ReSharper 2023.3 Help

Code cleanup

ReSharper allows you to apply formatting and other code style preferences in a bulk mode to instantly eliminate code style violations in one or more files, in a project or in the entire solution.

Code cleanup profiles

Code cleanup can have various configurations (profiles) to apply in different cases according to your needs. There are three default profiles available out of the box:

These profiles help in most cases but you cannot configure them. If you want to run code cleanup with the custom set of cleanup tasks, you need to create a custom profile and specify the set of desired tasks there.

Create a new custom cleanup profile

  1. Select ReSharper | Options from the main menu or press Alt+R O.

  2. Go to the cleanup profiles settings page: Code Editing | Code Cleanup | Profiles.

  3. Select one of the existing profiles on the left and click Duplicate on the top of the page. ReSharper will create a new cleanup profile with the same set of tasks as in original profile.

  4. Select the newly created profile in the list of profiles.

  5. Click Configure on the top of the page.

  6. The tasks of the selected profile become editable on the right. Configure them as desired.

  7. If you want to create or edit other profiles before saving your modifications, click Done on the top of the page to temporarily remember modifications to the current profile.

  8. Click Save in the Options dialog to apply the modifications and let ReSharper choose where to save them, or save the modifications to a specific settings layer by choosing this layer from the Save To selector. For more information, see manage and share resharper settings.

Your newly created cleanup profile will be available in the Code Cleanup dialog when you are running code cleanup. You can also set this profile to be used for the silent cleanup.

Run code cleanup

ReSharper can apply code cleanup to an arbitrarily selected block of code, all code in the current file, all files in a directory, the current project, or even the current solution. Make sure that you select the right set of cleanup tasks by choosing the right cleanup profile.

Clean up selection or file

  1. Select the scope where you want to clean up code:

    • Make a selection in the editor to clean up code in the selection.

    • Place the caret anywhere in the file to clean up code in the file.

  2. If you are cleaning up a selection, press Alt+Enter and choose Reformat and cleanup | [cleanup profile].

    Alternatively you can follow the below steps, which work for both selection and file.

  3. Do one of the following:

    • Press Control+Alt+F or choose ReSharper | Edit | Cleanup Code… from the main menu .

    • Right-click anywhere in the text editor or right-click the selection and choose Cleanup Code in the context menu.

  4. In the Code Cleanup dialog that opens, choose a cleanup profile to apply. Use the area to the right of the selected profile to check the tasks included in that profile.

  5. If none of the available profiles suits you, choose one of the existing profiles and click Duplicate to create a new custom profile.

    Note that if you create or modify cleanup profiles in this dialog, your changes will be saved using the smart save logic. If you need to save your modifications to a shared settings layer, make your modifications on the Code Editing | Code Cleanup page of ReSharper options, click Save To and then choose the desired settings layer.

    ReSharper. Code Cleanup dialog
  6. Click Run to clean up code in the selected scope.

  7. By default, files that are opened in the editor are not saved automatically after cleanup. If you want to enable auto-saving after cleanup, select Save after cleanup is applied to the whole file on the Code Editing | Code Cleanup | General page of ReSharper options ( Alt+R, O ).

You can clean up not only an individual file, but also multiple files in a directory, project or entire solution. To do so, run code cleanup from the Solution Explorer.

Clean up multiple files, projects, or entire solution

  1. Select one or more items (files, directories, projects, or the solution) in the Solution Explorer.

  2. Do one of the following:

    • Press Control+Alt+F or choose ReSharper | Edit | Cleanup Code… from the main menu .

    • Right-click the selection and choose Cleanup Code in the context menu.

  3. Choose a cleanup profile as described above.

  4. Click Run to clean up code in the selected scope.

You can run Code Cleanup every time you save changes in a file to make sure that your edits always comply with your code style.

Automatically run Code Cleanup on saving changes

  1. Select ReSharper | Options from the main menu or press Alt+R O.

  2. Go to the cleanup profiles settings page: Code Editing | Code Cleanup | Profiles.

  3. Select which Code Cleanup profile should be applied on save and click Set as default (the default profile is also used for silent cleanup).

  4. Go to the Code Editing | Code Cleanup | General options page and select Automatically run cleanup when saving a file.

    Optionally, you can restrict automatic cleanup to specific files by a file mask. You can also select Only changed parts of file to make sure that cleanup is applied to the code affected by your changes, and the rest of the code in the file is not modified.

  5. Click Save in the dialog to apply the modifications and let ReSharper choose where to save them, or save the modifications to a specific settings layer by choosing this layer from the Save To selector. For more information, see manage and share resharper settings.

  6. The next time you finish editing and save the file (Ctrl+S) or all files (Ctrl+Shift+S), ReSharper will clean up the affected files using the selected profile. If the default cleanup profile is not selected, ReSharper will prompt you choose one of the profiles.

You can also run code cleanup in files that you recently opened or modified.

Clean up recently modified files

  1. Expand the submenu at ReSharper | Edit | Cleanup Recent Files.

  2. Choose whether to run cleanup for all opened files or for all recently modified files.

    Cleanup... actions will prompt you to choose a cleanup profile, Silent Cleanup... actions will use the default cleanup profile selected on the Code Editing | Code Cleanup | Profiles page of ReSharper options ( Alt+R, O ).

  3. If you choose to clean up recently modified files, ReSharper will apply the selected cleanup profile to all files in the solution that were edited during the last 7 days.

    You can change the number of days during which changes should be considered recent on the Code Editing | Code Cleanup | General options page.

    You can also select Only changed parts of file to make sure that cleanup is applied to the code affected by your changes, and the rest of the code in the file is not modified.

Silent cleanup

You can also run code cleanup in the silent mode — that is, without displaying the Code Cleanup dialog. Since in this case you will not be able to choose a profile explicitly, you have to assign some cleanup profile to use for the silent code cleanup.

Assign a profile for silent code cleanup

  1. Select ReSharper | Options from the main menu or press Alt+R O.

  2. Go to the cleanup profiles settings page: Code Editing | Code Cleanup | Profiles.

  3. Select a cleanup profile on the left and click Set as default at the top of the options page.

  4. Click Save in the Options dialog to apply the modifications and let ReSharper choose where to save them, or save the modifications to a specific settings layer by choosing this layer from the Save To selector. For more information, see manage and share resharper settings.

Run code cleanup in silent mode

  1. Do one of the following:

    • To run silent code cleanup in a specific code file, open it in the text editor or select it in the Solution Explorer.

    • To apply silent code cleanup to a set of files (directory, project, or solution), select the corresponding item in the Solution Explorer.

  2. Press Control+Shift+Alt+F or choose ReSharper | Edit | Silent Cleanup Code from the main menu . Alternatively, you can press Control+Shift+A, start typing the command name in the popup, and then choose it there.

Available code cleanup tasks

The tables below list available cleanup tasks for different languages. If you need the cleanup to perform only a part of these tasks, you can create a custom cleanup profile for that.

Remove redundancies & apply optimizations

C#

Remove code redundancies

On the Code Inspection | Inspection Severity page of ReSharper options ( Alt+R, O ), in the Redundancies in Code categories of most languages, ReSharper 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, refer to 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, refer to 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, ReSharper automatically detects C# version based on the associated compiler. However, you can specify the target C# version explicitly for a project — right-click the project in the Solution Explorer, choose Edit project item properties from the context menu and use the C# Language Level selector .

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 unreachable code

Removes unnecessary code that will never be executed.

Remove unused #include directives

Removes never used #include directives.

Remove unused lambda captures

Removes unused capture if a local variable is captured by a lambda but not used inside the lambda body.

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

Replaces zero constants with nullptr in pointer contexts.

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

Replaces std::tie() or boost::tie() for unpacking a tuple or a pair with structured binding declarations.

Use 'contains' for associative containers wherer possible

Replaces find or count with the C++20 contains function.

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

Replaces the old erase-remove idiom with C++20 std::erase or std::erase_if library functions for erasing elements from any STL container.

Visual Basic

Remove code redundancies

On the Code Inspection | Inspection Severity page of ReSharper options ( Alt+R, O ), in the Redundancies in Code categories of most languages, ReSharper 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.

JavaScript/TypeScript

Correct 'var' to 'let'/'const' where possible

let and const are supported in the following cases:

  • In JavaScript code, if the target JavaScript language level is ECMAScript 6 (you can choose it on the Code Editing | JavaScript | Inspections page of ReSharper options ( Alt+R, O ))

  • In TypeScript 1.4, if the target ECMAScript 6 is selected in the project properties.

  • In TypeScript 1.5 or later.

Move let/const to most possible inner scopes

Moves variables defined outside of a function/compound statement, and so on closer to their usages if there are no other usages in outer scopes.

Convert string concatenations to template strings

In JavaScript code, if the target JavaScript language level is ECMAScript 6 (you can choose it on the Code Editing | JavaScript | Inspections page of ReSharper options ( Alt+R, O )) , as well as in TypeScript 1.4 or later, this option will convert string concatenations to template strings. For example:

var str1 = "Hello,"; var str2 = "Test: " + str1 + " World1";

will be converted to

const str1 = "Hello, "; const str2 = `Test: ${str1} World1`;

TypeScript specific

Remove redundant qualifiers

Use this option to remove redundant type name qualifiers.

C#

Update file header

Inserts or updates the file header comment that you can configure on the Code Editing | File Header Text page of ReSharper options ( Alt+R, O ) or using the file_header_template EditorConfig property. For more information, refer to File header style.

C/C++

Update file header

Inserts or updates the file header comment that you can configure on the Code Editing | File Header Text page of ReSharper options ( Alt+R, O ) or using the file_header_template EditorConfig property. For more information, refer to File header style.

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 Code Inspection | Inspection Severity page of ReSharper options ( Alt+R, O ). 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.
