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.
If this check box is selected, the part of indentation defined by the nesting of code blocks, is made of the tabs and (if necessary) spaces, while the part of indentation defined by the alignment is made only of 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.
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.
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 selected, then CLion will keep indents on the empty lines as if they contained some code. If this check box is not selected, CLion will delete the tab characters and 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.
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.
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.
From the drop-down list, select the type of dict alignment:
Do not align: the dict's elements in sequential lines will be not aligned.
Align on colon: the dict's elements in sequential lines will be aligned against the colon.
Align on value: the dict's elements in sequential lines will be aligned against the value.
Add line feed at the end of file
Select this check box to add line feed character at the end of file.
Use continuation indent for arguments
Select this check box to use continuation indent (defined in the Tabs and Indents tab) for list of arguments. If this check box is not selected, then the indent value is used.
