JetBrains Rider 2022.1 Help

Code Cleanup

This page of JetBrains Rider options allows you to manage and configure custom cleanup profiles, as well as to assign a cleanup profile for the silent code cleanup. The two default profiles (Full Cleanup, Reformat & Apply Syntax Style and Reformat Code) are also shown here. You cannot modify them, but you can clone them to make new custom profiles.

Toolbar controls

Use the following controls to configure the selected cleanup profile:

Themed icon add pattern screen gray Add

Click this button to create a new custom Code Cleanup profile. As soon as a new profile is created, it opens in the editing mode, where you can configure the list of cleanup tasks.

Themed icon code cleanup option page screen gray Set as default

Click this button to use the selected profile for silent cleanup.

Themed icon duplicate screen gray Clone

Click this button to create a copy of the selected profile. If you have default settings, you will need to duplicate one of the default cleanup profiles to create a custom cleanup profile. As soon as a new profile is created, it opens in the editing mode, where you can configure the list of cleanup tasks.

Themed icon edit screen gray Rename

Click this button to rename the selected custom profile. Note that default profiles (Full Cleanup, Reformat & Apply Syntax Style and Reformat Code) cannot be renamed.

Themed icon remove screen gray Remove

Click this button to remove the selected custom profile. Note that default profiles (Full Cleanup, Reformat & Apply Syntax Style and Reformat Code) cannot be removed.

Code cleanup tasks for selected profile

These tasks become configurable for the selected custom cleanup profile. Initially, there are no custom profiles and tasks of the default profiles cannot be edited. You can click App actions copy Clone to create an editable copy of one of the default profiles and then edit its tasks.

Remove redundancies & apply optimizations

C#

Remove code redundancies

On the Editor | Inspection Severity page of JetBrains Rider settings Ctrl+Alt+S, in the Redundancies in Code categories of most languages, JetBrains Rider lists dozens of cases that have associated code inspections. Some of them require special attention, and you cannot process them in the batch mode, but most of them can be fixed automatically whenever you select Remove code redundancies in your cleanup profile.

Use auto-property, if possible

Replaces simple properties and corresponding backing fields with auto-properties. For more information, see Use auto-properties.

Make field read-only, if possible

Adds the readonly keyword to fields that are assigned in the declaration or in a constructor and only have read usages. For more information, see Make fields readonly.

Make auto-property get-only, if possible

Removes the redundant set accessor on auto-properties that are initialized from the constructor/initializer and have no write usages.

By default, JetBrains Rider automatically detects C# version based on the associated compiler. However, you can specify the target C# version explicitly for a project — press Alt+Enter on the project in the Solution Explorer and use the Language version selector on the Application page of the Project Properties dialog .

To set the C# version for all projects in your solution, specify it in a Directory.Build.props file in your solution directory as described here.

Remove redundant elaborated type specifiers

Remove redundant lambda parameter lists

Remove redundant member initializers

Remove redundant parentheses

Remove redundant qualifiers

Remove redundant specifiers

Remove unreachable code

Remove unused #include directives

Remove unused lambda captures

Replace C-style and functional-style casts with static casts

Replace constants in boolean context with boolean literals

Replace if statements with constant conditions with 'if constexpr'

Replace postfix operators with prefix variants

Replace smart pointer constructors with make functions

Replace throw expressions with rethrow where possible

Replace type traits with corresponding template aliases or variable templates

Replace zero valued expressions in pointer context with nullptr

Replace 'tie(..)' with structured binding declarations

Use 'contains' for associative containers wherer possible

Use 'std::erase'/'std::eraseif' instead of remove-erase idiom

Visual Basic .NET

Remove code redundancies

On the Editor | Inspection Severity page of JetBrains Rider settings Ctrl+Alt+S, in the Redundancies in Code categories of most languages, JetBrains Rider lists dozens of cases that have associated code inspections.

Run external cleanup tools

C/C++

Apply Clang-tidy fix-its

In this node, you can choose all or specific fixes that will be applied according to the Clang-Tidy checks.

The selected fixes will be applied even if the corresponding inspections are turned off on the Editor | Inspection Settings| Inspection Severity page of JetBrains Rider settings Ctrl+Alt+S. Be careful when enabling too many checks at once — code cleanup runs Clang-Tidy only once for a given file, so if multiple fixes touch the same block of code, the changes might conflict with each other.
