A lightweight JSON library for Lua
|
|
|
|
|
|
## Features
|
|
* Pure Lua implementation
|
|
* Tiny: around 270sloc, 8kb
|
|
* 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
