Creating Documentation Comments

Creating tags

To create tags in a documentation comment block

  1. In a comment block, select the desired empty line and type @ or: character.
  2. Press Ctrl+Space, or just wait for Code Completion to display the suggestion list:
    rm doc comment tags
  3. Select a tag from the suggestion list. For example, you can specify the parameters type, or return type.
  4. If a certain tag has several values, press Ctrl+Space after the tag, and select the desired value from the suggestion list. For example, RubyMine suggests to select the desired parameter name.
    rm param completion

Creating and fixing doc comments

Documentation comment can be created with the dedicated action Fix Doc Comment. It can be invoked by means of Find Action command.

Press Ctrl+Shift+A, with the caret somewhere within a class, method, function, or field, which should be documented, and enter the action name Fix Doc String. The missing documentation stub with the corresponding tags is added. For example:

function loadDocs(myParam1, myParam2){}

Type the opening documentation comment and press Enter to generate the documentation comment stub:

/** * @param myParam1 * @param myParam2 */

The next case lays with fixing problems in the existing documentation comments.

For example, if a method signature has been changed, RubyMine highlights a tag that doesn't match the method signature, and suggests a quick fix.

For JavaScript, RubyMine suggests an intention action UpdateJSDoc comment. You can also press Ctrl+Shift+A, and type the action name:

fix doc comment js
