json2lua

A cli utility AND package to convert JSON to LUA, meaning from a .json file to a .lua file.

installation

> npm install -g json2lua

Note: To use both npm and json2lua, you must have NodeJS installed on the machine.

usage

1. as cli command

   Specify a .json to read and a .lua file name for output.

    > json2lua test.json test.lua
   

2. as package

   Install it in your project folder:

    > npm install json2lua
   

   then require it in source code and use it:

    const json2lua = require('json2lua'),
        jsonStr = `{"id":1,"name":"dog","price":200}`;
   
    //output is:
    //{["id"] = 1,["name"] = "dog",["price"] = 200}
    console.log(json2lua.fromString(jsonStr));
   

   The testing file showed usages for all 3 valid method, and the parameter dstFileName is optional, omit it if you do not need an output file.

Example

From input file test.json:

[
  {
    "id": 1,
    "name": "dot",
    "desc": "typo for dog",
    "price": 3000,
    "passwordServerOnly": "ddd",
    "skinClientOnly": "dot-123.jpg"
  },
  {
    "id": 9,
    "name": "milk",
    "desc": "feed with this",
    "price": 42,
    "passwordServerOnly": "mkkk",
    "skinClientOnly": "white.bmp"
  }
]

Got result file test.lua:

{{["id"] = 1,["name"] = "dot",["desc"] = "typo for dog",["price"] = 3000,["passwordServerOnly"] = "ddd",["skinClientOnly"] = "dot-123.jpg"},{["id"] = 9,["name"] = "milk",["desc"] = "feed with this",["price"] = 42,["passwordServerOnly"] = "mkkk",["skinClientOnly"] = "white.bmp"}}

Note: Sorry for the readability of output .lua file, for most cases, it should be read by machine, I assume that machine doesn't complain.
