exqt / json.lua

A lightweight JSON library for Lua

a fork of rxi/json.lua

What's added

• Pretty encode
• Prioritizing & sorting keys

Example

local o = { d = 4, c = 2, first = 1, a = '123', second = 2}
print(json.encode(o, {
  pretty = true,
  keys = {'first', 'second'}
}))

{
  "first": 1,
  "second": 2,
  "a": "123",
  "c": 2,
  "d": 4
}

local level = {
  name = "test level",
  layers = {
    {
      type = "tile",
      width = 5,
      height = 3,
      data = {
        {1, 1, 1, 2, 3},
        {4, 1, 2, 3, 4},
        {3, 4, 5, 1, 3}
      }
    },
    {
      type = "objects",
      data = {
        {
          name = "slime",
          x = 1,
          y = 2,
          opt = {
            color = {1, 0, 0},
            size = 'big'
          }
        },
        {
          name = "bunny",
          x = 3,
          y = 2,
          opt = {
            color = {1, 1, 1},
            size = 'small'
          }
        },
      }
    }
  }
}

local keys = {"type", "name", "x", "y", "width", "height", "layers", "opt", "data"}
print(json.encode(level, {
  pretty = true,
  indent = "  ",
  keys = keys,
}))
