CLion 2022.1 Help

Advanced Settings

Besides standard settings that you frequently use, CLion offers various advanced options that you can use to fine-tune the behavior of the specific product functionality.

Since the advanced settings consist of different sections, you can use the search field to quickly navigate to the section of interest or the needed option. You can also search for registry keys since some of advanced options have associated registry keys.

CMake

Use this section to configure additional options for CMake projects.

Use legacy generator for CMake 3.20 and higher

For CMake version 3.20 and higher, CLion uses CMake file API with Ninja generator by default. If you set this checkbox, the default generator will be Makefiles, and CLion will switch to CMake File API only if you specify a custom generator.

For older versions, CMake File API is used for the case of custom generator only regardless of this option's state. The default generator is Makefiles.

Do not trigger CMake reload on external changes if auto-reload is disabled

Select this option to completely disable automatic reload of CMake projects including external changes. See Load/reload CMake.

Perform initial profile configuration when a project is opened for the first time

Clear this checkbox if you prefer CLion not to automatically configure and show a default CMake profile when you open a project for the first time.

Reload CMake profiles sequentially

Select this option if you want CLion to reload CMake profiles one after another. By default, CMake profiles are reloaded in parallel, but sometimes it may cause issues when reloading CMake. Use this option to resolve such issues.

Clangd

Use this section to configure additional options for the Clangd engine.

Use global Clangd completion cache

Clean this checkbox if you prefer CLion not to use Clangd's global cache when performing code completion with Clangd. Disabling the completion cache can help reduce memory consumption and avoid unexpected crashes.

Bookmarks

Show only line bookmarks in popup

By default, CLion shows only line bookmarks in the bookmarks popup (Shift+F11 or Edit | Bookmarks | Show Line Bookmarks). Disable this option if you want to see other bookmarked items in the popup, for example, files or folders. For more information, see Bookmarks.

Debugger

Maximum number of recent expressions

Specify the number of expressions to be saved in history. This includes various fields like Evaluate expression and Goto address in disassembly/memory view.

Editor

Use this section to configure additional options for working in the editor.

Don't copy/cut the current line when invoking the Copy or Cut action with no selection

This option lets you override the default behavior of copying Ctrl+C or cutting Ctrl+X the whole current line when nothing is selected in the editor.

Render special characters, such as control codes, using their Unicode name abbreviations

When this option is selected, you can use the Unicode name abbreviations for special characters, such as control codes.

Tab character rendering

You can select one of the following options:

  • Horizontal line

  • > symbol

  • Long arrow

Left margin in distraction free mode

This option lets you adjust the left editor margin in the distraction-free and zen viewing modes.

By default, the editor text in these viewing modes is centered vertically and the text column width corresponds to the Hard wrap at option on the Editor | Code Style page of the IDE settings Ctrl+Alt+S. This means that if your code will be centered when formatted properly, but if there are long unwrapped lines, the text might go beyond the viewport while there is a large margin on the left. In such cases, you may want to decrease the left margin using this option.

Force soft wrap in documents with lines longer than n characters

The default number is 100000. Increasing this number might negatively affect the editor performance.

Move caret down after Comment with Line Comment action

This option lets you configure whether to move the caret to the next line if you comment a line with a line comment Ctrl+/. Note that if there is a selection in the editor, the caret will not move regardless of this option.

Editor Tabs

Besides the standard editor tabs options that CLion offers when you work with tabs in the editor, this section contains extra options that are also available as internal registry actions.

When navigating to a file, prefer selecting existing tab in inactive split pane

When you navigate to a file that is already opened in the inactive split, use this option to activate the existing file in that split pane instead of opening a new copy of the file in the active split.

Open declaration source in the same tab

When you navigate to a method, class or variable, the source file that contains their declaration will replace the current tab if there are no changes.

Open declaration source called from a detached window in the main IDE window

When you navigate to a method, class, or variable from a detached window, CLion will open the source file containing the declaration in the main editor.

Perform 'Hide All Tool Windows' / 'Restore Windows' with double-click on editor tab

When this option is enabled, you can double-click editor tabs to hide and restore all tool windows. Alternatively, you can do that by pressing Ctrl+Shift+F12 or by choosing Window | Active Tool Window | Hide All Windows/Restore Windows from the main menu.

Perform 'Maximize Editor' / 'Normalize Splits' with double-click on editor tab

When this option is enabled, you can double-click tabs in split editor tab groups to change relative size of the tab group: the first double-click will extend the tab and its group to the maximum and shrink all other groups to the minimum width/height; the second double-click will allocate the same width and height for each tab group.

Alternatively, you can choose Window | Editor Tabs | Maximize Editor/Normalize Splits from the main menu or pick these actions from the Find Action popup Ctrl+Shift+A.

This option can work together with Perform 'Hide All Tool Windows' / 'Restore Windows' with double-click on editor tab, but be prepared to have multiple changes in the IDE layout every time you double-click a fie tab.

Equalize proportions in nested splits

Use this option to even the size of multiple horizontal or vertical splits in the editor.

Find / Replace

Use this section to configure extra options when working with Find and replace in project.

Maximum number of results to show in Find in Files/Show Usages preview

The default maximum number of results is 100. Increasing this limit might significantly increase memory usage.

IDE

Use this section to configure extra options on storing different entities of your project.

Maximum number of recent projects

Use this option to change the default number of stored recent projects, which is 50.

Maximum number of recent files

Use this option to change the default number of stored recent files, which is 50.

Maximum number of recent locations

Use this option to change the default number of stored recent locations, which is 25.

Duration of storing changes in Local History

Use this option to specify the number of days for which you want to keep changes in the local history.

Markdown

Hide floating toolbar

When you select some text in a Markdown file, CLion shows a floating toolbar with various formatting options. Select this checkbox if you don't want to see the floating toolbar, then reopen the tab to apply the changes.

Makefile

Use this section to configure additional options for Makefile projects.

Implicit Make output analyzer options

In this field, you can edit the Make output analyzer flags.

For example, if you remove the --just-print option, your project will be analyzed and built in a single pass. However, this can cause performance issues. Also, in this case the command output and Make output will be mixed, which can affect the analyzer accuracy.

Save Make output to log files...

Set this checkbox to collect the Make output logs.

Use POSIX shell parser on MinGW toolchain (Windows)

If you are working on Windows with MinGW, you can set this checkbox to switch from Windows batch to the POSIX shell parser.

Project View

Use this section to configure additional options for working in Project tool window.

Move focus to editor when Enter is pressed

When this option is selected, you can press Enter while in the Project view to switch focus to the editor.

When collapsing a node, also collapse all expanded nodes under it

When this option is selected, CLion collapses subnodes as well as the parent node.

Increase font size in Project view

Select this option if you want to change the size of font in the Project view. You need to restart CLion.

Python

Swap the order of actual and expected assertions in Pytest

By default, CLion provides the expected == actual pytest assertion. Select this checkbox to change the order of the assertion parameters to actual == expected.

Pytest: do not add "--no-header --no-summary -q"

Use this checkbox to manage the test output generated by pytest. Select it to keep rendering the header and summary.

Run/debug

Temporary configurations limit

Use this option to change the default number of stored temporary run/debug configurations, which is 5.

Confirm rerun with process termination

When you call rerun for a running process, CLion prompts you to confirm the action of terminating the existing process and launching a new one. You can change the default behaviour by clearing this checkbox.

Make configurations pinned by default

Select this option to automatically pin tabs that open in the Run tool window after you run configurations.

Generate configurations for new CMake/Makefile targets automatically

When you add new targets and reload your CMake or Makefile project, CLion automatically creates the corresponding CMake Application or Makefile Application configurations.

Delete configurations for missing CMake/Makefile targets automatically

When you delete targets and reload your CMake or Makefile project, CLion automatically deletes the corresponding CMake Application or Makefile Application configurations.

SSH

Configuration files parser

Select a parser:

  • Legacy: use the legacy parser for ~/.ssh/config.

  • OpenSSH: use the parser based on ssh -G. OpenSSH must be installed on your computer.

Custom path to an OpenSSH tool

On macOS, the icon can be used to drag a file to a different application.

Use words instead of symbols for macOS keyboard shortcuts

Select this option if you want to see shortcuts with words instead of symbols.

Cyclic scrolling in lists and trees

Select the last element when pressing Up on the first element, and vice versa.

Position mouse cursor on default button in dialogs

When this option is selected, the mouse cursor is placed on the default button (usually it is OK) in a dialog.

Disable double modifier key shortcuts

You can disable shortcuts where a double key is used. For example, Shift or Ctrl.

Version Control
