Work with source code
If a file is read-only, it is marked with the closed lock icon 
in the status bar, in its editor tab, or in the Project tool window. If a file is writable, it is marked with the open lock icon 
in the Status bar.
Open file in the editor or select it in the Project tool window.
Do one of the following:
From the main menu, select or .
Click the lock icon in the status bar.
If a read-only status is set by a version control system, it's suggested that you use RubyMine version control integration features. For more information, see Version control.
In the editor, place the caret at the item you want to select and press Ctrl+W/Ctrl+Shift+W to extend or shrink your selection.
For example, in a plain text file, the selection starts within the whole word then extends to the sentence, paragraph, and so on.
The example below demonstrates selecting various code constructs in the editor.
GifIf you need just to highlight your braces, place the caret immediately after the block closing brace/bracket or before the block opening brace/bracket.
Lines of code
note
If you need to undo or redo your changes, press Ctrl+Z/Ctrl+Shift+Z respectively.
To add a line after the current one, press Shift+Enter. RubyMine moves the caret to the next line.
To add a line before the current one, press Ctrl+Alt+Enter. RubyMine moves the caret to the previous line.
To duplicate a line, press Ctrl+D.
To sort lines alphabetically in the whole file or in a code selection, from the main menu, select or . These actions might be helpful when you work with property files, data sets, text files, log files, and so on. If you need to assign shortcuts to those actions, refer to Configure keyboard shortcuts for more information.
To delete a line, place the caret at the line you need and press Ctrl+Y.
To join lines, place the caret at the line to which you want to join the other lines and press Ctrl+Shift+J. Keep pressing the keys until all the needed elements are joined.
You can also join string literals, a field or variable declaration, and a statement. Note that RubyMine checks the code style settings and eliminates unwanted spaces and redundant characters.
To split string literals into two parts, press Enter.
RubyMine splits the string and provides the correct syntax. You can also use the Break string on '\n' intention to split string literals. Press Alt+Enter or click
to select this intention.To comment a line of code, place the caret at the appropriate line and press Ctrl+/. Press Ctrl+/ again on the same line to uncomment it.
To move a line up or down, press Alt+Shift+Up or Alt+Shift+Down respectively.
To move (swap) an XML or HTML tag attribute to the left or to the right, place the caret at it, or select it and press Ctrl+Alt+Shift+Left for left or Ctrl+Alt+Shift+Right for right.
Code statements
Unwrap or remove statement
Place the caret at the expression you want to remove or unwrap.
Press Ctrl+Shift+Delete.
RubyMine shows a popup with all actions available in the current context. To make it easier to distinguish between statements to be extracted and statements to be removed, RubyMine uses different background colors.
Select an action and press Enter.
Code folding
Folded code fragments are shown as shaded ellipses (
). If a folded code fragment contains errors, RubyMine highlights the fragment in red.
note
If RubyMine changes code in the folded fragment during the code reformatting, the code fragment will be automatically expanded.
