An Amusing New Year's Eve

Deus In Machina • 36 implied HN points • 01 Jan 26
🕹 Technology Software
  1. PowerShell can call native C libraries through .NET P/Invoke, letting you bind libraries like raylib with just a .ps1 script and inline C# declarations.
  2. There are practical gotchas: types created with Add-Type can't be redefined in the same session. Platform-specific issues (like Wayland) can also break input functions, so you'll need restarts, renaming, namespaces, or a compiled DLL as workarounds.
  3. This is a fun way to build small demos — the example shows a Pong-like game — but the approach is clumsy for larger projects because of manual input handling and P/Invoke maintenance.
