Delphi-JsonToDelphiClass

Fixes & Features: 22th December 2020

Bugs:

Features

  • New main form. Completly rewritten.
  • Support for BSON
  • Support for Minify JSON
  • Support for multiblt output formats
  • JSON are now minifyed before posted to the validator. Means support for larger JSONs to be validated.
  • Version 3.0 released.

Fixes & Features: 11th December 2020

Bugs:

  • "id": "01010101" faulty generated a TDateTime property not string.
  • Settings.AddJsonPropertyAttributes didn't generate a Property Attribute

Features

  • JSON are now posted directly to the validator
  • Better property name generator
  • More unit tests

Fixes & Features: 24th November 2020

Bugs:

Features

  • Possibility to change the postfix of ClassNames, via Settings Dialog. Default: DTO
  • Settings Dialog rewritten to use LiveBindings
  • Create a Demo Project, using your Json Data

Fixes & Features: 22th November 2020

Bugs:

  • Demo generator didn't allways generate valid code
  • Stopped the generator from generating surplus classes.

Features

  • Non object arrays are now mapped into a TList instead of TArray
  • Added a settings dialog and settings class
  • Properties in PascalCase (Setting)
  • Allways use JsonName property annotation (Setting)
  • Support for objects with diffrents properties in an Array

Eg this JSON

{
   "ArrayTest":[
      {
           "S1":"5102"
      },
      {
           "S2":"True"
      }      
   ]
}

Generates the following DTO:

  TArrayTestDTO = class
  private
    FS1: string;
    FS2: string;
  published
    property S1: string read FS1 write FS1;
    property S2: string read FS2 write FS2;
  end;

Previous changes

  • Only floating point numbers are mapped to Double
  • Numbers are mapped to Integer or Int64 depending on their size
  • Generated code restructored, and simplified
  • Generated classes inheriteds from TJsonDTO
  • Socurce Code restructored
  • Parser logic seperated from GUI logic
  • Fixed bug in the RegEx for recognizing an ISO8601 Date
  • Serialization removed the "noise" of List i.e. includes internal properties that did not exist in the original JSON string.
  • Generated code uses TObjectList

Generates Delphi Classes based on JSON string. Just like XML Data Binding, but for JSON.

Main features

  • Build entirely on the RTL (no external dependencies) so it's cross-platform;
  • Accepts any valid JSON string, no matter how complex the object is;
  • Visualizes the structure of the JSON objects in a treeview;
  • Generates complete delphi unit (declaration and implementation), based on the JSON string input;
  • Automatically prefixes reserved Delphi words with "&" (ampersand);
  • Support for JSON string that contains empty Array;
  • Adds support code to automatically destroy complex sub types. So you don't have to manage subobject's lifetime manually;
  • Uses TObjectList to represent lists;
  • Adds helper serialization/deserialization functions;
  • Serialization and deserialization results in the same JSON structure!
  • Automatically detects date/datetime parts and maps them to TDate/TDateTime (as long as dates are ISO8601 compliant);
  • Maps floating point numbers to Double
  • Maps Number to Integer or Int64 depending on the number
  • Maps true/false values to Boolean;
  • Supports JSON pretty print to format the input string;
  • Simple and responsive GUI;
  • Automatic check for update, based on ITask (Parallel Programming Library)!
  • It's open source! You can find the source code and binary releases on GitHub.
  • If the JSON array is empty the contained type is unknown. Unit generation works only with known and supported types.
