formatting using table print gem using Ruby

Question

The output of my Json file is hash. I'm iterating over each line and using the tp gem to format it. My question is how do I format the width so that all my data is displayed neatly in the terminal.

I assume that it isn't formatting neatly because of the array within the hash.

 File.open("output.json", 'a+') do |file|
      1       data = { time_format: time_format, purchase: @purchase, quantity: @quantity, retail_price: @retail_price, purchasing_price: @purchasing_price }
      0       file.puts data.to_json                                                                                                                                         
      1     end  
transaction = File.open('output.json', 'a+').each do |line| 
           @transaction = JSON.parse(line)  
           if @transaction["time_format"].include?(review_date) 

           end     
         end       
         tp report



TIME_FORMAT      | PURCHASE | QUANTITY | RETAIL_PRICE | PURCHASING_PRICE
-----------------|----------|----------|--------------|-----------------

11/23/2013 08:08 | ["lig... | [1]      | [5.0]        | [3.0]           
11/23/2013 08:08 | ["lig... | [1, 1... | [5.0, 7.5... | [3.0, 4.0, 5....
11/23/2013 08:12 | ["lig... | [1]      | [5.0]        | [3.0]           
11/23/2013 08:13 | ["lig... | [1]      | [5.0]        | [3.0]           
11/23/2013 08:18 | ["lig... | [1]      | [5.0]        | [3.0]           

Edit: The gem is called Table Print

Answer 1

There are a couple ways you can change the column widths.

To change all columns at once:

tp.set :max_width, 60

To change an individual column, print as usual but give some column options:

tp report, :include => [:purchase => {:width => 60}]
