# ![json.lua](https://cloud.githubusercontent.com/assets/3920290/9281532/99e5e0cc-42bd-11e5-8fce-eaff2f7fc681.png)  
A lightweight JSON library for Lua


## Features
* Implemented in pure Lua: works with 5.1, 5.2, 5.3 and JIT
* Fast: generally outperforms other pure Lua JSON implementations
  ([benchmark scripts](bench/))
* Tiny: around 280sloc, 8.5kb
* Proper error messages, *eg:* `expected '}' or ',' at line 203 col 30`


## Usage
The [json.lua](json.lua?raw=1) file should be dropped into an existing project
and required by it:
```lua
json = require "json"
```
The library provides the following functions:

#### json.encode(value)
Returns a string representing `value` encoded in JSON.
```lua
json.encode({ 1, 2, 3, { x = 10 } }) -- Returns '[1,2,3,{"x":10}]'
```

#### json.decode(str)
Returns a value representing the decoded JSON string.
```lua
json.decode('[1,2,3,{"x":10}]') -- Returns { 1, 2, 3, { x = 10 } }
```

## Notes
* Tables with the key `1` set are treated as arrays when encoding
* `null` values contained within an array or object are converted to `nil` and
  are therefore lost upon decoding
* *Pretty* encoding is not supported, `json.encode()` only encodes to a compact
  format
