• Smart Indentation & Pairing: Python-like clean indentation rules, auto-closing quotes, brackets, and colons.
• Official Icons: Distinctive FrontLang file icon for .ft files in the VS Code file explorer.
• Code Snippets: Fast completions for functions (fn), structs, loops, control flow, and UI components (std:ui, std:gui).

  • F5 / Ctrl+F5: Run active FrontLang file in the integrated terminal.
  • Editor title bar Play button: Instant file execution.
  • Context menu shortcuts: Run FrontLang File and Check FrontLang File.
