JsonText

IJsonText renders a JSON string with consistent indentation and syntax-highlighting for keys, strings, numbers, booleans, and null.

When to use

• API response viewers in CLIs.
• Config dump commands.
• Inspecting structured logs.

Basic usage

var
  jsonText : IJsonText;
begin
  jsonText := Widgets.Json(
    '{"name":"Vincent","skills":["Delphi","Pascal"],"active":true}');
  AnsiConsole.Write(jsonText);
end;

Renders (in colour):

{
  "name": "Vincent",
  "skills": ["Delphi", "Pascal"],
  "active": true
}

with keys in one colour, strings in another, numbers/booleans/null in a third, etc.
