WvdS FPC RAD Studio for VS Code

Professional Pascal development in Visual Studio Code

What is WvdS FPC RAD Studio?

WvdS FPC RAD Studio is an integrated development environment for Free Pascal, implemented as an extension suite for Visual Studio Code. The suite enables development of:

Desktop Applications - Native GUI and console applications with FPC
Web Applications - Browser-based apps via pas2js transpiler
Terminal UI - Text-based interfaces for servers and CLI tools
VSCode Extensions - Pascal-based extensions for VS Code itself

Why WvdS FPC RAD Studio?
