Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

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.

Examples:

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"

#add_line_number(max_width = 0) ⇒ void

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

  padded = lineno.to_s.rjust(max_width)
  tuple[0] = "#{ padded }: #{ line }"
end

#add_marker(marker_lineno) ⇒ void

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

This method returns an undefined value.

Prepends a marker “=>” or an empty marker to the line.

Parameters:
