Detailed Description

Writes a Value in JSON format in a human friendly way.

The rules for line break and indent are as follow:

• Object value:
  • if empty then print {} without indent and line break
  • if not empty the print '{', line break & indent, print one value per line and then unindent and line break and print '}'.
• Array value:
  • if empty then print [] without indent and line break
  • if the array contains no object value, empty array or some other value types, and all the values fit on one lines, then print the array on a single line.
  • otherwise, it the values do not fit on one line, or the array contains object or non empty array, then print one value per line.
