Code Style

Scheme

In this area, choose the code style scheme and change it as required. Code style scheme settings are automatically applied every time JetBrains Rider generates, refactors, or reformats your code.

The IDE comes with two pre-defined schemes: the Project scheme and the Default scheme.

In the Project scheme, the settings that you configure apply only to your current project.
These settings are stored in the codeStyles folder under .idea and are shared through VCS together with the project.
The IDE creates the folder after you modify code style settings for your project.
In the Default scheme (IDE-level scheme), the settings that you configure apply to all existing projects that have the Default code style scheme selected.
These settings are stored in the codestyles folder under the JetBrains Rider configuration directory and are not shared through VCS.

If you want to use the project code style scheme as your default scheme, you can copy it to the IDE level. The other way around is also possible: you can overwrite your current project settings with the settings from an IDE-level scheme and share them with other members of your team.


Scheme	From this 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 list of commands to manage the schemes: Copy to IDE…: select this option to copy the scheme settings to JetBrains Rider. The option is available only for the Project scheme. Export: select this option to export the selected scheme to an .xml file or an .editorconfig file in the selected location. The option is available for the Project and IDE schemes. Import Scheme: select this option to import the scheme of the selected type from the specified location. The option is available for the Project and IDE schemes. Copy to Project…: select this option to overwrite your current project code style settings with the settings from the selected IDE code style scheme. The option is available only for IDE schemes. Duplicate…: select this option to create a copy of the selected scheme. The option is available only for IDE schemes. Reset: select this option to reset the default or bundled color scheme to the initial defaults shipped with JetBrains Rider. This command becomes available only if some changes have been done. The option is available only for IDE schemes. Rename: select this option to change the name of the selected custom scheme. Press `Enter` to save changes, or `Escape` to cancel. The option is available only for IDE schemes.

Line Separators

JetBrains Rider lets you configure line separator and indentation options for various languages. When reformatting source code, JetBrains Rider will apply the specified indentation behavior and skip the sections denoted with the special formatting off/on markers.


Line Separator	Use this list to specify which line separator is to be used in files created by JetBrains Rider. The available options are: System-Dependent: select this option to use the default selection. Unix and macOS (\n): select this option to use the Unix and macOS line separator. Windows (\r\n): select this option to use the Windows line separator. Classic Mac OS (\r): select this option to use the `\r` line separator, which was used in Classic Mac OS (up to Mac OS 9).
Hard wrap at	In this field, specify the number of columns to be used to display pages in the editor.
Wrap on typing	Select this checkbox to ensure that edited text always fits in the specified right margin.
Visual guides	In this field, 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.

Indents detection

Use this area to specify the default options for indentation.


Detect and use existing file indents for editing	Select this checkbox for JetBrains Rider to detect the indentation style in the current file and use this style instead of the indents specified in the Code Style settings for the specific language.

EditorConfig

Select the Enable EditorConfig support checkbox to use EditorConfig for code style. In this case you can specify code style settings that override the IDE settings and have different code styles within a project.

If you decide to use IDE settings after creating the EditorConfig settings file then you need clear the Enable EditorConfig support checkbox.

Formatter

In this area, specify the markers to limit code fragments that you want to exclude from reformatting. In the source code, formatting markers are written inside line comments.


Do not format	In this field, specify a glob pattern with the names of files and directories that you want to exclude from reformatting, code arrangement, and import optimization.
Markers
Turn formatter on/off with markers in code comments	If this option is enabled, fragments of code between line comments with the formatting markers will not be reformatted and will preserve the original formatting. After you select this checkbox, the fields below become available and you can specify the character strings to be treated as formatting markers. If this option is disabled, the formatting markers will be ignored and the code between the line comments with markers will be reformatted.
Off:	In this field, 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`.
On:	In this field, 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`.
Enable regular expressions in formatter markers	Select this checkbox to use regular expressions instead of specifying the formatting markers explicitly. JetBrains Rider matches formatter on/off markers using the regular expression specified instead of the exact string.
