Advanced Settings

Maximum number of recent expressions

The number of expressions to be saved in the Evaluate expression history.

Connect to Docker automatically at restart

Select to connect to the configured Docker daemon after RubyMine starts.

Image registry entities loading limit

For performance reasons, by default, RubyMine shows only the first 100 images in a Docker registry. Increase this number if you need to list more. This will also increase the memory usage.

The log tab should be the first tab for the docker container

Show the Log tab as the first tab in the container overview pane.

Apply :z mount option to almost any bind volume for SELinux systems

Add :z configuration flags to Docker bind mounts in order to connect volumes to Docker containers on SELinux workstations.

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 Control+C or cutting Control+X the whole current line when nothing is selected in the editor.

Don't select the copied line after invoking the Copy action with no selection

By default, when you use Control+C without selecting anything, the whole line gets copied. With this action, you can avoid that selection.

When pasting a line copied with no selection

You can change the default Paste above the caret line behavior, and select either Paste at the caret line that restores the old Copy / Paste behavior or Trim if pasted middle line that will remove the unnesessary spaces before and after the copied line if it is pasted in the middle of the line.

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.

Show zoom indicator

Use this option to see an indicator that shows the current font size and the option to revert it back to default while zooming your code in or out in the editor.

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 Control+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 Control+/. Note that if there is a selection in the editor, the caret will not move regardless of this option.

RubyMine analyzes search results, detects the most common usage patterns, and categorizes all found usages into groups based on their structural similarity. These usage clusters appear in the Preview tab.

For more information, refer to Search for usages in a 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.

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

Delete empty line comment with Enter

Use custom file icons

Select if you want RubyMine to display file icons in the Project tool window based on the content of the files (for example, for classes, for modules, and so on).

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, RubyMine 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.

Maximum number of recent run configurations in the new UI

Disable the option to display tool window header icons all the time.

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.

Recursively clone submodules in the project

When this option is selected, during the checkout from Git, git clone --recurse-submodules is used that clones the main repository with all available submodules.
