Delphi / Object Pascal
Delphi (RAD Studio) and Free Pascal (Lazarus) keep Object Pascal alive. It is famous for Single EXE deployment and instant compilation.
When to Use
- Windows Desktop Apps: The VCL framework is still the fastest way to build native Windows GUIs.
- Legacy Maintenance: Massive industrial controllers in Europe use Delphi.
- Cross-Platform: FireMonkey (FMX) and Lazarus allow targeting Mac/Linux.
Core Concepts
VCL / LCL
Visual Component Library. Drag-and-drop UI building.
Units
interface, implementation sections. Strict modularity.
RTTI
Runtime Type Information (Reflection) was pioneered here.
Best Practices (2025)
Do:
- Use Generics:
TList<T>(modern Object Pascal). - Use
Lazarus: For open-source cross-platform development (Free Pascal 3.2+). - Manage Memory: Use
try..finallyblocks forFree.
Don't:
- Don't use
With: It makes scoping ambiguous.
