pretty print json in ruby

gistfile1.rb

require 'json'
my_json = { :array => [1, 2, 3, { :sample => "hash"} ], :foo => "bar" }
puts JSON.pretty_generate(my_json)
Which gets you...

{
  "array": [
    1,
    2,
    3,
    {
      "sample": "hash"
    }
  ],
  "foo": "bar"
}

Yeah, but what if I want to put it into an HTML code block?

Yes, I think this one is good.
Suppose I have an original json-format string: json_string.

require 'json'
json_string = '{"a": 1, "b":2}'
JSON.generate(JSON.parse(json_string)) # This will generate a pretty formatted one.

@kevinnio If you want to put it into a <code></code> block in Rails, then just do it, that't the Rails stuff.
If you also want some highlight, then you can try highlight.js.
