TOON (Token-Oriented Object Notation) support for Delphi Read more Read more about TOON
A lightweight Token-Oriented Object Notation (TOON) library for Delphi.
TOON is a compact, human-readable, token-efficient data format designed for AI / LLM workflows.
This library brings full TOON ↔ JSON ↔ Delphi RTTI object conversion into Delphi, with zero dependencies and full Win32/Win64 compatibility.
✨ Features
- Object → TOON (via RTTI, published properties)
- TOON → Object (via JSON intermediate stage)
- JSON → TOON
- TOON → JSON
- Simple fluent API via
TToonBuilder - Works on Win32 and Win64
- No external libraries required
🚀 Quick Examples
Delphi Object → TOON
type
TUser = class
private
FId: Integer;
FName: string;
published
property Id: Integer read FId write FId;
property Name: string read FName write FName;
end;
var
LUser: TUser;
LToon: string;
begin
LUser := TUser.Create;
LUser.Id := 1;
LUser.Name := 'Alice';
LToon := TToon.ObjectToToon(LUser);
{
Id: 1
Name: Alice
}
end;JSON → TOON
var
LJSON, LToon: string;
begin
LJSON := '{"users":[{"id":1,"name":"Alice"},{"id":2,"name":"Bob"}]}';
LToon := TToon.JSONToToon(LJSON);
(*
users[2]{id,name}:
1,Alice
2,Bob
*)
end;TOON → JSON
var
LToon, LJSON: string;
begin
LToon :=
'users[2]{id,name}:' + sLineBreak +
' 1,Alice' + sLineBreak +
' 2,Bob';
LJSON := TToon.ToonToJSON(LToon);
end;Fluent Builder
var
LToon, LJSON: string;
begin
LToon := TToonBuilder.FromJSON('{"x":1,"y":2}').AsToon;
LJSON := TToonBuilder.FromToon(LToon).AsJSON;
end;From Object → TOON
type
TPoint = class
private
FX: Integer;
FY: Integer;
published
property X: Integer read FX write FX;
property Y: Integer read FY write FY;
end;
var
LObj: TPoint;
LToon: string;
begin
LObj := TPoint.Create;
LObj.X := 10;
LObj.Y := 20;
LToon := TToonBuilder.FromObject(LObj).AsToon;
{
X: 10
Y: 20
}
