Project Galahad

YouTube Short Presentation

Developed with Delphi Florence.

Modern engineering types for Delphi, supporting Clean Architecture and pragmatic best practices.

Project Galahad aims to provide a minimal set of opt-in modern types for general Delphi usage, along with a simple, opinionated architecture for building desktop, console, and mobile applications. It remains very much a work in progress, moving toward an initial v0.1 release via the Kitae project.

The name Galahad was chosen after King Arthur's knight, pure and of great integrity, who sought the Holy Grail. The Holy Grail, in this sense, is maintainable code.

Project Galahad aims to remain lightweight, client-side, and opt-in. It is not intended to become a full-blown ORM, nor to compete with other solutions that already solve specific problems well. Instead, it offers a focused set of types to support modern coding practices in Delphi.

For example, the TScope type:

// Instead of nested try..finally blocks:
var scope: TScope;
begin
  // Automatically freed when the procedure ends
  var list := scope.Owns(TStringList.Create); 
  var map  := scope.Owns(TDictionary<string, string>.Create);
  
  // Optional custom cleanup (Go-style defer)
  scope.Defer(procedure begin 
    Writeln('Cleaning up extra resources...'); 
  end);
  
  list.Add('Galahad makes this easy.');

  // if there is an exception, list is cleaned up, otherwise we want to return it.
  Result := scope.Release(list);
end;

For a more complete and powerful general framework, see the battle-hardened Spring4D.

For backend services there are many excellent frameworks, please see DMVC, Dext, mORMot, Horse, etc.
