WvdS FPC RAD Studio supports various build targets for different platforms.

Native desktop applications with graphical user interface.

• Compiler: Free Pascal Compiler (FPC)
• UI Framework: LCL (Lazarus Component Library)
• Output: .exe (Windows), Binary (Linux/macOS)

PXAML → IR → GUI Renderer → LCL Controls

Supported Controls:

• All standard LCL controls
• Custom WvdS Controls
• Native widgets per platform

[build]
target=gui
platform=windows-x64
 
[gui]
widgetset=win32  # or: gtk2, qt5, cocoa

Terminal-based user interfaces for servers and CLI.

• Compiler: Free Pascal Compiler (FPC)
• UI Framework: WvdS TUI Framework
• Output: Native Binary with ANSI/VT100 output

PXAML → IR → TUI Renderer → ANSI Escape Sequences

Supported Controls:

• TextBlock, Label
• TextBox (single-line input)
• Button (with keyboard navigation)
• ListBox, Table
• ProgressBar
• Border, Panel

[build]
target=tui
platform=linux-x64
 
[tui]
colors=256  # or: 16, truecolor
unicode=true

Browser applications via pas2js transpilation.

• Compiler: pas2js
• Output: JavaScript bundle
• Runtime: Browser, Electron, PWA

PXAML → IR → Web Renderer → DOM/CSS

Supported Controls:

• All HTML-native controls
• CSS-based styling
• Flexbox/Grid layout

[build]
target=web
platform=browser
 
[web]
minify=true
sourcemaps=true

VS Code Extensions in Pascal.

• Compiler: pas2js
• Output: CommonJS module
• Runtime: VS Code Extension Host (Node.js)

• No DOM access
• VS Code API available
• WebView for UI

[build]
target=extension
platform=vscode
 
[extension]
minversion=1.85.0
