Class Pry::Code::LOC
In: lib/pry/code/loc.rb
Parent: Object

Represents a line of code. A line of code is a tuple, which consists of a line and a line number. A `LOC` object‘s state (namely, the line parameter) can be changed via instance methods. `Pry::Code` heavily uses this class.

@api private @example 

  loc = LOC.new("def example\n  :example\nend", 1)
  puts loc.line
  def example
    :example
  end
  #=> nil

  loc.indent(3)
  loc.line #=> "   def example\n  :example\nend"
