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) - Tiny: around 280sloc, 9kb
- Proper error messages, eg:
expected '}' or ',' at line 203 col 30
Usage
The json.lua file should be dropped into an existing project
and required by it:
json = require "json"
The library provides the following functions:
json.encode(value)
Returns a string representing value encoded in JSON.
json.encode({ 1, 2, 3, { x = 10 } }) -- Returns '[1,2,3,{"x":10}]'
json.decode(str)
Returns a value representing the decoded JSON string.
json.decode('[1,2,3,{"x":10}]') -- Returns { 1, 2, 3, { x = 10 } }
Notes
- Trying to encode values which are unrepresentable in JSON will never result
in type conversion or other magic: sparse arrays, tables with mixed key types
or invalid numbers (NaN, -inf, inf) will raise an error nullvalues contained within an array or object are converted toniland
are therefore lost upon decoding- Pretty encoding is not supported,
json.encode()only encodes to a compact
format
