Delphi JsonToDelphiClass Wiki

JsonToDelphiClass converts a representative JSON document into strongly typed Delphi or C# source code. The repository also contains the Delphi runtime used by generated DTOs, a Windows desktop application, demo-project templates, and automated tests.

Start here

• Architecture explains the compiler-style generation pipeline and the repository's major components.
• Features is the feature catalogue, including type inference, matrices, serialization, and the desktop tools.
• Getting Started shows how to build and use the desktop generator and the generator API.
• Generator Settings documents the Delphi- and C#-specific options.
• Runtime Library explains the units that generated Delphi code depends on.
• Development and Testing describes the project layout, extension points, and test suites.

The language-neutral model is the architectural boundary. Validation, source locations, type inference, nullability, object merging, and array analysis happen before a language writer chooses identifiers or target-language types.

Supported products

• Generator GUI (Generator GUI)
  VCL desktop application for interactive conversion and visualization.

• Generator library (Generator LIB)
  Shared model plus Delphi and C# generators.

• Delphi runtime (Runtime)
  JSON DTO serialization and generated-code support.

• Demo project support (Components)
  Embedded VCL/FMX templates and GUI services.

The minimum supported compiler is Delphi 2009. The checked-in build scripts currently point to a RAD Studio 37/Delphi 13 installation and may need a local path adjustment. The desktop GUI also requires the VCL.Ribbon package. Much of the runtime uses only Delphi RTL units and is designed for cross-platform generated applications.
