Use this page to enable or disable specific smart keys and to define which actions you want to be invoked automatically.

ItemDescription
Home When this checkbox is selected, on pressing Home, the caret is positioned at the first non-space character of the current line. Pressing Home subsequently moves the caret from the Smart Home position to the first column and back.
End (on blank line) When this checkbox is selected, on pressing End in an empty line, the caret is positioned with the indent, which RubyMine assumes to be reasonable in the current code point (indentation is based on the current Code Style Settings).
Insert pair bracketSelect this checkbox to have RubyMine automatically add a closing round or square bracket for each typed opening round or square bracket, respectively.
Insert pair quoteSelect this checkbox to have RubyMine automatically add a closing single or double quote for each typed opening single or double quote, respectively.
Reformat block on typing "}"If this checkbox is selected, then, on typing the closing curly brace, the enclosed code block is reformatted automatically, if the formatting of this code block does not match the selected code style.
Use 'CamelHumps' wordsSelect this checkbox to have RubyMine discern separate words within CamelHump names. Words within a name should start with a capital letter or an underscore. This option impacts some editor actions, for example:
  • Caret Move (Ctrl+Right/Ctrl+Left)
  • Caret Move with Selection (Ctrl+Shift+Right/Ctrl+Shift+Left)
  • Select Word at Caret (Ctrl+W)
  • Delete to Word Start/End (Ctrl+Backspace and Ctrl+Delete respectively)
  • Double-clicking (if Honor "CamelHumps" word settings when selecting using double click is enabled on the Editor | General settings page).
Surround selection on typing quote or brace If this checkbox is selected, the selected text on typing a quote, double-quote or brace, will be surrounded with these characters. If this checkbox is not selected, then the typed quotes, double-quotes or braces will replace the selection.
Add multiple carets on double Ctrl/ with arrow keys If this checkbox is selected, then:
  • pressing Ctrl (for Windows or *NIX) or (for Mac OS) twice plus up/down arrow keys leads to creating multiple carets.
  • pressing Ctrl (for Windows or *NIX) or (for Mac OS) twice plus left/right arrow keys or Home/End leads to creating a selection.

EnterUse this area to define the actions to be invoked by pressing Enter.
  • Smart Indent - select this checkbox to have RubyMine add a new line and position the caret in it, with the indent that RubyMine assumes to be reasonable in the current point of code (indentation is based on the current Code Style settings).

    If the checkbox is cleared, upon pressing Enter in a blank line, RubyMine adds a new line and positions the caret at the current non-space character column.

  • Insert pair '}' - select this checkbox to have RubyMine automatically position a closing brace } at the proper column when Enter is pressed in an empty line. In this case RubyMine seeks backward for the nearest unclosed opening brace { and places the closing one at the corresponding indentation level.
  • Insert documentation comment stub - this check box defines the behavior on pressing Enter after an opening documentation tag.
    • If this checkbox is selected, RubyMine generates a documentation comment stub.

      For the function comments, this stub contains the required tags (@param tags for each parameter declared in the signature, and @return). Refer to Creating Documentation Comments , Creating JSDoc Comments for details.

    • If this checkbox is not selected, only the closing tag is generated.
BackspaceUse this drop-down list to define the actions to be invoked by pressing Backspace key. The available options are:
  • Disabled - pressing Backspace returns the caret by one position at a time.
  • To nearest indent position
  • To proper indentation
Reformat on pasteUse this drop-down list to specify how to place pasted code blocks. The available options are:
  • None - The pasted code is inserted at the caret location as plain text without any reformatting or indenting.
  • Indent Block - The pasted code block is positioned at the proper indentation level, according to the current Code Style Settings, but its inner structure is not changed.
  • Indent Each Line- Each line of the pasted code block is positioned at the proper indentation level, according to the current Code Style Settings.
  • Reformat Block- The pasted code block is reformatted according to the currentCode Style Settings.
XML/HTMLIn this area, define the actions to be invoked automatically when editing XML or HTML code.
  • Insert closing tag on tag completion: select this checkbox to have RubyMine automatically insert a closing XML or HTML tag upon entering the corresponding opening one.
  • Insert required attributes on tag completion: select this checkbox to have RubyMine display a template with all mandatory attributes of the typed tag.
  • Insert required subtags on tag completion: select this checkbox to have RubyMine display a template with all mandatory subtags.
  • Start attribute on tag completion: select this checkbox to have RubyMine display a template with the first mandatory attribute of the typed tag.
  • Add quotes for attribute value on typing '=': select this checkbox to have RubyMine automatically add quotes for the value of the attribute that you are currently typing.
  • Auto-close tag on typing '</': select this check box to automatically add a closing tag after entering </. Clear this checkbox to turn off such auto-completion.
  • Simultaneous <tag></tag> editing:
    • When this checkbox is selected and you edit an opening tag the corresponding closing tag is automatically changed accordingly.
    • If this checkbox is cleared, editing the opening tag does not affect the closing tag which remains unchanged. As a result, the opening and closing tags do not match and the entire construct is underlined as erroneous.

    This checkbox controls the behaviour of RubyMine in the following contexts:

    • HTML files
    • HTML injections within JavaScript code
    • HTML with templates Handlebars/Mustache templates
    • Handlebars/Mustache template files with the extension .hbs
    • XML, XHTML files
    • DTD files
    • JSX files

CSSIn this area, define the selection of CSS identifiers/classes:
  • Select whole CSS identifier on double-click: If this checkbox is selected, double-click on a CSS identifier or class name selects the entire name up to the prefix:
    /help/img/idea/2017.3/select_css_identifier.png

    If this checkbox is not selected, double-click on a CSS identifier or class name selects a portion of a name up to the nearest hyphens:

    /help/img/idea/2017.3/select_css_identifier1.png
Start ruby interpolation in strings on #If this checkbox is selected, after pressing #, RubyMine will automatically insert opening and closing curly braces, with the cursor resting inside.

If this checkbox is cleared, then after typing #, you have to type the opening curly brace, to initiate Ruby interpolation. This is the default behavior.

/help/img/idea/2017.3/ruby_startInterpolation.png

Note that all sorts of Ruby coding assistance (code completion, syntax and error highlighting, intention actions and quick fixes) are available in the code interpolation.

AngularJSUse this area to define the behavior of AngularJS:
  • Auto-insert white space in the interpolation: If this checkbox is selected, a white space is automatically inserted between the braces: {{ }}.
    If this checkbox is not selected, the white space is not inserted: {{}}.
SQL Insert string concatenation on Enter. You may want to turn this option off, if the DBMS you are working with supports multiline string literals:

Say, there is the following fragment for PostgreSQL text value notes:

SET notes = 'Lightest element'

and the cursor is in front of the word element.

If the option is on, and you press Enter, the fragment will change to:

SET notes = 'Lightest ' || 'element'

Otherwise, the fragment will change to:

SET notes = 'Lightest element'
Qualify object on code completion. The selected option defines how the name of an object is inserted in the editor when using the code completion suggestion box.

  • Always. The qualified object names are always used, i.e. <schema_name>.<object_name>.
  • On collisions. The qualified object name is used only if the short name is ambiguous, e.g. when there is the object with the same name in more than one schema.
  • Never. The unqualified object names are always used.
