neat formatting seems to ignore hash levels deeper than 2

[fawaf]

the command to generate the below output is JSON.neat_generate(env, after_colon: 1, padding: 1). env contains the ruby hash object used to generate the output.

the output somehow has the _template hash all in one line, which is not expected:

{
  "name": "foo",
  "description": "some environment",
  "cookbook_versions": {
...snip...
    "seven_zip": "= 2.0.2",
    "windows": "= 1.39.1",
    "zookeeper": "= 9.0.1"
  },
  "json_class": "Chef::Environment",
  "chef_type": "environment",
  "default_attributes": {
    "blah": {
      "_template": { "elb_logs_index_template": { "settings": { "number_of_shards": 6 } } }
    }
  },
  "override_attributes": {}
}

the expected output is:

{
  "name": "foo",
  "description": "some environment",
  "cookbook_versions": {
...snip...
    "seven_zip": "= 2.0.2",
    "windows": "= 1.39.1",
    "zookeeper": "= 9.0.1"
  },
  "json_class": "Chef::Environment",
  "chef_type": "environment",
  "default_attributes": {
    "blah": {
      "_template": {
        "elb_logs_index_template": {
          "settings": {
            "number_of_shards": 6
          }
        }
      }
    }
  },
  "override_attributes": {}
}

This is an expected feature, depending on your wrapping width. The default is 80, for which that last value fits on one line. If you want to force it to always wrap, use wrap:true, or a smaller width. For example:

require 'neatjson'
h = {a:{b:{c:{d:{e:{f:"deep"}}}}}}
JSON.neat_generate(h, after_colon:1, padding:1)

puts JSON.neat_generate(h, after_colon:1, padding:1)
#=> { "a": { "b": { "c": { "d": { "e": { "f": "deep" } } } } } }

puts JSON.neat_generate(h, after_colon:1, padding:1, wrap:40)
#=> {
#=>   "a": {
#=>     "b": {
#=>       "c": { "d": { "e": { "f": "deep" } } }
#=>     }
#=>   }
#=> }

puts JSON.neat_generate(h, after_colon:1, padding:1, wrap:30)
#=> {
#=>   "a": {
#=>     "b": {
#=>       "c": {
#=>         "d": {
#=>           "e": { "f": "deep" }
#=>         }
#=>       }
#=>     }
#=>   }
#=> }
puts JSON.neat_generate(h, after_colon:1, padding:1, wrap:true)
#=> {
#=>   "a": {
#=>     "b": {
#=>       "c": {
#=>         "d": {
#=>           "e": {
#=>             "f": "deep"
#=>           }
#=>         }
#=>       }
#=>     }
#=>   }
#=> }
