pretty print to a file in ruby

Question

I am trying to pretty print a hash to a file.

I tried unix redirects [added different flags to it incrementally] :

`echo #{pp  mymap} | tee summary.out          


        

Answer 1

The use of backticks here is perplexing since those are used for executing shell commands.

What you probably mean is:

File.open(@dir_+"/myfile.out",'w+') do |f|
  f.write(pp(get_submap_from_final(all_mapping_file,final_map)))
end

The pp method always writes to the console so you might see it and still have it written.
