功能

just to it

npm i --save dson.js

var DSONJS= require('dson.js')
var d = D = DSON = dson = DSONJS.DSON
var j = J = jvd = JVD = DSONJS.JVD

var v = null
//define dson
v =	dson('games').count()
v = dson().get('name') 
//v = dson('name') 
//v = dson().get('games[0].name') 
//v = dson().select('games[0].name') 
//v = dson().draw('games[0].name') 
//v = dson().get('games[].name'))
v = dson('games[0]').test({
  		name : "='fate stay night'",
    	masters : DSON().count().test('=6')
  	})

// here your json
var json = {
  "name": "圣杯战争",
  "about": "Fate",
  "games": [
    {
      "name": "fate stay night",
      "masters": [
        {
          "name": "Shirou Emiya",
          "cnName": "卫宫士郎"
        }

        }
      ]
    }
  ]
}

(async ()=>{
    //do select
    var result = await v.doSelect(json)

    // do test
    var isSuccess = await v.doTest(json)
})

如何扩展dson

to extend one instance of DSON

var DSONJS= require('dson.js')
var d = D = DSON = dson = DSONJS.DSON
var di1 = d('name')
var di2 = d()

var json = {"name": "圣杯战争"}
//reg new method for dsonInstance 
di1.reg('hello',  (context, yourParam1,yourParam2) => {
  // your function can be async  or sync, here is sync
  //context is inner context object for dson
  // yourParam1 yourParam2 ... is your params

  //here to set result
  context.currentData = context.tempData = `${context.tempData},hello ${yourParam1} ${yourParam2}`
  //more details in document
})

di1.hello('world' , '!!!!')

//here error
di2.hello('ni','hao')

di1.doSelect(json).then(d=>{ console.log(d)})
//圣杯战争,hello world !!!!

to extend DSON globally

var DSONJS= require('dson.js')
var d = D = DSON = dson = DSONJS.DSON

var json = {"name": "圣杯战争"}

//reg new method for DSON
d.reg('hi', async (context, yourParam1,yourParam2) => {
  context.currentData = context.tempData = `${context.tempData},hello ${yourParam1} ${yourParam2}`
})

var di3 = d('name')
var di4 = d('name')

di3.hi('ni','hao')
di4.hi(1,2,3)

di3.doSelect(json).then(d=>{ console.log(d)})
di4.doSelect(json).then(d=>{ console.log(d)})
//圣杯战争,hi ni hao
//圣杯战争,hi 1 2

examples: 1. api.dson.js 扩展dson，使其支持api调用

to extend method preExe

var DSONJS= require('dson.js')
var d = D = DSON = dson = DSONJS.DSON

D.reg('$test', function(dsonObj, p1){
    console.log(p1)
})

d('test2').set('abc' , {hello : 1}).$test('yesyes')
