Constructor Details

#initialize(apply_sed_operation_to_these_programs = ARGV, run_already = true) ⇒ ApplySedOperations

#

initialize

The first argument to this method will be the sed-operations that this class will perform. It should be an Array, but if a String is given then it will be converted into an Array anyway.
