minor bug fix: zero item collections created as 1 empty item collection
proper indent for raw/formatted collection objects

2016/08/16:
nfJsonPerfTest:
added compiled exe
samples file ships as a separate file for you to edit
fixed bug on test prgs:
clean installs would fail due to missing temp folder on ditribution zip w/o tests\temp folder
fixed bug on collectionTest

2016/07/22:
nfJsonRead: Improved error management
CollectionTest: added new test

2016/07/20:

• Fixed bug: missing closing curly brace on collections as object member
• Updated collections program test

2016/07/09:

• Automatic cast for datetime properties ( ISO-8601 basic format & vfp compilant as described on https://en.wikipedia.org/wiki/ISO_8601#Times. )

• nfJsonToCursor Bug Fix: "Date/datetime evaluated to an invalid value" while running under "strictdate = 1" converting empty dates back from Json

2016/07/04:

• Added support for control characters encoding ( chr( 0) ~ chr(31) )

2016/05/05:

• invalid Json error shows calling program information

2016/04/02:

• complex nested objects/arrays validation
• missing object/array closures validation

2016/03/28:

• nfJsonRead performs JSON validation: invalid Json throws error indicating reason.

• nfJsonPerfTest: proper error management enabled for invalid Json input from clipboard

• nfJsonToCursor: use of strict date format

Functions & Usage:

( Each function is a single prg - No additional dependencies / Requires VFP9 )

• oJson = nfJsonRead(cJsonString , isFileName,lReviveCollections)

• cJsonString = nfJsonCreate(oVfp, lFormattedOutput, lNoNullArrayItems,cRootName,aMembersFlag)

• nfJsonToCursor(cJson, cCursorName , lForceImportFromArray) ( creates cursor back from Json created using nfCursorToJson4vfp )

• nfCursorToJson4vfp()&& converts current open table/cursor to Json suitable for later use of nfJsonToCursor()

• nfCursorToJson(lReturnArray, lArrayofValues, lIncludestruct, lFormattedOutput)&& converts current open table/cursor to Json

• nfCursorToObject(lCopyToArray, lIncludeStruct)

Tests & Sample files:

• nfJsonPerfTest.prg: just run it and choose one of the embedded json samples from the list to check performance on your pc. ( Allows you to parse Json from clipboard too. )

• examples.prg will parse the next Json files included in JsonSamples folder. just run from test folder and see sample code and output.

• collectionTest.prg: creates a complex collection , converts it to Json and back to vfp.

• Sample Json files included:
  • youtubesearch.json
  • cycloneForecast.json
  • dropbox.json
  • googleMapsDistance.json
  • iphone photo.json
  • mapquest.json
  • mySimpleArray.json
  • tweeter.json
  • weatherService.json
  • yahooweather.json
