d3-create-json

Create json in your d3 program.

• To install
  • You can either
    • clone this repository to your system
      • click the "Clone or Download" button & copy the url
      • on your system change to the directory where you want the directory --> cd projects --> git clone past_url_here
        • will create d3-create-json directory...in your current directory --> cd d3-create-json
    • or just copy/paste the code from the browser for each file to your d3 system. I'm using d3/linux.
  • Then flash compile-catalog each subroutine/d3 program.
  • DEPENDENCY
    • I called a few string subroutines in the code. --> richardottinger/d3-string-subroutines

File Name	Subroutine	Parameters	Description
test_d3_creating_json	JSON.EXAMPLE	None	Main d3 program that makes calls to the subroutines to generate json.
json_add_pair_sub	JSON.ADD.PAIR	KV_ARRAY, KEY, VALUE, VALUE.FLAG	* Add a key/value pair to the KV_ARRAY dynamic array. VALUE.FLAG is used to determine if value should be quoted or not. 1=QUOTED, 0=NOT.QUOTED, or ! indicates that the value is boolean, or you can pass "" if you want the value to be tested to determine if quotes need to be added
json_array_add_object_sub	JSON.ARRAY.ADD.OBJECT	CURRENT, TOTAL, JSON_OBJECT, JSON_ARRAY	Determines whether to PREPEND [, or APPEND a ], or APPEND a comma to the JSON_OBJECT, then adds the current JSON_OBJECT to the JSON_ARRAY
json_create_object_sub	JSON.CREATE.OBJECT	KV_ARRAY, JSON_OBJECT	Returns a JSON_OBJECT that contains {key/value pairs}

• This program was designed to build the json data structure by appending data in json format to a string as a program is being executed.
• This program was NOT designed to convert a large complex dynamic array to a json data structure.
• But you should be able to loop through your existing dynamic array, and build your json string using these subroutines.
  • you might have to
    • pull data out of your array
    • create a new dynamic array that represents the <X,1=key>,<X,2=value> format for one record at a time.
• alternatively use JSON.ADD.PAIR to help build the dynamic array.
  • Each call to JSON.ADD.PAIR will add a new key/value pair to the next attribute in the dynamic array.
• convert that new dynamic array to a json object using JSON.CREATE.OBJECT
• Then add that json object to a json array of objects using JSON.ARRAY.ADD.OBJECT
• To create an json array of objects : see Example 1 in JSON.EXAMPLE d3 program
• Create a simple json object that is assigned to a key Example 2
• Create a json object with no key Example 3

Below is the output of JSON.EXAMPLE d3 program
