Code Style. Swift
Use this page to configure code style options for Swift files. When you change these settings, the Preview pane shows how this will affect your code.
Click this link to reveal the list of languages to be used as the base for the current language code style. Only the settings that are applicable to the current language are taken. All the other settings are not affected.
Click Reset to discard changes and return to the initial set of code style settings.
Tabs and Indents
Use tab character
The Smart tabs checkbox is available if the Use tab character checkbox is selected.
In this field, specify the number of spaces included in a tab.
In this field, specify the number of spaces to be inserted for each indent level.
In this field, specify the number of spaces to be inserted between the elements of an array, in expressions, method declarations and method calls.
Keep indents on empty lines
If this checkbox is selected, CLion will keep indents on the empty lines as if they contained some code.
If this checkbox is cleared, CLion will delete the tab characters and spaces.
Chained method indent
In this field, specify the number of spaces to be inserted before each chained method call. You can set up the chained method indentation style in.
Indent multiline strings
If this checkbox is selected, the multiline strings will be indented.
Follow code indent: if the checkbox is selected, conditional compilation blocks will be indented to match the surrounding code.
Indent children: if the checkbox is selected, the statements within conditional compilation blocks will be indented.
The option is available when the Follow code indent is selected.
Use this tab to specify where you want spaces in your code. To have CLion automatically insert a space at a location, select the checkbox 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, and so on) The right-hand pane shows the preview.
Alignment takes precedence over indentation options.
Hard wrap at
Use the Hard wrap at field to specify a margin space required on the right side of an element. If you select the Default option, then a value of the right margin from the global settings is used.
Wrap on typing
Use the Wrap on typing settings to specify how the edited text is fitted in the specified Hard wrap at:
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.
Use the Visual guides field to 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.
Keep when reformatting
Use the checkboxes to configure exceptions that CLion will make when reformatting the source code. For example, by default, the Line breaks checkbox is selected. If your code contains lines that are shorter than a standard convention, you can convert them by disabling the Line breaks checkbox before you reformat the source code.
Align when multiline
If this checkbox 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 checkbox 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 checkbox to have the corresponding statements or characters moved to the next line.
Special 'else if' treatment
If this checkbox is selected,
Indent 'case' branches
If this checkbox is selected, the
Braces placement options
Braces placement style
Use this list to specify the position of the opening brace in class declarations, function declarations and other types of declarations. The available options are:
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 this area, specify the number of blank lines to be present in the specified locations.
