class DebuggerCode::LOC
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"

Prepends a marker “=>” or an empty marker to the line
.
@param [Integer] marker_lineno If it is equal to the `lineno`, then
prepend a hashrocket. Otherwise, an empty marker.
