Tabs and Indents
| Item | Description |
|---|
| 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.
|
| Smart tabs |
-
If this check box is selected, CLion inserts tabs for indentation and reformatting.
CLion inserts tabs in the beginning of each line
until a symbol other than the tab is inserted. After that when you press the tab key,
CLion will enter spaces.
-
If this check box 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 check box is available if the
Use Tab Character check box is selected.
|
| 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
check box is selected) to be inserted for each indent level.
|
| Continuation indent | In this text box, specify the number of spaces (or tabs if the
Use Tab Character check box is selected) to be inserted between the elements
of an array, in expressions, method declarations and method calls. |
| Keep indents on empty lines | If this check box is cleared, then CLion will keep indents on the empty lines as if they have contained some code.
If this check box is not selected, CLion will delete the tabulation characters. |
Spaces
Use this tab to specify where you want spaces in your code. To have CLion automatically insert a space at a location,
select the check box next to this location in the list.
The results are displayed in the Preview pane.
Wrapping and Braces
In this tab, customize the code style options, which CLion will apply on reformatting the source code.
The left-hand pane contains the list of exceptions (Keep when reformatting), and
placement and alignment options for the various code constructs (lists, statements, operations, annotations, etc.).
The right-hand pane shows preview.
Alignment takes precedence over indentation options.
Right Margin (columns)
Use Right Margin field to specify a margin space required on the right side of an
element. If you select Default option then a value of the right margin from the
global settings is used.
Wrap on Typing
Use Wrap on typing settings to specify how the edited text is fitted in the
specified Right margin.
You can select one the following options:
- Default - in this case CLion uses the Wrap on typing option that is specified
in the global settings.
- Yes - in this case CLion uses the value specified in the
Right Margin field.
- No - in this case this option is switched off and a line can exceed
the value specified in the right margin.
Keep When Reformatting
Use the check boxes to configure exceptions that CLion will make when reformatting the source code.
For example, by default, the Line breaks check box is selected. If your code contains lines that are shorter than a
standard convention, you can convert them by disabling the Line breaks check box before you reformat the source code.
Alignment Options
| Item | Description |
|---|
|
Align when multiline |
If this check box is selected, a code construct starts at the same column on each next line.
Otherwise, the position of a code construct is determined by the current indentation level.
|
| Align parenthesised when multiline |
If this check box is selected, a parenthesised code construct starts at the column of the opening
parenthesis each next line. Otherwise, the position of a code construct is determined by the
current indentation level.
|
|
'else' on new line | Use this check box to have the corresponding statements or characters moved to the next line. |
| Special else if treatment | If this check box is selected, else if statements are located in the same line.
Otherwise, else if statements are moved to the next line to
the corresponding indent level.
|
| Indent case branches |
If this check box is selected, the case statement is located at the corresponding indent level.
Otherwise, case statement is placed at the same indent level with switch.
|
Braces Placement Options
| Item | Description |
|---|
|
Braces placement style
|
Use this drop-down list to specify the position of the opening brace in
class declarations,
function declarations
and other types of declarations. The available options are:
-

-
Next line if wrapped -
select this option to have the opening brace placed at the beginning of the line after
the multiline declaration line.
-
Next line -
select this option to have the opening brace placed at the beginning of the line after the
declaration line.
-
Next line shifted -
select this option to have the opening brace placed at the line after the declaration
line being shifted to the corresponding indent level.
-
Next line each shifted -
select this option to have the opening brace placed at the line after the declaration
line being shifted to the corresponding indent level,
and have the next line shifted to the next indent level as well.

Blank Lines
Use this tab to define where and how many blank lines you want CLion to retain and insert in your code
after reformatting. For each type of location, specify the number of blank lines to be inserted.
The results are displayed in the Preview pane.
| Item | Description |
|---|
| 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 the text boxes in this area, specify the number of blank lines to be present in the specified locations.
