Make JSON readable

gistfile1.txt

# This is just a quick little script to use Ruby's JSON.pretty_generate() method without having to start an irb session.
# To call this JSON prettier just pass the flattened JSON in as an argument. 

# To run it:
#  1) copy the code below into a file called json_viewer.rb
#  2) > ruby json_viewer.rb '{"foo":"bar","yadda":"yadda","blah":["blah1","blah2"]}'

require 'json'

unless ARGV[0].nil?
  
  begin
    json = JSON.parse(ARGV[0])

    puts JSON.pretty_generate(json)
    
  rescue Exception => e
    puts "You must supply a valid json string! (e.g. > ruby json_viewer '{\"foo\":\"bar\",\"yadda\":\"yadda\"}')"
  end

else
  puts "You must supply a json string! (e.g. > ruby json_viewer '{\"foo\":\"bar\",\"yadda\":\"yadda\"}')"
end
