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.

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.

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

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.

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

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

Open README.md file if there are no open files on project startup

If you select this option, RubyMine will open a README.md file if there aren't any opened files when you start your project.

Terminal scrollback buffer size

Use this option to increase the buffer size in the terminal.

Move focus to the editor with Escape

Enable Commit tool window

When you select this option, RubyMine displays the Local Changes and Shelf tabs in a separate tool window.
