JSON.lua
This project was originally created by Jeffrey Friedl: http://regex.info/blog/lua/json
This repo is forked for LuaRocks.
Usage
By running Luarocks you will actually get a /usr/local/share/lua/5.2/JSON.lua.
luarocks install json-lua
And then you may import code like this:
JSON = require("JSON")
inspect = require("inspect")
local raw_json_text = "[1,2,[3,4]]"
local lua_value = JSON:decode(raw_json_text) -- decode example
local raw_json_text = JSON:encode(lua_value) -- encode example
local pretty_json_text = JSON:encode_pretty(lua_value) -- "pretty printed" version
print(inspect(lua_value))
print(inspect(raw_json_text))
print(inspect(pretty_json_text))Output:
{ 1, 2, { 3, 4 } }
"[1,2,[3,4]]"
"[ 1, 2, [ 3, 4 ] ]"
Notice that encode_pretty is not indented style. And it's a bug need to be fixed.
array_newline option
local pretty_json_text = JSON:encode_pretty(lua_value, nil,
{ pretty = true, align_keys = false, array_newline = true, indent = "| " })
print(pretty_json_text)Output:
[
| 1,
| 2,
| [
| | 3,
| | 4
| ]
]
