TLDR
-
navid-m/flightsim is a flight simulator built in a custom programming language, published on GitHub.
Key Takeaways
-
Project lives at github.com/navid-m/flightsim; minimal source metadata available beyond the repo name and description.
-
Building a non-trivial application like a flight simulator serves as a real-world stress test for a custom language.
-
The project is self-contained and open source, making it inspectable as both a language demo and a sim prototype.
Hacker News Comment Review
-
The custom language compiles to QBE IR and optionally C99; optimization of generated QBE has not been a focus yet, so performance is an open question.
-
Commenters flagged missing roll control and suggested using static lift/drag coefficients as a low-cost path toward more realistic flight dynamics.
Notable Comments
-
@amelius: “using your own programming language is the best proof that you didn’t vibe-code it”
-
@stackghost: notes conventional aircraft need direct roll control, and static lift/drag coefficients would improve fidelity without much complexity.
