In this area, choose the code style scheme and change it as required. Code style scheme settings are automatically applied every time RubyMine generates, refactors, or reformats your code.

Code styles are defined at the project level and at the IDE level (global).

  • At the Project level, settings are grouped under the Project scheme, which is predefined and is marked in bold. The Project style scheme is applied to the current project only.

    You can copy the Project scheme to the IDE level, using the Copy to IDE... command.

  • At the IDE level, settings are grouped under the predefined Default scheme (marked in bold), and any other scheme created by the user by the Duplicate command (marked as plain text). Global settings are used when the user doesn't want to keep code style settings with the project and share them.

    You can copy the IDE scheme to the current project, using the Copy to Project... command.

SchemeFrom this drop-down list, select the scheme to be used. The predefined schemes are shown bold. The custom schemes, ones created as copies of the predefined schemes, are in plain text. The location where the scheme is stored is written next to each scheme, for example, the Default scheme is stored in the IDE, the Project scheme is stored in the project.

Tabs and Indents

Use tab character
  • If this checkbox is selected, tab characters are used for indentation and for code reformatting.
  • When the checkbox is cleared, RubyMine uses spaces instead of tabs.
Smart tabs An indentation consists of two parts. One part results from nesting code blocks and the other part is determined by alignment.
  • If this checkbox is selected, the part that results from nesting contains both tabs and spaces (if necessary), while the part defined by alignment consists only of spaces.
  • If this checkbox is cleared, only tabs are used. This means that after reformatting a group of spaces that fits the specified tab size is automatically replaced with a tab, which may result in breaking fine alignment.
Tab sizeIn this text box, specify the number of spaces that fits in a tab.
IndentIn this text box, specify the number of spaces (or tabs if the Use Tab Character checkbox is selected) to be inserted for each indent level.
