Code Style. C/C++
Use this section to configure code style options for C/C++ files. When you change these settings, results of a change are displayed in the Preview pane.
Click this link to choose the base for the current language default code style from the list, that appears. The list contains the following options:
Choose this option to inherit the code style settings from another language. Select the source language from the list, that opens. So doing, only the settings that are applicable to the current language are taken. All the other settings are not affected.
|Predefined Style|| |
Choose this option to use one of the well-known code style guidelines. Select one of the following standards from the list.
Note: each code style affects only the certain items of base settings and leaves the rest unchanged.
The following styles are applicable for braces placement only:
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 (or tabs if the Use tab character checkbox 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 checkbox is selected, CLion will keep indents on the empty lines as if they contained some code.
In this field, specify the number of spaces (or tabs if the Use tab character checkbox is selected) to be inserted at the next line before a label statement.
Absolute label indent
If this checkbox is selected, label indentation is counted as an absolute number of spaces. Otherwise, label indentation is counted relative to previous indent levels.
Indent in lambdas
In this field, type the indent of lambda expressions.
Indent members of plain structures
In this field, type the indent of the plain structure members.
Indent members of classes
In this field, type the indent of the class members.
Indent visibility keywords in class/structure
In this field, type the indent of the visibility keywords (public, protected, etc).
Indent members of namespace
In this field, type the indent of members of namespaces.
Preprocessor directive indent
In this field type the indent of preprocessor directives.
Follow code indent
Select this checkbox to keep the indent of preprocessor directives equal to that of surrounding code lines.
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 preview.
Alignment takes precedence over indentation options.
Right Margin (columns)
Use the Hard wrap at 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 the Wrap on typing settings to specify how the edited text is fitted in the specified Hard wrap at. 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.
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:
From this list, choose the braces introduction method for
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.
Code Generation tab
New File Extensions TabIn this tab you can define the source/header file types used in the Create New C/C++ Source File dialog. This tab also determines the order of their appearance in the Type field of that dialog: the first pair in the tab is the first extension in the type list in dialog.
Source/header file types pane.
The list of source and header file types. All the code style rules specified under this node of Settings, are applicable to the listed file types.
From the drop-down list, choose the extension to be associated with the source files.
From the drop-down list, choose the extension to be associated with the header files.
File Naming Convention
Choose the preferred naming convention from the drop down list. This setting defines a case of the file name generated in the New C++ Class dialog when a new class is being created.
Click this button to add a new source/header file types pair to the list. The new pair is always of .cpp/.h type. When added to the list, assign the desired extensions from the Source Extension/Header Extension dropdown lists to them.
Click this button to remove the selected source/header file types pair from the list.
Alt+Up or Alt+Down
Use these buttons to move the selected source/header file types pair up and down in the list.
