Rename refactorings

The Rename refactoring lets you change the following names:

• Files and directories

• Classes

• Methods and its parameters

• Variables

• Components of Rails applications

• Rails named scopes

RubyMine automatically changes all the references to renamed items throughout code.

Renaming local variables or private methods can be done easily inline since only the limited scope is affected. Renaming classes or public methods could potentially impact a lot of files. In this case, we suggest that you preview potential changes before you refactor.

The procedure below demonstrates how to rename a class method.

class Song
  def initialize(name, artist)
    @name = name
    @artist = artist
  end
  def to_s
    "Song: #{@name}--#{@artist}"
  end
end

song = Song.new("My Way", "Sinatra")
puts song.to_s

class Song
  def initialize(name, artist)
    @name     = name
    @artist   = artist
  end
  def to_string
    "Song: #{@name}--#{@artist}"
  end
end

song = Song.new("My Way", "Sinatra")
puts song.to_string
