module Kernel - JSON implementation for Ruby

JSON(object, opts = nil) click to toggle source

If object is string-like, parse the string and return the parsed result as a Ruby data structure. Otherwise, generate a JSON text from the Ruby data structure object and return it.

The opts argument is passed through to generate/parse respectively. See generate and parse for their documentation.

# File lib/json/common.rb, line 1127
def JSON(object, opts = nil)
  JSON[object, opts]
end

j(*objs) click to toggle source

Outputs objs to STDOUT as JSON strings in the shortest form, that is in one line.

# File lib/json/common.rb, line 1093
def j(*objs)
  if RUBY_VERSION >= "3.0"
    warn "Kernel#j is deprecated and will be removed in json 3.0.0", uplevel: 1, category: :deprecated
  else
    warn "Kernel#j is deprecated and will be removed in json 3.0.0", uplevel: 1
  end

  objs.each do |obj|
    puts JSON.generate(obj, :allow_nan => true, :max_nesting => false)
  end
  nil
end

jj(*objs) click to toggle source

Outputs objs to STDOUT as JSON strings in a pretty format, with indentation and over many lines.

# File lib/json/common.rb, line 1108
def jj(*objs)
  if RUBY_VERSION >= "3.0"
    warn "Kernel#jj is deprecated and will be removed in json 3.0.0", uplevel: 1, category: :deprecated
  else
    warn "Kernel#jj is deprecated and will be removed in json 3.0.0", uplevel: 1
  end

  objs.each do |obj|
    puts JSON.pretty_generate(obj, :allow_nan => true, :max_nesting => false)
  end
  nil
