choose this command 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.
Choose this command to change the name of the selected custom scheme. Press Enter to save changes, or Escape to cancel.
Default Indent Options
Use tab character
If this check box is selected, tab characters are used:
On pressing the Tab key
For code reformatting
When the check box is cleared, CLion uses spaces instead of tabs.
In this text box, specify the number of spaces included in a tab.
In 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 lines
Use 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 editing
Use 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.
If this check box 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 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.
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.
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.
Select 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.
