i was unable to encode a table due to some number based key properties. i modified the encode function to check for number based keys in addition to the already present string based keys. an error will still be returned if the key is neither string nor number based. it works in my cases |

README.md
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
