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

Given the mymap from the question, you can use the "show_data" gem, which provides two methods: show_data and format_data. The latter produces a "pretty-printed" string of its argument which can then be fed to any output method.

require 'show_data'

$stderr.puts format_data(mymap)

For example:

myhash = { 'owners' => 21050, 'users' => 16877, 'portfolios' => 583, 
           'properylists' => 0, 'properties' => 29504, 'units' => 62688, 
           'tenants' => 85856 }
$stderr.puts format_data(myhash)

on STDERR:

 {      'owners' => 21050,
         'users' => 16877,
    'portfolios' => 583,
  'properylists' => 0,
    'properties' => 29504,
         'units' => 62688,
       'tenants' => 85856
}
