    The Inline refactoring lets you reverse the extract refactoring for variables and methods.

    The animation below demonstrates how to inline a variable to a string:

    To inline a variable/method:

    Inline Variable

    The Inline Variable refactoring replaces redundant variable usage with its initializer. This refactoring is opposite to Extract Variable.

    Before

    After

    name = "JetBrains"
puts "Hello from #{name}"
    puts "Hello from JetBrains"

    Inline Method

    Inline Method results in placing method's body into the body of its caller(s).

    Before

    After

    def test
  c=add(a,b)
  d=add(a,c)
end

def add(a, b)
  a+b
end
    def test
  c = a + b
  d = a + c
end
