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 2>&1` 

and File IO

 my_file = File.new(@dir_+"/myfile.out",'w+')            my_file.puts `#{pp get_submap_from_final(all_mapping_file,final_map)}` 

It always prints to console and doesnt write to a file.

Also there has to be an easier way to write to file in one line in ruby ? instead of doing File.new and then writing to a file ?

Answer 1

require 'pp'  File.open("test.txt","w") do |f|   PP.pp(self,f) end
