Delphi — это язык общего назначения, основанный на диалекте Object Pascal, корнем которого является Borland Turbo Pascal. Он поставляется с собственной IDE, разработанной для поддержки быстрой разработки приложений (RAD).
Он позволяет создавать кросс-платформенную разработку (скомпилированную) приложений из одной базы кода. В настоящее время поддерживаются платформы Windows, OSX, iOS и Android.
Он поставляется с двумя визуальными структурами:
- VCL: Visual Component Library, специально разработанная для разработки Windows, обертывает собственные средства управления Windows и поддерживает создание пользовательских.
- FMX: межплатформенная платформа FireMonkey для всех поддерживаемых платформ

Привет, мир
Эта программа, сохраненная в файле HelloWorld.dpr , компилируется в консольное приложение, которое выводит «Hello World» на консоль:
program HelloWorld; begin WriteLn(‘Hello World’); end.
Покажите ‘Hello World’, используя VCL
Эта программа использует VCL, библиотеку компонентов интерфейса UI по умолчанию для Delphi, для печати «Hello World» в окне сообщения. VCL обертывает большинство используемых компонентов WinAPI.
Таким образом, их можно использовать намного проще, например, без необходимости работать с Window Handles.
Чтобы включить зависимость (например, Vcl.Dialogs в этом случае), добавьте блок uses включая список единиц, разделенных запятыми, заканчивающийся точкой с запятой.
program HelloWindows; uses Vcl.Dialogs; begin ShowMessage(‘Hello Windows’); end.
Показать «Hello World» с помощью WinAPI MessageBox
Эта программа использует Windows API (WinAPI) для печати «Hello World» в окне сообщения.
Чтобы включить зависимость (например, Windows в этом случае), добавьте блок uses, включая список единиц, разделенных запятыми, заканчивающийся точкой с запятой.
program HelloWorld; uses Windows; begin MessageBox(0, ‘Hello World!’, ‘Hello World!’, 0); end.
Кросс-платформенный Hello World с использованием FireMonkey
program CrossPlatformHelloWorld; uses FMX.Dialogs; begin ShowMessage(‘Hello world!’); end.
Большинство поддерживаемых Delphi платформ (Win32 / Win64 / OSX32 / Android32 / iOS32 / iOS64) также поддерживают консоль, поэтому пример WriteLn подходит для них хорошо.
Для платформ, для которых требуется графический интерфейс (любое устройство iOS и некоторые устройства Android), приведенный выше пример FireMonkey работает хорошо.
