IO streams inconsistencies in different versions of ruby - ruby

Question

I am trying to create a way to mirror all three standard (input,out and error) streams of a ruby program to different files.
I was able to do that for output stdout and error stderr streams.
However there is inconsistencies between different ruby version on how they handle IO streams.
Bottom line is
How do I handle stream duplication in older versions of ruby (point 2) ?
Issue Summary
Older ruby versions don't support variadic arguments while new version does, that can be handled.
On same older versions, even if I try to work around it by join ing arguments, stream contents are duplicated.
Variadic arguments issue
In ruby 2.1.x and ruby 2.2.x, $stdout accepts only single arguments.
So for those version of ruby
$stdout.write("Test") # works
while this doesn't work
$stdout.write("Hello","Test")
ArgumentError: wrong number of arguments (2 for 1)
from (pry):6:in `write'
However for ruby version 2.5.x and 2.6.x variable parameters works
$stdout.write("Hello")
$stdout.write("This","works", "as", "well")
Duplication of stream content, if I add version specific code to handle stream parameters, older ruby version end up duplicating the stream content.
Older ruby version
driver.rb:4 in `puts` --> This is it driver.rb:4 in `puts` -->
while on
New ruby versions
driver.rb:4 in `puts` --> This is it
Here is the code

DEFAULT_RECORDING_PATH = "recordings"
def initialize(recording_path)
#recording_paths = recording_path || DEFAULT_RECORDING_PATH
end
def self.record
input_log,output_log,error_log = setup_files
$stdout = ReoxIO.new(STDOUT,output_log)
$stderr = ReoxIO.new(STDERR,error_log)
yield
end

def self.setup_files
["input.log","output.log","error.log"].map do |file_name|
self.setup_file(file_name)
end
end
def self.setup_file(file_name)
file = ReoxFile.open(File.join(__dir__,file_name),"a")
file.sync = true
