Marius Mutu 3a234b5240 Remove FXP files from tracking and update gitignore
- Remove nfjson/nfjsonread.FXP from git tracking
- Add Python cache patterns (__pycache__/, *.py[cod], *$py.class)
- Add environment file patterns (.env, .env.local, .env.*.local)
- Reorganize project structure with VFP files moved to vfp/ directory
- Add comprehensive database scripts and documentation

Raw Blame History

*-------------------------------------------------------------------
* Created by Marco Plaza @vfp2Nofox
* ver 1.100 - 24/02/2016
* enabled collection processing
* ver 1.101 - 24/02/2016
* solved indentation on nested collections
* ver 1.110 -11/03/2016
* -added support for collections inside arrays
* -user can pass aMemembersFlag value
* ( since Json is intended for DTO creation default value is 'U' )
* check amembers topic on vfp help file for usage
* changed cr to crlf
* Added Json validation ; throws error for invalid Json.
* ver 1.120
* encode control characters ( chr(0) ~ chr(31) )
