Code Style. Ruby

Use this page to configure code style options for Ruby files. When you change these settings, the Preview pane shows how this will affect your code.

Tabs and Indents

Item	Description
Use tab character	Use the `Tab` key for indentation. When the checkbox is cleared, RubyMine uses spaces instead of tabs.
Smart tabs	If this checkbox is selected, the indentation for nested code blocks will use tabs and spaces as needed, while alignment indentation will use only spaces. If this checkbox is cleared, only tabs are used. This means that a group of spaces that fits the specified tab size is automatically replaced with a tab, which may result in breaking fine alignment. The Smart tabs checkbox is available if the Use tab character option is enabled.
Tab size	In this field, specify the number of spaces included in a tab.
Indent	In this field, specify the number of spaces to be inserted for each indent level.
Continuation indent	Specify the indentation for lines that continue from the previous line, making it clear that they are part of the same statement or block of code. Continuation indents are used when a single statement is too long to fit on one line.
Keep indents on empty lines	If this checkbox is selected, RubyMine will keep indents on the empty lines as if they contained some code. If this checkbox is cleared, RubyMine will delete the tab characters and spaces.
Use indents relative to expression start	Use this checkbox to switch between the two possible indentation behaviors: If this option is disabled, code blocks will be aligned with the nearest ancestor block that begins on a new line. If the option is enabled, the blocks of code will be formatted in columns.
Indent visibility modifiers	Use the checkbox to configure indentation for visibility modifiers. By default, the checkbox is selected, and visibility modifiers are indented. When the checkbox is not selected and visibility modifiers aren't indented, all inner methods will be indented automatically.
Indent methods after visibility modifiers	Select the `public`, `protected` or `private` checkboxes to create an extra indentation after the corresponding access modifier.

Spaces

Use this tab to specify where you want RubyMine to insert spaces automatically. Select the checkboxes next to the description of relevant locations and check the results in the Preview pane.

Wrapping and Braces

Visual guides	Allows you to specify the position of visual guides that help you control the width of the code. If you want to specify several visual guides, enter numbers separated by a comma, for example, `45, 60`.
Keep when reformatting	Use the options to configure exceptions that RubyMine will make when reformatting the source code. By default, the Line breaks checkbox is selected. RubyMine in this case will ignore line breaks when reformatting the source code. If your code contains lines that are shorter than a standard convention, you can convert them by disabling the Line breaks checkbox before reformatting.
List items	Use these options to format multiline code constructs. For example, if Align when multiple is enabled, RubyMine aligns hash items. options = {:font_size => 10, :font_family => "Arial"}
Assignments and hashes	Use these options to format variable assignments and hash values. For example, if Align right parts is enabled, RubyMine aligns hash values. options = {:font_size => 10, :font_family => "Arial"}
Chained method calls	Use the options to format multiline chained method calls. For example, the Alignment option allows you to align chained method calls by the initial receiver or leading dots. Leading dots @posts = Post.where(author_id: @user.person_id, public: true) .order("created_at DESC") .limit(25) Initial receiver @posts = Post.where(author_id: @user.person_id, public: true) .order("created_at DESC") .limit(25)
Empty declarations	Specify how to format declarations of empty classes, methods, and modules. As is Single-line def foo; end Multi-line def foo; end

Blank Lines

Use this tab to define where and how many blank lines you want RubyMine to retain and insert in your code after reformatting. The results are displayed in the Preview pane.

Keep Maximum Blank Lines

In this area, specify the number of extra blank lines to be kept after reformatting.

Minimum Blank Lines

In this area, configure whether to have or not to have extra empty lines after the blocks of import statements and around classes, fields, methods, or functions. In the field next to each option, specify the minimum number of extra blank lines to be left.

In this area, configure whether to have or not to have extra empty lines around top-level blocks and nested selectors. In the field next to each option, specify the minimum number of extra blank lines to be left.

Code Generation

Add parentheses around method arguments	Specify whether to add parentheses around arguments of a generated method. For example, this option is in effect for methods generated from usage or overridden method stubs.
Convert {} blocks to do..end by Enter	Enable this option to convert `{}` blocks to `do..end` automatically by pressing `Enter`.
