RubyMine 2021.3 Help

Smart Keys

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

Item

Description

Home moves caret to first non-whitespace character

When this checkbox is selected, on pressing Home, the caret is positioned at the first non-whitespace 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 moves caret to indent position

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 brackets (), [], {}, <>

Select this checkbox to have RubyMine automatically add a closing bracket for each typed opening bracket, respectively.

Insert pair quote

Select 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" words

Select 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 MoveCtrl+Right/Ctrl+Left

  • Caret Move with Selection (Ctrl+Shift+Right/Ctrl+Shift+Left)

  • Select Word at CaretCtrl+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).

Honor "CamelHumps" words settings when selecting on double click

Select this checkbox to have RubyMine invoke the CamelHumps selection when words are selected by double-clicking.

This feature works only if the Use 'CamelHumps' words option is enabled.

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 plus up/down arrow keys leads to creating multiple carets.

  • pressing Ctrl plus left/right arrow keys or Home/End leads to creating a selection.

For more information, see the Multicursor section.

Jump outside closing bracket/quote with Tab when typing

If this checkbox is selected, pressing Tab when typing inside brackets/quotes will move the caret outside the closing bracket/quote. If this checkbox is not selected, pressing Tab will insert the Tab character.

Note that this only works on initial typing: during subsequent editing, pressing Tab inside brackets/quotes will insert the Tab character.

Enter

Use 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 at 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 checkbox defines the behavior on pressing Enter after the opening documentation comment. This functionality works only for JavaScript , Java, Groovy, and Swift.

    • 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 , JSDoc comments for details.

    • If this checkbox is not selected, only the closing part of the comment is generated.

Unindent on Backspace

Use this 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 indent position

Reformat on paste

Use this 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 current Code Style Settings.

Kotlin

Use this area to configure the smart keys options for Kotlin.

  • Convert pasted Java code to Kotlin: select this option to convert any Java code to Kotlin on paste. RubyMine displays the Convert Code from Java dialog. If you don't want RubyMine to show the dialog, select the Don't show Java to Kotlin conversion dialog on paste option.

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.

Ruby start interpolation

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.

Continue comments on Enter

If you are editing a comment in the Ruby file, pressing Enter moves the caret at the beginning of the next line and adds the # character automatically. You can use this option to disable this capability.

AngularJS

Use 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: {{}}.

HTML/CSS

Use this page to configure the editor behavior for HTML, XML, and CSS.

Item

Description

XML/HTML

In 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 '=' and attribute completion: 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 checkbox 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.

    The Simultaneous <tag></tag> editing checkbox controls the behaviour of RubyMine in the following contexts:

    • HTML files

    • HTML injections within JavaScript code

    • HTML with Handlebars/Mustache templates

    • Handlebars/Mustache template files with the extension .hbs

    • XML, XHTML files

    • DTD files

    • JSX files

CSS

In this area, define the selection of CSS identifiers/classes:

  • Select whole CSS identifier on double-click: if this checkbox is selected, double-clicking a CSS identifier or class name selects the entire name up to the prefix. For example, double-clicking gray within <div class="text-gray-600"> select the whole class name text-gray -600:

    Select whole CSS identifier on double-click: ON

    If this checkbox is cleared, double-clicking a CSS identifier or class name selects a portion of the name up to of within the nearest hyphens:

    Select whole CSS identifier on double-click: OFF

JSON

Use this page to configure the editor behavior for JSON.

Item

Description

JSON

The settings in this area control automatic adding of commas, quotes, and whitespaces in JSON context in compliance with the JSON syntax.

JavaScript

Use this page to configure the editor behavior for JavaScript.

Item

Description

Start template string interpolation on typing '$'

Select this checkbox to insert expressions with normal strings after the $ sign. See Expression interpolation for details.

Escape text on paste in string literals

By default, RubyMine automatically inserts backslash escape symbols (\) when you paste text into a JavaScript string. Clear the checkbox to suppress automatic text escaping.

Convert attributes when pasting HTML into JSX files

By default, when you copy a piece of HTML code with class attributes or on-event handlers and paste it into JSX, RubyMine automatically replaces these attributes with React-specific ones (className, onClick, onChange, and so on.)

To copy HTML code to JSX "as is", clear the checkbox or use Paste SimpleCtrl+Alt+Shift+V.

Insert parentheses on completion

By default, this option is turned on and RubyMine automatically inserts a pair of opening and closing parentheses when you complete a function/method.

Insert parentheses on completion is enabled

Clear the checkbox to suppress inserting parentheses automatically.

If you use an opening parentheses ( instead of Enter) to apply the selected item from a completion list, parentheses will be inserted automatically no matter whether the option is turned on or off.

Insert parenthese on completion is disabled. Parentheses are still inserted on completion with an opening brace.

To use an opening parentheses ( instead of Enter) to apply the selected item from a completion list, open the Settings/Preferences dialog (Ctrl+Alt+S) , go to Editor | General | Code Completion, and select the Insert selected suggestion by pressing space, dot, or other context-dependent keys checkbox. See Use specific keys to insert suggestions for details.

SQL

Use this page to configure the eiditor behavior for SQL.

Item

Description

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'

Close code blocks on Enter

When you start a code block with an opening keyword (BEGIN, LOOP, BEGIN TRY, and others) and press Enter, the code block closes with the corresponding closing keywords (END, END LOOP, END TRY, and others).

Close code blocks on Enter

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, for example <schema_name>.<object_name>.

  • On collisions: the qualified object name is used only if the short name is ambiguous, for example when there is the object with the same name in more than one schema.

  • Never: the unqualified object names are always used.

Yaml

Use this page to configure the editor behavior for Yaml.

Item

Description

Auto expand key sequences upon paste

With this option selected, RubyMine properly formats key sequences when you paste them from the clipboard. For example, the key2.another_key sequence pasted from the clipboard will be displayed with the correct hierarchy.

Auto expand key sequences upon paste is on

Otherwise, if the option is cleared, key sequences are pasted from the clipboard "as is", hierarchy is not preserved, and consequently proper highlighting is not provided.

Auto expand key sequences upon paste is off
