This is Perl module App::jl.

SYNOPSIS

The jl command allows you to show the "JSON in JSON" log nicely. Recursively decode JSON in JSON string like below

$ echo '{"foo":"{\"bar\":\"{\\\"baz\\\":123}\"}"}' | jl
{
   "foo" : {
      "bar" : {
         "baz" : 123
      }
   }
}

A complecated log can be converted to nice JSON structure to treat a tool like jq .

echo '{"service":"Foo-Service","pod":"bar-baz-12345","message":"{\"log\":\"[PID:12345]<info>\\nThis is log message. foo, bar, baz, qux, long message is going to be splitted nicely to treat JSON by jq without any special function\",\"timestamp\":1560526739}"}' | jl -xxxx
{
   "message" : {
      "log" : [
         [
            "[PID:12345]",
            "<info>"
         ],
         [
            "This is log message. foo",
            "bar",
            "baz",
            "qux",
            "long message is going to be splitted nicely to treat JSON by jq without any special function"
         ]
      ],
      "timestamp" : "2019-06-15 00:38:59"
   },
   "pod" : "bar-baz-12345",
   "service" : "Foo-Service"
}
